Problems solved by technology

Although both the ramp turn and the intersection traffic problem have problems such as vehicle steering control, the road in all directions at the intersection is flat, and there is no problem of uphill and downhill; while the ramp turn has problems such as uphill and downhill control and limited sightlines , the traffic control is more complicated, which makes the conventional traffic control method cannot be directly applied

Embodiment 1

[0065] Such as figure 1 with Figure 7As shown, the slope turning traffic command system based on wireless sensor network, it includes two parts: the perception subsystem based on wireless sensor network and the traffic reminder subsystem based on finite state automata, in which the perception subsystem based on wireless sensor network includes The wireless sensor 6 and the wireless transmission module; the wireless transmission module is composed of the cluster head node 5, the wireless transceiver convergence node 4, the computer 2 and the wireless transceiver control sub-node 7, and several wireless sensors 6 and a cluster head node 5 form a cluster 9. The traffic reminder subsystem includes the use of state transition diagrams of finite state automata to aid in the design of control circuits and reminder devices. Several wireless sensors 6 of the same cluster 9 send the detected vehicle information to the cluster head node 5 by radio after preliminary data processing, an...

Abstract

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. In the invention, wireless sensor network is adopted to mainly complete automatic monitoring control reminding to vechile traffic at slope turn.

Description

technical field [0001] The present invention relates to the traffic warning technology for turning on a slope, relates to the communication technology of a wireless sensor network, in particular to a method for using the wireless sensor network in traffic control, so as to solve the traffic control and vehicle scheduling problems of turning on a slope. Background technique [0002] The intelligent traffic command system is a large-scale system that combines advanced information technology, data communication transmission technology, electronic control technology and computer processing technology to make it effectively comprehensively used in transportation services, control and management. Its purpose is to uniformly dispatch pedestrians and vehicles, greatly improve the efficiency of comprehensive transportation, and ensure traffic safety. [0003] The traffic situation on the turn of the ramp is more complicated and the control is more difficult. And turning on a ramp is...
