JP 2005-11222 A

  In the system disclosed in Patent Literature 1, when it is determined that a resident has an abnormality or has forgotten to lock each residential household, the information is notified to a predetermined communication partner and displayed.

  However, some residents may feel uncomfortable that such information is displayed to the communication partner from the viewpoint of privacy. In particular, even if the resident is in a resting state due to a nap, reading, etc., if there is no movement for a predetermined time, it is judged that an abnormality has occurred, and it is not intentionally locked for going out for a short time. Even in such a case, it may be determined that the user has forgotten to lock the door and be notified. There is a possibility that a resident who values privacy will want to avoid being displayed to the other party even in such a case.

  The main object of the present invention is to provide a system that displays information that is necessary to grasp security and energy use while respecting the privacy of residents.

  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.

  The building management information display system of the present invention is provided in each of a plurality of spaces in a building (house 10), and information acquisition means (sensors K1 to K4, H1 to H4, F1 to F4) for acquiring management information for each space. , Monitors D1 to D4, G3, W3), building-side communication means (communication unit 43) that is provided in the building and transmits management information for each space acquired by the information acquisition means, and based on a request, Display control means (in-vehicle device 52) for receiving the management information by performing wireless communication with the building-side communication means and displaying the received management information on a display device (display device 55). Further, when the management information is displayed by the display control means, information selection means (home server 41, in-vehicle device 52) for selecting management information permitted to be displayed is provided according to the user who issued the request.

  This system transmits management information related to building security, energy usage, and the like from the building side at the request of the user, and displays it on the display device. In this case, the management information displayed is only the management information permitted according to the requesting user. Therefore, management information unnecessary for the requesting user is not displayed, and it is possible to appropriately protect the resident's privacy, while management information determined to be grasped by the user is displayed without excess or deficiency. Therefore, security and energy use can be managed accurately.

  The said system may recognize the said user by the said identification information transmitted from the portable communication apparatus (electronic key 61) which is carried by the user and memorize | stores identification information specific to a user. In this case, it is preferable to store in the storage means (memory 42, memory 54) which management information among the plurality of management information is permitted to be displayed in association with the identification information. Then, the information selection means selects only the management information associated with the identification information of the user who issued the request.

  For example, one user displays only management information related to security and specializes in security management, while another user displays only management information related to energy usage and specializes in management related to energy use. In some cases, the management information displayed by the user may be limited. In the above configuration, since only management information permitted for each user is displayed, it is possible to sufficiently meet the desire to limit the management information displayed by the user as described above.

  Further, it is preferable to store in the storage means (memory 42, memory 54) which management information of the plurality of spaces is permitted to be displayed in association with the identification information. In this case, the information selection means selects only the management information of the space associated with the identification information of the user who issued the request.

  For example, there is a case where it is desired to change a space (room or the like) for displaying management information according to the user from the viewpoint of privacy protection. In the above configuration, since only the management information of the space permitted for each user is displayed, it is possible to sufficiently cope with the desire to limit the display target space by the user as described above.

  In the system using the portable communication device, user identification is performed by transmitting and receiving identification information for each user through communication. Therefore, since the user does not need to input identification information by himself / herself and is not troubled, the convenience is high.

  It is preferable that the display control means and the display device are mounted on a vehicle (vehicle 50). With this configuration, there is an advantage that the security state of the building can be confirmed by the vehicle.

  In addition, when the determination unit (in-vehicle device 52) determines that the user goes out by the vehicle and the determination unit determines that the user has gone out, the management information is transmitted to the building-side communication unit. It is preferable to further comprise means for outputting the request (on-vehicle device 52). Furthermore, the determination means may determine that the user has gone out when the engine of the vehicle is started.

  For example, if the engine of the vehicle is started, it is considered that there is a high probability of going out by the vehicle. Therefore, it is preferable that the determination means determine that the vehicle is going out when the engine is started. However, when the user inputs a password on the vehicle side and the authentication is performed, when the door of the vehicle is unlocked or opened, or when the user is seated in the driver's seat of the vehicle, etc. May be. In the above configuration, since management information is displayed on the display device when it is determined that the user has gone out, forgetting to lock or forgetting to tighten the water faucet can be confirmed before the vehicle leaves the building. Energy management can be performed reliably.

