Project Introduction
Zhejiang Provincial Party Committee Secretary Zhao Hongzhu, Governor Lu Zushan, Hangzhou Municipal Party Committee Secretary Huang Kunming and other leaders respectively visited the 52nd Research Institute of China Electronics Technology Group Corporation to inspect and guide the development of the Internet of Things industry.
In December 2009, the People’s Government of Zhejiang Province and the People’s Government of Hangzhou City respectively signed a strategic cooperation framework agreement with China Electronics Technology Group Corporation, unanimously agreeing to establish a long-term and stable strategic partnership, and make full use of China Electronics Technology Group Corporation’s strong scientific research and production capabilities. Promote independent innovation and industrial transformation and upgrading in Zhejiang Province and Hangzhou City. The Hangzhou Municipal People’s Government and China Electronics Technology Group Corporation have carried out a lot of preliminary preparation and project determination around the construction of the Internet of Things demonstration project. Among them, the Hangzhou Municipal Elevator Operation Safety IoT System, led by the Hangzhou Bureau of Quality and Technical Supervision and implemented by the 52nd Institute, will be the first to start as a demonstration project for government public services.
introduction
The safety IoT system for elevator operation in Hangzhou uses front-end sensing, embedded control, video and audio codec, 3G wireless transmission, massive video storage, data fusion, emergency linkage and other technical means to control elevator fault parameters, video, audio, and temperature. Sensing, humidity sensing and other information are comprehensively processed through the Haikang Elevator Gateway, and then transmitted through the two-way transmission of the sensor network, 3G or broadband, and the safety status of tens of thousands of elevators and the surrounding environment information are incorporated into a unified Elevator operation safety IOT system management platform, realizes fault early warning, remote monitoring of fault process, voice comfort of trapped people, real-time linkage with corresponding functional departments, elevator maintenance units and elevator manufacturers, and strengthens the supervision of elevator manufacturers and maintenance units And management, speed up the handling of elevator faults, and improve the efficiency of saving people.
The system has successfully achieved the first time to grasp information, issue instructions, implement rescue at the first time, investigate and process at the first time, analyze the elevator quality and elevator maintenance quality digitally, and realize the digitization, networking, and safety management of elevator operation. Intelligent.
System advantages
1. Information immediacy
When the elevator is trapped, four “first times” are realized, namely, grasping information at the first time, issuing instructions at the first time, implementing rescue at the first time, and investigating and processing at the first time.
2. Technical advancement
It forms a closed loop of information from the perspectives of perception, transmission, processing, and feedback, and adopts a series of advanced technologies such as Internet of Things technology, digital video and audio monitoring technology, 3G technology, and embedded technology. The core technology has independent intellectual property rights.
The system optimizes the special environment of wireless network video transmission, thereby adjusting the network transmission protocol, optimizing the video coding scheme, and automatically adjusting the code stream and image quality of the video image according to the change of the network bandwidth.
It can realize 3G, short-distance wireless communication, broadband, dedicated line and other transmission methods, and 3G is compatible with 2G networks at the same time.
Meet the transformation needs of various existing systems, so that the system can not lag behind in the next few years, and achieve online upgrades.
3. Data security
The system software platform, combined with the design ideas of operators for many years, fully realizes the functions of system anti-intrusion and data leakage prevention.
Sensor technology is used to collect elevator fault parameters and abnormal alarm information, but it does not affect the elevator’s own control system to ensure elevator safety.
4. Economical
The system will only transmit the video data through the network when it receives the elevator trapped fault alarm, which saves a lot of network bandwidth resources, effectively reduces data transmission traffic, and reduces system operating costs.
The system uses wireless firewall penetration technology, active connection mode for network connection, penetration firewall obstacles, and saving money.
The system can combine the elevator management system that the user has built or is under construction, and on the basis of meeting existing requirements, it supports the scalability of system functions, thereby protecting user investment and avoiding repeated investment.
5. Operational practicability
Realize the hierarchical management of cities, counties and districts, data information can be synchronized or authority management according to requirements, and the platform is more expandable and manageable.
Elevator fault type management, analysis and judgment of trapped people, find out the commonality and personality of trapped elevators, improve the ability to prevent elevator faults, reduce the frequency of elevator faults, and help elevator quality and elevator maintenance. Supervise and manage to realize the digitization, networking and intelligence of elevator operation safety management.
Start different emergency plans according to the set rules, which is convenient for actual operation.
6. Anti-harsh environment design
Combining with 52 years of product anti-harsh environment technology accumulation, the system is designed for the special environment of elevator car and elevator machine room to ensure product reliability and meet electromagnetic compatibility requirements.
7. Adopt big platform software
To manage multiple brands, multiple specifications, and tens of thousands of elevators, large platform software is needed. The central platform deploys an integrated elevator fault management platform, including database service modules, management service modules, access service modules, alarm service modules, streaming media service modules, Storage management service module, Web service module, etc., complete the interaction of various data information, integrating management, exchange, processing, storage and forwarding.
