Description

  The present invention relates to an in-building control system that can automatically control various electric devices in a building such as a house.

  Conventionally, in buildings such as houses, there is a technology that detects the presence of people by human sensors at the entrance and stairs in the building, and automatically turns on lighting fixtures when a person is detected. Proposed. Various types of lighting fixtures and the like in which human sensors are integrated have also been proposed (see, for example, Patent Document 1). However, with existing technology, there is a one-to-one relationship between a human sensor and a device such as a lighting fixture that is automatically controlled by the sensor, and lacks expandability when attempting to realize automatic control in a house. There was a problem.

In addition, for example, a technique of laying a LAN cable in a house and automatically controlling various electric devices via the LAN cable has been studied. However, in order to realize automatic control using the LAN cable, it is necessary to newly lay the LAN cable so as to pass through the wall of the house, which takes time and cost for practical use. Problems arise. In recent years, it is thought that improvement of automatic control technology in buildings is greatly expected from the background of increasing interest in energy saving and crime prevention.
JP 2005-235398 A

  The main object of the present invention is to provide an in-building control system that can be put into practical use in a relatively simple manner and that can realize highly scalable in-building control.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, in order to facilitate understanding, a corresponding configuration example in the embodiment of the invention is appropriately shown in parentheses, etc., but is not limited to the specific configuration shown in parentheses.

  In the in-building control system of the present invention, a human sensor (human sensor 22) that detects the presence or absence of a person in a building such as a house, and various electric devices (lighting fixtures) that operate by feeding power through a power line (power line 33). 15, air conditioner 16, etc.). Then, using the power line as a transmission medium for communication information, the detection information of the human sensor is transmitted to the electric device through the power line, and the electric device is caused to perform automatic control according to the detection information.

  According to this configuration, it is possible to automatically control electric devices according to the presence or absence of a person in the building for a plurality of electric devices, and to improve convenience in the building. At this time, it is possible to enhance the energy saving effect and the crime prevention effect. In addition, it is not necessary to provide a human sensor for each electric device. Furthermore, since the power line is used as a transmission medium, desired in-building control can be realized while diverting general facilities in the building. That is, in performing the control, a new facility such as a LAN cable is not required as an information transmission medium. At this time, it is possible to control various devices connected to the power lines in the building (for example, AC 100V wiring). As described above, in-building control that can be put into practical use relatively easily and has high expandability can be realized.

  A human sensor may be provided integrally with the power outlet (outlets 17 to 19). Thereby, the human sensor becomes inconspicuous, and the human sensor can be installed without causing a sense of incongruity in the design in the building. For example, when a human sensor is installed alone on a ceiling or the like, not only is it conspicuous, but extra wiring and installation work are required, but this configuration can eliminate such inconvenience. In addition, the configuration for supplying power to the human sensor can be simplified by integration with the power outlet.

  In a room provided in a building, a human sensor may be installed so that the detection area includes the entrance / exit of the room (entrance 12). Thereby, the person who goes in and out of a room can be detected reliably, and the electric equipment which wants to operate according to the person in and out of a room can be controlled suitably.

  On the other hand, it is also possible to use a communication method other than power line communication as the communication method, in which case the following configuration is desirable. Note that the communication means includes wireless communication in addition to wired communication such as LAN.

  That is, a human sensor (human sensor 22) is provided integrally with a power outlet (outlets 17 to 19) installed in a room of a building, and the presence / absence of a person is detected by using the human sensor as a detection area. Is detected. Then, the detection information of the human sensor is transmitted to various electrical devices (such as the lighting fixture 15 and the air conditioner 16) in the building by communication means, and each electric device performs automatic control according to the detection information of the human sensor. .

  According to this configuration, as in the above configuration using power line communication, automatic control of electrical devices can be performed according to the presence or absence of people in the building for a plurality of electrical devices, Convenience can be improved. In particular, since the entrance / exit of the room is included as the detection area of the human sensor, it is possible to reliably detect the person entering / exiting the room, and it is possible to suitably control the electric device to be operated according to the person entering / exiting the room. At this time, it is possible to enhance the energy saving effect and the crime prevention effect. In addition, it is not necessary to provide a human sensor for each electric device.

  In addition, since the presence sensor is integrated with the power outlet, extra wiring and installation work can be eliminated compared to the case where the presence sensor is installed on the ceiling alone. The configuration for power supply can be simplified. Further, the human sensor becomes inconspicuous, and the human sensor can be installed without causing a sense of incongruity in the design in the building. As described above, in-building control that can be put into practical use relatively easily and has high expandability can be realized.

