TITLE: COMPARE STUDY ON THE PERFORMANCE OF ACOUSTIC INSULATION ELEMENT FOR GUIDE RAIL CONNECTIONS USING ANCHOR CHANNELS WITH CHANNEL BOLTS
AUTHOR(S): Mazen Ayoubi1 and Sacha Sobotta1, PohlCon GmbH, Berlin
ABSTRACT: The resulting operational noise of elevators can be an acoustical impairment to the usability of rooms in the vicinity of the elevator shaft. The available technological efforts to acoustically insulate elevator components are not able to prevent significant transmission of noise and vibration to the elevator shaft walls. The JORDAHL Acoustic Insulation element (JAI) is designed to decouple the transmission chain of noise and vibration, and so to prevent the vibro-acoustic transmissions reaching the elevator wall and building structure. Compare study on the performance of this element using acoustic tests taking into account the other nowadays available elements and solutions have been carried on different types of JORDAHL Acoustic Insulation. The most important scientific and practical results of the investigations will be summarized and discussed.

ABSTRACT: In this paper, we present a new approach applying computer vision methods to image data acquired with depth perception cameras to map the interior of the elevator, detect the position and the state of the door and to detect objects in the door area. The depth data is used to determine the elevator cabin as a safety cube, i.e., the position of the door, layout of the elevator, and so on, while color data further enhances the detection of new objects. The approach can detect the state of the elevator door as either opened or closed, while no object is blocking the view to the door, as well as successfully identify objects blocking an open door. This elevator monitoring proves to be relevant for the determination of the elevator state, safety as well as aspects of predictive maintenance.

AUTHOR(S): Darren Batey, KONE Industrial Ltd
ABSTRACT: An accurate site survey is the first step in creating a successful engineered modernization. In the past site surveys have used tape measures and pen and paper, this has recently been changed to use laser measurements and mobile devices but basically the process has remained the same – just the media has changed. For complex projects KONE have started to use 3D scanning to improve the site survey accuracy, minimize disruption to our customers, improve the safety of our personnel and increase overall productivity of the engineering.
TITLE: FUTURE OF ELEVATOR EMERGENCY COMMUNICATION AFTER TRADITIONAL FIXED LINES, 2G AND 3G NETWORKS SUNSET
AUTHOR(S): Petr Chovanek, 2N Telekomunikace a.s
COUNTRY: Czech Republic
Architecture and basis of current emergency communication systems in elevators are built on obsolete analogue technology and do not provide options how to keep up with ever demanding regulations.Elevator industry must embrace modern IP technology which will open new possibilities how elevators are operated, managed, and maintained. Shutdown of 2G and 3G should serve as an accelerator for the transition to IP. In addition, using Voice over IP (VoIP) technology for voice transmission will provide more reliable DTMF signal processing and offer a much broader feature set. Thanks to multimedia support you can also easily transmit video and text information along with voice. With IP and modern cloud infrastructure you can manage millions of devices from central place securely. You will have a full control over your systems, all configuration changes, upgrades, and new features will be installed without necessity to train have any specific IP know-how your people and travel on-site.
TITLE: ENHANCING ESCALATOR SAFETY WITH THE USE OF OPTIC-FIBER SENSING TECHNOLOGY AND 1D CONVOLUTIONAL NEURAL NETWORKS
AUTHOR(S): William T.W. Au1, K.C. Cheng2, W.H. Chung2, 3, Y.K. Yu3, H.Y.

COUNTRY: Hong Kong, China
ABSTRACT: Reliable and safe operation of escalators is vital for every metropolitan city. Sensing systems making use of optical-fibers can effectively and reliably monitor the operation conditions of in-service escalators to alert any impending equipment failures or breakdowns, capable of giving advance notices for corrective measures to enhance reliability and availability of the installation. The innovative optical-fiber sensing and data analytic approach capable of early identification of faults, including brake malfunction, step dislocation due to jamming of foreign objects, defective step rollers and handrails has been demonstrated. Abnormal noise signatures of an escalator in a metro-station have been recorded and analyzed to signify impending failures of escalator components, thus enabling early rectification of the defective parts and eliminating of passenger injury or equipment damage due to failure of defective components. Coupled with artificial intelligence, the system forms an effective predictive maintenance system to reduce escalator downtime and to eliminate unnecessary inspections to realize cost savings over traditional time-based preventive maintenance
TITLE: AN HISTORICAL OVERVIEW OF MULTIDIRECTIONAL, ROPE-LESS ELEVATOR SYSTEMS
AUTHOR(S): Dr. Lee E. Gray, The University of North Carolina at Charlotte
COUNRY: United States
ABSTRACT: Every profession embraces a set of elusive goals that constitute what may be thought of as “Holy Grail” projects. For the vertical transportation industry this includes the search for an elevator system that moves passengers vertically and horizontally. The contemporary search for this Holy Grail suggests that an historical overview could provide a useful lens through which to understand current events. This paper explores a variety of proposed solutions to ropeless, multi-direction elevator systems.
