Embodiment Construction
[0008] Below in conjunction with a preferred embodiment, the invention is further elaborated: the system is to set middleware between the server and the air conditioner, and there are eight 485 serial ports and an Ethernet port on the middleware, and realize TCP / IP to Conversion of RS485 protocol. The eight 485 interfaces of the middleware are plugged with RS485 interface bluetooth modules, and each air conditioner also has an RS485 interface bluetooth module. The SPP protocol of the Bluetooth module realizes point-to-point and point-to-multipoint transparent communication between the air conditioner and the middleware.
[0009] The process of receiving data and instructions by the server: the upper computer of the server (a software system that controls hardware) first sends and receives data instructions, and all operation instruction codes of the air conditioner are stored in the database on the server, and the instruction data is transmitted to the middle through the Ether...