  Further, in the building control system further provided with an opening / closing sensor (door opening / closing sensor 36) for detecting opening / closing of the door (door 13), the detection information of the opening / closing sensor is transmitted to the electric device, and the detection information of the human sensor It is preferable to perform automatic control of the electric device according to the detection information of the open / close sensor. In such a case, according to the detection information of the human sensor (human sensor installed so that the entrance of the room is included in the detection area) and the detection information of the open / close sensor, not only the presence of a person in the room but also the person It is possible to determine whether the user has entered the room or has left the room (entrance / exit determination can be performed). Specifically, it is determined whether a person has entered the room or a person has left the room based on the order of the human detection by the human sensor and the opening detection of the door or the like by the opening / closing sensor.

When a plurality of people use a room, it is possible that another person remains in the room even if it is detected that one person has left the room. Therefore, in the room, a human sensor (for example, a human sensor having the entire room as the detection area) including the detection area other than the entrance of the room is separately installed, and the human sensor for detecting the entrance / exit Even if it is detected, if a person is detected by a human sensor for detection other than the entrance / exit, it may be determined that a person remains in the room. Thereby, it is possible to suppress malfunctions of the electric devices such as the lighting fixtures being turned off even if a person remains in the room.

  By the way, if it is determined that there are no people left in the room based on the detection information of both the human sensor for entrance and exit detection and the human sensor for detection other than the entrance and exit, turn off the power to each electrical device. Is automatically performed.

  For example, in a house, there may be a case in which a toilet or a bathroom is a detection target room and the presence or absence (that is, usage status) of a person in the room is desired to be monitored from the outside. In such a case, a display device (presence / absence display device 39) for displaying the result of the human detection is provided in a room different from the room in which human detection is performed by the human sensor. Then, it is preferable that the detection information of the human sensor or the person's entry / exit information determined based on the detection information is transmitted to the display device, and the display device displays the result of the human detection based on the detection information or the like. As a result, the room status can be monitored from the outside of the room to be detected.

  Further, in the building control system provided with the computer device (the personal computer 37), the computer device is based on the detection information of the human sensor received each time or the person's entry / exit information determined based on the detection information. It is good to start automatically. This improves the convenience of using the computer device. In addition, when the computer apparatus is activated, various processes mainly performed by the computer apparatus can be automatically executed.

  The computer device may sequentially store the detection information of the human sensor or the information of the person coming and going based on the detection information in the storage device. Thereby, the history of the detection information of the human sensor can be stored, which can be used for later confirmation and analysis. Specifically, with respect to detection information of the human sensor, the time of human detection, the staying time of a person in a room, the number of detections, and the like may be stored sequentially.

  The computer device may read and display the stored information in the storage device on condition that authentication information such as a password is input. As a result, the stored information cannot be read unless the password or the like is input correctly, and information management can be performed appropriately.

  In an in-building control system having a security device having a warning function (security setting device 38), the security device detects the detection information of the human sensor received each time or the person determined based on the detection information. A warning or the like is executed based on the in / out information. As a result, when a person enters or leaves a room or the like, it is possible to take measures according to the security mode, security level, etc.

  It is also possible to apply the building control system of the present invention to an apartment house such as an apartment or a condominium. In such a case, the detection information of the human sensor (human sensor 57) or the person's entry / exit information determined based on the detection information is transmitted to the power supply device (distribution panel 51) provided for each residence. To do. And based on this detection information etc., it is good for an electric power supply apparatus to implement switching with an electric power supply state and an electric power interruption state. According to this configuration, for example, when an administrator or the like enters a vacant house and performs an inspection, the power supply device automatically enters the power supply state (the distribution board breaker is automatically set). Go up). In addition, after the vacant room is inspected, the power supply device automatically turns off the power (the distribution board breaker automatically drops). Therefore, it becomes possible to easily check an empty room.

Further, in the apartment house, a human sensor (human sensor 63) provided near the door (door 62) of the common entrance (common entrance 61) and a warning device (suspicious person warning device 64) having a warning function. Can be communicated between them. When the human sensor detects a person with a predetermined time difference and the time difference is within a specified time, the warning device may issue a warning. Accordingly, it is possible to detect and warn a suspicious person (so-called accompanying person) who tries to enter the apartment house following the resident or the like.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing one of rooms in a house to which the present invention is applied.

