Slope turn traffic command system based on wireless sensor network

The invention relates to a slope turn traffic command system based on wireless sensor network. The system is composed of a perception subsystem based on wireless sensor network and a traffic reminding subsystem; the perception subsystem comprises a sensor module and a wireless transmission module; the wireless transmission module comprises a wireless transceiving converging node, a cluster-head node and a wireless control subnode; the sensor module is connected with the cluster-head node and mounted on the face and two sides of the slope turn road; the wireless control subnode is connected on the traffic reminding equipment arranged at two sides of the road; the wireless transceiving converging node is connected with a remote control computer; the traffic reminding subsystem comprises a control circuit based on a finite state automat, a speed limitation board and a tweeter; the control circuit receives command from the wireless control subnode to control the speed limitation board and the tweeter.
