Claim 3:
4. A data transmission method in an air conditioning system, wherein the air conditioning system comprises: a centralized air-conditioning controller, at least one air conditioner, and at least one environmental information collection module located in a working area of each air conditioner, wherein the environmental information collection module adopts wireless short-range communication with a corresponding air conditioner, and adopts radio frequency communication with the centralized air-conditioning controller, the method comprising:
when a preset detection time is reached, detecting current environmental data information about an area where the air conditioner that has been matched through networking is located, and by means of wireless short-range communication, sending the current environmental data information to the air conditioner that has been matched through networking;
and when receiving reception acknowledgment information returned by the air conditioner that has been matched through networking, by means of radio frequency communication, sending the current environmental data information and identity identification information about the air conditioner that has been matched through networking to the centralized air-conditioning controller; and
wherein the data transmission method further comprises:
receiving the identity identification information sent by the air conditioner, wherein the identity identification information is sent to the current environmental information collection module when the air conditioner determines that a signal strength of wireless short-range communication signal of the current environmental information collection module satisfies a set condition;
and sending binding feedback information to the air conditioner after the identity identification information is stored.
