Communication device, voltage detection method, and computer-readable storage medium

A voltage detection method, comprising:

• controlling a voltage sampling circuit to collect voltages output by a power supply or by a first voltage conversion circuit of a communication device in a plurality of sending timeslots or a plurality of receiving timeslots of the communication device, wherein the communication device comprises one or more voltage conversion circuits coupled to the power supply of the communication device, and the voltage sampling circuit is coupled to at least one of:
• the power supply or an output end of at least one of the one or more voltage conversion circuits;
• determining a real voltage of the power supply based on the voltages output by the power supply or by the first voltage conversion circuit in the plurality of sending timeslots or the plurality of receiving timeslots of the communication device;
• and
• before controlling the voltage sampling circuit to collect the voltages output by the power supply or the first voltage conversion circuit in the plurality of sending timeslots or the plurality of receiving timeslots of the communication device, controlling a switching circuit to connect the voltage sampling circuit to the power supply or the first voltage conversion circuit, wherein the switching circuit is configured to selectively connect the voltage sampling circuit to the power supply or the first voltage conversion circuit.
