Hereinafter, a control method of an air conditioner according to the present invention will be described with reference to FIGS. 5 and 6.

FIG. 5 is a diagram illustrating data information transmitted from the display controller 250 to the main microcomputer 200, and FIG. 6 is a diagram illustrating data information transmitted from the main microcomputer 200 to the display controller 250.

As can be seen in Fig. 5, the data TX0, TX1, TX2, TX4 each consists of 8 bits.

The data TX0 has a predetermined data value set by default for error checking, and the upper four bits of the data TX0 indicated by "X" represent "don't care".

Next, the data TX0 contains information related to the operation of the air conditioner. The most significant bit b7 of the data TX1 contains information for adjusting the up and down of the wind discharged from the air conditioner. (b6) contains information for controlling the left and right of the wind discharged from the air conditioner, bit (b5) contains information for controlling the air conditioner in the power saving mode, bit (b4) is air conditioning of the air conditioner Contains information for operating in the "Turbo Z state" to maximize driving ability (or cooling capacity), bit b3 contains information for lowering the set temperature of the air conditioner, and bit b2 is air Bit b1 contains information on whether to operate the air conditioner or stop it, and the least significant bit b0 is discharged from the air conditioner. It contains information about the discharge to enable the discharge direction of the cool air.

Next, the upper four bits b7 to b4 of the data TX2 contain information for determining the amount of wind discharged from the air conditioner (air volume: weak, strong power, etc.), and the bit b3 is air conditioning. The device contains information for operating the air purifier function, and the bit b2 contains information for automatically operating the air conditioner in an optimal state. The bit b1 removes moisture from the room using the air conditioner. Bit b0 contains information on whether to use the air conditioner for cooling or for heating.

Finally, the data TX3 is parity data obtained by performing the exclusive OR operation on the data TX0, TX1, TX2 and 55H, and is transmitted to the main microcomputer 200 together with the data TX0, TX1, TX2. This is to detect a data transmission error that may occur during the transmission process. However, it may be possible not to use the data TX0 and TX3 as necessary.

In connection with the operation, for example, when a command for converting the wind strength from "weak" to "strong" through the touch screen 120 is applied, the display control unit 250 corresponds to the upper level of the data TX2 in response to this command. Reset four bits (b7 to b4). The information of the remaining data is kept in the state in which the operation state of the current air conditioner is displayed as it is.

Next, the display controller 250 transmits the data TX0 to TX3 shown in FIG. 5 to the main microcomputer 200.

The main microcomputer 200 receives the data TX0 to TX3 transmitted from the display controller 250 and compares the data with the state of the current air conditioner. As a result of the comparison, it is recognized that the wind strength has changed from "weak" to "river".

Accordingly, the main microcomputer 200 operates the air conditioner so that the strength of the wind discharged from the air conditioner becomes "strong".

In addition, the main microcomputer 200 transmits the result of the command execution and other information on the operation state of the current air conditioner to the display controller 250.

6 illustrates data information transmitted from the main microcomputer 200 to the display controller 250.

As shown in FIG. 6, the data information transmitted from the main microcomputer 200 to the display controller 250 includes data TX0 to TX9.

In FIG. 6, the data TX0 includes information on a time point at which data is transmitted from the main microcomputer 200 to the display controller 250, and the data TX1 includes information on room temperature, and the data TX2. ) Includes information about a temperature preset or newly set by the user, and the data TX3 is first error check data for checking whether or not an error occurs in the data TX0 to TX2 in the transmission data, and the data TX4 The upper 4 bits of) contain information on whether or not the remote control signal has been received, and the lower 4 bits include information on the operation mode of the air conditioner. The first error check data checks whether or not an error occurs for a part of data information transmitted from the main microcomputer 200 to the display controller 250, and the data information may vary depending on a setting.

In addition, the data TX5 displays the state of the outdoor unit, power saving status, turbo Z, plasma in air cleaning mode, up and down wind direction, left and right wind direction, top and bottom discharge, and predetermined information at a predetermined time from the most significant bit in bits. It is made to include reservation information for.

