BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to the use of pre-installed switch wiring in controlling electrical equipment such as lighting lamps and sealing fans. In particular, the present invention relates to electrical equipment such as ceiling lighting lamps and sealing fans only by operation of switches attached to walls. The present invention relates to a controller using an AC power switch wire so that the user can conveniently control the user's convenience and use existing switch wiring as it is.

Looking at the method of controlling the ceiling lamp according to the prior art with reference to Figure 1 as follows.

The first feature of the controller using the AC power switch line according to the present invention for solving the above problems is a power switch to generate and output a control signal according to the user's operation while supplying power to the electrical equipment and from the power switch A pulse signal generator for generating a pulse signal corresponding to the control signal from the power switch in order to control the electric device as desired by the user by receiving the control signal, the pulse signal generated by the pulse signal generator to control the input of the microcomputer A signal detection unit for extracting a signal corresponding to a condition, a control micom for receiving a signal from the signal detection unit and outputting a device control output, a driving circuit unit for generating a device driving output from the device control output from the control micom, and each unit Including a controller configured as a power supply unit for supplying power to the .

In addition, according to the second aspect of the present invention, the power switch is connected to the main switch (SW0) and the coil (L) in series, and then the coil again in parallel with the first touch switch (SW1) and the coil (L) In addition, the diodes D0 are connected in series to the second touch switch SW2 in parallel.

According to a third aspect of the present invention, the pulse signal generator of the controller does not generate a pulse signal when the first touch switch SW1 connected in parallel with the coil L of the power switch is turned on. When only the second touch switch SW2 connected in parallel through the coil L and the diode D0 is turned on, a pulse signal corresponding to a power frequency is generated, and both the first and second touch switches are turned off. When generated, generate a pulse signal twice the frequency of the power supply frequency.

Hereinafter, with reference to a preferred embodiment of the present invention (an embodiment to a sealing fan light) will be described in detail.

Referring to FIG. 2, when the main switch SW0 is turned on, power is applied to the electric device through the coil L and the switch wiring so that the microcomputer 40 of the controller 200 enters a standby state. In this state, the operation of the first touch switch SW1 will first be described. When the first touch switch SW1 is input once, the microcomputer 40 detects this and turns on both the first lamp LAMP1 and the second lamp LAMP2 as shown in FIG. 3. Next, when the first touch switch SW1 is input one more time (second time), the microcomputer 40 detects this and turns off the first lamp LAMP1 and turns on the second lamp LAMP2. . In this state, when the first touch switch SW1 is input one more time (three times), the microcomputer 40 detects this and turns off both the first lamp and the second lamp. As described above, each time the first touch switch SW1 is input (ON) while the main switch SW0 of the power switch 100 is turned on, the microcomputer 40 of the controller turns on the lamp.

Control to work in order. The recognition of the input of the first touch switch SW1 by the microcomputer determines whether the pulse is present, and if there is no pulse, the first touch switch SW1 is recognized as ON. This is because the pulse generator 20 does not generate a pulse when the first touch switch SW1 is input ON.

Next, the operation of the second touch switch SW2 will be described. The second touch switch SW2 is a switch connected in series with the half-wave diode D0 and then connected in parallel with the coil L. When the main switch SW0 is turned on and the second touch switch SW2 is input once with the power supplied to the electric device, the microcomputer 40 detects this and controls the motor driving circuit. As shown in FIG. 4, the sealing fan motor is rotated at three speeds (high speeds). When the second touch switch SW2 is input twice, the microcomputer 40 controls the sealing fan motor to rotate at two speeds (medium speed). When the second touch switch SW2 is input three times (ON), the microcomputer 40 controls the sealing fan motor to rotate at a single speed (low speed). In this case, when the second touch switch SW2 is turned on again (four times), the microcomputer 40 turns off the sealing fan motor. As described above, whenever the second touch switch SW2 is input while the main switch SW0 of the power switch is ON, the control micom 40 operates the sealing fan motor.

Control to rotate in the order of.

The microcomputer 40 recognizes the input ON of the second touch switch SW2 by determining the presence or absence of a pulse (60 Hz pulse) having the same frequency as the power frequency, and if there is a pulse of the power frequency (60 Hz pulse), It is recognized that the touch switch SW2 is ON. This means that the pulse generator 20 generates a pulse having a power frequency of 60 Hz when the second touch switch SW2 is ON. Because.

Looking at the pulse generation frequency of the pulse generator according to the switch input (ON) of the power switch 100 that operates as described above

As shown in FIG. 1, when the first and second touch switches SW1 and SW2 of the switch 100 are both turned off, the current supplied to the device is supplied through the 100% coil L. As shown in FIG. Therefore, the current flowing in the coil L is changed in direction at intervals of 120 times / second, and the pulse generator 20 of the controller changes the counter electromotive force induced in the coil L whenever the current flowing in the coil L is changed. Since pulses are generated by using the pulses, the pulses are generated at twice the frequency (120 Hz). In addition, when the first touch switch SW1 is turned on, since a considerable current flows through the first touch switch SW1, the force of the counter electromotive force induced in the coil L is very weak. 20 does not generate a pulse.

On the other hand, when the first touch switch SW1 is OFF and the second touch switch SW2 is ON, current flows through the half-wave diode D0, and the current flows only through the coil L (100). %) Since a pulse is generated when it is about to flow, the pulse signal generator 20 of the controller 200 generates a pulse having the same frequency (60 Hz) as the power frequency.

The pulse signal generator 20 generating the pulse signal as described above includes first and second capacitors C1 and C2, a bridge rectifier 21, and a first resistor R1.

Meanwhile, the fuse F, the first and second and third capacitors C1, C2 and C3, the bridge rectifier 21, the first to third resistors R1, R2 and R3, the transistor TR and the zener The diode D1 serves as a power supply unit 50 for supplying the DC power required for each part of the controller. The signal detection unit including the fourth and fifth capacitors C4 and C5, the fourth and fifth resistors R4 and R5, and the second to fourth diodes D2, D3, and D4 is provided by the pulse signal generator 20. From the generated pulse signal, a signal of a certain voltage that can be recognized by the microcomputer 40 is generated and applied to the control signal input terminal IN of the microcomputer 40 so that the microcomputer 40 can recognize the control signal. To perform. The lamp driving circuit 61 drives the first lamp and the second lamps LAMP1 and LAMP2 according to the lamp control signal outputs OUT1 and OUT2 from the microcomputer 40, and the motor driving circuit 62 performs the above operation. According to the sealing fan motor control output signals OUT3 and OUT4 from the microcomputer 40, the motor speed is controlled or the motor is turned off.

As described above, the operation principle of the preferred embodiment of the present invention has been described with reference to FIGS. 2, 3, and 4. Although the embodiment of the composite product of the sealing fan and the lighting has been described, the controller using the AC power switch line of the present invention can be applied to all the electric devices used by connecting the electric device and the power switch through the wiring.

The controller using the AC power switch wire of the present invention configured as described above transmits power and control signals at the same time through the power switch wiring, so that the electrical equipment is already switched wiring such as a sealing fan or a lighting for a house. When applied, the installation and configuration of electrical equipment is simple and easy to use, which can increase the price competitiveness of the product.
