Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic switch for internet,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic switch device for the Internet of objects, and more particularly, to an electronic switch device that operates using a minute current flowing through a load.

In general, a wall of a building is embedded with a switch for controlling the operation of a load including illumination. However, in recent years, the use of electronic switches capable of digitally controlling the load operation has increased due to the influence of the Internet Of Things (IOT) and the home automation system. .

In the case of the electronic switch, since a driving power source is indispensably required, a separate power source line is connected to a power line to supply driving power, or a micro current flowing in the load is used as a driving power source.

However, when the power supply line of the electronic switch is connected to the power line to supply the driving power, there is a high possibility that the power supply is not likely to cause a serious problem. When a plurality of loads are connected to the electronic switch, The power line is embedded in the wall and connected to the power line. Therefore, when the building is not installed at the time of construction, the installation process is very cumbersome and consumes a large amount of money.

Therefore, in most cases where a conventional mechanical switch is to be replaced with an electronic switch, an electronic switch using a minute current flowing in the load as a driving power source is used.

On the other hand, even when a conventional communication module for transmitting and receiving a radio signal is mounted, the electronic switch using the microcurrent as a driving power source has a small amount of electric power to be charged by a small current compared to the electric power consumed in the transmission / There is a problem in that it can not normally respond to a wireless signal transmitted and received from an external terminal including a phone.

Therefore, in most cases, it is inconvenient to connect a load having a large current consumption to the main load.

An electronic switch using a conventional micro-current as a driving power has a problem in that it is impossible to control all the loads due to the influence of a short-circuit of the main load which supplies a small current in a state where a plurality of loads are connected, .

That is, the driving power of the electronic switch is not supplied due to a short circuit of the main load or a defective state, so that the operation of the electronic switch itself is stopped and the loads connected thereto can not be controlled.

For example, when a load having a high current consumption such as an incandescent lamp or a fluorescent lamp is connected to the main load, the lamp operates normally. On the other hand, when a load having a low current consumption such as an LED lamp is connected to the main load, It can malfunction.

In particular, considering that there is a tendency that the micro current flowing through the load is lowered due to commercialization of high efficiency low current electric home appliances based on the Internet of things, it is urgent to provide a method for stably supplying the driving power of the conventional electronic switch to be.

Meanwhile, the intermittent portions 110a, 110b, and 110c may be cut off so that a minute current is not supplied to the rectifying portions 120a, 120b, and 120c under the control of the controller 140 described later.

The rectifying units 120a, 120b and 120c are connected to the output terminals of the intermittent units 110a, 110b and 110c for converting AC power into DC power, The microcurrent is converted into the DC power.

Preferably, the rectifying units 120a, 120b, and 120c may be provided in a plurality of one-to-one correspondence with output ends of the intermittent units 110a, 110b, and 110c. The DC power sources converted by the plurality of rectification units 120a, 120b, and 120c are summed and charged to the power source unit 130. [

The rectifying units 120a, 120b, and 120c may be provided as bridge diodes for rectifying and outputting AC power.

The rectifying units 120a, 120b and 120c are turned on when the switches 10a, 10b and 10c are turned on and the rated current is applied through the intermittent units 110a, 110b and 110c, And outputs the converted signal to the power supply unit 130.

When the switches 10a, 10b, and 10c or the operation confirmation switches 160a, 160b, and 160c are turned on and a rated current is applied, the switches 10a, 10b, and 10c are connected between the switches 10a, 10b, and 10c and the power source unit 130, , And a separate rectifying unit 170 for converting the DC power into a DC power and outputting the DC power to the power supply unit.

[

Referring again to FIG. 1, the power supply unit 130 supplies power to the controller 140, which will be described later, and may be a condenser or a small coin battery.

The power supply unit 130 is connected to the rectifier units 120a, 120b and 120c and receives DC power. The power supply unit 130 includes switches 10a, 10b and 10c, (160a, 160b, 160c) to receive the DC power converted from the rated current.

For example, when the switches 10a, 10b, and 10c are turned off, the power source unit 130 receives the DC power converted from a small current from the rectifying units 120a, 120b, and 120c, 10a, 10b, and 10c, or the operation confirmation switches 160a, 160b, and 160c are turned on, the DC power converted from the rated current is supplied from the rectifier 170 and charged.

Accordingly, when the switches 10a, 10b, 10c or operation confirmation switches 160a, 160b, 160c to be described later are turned on, the power supply unit 130 can reach the buffered state and gradually discharge However, since the DC power converted from the small current is continuously supplied from the rectifying units 120a, 120b, and 120c, the fully discharged state is not reached.

The power supply unit 130 is charged with DC power converted from a minute current flowing through all the loads PL1, PL2 and PL3 through the rectifying units 120a, 120b and 120c. Therefore, the loads PL1, PL2 and PL3 themselves It is possible to secure a sufficient charging power even if the current consumption of the secondary battery is small, the specific load is short-circuited, or the state is poor.

The controller 140 controls the switches 10a, 10b, and 10c according to a user input or a wireless signal to turn on and off the power supply unit 130. The controller 140 may be provided to receive power from the power supply unit 130 .

However, when the switches 10a, 10b, 10c are turned on or the operation confirmation switches 160a, 160b, 160c to be described later are turned on and a rated current is applied, the wireless communication unit 150 converts DC power can be supplied to the transmission unit through the rectifying unit 170 and can be switched to the operation mode. At this time, the wireless communication unit 150 may operate in a steady state and transmit a return signal to the external terminal.

The wireless communication unit 150 maintains the above-described operation state while the switches 10a, 10b, and 10c are turned on and the load is in operation. When the switches 10a, 10b, and 10c are turned off, It may be switched to the standby mode.

Therefore, the wireless communication unit 150 can respond normally to the wireless signal transmitted / received from the external terminal, and the power consumption at normal time can be minimized.

The operation confirmation switches 160a, 160b and 160c are connected to a plurality of loads PL1, PL2 and PL3 for checking whether the device itself operates normally, PL1, PL2, PL3 to be energized.

That is, when the operation confirmation switches 160a, 160b and 160c are turned on and the loads PL1, PL2 and PL3 operate normally, the loads PL1, PL2 and PL3 are turned on, A rated current is applied to the rectification part 170 connected to the operation confirmation switches 160a, 160b and 160c and the DC power converted from the rectified part 170 to the power supply part 130 can be supplied.
