Problems solved by technology

The landing door lock contact was artificially shorted, the aging of the electrical circuit caused the electrical safety circuit to be short-circuited to the ground, and the user did not know much about the elevator system and the elevator system did not have an effective warning system. These are the main reasons for the above accidents.

Abstract

The invention discloses an elevator landing door lock contact state detecting device and method. The elevator landing door lock contact state detecting device comprises a controller, a sensor and a voltage measuring device, wherein the sensor and the voltage measuring device are connected with the controller. Neither does elevator state information need to be obtained from an elevator control system, nor the elevator control system need to be intervened. The states of elevator door lock contacts and the state of a landing door are comprehensively and accurately known through detecting signals of the sensor and the elevator measuring device, so that misjudgment or false alarm is effectively prevented.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a device and method for detecting the contact state of an elevator landing door lock contact. Background technique [0002] There are endless news about elevator trapping and elevator injury accidents. According to industry data, in 2015, there were 38 accidents in the elevator use link, and 20 accidents in the elevator installation, transformation, repair and maintenance links. Among the causes of accidents, there were 39 accidents caused by equipment failures such as safety accessories or protection devices, and 13 accidents caused by violations of regulations or improper operations, most of which were caused by door lock circuit failures, accounting for about 70%. In recent years, injury accidents caused by accidental or forced opening of elevator landing doors have also occurred from time to time. The landing door lock contact was artificially shorted, the aging of the electrical c...
