Monitoring system and method for power distribution cabinet

Abstract

The invention discloses a monitoring system of a power distribution cabinet. The monitoring system comprises a PLC control module. The PLC control module is electrically connected with a power supplymodule, a detection module and an adjustment module, and is used for controlling start and stop of the work of the power supply module, receiving and processing a signal transmitted by the detection module, and controlling start and stop of the work of the adjustment module. The system provided by the invention can monitor the environment of various occasions, can provide some powerful monitoringdata, can give an alarm and caution under an abnormal condition to jointly maintain the safety of a factory or home environment, and can monitor power, smoke and other environments to jointly maintaina safe and reliable environment. When the power distribution cabinet runs to a low power threshold or a threshold lower than the low power threshold, a lock command is issued to turn off the power supply of the power distribution cabinet. The influence of virtual power is avoided, and a user can know whether the power distribution cabinet has power.

Description

technical field [0001] The invention belongs to the technical field of monitoring a power distribution cabinet, and in particular relates to a monitoring system for a power distribution cabinet, and also relates to a monitoring method for a power distribution cabinet. Background technique [0002] The power distribution cabinet is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. In order to improve the safety of the power distribution cabinet in the prior art, a comprehensive protection system is basically added in the cabinet to realize alarm processing when there are problems such as insufficient power, equipment fire, and excessive temperature in the circuit. [0003] The invention patent with the notification number CN103138389A discloses an intelligent power distribution cabinet. An intelligent module is installed in the power distribution cabinet. The intelligent module is composed of a syn...

[0003] The invention patent with the notification number CN103138389A discloses an intelligent power distribution cabinet. An intelligent module is installed in the power distribution cabinet. The intelligent module is composed of a synchronous current detection circuit, a synchronous voltage detection circuit, a digital microprocessor DSP Composed with a control circuit, the synchronous current detection circuit and the synchronous voltage detection circuit transmit the detected current signal and voltage signal to the digital microprocessor DSP in real time, and the digital microprocessor DSP judges and sends a control command to the control circuit, and the control circuit according to the command To deal with it, the above-mentioned patent has an intelligent module installed in the power distribution cabinet, which can eliminate the faults in the power distribution cabinet by itself, but the intelligent module is not connected to the external equipment, the loop detection data cannot transmit the positioning information to the outside, and the management personnel cannot timely and effectively Accurately grasp the operating status of the power distribution cabinet, which greatly reduces the safety of the power distribution cabinet, and the accuracy of data acceptance by the intelligent module is poor, which is easy to cause misjudgment when analyzing the data
