Abstract

Disclosed is a method for adjusting the signal strength. The method is used for an indoor unit in a multiple on-line air conditioning system. The method comprises the steps that father node equipment and child node equipment of a device in the multiple on-line air conditioning system are determined; according to the communication state of the device and the father node equipment and the communication state of the device and the child node equipment, the signal strength of the device is adjusted; the problem that due to manners like manual dialing up, operation is tedious is solved, the device is used for adjusting and controlling according to the communication states, the operation process is simplified, the maintaining cost is reduced, and device stability and reliability are enhanced.

Description

technical field [0001] The invention relates to the technical field of multi-connected air conditioners, in particular to a method and device for adjusting signal strength. Background technique [0002] In a wireless multi-connection system, wireless modules are used between internal and external units to maintain communication. Wireless communication does not need to use communication lines, which greatly reduces the cost and complexity of installation, but it also faces the problem of signal interference and pollution to the surrounding environment. If the signal transmission power of the wireless module is adjusted to the maximum, the signal is the strongest at this time, which can ensure the quality of information transmission, but it will cause the greatest interference and pollution to the environment. [0003] Usually the wireless module is equipped with a selection dial for signal transmission power, and different transmission power levels can be selected according ...
