<Configuration of the room detection device>

The room detecting apparatus according to the present invention cuts unnecessary power of devices that consume power such as electronic devices, fans, lights, and air conditioners provided in a partitioned space of an office building, a school (including primary, secondary, high school, and university). The invention is intended to improve energy efficiency. Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and function (method) of the room detection apparatus according to the present invention. However, one embodiment to be described below is described by taking a lecture room, a faculty room, a computer room, etc., which are partitioned spaces of a university building as an example, but is not limited thereto. All may be applied when provided.

First, the room described in the present invention refers to a case where a person enters into a partitioned space of a building and is currently staying in a partitioned space. In other words, if at least one of the students in the classroom stays in the classroom, it is called a classroom. In addition, sampling refers to a case in which still images of different time zones are extracted from moving images photographed at different time zones. On the other hand, electronic devices, fans, lighting equipment, air conditioners and the like provided in the partitioned space described above will be collectively referred to as power consumption devices.

As shown in FIG. 1, an apparatus for detecting occupancy according to the present invention includes a power consumption device 10 installed in each partitioned space 110 and wired or wireless communication with the power consumption device 10. Control computer (210,220,230) for monitoring and controlling the power consumption by the device, and the integrated energy management computer 300 for monitoring and managing the power consumption used in each compartment by wire or wireless communication with the control computer . Hereinafter, each configuration will be described in detail.

As shown in FIG. 1, a partitioned space of a university according to the present invention may be classified into, for example, an administration room 110, a computer room 120, a lecture room 130, and the like. In each space, a control signal for operating the power consumption device 10, the sensor module 30 for acquiring the environment information, and the power consumption device according to a generated command to turn on / off the power consumption device The controller 20 which outputs is provided.

The control computer 210 may be provided corresponding to the number of each partitioned space. As an example, control computers 211, 212, 213 are provided in the administrative offices 111, 112, and 113, respectively. In FIG. 1, the administrative room 110, the computer room 120, the lecture room 130, and the like are divided into respective partitioned spaces, but the area of one partitioned space is at a distance that wireless communication cannot reach. It may be divided into a plurality of partitioned spaces. That is, when the area of the executive chamber 111 is too large, the executive chamber 111 may be divided into a plurality of partitioned spaces. Therefore, the control computer 210 may be additionally installed to correspond thereto.

Each of the controller 20 and the control computers 210, 220, 230 provided in the administration room 110, the computer room 120, the lecture room 130, and the like are connected to each other by wire or wireless S1. In the case of a wired connection, it may be connected by serial communication (RS232c or RS485) or LAN (LAN). In the case of a wireless connection, it may be connected by a Zigbee communication protocol. The controller 20 exchanges data with the control computers 210, 220, 230 by a wired or wireless connection.

The control computer 210 provided in each partitioned space is connected to the integrated energy management computer 300, preferably LAN (S2, LAN) to exchange data with each other.

The power consumption device 10 provided in each partitioned space may be a computer, a projector, a fan, a lighting device, an air conditioner (for example, an air conditioner), and the like, as described above, and various power consumption according to the characteristics of each partitioned space. Additional equipment may be provided.

As shown in FIG. 2, the sensor module 30 provided in each partitioned space includes a voice recognition sensor module, an infrared (IR) sensor module, a heat ray sensor module, and a camera module. It generates a human body detection signal to check whether there is. In addition, by providing the illuminance sensor module and the temperature sensor module, if necessary, even if a person exists in the partitioned space, it is possible to turn on / off the power consumption device according to the brightness and temperature of the surrounding environment.

As shown in FIG. 2, the voice recognition sensor module 31 is installed in a partitioned space and detects a human voice to generate a human body detection signal. In this case, the human voice recognition is not a room, for example, when passing a corridor, so a human body detection signal should not be generated. It may be desirable to. In addition, it may be possible to detect whether the room is limited by limiting the frequency or amplitude of the voice recognition signal. In the case of human voice, the frequency generated is about 200 to 3.5 kHz. Therefore, only those frequencies can be filtered to generate the human body detection signal, or the amplitude of the filtered frequency can be measured to generate the human body detection signal only by a certain level or more amplitude. will be. Such a restriction may be made in the voice recognition module or may be implemented by the controller 20 described later.

The infrared sensor module 32 installed in each partitioned space detects the wavelength of the infrared region emitted by the human body and generates a human body detection signal. In the case where each partitioned space is a classroom, for example, the infrared sensor module may be installed directly on both doors of the classroom, or may be installed in plurality at each point of the ceiling as necessary. As an example, when the infrared sensor module is installed on the door in the direction of entrance and exit of the classroom door (and thus on the door of the hallway), and installed on the door of the exit direction (and therefore on the door in the classroom), the infrared sensor module is installed in the direction of entrance and exit. The human body detection signal generated by the infrared sensor module is a signal capable of counting the number of people currently occupied. In addition, the human body detection signal generated by the infrared sensor module installed in the direction of leaving is a signal that can count the number of people who are currently leaving. Using this signal, the controller 20 can calculate the number of people currently occupied.

