Example Embodiment

[0051]See againimage 3,image 3It is a detailed flow chart of the data transmission method for the wire controller of the air conditioner of the present invention. Such asimage 3As shown, the preferred embodiment of the present invention includes the following steps:

[0052]Step S100: Obtain the falling edge signal of the zero-crossing pulse signal;

[0053]Step S101: Determine whether the falling edge signal of the zero-crossing pulse signal is acquired, if the falling edge signal of the zero-crossing pulse signal is acquired, go to step 102, otherwise return to step S100;

[0054]Step S102: Detect whether the pulse width of the pulse signal of the data received by the wire controller within the set time is not less than the set pulse width, and detect whether the pulse level of the pulse signal of the data received by the wire controller within the set time is stable;

[0055]Step S103: In the case that the pulse width of the pulse signal is not less than the set pulse width and the pulse lev...

Abstract

The invention belongs to the technical field of air conditioners, and particularly relates to a data transmission method for a wire controller of an air conditioner. The invention aims to solve the problems that a wire controller of an existing air conditioner is easy to analyze an interference signal when analyzing data returned by an indoor unit, and the communication is unstable. In order to achieve the purpose, the data transmission method for the wire controller of the air conditioner provided by the invention can prevent the wire controller from communicating with the indoor unit based on the interference signal in a mode of judging stability in advance and avoiding a high-occurrence section of the interference signal to process reply data, so that the situation that the communication between the wire controller and the indoor unit fails due to the fact that the communication is conducted based on the interference signal is avoided, the stability of the communication between thewire controller and the indoor unit is improved, and the air conditioner can run more reliably.

Description

Technical field[0001]The present invention belongs to the technical field of air conditioners, and more particularly to a data transmission method for a wire controller for an air conditioner.Background technique[0002]The air conditioner's wire controller and the indoor unit will issue and return data so that the wire control can obtain the operating parameters of the indoor unit to control the indoor operation.[0003]The data is transmitted between the wire control and the indoor unit. The structural drawback of the above data transmission system is that if the number of indoor machines controlled by the line control is much more, the distance between the different indoor units is far, the communication extension line is longer, and the voltage on the communication line cannot be completely released. A interference signal is formed during the data transfer process. In addition, because the main chip type number of the thread is different, the voltage value of the parsing judgment da...
