Description

Device control apparatus and method using phase angle control communication of AC power

The present invention relates to a device control apparatus and method using phase angle control communication of an AC power source, and more particularly, an AC power supply for supplying operation mode data of a control target device transmitted through a wired or wireless communication network or directly to a device. The present invention relates to an apparatus and a method for controlling a device by transmitting in one direction by using phase angle control of a.

As the background technology of the present invention, as disclosed in Korean Patent No. 10-1313002, data for transmitting serial data by generating a permutation of a waveform in which a phase angle of an AC power source is adjusted and a waveform that is not controlled are generated. It relates to a communication method.

In general, in order to control a device remotely using communication, it is common to use a wired / wireless communication network or power line communication that transmits data by superimposing analog communication signals on an AC line.

In case of using a wire, the cost for laying a separate communication line increases, and in the case of using a wire, the installation is simple, but a relatively expensive communication device is required compared to the wire, and there is a possibility of data loss due to crosstalk.

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

Conventional power line communication includes a coupling circuit, a frequency conversion circuit, an SS spread, 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 in that a power network configuration becomes more limited because communication is impossible when a power device generating noise of a carrier frequency band exists on a line.

In order to save power by adjusting the output of heaters and lighting equipment using AC power according to the usage environment, the phase angle of the power supplied using SCR (Silicon controlled rectifier), transistor, etc. is generally controlled. It uses a method of controlling the RMS power supplied by controlling the voltage using a transformer. In the case of a power saver that controls the amount of effective power supplied by controlling the voltage or phase angle, the load may be abnormally operated depending on the characteristics of the load device because the voltage of the supply power is lowered or there is a section in which no power is supplied. There is a problem.

Referring to FIG. 1, an AC power source generally has a characteristic of supplying power having a sinusoidal function having an opposite polarity every 1/2 cycle with a period of 60 Hz or 50 Hz.

As a method of controlling the phase angle of AC power, the leading edge cutting method which controls the phase of the beginning of the waveform based on the zero voltage point existing at 0 degree and 180 degrees, and the phase of the end of the waveform There is a trailing edge control method. In this case, in the method of controlling the phase angle, only the leading edge control method or the trailing edge control method may be used, or the leading edge control method and the trailing edge control method may be used in combination.

In one embodiment of the device control apparatus of the present invention, the system receiver 200 sequentially combines the waveforms of the leading edges, the trailing edges, and the phase angles of the communication receivers 300. The received data packet is transmitted to the third controller 410 by supplying to the third controller 410.

Alternatively, the device control apparatus of the present invention can transmit the data packet by performing ON or OFF control of the AC power, or scheduled ON or OFF control through the switching unit in the vicinity of the zero voltage point or in the region of the preset range at the zero voltage point. have. Here, the scheduled ON or OFF control is to control two or more ON and OFF in the region of the predetermined range at the zero voltage point according to the scheduled time.

The present invention communicates data by inserting start bits or binary data into leading edge control waveforms, trailing edge control waveforms, and uncontrolled waveforms in a method of controlling a phase angle.

As an example, the start bit corresponds to a leading edge control trail or a trailing edge control waveform, and data to be transmitted is converted into binary so that the remaining phase angle control waveform corresponds to binary 1 or binary 0, and the phase angle is adjusted. The non-corrugated waveforms may be sequentially supplied to correspond to the complement of the binary values of the waveform whose phase angle is adjusted, thereby serially transmitting the received data packet to the third controller 410.

Such a correspondence may be changed according to an embodiment.

Referring to FIG. 2, the device control apparatus of the present invention includes a system controller 200, a communication receiver 300, a device controller 400, and a control panel 600.

The system controller 200 includes a communication unit 210, a power supply unit 220, a first zero voltage detection unit 230, a switching unit 240, a first control unit 250, and a power amount detection unit 260.

The power supply unit 220 rectifies the AC power supply 20 to supply power required for the first control unit 250 and the communication unit 210.

The communication unit 210 receives a transmission target data packet 10 related to control of devices from an external terminal through the wired / wireless communication network 30 and outputs the received data packet 10 to the first control unit 250. In this case, the data packet 10 may be a start bit, binary 1 or binary 0, or may be converted into a start bit, binary 1 or binary 0.

