Description
Technical field
The utility model relates to automotive air-conditioning system, especially a kind of air conditioning for automobiles self check warning system.
Background technology
Existing air-conditioning does not have self check and warning system, when air-conditioning breaks down, needs the personage of specialty that air-conditioning is carried out inspection and maintenance, and client just knows guilty culprit, and client is the problem of seeing the air-conditioning system appearance of imagery very.
The utility model content
The purpose of this utility model is the air conditioning for automobiles self check warning system that a kind of timely warning is provided, is convenient to keep in repair.
For achieving the above object, the utility model has adopted following technical scheme: air conditioning for automobiles self check warning system, comprise the warning system message handler, the input end of warning system message handler is gathered the electric signal that engine, automobile air conditioner control panel and each parts of air-conditioning send, the output termination display screen and/or the hummer of warning system message handler are by display screen and/or buzzer warning.
As shown from the above technical solution, the utility model has added the warning system message handler in original automotive air-conditioning system, this message handler can be gathered the electric signal that each parts of engine, automobile air conditioner control panel and air-conditioning send, after judging, export corresponding warning message to display screen and/or hummer and realize reporting to the police.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
Embodiment
A kind of air conditioning for automobiles self check warning system, comprise warning system message handler 1, the input end of warning system message handler 1 is gathered the electric signal that engine, automobile air conditioner control panel 8 and each parts of air-conditioning send, the output termination display screen 2 and/or the hummer 3 of warning system message handler 1, report to the police by display screen 2 and/or hummer 3, described display screen 2 is integrated on the automobile air conditioner control panel 8, or shows on panel board.Native system is monitoring in real time, and the judgement of signal and the investigation of trouble spot are all concentrated on warning system message handler 1, through 1 pair of each signal judgment of warning system message handler and processing, thereby provides corresponding indicating fault.
In conjunction with Fig. 1, the working method of air-conditioning is as follows: at first automobile air conditioner control panel 8 sends signal (high level) and gives control unit of engine ECU, high-voltage tube pressure transducer 7 also sends a magnitude of voltage to control unit of engine ECU simultaneously, control unit of engine ECU is after receiving two signals, judge whether to satisfy and start compressor 9 signals, after meeting the demands, control unit of engine ECU can send the relay K that signal (high level) is given compressor, return to automobile air conditioner control panel 8 one signals simultaneously, it is the working signal of compressor 9, but whether this signal can't finally be confirmed to judge compressor 9 and really work, can only illustrate that control unit of engine ECU sends working signal for compressor 9, another signal that control unit of engine ECU sends gets the relay K coil of compressor, switch is with closure, connect the solenoid control loop of compressor 9, this moment compressor 9 solenoid closure, 9 work of normal condition compressor.
In conjunction with Fig. 1, described warning system message handler 1, its input end is the signal output part of sending and receiving motivation cooling-water temperature sensor 4, engine speed sensor 6, expansion core temperature sensor 5, high-voltage tube pressure transducer 7, control unit of engine ECU and automobile air conditioner control panel 8 respectively, and the output terminal of warning system message handler 1 connects display screen 2 and hummer 3 respectively.The output terminal of described expansion core temperature sensor 5, engine speed sensor 6 links to each other with the signal input part of automobile air conditioner control panel 8 respectively, the signal output part of automobile air conditioner control panel 8 is the input end of sending and receiving motivation control module ECU, warning system message handler 1 respectively, the output terminal of control unit of engine ECU links to each other with compressor 9 by relay K, the other end of compressor 9 is connected with the input end of warning system message handler 1, the input end of the output terminal of control unit of engine ECU system information processor 1 also taking alarm.High-voltage tube is the connection effect, and compressor all belongs to high-voltage tube to that section pipeline between the evaporator.
After car starts, prepare to start air-conditioning, press the AC key or the AUTO key of automobile air conditioner control panel 8, this moment, native system also started simultaneously, warning system message handler 1 receive that expansion core temperature sensor 5 sends the AC signal, control unit of engine ECU signal, the relay K coil signal of compressor 9, the solenoid closure signal of compressor 9, the tach signal that engine speed sensor 6 sends, the signal that engine water temperature sensor 4 sends of temperature signal, pressure signal that high-voltage tube pressure transducer 7 sends, automobile air conditioner control panel 8.Air-conditioning self check warning system is mainly monitored above-mentioned signal, simultaneously to above-mentioned signal, handles by warning system message handler 1, thereby judges the air-conditioning trouble spot.
Judge for failure system, analyze in the following several ways.
1, expansion core temperature sensor 5 provides satisfies the frost-free signal, the tach signal that monitors engine speed sensor 6 simultaneously sends, then the AC signal that has satisfied automobile air conditioner control panel 8 this moment can send, this moment, automobile air conditioner control panel 8 did not send, judge that then automobile air conditioner control panel 8 has problem, to its investigation, demonstration or prompting automobile air conditioner control panel 8 break down.
2, automobile air conditioner control panel 8 sends signal (high level), monitor the magnitude of voltage of high-voltage tube pressure transducer 7 outputs simultaneously, if high-voltage tube pressure transducer 7 does not have signal to send, warning system message handler 1 shows high-voltage tube pressure transducer 7 faults at this moment, though this moment, automobile air conditioner control panel 8 had signal to send, control unit of engine ECU will not send the closure signal of feedback signal and compressor 9.
3, automobile air conditioner control panel 8 sends signal (high level) and monitors the magnitude of voltage of high-voltage tube pressure transducer 7 outputs simultaneously in normally-pressured neighbor; satisfy compressor 9 closure conditions; two signals all input to control unit of engine ECU simultaneously; if this moment, control unit of engine ECU did not send signal; this moment, warning system message handler 1 monitored water temperature that engine water temperature sensor 4 sends in normal range; do not surpass protection domain; then judge control unit of engine ECU fault, show control unit of engine ECU fault.
4, the signal of warning system message handler 1 collection is all monitored normally, control unit of engine ECU sends compressor 9 closure signal simultaneously, but the relay K of compressor 9 is not sent connection signal, investigation relay K and this circuit on-off, and show this line fault and relay K fault.
5, after warning system message handler 1 monitors the connection of relay K circuit, the relay K closure signal is sent simultaneously, but the temperature value that force value that this moment, high-voltage tube pressure transducer 7 sent and expansion core temperature sensor 5 send is no change all, the not action of solenoid valve of compressor 9 is described, judge compressor 9 faults this moment, shows compressor 9 fault alarms on the display screen 2.
In sum, this warning system has added warning system message handler 1 in original automotive air-conditioning system, this message handler can be gathered the electric signal that engine, automobile air conditioner control panel 8 and each parts of air-conditioning send, after judging, exporting corresponding warning message to display screen 2 and/or hummer 3 realizes reporting to the police, point out roughly problem points and maintenance direction to maintenance, thus convenient for maintaining and reduced maintenance cost.
