Number, and after postponing first time period, enable signal is gone to the dc chopper 203 output, controls the dc chopper
203 disconnect, so that the second source and the electronic equipment go off state from state.Wherein, described first when
Between section specifically refer to the lock control circuit 202 and go enable signal elapsed time to output from receiving the first invalid signals.
The first time period can be previously according to needing to be arranged, the cruise duration of the generally less than described second source.
Alternatively, the output end of the detection circuit 201 is also connected with the electronic equipment, the electronic equipment also with
The input terminal of the lock control circuit 202 is connected;Correspondingly, the detection circuit 201 is also used to: when detecting first power supply
When not having electricity output, first invalid signals are exported to the electronic equipment, so that the electronic equipment is when postponing first
Between section the lock control circuit 202 exports the second invalid signals backward.The lock control circuit 202 is specifically also used to: receiving
After stating first invalid signals of detection circuit output and second invalid signals of electronic equipment output, to institute
State the output of dc chopper 203 and go enable signal, control the dc chopper 203 and disconnect so that the second source with
The electronic equipment goes off state from state.Wherein, the first time period is specifically the electronic equipment from connecing
The first invalid signals are received to the second invalid signals elapsed time of output.The first time period can be previously according to needs
Setting, the cruise duration of the generally less than described second source.
The present invention without limiting, such as can represent useful signal with value to the form of the useful signal for 1, be worth and be
0 representative is invalid signals.Alternatively, can also represent useful signal with high level, low level represents invalid signals.
Wherein, dc chopper 203 is a kind of DC-DC converter (DC/DC converter).Dc chopper
Also it is DC interrupter, basic role is the pressure regulation of direct current, can be used for the speed control of direct current generator, exchange type power supplies
Answer etc..Opening and disconnecting for the dc chopper 203 is controlled by the lock control circuit 202, may be controlled to described
The access of power electronic equipment is turned on or off, so that first power supply or second source are the electronic equipment
Power supply stops power supply.Meanwhile the dc chopper 203 can also be by the output of first power supply or the second source
Voltage is converted to the operating voltage of the electronic equipment.The lock control circuit 202 exports enabled letter to the dc chopper 203
Number, it is open-minded to control the dc chopper 203, so that the access is connected, first power supply or the second source
For the power electronic equipment, the electronic equipment described in this way can electrifying startup, start to work.
The power supply management device 200 can be powered by first power supply or the second source.Specifically, the inspection

The output end of the detection circuit 201 is connected with the first control pin of the processing unit of the electronic equipment, and the electronics is set
Second control pin of standby processing unit is connected with the input terminal of the lock control circuit 202;The processing list of the electronic equipment
The signal of first pin described in first periodic polling determines whether first power supply has electricity defeated according to the signal of first pin
Out.For example, first pin, when receiving first invalid signals that the lock control circuit 202 is sent, triggering is interrupted,
Notify the event of the first power outage described in the processing unit of the electronic equipment, then the processing unit of the electronic equipment
Timer will be started, when reaching the first time period, send second invalid signals to the lock control circuit 202.
Wherein, the first time period refers to the processing unit of the electronic equipment from the first invalid signals are received to defeated
Second invalid signals elapsed time out.The first time period can previously according to needing to be arranged, generally less than described
The cruise duration of two power supplys.Certainly, the first time period is also possible to unfixed, by electronic equipment processing unit voluntarily
It when determines to the second invalid signals of lock control circuit output.First time of the processing unit of the electronic equipment in the delay
In section, each processing unit can be notified to carry out necessary processing.For example, the location information of vehicle, log are reported into server,
In order to the information on services of vehicle described in the server analysis.For another example, station network is connected, from server update file etc..
The processing that the present invention does the processing unit of the electronic equipment in the first time period is not limited.
Power supply management device provided in an embodiment of the present invention, it is defeated to the dc chopper by the lock control circuit 202
Enable signal of going out controls opening or disconnecting for the dc chopper 203, when the first power supply has electricity output, preferentially uses the
One power supply is power electronic equipment, is the power electronic equipment by second source after the first power supply does not export electricity, and
In delay certain time, after electronic equipment carries out respective handling, stop ensure that electronic equipment both for the power electronic equipment
The problem of causing second source to exhaust using second source for a long time will not be also avoided, is set to improve by abnormal lower electricity
Standby reliability.
