1. An abnormality detection method, comprising:
shielding all channels in an I2C (Inter-Integrated Circuit) multiplexer, and detecting an I2C controller by using a CPLD (Complex Programmable logic device) to obtain a first detection result;
when the first detection result is that the I2C controller is normal, controlling the I2C controller to detect the I2C multiplexer to obtain a second detection result;
when the second detection result is that the I2C multiplexer is normal, opening the channels, and controlling the I2C controller to detect an I2C slave device connected to each channel to obtain a third detection result;
when the third detection result is that the I2C slave device is normal, exiting detection;
when there is an abnormal result in the first detection result, the second detection result and the third detection result, outputting an alarm information corresponding to the abnormal result.