The first zero voltage detector 230 detects the first zero voltage point at which the voltage of the AC power becomes zero and outputs the first zero voltage point signal to the first controller 250.

The first controller 250 receives the first zero voltage point signal from the first zero voltage detector 230, receives the data packet through the communication unit 210, and converts the signal into a signal corresponding to the data packet at the first zero voltage point. The switching unit 240 is controlled.

At this time, according to an embodiment of the present invention, the first control unit 250 includes a first switching signal that is switched from an off state to an on state, a second switching signal that remains on, and a first state that is switched from an on state to an off state. 3 The switching signal is stored in advance. Such a switching signal may vary depending on the embodiment.

The first zero voltage point is detected from the first zero voltage detector 230, and when the first zero point is detected at the start of communication, a switching signal matched to the start bit is applied to the switching unit 240, and then the first zero voltage point is applied. Each time a point is detected, the corresponding switching signal matched to the bit value constituting the data packet to be transmitted is sequentially applied to the switching unit 240.

In this case, the first switching signal or the third switching signal is matched to the start bit, and the other two switching signals except the switching signal matched to the start bit are arbitrarily matched to the binary 1 bit and the binary 0 bit, respectively. Such a switching signal may vary depending on the embodiment.

That is, each time the first zero voltage point signal is input, the first controller 250 outputs a first switching signal, a second switching signal, or a third switching signal corresponding to the data packet to the switching unit 240.

The first controller 250 reads the data packet 10 received from the external terminal through the communication unit 210. If the read data is a device control signal, a corresponding switching signal is generated and output to the switching unit.

When the switching unit 240 receives the AC power source 20 and receives the first switching signal to the third switching signal from the first control unit 250, the switching unit 240 is in the on state. The alternating current power source 20 passes through the alternating current power source 20 and, in the off state, cuts off the alternating current power source 20 to output the generated alternating current power source.

At this time, the switching unit 240 may be implemented as a semiconductor switching device such as FET, Transistor, IGBT.

The power amount detector 260 detects the power amount of the AC power source 20 and outputs the power amount to the first controller 250. Through the change in the amount of power detected by the power amount detection unit 260, it is possible to monitor the operation state of the connected device to identify the operation mode, and examine whether the operation is abnormal. The operation mode identification method and the error determination method will be described later.

The second controller 320 sequentially receives the second zero voltage point signal, and when the second zero voltage point of the modified AC power source is detected, the second zero voltage point signal for half a cycle is turned off in the on state based on the time point. In the case of maintaining the state, the case in which the case of maintaining the off state in the off state is determined.

Accordingly, when the second zero voltage point signal is maintained in the off state, the second zero voltage point signal is read with a bit value previously matched to the third switching signal, and when the second zero voltage point signal is continuously maintained, the second zero voltage point signal is previously matched to the second switching signal. In the case of reading the bit value and maintaining the off state in the on state, the read data packet is read out using the bit value matched with the first switching signal in advance, and the received data packet is collected by sequentially collecting the read bit values. In this case, the second controller 320 may store the generated received data packet.

In addition, the device control apparatus and control method using the phase angle control communication of the AC power supply of the present invention, when a plurality of communication receivers are configured in one system controller, the communication controller or control target that the system controller wants to control each communication receiver Data is communicated by sending the device's unique identification information and the data packet to be transmitted. To this end, the second controller 320 stores the unique identification information and outputs a received data packet only when the stored unique identification information and the unique identification information of the received data packet match or the device 500 according to the received data packet. Outputs a control signal.

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

In other words, the present invention uses a communication receiver 300 to operate a conventional device control device that can not analyze the phase angle control communication signal, the communication receiver 300 further includes a control signal output unit 310. .

The control signal output unit 310 outputs an output signal that can be recognized by the conventional device control apparatus according to 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 controller 410 receives the output signal of the control signal output unit 310 and according to the device control information included in the output signal. The device 500 connected to the third control unit 410 is controlled.

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

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

The first controller 250 of the system controller 200 reads a signal input through the control panel 600, and generates a switching signal corresponding to the read data when the read data is device control information. Will output

In addition, the first to third switching signals output from the switching signal output terminal of the first control unit 250, the voltage level of the on state is the same as the magnitude (for example 3.3V) of the first DC power supply (Vcc). The off-state voltage magnitude of the first to third switching signals will be nearly 0 volts as a low voltage.