  In FIG. 1, a room 10 is surrounded on all four sides by walls 11, and an entrance 12 is provided in one of the walls 11, and a door 13 that opens and closes the entrance 12 is provided. By opening the door 13, a person can enter or leave the room 10. The door 13 may be a sliding door as well as a door-shaped one as shown.

  The room 10 is provided with a plurality of electric devices. Specifically, a lighting fixture 15 is attached to a ceiling (not shown), and an air conditioner 16 as an air conditioner is attached near the ceiling of the wall 11. Near the floor surface of the wall 11, a power outlet 17 for supplying power to various home appliances used in the room 10 is provided. Similarly, a power outlet 18 for supplying power to the air conditioner 16 is provided near the air conditioner 16 on the wall 11. The room 10 is further provided with a power outlet, which is omitted in FIG. Hereinafter, the power outlet is also simply referred to as an outlet.

  Here, the outlets 17 and 18 have a power detection function as a main function in the same manner as the conventional outlets, and also have a human detection function for detecting the presence or absence of a person in the room 10. As shown in FIG. As shown in FIG. 2, the outlets 17 and 18 are provided with two upper and lower plug insertion ports 21 and a human sensor 22. The human sensor 22 includes a sensor element 23, and the front of the sensor element 23 is covered with a convex cover 24. The human sensor 22 is a sensor module that detects the presence of a person using infrared rays or the like and outputs an electrical signal corresponding to the detection result.

  In the present embodiment, the human sensor 22 provided in the outlets 17 and 18 detects a person who enters and exits as the door 13 opens and closes through the doorway 12. The detection areas of the outlets 17 and 18 are as follows. It is set to include at least the vicinity of the entrance 12. In other words, the above-described outlets 17 and 18 with human sensors are installed at a part where the entrance and exit of a person through the entrance 12 can be detected. In this case, it is assumed that furniture or the like is placed in the room 10. Therefore, it is desirable to install more outlets with human sensors in order to reliably detect the entrance and exit of people through the entrance 12.

  FIG. 3 is a schematic diagram showing a sensor detection area in the room 10. For example, in a room of about 6 tatami mats, about three outlets are generally provided. In FIG. 3, an outlet 19 with a human sensor is added in addition to the outlets 17 and 18 described above. R1, R2, and R3 in the figure are detection areas of the human sensor 22 in each of the outlets 17 to 19.

In FIG. 3, the sensor detection areas R <b> 1 to R <b> 3 of the outlets 17 to 19 are all set to include the vicinity of the entrance / exit 12 of the room 10, and the entrance / exit is performed by at least the human sensor 22 of the outlets 17 to 19. The person who goes in and out through 12 can be detected. Incidentally, as shown by a virtual line in FIG. 3, when furniture 25 or the like is placed along the wall 11, it becomes an obstacle and human detection by the human sensor 22 becomes impossible (here, The person detection at the outlet 17 becomes impossible), and the reliability of the person detection is improved by providing outlets with human sensors at a plurality of locations.

  Further, in this embodiment, a home control system is constructed by a home communication network using power line communication (PLC), and various home appliances in the home are exchanged by exchanging various information via the power line. Various control-related and security-related operations are realized. In particular, here, lighting devices, air conditioners, and the like are controlled based on human detection information transmitted from an outlet with a human sensor. A system in which the electrical facilities in the house are controlled in an integrated manner is also called a home automation system.

  FIG. 4 is a diagram showing a schematic configuration of the in-house control system. In this system, electric power is drawn into the distribution board 32 provided in the house through the lead-in line 31, and the electric power is distributed and supplied to each part in the house by the distribution board 32.

  In the house, a power line 33 for supplying power (AC 100V power) to various home appliances is provided, and various home appliances operate by power supply through the power line 33. A plurality of PLC modems 34 are connected to the power line 33. The PLC modem 34 is an adapter for power line communication. The PLC modem 34 superimposes or separates power and communication signals. In this example, as described with reference to FIG. 1 and the like, the lighting device 15 and the air conditioner 16 are provided as household appliances, and the outlets 17 and 18 with human sensors are provided, which are the power line 33 and the PLC modem. 34 are connected to each other via 34. Reference numeral 35 denotes an AC-DC adapter that converts AC power into DC power, and a DC voltage is applied to the human sensor 22 via the AC-DC adapter 35.

