Accompanying drawing explanation
Fig. 1 is the structural representation of the Overall vehicle power cutoff control system of embodiment 1.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the Overall vehicle power cutoff control system of the present embodiment comprises power management module and is controlled the main power switch of break-make by described power management module, and wherein said power management module is micro controller system, and inside is provided with timing unit and level detection unit; Main power switch is the relay that capacity is greater than 12V*70A.
One end of relay input circuit is connected with " ON " shelves mouth of automobile ignition switch, and the other end is connected with the output control pin of power management module; One end of relay output loop is connected with storage battery, and the other end is connected with the input end of automobile primary power supply; Described power management module is by controlling whether connect control relay break-make with exporting control pin and power supply.
Power management module is connected with the charging mouth of automobile ignition switch, electrical generator respectively, and controls the break-make of main power switch according to the charging mouth information of the timing of timing unit, the gear information of automobile ignition switch and electrical generator:
After power management module detects that " ON " shelves of automobile ignition switch are connected, power management module controls main power switch and connects, detected the charging mouth of electrical generator by level detection unit simultaneously, when the information displaying electrical generator of the charging mouth of electrical generator does not work, power management module controls timing unit and starts timing, after timing arrives the schedule time, power management module controls main power switch and disconnects; When the charging mouth of electrical generator information displaying electrical generator just operationally, power management module control main power switch keep on-state.
Principle of work is described in detail below by example:
1, when key switch is threaded to " ON " shelves and keep, inoperative driving engine, now " ON " shelves signal of automobile ignition switch is high level, because now driving engine does not work, therefore electrical generator does not work, the charging output end signal of electrical generator is low level, that relay coil is obtained is electric by controlling to connect with exporting control pin and power supply for power management module, main contact adhesive, and car load main power source system obtains electric; The timing unit of power management module control simultaneously carries out timing; if timing reaches setting value (as 10 minutes); then power management module is by controlling to disconnect relay coil dead electricity with exporting control pin and power supply; main contact disconnects; car load main power source system cut-off, thus play the effect of power-off protection.
2, after key switch is threaded to " START " shelves start the engine, key switch can be reset to " ON " shelves and keep, now " ON " shelves signal of automobile ignition switch is high level, that relay coil is obtained is electric by controlling to connect with exporting control pin and power supply for power management module, main contact adhesive, car load main power source system obtains electric; Because driving engine is the work of meeting drive electrical generators while work, so the charging output end signal of electrical generator is high level, power management module detects that the charging output end signal of electrical generator is high level, control timing unit and do not carry out timework, thus making main power switch keep on-state, car load main power source system is sustainable obtains electric work.
3, after power-off protection function completes, need car load main power source system again electric time, by key switch being dialed to " zero " shelves, then stir " ON " shelves realize; Also by directly key switch being threaded to " START " shelves, utilize fire an engine, make the charging output end signal of electrical generator be high level realize again electric.
