Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a switch array for a switchboard,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch array for a switchboard and an electricity saving device having the switch array, and more particularly to a switch array for a switchboard for a switchboard using a power line communication for controlling power of an electric device distributed in various rooms of a motel, To a switch array and a switchboard apparatus having the switch array.

Electric equipment installed in a rental real estate or karaoke room such as a motel is designed as a structure in which a guest (or a guest) turns the power on or off. Guests are required to turn on the air-conditioner, refrigerator, and lighting when entering and turn off the power when leaving. However, since the billing of the accommodation such as a motel does not depend on the electricity usage amount, some guests may leave the room while leaving the power source such as an air conditioner or lighting even when leaving the apartment, and energy is wasted. In order to solve some of these problems, the door key of the room is changed to the card key method, and a box for storing the card key near the entrance is provided. When the guest enters the room, the card key is inserted into the room, So that the entire power source of the room is shut off.

Accommodation such as motels has the advantage of saving energy when using the card key, but there are some inconveniences to the guests. For example, if you have a guest who wants to use a room on a midsummer, the guest will want to stay cool as soon as they enter the room, but since the air conditioner will not operate until after the card key has been inserted, .

In order to solve some of these problems, a power control system and method capable of turning on / off an electric device remotely using power line communication as proposed in Patent Document 1 has been proposed. As shown in Patent Document 1, if the individual electric devices can be turned on / off remotely, there is an advantage that the electric devices can be controlled most efficiently. However, since it is necessary to construct the control devices separately for each electric device, It is necessary to manage the electric devices at once, but the electric devices have to be managed individually. In addition, in order to install a device for controlling the on / off of individual electric devices in commercial facilities such as rental accommodation such as a motel, karaoke, video room, etc., The difficulties were also significant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a switch array for an electric distribution panel and an electric distribution panel including the same will be described in detail with reference to the accompanying drawings.

Before describing the present invention in detail, a brief description will be given of an electric facility of a lodging establishment. It is a matter of course that the present invention can easily be applied to a karaoke room, a vide room, and the like, which need to control an electric appliance installed in an independent room at the same time. In the present invention, a typical lodging company will be described as an example. The accommodation is usually made up of several layers, and each floor is equipped with a switchboard for supplying electricity to the rooms in each floor. FIG. 1 is a configuration diagram of a conventional distribution board provided in each floor of a lodging establishment, and FIG. 2 is a layout diagram in which the power supply shown in FIG. 1 is applied to each room. An inter-layer circuit breaker and room circuit breakers (C1, C2, ..., C6) are disposed in a metal box of a hexahedron whose front faces are opened and which are embedded in the wall surface of the switchboard 10. The interlayer circuit breaker is intended to block the abrupt flow of current due to an abnormal electrical connection such as a short circuit to a commercial power supply of three phases supplied from the outside. (R), (S), (T), and (N) power lines are disposed at the lower portion of the interlayer circuit breaker, and a plurality of room circuit breakers (C1, C2, ..., C6 are provided. The interlayer circuit breaker and the room circuit breaker can be used for the switching purpose to cut off the power supplied to the floor or room by forcibly stopping the power supply when the abnormal current such as short is flowed to the corresponding power line. Of course. The commercial power supply supplied from the outside is composed of R, S, T and a central ground line (N), each of which has a phase difference of 120 degrees. With respect to the vertical center axis of the switchboard, the R power and the center ground line (N) are connected to the C1 room circuit breaker to the left and to the C4 room circuit breaker to the right. The output of the C1 room circuit breaker supplies power to the electric devices disposed in the room R301 and the output of the C4 room circuit breaker supplies power to the electric devices disposed in the room R304. Similarly, with respect to the vertical center axis of the switchboard, the S power source and the center ground line (N) are connected to the C2 room circuit breaker to the left and to the C5 room circuit breaker to the right. The output of the C2 room circuit breaker supplies power to the electric devices disposed in the room R302 and the output of the C5 room circuit breaker supplies power to the electric devices disposed in the room R305. Similarly, with respect to the vertical center axis of the switchboard, the T power and the center ground line (N) are connected to the C3 room circuit breaker to the left and to the C6 room circuit breaker to the right. The output of the C3 room circuit breaker supplies power to the electric devices disposed in the room R303 and the output of the C6 room circuit breaker supplies power to the electric devices disposed in the room R306.

