Contactless elevator door lock, contactless elevator door lock controller and contactless elevator door lock control method

Abstract

The invention discloses a contactless elevator door lock comprising a fixed lock hook seat, a fixed lock hook, a movable lock hook seat and a movable lock hook. A contactless detecting module used for detecting the position of the movable lock hook and locking pressure of the fixed lock hook and the movable lock hook is arranged on the fixed lock hook seat. A contactless elevator door lock controller comprises an amplifying module, an A / D (analog / digital) conversion module, a circuit detecting module, an MCU (microprogrammed control unit) controller, a CAN (control area network) interface and on-off indicator lamps. A contactless elevator door lock control method includes judging an elevator door lock is locked when a distance sensor and a force sensor are simultaneously effectively triggered, and sending a control signal. The contactless controller is adopted to substitute for an existing contact controller, integral safety performance of the elevator is further improved and completed, and safety accidents caused by door lock breakdown are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a non-contact elevator door lock, an elevator door lock controller and an elevator door lock control method. Background technique [0002] The elevator safety code stipulates that after the door lock is closed, an electrical device is required to verify it. At present, the elevator door locks at home and abroad all adopt the form of contacts. The lock hook closure verification is realized by the method of direct contact with the contacts driven by the mechanical action of the door lock. The door lock contacts are assembled in a relatively closed box. The principle of its control method is as follows Figure 4 shown. There are following potential safety hazards and deficiencies in this door lock: [0003] 1. It is not easy to check the effective contact of the contacts, and it is troublesome to maintain. Especially when the door lock contacts are broken or the cont...
