1.1 Project background
The frequent traffic accidents of muck trucks are distressing. Every year, many people unconsciously bury themselves under the muck wheels. While investigating the responsibility of the accident, should we use a rational mind to examine the current situation of domestic muck truck management.
1.2 RFID management and construction planning of slag trucks
1.2.1 Introduction to Management System
The system comprehensively uses RFID (radio frequency) technology, GPS positioning technology, Beidou positioning technology, image recognition technology, data encryption technology, multi-sensor information fusion technology, computer and network technology and other international and domestic leading technical means, with each vehicle The installed RFID electronic tags and traditional license plates are the information sources, the system management platform and the data server are the operating centers, combined with the vehicle and vehicle owner information database and regular data updates, through the handheld inspection system, on-board inspection system, and fixed inspection carried by law enforcement officers The three inspection methods of the system provide immediate voice and digital display alarms when abnormal situations are found, and upload the inspection information to the system management platform in time to form a dynamic, three-dimensional, rigorous, and accurate intelligent automated traffic supervision and inspection network to enable transportation The driving route and time of slag trucks and special vehicles are more standardized, which can greatly reduce the cost of traffic inspection, improve the efficiency of inspection, and realize targeted and humanized civilized traffic supervision.
1.2.2 System Architecture Planning
Slag trucks and special vehicles have certain particularities in the process of participating in road traffic. For example, the route of their participation in road traffic has strict requirements and restrictions on time, and involves many departments such as environmental protection and public security. Using RFID electronic license plate or RFID electronic identity authentication technology, combined with GPS or Beidou positioning technology, the vehicle’s driving route and driving time are audited, verified and supervised.
The system uses a variety of inspection methods to implement vehicle filing, driver filing, operating line filing, and operating time filing on slag trucks (special vehicles). The vehicle operating line is collected in real time through the inspection equipment, and the vehicle operating time is compared with the filing data. The system automatically inspects, and personnel conduct on-site inspections on slag trucks (special vehicles) to participate in road traffic inspections.
1.2.3 On-board inspection system
The vehicle inspection system consists of three parts: image recognition system, radio frequency signal receiving system and data processing system. The on-board inspection system is installed in the traffic law enforcement vehicle. Law enforcement officers can drive traffic law enforcement vehicles to conduct vehicle inspections anywhere within the jurisdiction. It integrates dynamic image recognition technology and RFID radio frequency identification technology. It uses image recognition of physical license plates and vehicle characteristics and remote radio frequency identification of RFID anti-counterfeiting ceiling lights. The physical feature information and electronic information of the vehicle are compared, and the problematic vehicle is found, and the voice and digital display alarm will be issued immediately to prompt the law enforcement personnel to intercept; the system can perform dynamic inspections on vehicles traveling in the same direction or reverse direction at a speed of 60 kilometers per hour while stopping. It is also possible to track and inspect the moving vehicles while it is moving, and to inspect the parked vehicles.
1.2.4 Handheld inspection system
The hand-held inspection system is a portable inspection device equipped for law enforcement personnel, which is mainly used for the inspection of slow-moving or parked vehicles. When law enforcement officers point the receiving antenna of the handheld inspection system at a suspicious vehicle, if the information displayed by the system matches the physical characteristics of the vehicle, it is a legitimate vehicle. If the system cannot receive electronic information or the received electronic information and physical characteristics If it does not match, the system will immediately issue an alarm prompt, and then it can be determined that the vehicle is an illegal vehicle or a problem vehicle; at the same time, the handheld inspection system can also be set to wirelessly connect to the nearby fixed inspection system. When the fixed inspection system finds a problem vehicle, it will immediately report The handheld inspection system alarms and displays the vehicle information; the working distance of the handheld inspection system is within 20 meters.
1.2.5 Fixed audit system
The fixed inspection system consists of four parts: an image recognition system, a radio frequency signal receiving system, a data processing system, and a wireless or wired transmission system.
Fixed inspection systems are generally installed at specific points such as traffic guards or toll stations. The system automatically monitors vehicles passing the inspection range. When illegal vehicles or problem vehicles are found and identified, the system will automatically call the police and provide information about the vehicle. It was quickly uploaded to the management platform and the nearby handheld inspection system, and the law enforcement officers found the illegal vehicle or the problematic vehicle in a timely manner based on the alarm information.
1.3 Project construction advantages and technical characteristics
