Embodiment approach
[0051] see again image 3 , image 3 It is a detailed step-by-step flowchart of the data transmission method for the wire controller of the air conditioner according to the present invention. Such as image 3 As shown, a preferred embodiment of the present invention comprises the following steps:
[0052] Step S100: Obtain the falling edge signal of the zero-crossing pulse signal;
[0053] Step S101: Judging whether the falling edge signal of the zero-crossing pulse signal is obtained, if the falling edge signal of the zero-crossing pulse signal is obtained, execute step 102, otherwise return to step S100;
[0054] Step S102: Detect whether the pulse width of the pulse signal of the wire controller receiving data within the set time is not less than the set pulse width, and simultaneously detect whether the pulse level of the pulse signal of the wire controller receiving data within the set time is stable;
[0055] Step S103: When the pulse width of the pulse signal is not...

The invention belongs to the technical field of air conditioners, and in particular relates to a data transmission method for a wire controller of an air conditioner. The invention aims to solve the problems that the wire controller of the existing air conditioner is easy to analyze the interference signal and the communication is unstable when analyzing the data returned by the indoor unit. For this purpose, the data transmission method for the wire controller of the air conditioner of the present invention can prevent the wire controller from communicating with the indoor unit based on the interference signal by pre-judging the stability and avoiding the high-incidence section of the interference signal to process the reply data. In this way, communication failure based on interference signals is avoided, which leads to communication failure between the wire controller and the indoor unit, and the stability of communication between the wire controller and the indoor unit is improved, so that the air conditioner can operate more reliably.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a data transmission method for a wire controller of an air conditioner. Background technique [0002] The wire controller of the air conditioner and the indoor unit will send and return data, so that the wire controller can obtain the operating parameters of the indoor unit and control the operation of the indoor unit. [0003] Data is transmitted between the wire controller and the indoor unit through the communication line. The structural disadvantage of the above data transmission system is that if the number of indoor units controlled by the wire controller is large, the distance between different indoor units is relatively long, and the communication extension line is long, the voltage on the communication line may not be completely released, and further Interference signals are formed during data transmission. In addition, because the main chip model ...
