Referring to FIG. 1, a human flow analysis system according to an embodiment 10 of the present invention is installed in a building such as a company, a warehouse, a school, an educational facility, a nursing home, a hospital, etc. It consists of a human flow analyzer 12, a private branch exchange (PBX) 14, and a facility management system 16. The tenth embodiment is embodied in a human flow analysis system, but it goes without saying that the basic technical idea of the present invention is applicable not only to human flow but also to physical distribution. In such a case, in the present application, not only physical distribution but also human flow is referred to as “target physical distribution”.

  In this embodiment, the private branch exchange 14 is connected to a station line 18 of a public telephone exchange network, and generally includes a plurality of extension telephones 20 and a radio base station (CS) 22. The office line 18 may also accommodate a plurality of lines. The radio base station 22 is a base station device that can be connected by radio 26 to a wireless extension mobile terminal 24 such as PHS, for example, within the radio wave connectable range. The private branch exchange 12 is a telephone exchange that sets up a call connection between the extension terminal devices such as the extension telephone 20 and the wireless mobile terminal 24 and between them and the office line 18 and enables a call between them. is there. Of course, these extension telephones 20 and mobile terminals 24 are assigned identification codes, preferably extension telephone numbers, which uniquely identify them.

  In FIG. 1, only a specific number of the office lines 18, telephones 20, base stations 22, and mobile terminals 24 are shown in order to avoid complication of the figure, but a number larger than that shown may be provided. Needless to say.

  The human flow analyzer 12 and the facility management system 16 are connected to the private branch exchange 14 as shown in the figure by a system bus 28 in this embodiment. The bus 28 constitutes an information transfer path for transferring information such as terminal position information 102 (FIG. 5) and control information 104 (FIG. 6) described later between these devices 12, 14 and 16.

  The human flow analysis device 12 is an information processing device that acquires the terminal position information 102 from the bus 28, analyzes this, and generates control information 104 on the bus 28 according to control conditions corresponding to the terminal position information 102. This will be described in detail later with reference to FIG.

  The facility management system 16 is a management device that manages various devices 30 in a facility such as a building where the system 10 is installed. In the present embodiment, the various utilization devices 30 include an air conditioner 32, a lighting device 34, an air purifier, an elevator such as an elevator or an escalator, and their power supply facilities. These devices 30 can be operated locally, such as the power supply and operating conditions, even in the respective devices themselves. However, in this embodiment, the devices 30 are connected to the facility management system 16 by the connection line 36 and are also concentrated in the management system 16. It is configured to be controllable. What is characteristic in the present embodiment is that the facility management system 16 is configured to be able to control the operation state of the utilization device 30 in response to the control information 104 received from the bus 28.

  Referring to FIG. 2, the human flow analysis device 12 includes a position information acquisition unit 40, a position information analysis unit 42, and a position information storage unit 44, and further includes a control unit 46 that controls these in an integrated manner. The location information acquisition unit 40 is a functional unit that is connected to the system bus 28, acquires data from the private branch exchange 14 under the control of the control unit 46, particularly the terminal location information 102, and stores this in the location information storage unit 44. is there. The location information storage unit 44 includes an area management table as illustrated in FIG. 4 and stores the terminal location information 102 acquired by the location information acquisition unit 40 in a corresponding field of this table. This will be described in detail later. In this embodiment, the terminal location information 102 includes the area designation field 108, but in addition to this, a call log for the mobile terminal 24 may be included.

  Although not shown, the position information acquisition unit 40 may be provided inside the private branch exchange 14. In that case, the location information acquisition unit of the private branch exchange 14 is configured to assemble the terminal location information 102 (FIG. 5) with reference to the CS correspondence memory 38 and store this in the location information storage unit 44.

