Air conditioning system and communication method for wired and wireless message transmission
A wireless terminal performs communication setting processing in response to connection processing from an air conditioning management apparatus. The air conditioning management apparatus sends, to a wireless terminal, a wireless communication electronic message in which an air conditioning communication electronic message is packaged. Upon receipt of the wireless communication electronic message, the wireless terminal converts the content of the communication. Upon receipt of the air conditioning communication electronic message, an air conditioner executes a request command described in the air conditioning communication electronic message. Upon receipt of the air conditioning communication electronic message, the wireless terminal converts the content of the communication. Upon receipt of the wireless communication electronic message, the air conditioning management apparatus performs response reception processing.

the air conditioning management apparatus processor is further configured to perform, in a process of sending and receiving information of the wireless communication electronic messages which are in the second electronic message format respectively to and from the wireless terminal, setting to be used for communication with the air conditioner through the wireless terminal.
4. A communication method in an air conditioning system including an air conditioner that executes control corresponding to request commands in air conditioning communication electronic messages upon receipt thereof, the air condition being connected to a wired transmission line, a wireless terminal connected to the wired transmission line, and an air conditioning management apparatus configured to control the air conditioner,
the method comprising:
a wired communication step of sending and receiving, by the air conditioner, on the wired transmission line, air conditioning communication electronic messages in a first electronic message format for a wired communication respectively to and from the wireless terminal, wherein the first electronic message format includes a communication header and a command, the communication header specifying source and destination addresses on the wired transmission line, the command being a request command to the air conditioner which executes control corresponding to the request command or a response to the request command;
a conversion step of
sending and receiving, by the wireless terminal, on the wired transmission line, the air conditioning communication electronic messages in the first electronic message format respectively to and from the air conditioner,
packaging, by the wireless terminal, received air conditioning communication electronic messages in the first electronic message format into wireless communication electronic messages in a second electronic message format for a wireless communication, and
wirelessly sending and receiving, by the wireless terminal, the wireless communication electronic messages in the second electronic message format respectively to and from the air conditioning management apparatus; and
a wireless communication step of
extracting, by the air conditioning management apparatus, responsive to receipt of the wireless communication electronic messages, the air conditioning communication electronic messages in the first electronic message format from the wireless communication electronic messages in the second electronic message format, and
creating, by the air conditioning management apparatus, the air conditioning communication electronic messages which are in the first electronic message format that are to be sent to the air conditioner, packaging the air conditioning communication electronic messages into the wireless communication electronic messages which are in the second electronic message format to be sent to the wireless terminal, and then sending, by the air conditioning management apparatus, the wireless communication electronic messages in the second electronic message format to the wireless terminal.
5. The communication method according to claim 4 , further comprising, by the wireless terminal
