Description

TECHNICAL FIELD [0001] The present invention relates to a power saving control switch device via a PLC and a switching method thereof. [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power saving type switch device through a PLC (Power Line Communication) and a switching method thereof, more specifically, The present invention relates to a power saving type switch apparatus and a switching method thereof that detect the presence or absence of a human body both inside and outside a place where the lighting facility is required and control the lighting apparatus more precisely by mutual communication through a PLC.

In recent years, damage to human life and property has increased dramatically due to weather events or natural disasters. In particular, the crisis of energy depletion is getting worse because of indiscreet use and abuse of human energy.

In other words, it is a time when the efficient use of energy becomes more important because of the natural disasters, damage to electric power facilities and pollution to the natural environment. Saving energy is required in various fields, but energy saving in a typical home or office environment is a very important task. Of these, the proportion of energy used for lighting is increasing every year due to the higher quality of living environment. For this purpose, an automatic switch on / off system through human detection is actively utilized in the home as well as the office environment.

However, in the practical use of the automatic power saving type switch by human body detection, in order to compensate for the human body detection error, after the human body is detected, the switch is turned on to turn on the lamp, Which often causes inconvenience to the user. This is because, if the user's motion is not captured, or if the human body sensor is not detected by the human body sensor, the human body is automatically turned off even if it is indoors. In order to avoid this, there is a case where the user forcibly turns off the phenomenon that the light is automatically turned off by deactivating the human body detection sensor. Such bypass use of the conventional power saving type switch makes the automatic power saving type switch unnecessary by human body detection And its effectiveness is deteriorating.

The characteristic of the human body detection sensor is that it detects the far-infrared rays (infrared rays emitted from the body temperature) coming from a human or an animal. In this case, it does not detect the infrared ray itself, but detects only the change of the infrared ray. Therefore, when the person does not move, a problem that the human body can not be detected occurs. In addition, there is a case where a thick coat is worn and a human body can not be detected, and when hot air passes, a human body may be detected as a human body even if there is no human being.

Therefore, if a device such as an incandescent lamp is continuously shaken in front of the sensor, it is difficult to give credibility to the operation such as recognition and detection as a human body. In some cases, it is necessary to pay special attention to the fact that if the final exit attendant forces the sensor to operate and then does not manage it, it may cause the lamp or the air conditioner to operate overnight, unlike expected.

In order to control such a phenomenon, it is possible to freely set the automatic and manual modes. However, such a device may cause confusion in use to the user and inconvenience of adding a device unnecessarily to cause malfunction.

In order to solve such a problem, Korean Unexamined Patent Publication No. 2012-0096815 (published on Aug. 31, 2012) discloses a passing direction discrimination and counting apparatus and method using a detection parallax. The present invention relates to a sensing method and apparatus for determining the moving direction of an object or a person such as a person or a car, and for counting the moving direction. Especially, it does not cause inconveniences of users or workers in each space in the building, but it also identifies the number of people in the space and suggests technologies that can be utilized for space energy management, disaster prevention management and security management.

That is, in the prior art document, there is still a problem in using an automatic power saving type switch without forcibly disabling the operation of the automatic power saving type switch, because it operates in an undesired direction of the human body detection and an inaccurate human body detection for a conventional human body detection sensor. Therefore, the present invention proposes a method for improving the accuracy of human body detection for each room in the room through a conventional human body detection sensor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a power saving type switch device and a method of configuring the same according to the present invention will be described with reference to the accompanying drawings.

1 is an exemplary view for installing and operating a power saving type switch device through a PLC according to an embodiment of the present invention.

As shown in FIG. 1, in order to install the power saving type switch device through the PLC, a switch 200 having a PLC interface to which a PLC communication function is added to a conventional lighting switch is installed for each room, and in some cases, An outlet 400 is provided to connect each switch and a receptacle to a remote light controller (control server) 100 including a PLC access point (AP) through a power line. At least one sensor unit installed in each room senses whether a human body is present in the corresponding room, and the sensed human body sensing signal is transmitted to a remote light controller through a PLC interface via a power line, Determines whether to turn on or off the lamp in the corresponding lamp, and transmits the command to the switch having the PLC interface provided in each room through the PLC, and the switch accordingly controls the lamp (also referred to as a lighting apparatus or a lighting apparatus) .

