Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control apparatus and method using phase angle control communication of an AC power source,

The present invention relates to an apparatus and method for controlling a device using phase angle control communication of an AC power source, and more particularly, to an apparatus and method for controlling an apparatus using an AC power source To a device and a method for controlling the device by transmitting it in a unidirectional direction using the phase angle control of the device.

As a background of the present invention, as disclosed in Korean Patent Registration No. 10-1313002, a method of generating a permutation that combines a waveform in which the phase angle of an AC power source is adjusted and an unadjusted waveform to generate serial data And a communication method.

Generally, in order to remotely control a device using communication, it is common to use a wired / wireless communication network or a power line communication for transmitting data by superimposing an analog communication signal on an AC line.

In the case of using a wired line, a cost for installing a separate communication line increases. In the case of using wireless, installation is simple, but a communication device having a relatively high price compared to a wired line should be used and there is a possibility of data loss due to crosstalk.

Also, in the case of power line communication, although communication is possible by using a power supply line without a separate communication network, there is a problem that it is difficult to use generally because of being vulnerable to disturbance by other electric devices.

Conventional power line communication includes a coupling circuit, a frequency conversion circuit, an SS diffusion, a PN code, a control circuit, and a power supply circuit.

In the case of power line communication using a spread spectrum method widely used in wireless communication, there is a problem that there is a restriction on the power network configuration because communication is not possible when power equipment generating noise in the carrier frequency band exists on the line.

In order to reduce the power by adjusting the output amount of electric heaters and lighting devices using AC power, the phase angle of electric power to be supplied is generally controlled by a SCR (Silicon controlled rectifier) or a transistor, Transformer) is used to control the voltage to control the amount of RMS power supplied. In the case of a power saver that controls the amount of reactive power supplied by controlling the voltage or phase angle, there is a period in which the voltage of the supplied power is lowered or power is not supplied, so that the load device may operate abnormally There is a problem.

Such a correspondence relationship may be changed according to the embodiment.

When the first to third switching signals are on The AC power source 20 is turned off, and in the off state, the AC power source 20 is cut off to output the generated modified AC power.

In this case, the switching unit 240 may be implemented as a semiconductor switching device such as an FET, a transistor, or an IGBT.

The power detection unit 260 detects the amount of power of the AC power source 20 and outputs the detected amount of power to the first control unit 250.

The present invention uses the communication receiver 300 to control a conventional power supply that is unable to analyze phase angle control communication signals.

The second zero voltage detector 330 receives the modified AC power outputted from the switching unit 240 to detect a second zero voltage and a second zero voltage, And outputs it to the control unit 320.

When the second zero voltage point of the modified AC power source is detected, the second control unit 320 sequentially receives the second last voltage point signal and turns off the second second voltage point signal for half a period When the state is maintained, when the off state is continuously maintained, it is determined which of the cases where the state is maintained from the off state to the on state.

Accordingly, when the second positive voltage signal is maintained in the off state and the on state is maintained, the bit is read with the bit value previously matched to the third switching signal. When the off state is continuously maintained, Bit value. When the on-state is maintained in the on-state, the read data is read with a bit value matched with the first switching signal in advance, and the received data packet in which the read bit values are sequentially collected is output. At this time, the second controller 320 may store the generated received data packet.

Further, in the apparatus control apparatus and control method using the phase angle control communication of the AC power supply according to the present invention, when a plurality of communication receivers are configured in one system controller, the system controller controls the communication receivers, And transmits data by transmitting the unique identification information of the device and the transmission object data packet. For this, the second control unit 320 stores the unique identification information, and outputs the received data packet only when the unique identification information stored in the received unique identification information matches the unique identification information of the received data packet, As shown in Fig.

The communication receiver 300 may be included in the device controller 400 or may include a control signal output unit 310 for operating a conventional general device control device and may be a separate product.

That is, the present invention uses a communication receiver 300 to operate a conventional device control device which can not analyze a phase angle control communication signal, and the communication receiver 300 further includes a control signal output unit 310.

