Abstract

The invention discloses a traffic light control system based on a PLC. A data acquisition module comprises a road acquisition unit and a school acquisition unit. A data positioning module is used for obtaining and analyzing the running coordinates of a vehicle on a road to obtain coordinate analysis information; A data analysis module is used for receiving driving information and the school attending and school-over information, analyzing the driving information to obtain driving analysis information, analyzing the school attending and school-over information to obtain school attending and school-over information analysis information, and combining the driving analysis information and the school attending and school-over information analysis information to obtain data analysis information; A data processing module is used to receive and process the data analysis information to obtain data processing information; An adjustment control module is used for dynamically adjusting and controlling the operation of a signal lamp according to the data processing information; the method aims to solve the problem that traffic lights cannot be dynamically adjusted according to the driving state of the road and the school attending and school-over information states of students, and the problem that the brightness duration of the 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...
