Fig. 3 is the circuit diagram of the described on-line measuring device of the utility model embodiment, wherein, the test connectivity port comprise 5V direct supply, GND (), DATA (synchrodata), CLK (synchronous clock), IR (remote control reception) and KEY (button) interface, be connected with the automatically controlled plate of tested air conditioner during actual the test, therefrom obtain power supply and realize communication; Control circuit comprises IC1 master chip MCU, display driver circuit, buzzer circuit, IC2 reading scan chip, key circuit etc.Wherein, master chip MCU is connected with operation display interface through display driver circuit.
In key circuit, show behind the wind speed button series connection R20 and the R23 dividing potential drop, behind the test button series connection R21 with the R24 dividing potential drop, with the R25 dividing potential drop, when not having button to press, it all is low level that MCU reads behind the reset key series connection R22, when button was pressed, MCU read high level.When pressing the test button, MCU sends the test communication request by communication interface to tested air conditioner; When pressing demonstration wind speed key, read the wind speed of detected air conditioner by communication interface; When reset key is pressed, can makes the test interruption or make the video data zero clearing.
Buzzer circuit comprises resistance R 31, resistance R 30 and triode Q10, and the sounding of hummer is by being finished by triode Q10 driving behind master chip MCU output 2KHz or the 4KHz signal.
Reading scan chip IC 2 can adopt the integrated circuit that seals in and go out, and is used for the reading scan of charactron and LED section stroke; The position that display driver circuit is used for charactron 101, normal pilot lamp 102 and malfunction indicator lamp 103 drives, and display driver circuit can adopt integrated circuit or triode; RT is a paster temperature sensor, by the dividing potential drop of resistance R 11, is changed through A/D by master chip MCU inside, obtains current indoor temperature; Sync cap DATA, CLK is as the connection of automatically controlled plate and pick-up unit, pick-up unit transfers by carrying out data between this interface and the automatically controlled plate of tested air conditioner, the automatically controlled plate of air-conditioning sends the various data that read to pick-up unit, temperature data as the return air temperature sensor in the tested air conditioner, inner blower actual wind speed data, remote signal, compressor current value etc., also send simultaneously the type wire jumper that passes in the air-conditioning or the signal of EEPROM setting value, these setting values comprise the cold or changes in temperature type of the list of air-conditioning, the setting value of wind speed, the current setting value of compressor and four-way valve etc.Earlier by the test button, the MCU in the pick-up unit sends the communication request of test to the MCU of the automatically controlled plate of air conditioner when test, and pick-up unit sends above-mentioned various data request signals to the automatically controlled plate of air-conditioning.
In use earlier the display board plug in the former air-conditioning is pulled down, the test connectivity port is connected with the socket of display board, owing to include 5V, GND, DATA, CLK, IR, KEY interface in the socket of display board, so pick-up unit can take out 5V and GND as working power from the automatically controlled plate of air-conditioning.
After the test connectivity port of pick-up unit and the socket in the tested air conditioner display board connect, press the test button, pick-up unit MCU sends the data communication request to tested air conditioner, enters test procedure as follows:
(1) MCU in the pick-up unit reads the interior type wire jumper of the automatically controlled plate of tested air-conditioning and the actual wind speed of inner blower, obtain wind speed setting in the air-conditioning by the type wire jumper, if the against regulation value of current actual wind speed is promptly confirmed as inner blower or its driving circuit fault;
(2) temperature sensor in the pick-up unit is measured current environmental temperature, the temperature of the return air temperature sensor in detected environment temperature and the tested air conditioner that reads is compared, if current temperature and return air temperature error are promptly confirmed as the return air temperature sensor fault greater than more than 2 degree;
(3) pick-up unit reads the current value of the detected compressor of current transformer in the tested air conditioner by the test connectivity port, the compressor current value and the setting value that read are compared, whether judge compressor fault, when detected current value is greater than or less than the setting value of regulation, promptly confirm as compressor or its driving circuit fault.
(4) mutual inductor that is used for current detecting also can be used for the detection of four-way valve, only the four-way output line also need be added elementary around current transformer, because the electric current of four-way valve is little, lead need add around several circles, because of the conducting of four-way valve ratio piston compressor elder generation, so can be greater than or less than the setting value of regulation when the current value that detects four-way valve than imitating the easy little electric current of effect that recognizes four-way valve, promptly confirm as four-way valve or its driving circuit fault, this project is used for the changes in temperature type.
(5) pick-up unit sense data again after the automatically controlled plate of air-conditioning writes the EEROM test data if the data of data that write and output are unequal, is promptly confirmed as the EEROM fault.
(6) send out the remote control mode formatted data by remote control receiving interface IR to the automatically controlled plate of tested air conditioner, then in the communication interface sense data, if data are unequal, promptly confirm as the remote-control receiving circuit fault, because the effect of remote control receiving interface IR circuit just receives remote signal, its circuit also compares and imitates simply, and the correct reception of remote control mode can determine that its signal passes on the normal of circuit.
(7) read the zero cross signal of power supply, check whether the zero cross signal pulse width is correct, if pulse width greater than error amount, is promptly confirmed as the zero cross signal fault.
If detect normally, normal pilot lamp 102 is bright, finds fault if detect, and malfunction indicator lamp 103 is bright, and charactron 101 shows the fault that coded representation is different, represents EEROM fault etc. as E01, the while buzzer warning.
When the user when showing the wind speed button, after system read current inner blower wind speed, charactron 101 demonstrated current wind speed, can judge the performance and the motor characteristic of current refrigeration in the production of air-conditioning and exploitation better.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
