technical field

The invention relates to the field of elevator monitoring devices in the special equipment industry, in particular to a monitoring device and a monitoring method for artificial unlocking of elevator landing doors.

Background technique

Manual unlocking refers to various situations in which the landing door is opened with a triangular key, the landing door is opened with needle-nose pliers, the landing door is opened with tweezers, or the landing door is opened with two household keys. In normal leveling, the car door knife drives the landing door to open the door.

Unlocking refers to opening the emergency unlocking device of the elevator landing door.

The emergency unlocking device is very important as a necessary device for the rescue of elevator failures and other situations. However, accidents caused by the use of triangular keys to open the emergency unlocking device often occur, especially when non-professionals open the landing door, resulting in falling or falling accidents. In the absence of floor monitoring, it is very difficult to analyze the accident caused by the artificial opening of the landing door or the elevator itself, and it is even impossible to analyze the real cause of the accident, resulting in an indeterminate accident.

In response to the above problems, the patent application No. 201120458950.0, titled Elevator Floor Door Status Monitoring Device, discloses a method to monitor the floor doors of each floor by detecting the closed state of the door lock switch on the floor door lock, and determine which floor If there is a problem with the landing door, the purpose is to enable the maintenance personnel to quickly diagnose and deal with the elevator landing door fault. At the same time, the faulty elevator can be diagnosed through remote monitoring, so as to improve work efficiency and reduce labor costs. The closed state of the elevator door lock is monitored by electric shock, which is suitable for quickly finding out the problem of the floor door of the faulty floor after the elevator failure occurs, and cannot prevent and monitor the accident caused by artificial unlocking.

The Chinese Patent No. 201220356852.0 discloses a quick identification system for elevator faulty door locks, including car door lock switches and door lock contactors on each floor of the elevator to form a series circuit, and each car door lock switch on the series circuit. The address sub-modules are respectively connected to the address sub-modules through the power signal acquisition line, and each address sub-module is connected to the address main module through 485 module transmission. The system uses the address sub-module to determine which layer of door locks are faulty, which improves the efficiency of maintenance. The patent only discloses the identification of faulty door locks, and cannot judge and give early warning of whether the artificial unlocking is normal, nor can it be used as identification evidence for the artificial opening of the landing door at the unmonitored floor, resulting in a fall or a fall accident.

Through the analysis of the current situation of elevator landing door safety, the applicant intends to develop a monitoring device and monitoring method for artificial unlocking of elevator landing doors, and intends to achieve the following objectives:
