Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The embodiment of the present invention will be described by taking an example in which the present invention is applied to a medical facility, but the present invention may be applied to a nursing facility, a factory, and other facilities.
Fig. 1 is a block diagram showing a system (calling system) 10 of the present embodiment. The system 10 includes a fixed machine (fixed device) 12, a calling terminal (mobile machine) (with tag) 14, a server 16, a signal transmitter 17, a receiving terminal 18, and a computer 60.
One for each patient, the call terminal 14. The calling terminal 14 includes: a control unit (caller terminal control unit) 20, a communication unit (caller terminal communication unit) 22, a storage unit (caller terminal memory) 24, and an operation unit 26. Further, as shown in fig. 2, the calling terminal 14 includes: a case 27, a button 26 as an operation portion 26, and a power supply terminal 28. Since only the button 26 and the terminal 28 of the call terminal 14 are present on the outer surface of the housing 27, it is easy to improve the waterproof performance.
In addition, the calling terminal 14 may have a function of enabling electronic money transactions. Further, the calling terminal 14 may be a wearable terminal such as a smartphone, a watch type, a glasses type, or the like.
Hereinafter, the person (patient) carrying the calling terminal 14 will be referred to as the 1 st user.
The control section 20 controls signal transmission and reception via the communication section 22.
The communication section 22 can perform two kinds of communication. First, the transmission and reception of signals are performed by using the 1 st frequency band (UWB band). Second, the 2 nd band (433MHz band) is used to transmit and receive signals. Specifically, the communication unit 22 can receive the signal of the 1 st frequency band transmitted from the communication unit 32 of the fixed equipment 12, and can transmit the signal of the 1 st frequency band and the signal of the 2 nd frequency band to the communication unit 32 of the fixed equipment. More specifically, the communication section 22 may receive a UWB signal (which will be described later) from the stationary machine 12, and may transmit the UWB signal, the 1 st call signal, and the 2 nd call signal to the stationary machine 12.
The 1 st frequency band is, for example, a frequency band (UWB frequency band) used for UWB communication, and specifically, a frequency band of 3.1GHz-10.6GHz, 3.4GHz-4.8GHz, 7.25GHz-10.25GHz, 22GHz-29GHz, or the like can be given. The bandwidth of the 1 st band may be 500MHz or more, and may also be a bandwidth of 1.5GHz or more. The center frequency of the 1 st band is 1GHz or higher.
The 2 nd band is, for example, a 433MHz band whose frequency is lower than the 1 st band. The 2 nd band has a narrower bandwidth than the 1 st band. In addition, in the 2 nd band, the center frequency is less than 1 GHz. However, the center frequency of the 2 nd band may be less than 500 MHz.
The operation unit 26 is a button for receiving an operation (for calling another person) by the 1 st user. The control unit 20 generates a call signal based on the pressing operation of the operation unit 26, and transmits the call signal to the stationary machine 12 via the communication unit 22. Here, the call signal is a signal indicating that the operation unit 26 is operated, and is a signal indicating that the 1 st user is calling another person. The call signal may include information (identification information) capable of identifying each of the call terminals 14 (users of each of the call terminals 14).
Here, the identification information may be stored in the storage section 24 of the calling terminal 14. The identification information may be a manufacturing ID of the calling terminal 14. The correspondence between the identification information and the 1 st user (information on the name of the 1 st user identified by the identification information) may be stored in the storage unit 44 of the server 16.
The control unit 20 transmits a call signal using two frequency bands. Specifically, when the operation unit 26 is pressed, the control unit 20 transmits the 1 st call signal from the communication unit 22 using the 1 st frequency band, and transmits the 2 nd call signal from the communication unit 22 using the 2 nd frequency band. In other words, the call signal includes a 1 st call signal transmitted using a 1 st frequency band and a 2 nd call signal transmitted using a 2 nd frequency band.
The fixing machine 12 includes a control unit (fixing machine control unit) 30 and a communication unit (fixing machine communication unit) 32.