At this time, the second controller 310 reads the second last voltage signal transmitted from the second zero voltage detector 330 and outputs the generated second data packet to the control signal output unit 310.

The control signal output unit 310 outputs an output signal that can be recognized by the conventional device control unit in accordance with the received data packet input to the second control unit 320.

When the communication receiver 300 is included in the device controller 400, the third control unit 410 receives the output signal of the control signal output unit 310 and, according to the device control information included in the output signal, And controls the device 500 connected to the third control unit 410.

The third control unit 410 may be a control device included in the device 500 or an external device that transmits a control signal to the control device of the device.

In addition, the system controller 200 may be connected to the control panel 600.

4 is a system controller circuit diagram of an apparatus control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.

First, the first zero voltage detector 230 will be described.

The general AC power supply 20 changes the size and direction of the voltage at a cycle of 50 or 60 Hz. The applied AC power supply 20 drops through the resistor distribution circuits R1, R2, R3 to a voltage recognizable in the circuit. The capacitor C1 connected to the bridge circuits D1, D2, D3 and D4 is charged by a voltage which varies with time, and is discharged through D5 when the voltage is lowered. The photocoupler (OP2) is activated by the voltage charged in C1, and the isolated low signal is input by the voltage point signal input. When the voltage of the AC power source 20 reaches 0 voltage according to the period, C1 is discharged, and the operation of the photocoupler OP2 is stopped and the High signal isolated at the voltage terminal of the voltage point is inputted. Since the zero voltage occurs twice in one cycle of the AC power source 20, the voltage point signal occurs at a cycle twice the AC power source 20 frequency.

Since the circuit principle of the zero voltage detecting unit is commonly used, a further detailed description thereof will be omitted.

The switching unit 240 includes a first FET Q1, a second FET Q2, a photocoupler OP1, a zener diode, and a capacitor.

The first FET Q1 is an N-channel transistor having a drain terminal electrically connected to the AC power source, a source terminal electrically connected to the first ground terminal, and a gate terminal electrically connected to the first node.

The second FET Q2 is an N-channel transistor having a source terminal electrically connected to the first ground terminal, a gate terminal electrically connected to the first node, and a degenerated ac power source outputting a drain terminal.

The photocoupler OP1 has a first end electrically connected to a first resistor connected to the first DC power supply Vcc, a second end electrically connected to a switching signal output terminal of the first control unit, Is electrically connected to a second resistor connected to the second DC power supply (Vdd), the fourth terminal is electrically connected to the second ground terminal, and when a current flows from the first terminal to the second terminal, Current is conducted.

A zener diode is electrically connected between the first node and the second ground terminal.

A capacitor is also electrically connected between the first node and the second ground terminal.

The first through third switching signals output from the switching signal output terminal of the first controller 250 have the same voltage magnitude as the first DC power supply Vcc (for example, 3.3 V) , The magnitude of the off state voltage of the first to third switching signals will be close to 0 V as the Low voltage.

That is, if the voltage applied to the switching signal output terminal of the first controller 250 is the same as the first DC power source Vcc voltage, there is no voltage difference between the first and second ends of the photocoupler, The current does not flow between the third and fourth stages of the first DC power supply Vdd and the second DC power supply Vdd is applied to the first node at a predetermined ratio. Therefore, in this case, the voltage across the first node is higher than the voltage at the first ground terminal, so that the first FET flows from the drain to the source and the second FET flows from the source to the drain , So that the input AC power passes through the drain terminal of the second FET as it is.

If the voltage applied to the switching signal output terminal of the first control unit is the above-described Low voltage, a voltage difference occurs between the first and second ends of the photocoupler to cause a current to flow, so that a current also flows between the third and fourth ends of the photocoupler The voltage of the third stage will drop to the voltage level of the second ground terminal, and the voltage of the first node is also dropped to a voltage of the same magnitude as that of the second ground stage. Therefore, in this case, the voltage applied to the first node becomes equal to the voltage magnitude of the first ground terminal, so that the first node voltage applied to the gate terminal of the first FET and the second FET becomes equal to the first ground terminal, Both the first FET and the second FET are prevented from flowing a current, and finally, the input AC power is cut off.

