As shown in FIG. 10A, first, the control unit 38 of the integrated management apparatus 2 refers to the time measured by the time measurement unit 35 and waits until a predetermined time elapses (step S301; No). When the predetermined time has elapsed (step S301; Yes), the control unit 38 uses one of the terminal identifiers such as the temperature sensor terminal 3-1 or the illuminance sensor terminal 4-1 as the destination, and the sensor communication I / F unit 31.

  After storing the sensor information or when a time-out occurs (step S304; Yes), the control unit 38 determines whether or not a sensor information acquisition request has been transmitted to all target sensor terminals (step S306). If transmission of the sensor information acquisition request to all the sensor terminals has not been completed yet (step S306; No), the control unit 38 returns to step S302.

  Thereafter, until a sensor information acquisition request is transmitted to all sensor terminals (step S306; Yes), transmission of the sensor information acquisition request (step S302) → waiting reception of sensor information (step S303 → S304) → storage of sensor information (Step S305) and the like are repeated.

  When the sensor information acquisition request is transmitted to all the sensor terminals (step S306; Yes), the control unit 38 (failure detection unit 80) considers the position information of each sensor terminal stored in the storage unit 33, Based on the difference between the temperature sensor information, the illumination sensor information, and the current control content of the air conditioner control device 5-1, etc., the illumination control device 6-1, etc., the equipment (air conditioner 8-1, etc., lighting fixture) 9-1) is detected (step S307).

  Subsequently, the control unit 38 (request generation unit 81), based on the sensor information of each sensor terminal stored in the storage unit 33 and the failure detection result, the lighting control device 6-1, such as the air conditioner control device 5-1. A device control request to be transmitted to 1 etc. is generated (step S308). More specifically, the control unit 38, based on the position information stored in the storage unit 33, is installed in the vicinity of the facility device (air conditioner 8-1 or the like, lighting fixture 9-1 or the like) in which a failure is detected. Detect equipment. And the control part 38 produces | generates the equipment control request | requirement for performing the environmental control which supplements the equipment apparatus with which the failure was detected with respect to the equipment apparatus which adjoins.

  Subsequently, the control unit 38 causes the control device communication I / F unit 37 to transmit a device control request with the device identifier of the target air conditioner control device 5-1 or the like or the lighting control device 6-1 or the like as a destination ( Step S309). When there are a plurality of target air conditioner control devices 5-1 or the like or lighting control devices 6-1 or the like, device control requests are sequentially transmitted to all of these devices. Then, the control part 38 memorize | stores the control content of illumination control apparatus 6-1 grade | etc., In the memory | storage part 33 etc. (step S310). Thereafter, the control unit 38 returns to step S301.

  Next, the thread 350 executed by the integrated management apparatus 2 will be described with reference to FIG.

  First, the control unit 38 waits until a control change notification is received from the air conditioner control device 5-1 or the lighting control device 6-1 through the control device communication I / F unit 37 (step S351; No). . When the control change notification is received (step S351; Yes), the control unit 38 stores the content of the received control change notification (current control content of the equipment) in the storage unit 33 of the integrated management device 2 (step S352). ). Thereafter, the control unit 38 returns to step S351.

  Next, a failure detection method and a device control request content determination method will be described with reference to FIG.

  For example, assume that the air conditioner 8-1 has failed. In this case, although the air conditioner control device 5-1 controls the air conditioner 8-1, the temperature sensed by the temperature sensor terminal 3-1 is stored in the storage unit 33 of the integrated management device 2. It becomes different from the time series temperature data. For example, the control unit 38 of the integrated management device 2 determines that the air conditioner 8-1 has failed when the difference between them is equal to or greater than a predetermined value. Here, the failure determination is based on the control content by the air conditioner control device 5-1, that is, the current set temperature, the wind direction, etc. stored in the storage unit 33 of the integrated management device 2, the air conditioner on / off, etc. Performed with consideration.

  When it is determined that a failure has occurred, the control unit 38 causes the input / output device 35 to display information related to the facility device in which a failure such as a failure point is detected via the user I / F unit 37 of the integrated management device 2. In addition, the control unit 38 changes the set temperature, the wind direction, and the like of the air conditioner 8-2 in the vicinity of the air conditioner 8-1 so that air conditioning in the area around the air conditioner 8-1 (failed device) can be performed. Generate a control request.

  Further, for example, it is assumed that the lighting fixture 9-2 has failed. In this case, the illuminance acquired by the illuminance sensor terminal 4-2 is different from the time-series illuminance data stored in the storage unit 33 of the integrated management device 2. For example, the control unit 38 of the integrated management device 2 determines that the lighting fixture 9-2 has failed when the difference between them is equal to or greater than a predetermined value. Here, the failure determination takes into account the control content of the lighting control device 6-1, that is, the current brightness and orientation settings stored in the storage unit 34 of the integrated management device 2, the on / off of the lighting fixture, and the like. Done.

