System and method for controlling intelligent traffic signal lamp based on power line carrier

Abstract

The invention provides a system and a method for controlling an intelligent traffic signal lamp based on a power line carrier, and belongs to the field traffic control. When the system runs, a vehicle triggers an induction signal when passing through two stages of underground pressure sensors with different distances from an intersection, the signal is transmitted to an intelligent monitor host through a power supply circuit of equipment; and the intelligent monitor host is used for analyzing the traffic flow situation, adjusting the delay time of the red lamp in other lanes according to the signal, and controlling start and close of a passenger baffle according to the display state of the signal lamp. Meanwhile, the intelligent monitor host is used for transmitting the traffic flow data to the Internet via a wireless router, a mobile phone terminal and a computer terminal are connected with the Internet to receive data, and field monitor and mandatory control can be selectively realized. The system can be used for monitoring the number of vehicles at the junction so that a duty computer, a duty mobile phone and other equipment can be used for remotely monitoring and controlling signal lamps at the junction, body safety of staff and driving safety of vehicles can be guaranteed, and occurrence of serious consequences can be avoided.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to an intelligent traffic signal light control system and control method based on a power carrier. Background technique [0002] The current traffic light systems are almost always equipped with wireless sensor devices or signal lines to transmit signals to control the passage of vehicles, so there are the following shortcomings: [0003] (1) When the traffic flow in the two directions of the intersection is very different, in the case that no vehicles pass horizontally or all vehicles have passed, the vehicles coming in the vertical direction have to wait for the red light, causing a lot of energy loss and air pollution; Intelligent regulation. [0004] (2) The fixed adjustment method of red and green time is not perfect, which cannot effectively deal with the congestion of vehicles during peak hours; [0005] (3) The pedestrian passage facilities at the zebra crossing at the inter...

AI Technical Summary

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
