Count resets are carried out to the timing in timing module 101.Illustratively, set in timing module 101 preset timing length as
10s, after main control module 104 starts, the 10s of timing when periodically shutting down in timing module 101 for last time main control module 104 then will
Timer counter in timing module 101 is reset to 0s.Illustratively, set in timing module 101 preset timing length as
10s.When main control module 104, which shuts down, to be completed, timing 7s in timing module 101 is main if main control module 104 turns back at this time
Control module 104 controls timing module 101 and stops timing and timer counter is reset to 0s.
In a kind of possible embodiment, as shown in figure 8, switch control module 102 includes converter DCDC,
Voltage for exporting vehicle power supply is converted to main control module required voltage and timing module required voltage.Due to vehicle
The voltage for carrying power supply is fixed, and voltage required for modules is not identical in mobile unit, will using converter
The voltage of vehicle power supply is converted into modules required voltage in mobile unit, meets the power demand of modules.
In order to preferably explain the present invention, describe that one kind provided by the invention is vehicle-mounted to be set below with reference to specific implement scene
It is standby, as shown in figure 9, including timing module 101, switch control module 102, shutdown detection module 103, main control module 104, logic
Judgment module 107.Logic judgment module 107 includes first diode 1071 and the second diode 1072, and shut down detection module 103
