The switch controller 140 generates a command for controlling the electronic device 120 as a logic control signal of a high or low logic level by generating a switching control signal for a logic signal of high or low according to an embodiment of the present invention. When a zero voltage is sensed at a voltage input from the power supply unit to the switch 130, the switching control signal of the logic signal high remains the switch 130 in the switched on state, The switching control signal of the logic signal low switches off the switch 130 and the electronic device 120 recognizes that the operation is performed by recognizing the switching on / off operation of the switch 130 as a logic signal .

The switch controller 140 and the switch 130 may be implemented in separate configurations, or may be implemented in one configuration.

In the electronic device control apparatus using the power line switching logic according to an embodiment of the present invention, the electronic device 120 recognizes the logic signal high when the switch 130 is in the on state at zero voltage , And when the switch 130 is in the switching off state at the zero voltage, it is recognized as a logic signal low so that the operation is performed.

In the electronic device control apparatus using the power line switching logic according to the embodiment of the present invention, the switch 130 receiving the switching control signal of logic signal low from the switch controller 140 switches the electronic device 120 (The threshold time Tc) that does not affect the normal operation of the semiconductor memory device.

The threshold time Tc of the switch 130 is as short as possible for a prescribed time or at a level that does not affect the normal operation of the electronic device 120 and can be determined by the characteristics of the electronic device 120 .

In the electronic device control apparatus using the power line switching logic according to an embodiment of the present invention, the switch controller 140 switches the logic signal row so that the switch 130 can be switched off only during the critical time Tc. And outputs a switching control signal of a logic high signal immediately at a critical time after outputting the control signal, which is performed by the unique sequence control according to an embodiment of the present invention It will be possible.

The switch controller 140 includes a first zero voltage detector 141 for detecting a zero voltage of an AC input voltage, a second zero voltage detector 141 for detecting a zero voltage of the AC input voltage, And a master MCU 142 for outputting a logic signal for switching control of the switch 130 to the switch 130 on the basis of an AC zero voltage detected by the zero voltage detecting unit 141 .

In the electronic device control apparatus using the power line switching logic according to an embodiment of the present invention, after the master MCU 140 outputs the switching control signal of the logic signal row, whether the switch 130 is normally switched off And further includes a feedback unit 162 provided at a rear end of the switch 130 for verification.

1, the switch controller 140 receives a current sense signal from the current sensor 162, and the state before the command And if there is no change, it automatically repeats transmission.

The function for detecting the current change is to redo the drive command if there is no change in the current value and to improve the error by repeating twice.

The amplifying unit 164 amplifies the current sensed by the current sensor 162 and outputs the amplified current to the switch controller 140.

The feedback unit 162 may be constituted by a voltage sensor (not shown) as a configuration to be replaced with the current sensor 162.

In the electronic device control apparatus using the power line switching logic according to an embodiment of the present invention, the electronic device 120 may further include a second zero voltage detecting unit 121 for detecting a zero voltage at the end of the switch 130, Off state of the switch 130 through a voltage signal inputted through the second zero voltage detecting unit 121.

(The polling zero voltage F0 and the rising zero voltage R0) in the slave MCU 122 and the electronic device 120 recognizes the delay time difference of the zero voltage as the logic signal high [logic signal 1] And low (logic signal 0), and outputs the operation control signal as a logic signal.

Now, the logical control sequence of the master MCU 140 and the slave MCU 122 will be described in detail.

In the apparatus for controlling an electronic device using the power line switching logic according to an embodiment of the present invention, when the first zero voltage detector 141 detects a falling zero voltage F0 (when the voltage value falls to " 0 " Voltage value immediately before V], it outputs a trigger signal to the master MCU 140. [

The master MCU 140 receiving the trigger signal from the first zero voltage detector 141 outputs a logic signal to the master MCU 140 when the master MCU 140 outputs a logic signal low command, To the switch 130, and the switch 130 receiving the switching control signal of the logic signal row is switched off.

When the switch output voltage exceeds the zero voltage and the current value received from the feedback unit 162, for example, the current sensor 162 is zero (strictly speaking, the master MCU 140 outputs a rising zero voltage R0 ) [The voltage value immediately after the voltage value exceeds 0 V]}, the switching control signal of the logic signal high is outputted, and the switch 130 receiving the switching control signal returns to the switching on (0N).