  The luminaire 15 and the air conditioner 16 have an automatic control function that executes control in a timely manner based on communication information by power line communication. The luminaire 15 and the air conditioner 16 have a control unit for performing automatic control. Built in. In the lighting fixture 15, switching of lighting / extinction, illuminance adjustment, etc. are suitably performed based on the communication information by power line communication. In the air conditioner 16, ON / OFF switching, set temperature adjustment, air volume adjustment, wind direction adjustment, and the like are appropriately performed based on communication information through power line communication.

  In addition, in this house, a door opening / closing sensor 36 that detects opening / closing of the door 13 in the room 10, a personal computer 37 having a data server, a security setting device 38 that performs various security-related settings, and the presence / absence of people in the room 10 A presence / absence display device 39 for displaying absence, a power shut-off device 40 for automatically shutting off standby power for TVs, audio devices, and the like are provided, and these are connected to the power line 33 via the PLC adapter 34, respectively. ing. The door opening / closing sensor 36 is, for example, a magnet type sensor. When the door opening / closing sensor 36 detects the opening / closing of the door 13, the detection information flows on the power line network.

  In this system, in addition to detecting the presence of a person near the door based on the detection information of the human sensor 22, a person enters or leaves the room based on the detection information of the human sensor 22 and the door opening / closing sensor 36. Is determined. At this time, the entrance / exit of a person is determined according to the order of the person detection by the human sensor 22 and the door opening detection by the door opening / closing sensor 36. Then, the lighting fixture 15 and the air conditioner 16 are controlled in accordance with the determination result of the entrance / exit.

  Next, calculation processing executed by a control unit such as the lighting fixture 15 or the air conditioner 16 will be described. FIG. 5 is a flowchart showing an outline of the calculation process.

  FIG. 5A shows a main routine executed by the control unit such as the lighting fixture 15 or the air conditioner 16 at a predetermined time period, for example. In this routine, an entrance / exit determination process is executed in step S10, and an automatic control process is executed in step S20. (B) and (c) of FIG. 5 are subroutines of steps S10 and S20. In addition, the automatic control process in the lighting fixture 15 is shown here in FIG.5 (c).

  5B, in step S11, it is determined whether or not a person is detected near the door (near the entrance / exit) of the room 10 based on the detection information of the human sensor 22, and in step S12, the door is opened or closed. Based on the detection information of the sensor 36, it is determined whether or not the door 13 is opened. At this time, if both of steps S11 and S12 are YES, the process proceeds to the subsequent step S13, and if any of steps S11 and S12 is NO, the process is terminated.

  In step S13, it is determined whether the human detection by the human sensor 22 and the door opening detection by the door opening / closing sensor 36 are performed in the order of “human detection → door opening detection”. If the detection order is “person detection → door opening detection”, the process proceeds to step S14, and it is determined that a person has left the room 10 (exit determination). Conversely, if the detection order is “door open detection → person detection”, the process proceeds to step S15, and it is determined that a person has entered the room 10 (room entry determination).

  On the other hand, in FIG. 5C, in step S21, it is determined whether or not a room entry determination has been made before the current process, and in step S22, it is also determined whether a room exit determination has been made prior to the current process. . If the room entry determination is made, the process proceeds to step S23, and the power supply to the light source unit is turned on. Thereby, the lighting fixture 15 is turned on automatically. If it is determined that the user has left the room, the process proceeds to step S24, and the power supply to the light source unit is turned off. Thereby, the lighting fixture 15 is automatically turned off. In addition, when neither entry determination nor exit determination is made, the ON / OFF operation of the light source unit is not performed.

  However, the automatic control content described in FIG. 5C is merely an example and can be changed. For example, the light source part of the luminaire 15 may be basically turned on (power-on state), and the illuminance may be increased when entering the room and the illuminance may be reduced when leaving the room. In this configuration, it is preferable to turn off the power supply to the light source unit when a predetermined time has elapsed after the exit determination is made.

  Although detailed description is omitted, automatic control is also executed in the air conditioner 16 in accordance with the result of the entrance / exit determination. For example, when the entry determination is made by the entry / exit determination process, the power of the air conditioner compressor or the like is turned on (that is, the air conditioner is operated), and when the exit determination is made, the power of the air conditioner compressor or the like is turned off. (Ie the air conditioner is shut down). It is also possible to increase the air conditioner output when entering the room and to reduce the air conditioner output when leaving the room.

  When the entrance / exit determination of the room 10 and the automatic control of the electric device are performed as described above, the entry / exit determination history and the operation history of the electric device are managed by the personal computer 37.

