The present invention relates to a wireless and touch lighting switch device capable of combining a wireless method and a touch method, and more particularly, not only is not affected by the operation of the AC load, but also does not affect the operation of the AC load. The present invention relates to a wireless and touch light switch device designed to stably supply DC power and determine whether a load is operated.

In general, in the case of a light switch installed on a wall of a home or office, since the power wiring is connected to the fluorescent lamp (lamp) by a wired method, the fluorescent lamp is turned on according to the on / off of the light switch. It is made to be extinguished.

1 is a circuit diagram showing a DC power supply in the conventional wireless light switch device. Here, the DC power supply unit of the wireless lighting switch device is composed of a voltage drop circuit including a typical transformer and bridge rectifier circuit and a switch device for switching lighting.

As shown in this configuration, standby power is consumed even when the power supply is turned off, and the equipment is composed of two circuits which are reversed to the common use of the apparatus in three circuits.

Therefore, in order to install the conventional wireless light switch, a separate DC power wiring and power piping work had to be preceded on the wall, and power was required according to the on / off operation of the light switch.

The lighting fixtures installed in each room in the conventional building are each supplied with power through the power wiring, and are connected to each lighting fixture through the light switch and the power wiring so that the light fixture is turned on or off according to the input state of the light switch. .

For this reason, the lighting switch is arranged one-to-one through the light fixture and the power wiring, which is inconvenient to change the connection state of the power wiring whenever the lighting fixture is added or the arrangement state is changed.

In addition, the power wiring between the lighting fixture and the light switch is confused or peeled off so that the input state of the switch is not properly understood or the user's command is not correctly transmitted.

In order to solve the problems of the conventional light switch, it is proposed that the signal can be sent and received wirelessly between the light switch and the light fixture, two or more of them will be described.

Korean Patent No. 007068 is a case where a wireless switch is used, and when a device such as a remote controller is used as a switch, problems such as an increase in wiring cost can be reduced, thereby increasing the number of switches flexibly and realizing it to some extent. However, in order to solve the problem of increasing the operation cost of the switch due to an increase in power supply (for example, a remote control battery) and replacing the battery after a certain period of use, the switch has a series of switches. In addition to inducing them to generate their own driving voltage through the electromagnetic induction method, and to selectively turn on / off the lights associated with them through a series of wireless methods.

In Patent No. 007068, a computer module for selectively turning on / off electronic devices associated with each switch is required according to a series of unique tag information transmitted from a switch. There was a problem such that the on / off control module and the like is required more.

In addition, the Republic of Korea Patent No. 0444381 is an electrical wiring structure of a multi-unit house capable of remote control of the lighting fixture, and has a power line having a light switch connected to one or more lights installed in the living room or room of the multi-unit house, among the one or more A controller having a light selection button for selecting one or more to selectively connect and lighting the light, and having a remote control switch for lighting a light switch of one or more lights selected by the light selection button with remote signal control; A switch box connected to the controller to operate the remote control switch when detecting a vibration of the vibration sensor; The switch box was equipped with a base station for mounting a pager.

However, in the above-mentioned Patent No. 0444381, a wireless pager can be used to turn on and off the lighting of a room or a living room even at a remote location to further increase security and prevent intrusion of thieves. The same thing is lacking.

First, there was no lighting switch that combines ubiquitous based home automation wireless method and touch method.

Second, self-diagnosis circuit was not developed to check the operation of load on ubiquitous sensor network.

Third, it performs the basic switch function and does not add DC power supply wiring and stably supplies DC power without being affected by the operation of AC load, and loads requiring AC power while making DC power from AC power. Lighting switch device that can stably supply DC power to DC load touch sensor module, RF communication module, and power drive modules at all times regardless of the switch on / off state without affecting The need to develop it was required.

Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

Figure 2 is a block diagram showing a schematic configuration of a wireless and touch light switch device according to the present invention, Figure 3 is a block diagram for explaining the detailed configuration of FIG.