The communication section 32 can transmit and receive a signal using the 1 st frequency band (UWB band), and can transmit and receive a signal using the 2 nd frequency band (433MHz band). Specifically, the communication unit 32 can transmit a signal of the 1 st frequency band to the communication unit 22 of the calling terminal 14, and can receive a signal of the 1 st frequency band and a signal of the 2 nd frequency band from the communication unit 22 of the calling terminal 14. More specifically, the communication section 32 transmits a UWB signal (which will be described later) to the calling terminal 14, receives a 1 st calling signal, a 2 nd calling signal, and the UWB signal from the calling terminal 14, and also transmits the calling signal and distance information between the calling terminal 14 and the fixed machine 12 to the server 16.
The control section 30 controls signal transmission and reception via the communication section 32. Specifically, when the communication section 32 receives a 1 st call signal, a 2 nd call signal, or a UWB signal (which will be described later) from the calling terminal 14, the control section 30 transmits the call signal or information on the distance between the calling terminal 14 and the fixed machine 12 to the server 16.
A plurality of stationary machines 12 are provided in the facility 1. As shown in fig. 3, the facility 1 includes a plurality of rooms 2a to 2d, a common section 3, and a passage 4 connecting the rooms 2a to 2d and the common section 3. Rooms 2a to 2d include living rooms 5a to 5d and toilets 6a to 6 d. In the rooms 2a to 2d, partition walls 7 are provided between the rooms 5a to 5d and the toilets 6a to 6 d. In addition, doors are provided at the entrances of the rooms 2a to 2d (between the rooms 2a to 2d and the passage 4) and at the entrances of the toilets 6a to 6d (between the rooms 5a to 5d and the toilets 6a to 6 d).
Each room 2a to 2d becomes a ward where the 1 st user stays, and a bed is provided in each room 2a to 2 d. In addition, the toilets 6a to 6d may be accompanied by bathrooms. The sharing unit 3 is a space shared by the users in the rooms 2a to 2d and other people (doctors, hospital visitors, etc.). Here, each of the rooms 2a-2d is living by one 1 st user. In other words, each of rooms 2a-2d corresponds to a 1 st user. Therefore, rooms 2a-2d correspond to multiple users.
The stationary machines 12 are provided one in each of the rooms 2a-2 d. Specifically, the stationary machine 12 is installed in the living rooms 5a to 5d of the rooms 2a to 2d, but not in the toilets 6a to 6 d. That is, the rooms 2a to 2d have a plurality of spaces 5a to 5d and 6a to 6d divided by the partition walls 7, but the plurality of spaces 5a to 5d and 6a to 6d include the spaces 5a to 5d provided with the fixed machinery 12 and the spaces 6a to 6d not provided with the fixed machinery 12. Further, a plurality of fixtures 12 may be provided in one passage 4 and the common portion 3.
In the present embodiment, the fixing machine 12 is provided on the ceiling, but may be provided on a wall or the like.
The transmitter 17 includes a control unit (transmitter control unit) 100 and a communication unit (transmitter communication unit) 102.
When a call from the calling terminal 14 occurs, the communication unit 102 transmits information necessary for the terminal to display (notify) the call to the receiving terminal 18. This will be described in detail later. Here, the control section 100 also controls signal transmission and reception via the communication section 102.
A plurality of signal transmitters 17 are provided in the facility 1. Here, the fixed machine 12 and the signal transmitter 17 may be provided as one body, and the fixed machine 12 may also function as the signal transmitter 17.
Each of the persons (in the present embodiment, doctors, nurses, etc.) who receive a call from the calling terminal 14 has 1 receiving terminal 18. Here, the receiving terminal 18 includes: a control unit (control unit of the receiving terminal) 112, a communication unit (communication unit of the receiving terminal) 114, and a display unit (display unit of the receiving terminal) 116. As shown in fig. 7, the receiving terminal 18 further includes a housing 120 and a terminal 122 for power supply.
