Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, a kind of power control for glow plug, the drive circuit 4 that it comprises for the voltage sampling circuit 3 of obtaining voltage sampling signal from power supply 1, is used for controlling the MCU control unit 2 of output voltage and is used for driving glow plug work; The end that described voltage sampling circuit 3 is connected with drive circuit all is connected with power supply 1, the other end of described voltage sampling circuit 3 is connected with MCU control unit 2, the other end of described drive circuit 4 is connected with glow plug 5, and described MCU control unit 2 is connected with drive circuit 4; And described drive circuit 4 is realized the separately metal-oxide-semiconductor drive circuit of control for being used for to each glow plug.
Described MCU control unit 2 comprises A/D modular converter 2.1, data processing module 2.2 and signal output module 2.3.
The utility model adopts the metal-oxide-semiconductor drive circuit that the multichannel glow plug is driven respectively, for example can realize that four road glow plugs control separately, open or close respectively, realize that namely first glow plug of four cylinders starts working first, second again, then be the 3rd again, the 4th cylinder is started working at last.Can reduce so the instantaneous operating current of storage battery and line drop, can realize protective action to storage battery and circuit.
In this specific embodiment, the voltage rating of glow plug is 11V.During use, this power control first cylinder glow plug after circuit is connected is started working, the initialization electric current is 20A approximately, and second cylinder glow plug started working again, and the initialization electric current is 20A approximately, the 3rd cylinder glow plug started working again,, the initialization electric current is 20A approximately, and last the 4th cylinder glow plug started working,, the initialization electric current is 20A approximately.Like this, in the whole working procedure, the storage battery supply current about 20A, can not pass through by transient high-current all the time.If do not adopt as above mode of operation, then the initialization electric current of storage battery is about 80A.
