For ease of understanding the present embodiment, control is changed to a kind of signal disclosed in the utility model embodiment first
Device processed describes in detail.
Embodiment one：
Fig. 1 shows the structure diagram for the signal conversion control device that the utility model embodiment provides.Such as Fig. 1 institutes
Show, the signal conversion control device include processor 10, switching switch 20, the first power interface 30, second source interface 40 and
Signaling interface 50.
Wherein, switching switch 20 can be relay or electronic switch, in the present embodiment using relay, the relay
The model of device can be, but not limited to as G6K-2P-Y-12, it will be appreciated that the relay of switching control function can be realized in this reality
With in new protection domain.
Processor 10 is connected with the control terminal of switching switch 20, which receives input information, and according to the input
Information transmits switching command to the control terminal of switching switch 20.Specifically, it is to be inputted by user by input equipment to input information
, which includes at least instrument model to be tested.Processor 10 is found and the instrument type according to the instrument model
The supply voltage of number associated storage, corresponding switching command is generated to the control terminal of switching switch 20 according to the supply voltage.
The input terminal of switching switch 20 is connected with the first power interface 30 or second source interface 40, and switching switch 20 connects
