It is by defining and arranging the judgement symbol variable for judging New Deal or old agreement, and according to judgement symbol variable, selectable controls transfer New Deal communication data or old protocol data, thus new product and old system product receive New Deal communication data and old protocol data selectively, namely new product can receive New Deal communication data or old protocol data, and old system product can receive old protocol data.Thus realize the circle transmission of New Deal communication data and old protocol data.Finally achieve the general of new product and old system product.The function efficiently solving home appliance system is constantly upgraded and is caused the problem that new product and old system product can not be general.
Further, it does not need to increase air-conditioner controller new model in addition, only need change the compatibility that air-conditioner controller software just can realize New Deal and old agreement, decrease cost of development.
Wherein, in step S100, define and arrange in the judgement symbol variable of New Deal and old agreement, comprising step S110, judgement symbol variable being set and equaling preset value.Wherein, judgement symbol variable equals preset value and may correspond to as New Deal, also may correspond to as old agreement.The value of preset value can be 1, also can be 0.
Below with the value of preset value for 1, it is example that judgement symbol variable Flg equals 1 corresponding New Deal, air-conditioner controller communications protocol compatibility processing method of the present invention is done to further describing in detail.
See Fig. 2, step S200, according to judgement symbol variable, controls New Deal communication data or the transmission of old protocol data, comprises the steps:
Step S210, judges whether judgement symbol variable equals preset value; If so, then step S220 is performed; If not, then step S230 is performed.
Step S220, if judgement symbol variable equals preset value, then controls transfer New Deal communication data.
Step S230, if judgement symbol variable is not equal to preset value, then the old protocol data of controls transfer.
Wherein, when the value of preset value is 1, by performing step S210, judge whether judgement symbol variable Flg equals 1.As Flg=1, due to correspondence New Deal when the judgement symbol variable arranged equals preset value (i.e. Flg=1).Therefore, now perform step S220, controls transfer New Deal communication data, realizes New Deal communication data and transfers to goods.When Flg ≠ 1, due to correspondence New Deal when the judgement symbol variable arranged equals preset value (i.e. Flg=1), accordingly, when judgement symbol variable is not equal to preset value (i.e. Flg ≠ 1), then corresponding old agreement.Therefore, now step S230 is performed, the old protocol data of controls transfer.
It is by the judgement symbol variable set up initial value to New Deal and old agreement, i.e. preset value.And by judging the value of judgement symbol variable, selectively carry out the transmission of New Deal and old agreement, achieve new product and can receive New Deal communication data or old protocol data, old system product can receive the object of old protocol data.Solve new product and old system product because of the upgrading of air-conditioner controller communications protocol cause can not be general problem, better can process the stock of old system product, the slow-witted material of old system product can not be caused, and new product and old system product are mixed takes and occur product problem.
