The driving unit 280 may further include an input current detection unit A, a reactor L, and the like.

Hereinafter, the operation of each of the constituent units in the motor driving apparatus 280 of Figs. 7 and 8 will be described.

The reactor L is disposed between the commercial AC power source 405, etc. and the converter 410 to perform a power factor correcting or boosting operation. The reactor L may also function to limit the harmonic current due to the fast switching of the converter 410.

The input current detection section A can detect the input current is inputted from the commercial AC power source 405. [ For this, a current transformer (CT), a shunt resistor, or the like may be used as the input current detector A. The detected input current is may be input to the inverter control unit 430 as a discrete signal in the form of a pulse.

The converter 410 converts the commercial AC power source 405, which has passed through the reactor L, into DC power and outputs the DC power. Although the commercial AC power source 405 is shown as a single-phase AC power source in the figure, it may be a three-phase AC power source. The internal structure of the converter 410 also changes depending on the type of the commercial AC power source 405.

Meanwhile, the converter 410 may include a diode without a switching element, and may perform a rectifying operation without a separate switching operation.

For example, in the case of a single-phase AC power source, four diodes may be used in the form of a bridge, and in the case of a three-phase AC power source, six diodes may be used in the form of a bridge.

On the other hand, the converter 410 may be, for example, a half-bridge type converter in which two switching elements and four diodes are connected, and in the case of a three-phase AC power source, six switching elements and six diodes may be used .

When the converter 410 includes a switching element, the boosting operation, the power factor correction, and the DC power conversion can be performed by the switching operation of the switching element.

However, the present invention is not limited to this, and direct current power may be directly inputted. For example, DC power from the solar cell may be directly input to the smoothing capacitor C or DC / DC converted and input. Hereinafter, the portions illustrated in the drawings are mainly described.

Diodes are connected in anti-parallel to each switching element Sa, S'a, Sb, S'b, Sc, S'c.

The switching elements in the inverter 420 perform ON / OFF operations of the respective switching elements based on the inverter switching control signal Sic from the inverter controller 430. [ Thereby, the three-phase AC power source having the predetermined frequency is outputted to the three-phase synchronous motor 530.

The inverter control unit 430 can control the switching operation of the inverter 420 based on the sensorless method. For this, the inverter control unit 430 can receive the output current io detected by the output current detection unit E.

The inverter control unit 430 outputs the inverter switching control signal Sic to the inverter 420 to control the switching operation of the inverter 420. [ The inverter switching control signal Sic is a switching control signal of a pulse width modulation (PWM) method and is generated and output based on the output current io detected by the output current detection section E. Detailed operation of the output of the inverter switching control signal Sic in the inverter control unit 430 will be described later with reference to Fig.

The output current detection unit E detects the output current io flowing between the inverter 420 and the three-phase motor 530. [ That is, the current flowing in the motor 530 is detected. The output current detection unit E can detect all of the output currents ia, ib, ic of each phase or can detect the output currents of two phases using the three-phase balance.

The output current detection unit E may be located between the inverter 420 and the motor 530. For current detection, a current transformer (CT), a shunt resistor, or the like may be used.

When a shunt resistor is used, three shunt resistors are placed between the inverter 420 and the synchronous motor 530, or three lower arm switching elements S'a, S'b, S'c To be connected to each other. On the other hand, it is also possible to use two shunt resistors using three phase equilibrium.

On the other hand, when one shunt resistor is used, the shunt resistor may be disposed between the capacitor C and the inverter 420 described above.

In the figure, the q-axis current command value (i * q) is exemplified by the current command value, but it is also possible to generate the d-axis current command value (i * d) unlike the figure. On the other hand, the value of the d-axis current command value i * d may be set to zero.

On the other hand, group 2A can transmit 64 characters, and 2B can transmit 32 characters. In addition, the position of the character can be determined by the text segment address codes 1330 and 1430, and can be sequentially incremented by one, starting with " 0000 ".

More specifically, C ₃ , C ₂ , C ₁ , C ₀ is a bit to determine the address of the characters included in the segment, it is possible to select a character to be transmitted.

On the other hand, if the number of characters to be transmitted is 16 segments or less, the end of the sentence may end with 0D (HEX), and the home appliance 200 may wrap when the 0D is encountered in the decoding process.

Since the text A / B flags 1310 and 1410 are toggled (0- > 1 or 1- > 0) when the contents of sent text are changed, if a toggle is detected, the entire sentence is erased and newly received and displayed .

On the other hand, when the same sentence is transmitted, it is preferable to transmit group A and group B individually.

15 is a diagram showing the structure of a group 4A packet among Radio Data System (RDS) data formats.