As shown in the figure, the overall configuration of the present invention consists of a light switch 1, an RF / touch receiving unit 2, a lamp 3, a home power supply (4).

Lighting switch device according to the present invention is a touch sensor module 10 for receiving a user's touch input, RF communication for receiving a remote control signal from the outside and transmitting a control signal according to the touch sensor module 10 or an external signal Module 13, a power driver module 11 for driving and supplying power in accordance with the control signal transmitted from the RF communication module 13, DC power generation module 12 for the stable supply of power, lighting lamp (3) And a home power source 4.

Here, the wall-mounted light switch performs the function of interrupting the AC power of the AC load (lighting equipment, etc.). In the case of implementing an internal integrated circuit for adding an RF-wireless touch method, the DC load is not performed without additional DC power wiring. It is generally difficult to supply stable DC power required for (MCU, RF, LED, etc.). In addition, since the DC power itself is affected by the operation of the AC load, DC loads that require a stable DC power supply operate in a malfunctioning and unstable state, and thus it is difficult to maintain the reliability of the entire operation of the switch system.

The power driver module 11 of the present invention serves as a basic switch to control the AC load. The DC power generation module 12 supplies a stable DC power that is not affected by the operation of the AC load without additional DC power supply wiring, and makes a DC power from the AC power while Always supply stable DC power to DC loads regardless of switch ON / OFF status without affecting operation.

In addition, it is to detect whether the load is operating, and through this, it has a self-diagnosis function that enables to drive and operate power stably, and A / D, D for converting analog to digital and digital signals It has a / D conversion function.

4 is a detailed block diagram of the power driver constituting the lighting switch device according to the present invention, wherein the power driver 13 also functions as an AC power controller to supply and control AC power to the AC load.

In addition, AC plays a basic role of controlling the power delivered to AC load, and generates AC voltage near zero of AC power (up to 0.5% of total power) to make stable DC power required by DC load. It is composed of a DC power generation unit 135 to generate a DC power according to the AC voltage size determined by the AC power control unit to supply a stable DC power required for the power control unit and DC load.

The AC power control unit controls the power delivered to the AC load like a general AC switch (mechanical switch). Unlike the general mechanical switch, a controller (MCU) that controls the entire switch block rather than turning the switch on and off manually by hand. Is to control the switch electronically, and when the switch is turned on to create a DC power source, only the low voltage near the zero point of the input AC power (within a maximum of 0.5% of the total power) is transferred to the load. .

When the power switch 134 is turned off, since the AC power voltage is applied to both ends of the switch, the DC power generation unit 135 can easily make the DC power using this. However, when the power switch 134 is turned on, all AC power voltages are applied to both ends of the AC load. Therefore, a certain voltage must be applied to both ends of the power switch 134 within the range that does not affect the AC load when the switch is turned on. The voltage can be used to make a DC power supply.

The key function of the AC power control unit is to generate a constant low AC voltage across the switch block so that, when the switch is turned on, it can use the low voltage near the zero point of the AC power to continuously produce the stable DC power required by the switch block. Using this, the DC power generation unit 135 plays a role of stably making the DC power required by the DC load. In order to perform the AC switch function, the AC power control unit has an AC power switch 134 which can be controlled in an electronic manner, and the triac (TRIAC) which is most commonly used for this purpose is used.

Therefore, a drive circuit is required to control the triac switch and the switch must be opened and closed at all times near the zero point of the input AC power. Therefore, there must be a circuit for detecting the zero point of the AC power. This function is performed by the AC zero detection unit 131. do. When the power switch 134 is turned on, the low AC voltage near zero required to generate the DC power is determined by the AC power controller, and according to the magnitude of the voltage, the output current of the DC power, that is, the amount of power supplied to the DC load. Since the voltage is controlled so that the voltage magnitude can be adjusted according to the output required by the DC load, this function is performed by the DC power controller 132.