The receiving terminal 18 may have a function of enabling electronic money transactions. The receiving terminal 18 may be a portable calling terminal, a wearable terminal such as a watch type or a glasses type, or a card type. A general-purpose smart phone or the like may be used as the receiving terminal 18. However, it is preferred that a dedicated device for the system of the present invention be selected.
Hereinafter, a person (doctor, nurse, or the like) carrying the receiving terminal 18 is referred to as a 2 nd user.
The server 16 includes a control unit (server control unit) 40, a communication unit (server communication unit) 42, and a storage unit (server storage unit) 44. The communication unit 42 is connected to the plurality of fixed devices 12 (communication unit 32) and the plurality of signal transmitters 17 (communication unit 102) via a network (internet or intranet). The communication section 42 can receive the call signal transmitted from the communication section 32 and information on the distance between the calling terminal 14 and the fixed machine 12 via the network. Here, the communication unit 42 can also transmit various information to the communication unit 102 via a network.
The control section 40 controls signal transmission and reception via the communication section 42. The control unit 40 detects the position of the calling terminal 14 and a call from the calling terminal 14 based on a signal transmitted from the fixed equipment 12. Specifically, when the control section 40 receives the 1 st call signal or the 2 nd call signal, the control section 40 can detect a call from the calling terminal 14. In addition, when the control section 40 receives the 1 st call signal or the 2 nd call signal, the control section 40 determines which calling terminal 14 (which 1 st user) originated the call based on the identification information included in the call signal. Further, the control section 40 identifies the position of the calling terminal 14 based on the information on the distance between the calling terminal 14 and the fixed machine 12 transmitted from the plurality of fixed machines 12, and gives position information showing the position.
Hereinafter, an embodiment of acquiring position information (ranging) using UWB will be described. However, since a method of acquiring position information (ranging) using UWB is well known, the description herein will be simplified. In addition, methods other than those described herein may also be used to obtain location information.
First, as shown in fig. 4, the fixed machine 12 transmits the UWB signal from the communication unit 32 to the communication unit 22 of the calling terminal 14. At this time, the time for performing this transmission is "T1". However, the UWB signal here is a pulse signal having a frequency component of the 1 st band. In other words, the UWB signal is a signal transmitted using the 1 st frequency band.
Next, the communication unit 22 of the calling terminal 14 receives the UWB signal transmitted from the fixed unit 12. The time at which this reception is made is assumed to be "T2".
After a predetermined time has elapsed since the communication unit 22 received the UWB signal, the calling terminal 14 transmits the UWB signal (position signal) from the communication unit 22 to the communication unit 32 of the fixed unit 12 as a response to the received UWB signal. Assume that the time for performing this transmission is "T3".
Thereafter, the communication unit 32 of the fixed equipment 12 receives the UWB signal (position signal) transmitted from the calling terminal 14. The time at which this reception is performed is assumed to be "T4".
At this time, if the calling terminal 14 has not (almost) moved between the time T1 and the time T4, the time (T2-T1) at which the UWB signal transmitted from the fixed set 12 reaches the calling terminal 14 is the same as: the time (T4-T3) when the UWB signal transmitted from the calling terminal 14 arrives at the fixed unit 12 is the same time "Td". Here, Td ═ 2 ═ Td ((total time from when the fixed equipment 12 transmits the UWB signal to when the calling terminal 14 receives the response) - (time Ta required from when the calling terminal 14 receives the UWB signal to when the response is transmitted))/2 ═ T4-T1) - (T3-T2). Further, if the propagation speed of the UWB signal is the speed of light c, the distance d between the fixed machine 12 and the calling terminal 14 can be expressed as (d ═ Td × c). Therefore, the distance between the fixed machine 12 and the calling terminal 14 can be calculated by grasping Ta in advance, or measuring T1 and T4 (time interval from T1 to T4) by finding Ta in advance. However, the calculation of the distance d may be performed by the control unit 30 of the stationary machine 12 or may be performed by the control unit 40 of the server 16.
