Anti-unexpected movement elevator control device and method

Abstract

The invention discloses an elevator control device and method for preventing accidental movement, which includes a control circuit module, a door safety circuit module, an elevator main safety circuit module, and a rope clamp for clamping or loosening a wire rope, wherein the The control circuit module includes the electromagnetic coil of the rope clamp, the upward overspeed protection switch, the car door lock switch, and the delay capacitor connected in parallel with the electromagnetic coil of the rope clamp; the door safety circuit module includes the hall door locks of each floor, the car door lock switch, Rope gripper pre-trigger switch, and relay switch; the main safety circuit module of the elevator includes at least the rope gripper action switch and a safety circuit, wherein the rope gripper pre-trigger switch and the rope gripper action switch are related to the mechanical action of the rope gripper couplet. The invention has a one-piece complete structure, strong independence and versatility, high mechanical reliability, no detection circuit, no type test, low cost, and convenient maintenance.

Description

technical field [0001] The invention relates to an elevator control device and method for preventing accidental movement. Background technique [0002] With the development of urban construction and the improvement of people's quality of life, when residents can enjoy good land public transportation services when traveling, they also desire to obtain convenient vertical transportation in their residences. Therefore, in recent years, the number of elevators has grown rapidly, and the number of elevators in the country has increased from 285,000 in 2003 to 3,009,300 in 2013. As a special means of transportation, the elevator is an indispensable means of transportation for ordinary people. It brings unprecedented convenience to people's daily life. The safety and reliability of its operation are issues that many people are generally concerned about. The quality of residential elevators is good. It directly affects the quality of life of ordinary people. In 2014, the General Ad...

AI Technical Summary

Problems solved by technology

The main safety hazards of elevators in use in my country are "car door opening and walking" and "car stalling or falling out of control or falling to the top", and the reasons for these safety hazards are mainly due to the existing elevator control device, which cannot effectively realize Unexpected car movement protection (UCMP)

Although the elevator control devices of some manufacturers can realize the UCMP function, they need to be equipped with a monitoring unit and an execution unit. According to national standards, the monitoring unit needs to be type-tested separately, and the monitoring unit also needs to be equipped with a separate detection device. Matching use, which not only increases the cost of product manufacturing and certification, but also cannot allow the monitoring unit to be used alone, and the application range is narrow