Specifically, when it is determined that a person has entered the room based on the detection information of the human sensor 22 or the door opening / closing sensor 36 in the control unit of one of the electric devices such as the lighting fixture 15 and the air conditioner 16, The determination result is transmitted to the personal computer 37 through the power line 33, and the received determination result is stored in the memory. Similarly, information related to the operation status of each electric device is transmitted to the personal computer 37, and the received information is stored in the memory. Thereby, the history of the person's entry / exit and the operation history of how each electric device is operated are stored together with the time data. As data stored in the memory, the staying time of the person in the room, the number of person detection integrations, which sensor among the plurality of human sensors, etc. may be stored.

  The personal computer 37 has a built-in (or attached) automatic starter, and the result of entry / exit determination is transmitted to this automatic starter. If the personal computer 37 is not activated when it is determined that a person has entered the room, the personal computer 37 is immediately activated by the automatic activation device.

  However, in addition to the configuration in which the result of entrance / exit determination is transmitted from the lighting fixture 15 or the air conditioner 16 to the personal computer 37, the personal computer 37 itself enters / exits based on the detection information of the human sensor 22 and door opening / closing sensor 36. A configuration in which a determination process is executed may be used. In short, the entry / exit determination process may be performed for each device that receives the detection information of the human sensor 22 and the door opening / closing sensor 36, or the entry / exit determination process is executed in any specific device, and the determination result is It may be transmitted to other devices. The configuration may be such that the entrance / exit determination process is performed only on the personal computer 37 on the condition that the personal computer 37 is always activated.

  The personal computer 37 may start a separate server device (recording device) and store a determination result or the like in the server device. The server device continues to record various types of information until it is determined that the person has left the room, and the operation is stopped after it is determined that the person has left the room.

  Information stored in the memory of the personal computer 37 (or information stored in the server device) is read out on condition that an identification code, a personal identification number (password), or the like is input, and displayed on the display of the personal computer 37 or the like. It has become. That is, an unauthorized person cannot read the stored information without permission.

  Also, in the security setting device 38, the presence / absence display device 39, the power shut-off device 40, and the like, predetermined processing is performed based on the result of the room entry / exit determination with respect to the room 10. Details are described below.

  The security setting device 38 transmits the detection information of the human sensor 22 and the door opening / closing sensor 36 or the result of the entrance / exit determination processing executed by each device through the power line 33, and the security setting device 38 Depending on the detection information and the result of entry / exit determination, warning processing, security settings, etc. are executed. In this case, the security setting device 38 has a warning function using a lamp, voice, or the like, and when it is determined that a person has entered the room, a warning using a lamp, voice, or the like according to the security mode, security level, etc. It is good to activate. It is also possible to automatically lower the security level when it is determined that a person has entered the room and to automatically increase the security level when it is determined that a person has left. For example, the warning mode is canceled when the person enters the room, and the warning mode is set when the person leaves the room.

  The presence / absence display device 39 is used when, for example, a toilet or a bathroom is a detection target and the detection result is monitored in a living room or the like. The display device 39 is embodied by, for example, a liquid crystal display device that can arbitrarily display characters, symbols, and the like. However, a device that displays with a lamp or the like may be used.

The presence / absence display device 39 transmits the detection information of the human sensor 22 and the door opening / closing sensor 36 or the result of the entrance / exit determination processing executed by each device through the power line 33, and the presence / absence display device 39 The display output corresponding to the detection information of each sensor and the result of the entrance / exit determination is performed. For example, when it is determined that a person has entered the room, or when it is determined that a person has left the room, display corresponding to each is executed. For simplicity, the presence indicator lamp is turned on when it is determined that a person has entered the room, and the presence indicator lamp is turned off when it is determined that the person has left the room. When displaying, it is also possible to combine sound and the like.

  The power shut-off device 40 is for suppressing unnecessary power consumption for energy saving when no person is present in the room 10. The detection information of the human sensor 22 and the door opening / closing sensor 36 or the result of the entrance / exit determination process executed by each device is transmitted to the power shut-off device 40 through the power line 33, and the power shut-off device 40 detects the detection of each sensor. The standby power source of the television or audio equipment is shut off according to the information and the result of the entrance / exit determination. For example, when it is determined that a person has entered the room, the standby power is shut off, and when it is determined that the person has left, the standby power is turned on. However, items that should be constantly supplied with power, such as refrigerators, are excluded from the targets of power shutoff by the power shutoff device 40.

