In the following description, a large amount of concrete details is given to provide more thorough understanding of the invention.But, it will be apparent to one skilled in the art that the present invention can be implemented without the need to these details one or more.In other example, in order to avoid obscuring with the present invention, technical characteristics more well known in the art are not described.
In order to thoroughly understand the present invention, by following description, detailed structure is proposed.Obviously, execution of the present invention is not limited to the specific details that those skilled in the art has the knack of.Preferred embodiment of the present invention is described in detail as follows, but except these are described in detail, the present invention can also have other embodiments.
The invention discloses a kind of multi-gang air-conditioner wireless control method, optionally to control one or more indoor sets of multi-gang air-conditioner.The step that the method mainly comprises can be found out from the flow chart shown in Fig. 1.
First the initialization of hardware is carried out, and setting wireless frequency range, such as can set radio frequency band.Then, whether the radio band set by detection is idle.When detecting that set radio band sends the search signal for searching for target indoor set immediately in this radio band time idle, and wait for that target indoor set sends the first feedback signal.When target indoor set sends the first feedback signal, the first feedback signal that target indoor set is beamed back is verified.First feedback signal is by after verification, first feedback signal is defined as confirm feedback signal, namely target indoor set confirms oneself can be connected, so be labeled as and can connect indoor set by this target indoor set, and it is carried out showing on the display apparatus controlling for user.Simultaneously, by judging to confirm that the power of feedback signal can judge the distance of target indoor set, concrete judgement can use this formula: negative 3 powers of distance=distance coefficient × confirmation feedback signal strength, wherein distance coefficient is the constant that those skilled in the art know, and it is relevant with application scenario environment with wireless chip.After drawing judged result, just can sort to being labeled as the target indoor set that can connect indoor set according to the distance of distance, such as, the distance of target indoor set according to distance be arranged from left to right.When performing the search to target indoor set, each only search target indoor set, along with the execution repeatedly of search step, all upgrades after having searched at every turn, which target indoor set shows currently has be attachable, and what upgrade also has target indoor set according to the sequence of distance simultaneously.Finally, user just can control being labeled as attachable indoor set.
According to multi-gang air-conditioner wireless control method of the present invention, by the step that wireless automatic search and distance identify, neighbouring target indoor set can either be searched for, can also be far and near according to wireless signal strength decipherment distance, and in the display screen display of air-conditioner controller, the distance making user can be marked as the target indoor set that can connect indoor set according to each selectively controls these target indoor sets, thus the installation quantity of multi-gang air-conditioner wireless controller can be reduced, reduce cost, increase the versatility of multi-gang air-conditioner wireless controller simultaneously.
Preferably, method provided by the invention also comprises further: if radio band is busy, then reset new radio band and judge that whether new radio band is busy.If target indoor set does not send the first feedback signal, then this target indoor set being labeled as and can not connecting indoor set, sending the search signal for searching for other target indoor sets subsequently, and wait for that new target indoor set sends the first feedback signal.And when the first feedback signal is not by verification, then target indoor set is labeled as and can not connects indoor set, sending the search signal for searching for other target indoor sets subsequently, and wait for that new target indoor set sends the first feedback signal.