The phase angle control is operated on the basis of the first positive voltage point signal and the phase angle control circuit is maintained in the ON state until the next first positive voltage point signal is input based on the first positive voltage point signal in a period in which the phase angle is not controlled .

During the control period of the leading edge, the phase angle control circuit is kept in the OFF state during the phase angle control time based on the point of time of the voltage point of the electric potential, and then the phase angle control circuit is kept ON until the next voltage point is inputted.

When controlling the trailing edge, the phase angle control circuit is controlled to ON during the trailing edge control delay time based on the voltage point signal, and the phase angle control circuit is kept OFF during the phase angle control time.

In the present invention, since the combination of the leading edge control waveform, the trailing edge control waveform, and the waveform not controlling the phase angle is generated, the start point of data can be displayed in addition to the data representing the binary data. It is easy to implement general serial communication configured to allow data communication to operate smoothly by displaying the start point of data using the start signal by the start bit.

FIG. 5 is a diagram illustrating waveforms detected through a system controller of an apparatus control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention. FIG. FIG. 7 is a diagram showing waveforms read from a communication receiver of a device control apparatus and method using phase angle control communication of a power source. FIG.

5 and 6, the first controller 250 stores first to third switching signals, and the first to third switching signals are data that are input to the AC power source through the communication unit And a switching signal corresponding to the input data is applied to the switching unit with each of the switching signals corresponding to the start bit, the binary number 1 or 0, and the switching signal corresponding to the input data.

The first switching signal is a signal which is in an off state and is converted into an on-state, the second switching signal is a signal which is kept on continuously, and the third switching signal is a signal which is converted from an on state to an off state.

At this time, the first switching signal is a state in which the switching signal is in the OFF state only for the cut period by cutting the phase of the start part based on the first solar power voltage point of the AC power source, It is a waveform.

The second switching signal is a state in which the switching signal is continuously turned on because there is no phase change with reference to the first solar charging point of the AC power source.

Since the switching signal is off only during the cut period after the phase of the end portion is cut off based on the first positive voltage point of the AC power source, the third switching signal is on until the cutoff period at the first near zero voltage point, State, which is a trailing edge control waveform.

The present invention controls the operation mode of the device in this manner.

When the AC power source 20 is input to the system controller 200, the first zero voltage point of the AC power detected by the first zero voltage detector 230 is input to the first controller 250.

At this time, the first switching signal to be switched from the off state to the on state, the second switching signal to be maintained in the on state, and the third switching signal to be switched from the on state to the off state are stored in the first controller 250, The switching signal, the second switching signal, and the third switching signal are each set to match the start bit or the binary number 1 or the binary number 0, respectively.

For example, when it is assumed that the first switching signal is matched to the binary number 1, the second switching signal is matched to the binary number 0, and the third switching signal is matched to the start bit, the first controller 250 supplies the binary number 1 is input, the switching unit 240 outputs the first switching signal corresponding to the binary number 1 to the switching unit 240.

In response to the first switching signal, the switching unit 240 turns off the AC power in the OFF state, passes the AC power in the ON state, applies the binary number 1 to the AC power, 300).

The second zero voltage detector 330 in the communication receiver 300 detects the second zero voltage point of the deformed AC power source and transmits the second zero point voltage signal to the second controller 320.

At this time, the second control unit 320 is preset with a half period to be determined based on the second last power point.

For example, when the second control unit 320 is instructed to judge based on the half cycle of the modified AC power, the second control unit 320 detects the second nearest power point when the modified AC power is input, At the time when the half period ends.

That is, the second control unit 320 reads the ON / OFF state every time the modified AC power is input and the second local voltage signal is detected, reads the ON / OFF state at the time when the half period ends, Off state or off state, and derives each received data packet accordingly.

Also, the second controller 320 operates only when the switching signal matched with the start bit is input based on the second positive voltage point of the modified AC power source. This is to prevent unnecessary motion due to noise.