In the present invention, various kinds of sensors for detecting the presence of a human body including an infrared sensor, a temperature sensor, a motion detection sensor, an image sensor, a thermal sensor, a thermal image sensor, . In other words, it is also possible to include a laser sensor for counting the number of visits and visits. In addition, it is possible to control the illumination device not to be turned on even if a human body is detected when the ambient brightness is further increased, by further including an illuminance sensor. It is desirable to install the sensor in the vicinity of a ceiling or a window that can best reflect the illuminance of the room in the case of the ambient light sensor. In case of the human body sensor, it can be installed and maintained easily And the price can be lowered. However, such a place of installation is not particularly limited due to the present invention. However, it is preferable that the installation position of the human body detection sensor is installed at the center of the room or at a position for minimizing the dead zone for human body detection. Such sensors, by themselves, can be very difficult to detect if a person is present in the room if they are sleeping or are not moving for a long time. Therefore, in this case, it is possible to detect the human body smoothly even if it is difficult to perform the human body detection because there is no movement for a long time in one room, .

The human body detection result detected by each sensor must be transmitted to the remote light controller through the network through the PLC. To this end, the determination result of the human body detected in the sensor unit is transmitted to the power saving switch by the near- can do. This transmission method can also be transmitted to each power saving switch via NFC including IR, RFID, Zigbee, LED communication or a combination thereof.

As described above, each of the power saving switches transmits the human body detection result sensed by the sensor unit to the remote light controller through the PLC communication means possessed by itself. It is possible to transmit the human body detection result from the sensor to the remote light controller through the PLC interface installed in each power saving switch 200 or the outlet 400. [ To transmit information over the power line, it is desirable to connect to live AC power line (not to load or light) connected to the switch.

When a person moves to another room through one visit (see a dotted line arrow in Fig. 1), it is possible to detect the presence of the human body more reliably and more precisely by sensing the movement of a person. Also, if a person is staying in a blind spot (person in the kitchen corner of FIG. 1) and the person is not detected moving through a particular door, the person can still use the sensed result It is possible to generate the detection result. In addition, if a person enters the room and does not move for a long time (a person sleeping in the bed of FIG. 1), the presence of a person can be effectively determined through bidirectional human body detection, and the power saving switch can be controlled through this.

It is preferable to place one remote light controller 100 having PLC access points in each home or office, but it is also possible to install a separate remote light controller when the household is finally disconnected. Therefore, There is no limit to the number of.

We will discuss the concept of connecting the power saving switch through the PLC interface according to the type of the lighting apparatus installed in the office and the home.

2 is a conceptual diagram of a connection including a grouping of power saving type switch devices through a PLC according to an embodiment of the present invention.

As shown in FIG. 2, at least one PLC interface (I / F) switch 200 installed in each room through a power line and a sensor unit 300 are connected to a remote light controller 100, It is possible to check whether there is a person in each room by grouping and managing adjacent rooms between the same visits in consideration of the adjacent positions of the entire room. As shown in the figure, the room 1 and the room 2 are grouped together and the room 2 and the room 3 are grouped together so that the room 2 may be overlapped with another group. The configuration of such a group is a means for enabling the human body to be detected more finely.

The remote light controller 100 associates the human detection signals transmitted from the respective rooms with respect to the adjacent room to detect the presence or absence of the human body in and out of the rooms bound to the bundle so as to simultaneously detect the presence or absence of the human body, The human body can be detected even for a human body located in a dead zone. In other words, if a human body is not detected in one room between adjacent rooms and a human body is detected in another room, it is possible to judge that a person's movement has occurred. Otherwise, the person is not moving in a specific room, When a person is located, there are many cases where the human body can not be detected.

The light control signal is generated remotely based on the signal transmitted from the sensor unit and the PLC interface switch in the individual room. The generated light control signal is transmitted to the power saving switch of each room through the PLC interface again so that the desired power saving switch can be controlled. The control result is transmitted to the smart terminal such as a smart phone through the Internet again. In order to be able to view and control these results on a smart phone, an application including a user interface defining a desired function should be installed in a smart terminal. With a smartphone, lighting can be more conveniently controlled.