  Moreover, it is preferable to further comprise means (home server 41, in-vehicle device 52) for outputting the request for transmitting management information to the building-side communication means at a predetermined time period. With this configuration, a management information transmission request to the building-side communication means is automatically output, and the user can reliably check the management information periodically.

  It is preferable that the management information includes information related to the locked / unlocked state of windows or doors provided in the building and information related to building fires, gas leaks, or intruders in the building. Thereby, building security management can be performed. Or it is also suitable to include the information regarding the usage-amount of gas, electricity, or water. Thereby, energy use management of a building can be performed.

  When the abnormal state is grasped based on the management information, it is preferable that the display control unit displays information for notifying the abnormal state on the display device. For example, if notification is made when an abnormal state such as forgetting to lock or fire or an abnormal state such as forgetting to close a water tap is detected, the user can respond quickly.

  Hereinafter, an embodiment in which a building management information display system of the present invention is embodied will be described with reference to the drawings. First, a schematic configuration of the building management information display system will be described with reference to FIG.

  In the two-story house 10, rooms 11 and 12, a kitchen 13, and an entrance 14 are provided as indoor spaces (in FIG. 1, a part of the space provided in the house 10 is representatively represented. Other spaces such as toilets, bathrooms, corridors are omitted).

  In each space 11-14, locking / unlocking sensors K1, K2, K3, K4, human sensors H1, H2, H3, H4, fire sensors F1, F2, F3, F4, and power usage monitor D1, D2, D3, and D4 are provided. The locking / unlocking sensors K1 to K4 are provided in the windows 21, 22 and 23 in the rooms 11 and 12 and the kitchen 13, respectively, and are provided in the entrance door 24 in the entrance 14, and the windows 21 to 23 and the entrance door 24 are locked. / Detect unlocked state. Each of the human sensors H1 to H4 detects whether or not a person is present in each of the spaces 11 to 14 based on the presence or absence of infrared rays emitted by the person. Each fire sensor F1 to F4 detects whether or not a fire has occurred in each of the spaces 11 to 14 based on the amount of change in smoke or heat. Each power usage monitor D1-D4 monitors the power usage used by the housing equipment (lighting fixture, television, audio, refrigerator, microwave oven, etc.) provided in each space 11-14. Further, the kitchen 13 is further provided with a gas usage monitor G3 and a water usage monitor W3, and monitors the gas usage and the water usage used in the kitchen 13, respectively. Note that sensors and monitors are provided as appropriate in other spaces omitted in FIG.

  The sensors K1 to K4, H1 to H4, F1 to F4, and the monitors D1 to D4, G3 and W3 are connected to the home server 41 via network lines 31, 32, 33 and 34. The home server 41 includes a CPU, a memory 42, a communication unit 43, and the like. In the home server 41, the detection results of the sensors K1 to K4, H1 to H4, and F1 to F4, and the monitors D1 to D4, G3, and W3. The monitoring result is stored in the memory 42. Moreover, the home server 41 grasps | ascertains the abnormal state in the house at the time of going out of a user based on these detection results or a monitor result. For example, when it is detected by the unlocking sensors K1 to K4 that the windows 21 to 23 and the entrance door 24 are not in a locked state, it is grasped as an abnormal state. Similarly, when a person is detected by the human sensors H1 to H4, or when a fire is detected by the fire sensors F1 to F4, the power consumption monitors D1 to D4, the gas usage monitor G3, and the water usage When the usage amount exceeding the predetermined value is monitored by the monitor W3, it is grasped as an abnormal state. In addition, even when users other than the user who goes out exist in a house, it will be detected by human sensor H1-H4. However, before the user who goes out, the number of people detected by the human sensors H1 to H4 is grasped in advance, so that it is grasped whether or not it is an abnormal state by the increase / decrease. That is, if the number of people increases or decreases after the locking / unlocking device 25 is normally locked / unlocked by the electronic key 61 described later, it is understood that the increase / decrease is normal. On the other hand, if the number of people increases or decreases even though the locking / unlocking device 25 is not normally locked / unlocked, it is recognized as an abnormal state.

