It includes: start control circuit, multiple batteries signal acquisition circuit in place, corresponding multiple signal isolation circuits and corresponding multiple aobvious
Show circuit；It is corresponding that the signal in place of battery by the detection foot of battery is transferred to the battery by battery signal acquisition circuit in place
The signal input port of photoelectrical coupler, the detection foot of battery are a pin on power supply plug-in unit, are patched in battery component
Part is closed guiding path as it to realize the detection whether in place of each battery.Illustratively, by taking battery 1 as an example, battery 1 exists
The voltage signal of position is filtered by the first capacitor C1 being sequentially connected in series and first resistor R1 being connected between 1 positive and negative anodes of battery
Wave processing, two terminals of the first capacitor form the output port of the signal acquisition circuit in place of battery 1, will be filtered place
Reason, the signal in place of electricity 1 for eliminating interference signal are conveyed to corresponding signal isolation circuit, and signal isolation circuit is specifically photoelectricity coupling
Clutch；The photoelectrical coupler is according to the signal in place of the battery 1 received, by electric photoelectric conversion, by the signal in place of battery 1
It is transferred to display circuit and start control circuit respectively by the first signal output port and second signal output port.
On the one hand, multiple signal isolation circuits are sequentially connected in series between the positive and negative anodes of the control power supply in start control circuit
Second signal output port and booting control button.Illustratively, it with reference to Fig. 2, in unmanned plane booting, opens booting control and presses
Button SB1, if there is a battery not in place, start control circuit is disconnected, and the signal in place of any battery is made to directly affect booting
The on-off of control circuit, and then have the function that there is a battery not to be switched on when booting not in place, avoid booting battery leakage
Insert it is not in place caused by take off after heavily loaded pose adjustment allowance is insufficient and aircraft bombing；The second signal output port of start control circuit
It is also connected with point electric control circuit 5, dividing the mode that switching on and shutting down receive main order in electric control circuit 5 is the long triggering of high level, therefore to confession
Electricity divides electric system without influence, when awing there is the case where battery loosening or plug in trouble, in time by aircraft landing, can keep away
Exempt from moment aircraft bombing.
On the other hand, referring to figs. 2 and 3, the first circuit is parallel between the positive and negative anodes of the display power supply in display circuit