In the electronic device control apparatus using the power line switching logic according to an embodiment of the present invention, the slave MCU 122 receives the polling zero voltage F0, the rising zero voltage (Logical value 1 or logic value 0) and stores the logical value by monitoring the average time of the time of the input signal R0 and storing the average time.

On the other hand, the switch controller 140 is provided with an address setting unit (not shown) for designating an address to a plurality of electronic apparatuses 120 and an address canceling unit May be included.

An address is automatically designated when an address of an electronic device 120 to which an address is to be designated is turned on and a switch corresponding to the addressing mode of the switch controller 140 is turned on, Reset), only the electronic device to be reset is turned on, and the address is automatically released if the address switch releases the drive switch.

A plurality of the electronic devices (120) are connected in parallel.

According to this, the electronic device 120 can control a plurality of N (one or more natural number) electronic devices 120 in parallel. At this time, the electronic devices 120 may have the same characteristics or different characteristics.

In the apparatus for controlling an electronic device by power line switching logic according to an embodiment of the present invention, the switch 130 is a large-power non-contact switch element and is connected to the non-contact switch element, And a loss reduction switch 135 for reducing the loss of the input signal.

According to this, there is an advantage that the current can flow toward the loss reduction switch 135, thereby reducing the power loss. That is, in the case of large power, since the power loss in the switch 130 is very large, there is an advantage that it can be prevented.

One electronic device 120 may be a single electronic device or a group of a plurality of electronic devices.

That is, in the electronic device control apparatus by the power line switching logic according to the embodiment of the present invention, the electronic apparatus to be controlled may be provided with a plurality of electronic apparatuses so as to individually control the plurality of electronic apparatuses, Groups of electronic devices may be grouped and controlled in groups.

The electronic device may or may not have its own power switch. In this description, the case where the power switch is provided is taken as an example. In the case of the electronic device without the power switch, the power connection and disconnection are the same as the switch on and off.

When an arbitrary designated group or individual electronic device is connected and the power switch of the electronic device is turned on and the address setting unit of the switch controller 140 is selected and an arbitrary designated number of switches is turned on, (For example, 4Bits 1) 0001 is assigned by the switch. Then, the arbitrary designated group or the individual electronic device in which the power switch is turned on is assigned the same one address at the same time.

In this same way, all electronic devices can be addressed identically or differently.

If it is necessary to release the predefined address, the address is deleted when the designation button is turned on after selecting the address release unit. Then, when redesigning, it is repeated as described above.

The following describes a specific method of controlling the electronic apparatus by switching based on Fig.

When an instruction (for example, brightness control, on-off, etc.) is inputted from the command input unit 150, the switch controller 140 generates a switching control signal of logic signal high or low based on the inputted command.

In the case of the switching control signal of the logic signal high, the switch 130 outputs the switching control signal of the logic signal high so that the switch 130 remains in the switching-on state.

3, the switching control signal of the logic signal line is outputted for a very short time, for example, the critical time Tc at the zero voltage point, so that the switch 130 is switched Off state.

When the switch 130 is switched by the switching control signal received from the switch controller 140, the slave MCU of the electronic device 120 recognizes the switching state of the switch 130 as a logic signal.

As shown in FIG. 3, the slave MCU of the electronic device 120 recognizes the logic 130 as a logic signal low when the switch 130 is in the off state and recognizes it as the logic high when the switch 130 is in the on state.

Therefore, as shown in FIG. 3, since the switch 130 has an off-time of five times, the MCU of the electronic device recognizes 8-bit digital data of 010001011.

Meanwhile, in the electronic device control device by the power line switching logic according to the embodiment of the present invention, the electronic device corresponds to any electronic device in which a programmable slave MCU 122 can be embedded, for example, an LED .

When the electronic device is an LED lamp, the control operation may be, for example, brightness, color, and on / off control.

The master MCU 142 built in the switch controller 140 and the slave MCU 122 built in each electronic device 120 are programmed with logic for various defined control. Accordingly, various commands such as ON / OFF, dimming, and lighting color change of the LED lamp are transmitted to the corresponding LED lamp through the switch controller 140 and controlled through the remote controller or the manual operation .

The present invention can be applied to all electronic apparatuses provided with a slave MCU 122 for receiving and receiving a commercial power supply via a power line, and accordingly, the on / off (ON / OFF) It can be applied to any command that is required for control, and its application range is very wide.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is self-evident to those who have.

Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