The difference from FIG. 12 is a Modified Julian Day (MJD) code 1510, a UTC (Universal Time Coordinate) code 1530, and a local time offset 1550.

Referring to the drawing, date information corresponding to year, month, and day may be recorded in the MJD code 1510, and time information corresponding to hour, minute, and second may be recorded in the UTC code 1530. The local time offset can be used to compensate the time difference value for each region when detecting the date information and the time information by combining the MJD code 1510 and the UTC code 1530.

On the other hand, the current time information CT may be included in the group 4A, and the accuracy may be 100 ms. Synchronization of the current time information will be described later.

11 to 15 are merely examples for explaining the structure of the radio data system (RDS) data. The radio signals transmitted by the radio signal transmitters 101, 102 and 103 of the present invention and the radio signals transmitted by the home appliance 200 The radio signal is not limited to the data group illustrated in Figs. 11 to 15. Fig.

16 is a diagram showing a firmware update data configuration.

As described above, the radio signal may include firmware update data 1600, and the firmware update data 1600 may include at least one or more group packets 910. [ For example, the firmware update data 1600 may comprise a group 5A packet, a group 2A packet, a group 0B packet, a group 14A packet, a group 2A packet, a group 4A packet, and the like.

On the other hand, the group packet 910 may include alternate frequency (AF) data, current time information CT, enhanced other network (EON) data, program identification (PI) data, (PTM) data, extended country code (ECC) data, program service (PS) data, scrolling program service (SPC) data, program type (PTY) data, (RT) or radio text plus (RTplus) data, travel announcements (TA) data, traffic program (TP) data, traffic message channel (TMC) data, music / (TDC) data, radio paging (RP) data, in-house application (IH) data, emergency alert system (EWS) data, and Open Data Applications Emitter, may be provided with product information, updates the version information, an error correction code (CRC), at least one of a valid check code.

On the other hand, the program identification (PI) data can be composed of four digits of a country code (1 digit), coverage (1 digit), and broadcasting station number (2 digits) . In addition, the program service (PS) data may indicate the name of the broadcasting station to the user, and may be composed of 8 characters. Program service (PS) data can be transmitted in 2 characters per group, and can be received within 1 to 2 seconds.

The current time information CT may be stored in 3 blocks and 4 blocks of the Radio Data System (RDS) Group 4A packet.

The update data may include the latest firmware update data for firmware update. For example, not only the latest driving course data, the latest operation program data, other program data, and application data but also software update data capable of changing a remote trouble diagnosis cycle, a communication cycle with each control section, and the like can be included. In addition, data that can change the output of the driving unit 280 may be included. In a case where the home appliance 200 is provided with a voice recognition engine, firmware update data of the voice recognition engine may also be included.

The product information may include product information of the firmware update target home appliance 200. For example, the product information may include a target product, a release date, a model name, a manufacturing number, a manufacturing country, and the like. More specifically, it may include information such as " Air conditioner / November 2016 / FQ17M7WWC2 / 302KAJH12345 / Korea ".

The update version information may include version information of update data currently being transmitted and the home appliance 200 may receive a radio signal again if there is an error due to an error correction code (CRC). Also, the home appliance 200 can request retransmission to a broadcasting station or the like through a wireless communication module or the like. Such an error correction code (CRC) may improve the reliability of the firmware update.

In addition, the firmware update data may include a parity bit for error checking of the radio signal transmission process.

On the other hand, program identification (PI) data, program service (PS) data, update data, product information, update version information or error correction codes (CRC) may be transmitted by the Radio Data System . Also, the update data can be transmitted by groups 3B, 4B, 7B, 8B, 9B, 10B, 11A (Open Data Applications: ODA). Further, the current time information CT can be transmitted by the group 4A. However, it is needless to say that the above-described group form is merely an example, and the data, information or code of the present invention is not limited thereto and can also be transmitted by other groups.

Meanwhile, the home appliance 200 may include a decoder for extracting any one of the data in the group packet of the firmware update data 1600.

17 is a flowchart illustrating an operation method of a home appliance according to an embodiment of the present invention.

Referring to the drawings, an external power source may be applied to the home appliance 200 according to an embodiment of the present invention (S1711). In particular, in the case of a seasonal appliance such as the air conditioner 200a, it is usual to apply external power for a limited time in the summer. As described below, when external power is applied, The firmware update can be performed irrespective of whether the firmware update is performed or not.

On the other hand, the radio signal transmitters 101, 102 and 103 can transmit radio signals, and the radio signals can be signals modulated in at least one of frequency modulation (FM), amplitude modulation (AM) and phase modulation have.

