High-reliability intelligent traffic instrument with function of remote control

Abstract

The invention discloses a high-reliability intelligent traffic signal instrument with a function of remote control, and the traffic signal instrument comprises a main control unit disposed in a signal instrument cabinet, and a power supply for supplying power. The main control unit comprises a mainboard and a processor disposed on the mainboard. The interior of the processor is provided with a clock unit, and the processor is connected with a data collection unit, a vehicle video detection unit, a traffic signal lamp control unit, a storage unit and an alarm through a communication interface. The data collection unit comprises a water level sensor, a flame sensor, a temperature sensor, and a lamp filament integrity detection module. The communication interface comprises a first wireless communication unit, and the processor is in wireless connection with a remote controller through the first wireless communication unit. The signal instrument is excellent in cost performance, is simple in structure, is high in integration degree, is small in power consumption during operation, is more standard in system extension and system configuration, reduces the workload of maintenance and work difficulty, can achieve maintenance in an electronic mode, is very convenient to operate, and greatly improves the system reliability.

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, high bit error rate of the signal remote control circuit, and irregular system expansion and configuration. Moreover, when the signal machine cabinet is abnormally pried open, flooded in rainy weath...