  The home server 41 communicates with the sensors K1 to K4, H1 to H4, F1 to F4, and the monitors D1 to D4, G3, and W3 through the communication unit 43. Communication is also performed with the locking / unlocking device 25 provided at the entrance door 24. Furthermore, the communication part 43 communicates with the vehicle-mounted apparatus 52 with which the vehicle 50 was equipped by radio | wireless. The communication unit 43 is also connected to the Internet 35 and can exchange information with the outside.

  The locking / unlocking device 25 includes a wireless communication unit 26 and a memory 27. The wireless communication unit 26 periodically transmits a request signal (locking / unlocking request signal). This request signal is received by the electronic key 61, and ID information is transmitted from the electronic key 61 in response thereto. Here, the memory 27 stores ID information of an electronic key 61 to be described later, and the locking / unlocking device 25 authenticates whether or not the ID information stored in the memory 27 matches the received ID information. Then, when it authenticates, the front door 24 is automatically locked / unlocked.

  The electronic key 61 includes a wireless communication unit 62. For example, an area having a radius of about 3 meters is set as a communication range (transmission / reception range), and wireless communication is possible between the locking / unlocking device 25 and the in-vehicle device 52. The electronic key 61 is provided with a memory 63, and the memory 63 stores individual ID information (identification information) that is different for each owner (user). This ID information is information that enables at least users who are authenticated by the present system and a plurality of users to be authenticated (for example, family members living together) to be individually identified.

  The in-vehicle device 52 includes a wireless communication unit 53 and a memory 54. The wireless communication unit 53 can communicate with devices inside and outside the vehicle 50, can perform wireless communication with the communication unit 43, and can be connected to the Internet 35. The wireless communication unit 53 also periodically transmits a request signal (locking / unlocking request signal) while the vehicle 50 is not being used. When this request signal is received by the electronic key 61, ID information is transmitted from the electronic key 61 in response thereto. Here, the memory 54 stores the ID information of the electronic key 61, and the in-vehicle device 52 authenticates whether or not the ID information stored in the memory 54 and the received ID information match, and authenticates that they match. In this case, the locking / unlocking device 51 of the vehicle 50 is automatically unlocked.

  In the building management information display system having the above configuration, when the engine start of the vehicle 50 is detected by the vehicle-mounted device 52, the vehicle-mounted device 52 transmits a request signal for information stored in the home server 41 to the communication unit 43. When the request signal is input to the home server 41, the home server 41 detects the detection results of the sensors K1 to K4, H1 to H4, F1 to F4, and the monitors D1 to D4 based on the input information. Information on the monitoring results of G3 and W3 is transmitted to the in-vehicle device 52. When the in-vehicle device 52 receives these pieces of information, the display device 55 connected to the in-vehicle device 52 displays these detection results and monitor results (hereinafter collectively referred to as “management information”). The display device 55 may be provided with a setting input unit including a large number of input buttons and the like, and may be displayed by appropriately selecting from displayable management information by a user input operation. In this case, the input operation is facilitated by enabling input on the display unit of the display device 55.

  In the building management information display system of the present embodiment, the process of displaying the management information is started when the engine of the vehicle 50 is started. The reason why the start trigger of this display process is “engine start” is that this process is effective when going out by the vehicle 50, and it is considered that there is a high probability of going out by the vehicle 50 when the engine is started. (For example, “engine start” is more likely to go out than “door unlocking” or “sitting in the driver's seat”).

  Next, the procedure of the management information display process will be described based on the flowchart of FIG.

  In FIG. 2, it is determined in step S11 whether or not the engine of the vehicle 50 has been started. In the vehicle 50, an in-vehicle device 52 is connected to an ECU (electronic control unit) that executes control of a vehicle engine or the like, and engine start is determined based on a start signal output from the ECU.

  If it is determined that the engine has been started as a start trigger for the management information display process (YES in step S11), ID information is acquired from the electronic key 61 that has started the engine in step S12. And it transfers to step S13 and implements user authentication based on the received ID information. And if it is authentication NG at step S13 (NO at step S13), this process is terminated. On the other hand, if the authentication is OK (YES in step S13), the process proceeds to step S14. In step S14, display processing is executed based on the ID information.