  In connection with the human flow analyzing apparatus 12 configured as described above, the private branch exchange 14 is provided with a base station (CS) correspondence memory 38, in which a base station correspondence table as illustrated in FIG. 3 is stored. ing. In this embodiment, the telephone 1 and the base station 1 are disposed in one of the physical areas of the facility, that is, the facility area 48, for example, the area 1, and the telephone 2 and the base station 2 are disposed in the other facility area 2. It is installed. These areas 1 and 2 are in-facility areas such as conference rooms, office rooms or a section thereof, store booths or a section thereof, warehouse rooms or a section thereof, and are within the radio wave coverage area of the base station 22, that is, services. It may be an area. The base station correspondence table 38 is a correspondence table that defines or stores the correspondence between the area 48 and the base station 22.

  Under the control of the control unit 46, the location information analysis unit 42 refers to the data stored in the location information storage unit 44, derives control information 104 that meets a predetermined control condition, and transmits this to the facility management system 16 from the bus 28. Processing system. The facility management system 16 uses the control information 104 as described above to control the utilization device 30.

  The exchange of data and control signals with the position information acquisition unit 40 and the position information analysis unit 42 with respect to the position information storage unit 44 is indicated by corresponding connection lines 50 and 52, respectively. The position information acquisition unit 40, the position information analysis unit 42, and the position information storage unit 44 are controlled by the control unit 46, and the control is symbolically illustrated by the connection line 54.

  Referring to FIG. 4 again, the area management table of the location information storage unit 44 stores, for each of the facility areas 48 in the facility, data indicating the existence status of the mobile terminal 24 in the facility area 48 in time series T1, T2, T3. ... includes a field 60 for real-time storage. The time series T1, T2, T3... May be, for example, at regular time intervals. The area management table further defines a control condition field 62 for defining or recording the control conditions of the used devices 30 in the facility area 48, and the operating state of the used devices 30 to be controlled, for example, the power supply It has a control information field 64 for defining or recording on / off, operation state settings, and the like.

  FIG. 4 shows an example in which the area 1 is an office room or one section thereof, and the area 2 is a meeting room or one section thereof. When the mobile terminal 24 no longer exists in the area 1, that is, when the control condition 62 that the number of terminals becomes a predetermined threshold, “0” in this example, is satisfied, the lighting in the area, that is, the office room Control information 64 for shutting down the power supply of the device 34 is set. As another example of the control condition 62, “the number of terminals changes to other than 0” is defined, and the corresponding control information 64 is defined as “turning on lighting equipment” and / or “turning on air conditioning equipment”. Also good.

  For area 2, when the number of mobile terminals 24 in the area increases to a predetermined threshold number, in this example “three or more”, the temperature setting value of the air conditioner 32 in that area, that is, the conference room is changed from the current setting value to a predetermined width. In this example, the control information 64 is set to lower twice by Celsius. The amount of decrease in the temperature set value may not be 2 degrees, but may be another value. Of course, it may be a value including a decimal point. Further, such a fixed value may not be used, and may be a variable value corresponding to the number of mobile terminals 24 included in the area 48, for example. For example, the amount of reduction may be increased when the number of such vehicles increases, and the amount of reduction may be increased accordingly when the number of people in the region 48 is exceeded, that is, when the number exceeds the capacity.

  Therefore, in this facility, for example, a company, its members, that is, employees, generally own one mobile terminal 24, and move around the facility while carrying it. The technical concept of the human flow analysis in the present embodiment relies on such behaviors of the members. In the operating state, the CS correspondence memory 38 of the private branch exchange 14 stores that the base station 1 is disposed in the area 1 and the base station 2 is disposed in the area 2 as illustrated in FIG. ing. In the CS correspondence memory 38, when the base station 22 is installed or moved, for example, a maintenance staff may set the correspondence relationship between the base station 22 and the region 48 in the memory 38.

