Failure alarm device for coordinated operation of passenger elevator and method based on inductive combined parameter

Abstract

The invention discloses an alarm device for coordinated operation failure of a passenger elevator and a method based on inductive combined parameter. A first permanent magnet and a second permanent magnet are arranged at two door closing portions at the lower corners of lift car doors respectively, a first conductive wire coil is installed at a car sill at the lower edge of the closing center joint of the two doors, and two independent sub-coils with equal number of turns are arranged inside the first conductive coil; a second conductive coil is installed at a car toe guard right below the closing center joint of the two doors; and according to the position of the second conductive coil, a third permanent magnet and a fourth permanent magnet are installed right above the portion, close to the second conductive coil, of the landing door toe guard and right below the portion, close to the second conductive coil, of the landing door toe guard respectively. According to the alarm device, a value is obtained according to the cutting of the permanent magnets and the conductive coils; when the value exceeds a standard normal value, an alarm is given out; and when the alarm occurs, people in the elevator can take the protection measures in time, so that the elevator accidents are reduced, and the personal safety is guaranteed.

Description

technical field [0001] The invention relates to a safety fault detection device for passenger elevators, in particular to a detection method and device capable of detecting problems in the operation of passenger elevators. Background technique [0002] With the development of the economy, the utilization rate of elevators is getting higher and higher. Not only in shopping malls, but also in many floors. Elevators are originally composed of electromechanical and mechanical parts, and the structure is relatively complicated. An important part of safe operation, such as the elevator car door cannot be opened during the elevator operation; when the elevator is leveling, during the process of people entering and leaving, or the car door is not completely closed, the elevator is also prohibited from running. However, when the door operator system runs for a long time, it is likely to lose coordination with other systems, and the above-mentioned abnormal operation problems are seri...