That is, if the voltage applied to the switching signal output terminal of the first control unit 250 is the same as the Vcc voltage of the first DC power supply, there is no voltage difference between the first end and the second end of the photocoupler, and thus no current flows. Since no current flows between the third and fourth stages of the second node, the first node receives a voltage at which the second DC power supply Vdd is divided at a constant rate. Therefore, in this case, the voltage applied to the first node is higher than the voltage of the first ground terminal so that current flows from the drain to the source direction, and the second FET flows from the source to the drain direction. As a result, 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 low voltage described above, a voltage difference is generated between the first and second ends of the photocoupler, so that current flows. As a result, the voltage of the third terminal drops to the magnitude of the voltage of the second ground terminal, and thus the voltage of the first node also falls to a voltage similar to that of the second ground terminal. Therefore, in this case, the voltage applied to the first node is equal to the voltage of the first ground terminal, and thus the first node voltage applied to the gate terminals of the first FET and the second FET is equal to the first ground terminal. In both the first FET and the second FET, no current flows, and eventually the AC power input is interrupted.

Phase angle control operates on the basis of the first zero voltage point signal, and maintains the phase angle control circuit in the ON state until the next input of the zero voltage point signal on the basis of the first zero voltage point signal in a period where the phase angle is not controlled. .

In the period of controlling the leading edge, the phase angle control circuit is kept OFF for the phase angle control time based on the zero voltage point signal, and the phase angle control circuit is kept ON until the next zero voltage point signal is input.

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

According to the present invention, three combinations of a leading edge control waveform, a trailing edge control waveform, and a waveform having no phase angle control are generated. Therefore, the starting point of the data can be displayed in addition to the case of representing the data in response to the binary data. By indicating the start point of the data by using the start signal by the start bit, it is easy to implement general serial communication configured to facilitate data communication.

FIG. 5 is a view showing waveforms detected by a system controller of an apparatus and apparatus for controlling a device using phase angle control communication of an AC power source according to an embodiment of the present invention, and FIG. 6 is an alternating current according to an embodiment of the present invention. A diagram showing waveforms read by a communication receiver of a device control apparatus and method using phase angle control communication of a power supply.

Referring to FIGS. 5 and 6, first, the first control unit 250 stores the first switching signal to the third switching signal, and the first switching signal to the third switching signal are data inputted through the communication unit to an AC power source. In each switching signal corresponding to the start bit, binary 1 or 0 by applying the start bit, binary 1 or 0, the corresponding switching signal is applied to the switching unit according to the input data.

The first switching signal is a signal that is turned off and then turned to an on state, the second switching signal is a signal that is continuously kept in an on state, and the third switching signal is a signal that is turned from an on state to an off state.

In this case, the first switching signal is a state in which the switching signal is turned off only during the cut section by cutting the phase of the start portion based on the first zero voltage point of the AC power, and is turned on again from the uncut section. Waveform.

Since the second switching signal has no phase change with respect to the first zero voltage point of the AC power source, the switching signal is continuously turned on.

Since the switching signal is turned off only during the section cut by cutting the phase of the end of the third switching signal based on the first zero voltage point of the AC power source, the third switching signal is turned on until the section cut from the first zero voltage point. It is turned off in the section, and it is a trailing edge control waveform.

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

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

In this case, the first control unit 250 stores a first switching signal switched from the off state to the on state, a second switching signal maintained from the on state, and a third switching signal switched from the on state to the off state. Each of the switching signal, the second switching signal, and the third switching signal is set to match the start bit or binary 1 or binary 0, respectively.

For example, assuming that the first switching signal is matched to binary 1, the second switching signal is matched to binary 0, and the third switching signal is matched to start bit, the first controller 250 is binary to the communication unit. When 1 is input, the first switching signal corresponding to the binary number 1 is output to the switching unit 240.

The switching unit 240 cuts off the AC power in the OFF state according to the first switching signal, passes the AC power in the ON state, and transmits the alternating AC power generated by applying binary 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 modified AC power and transmits the second zero voltage point signal to the second controller 320.

In this case, the second controller 320 is previously designated a half cycle to be determined based on the second zero voltage point.

