As shown in FIG. 1, power through phase control for an infrared remote controller 10 having an infrared transmitter so as to remotely control one or more channels and any channel selected according to the operation of the infrared remote controller 10. It consists of a multi-channel switch module 100 for controlling one or more drive means in a control manner.

Here, the remote control is described as using the infrared method in the present invention, of course, the remote control using the RF method can be applied, in this case, instead of the infrared signal receiver 112 to be described later can receive the RF signal. Module must be fitted.

Subsequently, the multichannel switch module 100 includes; Infrared signal receiver 112 receives a predetermined selection signal for a certain channel from the infrared remote controller 10, receives a selection signal from the infrared signal receiver 112, and zero crossing of the zero crossing detection unit 116. A microprocessor 114 for generating a PWM (Pulse Width Modulation) phase control signal according to a control pulse signal input based on the control signal and a control switch 118 for directly applying a control signal separately from the infrared remote controller 10 are provided. A power control processor 110; The power filter unit 122 for removing noise of the commercial AC power applied from the outside, the AC power output from the power filter unit 122 is first converted down and the converted power is zero crossing detection unit 116. Transformer 124 for supplying the power to the transformer, a constant voltage supply unit 126 for converting the primary converted power from the transformer 124 to the secondary power and supplying the driving power to the microprocessor 114, and the power filter unit 122 is a power supply provided with one or more phototriacs (up to three in the present invention) 128 for switching and receiving a PWM phase control signal output from the microprocessor 114 while receiving AC power supplied from the microprocessor 114? It is composed of a switching unit 120.

The microprocessor 114 receives and stores a multi-channel switching program that can be controlled in a custom order. The program is a key operation for controlling the driving means according to the key operation applied from the infrared remote controller 10 and the control switch 118, for example, power on / off and on / off control of the phototriac 128. And stored. The key operation setting is provided with an ISP (In System Promrammer) function that can be changed and upgraded according to the type of driving means. As the microprocessor 114 in the present invention, 'AVR 90s2313' is adopted, and a flash memory or the like is usually mounted.

In addition, the multi-channel switching program stores a timer program (not shown) for controlling the phototriac 128 on / off at a predetermined time according to the operation of the infrared remote controller 10. The time setting through the timer program may be set through various keys provided in the infrared remote controller 10 and the control switch 118.

The zero crossing detection unit 116 detects a zero crossing time point of the AC power delivered from the transformer 124 and generates a control pulse signal when the AC power crosses the zero point.

The power filter 122 is a power filter composed of a reactance (L) and a capacitor (C).

The transformer 124 down-converts the commercial AC power supply 220V to an 8V AC power, and provides the zero crossing detecting unit 116 and the constant voltage supply unit 126, and the constant voltage supply unit 126 is the transformer 124. The 8V AC power outputted by the converter is converted into a 5V DC power and supplied to the driving power of the microprocessor 114.

The phototriac 128 is a type in which the photocoupler and the triac are manufactured in one IC form, and control the bidirectional operation of the electrical insulation and the triac. In the present invention, three phototriacs 128a to 128c are provided. To control the on / off driving of the lamp 130a, the AC single-phase motor 130b, and the heating wire 130c as the driving means described later. Of course, the driving means can be changed according to any device to which the multi-channel switch module 100 is applied and driven.

In addition, the infrared signal receiving unit 112 is applied to the infrared receiving sensor that can minimize the influence from the external environment such as light, the infrared receiving sensor is a filter circuit and software for stabilizing the operation of the infrared remote control 10. This provides an algorithm that is resistant to noise.

Meanwhile, as shown in FIG. 2, the multi-channel switch module 100 is mounted in the indoor lighting fountain 200 and remotely controls the driving means according to the operation of the infrared remote controller 10 or the multi-channel switch module. It is configured to be able to control by operating the control switch 118 provided in the (100).

In the embodiment of the present invention, the multi-channel switch module 100 is limited to being mounted and driven in the indoor lighting fountain 200, but other devices capable of remote control (AC power supply, home automation), sealing fan speed Of course, it can be applied to control, living room indoors and the like.

The multi-channel switch module 100 having the above configuration is designed as a small printed circuit board (PCB) to be installed in the indoor lighting fountain device (200).

Reference numeral 210 is a surface provided so that the water stored in accordance with the operation of the AC single-phase motor 130b flows from the upper direction to the lower direction.

Next, the operation of the present invention configured as described above will be described with reference to the drawings.

First, the multi-channel switch module 100 is miniaturized to a printed circuit board and mounted at a predetermined position in the indoor lighting fountain 200, and the first to third phototriac provided in the multi-channel switch module 100 The on / off times of 128a to 128c are set by the microprocessor 114 on the basis of the zero crossing time of the AC power supply.

At present, the AC power of the Republic of Korea is 60 kW, and since zero crossing is repeatedly generated every 8.33 kW, which is a half cycle period of 16.66 kW, the gate applied to the phototriacs 128a to 128c in the 8.33 kW cycle. By varying the timing of the generation of the pulse signal, it is possible to control the power of AC power.

Accordingly, as described above, the microprocessor 114 may control the first to the second signal according to the selection signal applied by the operation of the infrared remote controller 10 or the control switch 118 and the control pulse signal applied from the zero crossing detecting unit 116. The data programmed to output the PWM phase control signal for controlling the third phototriacs 128a to 128c is prestored and stored in a custom manner.

