Intelligent traffic signal controller with remote control function

Abstract

The invention discloses an intelligent traffic signal controller with a remote control function. The intelligent traffic signal controller comprises a master control unit mounted in a signal controller cabinet and a power source for supplying power. The master control unit comprises a mainboard and a processor arranged on the mainboard. A clock unit is arranged in the processor, and the processor is connected with a data collecting unit, a car video detecting unit, a traffic signal lamp control unit, a memorizer and an alarm through a communication interface of the processor. The data collecting unit comprises a water level sensor, a spark sensor, a temperature sensor and a signal controller fault detecting circuit. A communication interface comprises a first wireless communication unit, and the processor is in wireless connection with the remote control unit through the first wireless communication unit. The intelligent traffic signal controller has excellent cost performance, and is simple in structure, convenient to implement, high in integration degree and small in running power consumption, system expansion and system configuration are standard, the workload and work difficulty of maintenance are reduced, maintenance can be carried out in an electronic mode, operation is very convenient, and system reliability is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a signal machine. Background technique [0002] With the development of society, traffic problems, especially urban traffic problems, have become an important factor in economic and social development, so traffic signals are an indispensable tool for traffic control in contemporary society. The traffic signal machine is specifically used as a device on the actuator in the control system. It is mainly installed near each intersection, and the signal green light time is changed in real time according to the detected traffic flow data. Most of the current traffic signal systems have the disadvantages of large size, low reliability, high energy consumption, and irregular expansion and configuration of the system. Moreover, when the signal machine cabinet is abnormally pried open, flooded in rainy weather, abnormal humidity inside the cabinet, fire occu...