  As described above, each electrical device (lighting fixture 15, air conditioner 16, etc.) installed in the room has an automatic control function using power line communication, but the automatic control function is enabled or disabled. A selection means (ON / OFF switching means) for selecting is provided for each device. In this case, in a state where the automatic control function is turned off by the user's operation, even if a person enters the room, automatic control is not performed in each electric device in cooperation with the person.

  By the way, when a plurality of people use the room 10, there may still be people remaining in the room even if one person leaves the room. Therefore, as a countermeasure, human detection is performed in the detection area other than the vicinity of the door, and automatic control of the lighting fixture 15 and the like is performed in consideration of the detection information.

  Also in this configuration, it is desirable to use a human sensor with an outlet integrated. Therefore, out of a plurality of outlets installed in the room 10, outlets that are convenient for detecting people near the door are for detecting people near the door, and outlets that are not convenient for detecting people near the door. Is for human detection of the entire room. At this time, in order to ensure detection accuracy, it is desirable to provide a plurality of outlets with human sensors for detecting people near the door and a plurality of outlets with human sensors for detecting people in the entire room. However, when the entire room is used as a detection area, for example, a human sensor may be provided in a lighting fixture attached to the ceiling so that the person in the room is detected from a high level.

  In the entrance / exit determination process executed by the control unit such as the lighting fixture 15 or the air conditioner 16, even when the person's exit is determined by the human sensor 22 for detecting the vicinity of the door or the door opening / closing sensor 36, the entire room is detected. When it is determined by the human sensor that a person remains in the room, an operation such as turning off the lighting fixture 15 or stopping the operation of the air conditioner is not performed. According to this configuration, even when a plurality of people enter and leave the room, automatic control of the lighting fixture 15 and the air conditioner 16 can be suitably performed.

  According to the embodiment described above in detail, the following excellent effects can be obtained.

  Since the power line 33 is used as a transmission medium for communication information, detection information of the human sensor 22 is transmitted to each electric device through the power line 33, and automatic control according to the detection information is performed in the electric device. Therefore, it is possible to perform suitable automatic control for the electric appliances, and it is possible to improve convenience in the house. At this time, it is possible to enhance the energy saving effect and the crime prevention effect. In addition, it is not necessary to provide the human sensor 22 for each electric device. Furthermore, since the power line 33 is used as a transmission medium, desired in-house control can be realized while diverting general equipment in the house. That is, in performing the control, a new facility such as a LAN cable is not required as an information transmission medium. As a result, it is possible to realize practically easily controlled housing control with high expandability.

  Since the human sensor 22 is provided integrally with the power outlets 17 to 19, the human sensor 22 becomes inconspicuous, and the human sensor 22 can be installed without causing a sense of incongruity in the house. Further, the configuration for power supply to the human sensor 22 can be simplified by integration with the power outlets 17 to 19.

  Incidentally, an outlet tap with a sensor integrated with a human sensor has already been disclosed as a patent document (Japanese Patent Laid-Open No. 2003-331995). However, in the case of such a technique, devices that can be controlled are limited to devices connected to an outlet tap (outlet outlet) such as a lighting fixture, and there is a problem of lack of expandability. If, for example, a fork outlet tap is further connected to the outlet, two or more electrical devices can be controlled simultaneously by the detection signal from the human sensor. In the same way, it is controlled in the same way, and it still lacks extensibility. On the other hand, according to the present embodiment, it is possible to arbitrarily control a plurality of electric devices connected to the power line 33.

  Since the human sensor 22 is installed so that the entrance / exit 12 of the room is included in the detection area, it is possible to reliably detect a person entering and exiting the room, and it is possible to suitably control an electric device to be operated according to the person entering and exiting the room.

  Using the detection information of the human sensor 22 and the detection information of the door opening / closing sensor 36, not only the presence / absence of a person in the room, but also a determination (entrance / exit determination) whether a person has entered the room or has left the room. Since it did in this way, it becomes possible to control electric equipment more appropriately.

  Moreover, in addition to the human sensor 22 for detecting the vicinity of the door as the human sensor, the human sensor for detecting the entire room can be used to suitably detect the person even in a room used by a large number of people. it can. Therefore, it is possible to suppress malfunctions of the electric devices such as the lighting fixture 15 being turned off even though a person remains in the room.

  Since the presence / absence of a person is detected in the toilet / bathroom and the like, and the result is displayed on the presence / absence display device 39, the usage status of the toilet / bathroom can be grasped while staying in the living room. it can.

