Problems solved by technology
Among them, the influence of the structural parameters of the sensor itself on the signal of the sensor can be eliminated by optimizing the structural parameters, while the influence of the surrounding environment on the signal of the sensor is currently mainly corrected by the standard value of manual real-time detection to correct the sensitivity parameters of the sensor. There will be correction errors caused by human error, and the efficiency is not high, which will increase the workload of sensor users

The invention provides a sensor signal drift automatic tracking correction method and a related device, and the method comprises the steps: firstly determining a first average detection current of a to-be-corrected sensor in a first preset time period with a correction starting moment as a starting moment; then determining a second average detection current of the to-be-corrected sensor in a second preset time period taking the current moment as the termination moment; obtaining a drift factor coefficient at the current moment according to the first average detection current and the second average detection current; and correcting the sensitivity parameter of the to-be-corrected sensor based on the drift factor coefficient so as to realize automatic tracking and correction of signal drift of the to-be-corrected sensor, thereby avoiding correction errors caused by manual misoperation, improving the correction efficiency of the signal drift, and reducing the workload of a sensor user.
Description
technical field [0001] The present disclosure relates to the technical field of sensor signal correction, in particular to a method for automatic tracking and correction of sensor signal drift and related devices. Background technique [0002] Sensor signal drift refers to the phenomenon that the output of the sensor changes with time under the condition of constant input. There are two main reasons for the drift: one is the influence of the sensor's own structural parameters on the sensor's signal; the other is the influence of the surrounding environment (such as temperature, humidity, etc.) on the sensor's signal. Among them, the influence of the sensor's own structural parameters on the sensor's signal can be eliminated by optimizing the structural parameters, and the influence of the surrounding environment on the sensor's signal is currently mainly corrected by the standard value of manual real-time detection to correct the sensor's sensitivity parameters. Correction ...
