AI Technical Summary

Technical Problem

The existing technology is difficult to realize real-time automatic verification of the accuracy of the sensors when the different start-up combinations of the cold supply season, including only turning on a single cold machine, resulting in the inability to maintain efficient operation in the long term and increase operational energy consumption.

Method used

By collecting the operating data of the cold station BMS system, pre-processing is performed using data filtering analysis algorithm, dividing the operating condition interval, establishing a multivariate regression model, monitoring the deviation between the sensor readings and the predicted values ​​of the reference model in real time, performing adaptive filtering correction and benchmark model updates to achieve sensor accuracy verification.

Benefits of technology

It realizes the accuracy of the entire cold station system and each cold station sensor when different start-up combinations are enabled during the cold supply season, including only turning on a single cold station, so that the cold station BMS system can maintain efficient operation for a long time and reduce operating energy consumption.

Abstract

The invention discloses a sensor self-checking method and device, electronic equipment and a storage medium, and the method achieves the real-time monitoring of the temperature and flow of a cold station BMS system through the additional installation of a temperature sensor and a flow sensor in the cold station BMS system, and achieves the real-time checking of the sensor through the combination of energy conservation and mass conservation. Through the proposed control logic, the sensors are enabled to realize checking of the accuracy of the whole cold station system and the accuracy of each cold machine sensor in different start-up combinations in the cold supply season, including the condition that only a single cold machine is started, so that the cold station BMS system is enabled to maintain efficient operation for a long time, and the operation energy consumption is reduced. Therefore, the defects that an existing sensor fault diagnosis technology is high in cost, large in difficulty, poor in real-time performance and adaptability and the like are overcome, and the problem that sensor fault diagnosis cannot achieve the expected effect is solved.