  The personal computer 37 is automatically started based on the detection information of the human sensor 22 or the determination result (entry / exit determination result) corresponding to the detection information, and the detection information and the like are sequentially stored in a memory or the like. The stored information can be used for later confirmation and analysis. In addition, since information stored in a memory or the like is read out on condition that authentication information such as a password is input, information management can be appropriately performed.

  The security setting device 38 issues a warning or changes the security level based on the detection information of the human sensor 22 or the determination result (result of entering / exiting determination) corresponding to the detection information. A system with high crime prevention can be realized by monitoring.

  Since the power shut-off device 40 automatically shuts off the standby power source of the television or audio equipment based on the detection information of the human sensor 22 or the determination result (result of entrance / exit determination) corresponding to the detection information, useless power consumption And energy saving can be promoted.

(Second Embodiment)
In the present embodiment, a specific example will be described assuming that the in-building control system of the present invention is installed in an apartment house such as an apartment or a condominium.

  As shown in FIG. 6, the apartment house 50 is provided with a plurality of residences (residences A to F in the figure), and a distribution board 51 is provided for each residence. Each distribution board 51 is provided with a breaker device 52. The distribution board 51 is connected to an electric device 54 (such as a lighting fixture or an air conditioner) in each residence through a power line 53. In each of the residences A to F, power line communication using the power line 53 as an information transmission medium is performed as in the above-described embodiment. In this case, the breaker device 52 and the electric device 54 are individually provided with a PLC modem (power line communication adapter) and a control unit, but the illustration is omitted here.

  In addition, each residence A-F is provided with an outlet-integrated human sensor 57 in the vicinity of the entrance door 56, and detection information of the human sensor 57 flows on the communication network through the power line 53. The detection area of the human sensor 57 is set to a range in which a person entering and exiting at least through the front door 56 can be detected. The configuration of the outlet with the human sensor 57 integrated is the same as in FIG. In such a case, the human detection information by the human sensor 57 is transmitted to the distribution board 51 and the electric device 54 through the power line 53, and the distribution board 51 and the electric device 54 determine the presence / absence of a person in the residence. Is done. Then, based on the determination result of the presence / absence of a person, automatic control is performed by the distribution board 51 and the electric device 54, respectively. A door opening / closing sensor may be provided on the entrance door 56, and the presence / absence of a person in the residence may be determined based on the detection information of the human sensor and the detection information of the door opening / closing sensor.

  Here, in the apartment house 50, since the vacant house is not normally used, the breaker device 52 is in a power cut-off state for energy saving and maintenance. Therefore, when an administrator or the like performs an inspection or the like in a vacant house, first, the breaker device 52 must be operated to be in a power supply state. At night, for example, operations in the dark are forced, and the workability is poor.

  In this regard, in the present embodiment, when the manager or the like opens the entrance door 56 and enters the residence, the manager or the like is detected by the human sensor 57, and the breaker device 52 is automatically operated to power. Transition to the supply state is performed (breaker ON). Further, when an administrator or the like has left the residence, this is detected by the human sensor 57 and the power is cut off by the breaker device 52 (breaker OFF). As a result, an administrator or the like can save the trouble of operating the breaker device 52, and work such as vacant room inspection can be easily performed.

  In a vacant room of the apartment house 50, when human detection is performed by the human sensor 57 or the like, the detection information may be transmitted to the electric device 54 through the power line 53, and the electric device 54 may perform various controls based on the information. . For example, lighting fixtures can be turned on automatically, crime prevention devices such as crime prevention lamps and security buzzers can be activated, or the information can be sent to a management PC owned by an administrator and stored in a storage device. It is.

  As described above, an automatic control function using power line communication is added to the distribution board 51 and the electric device 54 in each of the houses A to F, and it is selected whether to enable or disable the automatic control function. Each of the selection means (ON / OFF switching means) is provided. In this case, in a state where the automatic control function is turned off by the user's operation, even if a person enters the room, automatic control by the distribution board 51 or the electric device 54 is not performed in cooperation with the person. It has become. For example, after a borrower appears in a house that is an empty room, the automatic breaker automatic ON / OFF function in the distribution board 51 may be stopped.

On the other hand, it is also possible to introduce this control system as a monitoring system for a common entrance in an apartment house having a common entrance such as a large apartment. In other words, in general, various security systems are adopted so that only residents and those who have obtained consent from the residents can open the door or unlock the door to enter the common entrance. However, before a resident or the like enters the apartment and the door is closed or locked again, a suspicious person enters the apartment following the resident or the like (also referred to as a companion).

