Abstract

The invention discloses an air door opening and closing sensing device with an acousto-optic alarm function and relates to the field of coal mine safety monitoring system detection. By the adoption of the air door opening and closing sensing device with the acousto-optic alarm function, the function that when two air doors are opened simultaneously, an acousto-optic alarm signal is given out can be achieved. The air door opening and closing sensing device is mainly composed of two air door sensors. A monitoring substation or signal transmission equipment is connected with the air door sensors through four-core cables. Each air door sensor is composed of a sensing head unit and a magnetic block, wherein the sensing head unit comprises a reed pipe, a relay connected with the reed pipe, and an acousto-optic alarm circuit connected with the relay; the sensing head unit and the magnetic block are installed in the corresponding positions of a door frame of the corresponding air door and the edge of the air door separately; when the air door is closed, the reed pipe gets close to the magnetic block; and when the air door is opened, the reed pipe gets away from the magnetic block. The air door opening and closing sensing device is sensitive, reliable and low in manufacturing cost, cost is reduced, and the air door opening and closing sensing device can still give an alarm when transmission of other monitoring systems is failed.

Description

technical field [0001] The invention relates to the detection field of a coal mine safety monitoring system, in particular to a damper switch sensing device, which continuously monitors the "open" or "closed" state of a damper in a mine. Background technique [0002] The damper switch sensing device is a device for continuously monitoring the "open" or "closed" state of the damper in the mine in the coal mine safety monitoring system. The conventional air door switch sensing device is composed of two parts, the sensing head group and the magnetic block. The sensor head group is composed of reed switch casing, plug, socket cable fixing plate, etc., and the magnetic block group is composed of magnet, casing, etc. It installs the sensing head group with the dry reed switch and the magnetic block that generates a strong magnetic field on the door frame of the damper and the edge of the door respectively. When the damper is closed, the magnetic block is close to the switch asse...
