Elevator door opening and closing time accurate acquisition system

Abstract

The invention discloses an elevator door opening and closing time accurate acquisition system, comprising an acceleration data acquisition module, a tentative area acquisition module, and a real area acquisition module; the acceleration data acquisition module is used to acquire the acceleration data of the elevator door running in the door opening and closing direction; The tentative area acquisition module is used to obtain the tentative acceleration data area of ​​the elevator door opening and closing action according to the acceleration data collected in the set direction, and determine the start and end points of the action; the real area acquisition module is used to collect all the temporary acceleration data. In the fixed door opening and closing areas, areas that overlap or are too close in time are merged to obtain the real elevator door opening and closing area. The precise acquisition system for elevator door opening and closing time proposed by the present invention can acquire the precise time for elevator door opening and closing.

Description

Technical field[0001]The present invention belongs to the technical field of automation equipment, and is related to an elevator device, and more particularly to an elevator switch gate time accurate acquisition system.Background technique[0002]The elevator is the most commonly used vertical transport vehicle in modern high-rise buildings. It saves people's time and physical strength, providing convenience for daily life. As a special equipment closely related to public life, its safe operation is increasingly received by society. However, due to the complex elevator structure, it is necessary to ensure safe and reliable operation of the elevator, and detect the urgent needs of the operating state and failure to become an elevator management, maintenance, and safe operation.[0003]According to China's industrial information network statistics, at present, China is the world's largest elevator into origin and consumer, and is also the largest elevator exporter. In 2017, my country add...

AI Technical Summary

Problems solved by technology

[0007] a. The real-time elevator operation information collected by the system is transmitted through wireless communication networks such as China Mobile, China Unicom or China Telecom, so the data flow is quite large. In addition, the wireless network operator charges according to the traffic, so that the operation of this elevator remote monitoring system High cost, unable to achieve 24-hour uninterrupted monitoring

[0008] b. Simple functions, no database management function, only simple elevator operation status monitoring, no maintenance and quality management monitoring function, no early warning of elevator failure

[0009] c. The system compatibility is poor, and it can only be deployed and controlled for a small number of elevator types, and cannot accurately analyze and judge elevator faults, and cannot accurately give the specific fault location of the elevator

[0010] Existing monitoring methods are usually through the camera installed in the elevator, or by receiving the alarm signal sent in the elevator to understand the situation in the elevator; it is impossible to predict the elevator failure
