Description

A kind of back-up source control circuit
Technical field
The utility model belongs to the circuit arrangement or the system field of power supply or distribution, relates in particular to a kind of back-up source control circuit.
Background technology
Unattended electronic equipment is installed on vehicle, need be accomplished the closing automatically of startup, backup battery charging, electronic equipment of electronic equipment simultaneously, the back-up source that is fit to this functional requirement can't be found in market.
The utility model content
The utility model is that a kind of back-up source control circuit that addresses the above problem will be provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of back-up source control circuit; Comprise the automobile storage battery module, immunity module, voltage comparison module one, backup battery module, current switch, isolation module and the electronic device module that connect successively; Also be connected with the JK1 control module between said immunity module and the current switch; Also be connected with voltage comparison module two between backup battery module and the isolation module; Said isolation module also is connected with the CPU processing module, and the CPU processing module also is connected with the JK2 control module with the JK1 control module, and the JK2 control module also is connected with the control end of current switch.
Immunity module is the EMC module, can resist the various interference of EMI/EMS/ESD; Voltage comparison module one comprises voltage comparator and square-wave generator, and the output of voltage comparator links to each other with the input of square-wave generator, and when voltage comparator was output as high level, square-wave generator produced pulse signal and gives the charging of backup battery module; Isolation module comprises DC/DC and ISO, and DC/DC is connected between current switch and the electronic equipment, and ISO is connected between voltage comparison module two and the CPU processing module; Electronic device module comprises watch-dog, stereo set etc.
Use the utility model that following technique effect is arranged:
1, behind automobile starting; The automobile storage battery module is given; After reducing or eliminate the various interference of EMI/EMS/ESD through immunity module EMC; Voltage signal through voltage comparator relatively inputs to square-wave generator with high level signal, produces pulse signal by square-wave generator the backup battery module is charged; Simultaneously also through current switch and isolation module to CPU processing module and power electronic equipment, when the CPU processing module detects the level that is higher than 15.75V, let the normally opened relay JK1 in the JK1 control module get electric self-locking.
2, after automobile stops; The automobile storage battery power supply stops, and this moment, to power electronic equipment, the output that the control of power electronic equipment changes over to by CPU processing module detection voltage comparison module two decided by the backup battery module; When the CPU processing module detects the level that is lower than set point (15.75V); Give the normally opened relay JK1 dead electricity in the JK1 control module immediately, cause current switch to break off after the JK1 dead electricity, thereby realize closing automatically of electronic equipment.
Further, because the square-wave signal frequency stabilization, it is safe and reliable to charge the battery; Said voltage comparison module one comprises voltage comparator and square-wave generator, and the output of voltage comparator links to each other with the input of square-wave generator.
Further, simple in order to make circuit structure, be easy to realize; Said JK1 control module comprises the resistance and the normally opened relay of polyphone.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model technical scheme is further specified:
Fig. 1 is the configuration diagram of a kind of back-up source control circuit of the utility model;
Fig. 2 is the structural representation of a kind of embodiment of a kind of back-up source control circuit of the utility model.
Embodiment
As depicted in figs. 1 and 2; The utility model back-up source control circuit; Comprise the automobile storage battery module, immunity module, voltage comparison module one, backup battery module, current switch, isolation module and the electronic device module that connect successively; Also be connected with the JK1 control module between said immunity module and the current switch, also be connected with voltage comparison module two between backup battery module and the isolation module, said isolation module also is connected with the CPU processing module; The CPU processing module also is connected with the JK2 control module with the JK1 control module, and the JK2 control module also is connected with the control end of current switch.
Said voltage comparison module one comprises voltage comparator and square-wave generator, and the output of voltage comparator links to each other with the input of square-wave generator.
Said JK1 control module comprises the resistance and the normally opened relay of polyphone.
The utility model is behind automobile starting, and storage battery judges that the output signal of ordering through A removes to control square-wave generator A2 for the voltage that electricity is ordered to A through over-voltage comparator A1; The conducting of Control current switch Q1 is gone in the output of A2; To the pulse current charge that backup battery carries out detection with voltage, current switch Q2 conducting simultaneously, isolation module gets; The output of isolation module is connected with electronic equipment, the electronic equipment energising.
The automobile storage battery current supply circuit breaks off, and the control of power electronic equipment is decided by the output that the CPU processing module detects voltage comparator A3, when voltage greater than 15.75V the time; Let the contact JK1 of normally opened relay remain closed; When electrical source consumption when being lower than 15.75V, voltage comparator A3 is output as low, the CPU processing module through being judged as continuously after a while under-voltage effectively after; Give the contact JK1 dead electricity of normally opened relay immediately; Discharge JK1, this moment, the control voltage of current switch Q2 was low immediately, had accomplished the power-off action.
Above embodiment only explains the concrete application of the utility model; Can not be interpreted as qualification to the utility model protection range; So long as adopt the technical scheme of the utility model; Perhaps only be to change or distortion, all fall among the protection range of the utility model through the routine that those of ordinary skill in the art can both make.
