When the controller transmits a control command to the indoor unit, the controller transmits a control command to the outdoor unit connected to the indoor unit, and the outdoor unit transmits the received control command to the corresponding indoor unit.

As described above, in the case of communication using wired communication, data is transmitted step by step according to the connection state of the communication line, rather than being connected to one unit of the plurality of units.

Accordingly, since data of the indoor unit can not be directly transmitted, time delay occurs in data transmission. In addition, since the outdoor unit needs to process data of units other than the outdoor unit data, the load associated therewith increases, and data of a plurality of indoor units must be processed by one outdoor unit. Therefore, .

Also, when monitoring the status of the units through the mobile terminal 200, the data of the indoor unit can not be directly transmitted, so that data can be transmitted and received via the controller 50 and the like. Accordingly, the mobile terminal 200 can not freely communicate with each unit of the air conditioner system, and has a limitation that it must communicate with the higher-level controller 50 in order to receive only the corresponding information from the specific unit, have.

Based on the data received from the outdoor unit 10 and the indoor unit 20, It is possible to judge the operation state of the control unit 10 and judge the abnormality.

As described above, the group is set in the outdoor unit and the indoor unit in consideration of the flow of the refrigerant. However, the communication channel including the controller, the outdoor unit, and the indoor unit may be separately set in addition to the communication channel between the outdoor unit and the indoor unit.

The controller 50 and / or the mobile terminal 200 may set the operation setting of the indoor unit 20 according to the state (temperature or humidity) of the indoor space in which the indoor unit 20 is installed based on the data received from the indoor unit 20 And directly transmits the data according to the operation setting change to the indoor unit. At this time, when the operation setting is changed, the indoor unit transmits the data to the outdoor unit, and accordingly, the outdoor unit also changes the operation.

When the indoor unit 20 is scheduled to perform the operation set at the designated time, the controller 50 can transmit the operation command to the indoor unit and the outdoor unit connected to the indoor unit, and the indoor unit transmits the response to the controller 50 And transmits data on the operation state at predetermined time intervals.

The indoor unit 20 sets the operation corresponding to the data input through the input unit or the data received from the controller 50 and transmits the data to the outdoor unit.

The outdoor unit 10 calculates the data of the received indoor unit and the loads according to the operation states of the plurality of indoor units, and controls the compressor.

The pressure sensors are respectively installed at the inlet and the outlet of the refrigerant pipe, and measure the pressure of the refrigerant flowing in and the pressure of the refrigerant discharged, respectively, and input them to the controller 110. The pressure sensor can be installed not only in refrigerant piping but also in water pipes.

The driving unit 140 supplies operating power to the control target according to a control command of the controller 110 and controls the driving of the target. As described above, in the case of an outdoor unit, the driving unit 140 may include a compressor driving unit, an outdoor fan driving unit, and a valve control unit for controlling the compressor, the outdoor fan, and the valve, respectively. The driving unit 140 applies operating power to each of the compressor, the outdoor fan, the valve, and the like so that the designated operation is performed as the motor operates.

The wireless communication module 120 supports at least one wireless communication method and can communicate with other units according to a control command of the controller 110. [ The wireless communication module 120 transmits / receives data to / from a controller, an outdoor unit, and an indoor unit through a designated wireless communication method, and applies the received data to a control unit.

The wireless communication module 120 sets an address for communication between the units, and converts and processes the data to be transmitted and received. When the operation of the unit is started, the wireless communication module 120 searches for a unit of the same frequency band through wireless communication and confirms the connection. The wireless communication module 120 allocates a temporary address or sets a temporary address to be received during initial operation. In addition, when the wireless communication module 120 performs the address setting in response to the control command of the controller, the wireless communication module 120 may request the product number from the controller and set the address based on the product number. In this case, the product number may be a unique number of the unit, a serial number, a MAC address, and the like.

The control unit 110 controls data input and output through the input unit 150 and the output unit 160, manages data stored in the storage unit 130, and controls transmission and reception of data through the communication unit 200. The control unit 110 detects the connection state and communication state of the communication unit 200 through the connection unit 120 and determines an error.

The control unit 110 generates a control command to operate according to a request from another unit or a set operation setting, and applies the control command to the driving unit 140. Accordingly, the driving unit 140 is configured to operate the connected components, for example, a compressor, an outdoor fan, a valve, an indoor fan, and a wind direction control unit.

In addition, the controller 110 determines an operation state corresponding to data input from a plurality of sensors of the sensing unit 170 while the unit is in operation, determines an abnormality, and outputs an error.

The wireless communication module 120 may be provided inside the unit 100 or may be connected to the unit 100 through a connection unit (not shown). The wireless communication module 120 receives and transmits the data of the unit through the connection unit, and applies the received data to the unit.

Preferably, the wireless communication module 120 can wirelessly communicate with a sub-GHz band using a frequency of a sub-GHz band so that the wireless communication module 120 can communicate with an inner wall surface, a floor surface, an obstacle, and the like. The frequency of the sub-band is excellent in the transmission and rotation characteristics, so that the effect of attenuation on the wall or interlayer obstacle is small. Therefore, it is effective for use in communication of an air conditioner system in which a plurality of units are arranged in a building partitioned by a wall.

The wireless communication module 120 communicates using one of the 400 MHz band and the 900 MHz band, which is a license-exempt band that the sub-band can use for a small-output wireless station. The wireless communication module 120 may optionally use frequencies in the 400 MHz and 900 MHz band, corresponding to different regulations depending on the region or country.

