Described AD conversion module also is connected with temperature sensor, can detect the temperature and the environment temperature of automotive air-conditioning system air outlet by this temperature sensor, and temperature value changed into data signal through the AD conversion module, by main process chip be stored in standard value contrast in the data storage.
Described high pressure sensor and low pressure sensor detect the force value of automotive air-conditioning system, and this force value is changed into data signal by the AD conversion module, with this data signal by main process chip be stored in that standard value compares in the data storage.
Described automotive air-conditioning system is connected with high pressure sensor by the high pressure tube connector, is connected with low pressure sensor by low-pressure connection tube.
The utility model can be with air conditioning for automobiles Fault Diagnosis, refrigerant recovering and disposable the finishing of annotating, by main process chip detected pressure, temperature data and standard figures are compared analysis, can find out the failure cause of air conditioning for automobiles fast and accurately, finish refrigerant recovering filling to air conditioning for automobiles, improve the efficient of work greatly, reduced the harmful effect of human factor.
Description of drawings:
Fig. 1 is that pipeline of the present utility model connects block diagram.
Identifier declaration among the figure: high pressure sensor 1, low pressure sensor 2, temperature sensor 3, automotive air-conditioning system 4, high pressure tube connector 5, low-pressure connection tube 6, AD conversion module 7, data processing module 8, data storage 9.
The specific embodiment:
For setting forth thought of the present utility model and purpose, the utility model is described in further details below in conjunction with the drawings and specific embodiments.
See also shown in Figure 1, the utility model is a kind of refrigerant recovering filing provision of integrated air conditioning for automobiles diagnostic function, it mainly comprises a control system that is connected with automotive air-conditioning system 4, wherein this control system is to be made of high pressure sensor 1, low pressure sensor 2, temperature sensor 3, AD conversion module 7, main process chip 8 and data storage 9, wherein high pressure sensor 1, low pressure sensor 2 and temperature sensor 3 are connected with AD conversion module 7 respectively, and AD conversion module 7 then is connected with data storage 9 by main process chip 8.
The utility model is when work, high pressure sensor 1 is by high pressure tube connector 5, low pressure sensor 2 is connected with automotive air-conditioning system 4 respectively by low-pressure connection tube 6, be mainly used in the height that detects automotive air-conditioning system 4, the pressure of low-pressure end, and send detected force value to AD conversion module 7, AD conversion module 7 then changes into data signal with this force value, pass to main process chip 8 then, 8 of main process chip compare analysis with these data signals and the standard figures (referential data) that is stored in data storage 9, here different standard figureses corresponds to different faults, if these numerical value are identical or close with corresponding standard figures, judge that then air-conditioning is corresponding fault, and make corresponding maintenance, as air-conditioning being carried out the refrigerant recovering filling.
Same, also can detect the temperature and the environment temperature of air-conditioner air outlet by temperature sensor 3, and temperature value changed into data signal through AD conversion module 7, by main process chip 8 these data signals and the standard figures (referential data) that is stored in data storage 9 are compared analysis then, draw failure cause.
So that being diagnosed as example, air conditioning for automobiles describes below.At first with high pressure tube connector 5 of the present utility model, low-pressure connection tube 6 is connected respectively to the height of air conditioning for automobiles, on the low pressure port, detect the height of this air-conditioning, low voltage value, on this equipment, import the type of air-conditioning system then, and from data storage 9, call the relevant criterion parameter of the type air-conditioning by main process chip 8, start air conditioning for automobiles this moment, and engine speed is set at 1500RPM, air-conditioning is arranged on maximum refrigerating state, the air-out wind speed is set at secondary, and with this situation running air conditioning for automobiles 15-20 minutes, use temperature sensor probe testing environment temperature then, again with probe clip at air outlet, detect the air outlet temperature.
With above-mentioned detected air-conditioning high-pressure, low pressure, numerical value such as air outlet temperature and environment temperature change into data signal by AD conversion module 7, compare analysis through main process chip 8 and the standard figures (referential data) that is stored in the data storage 9 then, thereby draw corresponding air-conditioning fault.As detect 32 ℃ of environment temperatures, and 9 ℃ of air outlet temperature, low pressure 0.38Mpa, high-pressure 2.21Mpa, this moment, equipment then can provide following possible fault information by comparative analysis: 1, the filling of air-conditioning system inner refrigerant is too much; 2, the refrigeration oil filling is too much in the air-conditioning system; 3, infiltrate air in the air-conditioning system, thereby dwindled the air-conditioning scope of failure greatly.
Can detect the failure cause of air-conditioning system efficiently and accurately by the utility model, and finish, improve the efficient of work greatly automotive air-conditioning system refrigerant recovering filling operation.
More than the refrigerant recovering filing provision of a kind of integrated air conditioning for automobiles diagnostic function provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