The data TX6 is second error check data for checking for error occurrence similarly to the data TX3. Unlike the first error check data TX3, the second error check data TX6 is somewhat different in that it checks whether or not an error has occurred with respect to the combination of the data TX0 to TX5. The reason for checking the error once more in this intermediate step is that the amount of information transmitted from the main microcomputer to the display controller is greater than the amount of information transmitted from the microcontroller to the main microcomputer. That is, the data TX6 may be referred to as an error code for complementarily checking an error occurrence that may occur due to a large amount of information transmission. As can be seen above, it can be seen that the second error check data refers to the first error check data. Therefore, there is an advantage that it is possible to double check whether an error occurs.

The data TX7 contains information about the current indoor humidity (humidity is represented by numbers 20 to 99), and the upper four bits of the data TX8 contain information on air freshness and the lower four bits. It contains information about the weather (e.g. sunny, cloudy, cloudy, rain), and the data TX9 is the parity data of the data (TX0, TX1, TX2, ..., TX8) and 55H In this case, the data TX0, TX1, TX2,... TX8 are transmitted to the display controller 250 together with the data TX0, TX1, TX2,... However, it may be possible not to use the data TX3, TX6, TX9 as necessary.

5 and 6, there is a difference in the amount of data information transmitted from the main microcomputer 200 to the display controller 250 and the amount of data information transmitted from the display controller 250 to the main microcomputer 200. . The reason for this difference is because there is additional information acquired by the main microcomputer 200 itself. For example, information on humidity, air cleanliness, weather, and the like may be obtained from the sensor unit 212 directly connected to the main microcomputer 200. Information about this may be collected by the display controller 250 itself. Is not. For this reason, when the information is transmitted to the display controller 250, the additional information is transmitted to the display controller 250.

The data information of FIG. 6 transmitted from the main microcomputer 200 to the display control unit 250 is displayed on the display unit 256. In this case, all the information may be displayed or some information may be displayed according to the operation mode of the air conditioner.

For example, the display unit 256 may display various types of information about the current room temperature, humidity, and weather, as well as the state of the air conditioner (information on power saving mode and wind direction). It is controlled by the display control unit 250.

As can be seen from the above, the data information transmitted from the display controller 250 to the main microcomputer 200 is wind direction information which is information on the direction of wind discharged from the air conditioner, and whether the air conditioner operates in a power saving mode. Power-saving information that indicates, turbo-Z information on whether or not strong cooling, the desired temperature information set by the user, the operation / stop information about the operation or stop of the air conditioner, the moisture of the space that is the target of air conditioning Dehumidification information, which is information about dehumidification operation, artificial intelligence information for optimally operating the air conditioner according to a current state, plasma information for air cleaning, cooling information indicating whether or not to heat and cool the air conditioner, and the air conditioner. Air volume information and the like containing information on the amount of wind discharged.

In addition, the data information transmitted from the main microcomputer 200 to the display controller 250 is wind direction information which is information on the direction of the wind discharged from the air conditioner, and power saving information indicating whether the air conditioner operates in a power saving mode. Turbo-Z information indicating whether or not strong cooling is performed, desired temperature information set by a user, operation / stop information regarding driving or stopping of the air conditioner, and dehumidification operation for removing moisture in a space that is an object of air conditioning. Information about dehumidification, artificial intelligence information for optimal operation of the air conditioner according to the current state, plasma information for the purpose of air cleaning, cooling information indicating whether or not to cool and cool, and the amount of wind discharged from the air conditioner Air volume information containing information about the air, room temperature information of the space targeted for air conditioning, and air condition The current humidity information of the space to be fired, the weather information indicating the state of the current weather, and the air cleanliness information, which is information on the cleanliness of the space to be air-conditioned, are included. Here, the indoor temperature information, the humidity information, the weather information, and the air cleanliness information are information collected by the main microcomputer 200 directly from the sensor unit 212.

S13).

The main microcomputer 200 controls the air conditioner to perform execution of the predetermined operation command. Then, the execution result of the operation command and the information on the current operation state of the air conditioner is transmitted to the display control unit 250 again (S15). In this case, the information on the operation state of the air conditioner transmitted from the main microcomputer 200 to the display control unit 250 may further include information about the room temperature, pressure, humidity, and the like directly collected by the main microcomputer 200. .
