An illuminator fault monitoring device

Abstract

The invention relates to an illuminator failure monitoring device which comprises a microprocessor, a power source, a control module, a signal acquiring module and a communication circuit. The control module consists of a control circuit and a relay connected with the same; and the signal acquiring module consists of a current-limiting resistor, a photoelectric coupler, a diode and a current transformer. The operation principle of the illuminator failure monitoring device includes that frequency signals can be monitored by monitoring pins of the microprocessor when an illuminator runs normally, so that whether the illuminator is in failure or not can be judged. Compared with the prior art, the illuminator failure monitoring device has the advantages that functions of illuminator failure monitoring and data communication are added so that automatic monitoring and remote alarming of failure of the illuminator are realized, energy economization, real-time failure alarming, high work efficiency and low maintenance cost are achieved, and intellectualization degree of monitoring for the illuminator is increased.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a lighting device fault monitoring device. Background technique [0002] In recent years, with the growth of the economy, my country's urban lighting technology and scale have developed rapidly, but the following two traditional methods have been used in the monitoring of illuminator failures. 1. Organize special personnel to conduct regular manual inspections along the line. Manually determine the fault point; 2. According to the ratio of the current power consumption (the sum of the power consumption of the luminaires in normal working state) to the total power consumption (the sum of the total power consumption of the luminaires), the number of fault points can be estimated, but the fault cannot be determined point. [0003] The disadvantages of the above illuminator fault monitoring method are: high power consumption, low work efficiency, high maintenance cost, it is difficult for the ma...

[0002] In recent years, with the growth of the economy, my country's urban lighting technology and scale have developed rapidly, but the following two traditional methods have been used in the monitoring of illuminator failures. 1. Organize special personnel to conduct regular manual inspections along the line. Manually determine the fault point; 2. According to the ratio of the current power consumption (the sum of the power consumption of the luminaires in normal working state) to the total power consumption (the sum of the total power consumption of the luminaires), the number of fault points can be estimated, but the fault cannot be determined point

[0003] The disadvantages of the above illuminator fault monitoring method are: high power consumption, low work efficiency, high maintenance cost, it is difficult for the maintenance personnel to find the illuminator fault at the first time; even if the fault is found, the type of fault cannot be quickly determined ( Such as illuminator failure, lighting controller failure or power supply line failure, etc.), often affect people's night travel safety due to untimely maintenance, and it is impossible to realize the "point-to-point" direct monitoring of illuminators by the control center