  When it is determined that a failure has occurred, the control unit 38 causes the input / output device 35 to display the failure location via the user I / F unit 37 of the integrated management device 2. Moreover, the control part 38 produces | generates the apparatus control request | requirement which changes the brightness, direction, etc. of the lighting fixtures 9-1 and 9-3 so that the lighting of the area around the lighting fixture 9-2 can also be performed. .

  Note that the control of the air conditioner 8-1 and the like, the lighting fixture 9-1, and the like can be artificially performed by the input / output device 35 of the integrated management device 2 in FIG. In that case, it inputs via the user I / F part 36, and controls the air conditioner 8-1 etc., the lighting fixtures 9-1, etc. via the control apparatus communication I / F part 37. The control content (temperature setting, on / off, etc.) is stored in the storage unit 33 of the integrated management device 2 and is referred to when a failure is determined.

  Then, operation | movement of the air-conditioner control apparatus 5-1 grade | etc., Is demonstrated. FIG. 11A shows a thread 400 executed by the air conditioner control device 5-1. FIG. 11B shows a thread 450 executed by the air conditioner control device 5-1.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described.

  The configuration of the facility management system 1 according to this embodiment is the same as the configuration of the facility management system 1 according to the first embodiment shown in FIG. In this embodiment, the same components as those in the first embodiment are given the same reference numerals, and description thereof is omitted.

  In this embodiment, a function of measuring the distance between the terminals is added to the temperature sensor terminals 3-1 to 3-n and the illuminance sensor terminals 4-1 to 4-m according to the first embodiment. .

  The arrangement when the sensor terminals and the control devices for the respective equipments of this embodiment are installed in the room space AR1 is the same as the arrangement example of the first embodiment shown in FIG.

  In this embodiment, it is assumed that there is a one-to-one correspondence between each sensor terminal and each facility device. The sensor terminal paired with the equipment is incorporated in the equipment or is installed near the equipment. In the integrated management apparatus 2, the correspondence relationship between the identifiers of the sensor terminals and the equipment devices is registered in advance. Note that position information is set in advance in at least three sensor terminals.

  FIG. 15 shows an internal configuration of the temperature sensor terminal 3 according to this embodiment. As shown in FIG. 15, the temperature sensor terminal 3-1 is different from the first embodiment in that it further includes a distance measuring unit 61 and an antenna 62. The distance measuring unit 61 has a distance measuring circuit.

  FIG. 16 shows the internal configuration of the illuminance sensor terminal 4-1 according to this embodiment. As shown in FIG. 16, the illuminance sensor terminal 4-1 is different from the first embodiment in that the illuminance sensor terminal 4-1 further includes a distance measuring unit 71 and an antenna 72. The distance measuring unit 71 has a distance measuring circuit.

  The internal configuration of the integrated management device 2, the air conditioner control device 5-1, etc., the lighting control device 6-1, etc. according to this embodiment is shown in FIG. 5 (A), FIG. 5 (B), FIG. This is the same as the internal configuration shown.

  The basic operation of the integrated management apparatus 2 of this embodiment is the same as the operation of the integrated management apparatus 2 of the first embodiment shown in FIG. However, in this embodiment, the integrated management apparatus 2 needs to execute the thread 600 shown in the flowchart of FIG. 17 prior to the operation shown in the flowchart of FIG.

  As shown in FIG. 17, the control unit 38 starts distance measurement via the sensor communication I / F unit 31 with one of the terminal identifiers such as the temperature sensor terminal 3-1 or the illuminance sensor terminal 4-1 as a destination. A request is transmitted (step S601). Each time this step is executed, the destination terminal identifier is sequentially selected from the untransmitted target sensor terminals.

  Subsequently, the control unit 38 determines whether or not a distance measurement result has been received from the target sensor terminal (step S602). If not received (step S602; No), the control unit 38 determines whether or not a timeout has occurred (step S603). If the timeout has not occurred (step S603; No), the control unit 38 returns to step S602. Thereafter, steps S602 → S603 are repeated until the distance measurement result is received (step S602; Yes) or until time-out occurs (step S603; Yes).

  When the distance measurement result is received (step S602; Yes), the control unit 38 stores the received distance measurement result in the storage unit 33 (step S604).

  After storing the distance measurement result or when a time-out occurs (step S603; Yes), the control unit 38 determines whether or not a distance measurement start request has been transmitted to all target sensor terminals (step S605). If transmission of the ranging start request to all the sensor terminals has not been completed yet (step S605; No), the control unit 38 returns to step S601.