Although FIGS. 1 and 2 illustrate that six rooms are installed in the corresponding floor, the number of rooms arranged in each floor differs from one building to another, and thus the configuration of the power distribution board also changes. 2, power is supplied from only one circuit breaker to one room, but power is supplied from a plurality of breakers to one room in an actual electrical layout. For example, it has been described that only the power supplied from the room breaker C1 is provided in the room R301, but in practice, it is generally installed in the room R301 to receive power from the room breaker C2 in addition to the room breaker C1. However, in the present invention, it is assumed that power is supplied from only one room breaker to one room for convenience of explanation. That is, it is assumed that each room is supplied with a power source selected from among R, S, and T power sources and a central ground line (N) to supply 220V commercial power.

FIG. 3 is an overall configuration diagram of an electric appliance for a lodging establishment using power line communication according to an embodiment of the present invention. The electricity saving device is composed of a central control device and a power line communication switchboard device (hereinafter referred to as "switchboard device") connected with the power line communication.

The central control device, which is provided for each of the motels, is connected to the server device through the Internet network. The server device is a device used when a central control device provided in the motel is to be remotely identified.

As shown in FIG. 3, one central control device and a plurality of distribution panel devices are provided in one motel. The central control device is a device for generating a power control signal for turning on / off the power supplied to each room in the corresponding motel using power line communication. The switchboard apparatus is usually provided for each floor of each building and supplies / cuts off the power supplied to the connected room in accordance with the power control signal inputted through the power line communication from the central control apparatus.

The central control unit includes an Internet connection unit, an application program execution unit, a user connection unit, a display unit, a first power line communication unit, a network management unit, a first DC conversion unit, a storage unit, and a system diagnosis and treatment unit. The Internet connection unit is a unit for connecting to the Internet network, and the user connection unit is an arrangement unit for providing an interface for receiving an operation signal from a user. The application program execution unit is a unit for executing an application program according to an operation signal input from a user. For example, the application program execution unit is a unit for performing a series of procedures for a guest to input necessary information from a user when staying in and out.

The network management unit can control a plurality of receptacle devices or a plurality of remote control devices simultaneously or individually and performs a protocol for participating in the network of each receptacle device or each remote control device and manages and maintains the network status. The storage unit is a unit for storing data necessary for the control or information about the accommodation and the room, and the display unit is a unit for displaying information such as a user's input and a result of execution, and the DC converting unit converts the commercial power into DC And supplies it to each component.

The first power line communication part and the second power line communication part perform communication for transmitting data by using a power line. Usually, the first power line communication part is a master communication part and the second power line communication part is a slave communication Quot; Although not shown in the drawing, a separate system control unit is not shown in the central control unit, but each of the central control unit and the switchboard unit is provided with a system control unit. The system control unit analyzes the control signals between the units in each unit and generates necessary control signals .

The switchboard apparatus is provided with a second power line communication unit, a switch control unit, a second DC conversion unit, a switch array 51, and a system diagnosis and treatment unit. Since the second power line communication unit has been described above, a detailed description will be omitted. The switch array 51 is composed of a plurality of switch elements for shutting off or connecting the power supplied to each room. A relay switch is used as a switch element used in the present invention. In a normal state, A switch that keeps the state is used. That is, in order to supply power to each room when the power line communication does not operate normally, a relay switch that maintains the ON signal state in the normal state is used. The switch control unit included in the switchboard apparatus is a control unit for analyzing the power control signal input from the second power line communication unit and generating a switch control signal for turning on / off each switch provided in the switch array 51. The second DC converting unit converts the commercial power to DC and supplies the DC power to each of the components.

Hereinafter, the system diagnosis and treatment unit will be described. The system diagnosis and treatment unit provided in the central control unit checks whether or not the power line communication with the switchboard unit normally proceeds, and generates a control signal for resetting the central control unit when normal progress does not occur.

