The processor 11 is electrically connected to the positive connection detection module 12. The positive detection module 12 includes a first detection submodule 121 and a first transistor 122, and the first detection submodule 121 is configured to detect that the positive electrode CAR + and the negative electrode CAR-receive an electrical signal. When the first detection submodule 121 detects that the positive electrode CAR + is connected to a positive signal and the negative electrode CAR-is connected to a negative signal, a positive power-on signal is generated. The first detection submodule 121 sends the positive electrical signal to the processor 11 through the first transistor 122, so that the processor 11 enters a normal operation state.

It should be noted that, in this embodiment, the device to be started 2 is an electronic device with a battery capable of starting, such as a battery car. The processor 11 is a chip with arithmetic capability. Normally, the electric signals received by the positive electrode CAR + and the negative electrode CAR-are provided by a power supply device, such as a battery, other than the starting system 1, that is, the power supply device provides a positive electric signal and a negative electric signal.
