Description
?
Technical field
The invention belongs to technical field of automotive electronics, specially refer to a kind of car load power-off control system.
Background technology
When traditional automobile is in " ON " shelves at key, although car load does not carry out operation, but other electric elements (such as instrument, working lamp, generator excitation etc.) are still in work, can expend like this electric energy of storage battery, even can cause accumulator feeding, if things go on like this, can shorten the service life of storage battery.
Summary of the invention
The objective of the invention is to propose a kind of car load power-off control system, can control the car load power supply according to the automobile service condition, to reduce meaningless waste of energy, the protection storage battery.
Car load power-off control system of the present invention comprises power management module and by the main power switch of described power management module control break-make, is provided with timing unit and level detection unit in the described power management module; Power management module links to each other 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 gear information of the timing of timing unit, automobile ignition switch and electrical generator:
Detect " ON " shelves connection of automobile ignition switch when power management module after, power management module control main power switch is connected, detect simultaneously the charging mouth of electrical generator by level detection unit, when the information of the charging mouth of electrical generator shows that electrical generator is not worked, power management module control timing unit begins timing, after timing arrived the schedule time, power management module control main power switch disconnected; When the information of the charging mouth of electrical generator showed that electrical generator is being worked, power management module control main power switch kept on-state.
Further, described main power switch is relay, and an end of described relay input circuit links to each other with " ON " of automobile ignition switch shelves mouth, and the other end links to each other with the output control pin of power management module; One end of relay output loop links to each other with storage battery, and the other end links to each other with the input end of automobile primary power supply; Whether described power management module connects the break-make of control relay by control output control pin and power supply ground.Come the break-make of indirectly control main power source by relay, can prevent that the flow through electric current of power management module of main power switch is excessive and burn out power management module.
Specifically, described power management module is micro controller system.
Car load power-off control system of the present invention is not when driving engine starts; can the automatic cutout main power source within the regular hour; realize the function of car load outage and protection storage battery; and above-mentioned defencive function can not bring additional operations to the start-up function of car load; the car load timing of can not cutting off the power supply after starting can not bring any impact to the normal use of car load thus.
Description of drawings
Fig. 1 is the structural representation of the car load power-off control system of embodiment 1.
The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the car load power-off control system of present embodiment comprises power management module and by the main power switch of described power management module control break-make, wherein said power management module is micro controller system, and inside is provided with timing unit and level detection unit; Main power switch is that capacity is greater than the relay of 12V*70A.
One end of relay input circuit links to each other with " ON " of automobile ignition switch shelves mouth, and the other end links to each other with the output control pin of power management module; One end of relay output loop links to each other with storage battery, and the other end links to each other with the input end of automobile primary power supply; Whether described power management module connects the break-make of control relay by control output control pin and power supply ground.
Power management module links to each other 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 gear information of the timing of timing unit, automobile ignition switch and electrical generator:
Detect " ON " shelves connection of automobile ignition switch when power management module after, power management module control main power switch is connected, detect simultaneously the charging mouth of electrical generator by level detection unit, when the information of the charging mouth of electrical generator shows that electrical generator is not worked, power management module control timing unit begins timing, after timing arrived the schedule time, power management module control main power switch disconnected; When the information of the charging mouth of electrical generator showed that electrical generator is being worked, power management module control main power switch kept on-state.
Describe principle of work in detail below by example:
1, " ON " shelves also keep, inoperative driving engine when key switch is threaded to, this moment, " ON " shelves signal of automobile ignition switch was high level, because this moment, driving engine was not worked, therefore electrical generator is not worked, the charging output end signal of electrical generator is low level, it is electric that power management module gets relay coil by control output control pin and the connection of power supply ground, the main contact adhesive, and car load main power source system gets electric; Simultaneously power management module control timing unit carries out timing; if timing reaches setting value (such as 10 minutes); then power management module disconnects the relay coil dead electricity by control output control pin and power supply ground; 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, this moment, " ON " shelves signal of automobile ignition switch was high level, it is electric that power management module gets relay coil by control output control pin and the connection of power supply ground, the main contact adhesive, car load main power source system gets electric; Because driving engine can drive electrical generator work in work, so the charging output end signal of electrical generator is high level, the charging output end signal that power management module detects electrical generator is high level, the control timing unit does not carry out timework, thereby make main power switch keep on-state, car load main power source system is sustainable must electric work.
3, after power-off protection function is finished, need car load main power source system again when electric, can by key switch be dialed to " zero " shelves, stir again " ON " shelves and realize; Also can utilize fire an engine by directly key switch being threaded to " START " shelves, the charging output end signal that makes electrical generator is that high level is realized again electricly.
