Running state detecting device of elevator

Abstract

The invention relates to a running state detecting device of an elevator, which solves the problems of unstable running state detection, great construction difficulty, and the like of the traditional elevator. The device comprises a concave body, a built-in circuit board and a control loop, wherein the concave body is matched with an elevator well magnetic insulating plate. The concave body is a U-shaped seal cavity comprising a base and two vertical seats; the base is provided with internal thread holes; two pairs of infrared transmitting pipes and infrared receiving pipes which are packagedin vertical seat cavities are fixed in transmitting holes and receiving holes of the vertical seats; the center connecting line direction of the two kinds of pipes is parallel to the concave body along the running direction of the magnetic insulating plate; and the side for fixing the infrared receiving pipes is provided with a reed pipe. The invention has reasonable design, simple structure and small volume, can realize interference resistant signal modulating detection, ensure a stable detecting state and accurate data and be matched with the magnetic insulating plate, is convenient for field installation and debugging, can rapidly and instantaneously detect the position, speed and direction of the elevator independent of an elevator control system and has the function of floor positioncorrection.

Description

technical field [0001] The present invention relates to a detection device for elevator door zone, position and end station (speed change) signal, especially a kind of detection device which cooperates with existing elevator shaft magnetic isolation board and can realize real-time monitoring elevator independent of elevator control system The position and speed elevator running state detection device is mainly used in elevator leveling and terminal station signal detection, elevator voice station announcement, elevator monitoring and other places that require elevator position and speed detection. Background technique [0002] At present, elevators have become an indispensable means of vertical transportation for high-rise buildings. The number of new elevators in the world is about 500,000 each year, and the number of elevators in China alone reaches 1.3 million, and it is growing at a rate of 20% per year. In the elevator control system, the rotary encoder is indispensabl...