For example, when the second controller 320 is specified to be determined based on a half cycle of the modified AC power, the second controller 320 detects the second zero voltage point based on the second zero voltage point when the modified AC power is input. It is judged at the end of the half cycle.

That is, the second controller 320 reads the on-off state every time the modified AC power is input and the second zero voltage point signal is detected, and reads the on-off state at the end of the half cycle to turn the on-off state or It detects whether it remains off or on off and derives each received data packet accordingly.

In addition, the second controller 320 operates only when a switching signal matching the start bit is input based on the second zero voltage point of the modified AC power source. This is to prevent unnecessary operation caused by noise.

For example, in the modified AC power source, when the second zero voltage point signal is turned on from the off state based on the second zero voltage point, the modified AC power source is the data start point.

Hereinafter, the AC controller 20 is input to the system controller 200, the data packet 10100101 is input from an external terminal, and the first switching signal or the third switching signal is matched with binary 1 to the first controller 250. The second switching signal is set to match the binary zero, and the second controller is set to read a half cycle period based on the second zero voltage point as an example.

Referring to FIG. 7, the second control unit 320 recognizes the start bit S as a start, wherein the start bit is changed from the on state to the off state during the half period based on the second zero voltage point. Or the second zero voltage point signal is matched with a switching signal that is switched from an off state to an on state. That is, the start bit corresponds to the trailing edge control waveform or the leading edge control waveform.

Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the off state to the on state, the bit value binary 1 matched with the first switching signal is detected.

Then, in the case where the second zero voltage point signal during the half cycle with respect to the second zero voltage point is kept off, the bit value binary 0 matched with the second switching signal is detected.

Then, in the case where the second zero voltage point signal during the half cycle with respect to the second zero voltage point is kept off, the bit value binary 0 matched with the second switching signal is detected. Then binary 0 is also the bit value from the same process.

Then, in the case where the second zero voltage point signal during the half cycle based on the second zero voltage point is switched from the on state to the off state, the bit value binary 1 matching 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 zero voltage point signal for half a period from the on state to the off state or the on state from the off state based on the second zero voltage point. It is output when switched to. The binary zero is matched with the second switching signal and is output when the second zero voltage point signal is kept off for half a period based on the second zero voltage point.

That is, the start bit corresponds to the leading edge or trailing edge control waveform, and the data to be transmitted is converted into binary so that the remaining phase angle control waveform corresponds to binary 1 or binary 0, and the phase angle is not adjusted. The waveforms are sequentially supplied to correspond to the complementary number (01011010) of the binary number 10100101 value of the waveform whose phase angle is adjusted, thereby serially transmitting the received data packet to the third controller 410.

The third controller 410 receives the received data packet 10100101 read by 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, assuming that the device mode control value is the execution of the operation mode 2, a signal for operating the operation mode 2 corresponding to the received data packet 10100101 is transmitted to the device.

Referring to FIG. 8, the first controller 250 in the system controller 200 according to the present invention includes a switching signal controller 251, a mode data storage unit 252, a power change calculator 253, and a mode learner 254. ), A mode identification unit 255, an abnormality determination unit 256, an input unit 257, and an output unit 258.

The switching signal controller 251 receives the first zero voltage point signal from the first zero voltage detector 230 and receives a data packet through the input unit 257 or the mode learner 254 to provide a data packet to the first zero voltage point. Put on each.

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 converted from an on state to an off state in advance. have.

In this case, the first switching signal or the third switching signal is matched to the start bit, and the other two switching signals except the switching signal matched to the start bit are arbitrarily matched to the binary 1 bit and the binary 0 bit, respectively.

That is, each time the first zero voltage point signal is input, the switching signal controller 251 outputs a corresponding first switching signal, second switching signal or third switching signal to the switching unit 240 according to the data packet.

The power amount change calculation unit 253 grasps the power amount from the power amount detection unit 260 and derives a change in power amount over time based on the detected power amount. According to an embodiment of the present invention, the power amount change calculation unit 253 includes a storage module therein to store the power amount in the past, and derive the change in the power amount by calculating a difference between the power amount of the past and the current power amount. can do.

The mode data storage unit 252 stores power amount data according to an operation mode of a device connected to the system. The power amount data may be directly generated and input by a user or may be stored by the operation of the mode learning unit 254.