In addition, the wireless communication module 120 may further include a communication module such as Zigbee, Bluetooth, and NFC, which are near-field communication systems.

The wireless communication module 120 may include a plurality of communication modules and may communicate through communication modules that are the same or different from each other in communication with the outdoor unit and other indoor units, with the remote controller, and with the controller. The wireless communication module 120 can communicate with different communication methods according to objects by selectively changing a communication method corresponding to an object to be communicated.

When the wireless communication module 120 uses different channels for communication with the indoor unit and the controller, the wireless communication module 120 can transmit and receive data by setting a channel according to an object to be communicated.

According to the provisions of the Radio Law of the Republic of Korea, for the frequency band of 400 MHz or 900 MHz, 21 channels of 424.7 MHz to 424.95 MHz, 11 channels of 447.8625 MHz to 447.9875 MHz, There are 32 channels of 917 to 923.5 MHz for wireless facilities such as / USN, so that they can communicate using these channels.

The license-exempt frequency bands for countries are 902 to 928 MHz (FCC Part 15.247) for North America and South America and 433 MHz, 915 MHz, 863 to 868 MHz (ETSIEN 300220), Japan 920 to 928 MHz (ARIB STD- , Korea 424 to 447 MHz, 917 to 923.5 MHz (KC), India 865 to 867 MHz (GSR 564 (E)), Australia 433, 915 MHz, South Africa 433 MHz, worldwide 2.4 GHz and 5.725 GHz are available.

Also, in the case of using 2.4 GHz and 5.725 GHz in the world, 90 to 928 MHz are used in North America and South America, 863 to 868 MHz are used in Europe, 920 to 928 MHz in Japan, 917 to 923.5 MHz in Korea, and 865 to 867 MHz in India. The communication is possible.

Since there are obstacles such as interlayer walls and furniture in a building, it is necessary to use a frequency band that can reach signals over a certain distance while passing through obstacles in the building.

In the case of sub-band and ISM band (100MHz, 200MHz, 400MHz, 900MHz), it is advantageous that inter-layer communication is possible because of its excellent penetration characteristics in buildings. However, the length of the antenna is determined according to the band of the transmission frequency. In the case of the 100 MHz band and the 200 MHz band, since the antenna is long, the installation is restricted.

Therefore, it is preferable that the wireless communication module 120 communicate using the frequency band of 400 MHz or 900 MHz among the above-mentioned frequency bands in consideration of inter-layer communication and antenna length.

Meanwhile, the wireless communication module 120 may receive a search signal from the mobile terminal and transmit a response signal in response to the received search signal.

The control unit 110 may control the wireless communication module 120 to perform a set feedback operation upon receiving a signal corresponding to an electronic device search command from the mobile terminal.

The control unit 110 may control the output unit 160 to perform a set feedback operation.

For example, when the output section 160 includes a lamp, the set feedback operation may be an operation in which the lamp is turned on.

Also, when the output unit 160 includes a display, the set feedback operation may be an operation in which the display displays a predetermined image.

Also, when the output unit 160 includes an audio output unit, the set feedback operation may be an operation in which the audio output unit outputs a predetermined sound.

Alternatively, the control unit 110 may control the remote controller to output a visual and / or auditory effect by transmitting a signal to the remote controller connected to the electronic equipment.

Alternatively, the control unit 110 may control the driving unit 140 to perform the set feedback operation.

When the wireless communication module 120 receives a signal corresponding to an electronic device search command from the mobile terminal, the controller 110 sweeps the louver or vane a predetermined number of times, for example, when the unit 100 is an indoor unit. The driving unit 140 can be controlled.

Accordingly, it is possible to quickly and easily find a specific unit among the plurality of units 100 arranged in one building.

According to the embodiment, the search result screen can display the electronic devices on which the response signal is received, based on the type of each electronic device.

Referring to FIG. 12, the search result screen 1200 may display items 1211, 1212, 1221, and 1222 corresponding to the electronic devices receiving the response signal according to the type of the device.

For example, the search result screen 1200 can be divided into an indoor unit item 1210 and an outdoor unit item 1220. In the indoor unit item 1210, items 1211 and 1212 And items 1221 and 1222 corresponding to the outdoor units may be displayed in the outdoor unit item 1220 in the order of magnitude of the response signal.

Fig. 13 shows an example of a search result screen.

13, the search result screen 1300 may include an object (MV) corresponding to the mobile terminal and objects (U1, U2, U3) corresponding to the electronic devices on which the response signal is received.

In this case, the objects (U1, U2, U3) corresponding to the electronic apparatuses to which the response signal is received can be displayed closer to the object (MV) corresponding to the mobile terminal as the response strength of the response signal increases.

13, the distance R1 between the object U1 corresponding to the electronic device having the largest signal strength of the response signal and the object MV corresponding to the mobile terminal is different from the distance between the other objects U2 and U3 Is smaller than the distance (R2, R3) between the objects (MV) corresponding to the terminal. Accordingly, the user can intuitively grasp the device most likely to be located close to the current position due to a large signal strength.

The distances R1, R2, and R3 between the object (U1, U2, U3) corresponding to the electronic apparatus to which the response signal is received and the object (MV) corresponding to the mobile terminal are inversely proportional to the signal intensity of the response signal . Thus, the user can intuitively grasp the relative distance between the current position and each device.