  Thereafter, until distance measurement result acquisition requests are transmitted to all sensor terminals (step S605; No), transmission of distance measurement result acquisition requests (step S601) → waiting reception of distance measurement results (step S602 → S603) → measurement The distance result storage (step S604) and the like are repeated.

  When the ranging result acquisition request is transmitted to all the sensor terminals (step S605; Yes), the control unit 38 determines the position of each sensor terminal based on the ranging result of each sensor terminal stored in the storage unit 33. Is estimated (step S606). Subsequently, the control unit 38 stores the estimated position of each sensor terminal in the storage unit 33 (step S607). Thereafter, the control unit 38 ends the thread 600.

  A method for measuring the position of the sensor terminal will be described with reference to FIG.

  It is assumed that the temperature sensor terminals 3-1 to 3-4 are installed in the living room space. The position information of the temperature sensor terminals 3-2 to 3-4 is set in advance in the storage unit 33 of the integrated management device 2. Here, it is assumed that the integrated management device 2 transmits a distance measurement start request to the temperature sensor terminal 3-1. Then, the temperature sensor terminal 3-1 broadcasts distance measurement requests C20-1 to C20-3 to the temperature sensor terminals 3-2 to 3-4 by radio. The temperature sensor terminals 3-2 to 3-4 that have received the distance measurement requests C20-1 to C20-3 wirelessly return distance measurement responses C21-1 to C21-3 to the temperature sensor terminal 3-1. The temperature sensor terminal 3-1 receives a distance measurement response for a certain period of time. The temperature sensor terminal 3-1 transmits each of the temperature sensor terminals 3-2 based on the time from when the ranging requests C20-1 to C20-3 are transmitted until the ranging responses C21-1 to C21-3 are received. Estimate the distances D1 to D3 to ˜3-4.

  The distance measurement responses C21-1 to C21-3 include the identifiers of the returned temperature sensor terminals 3-2 to 3-4. The temperature sensor terminal 3-1 associates the identifiers of the temperature sensor terminals 3-2 to 3-4 with the distances D1 to D3, and transmits them to the integrated management apparatus 2 as a distance measurement result. The integrated management device 2 uses the positions of the temperature sensor terminals 3-2 to 3-4 as the center points of the circles, the distances D1 to D3 as the radii of the circles, and the intersections of the circles as the temperature sensor terminals 3-1. Calculate as position. For example, UWB (Ultra Wide Band) can be adopted as a wireless method used in the distance measurement of this embodiment.

  The basic operations of the temperature sensor terminal 3-1 and the illuminance sensor terminal 4-1 according to this embodiment are the temperature sensor terminal 3-1 and the illuminance sensor terminal 4 of the first embodiment shown in FIGS. This is the same as the operation of -1.

  However, in this embodiment, prior to the operations shown in FIGS. 8 and 9, the thread 700 such as the temperature sensor terminal 3-1 shown in FIG. 19 is executed. As shown in FIG. 19, the temperature sensor terminal 3-1 or the like is used as an example, but the same operation may be performed on the illuminance sensor terminal 4-1 or the like.

  The control unit 16 waits until a ranging start request is received from the integrated management device 2 (step S701; No). When the ranging start request is received (step S701; Yes), the control unit 16 broadcasts a ranging request to another temperature sensor terminal (step S702). Subsequently, the control unit 16 waits until a predetermined time for accepting the distance measurement response has elapsed (step S703; No). When the predetermined time has elapsed (step S703; Yes), the control unit 16 estimates the distance of each sensor terminal from the time from when the ranging request is transmitted until the ranging response is received (step S704). Subsequently, the control unit 16 transmits the distance measurement result to the integrated management device 2 (step S705). Thereafter, the control unit 16 ends the thread.

  As described in detail above, according to the facility management system 1 of this embodiment, in addition to being able to detect failures of air conditioners and lighting fixtures and automatically complementing these devices, input of installation positions to each sensor terminal Work can be omitted. As a result, air conditioning and lighting control can be performed without impairing the comfort of the occupants, and the installation work of each sensor terminal can be facilitated.

  In the above embodiment, the program to be executed is a computer-readable recording medium such as a flexible disk, a CD-ROM (Compact Disc Read-Only Memory), a DVD (Digital Versatile Disc), and an MO (Magneto-Optical Disc). A system that executes the above-described thread may be configured by storing and distributing the program in a medium and installing the program.

  Further, the program may be stored in a disk device or the like included in a predetermined server device on a communication network such as the Internet, and may be downloaded, for example, superimposed on a carrier wave.

  In addition, when the above functions are realized by sharing an OS (Operating System), or when the functions are realized by cooperation between the OS and an application, only the part other than the OS may be stored in a medium and distributed. You may also download it.
