Problems solved by technology
In actual situations, the control quantity is often more important than the monitoring quantity. Even if it is known that the power equipment or environmental parameters have exceeded their normal range during operation, if the operating state of the equipment cannot be changed by effective means, then there is no fault handling at all. possibility, the monitoring of equipment often becomes an empty decoration
For example, if the duty officer finds that the ambient temperature of a base station is too high during the duty process, he can solve the problem by controlling the opening and closing of the air conditioner or lowering the temperature setting point of the air conditio

Abstract
The invention discloses a power distribution cabinet monitoring system and a method. The system comprises a fault detection module, an intelligent fire protection module and a main control platform. The fault detection module is used for real-time data monitoring and fault analysis for a power distribution cabinet, the main control center is used for receiving the fault information of a power device, according to the fault position, an alarm module A is started to control the intelligent fire protection module to start an alarm unit B and a fire protection control unit, the execution mechanism at the field of the power distribution cabinet is controlled to control the automatic regulation of the temperature and the humidity at the internal portion of the power distribution cabinet, on-off of the loop power supply of the power distribution cabinet and the automatic switch-on of the fire protection device are controlled. The multi-level fault analysis and monitoring from the operation condition of the power equipment to the microenvironment of the cabinet and the like are achieved, and multiple detection modes are set through multi-level fault early warning and flexible threshold values, so that potential crisis can be timely found, and meanwhile, the power supply of the power device in the power distribution cabinet can be controlled to be switched on and off and the fire protection device can be controlled to be switched on and off according to the fault warning, so that the bidirectional development of monitoring quantity and control quantity is balanced.
Description
technical field [0001] The present disclosure relates to a power distribution cabinet detection system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The traditional power distribution cabinet monitoring system focuses on the monitoring of the overall environment of the power distribution cabinet, while ignoring the internal monitoring of the power equipment in the power distribution cabinet. The overall temperature and humidity are kept within an appropriate range. The temperature parameter values at various points in the computer room are different. The temperature value of the air outlet of the air conditioner cannot explain the overall temperature of the computer room and the microenvironment temperature of the cabinet. The normal operation of the air conditioner cannot indicate that the equipment is Normal operation, ...
