Problems solved by technology

The consumption is large, and maintenance is required on a regular or irregular basis, which increases the workload of the maintenance personnel accordingly. At the same time, it also puts forward higher requirements for the technical level of the maintenance personnel. The traditional mining sensor detection requires a variety of instruments, tools, and tooling. Work together, including multimeter, DC regulated power supply, frequency meter, ammeter, wires, etc. The use and conversion of various instruments makes maintenance a space-consuming and time-consuming task

Embodiment Construction

[0008] Such as figure 1 As shown, the sensor fault detection device has a power module, and the alternating current is converted into direct current through the power module to supply power for each part of the whole device. The frequency display module detects and displays the analog signal output function of the mine sensor. The function of the mA current display module is to detect and display the output function of the mA current signal of the mine transmission switch sensor. The frequency signal input module and the current signal input module can judge whether the signal output interface of the mine sensor is normal. The power output module supplies power to the mine sensor to be detected, and at the same time displays the current working parameters of the mine sensor through the working voltage / working current display module. The working voltage / working current display module is connected with an alarm.

[0009] Wherein, the frequency signal input module adopts a sta...

Abstract

The invention discloses a sensor fault detection device and relates to the technical field of sensor fault diagnosis. The sensor fault detection device comprises a power supply module, wherein one end of the power supply module is connected with 220V alternating current, and the alternating current is converted into direct current through the power supply module to be respectively supplied for a frequency display module, a milliampere current display module and a working voltage / working current display module; the frequency display module is connected with a frequency signal input module; the milliampere current display module is connected with a current signal input module; the working voltage / working current display module is connected with a power supply output module and an alarm. The sensor fault detection device has the advantage that on the premise of not changing a traditional mine sensor fault maintenance mode, and various commonly-used instruments, tools and tooling are integrated, so that convenience in maintaining a portable instrument is realized.

Description

technical field [0001] The invention relates to the technical field of sensor fault diagnosis, in particular to a sensor fault detection device. Background technique [0002] Mine sensors are an essential part of the "Coal Mine Safety Monitoring System" that coal mines must be equipped with. The consumption is large, and maintenance is required on a regular or irregular basis, which increases the workload of the maintenance personnel accordingly. At the same time, it also puts forward higher requirements for the technical level of the maintenance personnel. The traditional mining sensor detection requires a variety of instruments, tools, and tooling. Work together, including multimeter, DC regulated power supply, frequency meter, ammeter, wires, etc. The use and conversion of various instruments makes maintenance a space-consuming and time-consuming work. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the pre...