  The countermeasure against the suspicious person will be described below. As shown in FIG. 6, the apartment house 50 is provided with a common entrance (entrance) 61, and a warning sensor 63 is provided near the door 62 of the common entrance 61, with an outlet-integrated human sensor 63, a lamp, voice, and the like. A suspicious person warning device 64 is provided. The human sensor 63 and the suspicious person warning device 64 are connected to the power line 65, and power is supplied through the power line 65. Similarly, the human sensor 63 and the suspicious person warning device 64 can communicate with each other through the power line 65. It has become. At this time, the detection area of the human sensor 63 is set to a range in which a person entering and exiting at least through the door 62 of the common entrance 61 can be detected. The configuration of the outlet integrating the human sensor 63 is the same as that in FIG. Although not shown, the human sensor 63 and the suspicious person warning device 64 are provided with a PLC modem (power line communication adapter) for performing power line communication.

  In this case, human detection information by the human sensor 63 is transmitted to the suspicious person warning device 64 via the power line 65, and it is determined whether or not there is a suspicious person intrusion in the common entrance 61 by the suspicious person warning device 64. . For example, after detecting that a person has entered the apartment house 50 at the common entrance 61, if it is detected that the person has entered the apartment house 50 again with a time difference of about several seconds, the occupants are followed. It is determined that a suspicious person has entered the house. At the time of judging the intrusion of the suspicious person, the suspicious person warning device 64 gives a warning by a lamp, voice or the like to notify the resident or the like of the intrusion of the suspicious person.

  As described above, according to the present embodiment, in the apartment house 50, the breaker ON / OFF is automatically switched by the distribution board 51 for each residence based on the detection information by the human sensor 57 or the like. Room inspection can be performed easily.

  Since the intrusion of the suspicious person is monitored using the human sensor 63 in the common entrance 61, it is possible to generate a deterrent against suspicious acts such as companionship. In addition, when a suspicious act is performed, it can be quickly notified to the surroundings.

  In addition, this invention is not limited to the content of description of the said embodiment, For example, you may implement as follows.

  In addition to the application examples described above, the fire information in the house and the door lock may be confirmed using the detection information of the human sensor. For example, a main plug shut-off device is installed in a room provided with a gas main plug, and detection information such as a human sensor is transmitted to the main plug shut-off device through a power line. In this configuration, when it is determined that the person has left, the gas main plug is automatically tightened by the main plug shut-off device. According to this configuration, even if the fire is forgotten at the gas stand or the like, it can be automatically extinguished. However, since cooking may be performed over a long period of time, taking this into consideration, the gas main stopper may be automatically tightened when a predetermined time has passed after leaving the source of the fire.

  Moreover, an automatic locking device is provided in a room window or the like, and detection information such as a human sensor is transmitted to the automatic locking device through a power line. In this configuration, when it is determined that the person has left, the window is automatically locked by the automatic locking device. In this case, the automatic locking device has a function of confirming a locked state (that is, a door lock state), a function of locking a window, and a warning function using a lamp, sound, or the like. According to this configuration, forgetting to lock the window can be prevented when going out.

  In the human sensor in each of the above embodiments, the detection area may be movable. In this case, it is possible to improve the accuracy of the person's entry / exit determination by appropriately adjusting the detection area. It is also possible to cope with a change in the layout of furniture in the room.

  In each of the embodiments described above, communication between the human sensor and various devices is performed by power line communication. However, this may be changed and another transmission medium such as a LAN may be used. In this configuration, a human sensor 22 is provided integrally with the power outlets 17 to 19, and the human sensor 22 detects the presence or absence of a person using the entrance of the room as a detection area. And it is good to transmit the detection information of the human sensitive sensor 22 to various electric equipments (the lighting fixture 15, the air conditioner 16, etc.) by LAN etc., and to perform automatic control in each electric equipment. In addition to wired communication, wireless communication can be employed as the communication means.

  In addition to housing, this control system can also be applied to public facilities such as schools and hospitals, office buildings, and the like. For example, when applied to a school, it is possible to easily know in which classroom a person has entered or left. In an office building, the usage status of a conference room or the like can be monitored from other rooms. In addition, in an exhibition hall or the like, it is possible to automatically detect that there is a visitor at any venue, and to grasp the attendance situation and the like.