For example, in the case of the deformed alternating current power supply, when the second last power voltage point is in the off state and the on state is the second local power point, the time point when the off state is switched to the on state is the data start point.

7 is a view showing an embodiment of a modified AC power source output to a communication receiver of an apparatus control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.

Hereinafter, the AC power source 20 is input to the system controller 200, the data packet 10100101 is input from the external terminal, the first switching signal or the third switching signal is matched with the binary number 1 in the first controller 250, 2 switching signal is set to match the binary number 0 and the second control unit is set to read the half period section based on the second night time point.

Referring to FIG. 7, the second control unit 320 recognizes the start bit S as being started. Here, the start bit is set to the off-state from the second on-state voltage point during the half- And is switched to a switching signal in which the second positive voltage point signal is switched from the off state to the on state. That is, the start bit corresponds to the trailing edge control waveform or the leading edge control waveform.

Then, when the second positive voltage signal for half a period is switched from the OFF state to the ON state based on the second positive voltage point, the bit value binary number 1 matched with the first switching signal is detected.

Then, when the second positive voltage point signal for half a period is maintained in the off state with reference to the second positive voltage point, the bit value binary 0 matched with the second switching signal is detected.

Then, when the second positive voltage signal for half a period is switched from the OFF state to the ON state based on the second positive voltage point, the bit value binary number 1 matched with the first switching signal is detected.

Then, when the second positive voltage point signal for half a period is maintained in the off state with reference to the second positive voltage point, the bit value binary 0 matched with the second switching signal is detected. The next binary 0 is also the bit value due to the same process.

Then, when the second positive voltage signal for half a period is switched from the on state to the off state based on the second positive voltage point, the bit value binary number 1 matched with the third switching signal is detected.

Then, when the second positive voltage point signal for half a period is maintained in the off state with reference to the second positive voltage point, the bit value binary 0 matched with the second switching signal is detected.

Then, when the second positive voltage signal for half a period is switched from the on state to the off state based on the second positive voltage point, the bit value binary number 1 matched with the third switching signal is detected.

As described above, the binary number 1 is a bit value matched with the first switching signal or the third switching signal, and the second positive voltage signal during the half period is switched from the ON state to the OFF state or from the OFF state to the ON state Is output. The binary number 0 is output when the second positive voltage point signal during the half period is maintained in the off state based on the second negative voltage point, which is matched with the second switching signal.

That is, the start bit corresponds to the leading edge control waveform or the trailing edge control waveform, and the data to be transmitted is converted into binary numbers so that the remaining phase angle control waveform corresponds to binary number 1 or binary number 0, The waveform is serially supplied so as to correspond to the complement (01011010) of the binary number 10100101 of the waveform whose phase angle is adjusted, thereby serially transmitting the received data packet to the third control unit 410.

The third controller 410 receives the received data packet 10100101 read from the second controller 320 and controls the operation mode of the connected device 500 based on the device mode control value corresponding to the received data packet. For example, if it is assumed that the device mode control value is the operation mode 2, a signal for operating the operation mode 2 corresponding to the received data packet 10100101 is transmitted to the device.

The switching signal controller 251 receives the first ground voltage signal from the first zero voltage detector 230 and receives the data packet through the input unit 257 or the mode learning unit 254 and outputs a data packet to the first ground voltage point Respectively.

In this case, the switching signal controller 251 may store in advance a first switching signal that is switched from an off state to an on state, a second switching signal that remains on, and a third switching signal that is switched from an on state to an off state have.

When the first zero voltage point is detected at the start of communication, the first zero voltage detector 230 detects the first zero voltage point, and applies the switching signal matched with the start bit to the switching unit 240, And sequentially applies a corresponding switching signal matched with a bit value constituting a transmission target data packet to the switching unit 240 whenever a point is detected.

At this time, the first switching signal or the third switching signal is matched to the start bit, and the remaining two switching signals except for the switching signal matched with the start bit are arbitrarily matched to the binary 1 bit and the binary 0 bit.

