System and method for real-time monitoring of working state of traffic signal facility

Abstract

The invention discloses a system for the real-time monitoring of the working state of the traffic signal facility, and the system is provided with a signal lamp controller. A power supply monitoring sensor group is connected to an input end of the signal lamp controller, a communication module is connected to a communication end, and the communication module is connected with the central controller through a network and a network communication module. The power monitoring sensor group comprises a first power monitoring sensor, a second power monitoring sensor, and a third power monitoring sensor. The first power monitoring sensor is installed near a power lap joint point of the traffic signal facility, the second power monitoring sensor is installed near the output end of the signal lamp controller, and the third power monitoring sensor is installed nearby the control signal input end of a signal light group. Through the setting of the power detection sensor, the system can achieve thesegmented real-time monitoring of the power supply of the signal lamp facility and the electric signal data of a control loop, and enables a fault point to be limited in a smaller range.

Description

technical field [0001] The invention relates to the field of automatic control of traffic signal facilities, in particular to a real-time monitoring system for the working status of traffic signal facilities. Background technique [0002] Most of the existing traffic signal control facilities use electronic circuit technology and integrated circuit technology to realize the generation and cycle control of the control sequence through the single-chip microcomputer. Through the peripheral electronic circuit, the control sequence is converted into AC on-off control, and the cable and the cable The connected signal lamp displays the control sequence on the signal lamp, so that the signal lamp lights up according to the programmable timing and cycle, so as to realize the control of traffic signals; at the same time, the single-chip microcomputer can upload the timing and cycle to the control center through 4G or the network to realize single-chip microcomputer Contact with the ba...

Problems solved by technology

The installation cost is high, and it only has the function of detecting the working status of the signal lights, and cannot judge the fault location and problem, nor has the function of preventing the occurrence of faults, and cannot meet the large-scale and large-scale traffic lights in the current city. The status monitoring, repair and maintenance needs
