What are the Advantages of Elevator IoT? The Development Process of Elevator IoT

The elevator IoT is a concept proposed to solve the current elevator safety problems. The data acquisition part, the data transmission part, the central processing part and the application software together constitute a complete elevator IoT monitoring system. The collector collects the elevator operation data for analysis and uploads it to the Internet monitoring center, combined with the platform application software, so as to realize the real-time and effective supervision and maintenance of the elevator by all relevant units.

Elevator IoT
1. The development process of elevator IoT
Since the concept of the Internet of Things was born, the elevator IoT has been explored for nearly 20 years. With the advancement of global urbanization, more and more high-rise buildings have emerged, and elevators have become the most frequently used transportation equipment for people to travel. Although elevators have limited speed, buffers, safety gears and other safety devices, safety accidents still occur frequently, making elevator safety predictable and becoming more and more urgent.
In the early stage of the development of elevator IoT, most of them were in the most basic fault monitoring. The earliest elevator to implement remote monitoring service was Hitachi, Japan. Since about 2000, it has been connected to the MAS system through a telephone line, which can realize remote response to faults. Later, with the popularity of mobile phones, OTIS 400 phones were opened, but there was often no mobile phone signal in the elevator, and the phone could not be made when people were trapped. Therefore, the elevator five-party call was developed later, but the five-party call that requires large-scale wiring is not ideal in the actual implementation process, and many elevator five-party calls are just decorations.
With the development of control technology, manufacturers can achieve fault monitoring by collecting fault signals on the control cabinet. The main board of the elevator transitions from the relay to the PLC, and then to the microcomputer board. The data processing capability of the main control board of the elevator has been strengthened. Many large manufacturers have begun to exchange data with interface protocols such as network cable RS235 or BA.RS485, and collect fault signals on the control cabinet. Such as: Thyssen Elevator Company and G-TECH Company cooperated to develop the escalator monitoring system, Hitachi Elevator launched the HERIOS system for factory monitoring. However, specific monitoring of each safety device still requires a large number of wiring harnesses, which are then transmitted through the wired network to transmit real-time data to the Internet. And also need to use a dedicated computer to install related software, and can not be opened to multiple parties. The hardware cost plus the data communication cost also increases the elevator operating cost.
In 2016, the NB-IOT agreement came into effect, NB is a long-distance transmission of narrowband cellular IoT technology and telecom operators bundled operations. This narrow-band feature just meets the needs of elevator remote monitoring. At present, many domestic companies have developed remote monitoring modules that respond to NB technology. The fault code of the control cabinet can be transmitted externally through NB, and can be displayed on any PC or mobile phone terminal. NB technology has greatly promoted the development of the elevator IoT, and the emergence of 5G will promote the upgrade of the smart elevator industry more quickly.
2. What are the advantages of elevator IoT
Elevator is an important travel tool in people's life. It is normal to take the elevator 3-4 times a day. If the elevator you are taking happens to break down, your first reaction is to call the emergency number in the elevator or press the alarm bell. Help? Build an elevator IoT big data platform to realize a variety of alarm methods. If you encounter an elevator failure, in addition to calling the emergency rescue phone in the elevator and pressing the alarm bell for help, you can also alarm through intelligent hardware devices and mobile terminals. The elevator IoT big data platform greatly shortens the rescue time!
2.1 Dynamic monitoring
The key components of the elevator are dynamically monitored. When the system finds that the components are abnormal or close to the service life, the system will automatically send out a warning message to prompt the risk before the failure occurs. Through predictive maintenance, the hidden troubles of failures are eliminated to a large extent, and the failure rate is greatly reduced.
2.2 Remote monitoring
The remote monitoring function is the guarantee of the overall solution. Effective collection, monitoring and management of remote data enables efficient management and control of real-time information and ensures worry-free operation of Giant Cloud 4.0.
2.3 Online maintenance
From the first start of each elevator, an exclusive health file and maintenance diagnosis report are automatically generated. Preset maintenance time, node reminders, real-time recording and feedback of every process when maintenance personnel maintain elevators, to ensure that maintenance work is carried out more punctually, more carefully, and more efficiently.
2.4 Network rescue
Once the elevator fails, it can actively alert the automatic network for precise positioning, find and dispatch the nearest engineer who meets the corresponding technical qualifications, and rush to the scene in time to deal with and troubleshoot in an emergency, so as to provide you with all-round, all-weather safety. Assure.
2.5 Online installation
Carry out all-round control of the installation progress and standardized operation, and firmly grasp the key nodes in the installation process through preset information and node control, so that the elevator installation is more accurate.
3. Why Elevator IoT Will Be Concerned
The purpose of the development of elevator technology is to provide a safer and more comfortable elevator experience. Of course, the Internet of Things for elevators is no exception. The Internet of Things for elevators uses advanced technical means to ensure the safe operation of elevators. The specific advantages are mainly reflected in the following points:
3.1 The elevator IoT has changed the previous reporting process. The elevator operation big data and monitoring data are integrated, so that the elevator supervision department can understand the elevator operation status, failure rate, rescue of trapped people, and elevator maintenance quality. Master first-hand information and avoid inaccurate data caused by information transmission. The elevator IoT provides data support for elevator supervision.
3.2 The Internet of Elevator IoT can realize rescue of trapped people more conveniently. According to the monitored information, the Internet of Elevator IoT can timely send the fault to the elevator rescue mobile phone, monitoring platform, elevator maintenance unit, etc., so as to realize the rapid rescue of trapped people. At the same time, recording the cause of the failure is convenient for maintenance personnel to carry out maintenance in the later period, and improves the efficiency of rapid rescue.
3.3 Now some elevator maintenance companies have malicious competition, which leads to problems such as lax maintenance and inadequate maintenance technology. The elevator IoT can change the traditional elevator monitoring and maintenance mode, and can obtain elevator data anytime, anywhere. Determine whether the elevator maintenance technology is standardized, and improve the quality of elevator maintenance.
3.4 Elevator IoT realizes elevator safety early warning. Elevator manufacturing companies can summarize elevator fault data, operating status parameters, etc. through the analysis data of elevator IoT, providing data support for elevator quality and improving elevator safety performance. Early warning of elevator failures, realizing elevator maintenance on demand, and eliminating possible failures in the bud.
3.5 The elevator IoT can provide value for direct or potential customers. Elevator supervision departments, manufacturers, maintenance units, etc. can obtain the information they need in the big data analysis, and generate economic benefits.