Since the voice recognition sensor module and the infrared sensor module described above are inexpensive, they are suitable for a basic system requiring general resilience detection or inexpensive system specifications. Since the following human body sensor module is more expensive than the voice recognition sensor module and the infrared sensor module, it may be desirable to apply it to a system requiring security or accurate room detection.

The hot wire sensor module 33 installed in each partitioned space senses heat emitted by the human body. The distance for detecting the heat emitted by the human body varies according to each product, and therefore, it is desirable to install a sensor of a type suitable for the installation site. The hot wire sensor module is preferably installed at the center point of the ceiling of each partitioned space to allow a wide range of human body detection.

The hot wire sensor module causes a malfunction when the student's movement in the classroom is static or the human body moves away from the installed position. Therefore, in the present invention, by installing a camera module to be described later to detect the human body to determine the two signals at the same time to prevent such a malfunction.

The camera module 34 installed in each partitioned space captures a video of a human body entering and leaving. The performance of the installed camera determines the number of pixels and the number of frames taken per second. In the present invention, since a person entering or leaving the classroom is detected by acquiring a still image using the captured video, a high specification camera module may not be required.

There are various types of camera module 34 such as a USB camera, a camera supported by a network, and also there is a pixel difference of a video photographed according to the camera type. Therefore, it is necessary to select the type of camera by referring to various specifications such as the feature of the place to be installed and whether it is used for accurate human detection and security. According to the communication method of the camera module 34, the controller 20 or the control computers 210, 220, and 230 connected thereto may have the same communication module.

The signal generated from the temperature sensor module 35 and the illuminance sensor module 36 installed in each partitioned space may be used for power-consuming devices according to the environment around the classroom even when the human body detection signal is obtained from the above-described sensor module. It can be an auxiliary decision factor in operation. That is, the temperature sensor module measures the temperature in the classroom, and the illuminance sensor module measures the illuminance in the classroom. Therefore, even when there is a person in the classroom, the heater or the air conditioner can be stopped when the temperature is at an appropriate temperature, and the lighting device can be turned off when the illumination of the lecture room is sufficient (for example, in the middle of the day).

Each of the above-described sensor modules can be packaged and installed in a ceiling by modularizing them into one, but may be separately installed in a partitioned space according to the characteristics of each sensor module (for example, an optimal place for sensing a human body). In addition, when the position of the person who is occupied according to each sensor attachment position can be known, it may be possible to control the power consumption devices such as lighting equipment, air conditioners, computers, etc. according to the position of the person. As an example, in the case where each compartment is the computer room 120, one or more people who use the computer room are crowded around and the location of the computer can be known. By turning off the power can be used efficiently.

The controller 20 according to the present invention may be provided in a space to easily transmit a control signal to the power consumption device 10 by wire or wirelessly, and may be provided in a ceiling of a partitioned space. The controller 20 receives the human body detection signal generated from each of the sensor modules 30 described above through the communication unit 21 by a protocol suitable for each communication method. The input human body detection signal is transmitted to the occupancy determining unit 22, and the occupancy determining unit determines whether a person exists in the lecture room by using each sensor signal. At this time, as described above, in the low-cost basic system, which is an embodiment, it is determined whether or not to receive a signal by the voice recognition sensor module 31 and the infrared sensor module 32 only. In another embodiment, in an advanced system requiring security or the like, a hot wire sensor module 33 and a camera module 34 may be added. Therefore, in the high-end system, in addition to the two sensor modules used in the low-cost basic system, the heating sensor module 33 or the camera module 34 may be added, or both the heating sensor module 33 and the camera module 34 may be added.

The occupancy determining unit 22 may receive the information on the temperature and illuminance in the lecture room from the sensor modules 35 and 36 in addition to the human body detection signal, and may not turn on the lighting device or the air conditioner even when the person is in the classroom. When the occupancy determination unit 22 determines whether a person exists in the lecture room by the human body detection signal, the power consumption device control unit 23 instructs the power consumption device control unit 23 to be turned on or off based on the determination data. Each signal is generated. For example, in order to turn on or turn off the lighting device, a control command generated by the power consumption device control unit 23 is transmitted through the communication unit 21, and the lighting device includes a communication unit having the same protocol as the communication unit 21 of the controller. Control command can be performed. However, the control of the lighting device may be performed by the lighting device itself, or may be implemented by a switching device (which may be attached to the classroom wall or may use a switchable power strip) to switch the power of the lighting device. It will be apparent that such embodiments do not limit the various embodiments of the present invention. Therefore, control switching of air conditioners, fans, computers, projectors, and the like other than lighting equipment will be the same. However, power on / off of the computer and the projector will be described later in more detail.