The system diagnosis and treatment unit provided in the switchboard apparatus checks whether the switchboard apparatus is operating normally or not. If it is determined that the switchboard apparatus is not operating normally, the system diagnosis and treatment unit controls the switch control unit to supply power to each room, As shown in FIG. In the case where the system diagnosis and treatment unit is not provided in the switchboard apparatus, there is a problem that the power can not be supplied to the respective rooms if the switchboard apparatus fails. The system diagnosis and treatment unit may be configured by adding additional hardware or modifying the switch control unit so as to additionally perform the corresponding function without adding any additional hardware. In the case of implementing without hardware, the switch control unit examines the protocol between the switchboard unit and the central control unit. If it is determined that the protocol is not normally exchanged, the switch control unit generates a control signal to continuously supply power to each room The switches are all switched on, and the switchboard apparatus is reset.

FIG. 4 is an example of implementing a part of the configuration of the system diagnosis and treatment section provided in the switchboard apparatus in a hardware manner. The system diagnosis and treatment unit may be implemented by a digital circuit as shown in FIG. 4 (a) or by an analog circuit as shown in FIG. 4 (b). As shown in FIG. 4 (a), when a digital circuit is implemented, the output voltage value of the second DC converter provided in the switchboard apparatus is converted into a digital value using an analog-to-digital converter And inputs it to the control unit. The treatment control unit checks whether the input voltage value falls within an abnormal range. If it is determined that the voltage value is in an abnormal range, the treatment control unit turns on the switch so that power is continuously supplied to each room, and then the socket unit (remote control unit) is reset. 4B, when the output of the second DC converter is input using a comparator having a reference value as one input, a voltage higher than the reference value is applied 1 " value is output in a normal case, and a " 0 " value is outputted in case of abnormality. When the value of '0' is inputted, the system diagnosis and treatment control unit generates a control signal to continuously supply power to each room, so that the switch is turned on and the switchboard unit is reset.

5 is a configuration diagram of a power line communication switchboard apparatus according to an embodiment of the present invention. In the switchboard apparatus shown in FIG. 5, the system diagnosis and treatment section is omitted. In the switchboard apparatus 100 according to the present invention, an interlayer circuit breaker and room circuit breakers C1, C2, ..., C6 are disposed in a hexahedron-shaped power distribution board housing that is installed on a wall surface and opened, A second DC converting unit and switch arrays 51 and 57 are provided. In the present invention, the first switch array 51 provided in the space between the left side of the cabinet housing and the first switch array 51 installed in the left side of the cabinet and the room circuit breakers C4 and C5 And C6 and a second switch array 57 provided in a rectangular shape in a space between the right sides of the cabinet housing.

The switch arrays 51 and 57 are provided with a plurality of switch elements r1, r2, ..., r6. Each of the switch elements r1, r2, ..., and r6 is connected to two of the two power supply lines supplied from the room circuit breakers C1, C2, ..., It has a switching function to connect or disconnect a single power line. When the switch control signal is input from the second power line communication unit, the switch control unit transmits an on / off control signal to each switch device to cut off or connect the power supplied to each room.

6A and 6B are photographs of a prototype switch fabricated according to the present invention and some equivalent circuit diagrams thereof. 6A and 6B, the switch array is provided with a printed circuit board 65 on a rectangular switch array housing having a narrow width as a whole, and on the printed circuit board 65, one switch element 52 And two connection ports 54 and 56 electrically connected to the respective switch elements 52 are arranged in the vertical direction. In FIG. 6A, ten switch element groups are formed in one switch array. Needless to say, the number of switch element groups that can be installed in the switch array can be arbitrarily changed. The printed circuit board 65 is provided with a power supply wiring 63 for supplying power supplied from the second DC conversion unit and a switch control wiring 61 for transmitting a switch control signal applied from the switch control unit. The first connection port 54 of the two connection ports 54 and 56 is electrically connected to the input terminal of the switch device and is screwed into a single power line input from the room breaker and the second connection port 56 is connected to the output terminal of the switch device And connected to the power line of the room. Needless to say, it is needless to say that the method of fastening the power supply line to the connectors 54 and 56 may be variously structured such that the power supply line can be inserted in addition to the screw fastening method.