  Once the engine is started, NO is determined in step S11, the process proceeds to step S15, and it is determined whether or not the engine of the vehicle 50 is in operation. If the engine is operating (YES in step S15), the display process in step S14 is executed again. In the present embodiment, once the engine is started, the display process of step S14 is executed at a cycle of a predetermined time (for example, several tens of minutes or several hours). Thereby, until it is determined that the engine is stopped (until NO is determined in step S15), the display process of step S14 is repeated at a predetermined time period.

  When the vehicle is not used, the engine is not started and the engine is not operating. Therefore, NO is obtained in both steps S11 and S15, and the present process is terminated without executing the display process in step S14.

  Details of the display processing in step S14 will be described. In this process, first, the in-vehicle device 52 transmits a management information transmission request signal to the communication unit 43 together with the ID information of the electronic key 61. The ID information and transmission request signal received by the communication unit 43 are received by the communication unit 43 of the home server 41. The home server 41 authenticates whether or not the received ID information matches the ID information stored in the memory 42, and transmits management information to the in-vehicle device 52 when it is authenticated. The type of management information transmitted to the in-vehicle device 52 is different for each received ID information, and the type of management information that can be displayed in the memory 42 of the home server 41 in association with each ID information. Is remembered. A method for selecting the type of management information for each ID information will be described below. Here, the case where three users U1, U2, and U3 are assumed is illustrated, and for each ID information of each of these users U1 to U3, (1) which management information is to be displayed among a plurality of management information is selected. And (2) the case of selecting which management information of a plurality of spaces to display will be described.

  (1) (a) of FIG. 3 shows the detection results of the sensors K1 to K4, H1 to H4, and F1 to F4, and the monitors D1 to D4, G3, and W3 for each ID information of the users U1 to U3. FIG. 6 is a correspondence diagram showing an example of a correspondence relationship indicating which display is permitted for a monitor result, where “◯” indicates display permission and “×” indicates display prohibition. The association information (association data) is stored in the memory 42 of the home server 41.

  According to (a) of FIG. 3, display is permitted in common for any user with respect to the detection results of the locking / unlocking sensors K1 to K4, the human sensors H1 to H4, and the fire sensors F1 to F4. Further, only the users U1 and U2 are allowed to display the monitor results of the power consumption monitors D1 to D4, and only the user U1 is allowed to display the monitor results of the other monitors G3 and W3. That is, the display of the monitor results of the monitors D1 to D4, G3, and W3 is limited for each user as illustrated.

  (2) FIG. 3B shows, for each ID information of each of the users U1 to U3, which display permission is permitted for the detection results of the locking / unlocking sensors K1 to K4 and the human sensors H1 to H4 in each space in the house. It is a correspondence diagram showing an example of the correspondence relationship of whether or not, in the figure, ○ indicates display permission, × indicates display prohibition. The association information (association data) is stored in the memory 42 of the home server 41.

  According to FIG. 3 (b), the display of management information (detection results of sensors K1 to K4 and H1 to H4) of all spaces in the house is permitted for the user U1, whereas the room for the user U2 is allowed. 12 management information (detection results of sensors K2 and H2) is prohibited, and display of management information of room 11 (detection results of sensors K1 and H1) is prohibited for user U3. In other words, the display of information for each space is limited and the display is limited for each user.

  The home server 41 refers to the type of the management information stored in the memory 42 and selects the type of management information corresponding to the input ID information. Then, the selected management information is transmitted to the in-vehicle device 52 via the communication unit 43.

  The management information received by the in-vehicle device 52 is displayed on the display device 55. The display device 55 can display detection results and monitor results for each space in the house. It is also possible to arbitrarily select and display only predetermined detection results and monitor results, or only information related to a predetermined space, by a user input operation.

  Further, when the home server 41 grasps an abnormal state in the house, the home server 41 transmits information indicating the abnormal state to the in-vehicle device 52. The transmission timing may be the same timing as the information display process (step S14 in FIG. 2) repeated at a predetermined time period, or may be a different timing from this process. In addition, the transmission of information indicating an abnormal state may correspond to the type of management information that can be displayed. For example, when the usage amount exceeding a predetermined value is monitored by the gas usage amount monitor G3, if the ID information of the user U1 or U2 is input, information indicating the abnormal state is transmitted to the in-vehicle device 52 (user U3 If the ID information is input, it is not transmitted.) When information indicating an abnormal state is received by the in-vehicle device 52, an alarm (blinking display, voice display, etc.) is generated on the display device 55 and notified to the user.