TITLE: SIMULATION BASED DESIGN OF TRANSPORTATION SYSTEMS IN BUILDINGS
AUTHOR(S): Henri Hakonen, Lic.Sc. (Tech.) & Juha-Matti Kuusinen, D.Sc. (Tech.), and Janne Sorsa, D.Sc. (Tech) KONE Corporation
ABSTRACT: This paper describes some key advances in modelling and simulating people flow in buildings including multiple transportation and access devices such as elevators, escalators, staircases, turnstiles and doors. The flow consists of autonomous agents whose routes through the building depend on their physical and behavioural characteristics such as walking speed, the ability to use certain devices and preference about different route alternatives. These computational simulation models have been combined with game engine technology to develop a new simulation tool called the People Flow Simulator enabling realistic agent movement, high-quality 3D visualizations and easier assessment and communication of the simulation results for the design of better functioning buildings.
TITLE: VERTICAL HIGH SCHOOLS – THE FUTURE OR FAILURE?
AUTHOR(S): Scott Hampson, Arup
ABSTRACT: Vertical schools are becoming a necessity in in growing and crowded cities and can range from 4 floors to 20 floors and up to 2000 students. With the complexities of building population, passenger demands and height, vertical schools present multiple technical challenges for the vertical transportation engineer.
Arup was engaged to deliver a vertical transportation solution for a large vertical high school in Sydney Australia and our challenge was to meet the performance requirements of stakeholders while also being considerate of spatial and cost constraints. My paper will review the full life cycle of the project and cover our design approach, client engagement, challenges, solutions, final operation, and lessons learned.
TITLE: INSPIRATION FROM THE SHARD: TIME-SHARING DUAL CARS MULTIFUNCTIONAL LIFT DESIGN FOR SLENDER LUXURY RESIDENTIAL TOWERS
AUTHOR(S): Hongliang Liang, Aliang Lift Design Studio Ltd, UK
Abstract: The author developed two unique methods for vertical transportation design, called ´Disadvantage Transformation´ and ´Time Space Deployment´. By using these methods, the author has successfully delivered three VT system designs for all kind of high-rise residential towers. This paper introduces the second design which was also inspired by the VT design in the Shard, London: the lift looks similar to a double-deck lift, but the loading into the two cars would never happen simultaneously. At peak times, the lower car of a time-sharing lift works as a passenger lift under destination group control at low-rise front lobbies. At off-peak times, the upper car works as a simplex service lift in independent mode at fire-protected rear lobbies whilst also working as a firefighting/evacuation lift at rear lobbies at any time by activating the relevant switches.

AUTHOR(S): Alexander Hutler, Chr. Mayr GmbH + Co. KG
Abstract: For more than 30 years, the company Mayr power transmission has been a successful innovator in the area of elevator brakes. The reliable solutions from Mauerstetten / Germany have proven themselves thousandfold in the field – all over the world. The elevator brakes with their unique noise damping system have thus also contributed significantly to the company’s 125-year success story.
The following paper intends to illustrate not only how the requirements for elevator brakes have changed over the years, but also which requirements are still essential today and which brake solutions for elevator traction machines have already been developed to meet them.
Based on many years of experience as a manufacturer of safety brakes (including multiple global projects for leading OEMs in the industry), the paper aims to summarize the key factors that need to be taken into consideration when selecting safety components today (here based on type-tested elevator brakes) lease.