That is, the switching signal controller 251 outputs the first switching signal, the second switching signal, or the third switching signal corresponding to the data packet to the switching unit 240 whenever the first ground voltage signal is input.

The plurality of device controllers 400A, 400B, and 400C are connected in parallel to receive a modified AC power source that has passed through the switching unit 240 of the system controller 200. [ The modified AC power supply includes information of a transmission object data packet 10 indicating a device mode control value.

FIG. 10 is a flowchart schematically showing steps of an embodiment of a mode learning method of an apparatus control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.

Fig. 10 (A) shows an embodiment of a mode learning method.

First, the mode learning unit 254 sets all internal counters m and n to 1 (S10).

Then, the power amount detecting unit 260 detects the current amount of power (S21).

next. The mode learning unit 254 transmits the device mode control value for executing the mode m-n to the switching signal control unit 251 so that the device m executes the mode n (S22).

Next, the power amount change calculation unit 253 compares the amount of power detected in step S21 and the amount of power detected after step S22 to calculate a change in the amount of power (step S23).

Then, the mode learning unit 254 transmits the device mode control value for ending the mode m-n to the switching signal control unit 251, thereby causing the device m to terminate the mode n (S24).

Then, the mode learning unit 254 causes the mode data storage unit 252 to store the amount of power calculated in S22 for the mode m-n (S30).

Then, the mode learning unit 254 increments the internal counter n by 1 (S40).

Then, the mode learning unit 254 checks whether an internal counter n exceeds n _m (S50). In this case, n _m is the number of operation modes in which the device m can operate, in the number stored in the mode learning unit 254.

If the counter n does not exceed n _m , the process returns to step S21 to repeat the calculation and storage of the power change for the increased n.

If the counter n exceeds n _m , the mode learning unit 254 increases the internal counter m by 1 and sets n again to 1 (S60).

Then, the mode learning unit 254 checks whether the internal counter m exceeds m _s (S70). In this case, m _s is the number stored in the mode learning unit 254 and the number of devices connected to the system.

If the counter m does not exceed m _s , the flow returns to step S21 to repeat the calculation and storage of the power change for the increased m.

If the counter m exceeds m _s , the mode learning unit 254 ends the operation.

Through the above process, the mode learning unit 254 can repeat the execution and termination of all the operation modes of all the devices connected to the system, and store the change in the power amount for each operation mode in the mode data storage unit 252.

According to an embodiment of the present invention, preferably, in steps S21 to S24, a representative value of the calculated amount of power change data obtained by repeatedly executing a predetermined number of times is set as a power amount of the corresponding operation mode, (252). Through such repetitive execution, it is possible to obtain an effect that more accurate amount of power data can be constructed.

10 (B) shows another embodiment of the mode learning method.

First, the power amount detecting unit 260 detects the current amount of power (S110).

The mode learning unit 254 receives an execution command of the mode mn based on the device mode control value of the data packet 10 input from the input unit 257 through the communication unit 210 or the panel input unit 610 S120).

Then, the switching signal controller 251 generates a switching signal, the switching unit 240 generates a modified AC power according to the switching signal, and the device controller 400 receiving the modified AC power supplies the mode mn (S130).

Then, the power amount change calculation unit 253 compares the amount of power detected in step S110 and the amount of power detected after step S130 (S140).

Then, the mode learning unit 254 causes the mode data storage unit 252 to store the amount of power calculated in S140 for the mode m-n (S150), and ends the operation.

According to an embodiment of the present invention, data of the mode data storage unit 252 can be updated by learning the amount of power data every time control is performed based on the device mode control value of the input data packet 10 .

11 is a diagram schematically illustrating an operation of internal configurations according to a mode identification method of an apparatus control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.

The mode identification unit 255 identifies the operation mode of the device connected to the system based on the power amount data for the operation mode stored in the mode data storage unit 252 and the power amount change derived by the power amount change calculation unit 253 Identify the current operating mode.

For this, the mode identification unit 255 receives a change in the amount of power from the amount of change calculation unit 253 every time the change in the amount of power derived by the amount of change calculation unit 253 is not 0, Compares the power amount data for the operation mode stored in the data storage unit 252, and detects a change in the operation mode and stores the change.