When the radio signal is a signal modulated using the frequency modulation (FM) method, the data is multiplexed with the spectral redundancy of the frequency modulation (FM), and the current time information CT, product information, update data, Frequency modulation (FM) multiplex broadcasting. For example, when a radio data system (RDS) scheme is used, the present time information (CT), product information, and update data can be transmitted and transmitted to a 57 KHz carrier frequency.

Meanwhile, the radio signal transmitters (101, 102, 103) can transmit at least any one partial data constituting the completed data, and the plurality of radio transmitters (101, 102, 103) can transmit different radio signals.

On the other hand, the radio signal transmitters 101, 102 and 103 can transmit radio signals in real time as well as in a certain period, for example, minutes or new units. It is also possible to transmit a radio signal at a predetermined time. For example, radio signal transmitters 101, 102, 103 may transmit radio signals at 2 am and may be set by a company or service provider for a period of time.

On the other hand, the radio signal may include firmware update data 1600, and the firmware update data 1600 may include at least one or more group packets 910.

The group packet 910 includes at least one of program identification (PI) data, current time information CT, program service (PS) data, update data, product information, update version information, or error correction code And the home appliance 200 may include a decoder for extracting any one of the data in the group packet of the firmware update data 1600. [

On the other hand, program identification (PI) data, program service (PS) data, update data, product information, update version information or error correction codes (CRC) may be transmitted by the Radio Data System . Also, the update data can be transmitted by groups 3B, 4B, 7B, 8B, 9B, 10B, 11A (Open Data Applications: ODA). Further, the current time information CT can be transmitted by the group 4A. However, it is needless to say that the above-described group form is merely an example, and the data, information or code of the present invention is not limited thereto and can also be transmitted by other groups.

Meanwhile, the home appliance 200 can receive radio signals transmitted by the radio signal transmitters 101, 102, and 103 (S1713). The communication unit 270 may include a tuner for adjusting a radio channel and a demodulator for reconstructing a modulated radio signal and a tuner and a demodulator may be implemented as a single module . Meanwhile, a tuner and a demodulator may be included in the controller 240.

The control unit 240 of the home appliance 200 extracts the current time information CT from the group packet having the current time information CT in step S1715 and transmits the time information on the home appliance 200, (CT) can be synchronized (S1717).

For example, among the radio data system (RDS) groups, the group 4a packet may include the current time information (CT), and the control unit 240 may receive the group 4a packet. The control unit 240 extracts the MJD code 1510, the UTC code 1530 and the local time offset 1550 of the group 4a packet and stores the date information corresponding to the current year, month, The time information of the home appliance 200 can be detected and synchronized with the time information of the home appliance 200.

On the other hand, even the home appliances 200 of the same type may have different versions of firmware supported by the highest version depending on the year of release, model name, and the like. For example, models released in 2011 will support up to firmware 3.0. Models released in 2016 can be supported up to firmware 4.7. Accordingly, the control unit 240 can extract the update version information from the group packet including the update version information. The update unit information includes version information of the update data to be transmitted, information about the supported home appliances 200 and the like May be included.

If the update data supports the firmware update of the home appliance 200 based on the version information of the update data and the version information of the update data is newer than the version of the home appliance 200, Firmware update can be performed.

In seasonal appliances such as the air conditioner 200a, external power is generally applied for a limited time in the summer. Therefore, the time information in the air conditioner 200a may be different from the current time information. In this case, the current time information CT can be synchronized with the time information of the air conditioner 200a through the radio signal, and the firmware update described below can be performed.

After the time synchronization of the home appliance 200, the control unit 240 can analyze whether the synchronized current time is a predetermined time (S1730). If the synchronized current time is not the preset time, the control unit 240 can operate the home appliance 200 in the standby mode (S1731).

On the other hand, if the synchronized current time is a preset time, the controller 240 extracts the update data from the group packet including the update data among the firmware update data, stores the update data in the memory 250, Firmware update can be performed.

More specifically, the control unit 240 may receive a radio signal for time synchronization of the home appliance 200, extract the current time information and synchronize the current time, and based on the synchronized current time information , And may receive a radio signal for firmware update at a predetermined time (S1733). On the other hand, the preset time can be set by the company or the service provider, and can be transmitted included in the firmware update data. In addition, the controller 240 may perform firmware update based on the preset time information in the firmware update data.

For example, a company or a service provider can transmit a firmware update by setting 2 o'clock AM to which the frequency of user use is low to a predetermined time. On the other hand, the control unit 240 can analyze whether the current time is the predetermined time based on the synchronized current time information. If the current time is not 2:00 am, the control unit 240 operates in the update standby mode. If it is, the radio signal for firmware update can be received again.

