Segmentation method of equipment operation process

Abstract

The present invention discloses a method for segmenting the running process of equipment, the method comprising: acquiring acceleration data of equipment running in a set direction; and acquiring acceleration of one of the running actions according to the acceleration data collected in the set direction data to form the acceleration data area corresponding to the running action; according to the acceleration data in the acceleration data area of ​​an action, the acceleration data area of ​​an action is divided into several segments; the change speed of the acceleration in the acquisition acceleration data area is lower than the set value The area of ​​is used as a segment area, and a segment node is generated in a segment area; according to the obtained several segment nodes, the area between adjacent segment nodes is regarded as a segment, thereby forming several segments. The segmentation method of the equipment operation process proposed by the present invention can analyze the equipment operation process according to the acceleration data in the equipment operation process, and obtain each stage of the equipment operation and the acceleration data of each stage.

Description

technical field [0001] The invention belongs to the technical field of automation equipment, and relates to an equipment operation analysis method, in particular to a segmentation method for equipment operation process. Background technique [0002] Elevator is the most commonly used vertical transportation vehicle in modern high-rise buildings. It saves people's time and physical strength and provides convenience for daily life. As a special equipment that is closely related to the safety of public life, the safe operation of elevators has attracted more and more attention from the society. However, due to the complex structure of the elevator, it is an urgent need for elevator management, maintenance and safe operation to ensure the safe and reliable operation of the elevator and to detect its operating status and fault conditions. [0003] According to the statistics of China Industry Information Network, at present, China is the world's largest producer and consumer of ...

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
