Description

Lighting and Outlet Switching Control System for DC Control Power Line Communication

The present invention relates to a lighting and outlet control system using DC-controlled power line communication, and more particularly, to implement power line communication in a separate building. The present invention relates to a wiring technique for preventing an operation delay state.

In general, in the case of large and large electric facilities, that is, facilities with private power receiving facilities (contracted power of 100KW or more), noise from the outside is small, so even if a minimum filtering circuit is applied, operational errors in power line communication can be avoided. little. However, in the case of a shopping mall or a building other than the above facilities, noise generation varies considerably according to time zones and regions due to the common use of the neutral wire of a pole transformer made of △ -Y of the KEPCO power distribution line within 3kW ~ 95kW of the low voltage power supply.

Harmonics and impulse noise generated during the lighting of typical electronic circuit devices (e.g., electronic fluorescent ballasts and AC-DC charging device adapters) prevent the stable transmission and reception of power line communication.

As a means of eliminating this problem, an active active filter, a harmonic filter, or a passive filter (ACL, DCL) for the line is installed in the power line communication transmitter and receiver to respond to the electric environment. However, there is a limit to removing noise with a filter, and it is limited by filter equipment price and product size.

As another method of removing the noise, the response speed and frequency band of the transmission / reception signal may be adjusted to be adjusted, but the above method may be caused by interference with power line communication means (mainly KEPCO distribution line) outside the customer (user). It is restricted by legal and property rights issues.

Another method is to detect the zero cross (ZCP) of the power supply line voltage and to detect the address (RF) by the comparator. However, it should always be in two-way transmission and reception state, and it is not easy to avoid the interference of operation between one set unit (controller and its dependent response switch) and another set unit. There is a disadvantage to be installed. Therefore, the above method is also difficult to completely block noise in power line communication.

As another method, the present applicant is proposed in the 'applied power control device of a power outlet communication and an electrical device' (KR 10-2009-0125193), but in the above case, standby power consumption consumed by the switch itself. This switch consumes about 0.75W, resulting in a reverse energy savings objective.

1 is a view showing the indoor wiring of a typical building according to the prior art. Referring to FIG. 1, an outlet 110 and an electrical device 120 are connected to a power line 100 connected to a distribution panel 200, and the power line 100 is connected to an indoor wiring method (serial, parallel, complex) and the like. The number of wire strands is added as many as the number of switch circuits, and in the case of the outlet 110, there is no means for individually turning on and off, and only the distribution panel can be turned on and off.

In addition, lighting does not have the function of pattern (group setting, memory) control or collective lighting, and it is not possible to cut off standby power of the outlet, which makes energy saving not easy, and material and construction cost due to reconstruction when remodeling a building. Has the disadvantage of increasing. As a method for solving the above problem, after coping with the existing wall tumbler switch RS485 remote controller controller 300 by using the RS485 communication as shown in Figure 2 to wire the RS485 communication line 320 with the operation switch 310 There is a method of pattern control, but the control line 320 has to be constructed separately, there is a disadvantage that the additional equipment price is expensive.

In case of an outlet, use a blocking outlet equipped with a manual switch, an infrared remote control circuit using an internal electronic circuit of the outlet (KR 10-0954236), or a method of attaching an outlet product having a function to cut off standby power ( KR 10-0932637). In the case of the outlet, the price is high, and the operation method and the wiring system are the same as the conventional construction method.

In order to simplify the electrical wiring in the facility, and to control the outlet and the electrical equipment while reducing the standby power consumption, the present applicant has previously filed a 'power control device for an electrical apparatus and an electrical apparatus using power line communication' (KR 10-2009). -0125193). Referring to FIG. 3, the above technique is a breakthrough method that can be attached to a new building as well as an existing building without a separate electric work, but is a noise introduced through a power line 100 connected to a general distribution line. This may cause a malfunction. As a countermeasure against noise, a separate individual filtering circuit is required and there is a slight anxiety factor depending on the electrical usage environment.

Therefore, the present invention is made of a structure that can compensate for the above disadvantages with a simple configuration in a new building can supply the product at a low price, only one strand of power line and one strand of DC power line for control power supply in one pipe It is a system that can completely block noise as well as economic effect to save material and labor cost by wiring.

Second, power line communication is possible with only two lines of power line and one line of control DC power line in a single pipe, which greatly shortens the working time and reduces labor costs as well as wiring and piping materials.

Thirdly, it is a wiring system that can always change the switch, light and outlet system without any additional electric work when remodeling or changing the building structure.

Fourth, the energy saving effect is very excellent due to the group control of batch switches and lights and the standby power cut-off function of the outlet (saving more than 15% compared to the existing standby power system).
