The third terminal of the first relay 211 receives a second control signal, which can control the connection or disconnection between the first and second terminals of the first relay 211, or in other words, close or open. Furthermore, the connection or disconnection between the first and second terminals of the first relay 211 enables the connection or disconnection between the other end of the power supply circuit and the other end of the first load 310. Thus, through the first relay 211, the connection or disconnection between the other end of the power supply circuit and the other end of the first load 310 can be controlled, achieving circuit control between the other end of the power supply circuit and the other end of the first load 310.

[0059] Furthermore, the first relay 211 enables electrical isolation between the other end of the power supply circuit and the other end of the first load 310, improving the safety and stability of the circuit. The first relay 211 can achieve a switching function by connecting to both the other end of the power supply circuit and the other end of the first load 310 via a port connection, eliminating mechanical wear issues, enabling stable operation for extended periods, and completing signal transmission, processing, and response in a very short time, achieving high-precision detection and improving detection accuracy.