The mode identification unit 255 transmits the identified operation mode change to the communication unit 210 of the system controller 200 and / or the display unit 620 of the control panel 600 through the output unit 258 . The communication unit 210 transmits a change in the received operation mode to an external management apparatus via the external communication network 30, and the display unit 620 outputs a change in the received operation mode to the apparatus.

In addition to the case where the apparatus is controlled by the system controller 200 by identifying the operation mode every time the change in the amount of power derived by the power amount change calculator 253 is not 0, that is, whenever the amount of power is changed, It is possible to identify a change in the operation mode corresponding thereto even when the apparatus is directly controlled and the mode is changed and transmits the identified operation mode to the communication unit 210 or the display unit 620 through the output unit 258, The administrator of the controller 200 can confirm the operation mode. That is, through the operation of the mode identification unit 255, the operation state of the connected device 500 can be fed back under the phase angle control communication of the AC power source capable of transmitting data only in one direction.

12 and 13 are diagrams schematically showing a mode identification method of an apparatus control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.

12 and 13 show the power amount data for each operation mode stored in the mode data storage unit 252 and the amount of power change derived by the power amount change calculation unit 253. The mode data storage unit 252 stores power amount data for each operation mode input by the user or power amount data for each operation mode input according to the operation of the mode learning unit.

The power amount change calculation unit 253 derives a power amount change value according to the time of the power amount detected by the power amount detection unit 260. [ The derived power change value is transmitted to the mode identification unit 255.

The mode identification unit 255 compares the power amount change value received from the power amount change calculation unit 253 with the power amount data of the mode data storage unit 252 to find a value within the same or an error range, .

According to the embodiment shown in FIG. 12, when the power amount change value derived by the power amount change calculation unit 253 is +44 kW and compared with the power amount data stored in the mode data storage unit 252, It is possible to extract the mode 2-1 in the range, and it can be seen that the second device of the system has started the first operation mode. That is, the mode identification unit 255 may assign an error range to the power amount data stored in the mode data storage unit 252 according to a predetermined rule.

If the power change value is -44 kW, it can be determined that the operation mode is ended, not the start of the operation mode.

The mode identifying unit 255 may then transmit the identified change in the operation mode to the communication unit 210 and the display unit 620 through the output unit 258. [

According to the embodiment shown in FIG. 13, when the power amount change value derived by the power amount change calculation unit 253 is +92 kW and compared with the power amount data stored in the mode data storage unit 252, It is possible to extract the modes 1-3 and 2-2 within the range. When the power amount data of two or more operation modes are the same or similar, the operation mode can not be identified only by the power amount change value.

In this case, the mode identification unit 255 can identify the operation mode in such a manner as to control the operation mode of the device 500 connected to the system.

When the mode identification unit 255 can not identify the operation mode only by the amount of change in the amount of electric power, the mode identification unit 255 performs a test to transmit an operation start end command to all operation modes of all devices connected to the system, The change information is compared with the power amount data stored in the mode data storage unit 252 to detect an operation mode that is inconsistent with the data.

In the embodiment shown in FIG. 13, when the operation mode of the actual system is 2-2, when the mode identification unit 255 transmits the end instruction after the operation start of the mode 1-3, The power amount is increased by 90 kW and then decreased by 90 kW similarly to the power amount data. On the other hand, when the mode identification unit 255 transmits the termination command after the start of operation of the mode 2-2, since the mode 2-2 is already in operation, only 90 kW is reduced without increasing the amount of power. At this time, the mode identifying unit 255 identifies the operation mode as the mode 2-2, and again issues the operation start command of the mode 2-2 to make the terminated mode 2-2 operate again.

Preferably, the mode identification unit 255 stores mode data corresponding to a value within the same or an error range as the power amount change value calculated by the power amount change calculation unit 253 without performing a test on all operation modes of all devices Only the operation mode of the power amount data stored in the storage unit 252 is tested to reduce the time required for the test and to prevent the unnecessary operation mode from being performed.