TITLE: FINITE ELEMENT ANALYSIS OF GLASS PANELS WITH BOLTED CONNECTIONS DESIGNED FOR A RUNNING CAR
AUTHOR(S): Eren Kalay1, C. Erdem Imrak1 and Adem Candas1, 1,2,3ITU Faculty of Mechanical Engineering
ABSTRACT: Nowadays, there is a growing trend towards increasing the transparency of buildings. With the developing technology now it is possible to see this trthe end in lift sector also. Increasing glass industry has revealed the term structural glass, which consists of two tempered pieces of glass with the layer of PVB. Designers have created four point fixed glass facade system for lifts with using the structural glasses to increase aesthetic view. But fixed holes create stress concentration that could lead to catastrophic failures. The aim of this paper is to investigate stress distribution around the drilled holes of lift’s glass facade while running.

This document explains status of international standardization of lifts which may be used for evacuation of a building. Document compares different evacuation operation functions which are specified in published standard documents CEN/TS 81-76, ISO/TS 18870, ASME A17.1 / CSA B44 and CEN prEN 81-76. Document introduces potential use cases of different evacuation operation modes for different types of buildings and for different size and type of population.
TITILE: ENHANCEMENT OF AUTO-RECOVERY FUNCTION FOR ELEVATORS AFTER EARTHQUAKE
AUTHOR(S): Shohei Kondo, Shuichi Hayakawa and Junji Takeda, Toshiba Elevator and Building Systems Corporation
ABSTRACT: Toshiba Elevator and Building Systems Corporation has already commercialized an auto-recovery function for elevator systems that is activated by an earthquake, performing a self-diagnosis to tentatively restore elevators to normal service. We have now enhanced this system by positioning seismic detectors in order to measure seismic waves directly for comparison with the seismic design criteria of the equipment. In the case of a tremor smaller than the seismic design standard, the new system facilitates the provision of a field service for temporary and safe restoration of the elevator if the automatic self-diagnosis operation detects no anomaly.
TITLE: VERTICAL EQUIPMENT MAINTENANCE
AUTHOR(S): John W. Koshak, QEC, CEI eMCP, LLC – Managing Member
COUNTRY: United States
ABSTRACT: The Safety Code for Elevators and Escalators in the United States and Canada, ASME A17.1/CSA B44, includes Section 8.6, the Maintenance, Repair, Replacement and Testing section. It applies to all new and existing equipment to ensure maintenance is performed on critical components of vertical equipment to reduce hazard. It prescribes a Maintenance Control Program (MCP), a documented set of maintenance tasks, procedures, examinations, tests and records to ensure that equipment is maintained in compliance with the requirements of Code. It requires establishing the intervals between performing a maintenance task, recording maintenance performed, recording repairs, replacements, alterations, call backs, oil loss, and several other items. Authorities Having Jurisdictions in the United States and Regulatory Authorities in Canada (AHJs/RAs) require owners to provide and follow MCPs. This paper details the Code and a system that fully complies with these requirements, eMCP.
TITLE: RETHINKING ELEVATOR CONCEPT, PART OF THE BUILDING AS A SYSTEM WITH SOCIAL AND PHYSICAL ENVIRONMENT
AUTHOR(S): Magdalena Krstanoski, Concept2Solution, LLC
COUNTRY: United States
ABSTRACT: Building projects are not necessarily homogeneous in nature. Vertical transportation selection should be a thoughtful result of an individualized approach, result of a conducted analyses based on the project requirements and understanding the building structure as a system, physical and social characteristics of area of application. Internal and external environments that influence design are complex reflection of the social and physical factors, visualizing the conditions to meet and to exceed the project and the performance requirements. The paper also explores Purchasing Power Parity (PPP) as related to the multicultural environments, global product applicability and factors that affect the Law of One Price. At the same time holistically touches major challenges in the elevator industry today including new design strategies, labor, management, cost, transportation safety, codes and maintenance.
TITLE: DIVIDER BEAM DESIGN AS PART OF THE STANDARD ELEVATOR DESIGN
AUTHOR(S): Michael Merz, Hilti Corporation, Principality of Liechtenstein
ABSTRACT: Divider beams can create headaches for project managers who must provide separation walls in a hoistway that should host two or more elevators. To avoid accidents during the handling and welding of heavy steel material, the installation of the beams is often passed to the general contractor or a subcontractor. Involving a third party requires design drawings, a bidding process, coordination, inspection for acceptance and, finally, the complaint procedure. This paper introduces a new design method for installing divider beams as part of the elevator installation process and discusses the multiple benefits of this innovative solution.