That is, since the remote light controller 100 knows the unlit status of the entire household, the smart phone 600 can be notified of the status information through the wired / wireless network 500. [ The notified information can be displayed by an application installed in the smart phone, and the user interface of the smart phone receives the configuration information of the corresponding user interface from the remote light controller, and is displayed on the smart phone. Since the smartphone enables the outside of the home to accurately grasp the lights out of the house using the smartphone app even when the landlord goes out, it is possible to confirm the lighting state of the house anytime and anywhere, Can be controlled.

Hereinafter, functional blocks for the internal structure of the remote light controller will be described.

3 is a block diagram illustrating a configuration of a remote light controller for controlling a power saving type switch device through a PLC according to an embodiment of the present invention.

The remote light controller 100 may be configured to include an access point for PLC communication, an NFC, a wireless LAN, a wired / wireless communication network, or a combination thereof. In addition, the remote light controller 100 may include a user interface unit 110, a user command analyzer 120, a storage interface unit 130 and a switch status collecting and commanding unit 140.

Here, the remote light controller 150 determines whether there is a person in a specific room based on the human body detection of the entire home and each human body detection signal in a situation where each room is grouped according to the present invention, and accordingly, And transmits the command to each power saving switch through the PLC. It also supports interpretation of user commands and light on / off commands, as well as control of the user interface and storage interface. In addition, the user can download the app to the user, and access the information desired by the user through the lamp status information storage unit.

The user interface unit 110 notifies a light state of a corresponding home on a smart phone through an application and transmits a configuration file for the user interface desired by the user every time in order to receive a control command from the user, . That is, a template for a certain user interface is stored, and when a template desired by the user is selected, the user creates a desired GUI. At this time, the application of the user terminal can display the desired user interface without compilation by using the user interface configuration information. Of course, this user interface configuration function is not necessarily included.

The user command interpreting unit 120 interprets the user command inputted from the user as a function block for interpreting the user command as a command for controlling the lamp, interprets the command transmitted from the user terminal according to the user interface command specified in advance, To the remote light control unit so as to generate an instruction so that each light can be controlled.

In addition, the storage interface unit 130 continuously stores the lights on and off for each household, stores them in the form of a table and manages them, so that at a certain point in time the person is detected in the room and at another point, So that the information can be grasped. This information accesses and informs the information stored in the lamp state storage whenever the user desires. The light condition storage unit may store information related to a user interface for remote light control as well.

The switch status collecting and command unit 140 collects the switch status including the sensing information transmitted from the power-saving type switch input through the PLC interface and delivers the switch status in a form suitable for use in the remote light control unit, And performs a function of generating a command to be transmitted to the power saving type switch for the operation of the power saving type switch.

Accordingly, it can be seen that the remote light controller is composed of various user interfaces including a remote light controller, a communication interface, and a command interpreter.

Hereinafter, a power saving switch 200 having a PLC interface for receiving a command of a remote light controller according to the present invention through a PLC interface and controlling each lighting lamp will be described.

4 is a block diagram illustrating a configuration of a power saving type switch device through a PLC according to an embodiment of the present invention.

4, if two rooms A and B are adjacent to each other with a doorway interposed therebetween, a power-saving switch 200 having a PLC function is mounted in each room, The human body detection signal inputted through the controller 300 is transmitted to the remote light controller 100 through the PLC. The power saving switch 200 through the PLC according to the present invention includes a processor 230, an internal DC power generator 220, and a power line communication (PLC) interface 210. Here, the power line communication interface unit 210 includes a PLC modem 211, an AFE (Analog Front End) 212, and a line driver 213.

The power line communication interface unit 210 may be configured using a conventional commercial PLC modem or may be configured to arbitrarily configure a power line communication interface in accordance with the user's convenience. It is desirable to use it adaptively as needed.

And an internal DC power generator 220 for receiving DC power from the power line communication interface unit 210 or directly from the power line to generate DC power. This is because there is a portion requiring a DC power source, such as the processor 230. The processor 230 converts the sensing result input from the sensor unit 300 from analog to digital (not shown) And the shutdown signal of the power saving switch is generated based on this.

