Enhance anti-interference ability by utilizing the rationality of input quantity and calculation results. Action commands are only issued when the controller input quantity is within a reasonable range; When the input bus voltage is too high or too low, the controller will lock; When the input current is too low, the controller is also locked. For example, in the process of analog sampling and calculation, errors may also occur due to interference,

A verification step can be added to the software design of the device, which means that after the calculation is completed, the data window is moved by one sampling value and then the calculation is carried out. The result should be very close to the first calculation. If the difference is significant, the third calculation should be carried out, and the calculation result with little difference should be taken as the correct value. This method can eliminate errors caused by interference in data sampling and computation.
