An intelligent traffic signal light control system and control method based on power carrier

Abstract

The present invention is an intelligent traffic light control system and method based on electric power carrier, which belongs to the field of traffic control. When the system is running, when the vehicle passes two levels of buried pressure sensors with different distances from the intersection, the induction signal is triggered, and the signal passes through the power supply line of the equipment. Send to the intelligent monitoring host, the intelligent monitoring host analyzes the traffic flow, and adjusts the delay time of the red lights of other lanes according to the signal, and controls the start and close of the pedestrian baffle according to the display status of the signal light. At the same time, the intelligent monitoring host transmits the traffic flow data to the Internet through the wireless router, and the mobile terminal and the computer terminal receive data through the Internet connection, and can choose to realize on-site monitoring and mandatory control. The invention can intelligently monitor the state of the number of vehicles at the intersection, and equipment such as on-duty computers and mobile phones on duty can remotely monitor and control the state of signal lights at the intersection in real time, ensuring personal safety of personnel and driving safety of vehicles, and avoiding serious consequences.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a power carrier-based intelligent traffic signal light control system and control method. Background technique [0002] The current traffic signal light systems are almost all equipped with wireless sensing devices or arranged signal lines to transmit signals to control the passage of vehicles, so there are the following disadvantages: [0003] (1) When there is a big difference in the traffic flow in the two directions of the intersection, in the case of no vehicles passing in the horizontal direction or all the vehicles have passed, the vehicles coming in the vertical direction have to wait for the red light, resulting in a large amount of energy loss and air pollution; Intelligent regulation. [0004] (2) The fixed adjustment method of red and green time is not perfect, and it cannot effectively deal with vehicle congestion during peak hours; the disadvantages of waiting for gr...

Problems solved by technology

[0003] (1) When there is a big difference in the traffic flow in the two directions of the intersection, in the case of no vehicles passing in the horizontal direction or all the vehicles have passed, the vehicles coming in the vertical direction have to wait for the red light, resulting in a large amount of energy loss and air pollution; Intelligent regulation

[0004] (2) The fixed adjustment method of red and green time is not perfect, and it cannot effectively deal with vehicle congestion during peak hours; the disadvantages of waiting for green lights when there are few vehicles during low peak hours

[0005] (3) The pedestrian passage facilities at the zebra crossing at the intersection are not perfect, and the protection effect on pedestrians is poor;

[0006] (4) In the existing traffic signal light system, the small car behind is easily blocked by the big car in front of the traffic signal light information, and the error of running a red light is large

[0007] (5) On-site temporary control relative personnel position is fixed, inconvenient for on-site command