The mode learning unit 254 learns the power amount data for each operation mode based on the power amount change information for the operation mode previously executed by the communication unit or the control panel. Alternatively, the operation is tested for all operation modes of all devices, and the power amount data for each operation mode is generated and stored in the mode data storage unit 252 based on the power change information detected during the test. The mode learning method of the mode learning unit 254 will be described later.

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

The abnormality discrimination unit 256 determines an operation mode based on the device mode control value transmitted from the input unit 257, the power amount data stored in the mode data storage unit 252, and the power amount change derived by the power amount change calculation unit 253. Determine if something is wrong. The abnormality discrimination method of the abnormality discrimination unit 256 will be described later.

The input unit 257 receives an external input through the communication unit 210 in the system controller 200 and the panel input unit 610 in the control panel 600, so that the external input is a transmission target data packet indicating a device mode control value ( 10) transmits the transmission target data packet 10 representing the device mode control value consisting of binary 1 bit and binary 0 bit to the switching signal controller 251 and the abnormality determination unit 256, and in the case of the mode learning command. The mode learner 254 transmits the mode learning command.

The output unit 258 may determine whether the operation mode and operation of the device identified according to the operation of the mode identification unit 255 and the abnormality determination unit 256 are abnormal. The display unit 620 in the 600 and / or the abnormality notification unit 630 in the control panel 600 is transmitted.

Referring to FIG. 9, the system controller 200 of the present invention is connected to a plurality of

device controllers

400A, 400B, and 400C, and the device controllers are connected to the

control target devices

500A, 500B, and 500C, respectively.

The plurality of

device controllers

400A, 400B, and 400C are connected in parallel to receive the modified AC power passing through the switching unit 240 of the system controller 200. The modified AC power supply includes information of the transmission target data packet 10 representing the device mode control value.

The device mode control value included in the data packet 10 includes identification information and control information as shown in FIG. 9. The identification information may include a name, a number, an ID, etc. for identifying the control target device 500 or the device controller 400 connected to the device, and the control information includes the control target device 500 according to the identification information. The operation mode control command of may be included.

The device mode control value according to an embodiment of the present invention shown in FIG. 9 includes the name of device 1 (500A) indicating the device to be controlled (500) in the identification information, and the second operation mode of device 1 in the control information. Mode to execute 1-2 Contains the ON instruction. Hereinafter, the n-th operation mode of the m-th device will be indicated by the mode m-n. The operation mode may vary depending on the type of device. When the control target device is a light, the operation mode can be set to Mode 1, Mode 2, and Mode 3 for the three modes of OFF, DIM, and BRIGHT according to the brightness of the light. The operation modes may be set to Mode 1, Mode 2, Mode 3, and Mode 4 for the four modes of OFF, LOW, MID, and HIGH, respectively.

As shown in FIG. 9, when the system controller 500 of the connected system transmits the modified AC power including the data packet including the device mode control value, the plurality of

device controllers

400A, 400B, and 400C connected thereto are the same. A modified AC power supply is received and the same data packet is restored based on this. Thereafter, the second controller 320 in the device controller receives the identification information of the device mode control value from the data packet and compares the identification information with previously stored identification information, and only when the received identification information and the previously stored identification information are the same. Therefore, the connected device is controlled.

As illustrated in FIG. 9, when the identification information of the device mode control value includes the device 1 information, the device 1 controller 400A controlling the device 1 500A may identify the identification information of the device mode control value and the previously stored identification. After confirming that the information is the same, the device 1 (500A) is operated in the mode 1-2 according to the control command included in the control information. On the other hand, the device 2 controller 400B and the device 3 controller 400C controlling the device 2 500B and the device 3 500C, respectively, are different from the previously stored identification information. It will be ignored without control command.

Through such identification information, it is possible to select a specific device controller 400A connected to the device 500A to be controlled from the plurality of

device controllers

400A, 400B, and 400C connected in parallel, and control the same.

However, the present invention includes not only a system having a plurality of devices as shown in FIG. 9 but also an embodiment in which there is a single device and controls the operation of the single device and identifies its operation mode.

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

10A illustrates an embodiment of a mode learning method.

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

Next, the power amount detection unit 260 detects the current power amount (S21).

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

Next, the power amount change calculation unit 253 calculates the power amount change by comparing the power amount detected in step S21 with the power amount detected after step S22 (S23).