Alternatively, when the operation mode of the device connected to the system exclusively operates with another operation mode, for example, when the mode 1-1 and mode 1-3 are ended by operating the mode 1-2, By testing only one mode, it is possible to identify the device that was in operation and to identify the mode of operation through it.

In the embodiment shown in FIG. 13, when the operation mode of the actual system is 2-2, when the mode identification unit 2550 transmits the end instruction after the start of operation of the mode 1-1, The power amount is increased by 30 kW and then decreased by 30 kW similarly to the power amount data. On the other hand, when the mode identification unit 255 transmits the end instruction after the start of operation of the mode 2-1, since the mode 2-2 is already in operation, the mode 2-1 starts to operate and the mode 2-2 ends , Resulting in a 45 kW reduction in power and a 45 kW reduction in mode 2-1. At this time, the mode identifying unit 255 identifies the operation mode as the mode 2-2, and again issues the operation start command of the mode 2-2 to make the terminated mode 2-2 operate again.

After identifying the operation mode of the system as described above, the mode identification unit 255 can transmit the change of the identified operation mode to the communication unit 210 and the display unit 620 through the output unit 258.

In the device control apparatus according to the embodiment of the present invention, when the device is controlled by the system controller 200, the device is directly controlled by the user and the mode is changed It is possible to identify a change in the operation mode and send the identified operation mode to the communication unit 210 or the display unit 620 via the output unit 258, And can perform integrated management and monitoring of the entire system. That is, through the operation of the mode identification unit 255, the operation state of the connected device 500 can be fed back under the phase angle control communication of the AC power source capable of transmitting data only in one direction.

FIG. 14 is a diagram schematically illustrating the operation of internal components according to an apparatus abnormality determination method of a device control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.

The abnormality determination unit 256 determines whether an abnormality is detected by checking the device mode control value transmitted from the input unit, the data stored in the mode data storage unit, and the amount of power derived from the power amount change calculation unit And determines whether the operation mode is abnormal based on the change.

To this end, whenever the device mode control value is received from the input unit 257, the abnormality determination unit 256 determines whether the device mode control value, the power amount change value derived by the power amount change calculation unit 253, Based on the power amount data for the operation mode stored in the data storage unit 252. [

Upon receiving the device mode control value from the input unit 257, the abnormality determination unit 256 extracts the control information included in the device mode control value, and compares the extracted control information, the power amount change value, and the power amount data It is determined whether the operation mode according to the control information changes without any abnormality. Accordingly, it is possible to determine the operation state of the connected device 500 under the phase angle control communication of the AC power source capable of transmitting the data only in one direction, and to feedback the abnormality according to the operation state.

The abnormality determination unit 256 may directly determine abnormality based on the device mode control value, the power amount change value, and the power amount data. However, the abnormality determination unit 256 may be configured to determine whether the abnormality has occurred, based on the power amount change value and the power amount data And it is also possible to determine whether or not an abnormality is present based on the operation mode. In this case, the abnormality determination unit 256 compares the device mode control value received from the input unit 257 with the operation mode received from the mode identification unit 255, and determines whether the device mode is abnormal.

Thereafter, if there is an error in the operation mode, the abnormality determination unit 256 determines whether or not an abnormality has occurred through the communication unit 210 of the system controller 200, the display unit 620 of the control panel 600, (630). The communication unit 210 transmits the received abnormality to the external management device via the external communication network 30 and the display unit 620 outputs the abnormality to the device. An abnormality can be indicated by a warning light.

FIG. 15 is a view schematically showing a method for discriminating an abnormality in an apparatus control apparatus and method using phase angle control communication of an AC power source according to an embodiment of the present invention.

FIG. 15A schematically shows an abnormality determination method of the abnormality determination unit 256 according to an embodiment of the present invention.

The abnormality determination unit 256 receives the device mode control value from the input unit 257 and extracts the control information from the device mode control value. Thereafter, the abnormality determination unit 256 extracts the amount of power corresponding to the operation mode of the control information from the power amount data of the mode data storage unit 252.
