Embodiment Construction
[0019] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.
[0020] The present invention aims to provide a wireless communication system and communication method for the internal and external units of the air conditioner. When other systems occupy the channel, the channel is automatically switched, so as to avoid sharing the communication channel with other systems and ensure the good communication effect of the internal and external units of the air conditioner in the system. There is a technical problem that other systems occupy the channel during the communication between the internal and external units of the existing air-conditioning unit.
[0021] like figure 1 As shown, the wireless communication system for indoor and outdoor air conditioners proposed by the present invention includes an internal air conditioner 11 and an external air conditioner 12, and there are multip...

The invention discloses a wireless communication system and method for air conditioner indoor units and an air conditioner outdoor unit. The problem that channels are occupied by other systems during communication of the indoor units and the outdoor unit of an air conditioner unit is solved. The wireless communication system comprises the air conditioner indoor units and the air conditioner outdoor unit. Each air conditioner indoor unit comprises an indoor unit wireless communication module and an indoor unit fault processing module. The air conditioner outdoor unit comprises an outdoor unit wireless communication module, an outdoor unit fault processing module and a networking channel switching module. The outdoor unit fault processing module controls the outdoor unit wireless communication module to empty air conditioner running data in an EEPROM of the outdoor unit wireless communication module after the outdoor unit fault processing module receives a communication fault notice. The indoor unit fault processing modules control the indoor unit wireless communication modules connected with the indoor unit fault processing modules to empty air conditioner running data in EEPROMs of the indoor unit wireless communication modules after the indoor unit wireless communication modules do not receive data sent by the outdoor unit communication module. The networking channel switching module establishes the channels for the air conditioner outdoor unit and all the air conditioner indoor units in the same system. The technical effect of conducting automatic channel switching after the other systems occupy the channels is achieved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a wireless communication system and a communication method for internal and external units of an air conditioner. Background technique [0002] In the current air-conditioning system, the transmission of data and control signals between the indoor unit and the outdoor unit is realized based on the wired connection between the indoor and outdoor units. Cables are connected between the indoor unit and the outdoor unit of the air conditioner to transmit data and control commands; however, this method requires the installation of a large number of communication wires, and consumes manpower and material resources for installation. [0003] Compared with the wired communication method, in the wireless communication method, it is only necessary to install wireless communication modules in the internal unit and the external unit respectively, and realize the transmis...
