Application of Embedded IPC in Expressway Monitoring System
The purpose of the highway monitoring system is to ensure traffic safety and smooth roads, provide reliable networked traffic services for rapid transportation, provide free communication channel services for traffic flow/vehicle-road interaction, and provide full-time responsive emergency services for emergency events. , to provide travelers with refined and autonomous travel services.
1. System overview
Using visual technology and image recognition technology, the highway monitoring system can accurately locate the road vehicle target, track the running track of the vehicle, intelligently judge the driving path of the vehicle, and realize the comprehensive information monitoring of the vehicle. At the same time, it realizes functions such as traffic violation detection and recording, vehicle intelligent monitoring, traffic incident detection, traffic parameter detection, and video surveillance.
2. System requirements
The highway monitoring system requires the functions of automatic detection and recording of traffic violations, vehicle feature recognition, video monitoring, data storage, data transmission, and self-diagnosis and alarm. In addition, the highway monitoring system requires uninterrupted and long-term stable operation in complex environments such as outdoor high temperature/low temperature, humidity, electromagnetic, dust, and vibration. It is required that the industrial computer adopts a low-power, fanless design, with a mean time between failures > 30,000 hours and an average repair time < 1 hour; supports ultra-high-definition cameras with a wide detection range; built-in large-capacity storage, no need for additional video equipment; Diagnosis and alarm function, convenient for later maintenance; support software upgrade mode to ensure the improvement of subsequent functions.
3. System framework and schematic diagram
The highway monitoring system can be divided into traffic monitoring, collection, analysis and release of traffic information and meteorological information. Among them, the camera cooperates with the industrial computer to automatically patrol various traffic conditions within 1km, and on the other hand, it is responsible for receiving the alarm signals of various punching vehicles from the monitoring center at any time, and automatically tracking. In addition to the normal monitoring tasks, the industrial computer also needs to transmit monitoring information to the monitoring room in real time.