The communication unit 21 of the controller communicates with the sensor module 20 and the power consumption device 10 or with the control computer 210. In order to receive a signal input from the sensor module 20, the communication unit 21 may be configured to a standard suitable for each sensor module 20. That is, as an example, in the case of a USB camera, video data may be directly transmitted to the control computer 210 without passing through the controller 20. In the case of passing through the controller 20, the communication unit includes a USB terminal suitable for the USB camera. Should be If a network camera, a network capable configuration may be provided.

When the communication unit 21 of the controller communicates with other devices wirelessly, an infrared sensor may be used. That is, when the communication unit 21 transmits an infrared signal for turning on / off the operation of the fan, the infrared receiver attached to the fan may receive the signal to control the operation of the fan. However, since the infrared signal has a short distance and directionality, in this case, a ZigBee capable of 1: N communication may be used. The infrared signal or the Zigbee method may be appropriately selected depending on the installation environment.

The projector 15 of the above-described power consumption device 10 may cause damage to the lamp if the power is simply cut off, so the power should be safely turned off. Therefore, the present invention uses the power on / off signal of the remote control output from the remote control of the projector. Since the remote control signal mostly uses an infrared signal, the communication unit 21 of the controller 20 includes a module capable of transmitting an infrared signal to transmit a power on / off control command of the projector to the projector.

However, the remote control power on / off signal of the projector differs in the frequency of the remote control signal for each manufacturer. Therefore, by acquiring the remote controller frequency signal of such a projector by manufacturer and setting it by using a dip switch according to the installation environment, the controller recognizes what kind of projector and outputs an on / off control signal according to the projector. It can cope more smoothly with various kinds of.

In addition, a signal of a power switch attached to the front of the computer is used to safely turn off the power of the computer 14 provided in each partitioned space. The power switch on the front of the computer sends a signal to the motherboard when a person pushes it, turning the computer off safely. In this way, a power on / off control command transmitted from the controller 20 by additionally attaching an infrared module or a Zigbee module on the main board of the computer (these control commands are generated when pushed by a power switch attached to the front of the computer). The computer can be safely turned off by receiving a signal that will generate a signal identical to the signal).

Meanwhile, when the controller 20 stores the signal from the camera module 34, a memory for storing the signal from the camera module 34 is additionally provided, and the occupancy determining unit 22 extracts a still image of a necessary part of the video signal from the memory. It is also possible to determine whether a person is occupied. If the controller 20 simply transmits the signal from the camera module 34 to the control computer 210 without processing the signal, the design specification of the controller may be lowered and the compact controller may be implemented by reducing the burden on the controller. This will be possible.

When the control computer 210 analyzes the video signal and detects whether or not the room is occupied, the control unit 210 transmits the analysis result to the room determining unit 22 of the controller, and the room determining unit 22 transmits the power to the device controller 23 for power consumption. The related content can be delivered to generate a control signal.

On the other hand, the air-conditioning system of a general building is classified into central control and individual control. In the case of individual control, the same method as in FIG. 2 may be used. In the case of central control, hot and cold air is introduced into a lecture room through duct pipes. Do it. Therefore, in the case of central control, a damper for controlling the air flow in the duct pipe may be installed. In this case, a voltage analog output function may be added to output a DC voltage to drive the damper.

In addition, to control the heating and cooling energy of the building, the room temperature must be measured. Therefore, a number of temperature sensors can be installed in various locations according to the size of the classroom or the needs of the lecture room. The controller 20 may determine this.

The controller 20 operates the power consumption device separately from the human body detection signal input from the sensor module at a current time, vacation period, or time and condition forbidding the use of energy by the energy integrated management computer 300. Can be prohibited.

The power consumption device controller 23 generates a command for controlling the operation of each power consumption device 10 based on the data input from the occupancy determination unit 22, and consumes the power through the communication unit 21. To the device 10. The power consuming device controller 23 may know which power consuming device 10 has started to operate and when the power is turned off. Accordingly, the power usage data of the power consumption device 10 is transmitted to the control computer 210, and the control computer 210 transmits it back to the energy integrated management computer 300 so that the energy integrated management computer 300 can Allow energy management.

The room determination unit 22 and the power consumption device control unit 23 of the controller 20 are divided for convenience of explanation of each unit and may be implemented by digital and analog circuits.

The communication unit 240 of the control computer 210, 220, 230 according to the present invention transmits a command transmitted from the energy integrated management computer 300 to the controller 20. In addition, the controller 20 processes the video data transmitted through the controller 20. As described above, the moving image data may be processed by the controller 20 or may be processed by the control computer. When the control computer processes, a storage unit 250 capable of storing moving image data is added, and the data processing unit 260 extracts moving image data stored in the storage unit as a still image and detects a human body in a classroom.

