Problems solved by technology

[0002] At present, the preferred technology for special vehicles is generally to paste RFID tags on special vehicles, install RFID readers on the road, and transmit RFID readers to the traffic signal control system through the 485 bus. It is time-consuming and labor-intensive, and multiple RFID card readers need to be installed at the intersection. The cost of RFID card readers is relatively high, and to provide power and communication for these devices, it is necessary to slot and lay pipes on the road to pass through various power lines and signal lines. The management and control method of this special vehicle is expensive in terms of hardware cost and installation and maintenance cost, and it is difficult to realize in practical applications

Abstract

The invention discloses a traffic signal machine control method for priority passage of an extraordinary vehicle, which overcomes the flaw of the priority passage of the extraordinary vehicle in the practical application which is difficult to realize. The traffic signal machine control method comprises steps of obtaining the positioning information of the extraordinary vehicle, transmitting vehicle positioning information, receiving the vehicle positioning information, calculating the distance away from an intersection, determining the driving direction of the extraordinary vehicle and switching the green light phase by the signal machine. The invention effectively realizes the priority passage of the extraordinary vehicle based on the GPS positioning technology and the Zigbee transmission technology.

Description

technical field [0001] The invention relates to the technical field of traffic signal lamp control, in particular to a traffic signal control method for special vehicles to pass preferentially. Background technique [0002] At present, the preferred technology for special vehicles is generally to paste RFID tags on special vehicles, install RFID readers on the road, and transmit RFID readers to the traffic signal control system through the 485 bus. It is time-consuming and labor-intensive, and multiple RFID card readers need to be installed at the intersection. The cost of RFID card readers is relatively high, and to provide power and communication for these devices, it is necessary to slot and lay pipes on the road to pass through various power lines and signal lines. The management and control method of this special vehicle is expensive in terms of hardware cost and installation and maintenance cost, and it is difficult to realize in practical applications.
