1. Project background
With the rapid development of society and economy, the number of concrete mixer trucks is showing a rapid growth trend. The overloading, overspeeding and other reasons have caused many traffic accidents, which brought hidden dangers to traffic safety, and also caused losses to enterprises, which seriously affected the harmonious city. Construction process.
In order to strengthen the management of concrete mixer trucks, the Hangzhou Municipal Construction Committee decided to adopt advanced information technology to standardize the transportation of concrete mixer trucks, strictly prevent overloading and overspeeding behaviors of concrete mixer trucks, and improve the driving safety factor, thereby strengthening the supervision of overloading and overspeeding of concrete mixer trucks. .
The 52nd Research Institute of China Electronics Technology Group Corporation used many years of research and development and project practical experience, adopted the technology architecture of the Internet of Things, based on the satellite positioning system, and integrated communication control, computer network, intelligent management and other technologies to develop a concrete mixer truck Overload and overspeed monitoring and management system. After the trial operation of the system, the effect was remarkable. The overload rate of concrete mixer trucks in the main urban area of Hangzhou dropped from 20% to 0.5%, and the number of accidents was also reduced by half.
2. Application field
This system can be applied to concrete mixer trucks, engineering trucks, dangerous goods trucks and other fields.
3. Project history
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, China Electronics Technology Group Corporation successively signed strategic cooperation agreements with Zhejiang Provincial People’s Government and Hangzhou Municipal People’s Government.
In May 2010, led by the Hangzhou Municipal Construction Committee, the Overload and Overspeed Monitoring and Management System for Concrete Mixing Trucks developed by the 52nd Research Institute of China Electric Power Technology Co., Ltd. was launched as a demonstration project of the Internet of Things.
In September 2010, the 52nd Research Institute of China Electric Power Technology Co., Ltd. completed the development of the monitoring and management system for concrete mixer truck overload and overspeed. The system entered trial operation. During the trial operation, the overload and overspeed rate of concrete mixer truck dropped significantly.
From October to November 2010, the project passed technical acceptance and project acceptance successively, and the entire system was well received by experts.
In December 2010, Hangzhou Deputy Mayor Shen Jian visited the commercial concrete management station to observe the overload and overspeed monitoring and management system of concrete mixer trucks and fully affirmed the system.
Four, system principle
Five, system function
1. Real-time collection of loading data. Customize the collection client for each concrete company, and directly collect loading records from the industrial computer database to ensure the authenticity and reliability of the data; if the communication is abnormal and the data cannot be uploaded normally, the data is automatically stored in In the local database, continue uploading after the communication is normal.
2. Real-time collection of speeding information. The GPS system collects real-time information such as the speed and location of the vehicle, and tracks the vehicle’s trajectory in real time; the central server analyzes the vehicle’s violation type according to GPS information: instantaneous speeding, long-term speeding, etc., and counts the start of speeding Time, speed peak and other information.
3. Alarm linkage When the vehicle is overloaded or overspeed, the central server parses out the violation information and sends the relevant information in the form of short messages to the enterprise, management branch, law enforcement traffic police and other relevant personnel.
4. The basic data management system realizes the addition, deletion, modification, and checking of basic data such as management branches, enterprises, and vehicles.
5. Various forms of statistical reports include the company’s daily reports, monthly reports, reports for specified time periods, and statistical reports for vehicles and management branches, so that management departments and enterprises can conduct inquiries, statistics, and analysis of operating conditions.
Six, system characteristics
Seven, system advantages
1. Adopt the hierarchical structure of the Internet of Things to achieve clear hierarchical processing in accordance with the structure of front-end collection, network transmission, central processing and feedback, clear design and easy maintenance.
2. System deployment is flexible, protocol opening adopts common interface protocols, easy to understand and secondary development; server deployment can be flexibly expanded according to system pressure.
3. The system design has good scalability and is easy to customize. The design is long-term, and multiple interfaces are reserved to facilitate the development of users’ value-added services. 4. The system is stable, safe and reliable. The software is designed to be efficient, safe and capable of long-term stable operation; the hardware adopts firewall technology and UPS power supply to fundamentally ensure the stable and reliable operation of the system.
