Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment are only not used in and limit the scope of the invention for the present invention is described.In addition should be understood that, after having read content of the present invention, those skilled in the art can make various changes or modifications the present invention, these equivalent form of values fall within equally the application the scope that limits of attached claims.
Embodiment 1
A kind of automotive air-conditioning system, comprise: temperature sensor, air-conditioning unit, control system and control panel, control system comprises control unit of engine, conditioning control unit, control panel is distinguished connecting engine control unit and conditioning control unit by signal wire (SW), conditioning control unit is by receiving line junction chamber temperature sensor, connect air-conditioning unit by control line, temperature sensor adopts negative temperature coefficient temperature sensor, control panel is provided with the time delays in 5 seconds for pattern discrimination, automotive air-conditioning system is provided with two kinds of mode of operations, be respectively engine mode and battery mode, control system is respectively the separate control system under described two kinds of mode of operations, air-conditioning unit is air vent mode or interior circulation pattern, corresponding dead slow or the adjustable wind speed of being made as of blower fan wind speed of air-conditioning unit, a generator control unit 24V voltage signal of output is to control panel, air-conditioning unit is corresponding to freeze, simultaneously, control panel output 24V voltage signal is given described generator control unit, when described air-conditioning unit refrigeration, when temperature reaches the temperature of described air-conditioning unit setting, air-conditioning unit refrigeration stops automatically, be switched to interior circulation pattern, a 0V voltage signal of control panel output is to control unit of engine, automotive air-conditioning system can switch to battery mode, when under battery mode, described generator control unit output 0V voltage signal is given described control panel, air-conditioning unit is corresponding is interior circulation or air vent mode, simultaneously, control panel output low level signal is given described generator control unit.
Introduce the principle of work of automotive air-conditioning system below:
In the time of engine mode; generator control module can be exported a 24V voltage signal to Air-Conditioning Control Panel; in the time that Air-Conditioning Control Panel detects this signal; car load engine starting is described, air-conditioning can freeze, and opens and does not open and can freely select; when air-conditioning is opened after refrigeration; control panel can be exported a driving engine 24V control signal simultaneously, and this signal is intended to tell driving engine, and air-conditioning does not allow to shut down at refrigeration engine.Through refrigeration after a while, vehicle interior temperature can reduce gradually, in the time that vehicle interior temperature reaches air-conditioning design temperature, now air conditioner refrigerating can stop automatically, is switched to interior circulation pattern, the signal that while panel is exported to driving engine becomes 0, this signal is intended to tell electrical generator, and air conditioner refrigerating stops, and driving engine can quit work and be switched under battery mode, at this time electrical generator can switch also and can not switch, and mainly still will see whether other conditions of car load meet.
In the time of battery mode, generator control module can be exported a 0V voltage signal to Air-Conditioning Control Panel, in the time that Air-Conditioning Control Panel detects this signal, car load engine stop is described, air-conditioning cannot freeze, can only in circulation or air vent mode, according to customer demand now the custom of blower fan can be made as dead slow or adjustable custom, simultaneously to export to the signal of electrical generator be also 0V to control panel.After a period of time, because vehicle interior temperature raises gradually, when being elevated to air-conditioning while being greater than 2 DEG C of design temperatures, vehicle interior temperature can automatically transfer refrigeration mode to, and the signal that control panel is exported to electrical generator simultaneously also becomes 24V, this signal is intended to tell that driving engine vehicle interior temperature is too high, and air-conditioning needs refrigeration.Generator module is receiving after this signal and can judge, and then starter-generator is exported a 24V signal to Air-Conditioning Control Panel simultaneously, and in the time that panel detects this signal, air-conditioning will change refrigeration mode into from air vent mode.
Whole air-conditioning work is as follows: press control panel key, air-conditioning start, first air-conditioning can be according to a state before shutdown, after 5 seconds, control panel can judge now to control to be operated in what pattern, then send instruction, air-conditioner controller receives instruction and does corresponding output, will gather associated temperature judge output with Time Controller.
Compared with prior art, beneficial effect of the present invention is: because control system of the present invention is respectively the separate control system under two kinds of mode of operations, can realize air-conditioning mode of operation in fuel oil operating mode and two kinds of situations of non-fuel oil operating mode, realizing two kinds of operating modes independently controls, when automobile is operated under fuel oil pattern, arbitrarily opening and closing of air-conditioning; When automobile is operated under non-fuel oil pattern, now air-conditioning can be opened also and can close, and environment inside car temperature can regulate automatically according to real-time conditions, ensures the traveling comfort in car.
Be more than the description to the embodiment of the present invention, by the above-mentioned explanation to the disclosed embodiments, make professional and technical personnel in the field can realize or use the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