The use of the electricity saving device shown in FIG. 3 and the switch array shown in FIG. 6A has an advantage in that power supplied to each room can be easily blocked. However, in the case of a remote control type electric apparatus which is operated by applying a separate operation signal in addition to the power supply, it can not be operated only by simple power supply. For example, in case of air conditioner, it is good for the guest to operate from the moment the guest is assigned to the first floor counter. In order to operate the air conditioner, besides the power supply, the operation signal can be operated by remote control. In order to solve such a problem, a method has been proposed in which a remote control signal is transmitted from a central control unit, a separate receiving unit is installed in a room, and a remote control signal is emitted after a receiving unit receives a remote control signal. However, this method can be the ideal control device in theory, but it is difficult to apply it because a lot of additional equipment must be installed in order to be practically applied.

To solve this problem, the present invention proposes a power source recognition remote controller as shown in FIG. The power source recognizing remote controller shown in FIG. 7 is a device for generating a control signal for turning on the operation of the electric device for a predetermined time when power is applied. The power supply recognizing remote controller includes a third DC converter for converting AC commercial power to DC power, a voltage regulator for adjusting the output voltage of the third DC converter to a predetermined voltage, an infrared transmitter for outputting infrared rays to the electric equipment, .

The power source recognizing remote controller according to the present invention generates a control signal for continuously transmitting an operation signal for turning on the remote control electric device for a predetermined time (for example, 10 seconds) through the infrared transmitter. With this configuration, when the power is cut off and applied to each room, the power source recognizing remote controller converts the commercial power into DC power using the third DC converter, converts it into a DC power with a proper operating voltage, . Therefore, the voltage regulator may be omitted if the voltage supplied from the third DC converter matches the operating voltage of the remote controller or the like. The remote control unit turns on / off the infrared ray emitting unit using the infrared ray control signal stored in the storage unit 73 for a predetermined time when the power is applied. The remote control unit used in the present invention uses an MCU (MSP 430) of Texas Instrument, and the infrared light emitting unit is directly connected to the GPIO (general purpose input output) port of the MCU. The configuration of the remote control unit and the infrared ray emitting unit can be changed into various forms by a person having a little electric skill. That is, it is of course possible to provide a separate shutoff switch at the front end of the infrared ray emitting unit, and the remote control unit may turn on / off the shutoff switch.

Therefore, according to the present invention, it is possible to operate the remote control type electrical apparatus only when power is supplied to the room. In order to achieve such a function smoothly, the power source recognizing remote control unit must be provided with a storage unit 73 for storing data for turning on / off the infrared ray emitting unit for a predetermined time to operate the infrared ray transmitting unit. Therefore, it is necessary to store a separate memory (storage unit) in the remote control unit or a memory (internal storage unit) 73 provided in the remote control unit. For example, in the case of a domestic air conditioner, brands such as Samsung, LG, and Sentry are used, and infrared signals that operate the infrared signals are different from each other. The inventor of the present invention designed infrared light emission data of all brands to be stored in a storage unit and sequentially repeatedly emit light through the infrared light transmitter for a predetermined time so that all brands of air conditioners can be operated as one remote control device. When operating in this manner, it is possible to solve the problem of designing a separate remote controller according to the brand.

Further, the storage unit provided in the remote control unit may further include infrared light emission data for turning on all electric devices installed in the corresponding room. For example, if a room is equipped with a Samsung air conditioner and if an LG TV is installed, a remote control unit stores infrared light data for turning on the Samsung air conditioner and the LG TV. When the power is supplied, .

In addition, the power source recognition remote controller according to the present invention has a timer function for sending an operation signal for turning on the electric device for a certain period of time to the infrared transmitter after the power is turned on. The reason is that after the guest arrives in the room, it is necessary to operate the air conditioner with the remote control (for example, when turned off), and if there is no timer function, , Which causes the problem of turning on the air conditioner even when the guest turns on the air conditioner.

While specific embodiments of the invention have been illustrated and described, it will be obvious that the same may be varied in many ways by those skilled in the art without departing from the spirit of the invention. Such modified embodiments are not to be understood individually from the spirit and scope of the present invention, but are to be regarded as falling within the scope of the appended claims.
