Abstract

The invention belongs to the technical field of elevator control, and discloses a position detector for an elevator cage. The position detector for an elevator cage comprises an elevator controller and an atmospheric pressure detection and altitude data acquisition communication electronic board, wherein, the electronic board is arranged in the elevator cage and is connected with the elevator controller through a communication cable; and the elevator controller processes a transmission signal from the atmospheric pressure detection and altitude data acquisition communication electronic board so as to judge the position of the elevator cage in a well. The invention further comprises the other atmospheric pressure detection and altitude data acquisition communication electronic board which is fixedly arranged in the well and is connected with the elevator controller through a communication cable, wherein, the elevator controller processes the transmission signals from the two atmospheric pressure detection and altitude data acquisition communication electronic boards so as to judge the position of the elevator cage in the well. The position detector for the elevator cage provides reliable position detection of the elevator cage for elevator control and has low cost, and is convenient to install and simple to operate.

Description

technical field [0001] The invention belongs to the technical field of elevator control, and in particular relates to an elevator car position detection device. Background technique [0002] At present, when the elevator fails or the power supply system stops suddenly, especially after the rescue operation, the elevator will have a wrong floor after it is powered on again. If it runs at a normal high speed at this time, it will cause safety hazards. Therefore, when the existing elevator that does not install the elevator car position detection device is powered on, it will first run to the bottom of the elevator at a lower speed to confirm its position, and then enter the process of running at a normal speed. Yet the floor that elevator is installed is more and more higher at present, if run to the lowest floor station from higher floor at low speed, the required time can be very long, has had a strong impact on the use of elevator. Therefore, there is a need for an effecti...