The power driver 13, that is, the AC power controller is composed of an AC zero detector 131, a DC power controller 132, a power switch driver 133, and a power switch 134. Explain.

The AC zero detection unit 131 of the AC power control unit detects the zero point of the AC power voltage, which is a reference when the power switch is interrupted. When the input AC power passes zero, it generates a pulse output. Since two zeros occur every cycle, if the power frequency is 60Hz, 120 zero detection outputs are generated per second. The zero detection output is a signal that is the standard for switching on and off the power switch, and all the circuit blocks of the AC power control unit operate based on this signal.

The DC power control unit 132 of the AC power control unit adjusts the voltage applied to both ends of the switch according to the point of time when the power switch is turned on, based on the AC zero output. The block receives the output of the AC zero detection unit 131 and determines when the AC power actually turns on after passing the zero point, and applies a switch driving signal based on this to the power switch driving unit 133. Do it. Since it is not desirable to make the DC power to be used in the switch block to be unnecessarily large, it is possible to optimize the power distribution between the DC load of the switch block and the AC load that is actually controlled using the DC power amount control unit 132.

The power switch driving unit 133 of the AC power control unit serves to turn on / off the power switch under the control of the power switch driving signal output from the DC power control unit 132 and the switch block controller (MCU). When the power switch is turned on is determined by the output of the DC power control unit 132, the output of the switch block controller (MCU) defines the operation of turning on or off the power switch.

Therefore, when a signal for turning on the power switch in the switch block controller (MCU) is applied to the power switch driver 133, the power switch is turned on at the time of the switch ON that is set by the DC power controller 132 after the next AC zero signal.

The power switch block of the AC power control unit is a main switch that turns the power delivered to the AC load on and off. The basic role is the same as a general mechanical contact switch, but when the switch is turned on, a low voltage near the AC zero is applied to both ends of the switch. The difference is that it is controlled to generate stable DC power. In the present invention, a triac (TRIAC) which is generally used as a bidirectional switch is used. The rated capacity and breakdown voltage of the triac switch may be selected according to the size of the AC power supply voltage and the AC load.

When the switch is turned on, the DC power generator 135 transfers only the remaining power to the load except for a low voltage (within a maximum of 0.5% of the total power) near the zero point of the input AC power when the switch is turned on. Make DC power required for DC load. When the switch is turned off, all AC power voltages are applied across the switch, so only the low voltage near the zero point of the AC power is used to make the DC power.

5 is an internal block diagram of a DC power generation unit for the lighting switch device of the present invention. Here, the DC power generation unit 135 transfers the load to the load when the switch is ON, and uses ON / OFF of the current driver 1353 by using almost all of the remaining 0.5% of AC power. Voltage chopping control unit (Voltage Chopping) to determine the ON / OFF of the current driver (1353) in order to generate the DC power, and when the switch is OFF to generate the DC power by using only a part of the AC power required of the total AC power A control part 1351, a signal amplifying part 1352 which performs an amplifier function to accurately transmit voltage at a voltage level determined by the voltage chopping control part 1351, and a voltage chopping control part 1351. According to the signal, the current driver 1353 delivers a current to turn on the DC driver transistor without time delay.

It is a graph.

On the other hand, the self-diagnosis circuit is configured to prevent damage of the developed power driver and determine whether or not the load operates on the ubiquitous sensor network, and the detailed functions 1) reflect the characteristics of the optimally designed power driver, and 2) 3) It is preferable to include an alarm after detecting whether there is no alarm, and 3) a communication module and an interface, and the self-diagnosis circuit can be used not only for the light switch power driver but also for an outlet sensor node.

Here, the standby power of the wireless and the touch light switch can be reduced to a minimum through the wake-sleep period control during the wireless communication turn-on and turn-off of the light switch device. In other words, power is consumed at turn-on, but charging the power at turn-off greatly reduces the standby power consumption of the device.
