The utility model content
Because the above-mentioned defective of prior art, technical problem to be solved in the utility model provides a kind of vehicle-mounted many power-supply management systems that can stable power-supplying.
For achieving the above object, the utility model provides a kind of vehicle-mounted many power-supply management systems, comprises treater; The first input end of described treater connects the negative pole of first power module by ignition lock; The positive pole of described first power module is successively by the terminal positive pole that is connected the second source module of the terminal switch with second relay of the switch of first relay; The negative pole of described second source module connects second input end of described treater; First mouth of described treater connects the control end of described first relay; Second mouth of described treater connects the control end of described second relay; Be connected be used to first power lead that powers to the load between described first relay and described second relay; The positive pole of described second source module is connected be used to the second source line that powers to the load.When the load of second source module heavier and when enough electric energy can not be provided, treater sends signal and gives first relay and second relay, control first relay and the second relay conducting, first power module and second source module provide electric energy to load jointly; Put when following to the clean boot current threshold when treater detects the first power module electric weight, treater sends a signal to second electromagnetic valve disconnects it, guarantees that first power module has enough electric energy to start car chassis; In the time of can not starting car chassis when the first power module power shortage, treater can send signal and make its conducting for second electromagnetic valve, thereby make first power module and second source module provide electric energy to starter motor jointly, thereby can ensure that automobile can not influence normal startup because of power shortage.
Further, the 3rd mouth of described treater connects the input end of alarm module, preferable, described alarm module is light-emitting diode, when the dump energy that detects first power module or second source module when treater reaches setting value, treater sends signal and gives alarm module, and alarm module sends the prompting light alerting system according to the signal that receives.
Preferable, described alarm module is combined aural and visual alarm, alarm module not only can provide light alerting system can also send alarm sound, can remind more timely and warn.
Preferable, described treater is micro controller system.
The beneficial effects of the utility model are: the utility model can carry out comprehensive control management to vehicle-mounted direct supply, make whole DC power-supply system be in slave mode in real time, thereby can avoid each load power source, chassis power supply because of the power fail of owing to fill, overcharging, overdischarge causes, can improve stability and the reliability index of total system work greatly.The utility model has well solved the monitoring, management of vehicle-mounted many power supplys and has maximizedly realized resource sharing, and having saved cumbersome installation and the debug process of the control system of being formed by relay and switch, the utility model also has efficient height, advantage such as easy to maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model one specific embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of vehicle-mounted many power-supply management systems are made up of treater 1, ignition lock 2, first power module 3, first relay 4, second relay 5, second source module 6 and alarm module 9; The first input end of described treater 1 connects the negative pole of first power module 3 by ignition lock 2; The positive pole of described first power module 3 is successively by the terminal positive pole that is connected second source module 6 of the terminal switch with second relay 5 of the switch of first relay 4; The negative pole of described second source module 6 connects second input end of described treater 1; First mouth of described treater 1 connects the control end of described first relay 4; Second mouth of described treater 1 connects the control end of described second relay 5; Be connected be used to first power lead 7 that powers to the load between described first relay 4 and described second relay 5; The positive pole of described second source module 6 is connected be used to the second source line 8 that powers to the load.The 3rd mouth of described treater 1 connects the input end of alarm module 9.Described alarm module 9 is light-emitting diode.Described treater 1 is micro controller system.
When the load of second source module heavier and when enough electric energy can not be provided, treater sends signal and gives first relay and second relay, control first relay and the second relay conducting, first power module and second source module provide electric energy to load jointly; Put when following to the clean boot current threshold when treater detects the first power module electric weight, treater sends a signal to second electromagnetic valve disconnects it, guarantees that first power module has enough electric energy to start car chassis; In the time of can not starting car chassis when the first power module power shortage, treater can send signal and make its conducting for second electromagnetic valve, thereby make first power module and second source module provide electric energy to starter motor jointly, thereby can ensure that automobile can not influence normal startup because of power shortage.