Next, the mode learning unit 254 transmits the device mode control value for terminating the mode m-n to the switching signal controller 251, so that the device m ends the mode n (S24).

Next, the mode learning unit 254 stores the amount of power calculated in S22 for the mode m-n in the mode data storage unit 252 (S30).

Next, the mode learning unit 254 increments the counter n by one (S40).

Next, the mode learning unit 254 checks whether the internal counter n exceeds n _m (S50). In this case, n _m is a number previously stored in the mode learning unit 254, and is the number of operation modes in which the device m may operate.

If the counter n does not exceed n _m , go back to step S21 and repeat the step of calculating and storing the change in power for n.

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

Next, the mode learning unit 254 checks whether the internal counter m exceeds m _s (S70). At this time, m _s is a number pre-stored in the mode learning unit 254 and is the number of devices connected to the system.

If the counter m does not exceed m _s , go back to step S21 and repeat the step of calculating and storing the power change for m.

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

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

According to an embodiment of the present invention, preferably, in step S21 to S24, a mode data storage unit by setting the representative value of the power change calculation value data obtained by repeatedly executing a predetermined number of times as the power amount of the operation mode; 252 may be stored. Through such repetitive execution, it is possible to exert an effect that more accurate power amount data can be constructed.

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

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

Then, 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 through the communication unit 210 or the panel input unit 610 from the input unit 257 ( S120).

Next, the switching signal controller 251 generates a switching signal, and the switching unit 240 generates a modified AC power according to the switching signal, and receives the mode mn by the device controller 400 receiving the modified AC power. This is executed (S130).

Next, the power amount change calculation unit 253 calculates the power amount change by comparing the power amount detected in step S110 with the power amount detected after step S130 (S140).

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

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

The mode identifying unit 255 may identify 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 change in power amount derived by the power amount change calculation unit 253. Know the current mode of operation.

To this end, the mode identification unit 255 receives a change in power amount from the change amount calculation unit 253 whenever the change in amount of power derived by the change amount calculation unit 253 is not 0, and thus the change amount value and the mode. By comparing the amount of power data for the operation mode stored in the data storage unit 252, the change of the operation mode is grasped and stored.

Thereafter, the mode identification unit 255 transmits the identified change of the operation mode 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 the received change of the operation mode to the external management device through the external communication network 30, and the display unit 620 outputs the received change of the operation mode to the device.

As described above, the operation mode is identified whenever the change in power amount calculated by the power change calculation unit 253 is not zero, i.e., whenever the amount of power changes, so that the device is controlled by the system controller 200. Even when the device is directly controlled and the mode is changed, it is possible to identify a change in the operation mode accordingly, and by transmitting 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 check the operation mode. That is, through the operation of the mode identification unit 255, it is possible to achieve the effect of receiving the feedback of the operating state of the connected device 500 under the phase angle control communication of the AC power that can transmit data only in one direction.

12 and 13 are diagrams schematically illustrating a mode identification 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.

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

The power amount change calculation unit 253 derives a power amount change value with time of the power amount detected by the power amount detection unit 260. The derived change amount of power 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 and finds a value within the same or an error range, and the operation mode corresponding thereto. Extract

According to the embodiment shown in FIG. 12, the power amount change value derived by the power amount change calculation unit 253 is +44 kW, and when compared with the power amount data stored in the mode data storage unit 252, the power amount change value and the error are determined. It is possible to extract mode 2-1 in range, indicating that the second device in the system has initiated the first mode of operation. 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 change in power amount is -44 kW, it may be determined that the operation mode is terminated, not the start of the operation mode.

Thereafter, the mode identification unit 255 may transmit the change of the identified 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, the power amount change value derived by the power amount change calculation unit 253 is +92 kW, and when compared with the power amount data stored in the mode data storage unit 252, the power amount change value and the error are determined. Mode 1-3 and mode 2-2 within the range can be extracted. As such, when the amount of power data of two or more operation modes are the same or similar, the operation mode cannot be identified only by the change in the amount of power.

In this case, the mode identification unit 255 may identify the operation mode by controlling the operation mode of the device 500 connected to the system.