  When the management information selected by the home server 41 is transmitted, or when information indicating an abnormal state is transmitted, if the vehicle 50 is within the communication range of the communication unit 43, the transmitted information is stored in the in-vehicle device 52. Directly received by the wireless communication unit 53. On the other hand, if the vehicle 50 is outside the communication range of the communication unit 43, the transmitted information is received by the wireless communication unit 53 of the in-vehicle device 52 via the Internet 35. Thereby, even if the vehicle 50 is in a remote place from the house 10, information is reliably transmitted.

  With the above configuration, the following advantageous effects can be obtained.

  The electronic key 61 stores only ID information, and does not store house management information, a personal identification number, or the like transmitted from the home server 41. The ID information stored in the electronic key 61 is used only for selecting management information, and is not used for unlocking the locking / unlocking device 25 of the house 10, for example. Even if left unattended, there is a low possibility of misuse and it is safe.

  When the home server 41 receives the ID information and the transmission request signal transmitted from the in-vehicle device 52, the home server 41 selects the type of management information corresponding to the ID information from the memory 42, and transmits the selected management information to the in-vehicle device 52. . Therefore, management information unnecessary for the user having the ID information is not displayed, and the privacy of other residents can be appropriately protected. On the other hand, management information determined to be necessary for the user is displayed without excess or deficiency, and security and energy usage can be managed accurately.

  In the memory 42, a displayable space (such as a room) is also stored in association with each ID information, so that the display space can be changed according to the user.

  Since the display process is started when the user starts the engine of the vehicle 50, if the probability of going out with the vehicle 50 is high, forgetting to lock before the vehicle 50 leaves the house 10 or the water faucet You can check if you forgot to tighten.

  Note that the present invention is not limited to the embodiment described above, and can be implemented, for example, in the form shown as another example below.

  In the above embodiment, the present system is applied to a detached house, but may be applied to an apartment house such as an apartment. Or you may apply to the building provided with several rental offices. In this case, each space in the above embodiment corresponds to each residential household in the apartment house, each rental office in the building, and the like.

  The fire sensors F1 to F4 in the above embodiment may be replaced with gas leak sensors. Or you may provide a gas leak sensor with the fire sensors F1-F4.

  You may replace each sensor K1-K4, H1-H4, F1-F4 in the said embodiment with a surveillance camera. The monitoring camera can detect the locked / unlocked state, the presence of a person, and the occurrence of a fire. In this case, some of the sensors K1 to K4, H1 to H4, and F1 to F4 may be replaced with monitoring cameras. Or it is also possible to provide a monitoring camera together with the sensors K1 to K4, H1 to H4, and F1 to F4.

  In the above-described embodiment, the authentication information ID stored in the electronic key 61 is authenticated by the in-vehicle device 52 when the engine is started, as a start trigger for the management information display process. However, instead of this, the start trigger may be the authentication of the password entered by the user from the input device (or the display device 55). Alternatively, both ID information authentication and password authentication may be used as start triggers.

  Moreover, it is good also as a start trigger of management information display processing when the door unlocking by the locking / unlocking device 51 of the vehicle 50 or the seating in the driver's seat is detected. Note that the driver can sit in the driver's seat using a weight sensor, a human sensor, or the like. Or it is also possible to use the start trigger when the door is unlocked or seated in the driver's seat and the engine is started or the password is authenticated.

  In the above embodiment, the type of management information that can be displayed in association with each ID information is stored in the memory 42 of the home server 41, but this information may be stored in the memory 54 of the in-vehicle device 52. In this case, only the type of management information associated with the authenticated ID information is requested to be transmitted to the home server 41, and the type of management information transmitted in response to this transmission request is displayed on the display device 55. can do. Alternatively, all the management information may be collectively transmitted from the home server 41 to the in-vehicle device 52, and what can be displayed on the in-vehicle device 52 is selected and then displayed on the display device 55.

  In the above embodiment, after the engine of the vehicle 50 is started, the in-vehicle device 52 transmits a management information transmission request signal at a predetermined time period, and the management information is transmitted from the home server 41 accordingly. However, the home server 41 may automatically transmit the management information to the in-vehicle device 52 at a predetermined time period without transmitting the transmission request signal from the in-vehicle device 52.
