detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

This embodiment proposes an air conditioner control method, which reduces the transmission time of swing wind information, improves the response speed of swing wind swing blades, and improves user experience. The air conditioner and the control method of the air conditioner will be described below.

The air conditioner mainly includes the main control board of the indoor unit, the display light board, and the swing motor. The main control board of the indoor unit communicates with the display light board, and the display light board controls the operation of the swing motor.

The control method of the air conditioner specifically includes the following steps, as shown in FIG. 1 .

Step S11: the controller sends a control instruction to the main control board of the indoor unit.

When it is necessary to change the operation of the air conditioner, the user sends a control instruction to the main control board of the indoor unit through the controller. The controller is a wire controller, a centralized controller, and the like.

According to the communication protocol between the controller and the main control board of the indoor unit, the control commands sent by the controller to the main control board of the indoor unit include all information such as mode, temperature, wind speed, power on and off, and wind swing information.

Step S12: The main control board of the indoor unit judges whether the swing wind information in the control instruction is the same as the current swing wind information.

After receiving the control command, the main control board of the indoor unit compares whether the swing wind information in the control command is the same as the current swing wind information.

If they are the same, it means that the swing wind information has not changed, and the main control board of the indoor unit performs corresponding operations according to the control commands, and sends the complete control commands to the display light board according to the normal communication sequence.

Refer to Figure 2 for the normal communication sequence between the main control board of the indoor unit and the display light board. The normal data in Fig. 2 is a complete control instruction. A boot code is added before each control command, which is used to identify the following data as a complete control command. In this embodiment, the pilot code is a low level of Xms.

If the swing wind information in the control command is different from the current swing wind information, it means that the swing wind information has changed, and step S13 is executed.

Step S13: The main control board of the indoor unit preferentially sends the swing wind information in the control command to the display light board, and controls the swing wind motor to operate.

Due to the change of the swing wind information, the main control board of the indoor unit sends the changed swing wind information to the display light board first, that is, inserts the swing wind information that needs to be processed first in the normal communication sequence, and then sends the complete control command To the display lamp board, it does not affect the normal communication, as shown in Figure 3. After receiving the wind swing information, the display light board will give priority to controlling the action of the wind swing motor, and then the swing wind and blade action.

It takes Y1ms for a complete control command to be transmitted from the main control board of the indoor unit to the display light board, and Y2ms for the swing wind information to be transmitted from the main control board of the indoor unit to the display light board. Since the swing wind information is less than the complete control command content, so Y2ms is smaller than Y1ms. For example, a complete control instruction usually has more than a dozen bytes. Normally, these more than a dozen bytes are packaged and sent together, and the transfer time required is about two to three seconds (that is, Y1ms shown in Figure 3); The wind information is usually only a few bytes (for example, three bytes), and if only the swing wind information is sent, the transmission time only needs a few hundred milliseconds (Y2ms in Figure 3).

Therefore, in the controller control method of this embodiment, when the swing wind information in the control command is different from the current swing wind information, the main control board of the indoor unit preferentially sends the swing wind information in the control command to the display light board separately, since the The content of the communication transmission greatly reduces the transmission time of the swing wind information, so that the swing wind information can be quickly transmitted to the display light board. The leaf action improves the response speed of the wind and leaf swing, and realizes the fast response of the wind and leaf swing to the command of the controller. After the user changes the swing wind information, he can quickly see the swing wind swing leaf action, which improves the user experience and product competitiveness.

In order to make it easier for the display panel to distinguish between swing wind information and complete control commands (normal data), before the main control board of the indoor unit sends the swing wind information in the control command to the display light board, the indoor unit main control A frame header and a guide code are added before it, and then the frame header, guide code, and swing wind information are sent to the display light board.

The frame header is a continuous low level of Zms and high level of Nms, and the pilot code is low level of Xms, as shown in FIG. 3 . After receiving the low level of Zms, the high level of Nms, and the pilot code, the display lamp board knows that the subsequent data is the swing information.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art can still understand the foregoing embodiments. Modifications are made to the technical solutions described, or equivalent replacements are made to some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed in the present invention.