  In general, a private branch exchange always knows a radio wave service area in which a slave unit exists, that is, a service area, mainly for incoming connection to a wireless slave unit. This is a normal terminal location specifying operation in the private branch exchange 14. Therefore, the control unit 58 of the private branch exchange 14 can always grasp which of the mobile terminals 24 exists in which area 48 for call connection setting to the mobile terminal 24. In this embodiment, by using the terminal position information 102 that grasps the area 48 where the mobile terminal 24 is located, the behavior data of the employee in the facility is obtained, and this is analyzed by the human flow analysis device 12 to control information. By generating 104, the facility management system 16 can use the latter for controlling the utilization device 30.

  In this embodiment, the correspondence between the mobile terminal 24 and the area 48 is output from the private branch exchange 14 to the bus 28 in the form of terminal location information 102 in a format as shown in FIG. . The terminal location information 102 includes a terminal designation field 106 and an area designation field 108 as shown in the figure. This transfer may be such that the terminal location information 102 is output from the private branch exchange 14 and is performed in response to the request of the location information acquisition unit 40 under the control of the control unit 46 of the human flow analyzer 12. You may comprise. The transfer timing may be regular at a predetermined time interval or may be a point in time according to a request from the human flow analysis device 12.

  Based on the terminal position information 102 transferred from the private branch exchange 14 as described above, the position information analysis unit 42 grasps the area 48 where the mobile terminal 24 is currently located. More specifically, when the location information acquisition unit 40 acquires the terminal location information 102, the location information storage unit 44 identifies the region 48 in which the mobile terminal 24 recorded in the mobile terminal designation field 106 is located. The identification information of the mobile terminal 24, that is, the extension telephone number in this example, is written in the field 48 of the corresponding area 48 of the area management table in time series. In the example shown in FIG. 4, mobile terminals 1, 2, and 3 exist in area 1 and mobile terminal 4 exists in area 2 at time T <b> 1. At the next time T2, there is no change in the mobile terminal 24 existing in the area 1, but the mobile terminal 5 is added to the area 2. Further, at time T3, for region 1, the mobile terminals 2 and 3 move to region 2 and only the mobile terminal 1 remains, and the mobile terminals 6 and 7 are newly added to region 2. At time T4, the mobile terminal 1 has left the area 1 and the mobile terminal 24 no longer exists in the area 1.

  The position information analysis unit 42 always refers to the area management table 44 and monitors whether each area 48 satisfies the control condition 62. For example, in the case of the area 1, the control condition 62 defines “change to the number of terminals“ 0 ””, and the corresponding control information 64 defines “illumination equipment power-off”. Therefore, in this example, the location information analysis unit 42 has changed to the number of terminals “0” at time T 4 for the region 1, and therefore assembles control information 104 corresponding thereto and outputs this to the bus 28.

  Similarly, in the case of the area 2, the control condition 62 is defined as “change to the number of terminals“ increase to 3 or more ””, and the corresponding control information 64 includes “the temperature setting value of the air conditioner from the current setting value”. ”Turn down twice”. Therefore, the position information analysis unit 42 assembles the corresponding control information 104 and outputs it to the bus 28 because the number of terminals has changed to “increase to 3 or more” for the region 2 at time T3.

  By the way, the control information 104 includes a device designation field 110 and two operation designation fields 112 and 114 in this example. The device designation field 110 is a field for recording information for identifying any of the used devices 30, for example, the air conditioning device 32 or the lighting device 34. In the present embodiment, the operation designation fields 1 and 112 are fields that specify the power on / off of the device. In the present embodiment, the other operation designation fields 2 and 114 are the setting state of the device, for example, the illuminance variable illumination device. In the field, the setting value of the illuminance, or the setting value of the temperature, humidity, ventilation, etc. of the air conditioner is defined. Here, the set value may be an absolute value such as 25 ° C. or a relative value such as a difference from the current room temperature or the outside air temperature. In the example shown in FIG. 4, two operation designation fields are provided, but there may be one, or three or more operation designation fields.

  Now, the control information 104 output from the human flow analyzer 12 to the bus 28 is taken into the facility management system 16, and the facility management system 16 decodes the control information 104 and records the use device recorded in the device designation field 110. 30 is operated according to the operation recorded in the operation designation fields 112 and 114.