If the mode identification unit 255 cannot identify the operation mode based only on the change in power amount, the mode identification unit 255 performs a test for transmitting an end command after starting operation for all operation modes of all devices connected to the system, and detects the amount of power during the test. The change information is compared with the amount of power data stored in the mode data storage unit 252 to detect an operation mode that does not match the data.

13, when the operation mode of the actual system is 2-2, when the mode identification unit 255 transmits an end command after the operation of the mode 1-3 starts, it is stored in the mode data storage unit 252. As with the power amount data, the power amount increases by 90 kW and then decreases by 90 kW. On the contrary, when the mode identification unit 255 transmits a termination command after the operation of the mode 2-2 starts, the mode 2-2 is already in operation, and thus only 90 kW is reduced without increasing the amount of power. At this time, the mode identification unit 255 identifies the operation mode as the mode 2-2, and gives the operation start command of the mode 2-2 again to operate the terminated mode 2-2 again.

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

Alternatively, if the operation mode of the device connected to the system operates exclusively with other operation modes, for example, when Mode 1-2 operates, Mode 1-1 and Mode 1-3 terminate, By testing only one mode, you can identify the device that was running and identify the operating mode.

13, when the operation mode of the actual system is 2-2, when the mode identification unit 2550 transmits an end command after the operation of the mode 1-1 starts, the mode data storage unit 252 stores the mode data storage unit 252. As with the power amount data, the power amount increases by 30 kW and then decreases by 30 kW. On the contrary, if the mode identification unit 255 transmits a termination command after the operation of the mode 2-1 starts, the mode 2-1 starts and the mode 2-2 ends at the same time because the mode 2-2 has already been operated. As a result, the amount of power is reduced by 45 kW and as the mode 2-1 ends, the power is reduced by 45 kW. At this time, the mode identification unit 255 identifies the operation mode as the mode 2-2, and gives the operation start command of the mode 2-2 again to operate the terminated mode 2-2 again.

After identifying the operation mode of the system as described above, the mode identification unit 255 may 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 an embodiment of the present invention by the operation of the mode identification unit 255 as described above, in addition to the case where the device is controlled by the system controller 200, the device is directly controlled by the user and the mode is changed. In this case, a change in the operation mode may be identified, and the manager of the system controller 200 may operate by transmitting the identified operation mode to the communication unit 210 or the display unit 620 through the output unit 258. You can check the system for integrated management and monitoring of the entire system. That is, through the operation of the mode identification unit 255, it is possible to achieve the effect of receiving the feedback of the operating state of the connected device 500 under the phase angle control communication of the AC power that can transmit data only in one direction.

The abnormality determining unit 256 checks the operation state of the device connected to the system to determine whether the abnormality is detected, 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 electric power change calculator. The abnormality of the operation mode is determined based on the change.

To this end, whenever the abnormality determination unit 256 receives the device mode control value from the input unit 257, the device mode control value, the power amount change value derived by the power amount change calculation unit 253, and the mode. The abnormality is determined based on the power amount data for the operation mode stored in the data storage unit 252.

When the abnormality determining unit 256 receives the device mode control value from the input unit 257, the control unit extracts the control information included in the device mode control value, and compares the extracted control information, power change value, and power amount data. It is determined whether the operation mode according to the control information changes without error. Through this, it is possible to determine the operation state of the connected device 500 under the phase angle control communication of the AC power, which can transmit data only in one direction, and receive feedback on the abnormality.

The abnormality determination unit 256 may directly determine whether the abnormality is based on the device mode control value, the power change value, and the power amount data. However, the mode identification unit 255 may derive the power based on the power change value and the power amount data. The abnormality may be determined based on the operation mode. In this case, the abnormality determining unit 256 compares the device mode control value received from the input unit 257 and the operation mode received from the mode identifying unit 255 to determine whether there is an abnormality.

After that, when there is an abnormality in the operation mode, the abnormality determining unit 256 displays the display unit 620 and the abnormality notification unit of the communication unit 210 and the control panel 600 of the system controller 200 through the output unit 258. Transmit to unit 630. The communication unit 210 transmits the received abnormality to the external management device through the external communication network 30, the display unit 620 outputs the abnormality to the device, and the abnormality notification unit 630 is sound or It is possible to indicate whether an abnormality through the warning light.

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

The abnormality determining unit 256 receives the device mode control value from the input unit 257 and extracts control information from the device mode control value.
