The multichannel monitoring system comprises an MCU, a DAC sharing circuit, an ADC sharing circuit, a multi-array switch and at least two sensor probes. Wherein the at least two sensor probes are usedfor collecting physical sign data of a testee. The MCU controls the DAC sharing circuit to drive the monitoring of the single sensor probe, and controls the ADC sharing circuit to receive the monitoring result of the single sensor probe at the same time. And the MCU is also internally provided with a logic control time sequence, so that the multi-array switch sequentially switches on one of the at least two sensor probes for monitoring, and the DAC sharing circuit and the ADC sharing circuit also act on one sensor probe each time under the guidance of the multi-array switch. The multi-channelmonitoring system can cope with the monitoring work of a plurality of sensor probes at the same time, provides more accurate monitoring results under the condition of facing complex application scenes and monitoring requireme
