And the adjusting circuit U3 is connected with the signal converting circuit U2, the adjusting circuit U3 sends an adjusting instruction to the signal converting circuit U2 based on configuration, the signal converting circuit U2 generates a voltage/frequency conversion ratio corresponding to the adjusting instruction based on the received adjusting instruction, and performs voltage/frequency conversion processing on the received signal based on the voltage/frequency conversion ratio.
As an example of the present embodiment, the signal conversion apparatus may include: the controller (which may be, for example, a micro-control unit, and the type of the controller is not limited in this embodiment of the present disclosure), the on-off control circuit U1 may include a relay, and the controller may be connected to the relay, and a user may operate the controller through, for example, an operation panel (for example, the operation panel may be a keyboard or a touch display screen) connected to the controller to generate and send a first control instruction to the relay, where the relay forms an on-off mode corresponding to the first control instruction, for example, as shown in fig. 1, and the user may use a digital processing board (an example of the controller, not shown in the figure) to control a change in output level of the signal mcu_io1 (an example of the first control instruction) to drive on or off of the relay, so as to implement a simulation of a fault scenario of signal on or signal off.

The signal conversion circuit U2 may be connected to the on-off control circuit U1, and the signal conversion circuit U2 may perform voltage/frequency conversion processing on the received frequency signal based on the current voltage/frequency conversion ratio and output the converted frequency signal.
