Elevator sensor self-calibration system and method

Abstract

The invention discloses an elevator sensor self-calibration system. An elevator control mainboard and a measuring module are included; the measuring module comprises a sensor and a processor; the elevator control mainboard is used for sending a measuring instruction to the processor; the sensor is used for acquiring static data of an elevator and transmitting the static data to the processor; andthe processor is used for receiving the measuring instruction sent by the elevator control mainboard, controls the sensor to acquire the static data of the elevator and processes the static data, andthe self-calibration process is completed according to the static data acquired by the sensor. The invention further discloses an elevator sensor self-calibration method. By adopting the processor toprocess the static data of the elevator acquired by the sensor and complete the self-calibration process, static errors are eliminated, it is achieved that the sensor is calibrated in real time, the calibrating operation is easy and fast, the function expansibility is high, and cost is low.

Description

technical field [0001] The invention relates to the technical field of elevators, and particularly designs an elevator sensor self-calibration system and method. Background technique [0002] The sensors used in elevators are sensitive components, and the signals are easily affected by random interference. At the same time, in daily use, due to the uneven load distribution in the car, the car may have a certain degree of inclination relative to the horizontal plane. This inclination will cause the sensor installed in the car to introduce measurement errors. Once an error is introduced into the measurement result of the sensor, it will not only affect the measurement accuracy, but also will bring a large accumulated error in the subsequent analysis and operation process, which will have a great impact on the sensor data analysis. Therefore, in order to reduce this type of error situation, the sensor must be calibrated for the reference value deviation before the measurement ...

Problems solved by technology

However, this method needs to be carried out during elevator maintenance, which is also not real-time, and requires human assistance, which is time-consuming and labor-intensive.
