Abstract

The invention discloses a sensor fault identification method and a storage medium. The method comprises the following steps: receiving data collected by a sensor in real time, and determining time characteristics and / or regional characteristics of the data collected by the sensor according to the time and / or place of the data collected by the sensor; selecting a historical data value range corresponding to the time characteristics and / or the regional characteristics from a sensor historical database; judging whether the data collected by the sensor is within the historical data value range ornot; if so, judging that the sensor has no fault, and if not, judging that the sensor has a suspected fault; and further judging whether the suspected fault sensor fails according to auxiliary verification data associated with the suspected fault sensor. By further judging whether the suspected fault sensor fails or not according to the auxiliary verification data associated with the suspected fault sensor, misjudgment of the fault of the sensor is prevented.

Description

technical field [0001] The invention belongs to the technical field of sensor data processing, and in particular relates to a sensor fault identification method and a storage medium. Background technique [0002] With the improvement of people's living standards, the intelligentization of home has become an important direction of future home development. The intelligence of the home is inseparable from various sensors, such as temperature sensors, photoelectric sensors, raindrop sensors, photoelectric sensors, flooding sensors, smoke sensors, combustible gas sensors, door and window sensors, raindrop sensors, humidity sensors, human sensors and Sound sensors and more. [0003] For the smart home control system, the sensor is equivalent to the human senses. If the sensor fails, it will provide the control system with wrong information and cause wrong control. Therefore, the detection of sensor failure is particularly important. [0004] However, the current sensor is direc...
