Abstract

The invention discloses a coal mine ventilator online monitoring and diagnosis device which comprises a rotation speed signal detection unit, a processor, a storage module, a display module and a monitoring and diagnosis upper computer. The processor comprises a data communication module. The rotation speed signal detection unit and the display module are connected with the processor. The processor is connected with the monitoring and diagnosis upper computer through the data communication module. The rotation speed signal detection unit detects rotation speed data of a ventilator and outputs the rotation speed data to the processor. The processor stores the received rotation speed data in the storage module and sends the rotation speed data to the monitoring and diagnosis upper computer. The monitoring and diagnosis upper computer conducts diagnosis according to the rotation speed data and returns a diagnosis result to the processor. The processor receives the diagnosis result and outputs the diagnosis result through the display module. The coal mine ventilator online monitoring and diagnosis device has the advantages of being accurate in diagnosis, convenient to use, instant in detection, flexible in implementation, simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of coal mine safety, in particular to an online monitoring and diagnosis device for a coal mine fan. Background technique [0002] For a long time, the number of gas accidents has occupied a high proportion in the total number of coal mine accidents. Gas is a common harmful gas in coal mines, also called biogas, which is a colorless, odorless, tasteless, flammable and explosive gas. It is usually attached to the coal seam and will be released automatically during the coal seam mining process. When the concentration of gas in the air reaches a certain level, there will be an explosion when there is an open flame, and when the concentration is 9.5%, the explosion is the most powerful and destructive. Gas explosion will generate high temperature, high pressure, shock wave and release toxic gas. In order to reduce and avoid gas accidents, in accordance with the requirements of relevant safety regulations, fans and fan ...
