Abstract

The invention discloses a PLC-based traffic light control system. The data acquisition module includes a road acquisition unit and a school acquisition unit; the data positioning module is used to obtain and analyze the running coordinates of driving on the road to obtain coordinate analysis information; the data analysis The module is used to receive driving information and school commute information, analyze the driving information to obtain driving analysis information, analyze commute to school information to obtain commute to school analysis information, and combine the driving analysis information and commute to school analysis information to obtain data analysis information; use The data processing module receives and processes the data analysis information to obtain the data processing information; the adjustment control module is used to process the information according to the data and dynamically regulate the operation of the signal lights; The problem of dynamic adjustment of lights, and the problem that the brightness of traffic lights cannot be reasonably arranged.

Description

technical field [0001] The invention relates to the technical field of controllers, in particular to a PLC-based traffic light control system. Background technique [0002] The full name of PLC is programmable logic controller, which is a digital operation electronic system specially designed for application in industrial environments. It uses a programmable memory to store instructions for performing logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production through digital or analog input and output. process. [0003] Publication number CN109243187A discloses a traffic light control system. The traffic light control system includes a control unit and a passing road discriminator connected with the control unit, a road flow detector, an intersection detector and a traffic light group. Judging the road in the direction of traffic where the traffic light shows a green light, the road flow...
