Embodiment Construction

[0009] The present invention will be further described below in conjunction with accompanying drawing.

[0010] Such as figure 1 As shown, the switch cabinet alarm device includes N status monitoring units, small switches, signal conversion circuits, MCU control units, sound and light alarm circuits and operating status display circuits. The N state monitoring units and signal conversion circuits are respectively connected to the small switch through an Ethernet network; the signal conversion circuit, sound and light alarm circuit and operating state display circuit are respectively connected to the MCU control unit through an I / O interface connect. The small switch is selected from one of Huawei, Cisco or TP-Link series switches, and the MCU control unit is selected from one of AVR, 51 or PIC series chips. The specific working process of the switchgear alarm device of the present invention is as follows:

[0011] Assume that the alarm device requires the environmental alar...

Abstract

The invention relates to an alarming device, in particular to a switch cabinet alarming device which comprises N state monitoring units, a small switch, a signal conversion circuit, a microprogrammed control unit (MCU), a sound-light alarming circuit and an operation state displaying circuit. The N state monitoring units and the signal conversion circuit are respectively connected with the small switch through an Ethernet network. The signal conversion circuit, the sound-light alarming circuit and the operation state displaying circuit are respectively connected with the MCU through input / output (I / O) interfaces. The switch cabinet alarming device has the advantages that information of the state monitoring units distributed at everywhere is collected, so that the state monitoring unit giving out alarm can be quickly locked when the alarm is given out, and the alarm can be eliminated as soon as possible to enable the whole alarming device to work normally.

Description

technical field [0001] The present invention relates to an alarm device, more specifically, relates to a switch cabinet alarm device. Background technique [0002] The switchgear is a kind of equipment with the functions of closing and breaking power lines and protecting the safety of the system. It mainly includes transformers, circuit breakers, fuses and other components. These devices are greatly affected by the external environment, so it is necessary to Monitoring the environmental conditions around the switchgear is of great significance to the safe work of the switchgear. In recent years, accidents caused by insulation problems of switch cabinets have occurred frequently. The main factors causing insulation problems are the temperature and humidity of the environment. Experiments have shown that the insulation resistance and absorption ratio of insulating media decrease with the rise of temperature, so for us A temperature monitoring module is added to the monitoring...
