Description
Technical field
The utility model relates to automobile circuit system technical field, and particularly a kind of have the automatic device cutting off illumination and signal circuit that stops.
Background technology
Part car owner is when stopping, closedown forgotten by light equipment on car or the switch of signalling set, people but have left, and automotive battery electricity is limited, along with time lapse, accumulator electric-quantity will exhaust, due to storage battery over discharge, not only damage battery age, also can cause the consequence that automobile cannot start again, bring larger trouble to car owner.
In order to solve the problem, the patent No. is " the automotive battery electric quantity protective device " of CN201220499946.3, automatically can disconnect the current supply circuit of storage battery, avoid accumulator electric-quantity to consume excessively, guarantee that vehicle can start again.But, this patent is while disconnection storage battery loop, the parts such as the sound equipment on car, Engine ECU are also by power-off, cause the consequences such as sound equipment password loss, time replacement, diagnostic code loss, even some luxury car, after storage battery power-off, the equipment such as sound equipment, by self-locking, need professional to unlock.In addition, other patent about automatic shutdown circuit is not found.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, a kind of parking auto-power-off control device is provided, this device to judge on car unmanned, simultaneously car key extracted and current sensor detects electric current when, time delay a period of time, automatically cut off illumination and signal circuit, but the equipment such as Engine ECU, sound equipment that do not cut off is powered, while maintenance accumulator electric-quantity, also can not have any impact to the normal use of automobile.
For solving the problem, the utility model provides following technical scheme:
A kind of parking auto-power-off control device, illumination and the signal circuit of this control setup and automobile are connected, and comprise the first micro controller system, second singlechip, seating pressure sensor, key status sensor, current status sensor, voice module, loud speaker, circuit breaker and emergency switch; Described first micro controller system is connected with second singlechip; The mouth of described seating pressure sensor is connected with the first micro controller system; The mouth of described key status sensor is connected with second singlechip with the mouth of current status sensor; Described voice module input end is connected with second singlechip; Described loud speaker is connected with the mouth of voice module; Described circuit breaker is connected with illumination and signal circuit; Described emergency switch is in parallel with circuit breaker; The input end of described circuit breaker is connected with second singlechip by aerotron.
Further, each seat bottom of automobile is all provided with a described seating pressure sensor.
Further, described key status sensor is installed near instrument carrier panel key hole.
Further, the input end of described current status sensor is connected with illumination and signal circuit.
Beneficial effect: a kind of parking auto-power-off control device of the present utility model, can be unmanned and forget that when closing illumination or signal lamp, automatic time delay cuts off illumination and signal circuit, keeps accumulator electric-quantity, guarantees that driving engine can start again in car.Can not the power supplys such as Engine ECU be disconnected while cut-out illumination and signal circuit, to avoid the phenomenons such as sound equipment is locked, clock resetting, diagnostic code loss.When parking at night, this device can use as light delay device, illuminates road ahead, allows occupant leave calmly the bad place of light.There is simplicity of design, implement the features such as convenience, dependable performance.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
With reference to the one parking auto-power-off control device shown in Fig. 1, illumination and the signal circuit of this control setup and automobile are connected, and comprise the first micro controller system, second singlechip, seating pressure sensor, key status sensor, current status sensor, voice module, loud speaker, circuit breaker and emergency switch; Described first micro controller system is connected with second singlechip; The mouth of described seating pressure sensor is connected with the first micro controller system; The mouth of described key status sensor is connected with second singlechip with the mouth of current status sensor; Described voice module input end is connected with second singlechip; Described loud speaker is connected with the mouth of voice module; Described circuit breaker is connected with illumination and signal circuit; Described emergency switch is in parallel with circuit breaker; The input end of described circuit breaker is connected with second singlechip by aerotron.
Each seat bottom of automobile is all provided with a described seating pressure sensor.
Described key status sensor is installed near instrument carrier panel key hole.
The input end of described current status sensor is connected with illumination and signal circuit.
Principle of work of the present utility model:
If when chaufeur closes illumination and signal lamp, then current sensor can't detect electric current, then the e port of second singlechip exports 0V, and aerotron ends, and device of the present utility model does not work, and does not cut off illumination and signal circuit.If when chaufeur stops and leaves, car key will be pulled up, car can not have occupant yet, the signal that key is pulled up by key status inductor is input in second singlechip by c port simultaneously; Signal unmanned on car is input to the first micro controller system by all seating pressure sensors (if car, then having 5 seats), and this signal is input to second singlechip by the first micro controller system again; If chaufeur forgets (such as lampet, room light etc.), the then signal that sent by d port accepts current status sensor of second singlechip when closing illuminating lamp or signal lamp.When second singlechip receives that key is pulled up, unmanned on car, light and signal circuit have an electric current, by the plug-in of second singlechip, time delay, after 60 seconds, exports base stage by e port to aerotron VT and controls electric current (time is 5 seconds), triode ON.Circuit: positive source (12V) → breaker coil → aerotron VT → power cathode, breaker coil obtains electric, and its normally closed contact disconnects and keeps, and cuts off illumination and signal circuit, prevents discharged or defective battery.When car key is plugged again, or when having personnel to accomplish on seat, second singlechip passes through f port to voice module output command, the signal language that loud speaker sends " illumination and signal circuit disconnect; please reset ", reminds chaufeur restoring circuit, when manual closing killer switch, loud speaker stops sounding, and the circuit such as illumination restore electricity.
If unmanned on car, key is pulled up, current status sensor detects three conditions in electric current, must possess, this control setup just work, triode ON simultaneously, circuit breaker disconnection, otherwise aerotron ends, and this control setup does not work.
If the equipment installed additional breaks down, after confirming, chaufeur can close emergency switch, maintains normal vehicle operation.
The above, it is only preferred embodiment of the present utility model, not any restriction is made to technical scope of the present utility model, therefore every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
