Description
Technical field
The present invention relates to vehicle positioning system control circuit field, particularly a kind of vehicle positioning system based on RFID technique
System circuit.
Background technology
Dangerous material have the characteristics such as blast, inflammable, murder by poisoning, burn into radioactivity, in transport, handling and storage management process
The especially protection of middle needs.With economic development social progress, the safety problem of hazardous materials transportation has obtained higher and higher attention.
Simultaneously coordinate port area management requirement, it is necessary to hazardous materials transportation vehicles while passing port area, travel route, port area residence time, disobey
Rule monitoring, emergency processing etc. are managed collectively.
The purpose for implementing bayonet socket pass through management system is to realize in garden that enterprise self-determining declares vehicle pass-through plan, and according to
Enterprise's handling capacity is limited the quantity pass through in limited time, and then the purpose of management and control is carried out to entering area's vehicle.Management system primarily to
Solve enterprise periphery working truck to be unloaded in economic zone arbitrarily park, road occupying violating the regulations, traffic safety hidden danger the problems such as, main mesh
Mark is to strengthen the management to entering garden haulage vehicle, gathers associated vehicle information, and the work for routine safety supervision provides base
Plinth is supported.

Defeated supervision and management, traffic accidents emergency management and rescue and processing commander for the national games provide trackability information, can be that government is responsible for
Department provides basic big data by informationization technology.
Hazardous materials transportation vehicle management, it is related to the safety of vehicle and goods, is related to the safety of port area owner, to danger
The real-time, effectively management of product haulage vehicle, the whole port area safe class for being related to dangerous material will be greatly improved, improve management effect
Rate, and actively promote the scientific and technological level and efficiency of such management.The system integrating RFID technology, wireless communication technique, big data
The advanced technical concept such as technology realizes technology with really effective and feasible.
Conventional art for RFID technique with being based only on single technology carrier, it is attached before technology for realizing
Component, realize that the concrete operations after technology are realized by other independent equipment, poor compatibility, the information of each technical equipment
Individually storage, it is unfavorable for integrating statistics, inaccurate coordination.