Meanwhile, the control unit 240 can control the communication unit 270 to receive the radio signal at a preset time. Accordingly, the control unit 240 may cause the communication unit 270 to operate in the standby mode after the current time synchronization process, and operate the communication unit 270 again at a predetermined time, so that the standby power may be reduced.

As described above, the control unit 240 can extract the firmware update data from the radio signal, and the firmware update data can include the group packet including the product information.

The control unit 240 can extract the product information from the firmware update data (S1735). If the product information of the home appliance 200 does not match the product information supported by the firmware update data, the control unit 240 does not update can do.

If the product information of the home appliance 200 matches the product information supported by the firmware update data, the control unit 240 extracts the update data from the group packet including the firmware update data, (S1751). Accordingly, when the product information supported by the firmware update data matches the product information of the home appliance, the home appliance 200 performs firmware update, thereby preventing unnecessary firmware update and preventing an error in the firmware update .

Meanwhile, the update data extraction and storage step may be performed simultaneously with the firmware validity check. To this end, the firmware update data may include a valid check code for validity check, and may include an identifier such as a broadcast station or a server, A hash value, a signature value, or the like.

On the other hand, the control unit 240 can perform the validity check based on the valid check code, and when an error occurs in the validity check process or the update data is not valid, the control unit 240 controls the communication unit 270 to again transmit the radio signal As shown in FIG. In addition, the home appliance 200 may request a retransmission through a wireless communication module to a service provider, such as a broadcasting station or a server.

The home appliance 200 stores the firmware update data at the same time as the validity check, so that it is possible to prevent the error due to the malformed firmware update data.

Meanwhile, when the firmware update data is stored in the memory 250, the home appliance 200 displays the update notification information through the display 292 (S1753), and provides a menu for the user to set whether or not to perform the update can do. On the other hand, after the update notification information is displayed, a user command may be received.

Accordingly, the user can select at least one of whether to perform the update or the execution time (S1755).

For example, the control unit 240 may provide a menu of " Yes " or " No " On the other hand, if the user selects " YES ", the control unit 240 provides a menu for performing update after a predetermined time such as " after 3 hours " A menu for performing an update can be provided.

On the other hand, if the user does not select an update, the home appliance 200 may not update the firmware.

On the other hand, when the user selects the update, the controller 240 extracts the update data from the group packet including the update data among the firmware update data, and performs the firmware update based on the update data ( S1757). For this, the controller 240 may include a decoder, and a tuner, a demodulator, and a decoder may be configured as a single module. In addition, any form for extracting the data signal from the radio signal may be included.

Meanwhile, there may be a case where the user is already using the home appliance 200 at a specific time selected by the user. In this case, the control unit 240 may perform firmware update after the user's use of the home appliance 200 is terminated.

Also, the controller 240 can update the firmware in the standby mode without updating the firmware while the home appliance 200 is in use. Accordingly, there is an advantage that firmware update is possible without restricting the operation of the home appliance 200.

On the other hand, when the plurality of radio transmitters 101, 102, and 103 transmit different radio signals, the control unit 240 may extract certain data and combine them to form one complete data.

For example, when a plurality of radio transmitters (101, 102, 103) transmit different portions of the firmware update data, the control unit 240 extracts the update data from the firmware update data and combines them to form one complete data .

18 is a flowchart illustrating an operation method of a home appliance according to an embodiment of the present invention.

Referring to the drawings, radio signal transmitters (101, 102, 103) are capable of continuously transmitting radio signals. The radio signal may be transmitted at a predetermined time.

The home appliance 200 can operate in the standby mode for a predetermined time (S1810). The predetermined time can be set by the company or the service provider, and can be set to a time when the frequency of use of the user is small.

Meanwhile, the home appliance 200 in the standby mode can receive the radio signal at a predetermined time (S1850).

Meanwhile, as described above, the radio signal may include firmware update data 1600, and the home appliance 200 may extract one or more group packets 910 from the firmware update data 1600. 17, when the product information of the home appliance 200 matches the product information supported by the firmware update data, the process of updating the firmware is also performed in the same manner in FIG. 18 Of course.

Meanwhile, the control unit 240 of the home appliance 200 can receive the radio signal at a predetermined time, extract the firmware update data from the radio signal, and store the firmware update data in the memory 250 (S 1870).

In addition, the control unit 240 may perform firmware update based on the firmware update data. For example, the radio signal transmitters 101, 102, and 103 may transmit a radio signal at 2:00 am, where the frequency of user use is low, and the home appliance 200 receives a radio signal at 2:00 am and performs a firmware update can do.

Accordingly, since the home appliance 200 performs firmware update at a time when the frequency of use of the user is low, there is an advantage that firmware update is possible without restricting the operation of the home appliance 200.
