The specific embodiment
Below, with reference to description of drawings an embodiment of the invention.
To be that expression is of the present invention possess when frequency convertor system 17 breaks down loss that data keep and the block diagram of the formation of the air conditioner embodiment of Presentation Function to Fig. 1, the 1st, the leaf temperature detecting unit to detecting in the frequency convertor system 17 of air conditioner for the leaf temperature of heat transmission, the motor of compressor 6 is driven by the DC voltage Frequency Converter Control; The 2nd, detect to carrying out the DC voltage detecting unit of the DC voltage that Frequency Converter Control supplies with; The 3rd, detect the motor current detecting unit that flows through the electric current in the compressor.
The control data that Frequency Converter Control portion 4 will be used for drive compression machine 6 stores in the microcomputer, outdoor control part is sent or receives the value and the motor control data of detected leaf temperature, DC voltage, motor current.
Compressor 6 is driven by 4 controls of Frequency Converter Control portion; When abnormality detection unit 5 is unusual at each detected value, be that anomalous signals sends in the Frequency Converter Control portion 4 with each detected value.
Outdoor control part 7 keeps from each detected value and the control data of 4 transmissions of Frequency Converter Control portion, to storage part or upper level transmitting and receiving data; This sends reception essential each detected value and control data nonvolatile storage 8 storages.Indoor control part 9 sends each detected value and the control data that receives from outdoor control part 7, and sends to the remote controller control part.
Export the request signal that will in the display unit in being located at remote controller 13 10, show by sensing element 11, each detected value and the control data that send from indoor control part 9 are sent to the remote controller control part 12, display unit 10 show received respectively detect data and motor control data.
Below, according to the flow chart explanation action embodiment illustrated in fig. 1 of Fig. 3.
When detecting the leaf temperature of regulation, keep this detected value (S1) by Frequency Converter Control portion 4 by leaf temperature detecting unit 1 shown in Figure 1.Then, when detecting certain DC voltage, keep this detected value (S2) by Frequency Converter Control portion 4 by DC voltage detecting unit 2.When detecting the motor current of regulation by motor current detecting unit 3 again, keep this detected value (S3) by Frequency Converter Control portion 4.Learn frequency convertor system 17 drive compression machine 6 under which kind of environment according to this (S1) to the detected value of (S3).Then, Frequency Converter Control portion sends to the detected value of (S1) to (S3) in the outdoor control part 7 (S4).In addition, the motor control data that will be used for drive compression machine 6 in Frequency Converter Control portion 4 sends to outdoor control part 7 (S5).The detected value (S6) that outdoor control part 7 maintenances are received.
So-called motor control data, be that motor number of poles, motor frequency, motor constant etc. are used for drive compression machine 6 necessary data, when frequency convertor system 17 drive compression machines, by motor control data and detected each detected value are sent to outdoor control part 7, can access frequency convertor system 17 is controlled compressor 6 according to which kind of mode under which kind of environment activation bit.Usually, keep the data of specified time limit, repeat this action, until carrying out abnormality detection.
By this action, the information of frequency convertor system 17 is maintained in the outdoor control part 7, therefore, makes system out of service even frequency convertor system 17 is in operation to break down or damage, the activation bit before in the time of also can taking out unusual take place.
Be judged as unusual occasion (S7) by abnormality detection unit 4 detected values, outdoor control part 7 writes nonvolatile storage 8 (S8) with detected value and motor control data.
The abnormality detection unit judges is unusual, the occasion, the dc voltage detection value that surpass the rated temperature of frequency converter at the leaf temperature detected value are proved to be the occasion of the voltage outside the range of operation or the occasion that the motor current detected value surpasses rated current, the activation bit of frequency convertor system 17 when abnormality detection before during, be stored in the memory 8, therefore under what kind of running status, can know whether to occur unusually.
Then, in the occasion of content that will show abnormality, press review button 18, request shows by the unusual content of sensing element 11 to remote controller control part 12 on display unit 10.(S9)
Outdoor control part 7 sends, receives each detected value and control data from remote controller control part 12, and the detected value and the control data of nonvolatile storage 8 sent to remote controller control part 12 (S10).Detected value that is sent and control data show (S11) by display unit 10.
Fig. 2 represents the demonstration of data, after unusual the generation, and by the review button 18 of pressing remote controller 13, detected value and the control data of remote controller control part 12 before when unusual generation of outdoor control part 7 requests.The data of being asked send to the remote controller control part by outdoor control part 7, the data that are sent out are kept by remote controller control part 12, can select leaf temperature detected value, dc voltage detection value, motor current detected value, motor control data and video data with function selector button 19.And press the arrow key that room temperature is set button 20, the data before in the time of can display abnormality takes place on remote controller.By this, can be easily and the activation bit the during abnormality detection of taking out frequency convertor system 17 where necessary at any time, and can promptly make failure cause cheer and bright.
Fig. 4 represents to confirm the example of the two-way communication of frequency converter 17 and outdoor control part 7.In this example, when frequency convertor system 17 for some reason can not two-way communication among the S12, outdoor control part 7 just write nonvolatile storage 8 (S8) with detected value and motor control data.Thereby, even abnormality detection unit 5 is not judged as unusually in frequency convertor system 17, when frequency convertor system 17 can not two-way communication, though for example frequency convertor system 17 break down damage and can not two-way communication the time, also keep, video data.By this,, frequency convertor system 17 damages even stopping fault, the data before also can display abnormality takes place in the display unit 10 of remote controller 13, and therefore, accident analysis is simple and easy, and can rapid cheer and bright failure cause.