The processor 230 processes a signal input from the sensor unit 300 and communicates with the remote lighting controller 100 through the power line communication interface unit 210. That is, in addition to transmitting the sensing signal of the sensor unit 300 to the power line communication interface unit 210, the processor 230 receives the signal input from the power line communication interface unit 210 to generate a switch-off signal, And the like.

The internal DC power generation unit 220 may be required in the power line communication interface unit 210 and the processor 230 that require DC power. That is, since the power saving type switch 200 through the PLC for controlling the power saving switch shut-off signal often does not have a separate DC power source, it is necessary to prepare the DC power source, And may further include a power generating unit 220.

5 is a state transition diagram for controlling operation of a power saving type switch device through a PLC according to an embodiment of the present invention.

As shown in FIG. 4, when two rooms face each other adjacent to each other, a two-bit state diagram can be shown for bidirectional human body detection. In addition, when three rooms are associated with each other, The operation of the power-saving type switch can be controlled through the state diagram of FIG.

In this case, when both of the two rooms are turned off (00), when A is turned off and B is turned on (01), A keeps turning off and B turns on. When A is OFF and B is ON state (01), A is ON and B is OFF, A is transited to ON state and B is transited to OFF state.

5, in order to check whether or not a transition occurs from the previous state to the current state, the following relationship holds.

That is, the relationship z (t) < = A (t) is established.

In addition, with respect to the state transition in which magnetic feedback occurs, the previous state can be maintained as it is, and the state is not changed. Therefore, z (t) <= A (t-1) and A (t), and A (t-1) = A (t).

The implementation of the state transition diagram realizes the logic as shown, so that it is possible to directly utilize it to sense the motion of the human body and control the switch. Whether or not the whole bi-directional human body detection and the operation of the power saving switch can be performed through the human detection of these two adjacent rooms will be described hereinafter.

5 is a flowchart illustrating an operation of a power saving type switch device through a PLC according to an embodiment of the present invention.

In the situation where the adjacent rooms are grouped together, the two-way human body detection is performed according to the state transition diagram shown in FIG. 5 by using the sensing result of the human body detection sensor in each room. Based on the result, . It also determines whether a person is re-occupied in a particular room.

Particularly, in the present invention, the power saving type switch to which the PLC is applied has a passive mode and an automatic mode. When the passive mode is operated in the passive mode, the person turns off the lamp in the corresponding room. When a new person enters the room with the lamp turned off, it switches back to automatic mode to automatically turn on the lamp. In this case, it is not detected when it is rewired. Also, in the automatic mode, the person keeps the lamp on in the room until it is determined that the person has entered the room and then left the room again.

In a home or office environment composed of a plurality of rooms or a living room, adjacent lighting locations are grouped together and checked whether a person is present or not through the bi-directional human body detection in each grouped room (S110). The presence or absence of the entrance is detected by a human body detection sensor installed in each room, received from a power saving switch having a PLC of each room, transmitted to a remote light controller through a power line, and the presence or absence is determined according to the method described above (S120). If it is determined that the remote light controller is to be entered, a command to turn on the lamp is transmitted to the power saving switch via the PLC, and the power saving switch turns on the lamp (S140). If it is determined that the remote controller is not in the remote controller, the lamp is kept off (S130). When the light is on, it is checked whether or not the person is leaving through the two-way human body detection between neighboring illumination places (S150). The result of the sensing from the human body sensor installed in each room is received from the power saving switch having the PLC of each room, and is periodically transmitted to the remote light controller through the power line. The remote light controller receives the information, (S160). If it is determined that the remote light controller is to be removed, a command to turn off the lamp is transmitted to the power saving switch via the PLC, and the power saving switch turns off the lamp (S130). If it is determined that it is not the case that the remote light controller is removed, the lamp is kept on.

As described above, the present invention relates to a power saving switch device through a PLC and a method of configuring the switch device, and more particularly, It is possible to more precisely control the lighting apparatus by detecting the presence or absence of a human body both inside and outside the place where the facility is required and by mutually communicating through the PLC. In addition, it is possible to detect the entire human bodies of the illumination places and mutually share them through the PLC to detect where each human body exists in the individual illumination place, thereby reducing errors due to local human body detection, By communicating with the control center through the app, it is possible to control the switch device more conveniently. Accordingly, it is understood that the present invention has an advantage of suppressing unnecessary power consumption and increasing power efficiency.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. .
