In addition, the outdoor unit 23a and the plurality of indoor units 36a, 37a, and 38a may transmit and receive control signals to each other.

Conventional air conditioners transmit and receive data at a fixed communication speed and data structure. When the amount of data increases, there is a limitation in scalability as well as a problem in compatibility. In addition, there is a problem in that response time is delayed and network efficiency is deteriorated due to a fixed speed and data structure.

For example, conventional air conditioners generally use only the RS-485 protocol format, which is based on a fixed-size page. For example, the wired remote controller used a protocol with a connected indoor unit and a fixed size of 13 bytes.

When communicating using a protocol of a fixed size as described above, it is difficult to add or expand new functions and delay communication speeds at the present time when functions are complicated and diversified. Particularly, it was difficult to expand the wired remote control other than the (Local) area communication with the connected individual indoor units.

Therefore, the present invention can use a signal according to the TLV (Type Length Value) protocol in which the data size of the wired remote controller is variable in communication with other units.

For example, the first wired remote controller 46a among the plurality of wired remote controllers 46a, 47, and 48 includes indoor units other than the corresponding first indoor unit 36a among the plurality of indoor units 36a, 37a, and 38a. Signals according to the Type Length Value (TLV) protocol may be transmitted and received through the 37a and 38a and the serial communication line 1.

In addition, as in the past, the first wired remote controller 46a can perform local area communication with the corresponding first indoor unit 36a. Even in this case, the first wired remote controller 46a and the first indoor unit 36a can transmit and receive signals having a data structure according to the TLV (Type Length Value) protocol.

4 and 5 are diagrams illustrating a data structure used for communication between units in an air conditioner according to an embodiment of the present invention.

Referring to FIG. 4, units such as a wired remote controller use a data link layer method, which is a second layer, among OSI hierarchies, and data packets used for communication include an address data area and message data. ) Area, cyclic redundancy check (CRC) area for error detection (CRC16). For example, CRC for error detection may be processed as 16-Bit. CRC checksum is used for error detection, but this is not limited, and other error detection methods may be used.

The address data area is composed of an address length including address length information and an address including an address of a sender and an address of a recipient.

The message data area is composed of an application ID, a message type, a sequence number, data length, and data.

At this time, the data Data may have a data structure according to the TLV (Type Length Value) protocol. The TLV protocol is a communication standard that concisely and efficiently expresses complex data into three structured field elements, namely, Type, Length, and Value.

For example, the data Data may be composed of a type field, a length field, and a value field.

In addition, the data (Data) has a size of 0 to 255 bytes (byte), the size of the data value can be changed, the data length can be changed to represent the size of the variable data value.

5 is a diagram illustrating examples of a data area.

As shown in FIG. 5, the data field may be composed of a type, a length, and a data value.

The type is an identifier for information to be included in the data value, the length is the size of the data value, and the data value is actually transmitted information. At this time, the type (Type) is 10bits, the length is 2bits, and the size of the data value varies depending on the type and length.

Event information to be actually delivered is transmitted through a data field by varying the data value according to the type, and the size of the information to be transmitted is variably transmitted.

For example, when the type is 1, the operation mode, and when the type is 2, information about compressor on-off may be transmitted. In addition, when the data length is displayed as 0, 1, 2, or 3 according to the size of information, 4 bits (a), 8 bits (b), 16 bits (c), and 24 bits (d) can be represented, respectively. . The length of information that can be sent as a data value varies depending on the length.

Referring to (a) of FIG. 5, in the basic structure of a data packet, a data type (Length) of data type (Type) occupies a size of 10 bits (bit) and a data length (Len) indicating a size of data value (2) ). The size of the data value basically occupies the size of 4 bits.

Referring to (b), (c), and (d) of FIG. 5, the size of the data value may be expanded in units of 8 bits according to the type. The length Len indicates the size of a variable data value.

Accordingly, it is possible to perform communication at a higher communication speed than conventional outdoor units and indoor units always transmit and receive data of a fixed size. In addition, since the size of data is expandable, it is easy to add new functions to data packets.

Accordingly, the wired remote controller according to the present invention transmits and receives data to and from an indoor device connected by wire directly, and can control indoor devices connected by wire, as well as TLV communication, participate in communication between indoor units and outdoor units, and communication with other indoor units. Can.

Can. For example, the first wired remote control 36a may communicate with the communication units 37b and 38b of other indoor units 37a and 38a through the communication unit 36b of the first indoor unit 36a.

In addition, the wired remote controllers 46a, 47, 48 according to the present invention communicate with the outdoor unit 23a in the remote area through the communication units 36b, 37b, 38b of the indoor units 36a, 37a, 38a in the local area. can do.