When receiving a UWB signal (position signal) from the calling terminal 14, the fixed machine 12 transmits information on the distance d (information on the distance d itself or information for calculating the distance d) to the server 16. The server 16 then calculates the location of the calling terminal 14 based on this information. Specifically, the information on the distance d is transmitted from the three fixed stations 12 (UWB signal transmission and reception with the calling terminal 14) to the server 16. The server 16 calculates position information from the information of the distance d (transmitted from the three fixed machines 12). That is, if the distance between each of the three different points (the location where the fixed machine 12 is provided) and a specific calling terminal 14 is known, the location of a specific calling terminal 14 can be determined, so that the location information of the calling terminal 14 can be obtained.
In calculating the position information, it is not always necessary to obtain the distances between the three fixed machines 12 and the calling terminal 14. For example, the positional information may also be calculated from the positional relationship between the two fixed machines 12 and the calling terminal 14 (the distance between the fixed machine 12 and the calling terminal 14 and the angle formed by the fixed machine 12 and the calling terminal 14 (the direction in which the calling terminal 14 is observed from the fixed machine 12)). That is, if there is information indicating the positional relationship between at least two fixed machines 12 and the calling terminal 14, the server 16 can grasp the position (coordinates) of the calling terminal 14 to some extent based on the information. If there are three or more stationary machines 12, the position of the calling terminal 14 can be accurately grasped. Further, if the information desired to be used as the location information merely indicates whether the calling terminal 14 is within a predetermined range from the fixed machine 12 (e.g., whether the calling terminal 14 is in the rooms 2a-2 d), such information may also be acquired through UWB communication performed between one of the fixed machines 12 and the calling terminal 14.
In addition, when calculating the distance d between the fixed machine 12 and the calling terminal 14, it is not necessary to transmit both of the following signals: (1) transmission of UWB signals from the fixed machine 12 to the calling terminal 14; (2) transmission of UWB signals from the calling terminal 14 to the stationary 12. For example, if time synchronization is achieved between the fixed machine 12 and the calling terminal 14, the distance d may be calculated only by transmitting a UWB signal (position signal) from the calling terminal 14 to the fixed machine 12. That is, the UWB signal transmitted from the calling terminal 14 to the stationary machine 12 is position information for calculating the distance d between the calling terminal 14 and the stationary machine 12 and acquiring the position information of the calling terminal 14. However, the position information is not necessarily based on the transmission of the UWB signal from the fixed telephone 12 to the calling terminal 14. Further, the position information is not necessarily used for calculation of the position information together with the UWB signal transmitted from the fixed machine 12 to the calling terminal 14.
The location signal transmitted from the calling terminal 14 to the stationary 12 for obtaining the location information of the calling terminal 14 may itself have the location information. That is, for example, the calling terminal 14 may have a GPS function or the like, and may transmit position information obtained by the GPS function to the server 16. However, as described above, the configuration of calculating the position information based on the UWB signal or the like can simplify the configuration of the calling terminal 14 or the like, and more accurate position information can be obtained indoors.
In addition, the storage unit (area information storage unit) 44 of the server 16 registers area information on each area (formed by dividing the space in the facility 1 into a plurality of areas). In the system of the present example, as the area information, there are registered: an identification number (area number) 72 for identifying each area, a name (area name) 74 of each area, and information showing the range of each area. Here, the information indicating the range of each area is information indicating the correspondence relationship between a certain predetermined space (the predetermined space constitutes a part of the entire space of the facility 1) and each area. In other words, the information indicating the range of each area refers to a location (a position specified based on the position signal) indicated by position information (i.e., position information calculated based on the position signal transmitted from the calling terminal 14) and another information (the information indicates a correspondence relationship with the area to which the location belongs).
In the system of the present embodiment, the above-described area information may be set (registered) by means of a computer 60 (for example, a personal computer) connected to the server 16. As shown in fig. 1, the computer 60 includes a control section 62, a communication section 64, a display section 66, and an operation section 68.
However, the server 16 itself may also be used as part or all of the computer 60.