TITLE: CONDITION MONITORING OF ELEVATOR USING DEEP LEARNING AND FREQUENCY ANALYSIS APPROACH
AUTHOR(S): Krishna Mohan Mishra1, John-Eric Saxen2, Jerker Bjorkqvist2, and Kalevi J. Huhtala1, 1Unit of Automation Technology and Mechanical Engineering, Tampere University, Tampere, Finland, 2Department of Information Sciences, Abo Akademi University, Turku, Finland
ABSTACT: In this research, we propose automated deep learning feature extraction technique to calculate new features from fast fourier transform (FFT) of data from an accelerometer sensor attached to an elevator car. Data labelling is performed with the information provided by maintenance data. Calculated features attached with class variables are classified using random forest algorithm. We have achieved 100% accuracy in fault detection along with avoiding false alarms based on new extracted deep features, which outperforms results using existing features. This research will help various predictive maintenance systems to detect false alarms, which will in turn reduce unnecessary visits of service technicians to installation sites.

AUTHOR(S): Akira Nagao*, Takashi Abe*, Katsuhiro Shimada*, Tomoki Kariya, Akihiro Yamaguchi 2 , and Satoshi Ihara 2 , 1Hitachi Building Systems Co., Ltd., Japan, 2 Hitachi Ltd., Japan
ABSTRACT: In recent years, mobility industry is applying adhesion technology to improve vehicle body rigidity, ride comfort and simplify structure of components. In elevator, car floor is main structure that contributes to rigidity of car and affects ride comfort. By applying adhesion technology to car floor components, aim to increase rigidity of entire car and simplify parts configuration. In this study, we selected adhesive with high long-term reliability, used CZM analysis (Cohesive Zone Model) simulating peeling of adhesive structure, as adhesive strength evaluation and applied strength evaluation method that considers fatigue stress. This report shows the evaluation method for above contents.
TITLE: THE STATE-OF-THE-ART AND FUTURE OF SAFE SHAFT INFORMATION SYSTEMS
AUTHOR(S): Stephan Rohr, ELGO Batscale AG
ABSTRACT: With the introduction of PESSRAL in the European Standard the future of safety systems started to be part of elevators. The absolute positioning device gets a more and more important role on that because with a safe position and speed a lot of the SIL rated functions can be implemented. To mention some: Unintended car movement, terminal slow down, inspection supervision and a lot more. This paper gives an overview of the safety functions which are available on the market and an outlook of electronic safety functions for elevators.
TITLE: THE SIMULATION OF SEISMIC EFFECTS ON GUIDE RAIL FASTENERS AND RE-DESIGN OF BRACKETS
AUTHOR(S): Abdülmelik Sancak1, Adem Candaş1, C. Erdem İmrak1, Sefa Targıt2, 1ITU Elevator Technologies Laboratory, Istanbul, Turkey, 2ASRAY, Gebze/Kocaeli, Turkey
ABSTRACT: In public buildings such as hospitals, universities, schools, people and equipment that need to be evacuated after an earthquake can be hardly transported.The brackets that connect and secure the elevator car and counterweight rails to the walls of the concrete elevator shaft are damaged as a result of the seismic waves. Hence, elevators cannot be used because the car and counterweight of the elevator cannot run on the rails. Critical buildings such as hospitals, public and equipment that need to be evacuated after an earthquake can be hardly transported. In this study, simulations were conducted to determine the effect of earthquake loads on the bracket parts. Finally, bracket elements were re-designed to withstand earthquake loads to use the elevator after being affected.
TITLE: STUDY ON LINEAR PERMANENT MAGNET SYNCHRONOUS MACHINES FOR ROPELESS LIFTS
AUTHOR(S): Albert So1 and W.L. Chan2, International Association of Elevator Engineers (HK-China Branch), 1University of Northampton, 2The Hong Kong Polytechnic University. COUNTRY: UK, Hong Kong
ABSTRACT: It is rather certain that multi-dimensional lift systems will soon dominate the lift industry in coming years due to the first successful development of MULTITM. To facilitate such a design, the concept of ropeless lifts has to be implemented while the adoption of linear permanent magnet synchronous machines (LPMSMs) such as those used in the MULTITM system is an obvious choice. Without the existence of hoisting ropes, lift cars not only can travel along all three directions, but the number of which in one hoistway is not limited to two. We carried out a series of academic studies to evaluate the performance of such LPMSMs under various conditions by simulation. In this paper, which is a summary of our previous works with some new input, the control method to realize the required kinematics under a full-load up journey, the impact of different electrical parameters on the power consumption, and most important, the analytical solution associated with emergency operation under a genuine power failure will be discussed. Machine models of surface mounted and salient permanent magnets will also be considered. This is basically a review paper based on a series of previous publications of the authors.
