Claim 3:
4. The method of claim 1, wherein after detecting whether the voltage value of the power supply signal matches the standard voltage value corresponding to the function module, the method further comprises:
responsive to the voltage value of the power supply signal matching the standard voltage value corresponding to the function module, adjusting an output voltage of an amplifier corresponding to the function module, wherein the amplifier is configured to output the power supply signal;
detecting whether the power supply signal received by the function module changes with adjustment of the amplifier; and
responsive to the power supply signal received by the function module changing, determining that the connection error does not occur in the power supply connection of the function module; and responsive to the power supply signal received by the function module not changing, determining that the connection error occurs in the power supply connection of the function module.
