Part of the Case—— Roadway、Bridge、Tunnel
MRD™子午线®——Application Case in Transportation Industry
MRD™子午线®——Monitoring System Features
1. The system needs to collect the traffic information and status in multi-directions. These information will be used to control the traffic information after being analyzed, processed and judged. Adjust and control the traffic flow in real time;
2. The collection point of monitoring system have dense terminals and large network bandwidth traffic; the popularity of HD video in monitoring system caused the sharp increase in network traffic;
3. The collected information includes the information of HD video monitoring、vehicle section detection、emergency detection、meteorological monitoring;
4. Long distance physical layout of expressway made the huge distance between the primary monitoring center/ public security center and the toll station, and the huge distance between the toll stations.
MRD™子午线®——Demands and Challenges in Monitoring System
1. Terminal equipment with large quantity and variety. Most equipments are equipped with Ethernet interface, but there are also many terminals with serial interface and digital interface;
2. The distance between equipments is far. The distance between neighboring toll stations even can reach to 40~80km. It is a huge challenge to the deployment, connection and maintenance of equipments;
3. Uneven distribution of the monitoring terminal. It needs to deploy many monitoring terminals between the toll stations and their neighborhoods. But the quantity of terminals along the way is relatively less;
4. The power supply may be unstable due to the power supply according to road sections. And the monitoring system of some section may not work because of the power supply problem;
5. Electromechanical facilities are easy to be demolished by humans and be stole. Daily maintenance and management becomes a huge challenge due to the long distance;
