Car and car door monitoring algorithm

Abstract

The invention discloses a car and car door monitoring algorithm which comprises the following steps: S1, acquiring acceleration data of a car door in the horizontal direction and the vertical direction through a motion sensor mounted on the car door of an elevator; S2, obtaining an acceleration curve by adopting a leader mean algorithm according to the collected car door acceleration data; and S3,working out a speed curve and a distance curve according to the acceleration curve. According to the car and car door monitoring algorithm, independent monitoring and calculation are achieved, the car and car door monitoring algorithm is not affected by elevator faults, elevator operation is not disturbed, and higher safety is achieved. One sensor is adopted to monitor the running states of a carand the car door at the same time, and the structure is simpler. The car and car door monitoring algorithm is simple, and complex algorithms such as Kalman filtering are not needed, so that high-costcomputing equipment such as an industrial computer is not needed. The car and car door monitoring algorithm is different from a traditional mean value algorithm, the mean value is not obtained in a segmented mode, and data size loss cannot be caused. The operation is reversible, and the original value can be reversely deduced at any time according to the result for other applications.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a monitoring algorithm for a car and a car door. Background technique [0002] At present, although domestic elevators have realized automatic control, most of them do not have the function of remote transmission of operating data, and elevator manufacturers are unwilling to open operating data and interfaces. Various elevator maintenance units and testing agencies cannot obtain real-time data and data of elevators. The real-time status of the elevator. The elevator cannot be monitored in real time, only regular maintenance and testing can be carried out. [0003] Due to the lack of continuous data support, the maintenance content is not targeted, and accidental failures often occur in elevators that have just been maintained or passed the inspection, and even cause accidents and personal injuries; and some elevators are still in good condition. Manpower and material resource...

[0002] At present, although domestic elevators have realized automatic control, most of them do not have the function of remote transmission of operating data, and elevator manufacturers are unwilling to open operating data and interfaces. Various elevator maintenance units and testing agencies cannot obtain real-time data and data of elevators. The real-time status of the elevator

The elevator cannot be monitored in real time, only regular maintenance and testing can be carried out

[0003] Due to the lack of continuous data support, the maintenance content is not targeted, and accidental failures often occur in elevators that have just been maintained or passed the inspection, and even cause accidents and personal injuries; and some elevators are still in good condition. Manpower and material resources make it impossible to realize on-demand maintenance and on-demand inspection

[0004] The algorithms of elevator data collection and alarm inventions that appear now are extremely complex, and require a lot of sensor data. Some need to be equipped with industrial computers for calculation, and some need multiple sets of sensors.