TITLE: A PROCEDURE TO ESTIMATE ELEVATOR ENERGY CONSUMPTION USING TRAFFIC SIMULATION
AUTHOR(S): Janne Sorsa, KONE Industrial Ltd.
ABSTRACT: Current methods estimate the annual energy consumption of an elevator using simplifying modelling assumptions. The assumptions, however, may greatly differ from elevators operating in groups in high-rise buildings under complex traffic conditions and intensive use. For such cases, elevator traffic simulation provides an accurate method to evaluate energy consumption per typical day in operation. This article describes a procedure to first simulate a typical daily passenger demand profile and then to evaluate energy consumption from elevator trips occurring in simulation. In addition, numerical examples show how the procedure can be applied in practice to compare different elevator products.
TITLE: ELEVATOR EVACUATION OF TALL BUILDINGS
AUTHOR(S): Peter Sumner, Birmingham
COUNTRY: United Kingdom
ABSTRACT: The general rule 20 years ago was to evacuate building occupants by stairs alone although, all tall buildings had Emergency Elevators to assist the Fire Service in fighting fires, they were not generally used for evacuation. Post 9/11/2001, there has been an awakening to the need to speed up and make safer the evacuation of all building occupants and many tall buildings now contain Elevators designed for Evacuation and in some cases special Evacuation Elevators.
Back in 2002 I wrote a paper entitled “Fire-fighting and Evacuation Lifts. Exploring the Concept of using Lifts to escape building fires”, and have championed the need to design Elevators, and Elevator systems to assist the evacuation of tall buildings ever since. This paper expands on my early work and discusses the design process that is required to incorporate Elevator Evacuation into the design of tall buildings.
TITLE: ESTIMATION OF PARAMETERS AFFECTING RIDE COMFORT IN ELEVATOR
AUTHOR(S): Keisuke Terada, Yoshitake Kamijo, and Yoshiyuki Iwata, Toshiba Infrastructure Systems & Solutions Corporation, Toshiba-cho, Fuchu-shi, Tokyo 183-8511, Japan COUNTRY: Japan
ABSTRACT: Among the demands for energy saving and high efficiency improvement of equipment, comfort is required as added value. Vibration and noise during elevator travel propagate into the car, which induces a feeling of ear blockage and car shaking. As a result, the ride comfort, which is one of the comforts, is reduced. In this paper, we focus on the ride comfort of the elevator. We combine human subjective evaluation and objective evaluation by physical quantity to extract parameters that affect ride comfort. As a method, each index is extracted by multivariate analysis of sensory evaluation data and physical evaluation data, and they are subjected to multiple regression analysis to make association. As a result, this paper shows that the parameter to be affected is longitudinal acceleration of the human being.
TITLE: IOT TAKES THE ELEVATOR WORLD INTO INDUSTRY 5.0: ELEVATOR WIRE ROPES INSPECTION: REGULATIONS, STATE OF THE ART, STATISTICS, A QUANTUM LEAP OF SYSTEM UTILIZATION AND YIELD
AUTHOR(S): Christian-Erik Thöny, CEDES Group, Science Park, 7302 Landquart
ABSTRACT: IoT has been enabled in the last very few years by powerful cloud systems. Almost no limits in bandwidth and data transfer rates allow “real-time” condition monitoring & controlling. The health, safety and yield of an e.g., hotel vertical transportation system, or simple single elevator application, will be significantly different to the pre-IoT aera. The consistent connected machinery generates “real-time” life data which continuously ensure shortest door open-close cycles, early detects wrong trends of a sub-system, warns of potentially dangerous situations and helps optimizing energy consumption. AI thereby distinguishes between problem causing sub-systems and components. That’s all a decisive contribution to a new aera of PLM and finally Sustainability – Industry 5.0. The origin of all such analysis and finally intelligent conclusions are sensor fusions; the micro (eco)system, the WSN – wireless sensor networks; the macro (eco)system and finally the total network of everything – the IoT COP, the IoT common operating system.
