Accompanying drawing explanation
Fig. 1 is the module frame chart of the utility model air-conditioning fault diagnosis system;
Fig. 2 is air-conditioning state supervising device module frame chart.
Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
As shown in Figure 1, a kind of air-conditioning fault diagnosis system based on body, comprise air-conditioning state supervising device, the air-conditioning state information of acquisition is sent to the body processing server having carried air conditioner main body knowledge base by air-conditioning state supervising device, body processing server issue control instruction also can to air-conditioning state supervising device, and body processing server and hand-held mobile terminal and remote database server all carry out communication.
Body processing server, for the treatment of air conditioner main body knowledge base, namely realizes the operations such as the inquiry to air conditioner main body knowledge base, reasoning and storage.
Mobile terminal has network access facility, can produce alarm signal and show the reason and the fault solution that cause fault.
As shown in Figure 2, air-conditioning state supervising device comprises protocol conversion module, the air-conditioning state information obtained from air-conditioner controller is sent to main control unit by protocol conversion module after protocol conversion, accept the control instruction that main control unit issues simultaneously, by being handed down to air-conditioner controller after the conversion of protocol conversion module, main control unit is connected with display module, and main control unit carries out communication by the signal is far passed module and body processing server, and air-conditioning state supervising device is powered by power module.RS485 or the RS232 connection that air-conditioning state supervising device and air-conditioner controller provide is connected, and sends data to body processing server.