From such a state, the user can operate the infrared remote controller 10 or the control switch 118 to control the on / off control and the driving means 130a to 130c associated with the phototriacs 128a to 128c. I will continue to explain this.

First, when the indoor lighting fountain device 200 equipped with the multi-channel switch module 100 receives a commercial AC power supply of 220V, it maintains a standby state, and for supplying power to the infrared remote controller 10. When the key is manipulated, the AC power is supplied to the power switching unit 120, and line noise is removed by the power filter unit 122 and then transferred to the transformer 124 for power conversion.

The transformer 124 first converts the commercial AC power supply 220V into an AC power supply 8V, and then supplies it to a zero crossing detection unit 116 that detects a zero crossing point of the commercial AC power supply, and further, the microprocessor 114. The supply voltage is supplied to the constant voltage supply unit 126 so as to supply an operating voltage of 5 V to the bridge circuit (not shown) and the DC power converted by the constant voltage regulator.

In the state where power is supplied to the multi-channel switch module 100 as described above, when the user manipulates the key for driving the lamp 130a in the infrared remote controller 10, the lamp selection signal is spaced a predetermined distance apart. The infrared signal receiver 112 is supplied to the microprocessor 114.

In this case, the microprocessor 114 receives a control pulse signal from the zero crossing detection unit 116, and the control pulse signal is an AC power output from the transformer 124 by the zero crossing detection unit 116. A zero point is detected and provided to the microprocessor 114 when the AC power crosses the zero point.

Then, the microprocessor 114 determines the zero crossing time of the AC power according to the detection result of the zero crossing detecting unit 116 and according to the selection signal transmitted from the infrared remote controller 10, the first phototriac. A phase control signal for turning on 128a is output.

The pulse width modulation (PWM) method is used for the phase control signal to minimize the stress of the power device and to efficiently control the power. When the phase control signal is generated at the time of zero crossing of the AC power supply and provided to the gate terminal of the first phototriac 128a, the first phototriac 128a is turned on and the lamp 130a is turned on. .

At this time, the microprocessor 114 can be controlled by defining the amount of illumination and the lighting time, the lighting time, etc. of the lamp in advance by the program setting.

Similarly, the user may drive the AC single-phase motor 130b to supply water stored in a predetermined place in the fountain 200 through the water supply device, and then may be remotely controlled to flow along the outer surface 210.

This is a control pulse generated when the user operates a specific key of the predefined infrared remote controller 10, the microprocessor 114 passes the zero point from the zero crossing detection unit 116 to determine the zero crossing point. The second phototriac 128b is turned on by outputting a phase control signal according to the key operation according to the signal.

Then, the AC single phase motor 130b is driven by the conduction of the second phototriac 128b, and the stored water is driven to the upper end of the indoor lighting fountain 200 according to the driving of the AC single phase motor 130b. After being pulled up, it flows along the outer surface 210.

Thereafter, when a selection signal for turning off the AC single-phase motor 130b is transmitted to the microprocessor 114 according to a key operation of the infrared remote controller 10, the microprocessor 114 is similarly phased at the time of zero crossing. The control signal is transmitted to the gate terminal of the second phototriac 128b to turn off the second phototriac 128b.

In addition, the process of driving the driving means by turning on the third phototriac 128c is performed in the same manner as the control process of the first phototriac 128a and the second phototriac 128b.

As such, when the user arbitrarily manipulates predetermined keys of the preset infrared remote controller 10, the microprocessor 114 outputs phase control signals for controlling the phases of the driving means 130a to 130c at zero crossing time, respectively. In addition, the driving means 130a to 130c can be remotely turned on and off according to the driving of the phototriacs 128a to 128c receiving the phase control signal.

In addition, the user may directly operate the control switch 118 without using the infrared remote controller 10 to drive the lamp 130a and the AC single-phase motor 130b. When an operation of the control switch 118 occurs, the microprocessor 114 conducts the first to third phototriacs 128a to 128c and controls the driving means 130a to 130c. Since the processing is performed in the same manner as in the operation of 10), the description thereof will be omitted.

On the other hand, by operating the infrared remote controller 10 or the control switch 118, the phototriac (128a ~ 128c) can be turned on and off at a predetermined time by setting the time of the timer program.

The timer program is 30 minutes, 1 hour, 1 hour 30 minutes,… according to the user setting. Since the time can be set to a predetermined unit time, such as, when the second phototriac 128b is to be turned off 1 hour after the on-drive through the key manipulation of the infrared remote controller 10, If you operate twice, one hour is set and the setting completion can be confirmed through a separate indicator (not shown).

Accordingly, after the time is set, the microprocessor (after 1 hour has elapsed while the second phototriac 128b is turned on to drive water along the outer surface 210 as described above). 114 controls the timer program to turn off the phototriac 128b so that the water supply is stopped.

In addition, after setting the off time as described above, the corresponding driving means may be continuously operated by removing the set off time. When the corresponding key of the infrared remote controller 10 is operated, the microprocessor 114 may operate the key. The timer program is controlled to release the set time and return to the initial state. Then, the driving means, for example, the second phototriac 128b is continuously turned on until a separate control signal is generated.

As described above, according to the present invention, an electromagnetic wave path is connected between an infrared sensor constituting the infrared signal receiver 112 of the multi-channel switch module and a PCB (printed circuit board) connector pin with a shielding wire, which is an electromagnetic shielding wire. It is possible to prevent the malfunction of the switch module.
