1. Project Background
With the rapid development of society and economy, the number of concrete mixer trucks is showing a trend of rapid growth. Its overloading, overspeeding and other reasons have caused many traffic accidents, bringing hidden dangers to traffic safety, and also causing losses to enterprises, seriously affecting the harmonious city. construction process.
In order to strengthen the management of concrete mixer trucks, Hangzhou Municipal Construction Committee decided to adopt advanced information technology to regulate the transportation of concrete mixer trucks, strictly prevent overloading and speeding of concrete mixer trucks, and improve the driving safety factor, thereby strengthening the supervision of overloading and speeding of concrete mixer trucks. .
The 52nd Research Institute of China Electronics Technology Group Corporation has used many years of experience in R&D and project practice, adopted the Internet of Things technology framework, 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 this system, the effect is remarkable. The overload rate of concrete mixer trucks in the main urban area of Hangzhou has dropped from 20% to 0.5%, and the number of accidents has also been reduced by half.
2. Application areas
This system can be used in concrete mixer trucks, engineering transport vehicles, dangerous goods transport vehicles and other fields.
3. Project History
Zhao Hongzhu, Secretary of Zhejiang Provincial Party Committee, Lv Zushan, Governor of Zhejiang Province, Huang Kunming, Secretary of Hangzhou Municipal Party Committee 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 signed a strategic cooperation agreement with the Zhejiang Provincial People’s Government and the Hangzhou Municipal People’s Government.
In May 2010, the overload and overspeed monitoring and management system for concrete mixer trucks developed by the 52nd Research Institute of China Electric Power Science and Technology Co., Ltd. led by the Hangzhou Construction Committee was launched as a demonstration project of the Internet of Things.
In September 2010, the 52nd Research Institute of China Electric Power Co., Ltd. completed the development of the monitoring and management system for the overload and overspeed of the concrete mixer.
From October to November 2010, the project passed technical acceptance and project acceptance successively, and the whole system was well received by experts.
In December 2010, Shen Jian, vice mayor of Hangzhou, 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.
4. System principle
5. System function
1. Real-time collection of loading data The collection client is tailored for each concrete enterprise, and the loading records are directly collected 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 will be automatically stored in the In the local database, continue uploading after the communication is normal.
2. Real-time collection of speeding information The GPS system collects the speed, position and other information of the vehicle in real time, and tracks the running track of the vehicle in real time; the central server analyzes the type of violation of the vehicle according to the GPS information: instantaneous speeding, long-term speeding, etc., and counts the start of speeding Time, speed peak, etc.
3. Alarm linkage When the vehicle is overloaded or speeding, the central server parses out the illegal information, and sends the relevant information to the relevant personnel such as the enterprise, the management branch, the law enforcement traffic police and other relevant personnel in the form of text messages.
4. The basic data management system realizes the operation of adding, deleting, modifying and checking the basic data of management branches, enterprises, vehicles and so on.
5. Various forms of statistical reports include daily reports, monthly reports, reports of specified time periods, and statistical reports based on vehicles and management branches, so that management departments and enterprises can inquire, count and analyze the operation status.
6. System Features
Seven, system advantages
1. Adopt the layered structure of the Internet of Things to achieve clear hierarchical processing according to the structure of front-end collection, network transmission, central processing and feedback, with clear design and easy maintenance.
2. Flexible system deployment, open protocol adopts common interface protocol, easy to understand and secondary development; flexible expansion of server deployment according to system pressure.
3. The system design has good scalability and is easy to customize. The design is long-term in consideration, and multiple interfaces are reserved to facilitate the development of user value-added services. 4. The system runs stably, safely and reliably. The software design is efficient and safe, and can run stably for a long time; the hardware adopts firewall technology and UPS power supply, which fundamentally guarantees the stable and reliable operation of the system.