TITLE: ELEVATORS ON THE MOON ARE CLOSER THAN YOU THINK
AUTHOR(S): Yuval Valiano-Rips1, Maya Glickman-Pariente2, 1Rips Elevators Group (Rips engineering Ltd), Israel, 2SPACECIALIST Ltd, Israel
ABSTRACT: Few space programs have already been initiated and funded to take humans to the moon, Mars and beyond, the major one being Artemis Mission that is set on building inhabited base camps, for science and mining, on the lunar surface.
Taking huge amounts of equipment down from a 50m high landers, traveling to the underground camps or mines, all require us to reimagine elevators in the harsh environment of space.
This is not science fiction- the first elevators will be operational on the moon during the expected landing of SpaceX landers by the end of this decade, under the Arthemis program.
In our paper, we have researched the challenges for this new market, and proposed a roadmap for upgrading the elevator industry to the space era. This paper is a call for action for our industry.
TITLE: CONSULTANT DESIGN CHALLENGES IN ASIA DUE TO MANUFACTURERS’ DIFFERENCES
AUTHOR(S): K. Rajah Venkatraman, Vinay Venkatraman, Fortune Consultants
ABSTRACT: The Consultant faces a challenge by the developer/architect in providing space for vertical transportation. For example, often floor plates and high density become limiting factors for VT Design. Additionally, in Asia, different suppliers/manufacturers have their design constraints which calls for different dimensional and other requirements varying between each other. These and other differences between suppliers are the challenges listed out as major difficulties for the consultant in achieving optimal design. To strengthen this argument and to look for a commonality between the suppliers, various segments are being logically presented in the paper touching upon the various aspects of VT Design.
TITLE: ELEVATOR WIRE ROPES INSPECTION: REGULATIONS, STATE OF THE ART, STATISTICS
AUTHOR(S): Bruno Vusini, Daniel Rossi, Tommaso Bertani, AMC Instruments
ABSTRACT: The traction cables of lifts play a very important role in the safety of people. Only in Italy we have about 900,000 working lifts, which make an average of more than 1 million trips per day. This means that millions of people rely on the proper operation, and maintenance, of all the components of this particular (and let’s say intrinsically safe) machine. There are, of course, laws and standards that must correctly regulate the maintenance operations that allow the elevator to operate as correctly and safely as possible, and it is often taken for granted that the maintenance technicians operate in total accordance with these documents. International standards, such as the ISO4344, require the identification of very little damages that are really difficult to be visually identified and for this reason a real rope visual inspection takes hours to be completed.
Fortunately, technology is advancing and, concerning rope analysis, much more efficient inspection methods have appeared on the market in the last 10 years.
The purpose of this article is to provide basic information about the inspection market, laws and standards, and the results obtained over a period of more than ten years, from which both the advantages of using advanced methods, and the total inefficiency of antiquated analysis methods are evident.
TITLE: HOW TO SETUP SAFETY DEVICES IN AN ELEVATOR
AUTHOR(S): Stephan Rohr 1, Christopher Bormann 2, 1 ELGO Batscale AG, Liechtenstein, 2 ELGO Electronic GmbH
ABSTRACT: With the introduction of PESSRAL in elevator systems also a big change was connected. From mainly mechanics to electronics and further on to SIL rated electronics. In this workshop an overview is given how safety devices are commissioned. How shaft parameters are “teached” and how elevators are setup from commissioning to normal running mode.
TITLE: REVERSE ENGINEERING – REMOTE MONITORING OF ELEVATORS AND AUTHORISED THIRD-PARTY ACCESS TO ELEVATOR DATA.
AUTHOR(S): Esko Kilpinen, Modusolutions.
ABSTRACT: Today, most new elevators have inbuilt IoT capabilities and send elevator performance data to the manufacturers’ IoT cloud-based monitoring applications. Authorised third-party usage is limited to the remote monitoring solution provided by the manufacturer. Building owners can access the remote monitoring system while the manufacturer services the elevator. Once the elevator maintenance agreement is transferred to another service company, the data flow stops to the building owner and the third-party service company. The building owners see this as a block to competition in the service business.
On the other hand, older controllers have had no online connectivity, and remote monitoring has not been possible. Both problems are being solved by third-party reverse-engineered products connecting new and old controllers to third-party cloud solutions. Questions like cyber security, product liability, ownership of elevator data, or open competition remain unanswered. Is this a sensible or safe solution for an industry renowned for safety, or could an industry-wide IoT standard be the way forward?
