The input end of the acquisition channel 3 is connected to the output end of each external finger detection sensor, and the output end of the acquisition channel 3 is connected to the detection signal input end of the regulation circuit 1. The regulation circuit 1 can sequentially input the analog signals output by each external finger detection sensor into the conversion circuit 4 by sequentially turning on the switch circuit 2, and the conversion circuit 4 converts the analog signal into a digital signal and then inputs it into the regulation circuit 1. When a user's finger contacts the corresponding finger detection sensor, the acquisition channel can sequentially transmit the bio-signals detected by each finger detection sensor to the conversion circuit through the on-off control of the switch circuit. The bio-signals detected by the finger detection sensors are all analog signals. The conversion circuit can convert each set of analog signals into a set of digital signals, which are then input into the regulation circuit. This facilitates the regulation circuit to collect data from each finger through each set of digital signals, thereby completing data detection of the human body's physical condition. The detection signal transmission circuit for a traditional Chinese medicine detector disclosed in this embodiment uses a switch circuit to switch the channels of the acquisition circuit to control the transmission of the signals output by each external finger detection sensor to the conversion circuit. The signals output by each external finger detection sensor can be input into the conversion channel as indicated through the channels of the switch circuit.

The conversion circuit not only converts the biosignals detected by each finger detection sensor into digital signals that can be input to the regulation circuit, but also processes each group of biosignals. The filtering module can amplify small biosignals and increase their amplitude, making the difference between the signal and noise more distinct, thereby improving the signal-to-noise ratio and increasing the accuracy of the collected biosignal data.