The control computer may be provided one by one in each of the partitioned spaces, or may be provided in bundles of several partitioned spaces. Such a control computer may be a general notebook computer, desktop computer, tablet PC, personal digital assistant. The storage unit 250 is preferably a memory having a sufficient storage space, such as a hard disk, SSD memory.

The integrated energy management computer 300 according to the present invention receives the data related to the use of energy from the control computer (210,220,230) installed in each partitioned space to manage the energy use and, if necessary, commands to ban the use of energy. Transfer to the control computer.

If the air conditioner described above is made of central control and a human body is detected, if the current temperature of each classroom is higher than the set temperature, the controller 20 requests cooling to the control computer 210, and the control computer 210 supplies energy. After receiving a request for cooling to the integrated management computer 300 and receiving the approval, the controller may generate a control signal for cooling. This procedure is equally applicable to a heater with central control.

The energy integrated management computer 300 classifies the case where the energy use used in each partitioned space is not reserved or is not reserved, and approves and monitors the energy use. When the energy is used due to a special situation or an urgent situation other than the predetermined time when not scheduled, when the controller 20 requests the integrated energy management computer 300 from the controller 20 to request the integrated energy management computer ( 300 determines whether the energy use is permitted and transmits a use approval or rejection signal to the controller.

As another example, when energy use is reserved, when the predetermined time is reached, the controller 20 recognizes the time and turns on the operation of the power consumption device 10, and provides data on energy use of the integrated energy management computer 300. To send.

The integrated energy management computer 300 continuously monitors the amount of energy consumed by the power consumption device 10 and transmits an energy use permission or prohibition command to the controller in accordance with the determined amount. In addition, the amount of power used in each partitioned space may be managed for each partitioned space. That is, the electricity consumption of the computer room and the electricity consumption of the lecture room can be determined differently, and in the case of the computer room, the electricity consumption of the different computer rooms can be determined differently. As for the method of calculating the strategy usage used in the present invention, various conventional techniques and methods may be used.

(Human detection method)

The controller 20 or the control computer 210, 220, or 230 detects the human body using the signal generated by the sensor module 30 described above. However, in order to prevent malfunction of the voice recognition sensor module, the infrared sensor module, and the hot wire sensor module, the human body detection method is supplemented by using a video photographed by the camera module 34.

The method of detecting the human body using the captured video may be performed by the controller 20 or the control computers 210, 220, and 230. As an example, when the control computer detects a human body, a video captured by the camera module 34 may be wired (eg, LAN or USB) or wireless (eg, a communication protocol capable of 1: n communication such as Wi-Fi / ZigBee). It is input to the controller 20 through. The controller 20 transmits the input video data back to the control computer 210 through wired (eg LAN) or wireless (eg Wi-Fi / Zigbee communication protocol) communication. The control computer 210 stores the received video data and detects the human body using a still image extracted at a predetermined time from the stored video data.

As shown in FIG. 3, each still image 40 is a still image extracted with different extraction time from moving image data. Still images are extracted approximately every 30 seconds to one minute. The still images 41, 42 and 43 are images when no person enters or exits the classroom. The still image 44 is an image when a person enters and leaves the initial or some time. At this time, whether or not a person enters or exits the lecture room is recognized by extracting the shape of the human body.

In the present invention, the still image 43 (t3 extracted at t3) when there is no person before the still image 44 (t4 extracted) at which a person enters and exits becomes a basic still image. When the basic still image is set, the image is compared with the still images 44 to 47 extracted after the basic still image. Accordingly, the basic still image 43 and the comparison still image 44, 45, and 46 are compared with each other, and since a person exists, the basic still image 43 and the comparison still image 44, 45, and 46 are different from each other. There will be a difference.

Since the comparison still image 47 is compared with the basic still image 43 is determined that there is no difference between each other, therefore, it is possible to appropriately control the operation of the power consumption device 10 by recognizing that there are no people in the classroom. . However, as described above, the human body detection signal by the still image analysis may be complemented with the human body detection signal generated by another sensor module to accurately determine whether the human body is lost.

In the above-described basic still image 43, the position of a desk or an object other than the human body that is placed in a lecture room may be changed according to a person's entrance and exit. Therefore, the basic still image 43 extracted at time t3 may be changed to the basic still image 47 extracted at time t7 later. In this way, even if a person enters or exits again, the difference between the image of the lecture room where the location of the object is changed and the image of the new person can be compared to each other to classify the difference between the video images.

Although the present invention has been described with reference to the embodiment thereof, the present invention is not limited thereto, and various modifications and applications are possible. In other words, those skilled in the art can easily understand that many variations are possible without departing from the gist of the present invention.