  In the example shown in FIG. 4, the lighting device 34 is designated in the device designation field 110 of the control information 104 and the operation designation field 112 is designated as “power off” for the area 1, in this example, the office. Therefore, the facility management system 16 controls the lighting device 34 corresponding to the area 1 and shuts off the power supply. That is, since all of the employees have left the office at time T4, the power to the lighting device 34 is cut off at this point.

  On the other hand, for the area 2, in this example, the conference room, the air conditioner 32 is designated in the equipment designation field 110 of the control information 104, and the temperature designation value is designated as “lower the temperature set value twice from the current set value”. Has been. Therefore, the facility management system 16 controls the air conditioner 32 corresponding to the area 2 and lowers its temperature setting value twice. That is, at time T3, the number of mobile terminals 24 in the conference room increased by 3 from the previous time T2, that is, six people gathered in the conference room, and at this point, the temperature setting value of the air conditioner 32 decreased twice. become. In the present application, such presence / absence and density of the mobile terminals 24 in the region 48 are collectively referred to as a “distributed state”.

  In this embodiment, between the extension terminal 24 and the base station 22 and between the base station 22 and the private branch exchange 14, in addition to information necessary for normal call connection operation, special information, for example, information necessary for human flow analysis Will not be given or received. In addition, collection, management, and analysis of human flow data are configured to be performed by the private branch exchange 14 and the human flow analysis unit 12. Therefore, no extra load for human flow analysis is applied to call connection and radio control to the radio mobile terminal 24, and call connection control is performed with the conventional efficiency.

  Thus, when introducing the human flow analysis system, it is not necessary to make a major change to the existing telephone exchange system, and it is sufficient to add a connection to the human flow analysis device and its facility management system.

  As described above, according to the present embodiment, it is possible to control the equipment used by the facility management system 16 in real time according to the behavior of each employee in the facility. Specifically, if there are many people who flow into a certain area 48 in the facility, the set temperature of the air conditioner 32 in that area 48 can be lowered, or the operation mode of the air cleaner can be strengthened.

  By collecting such human flow data for a certain period, such as several months, statistical data on the human flow in the facility can be obtained. The set value of the facility management system 16 can be set using such statistical data. It may be updated. Specifically, using the statistical data, it is possible to set the air-conditioning setting to be automatically switched for each region 48 in the facility in accordance with the temporal change in the density of employees. In addition, using the statistical data, it is possible to optimize the setting of the automatic turn-off time of a lighting device that is automatically turned on by a detector such as a human sensor.

  Human flow statistics data can also be used to estimate the frequency of use of hand-washing rooms in the facility. In such a case, the amount of flushing water in the urinal can be optimized by human flow analysis, and a water saving effect can be expected in addition to power saving. Thus, the facility as a whole can be expected to have effects such as power saving, resource saving, and improvement of comfort.

  Furthermore, such human flow analysis data can be used not only for the optimization of the set values in the existing system under normal operation as described above, but also when a facility is newly established or renovated. Specifically, it can contribute to the examination of the optimal arrangement of necessary equipment and facilities according to the analyzed behavior pattern of the employee. It is also possible to analyze the density of employees in the facility and derive the optimal arrangement of the radio wave service area of the base station 22.

  When the call log is used for human flow analysis in addition to the location information 102 of the mobile terminal 24, it is possible to more appropriately deploy the necessary equipment and facilities, for example, to optimize the layout of facilities such as conference rooms and warehouses. More advanced.

  The present invention is not limited only to the above-described embodiments. In other words, the present invention covers the scope of application even if a part or all of the above-described embodiments are arbitrarily combined or partially extracted.

  Although the invention has been described with reference to particular embodiments, the invention is not limited to these embodiments. It should be recognized that those skilled in the art can change or modify these embodiments without departing from the scope and concept of the present invention.
