[0066] Based on the first embodiment, check figure 2 , figure 2 It is a schematic flow chart of the first embodiment of the sensor temperature correction method of the present invention, including:

[0067] Step S10, after the air conditioner stops running or when the air conditioner is just powered on, obtain the temperature value detected by each temperature sensor of the air conditioner;

[0068] Obtain the current temperature value of the temperature sensor that may have temperature offset in the current air conditioner, such as the exhaust sensor, heat exchanger tube temperature sensor, ambient temperature sensor, radiator temperature sensor, etc. The prerequisite is that the temperature sensor is not an electric heating sensor. Since there are multiple temperature sensors in the air conditioner that may have temperature offsets, there are also multiple acquired corresponding current temperature values. The number of the temperature sensors is related to the model and...

Abstract

The invention discloses a sensor temperature correction method. The sensor temperature correction method comprises the steps that after an air conditioner stops operating or when the air conditioner is just powered up, temperature numerical values detected by temperature sensors of the air conditioner are obtained; the temperature sensors which detect the temperature values with first difference values being smaller than a preset threshold value serve as the normal temperature sensors, and a base temperature value is calculated according to the temperature values detected by the normal temperature sensors; and when second difference values between the temperature values detected by the abnormal temperature sensors and the base temperature value are larger than or equal to the first preset temperature value, the abnormal temperature sensors are corrected according to the second difference values. The invention further discloses a sensor temperature correction device and a computer-readable storage medium. Temperature correction of the temperature sensors in the air conditioner is achieved, the temperature measuring values of the temperature sensors keep normal, and thus the air conditioner error caused by the mistaken temperature measuring values is avoided.

Description

technical field [0001] The invention relates to the field of air conditioning control, in particular to a sensor temperature correction method, device and a computer-readable storage medium. Background technique [0002] When the air conditioner is in use, multiple temperatures are used for temperature collection. The collected temperature is used as the basis for air conditioner control, and the accuracy of the sensor plays a vital role in the reliable operation of the air conditioner. After the temperature sensor is used for a period of time, the temperature may drift, resulting in inaccurate temperature monitoring and affecting the operation of the air conditioner. The traditional inspection method can only monitor the short-circuit or open-circuit fault of the sensor, but if the sensor does not have a short-circuit or open-circuit fault, but only a temperature offset, the traditional method cannot judge and prompt the user to replace the sensor, which may cause the unit...