Here, the communication section 64 is connected to the communication section 42 of the server 16 via, for example, a network (internet or intranet). Further, the communication unit 64 can transmit and receive data to and from the communication unit 42 of the server.
The control section 62 controls signal transmission and reception via the communication section 64. The control unit 62 executes various calculations based on the operation of the operation unit 68 and the signal received by the communication unit 64, and transmits a signal from the communication unit 64 or causes the display unit 66 to perform a desired display based on the calculation result.
The display unit 66 may be, for example, a liquid crystal display or the like. The operation section 68 may be, for example, a mouse, a keyboard, a touch panel, or the like.
Hereinafter, a setting method of the area information will be described with reference to fig. 5 and 6. Here, fig. 5 and 6 show display screens of the display unit 66 for setting the area information.
When setting the area information, first, a list screen 70 as an initial screen is displayed on the display unit 66. As shown in fig. 5, the list screen 70 displays a list of currently registered areas. Specifically, on the list screen 70, an identification number 72 of each region, a region name 74 of each region, and the like are displayed. However, the display of the list screen 70 is performed based on the area information stored in the storage unit (area information storage means) 44 of the server 16.
The area displayed on the list screen 70 can be newly added by inputting various information (for example, the area name 74) for each area on a registration screen (not shown) displayed on the list screen 70 by pressing the addition button 80. The various information on the respective areas displayed on the list screen 70 can be corrected and added as needed by inputting the various information on the respective areas on an editing screen (which is not shown) that is displayed by pressing the editing button 82 displayed on the list screen 70.
On the area range setting screen 86 (displayed based on the operation of the area range setting button 84 displayed on the list screen 70), the range of each area displayed on the list screen 70 can be set by specifying the range. Specifically, first, if the area range setting button 84 of the list screen 70 on the display unit 66 is selected by operating the operation unit 68, the display unit 66 displays the area range setting screen 86 on fig. 6.
A map (plan view) of the facility 1 is displayed on the area range setting screen 86. However, the maps displayed on the area range setting screen 86 may be prepared in plural for each predetermined range (for example, each building or floor) of the facility 1, and the respective maps may be selected and displayed. During the display of the area range setting screen 86, the computer 60 is set to be operable with the operation unit 68 and is also operable to receive an operation to draw the graphic 90 on the map. That is, by operating the operation unit 68 while the area range setting screen 86 is displayed, the operation of drawing the graphic 90 on the map can be performed. Here, the graphic 90 is, for example, a polygon, may be a graphic surrounding a predetermined range on a map, and may be a circle or the like. Then, the range surrounded by the graphic 90 on the map is set (defined) as the range of each area. In the system of the present embodiment, for example, by using a mouse as the operation portion 68, the respective vertices 91 of the polygon are prepared in a certain order, and the figure 90 can be drawn. Further, the figure 90 may be deformed by dragging and moving each vertex 91 of the figure 90. In the system of the present embodiment, for example, coordinate information (numerical value of coordinates) 92 of the vertex 91 of the figure 90 may be directly input by using a keyboard as the operation unit 68, or the figure may be drawn in accordance with the direct input of the coordinate information. That is, a predetermined coordinate system is set on the map displayed on the area range setting screen 86, and thus each point on the map can be displayed by the coordinates in the coordinate system. Further, in the system of this embodiment, the coordinate information 92 of each vertex 91 is displayed at a position corresponding to each vertex 91 of the graphic 90 drawn on the map.
In fig. 6, the graphic 90 is represented by a dotted line, but the graphic 90 may also be drawn by a solid line or the like having an obvious color (e.g., a color such as red or orange that is not used in the map).
When a predetermined range on the map is selected on the area range setting screen 86, the selected range is set (defined) as an area range. In other words, on the area range setting screen 86, once a graphic surrounding a predetermined area on the map is drawn, and when the graphic is determined (for example, a login button displayed on the area range setting screen 86 is pressed (not shown)), a range surrounded by the graphic is set (defined) as an area range.
The information on the respective areas includes information of the respective area ranges (input in the computer 60). Such information is transmitted to the server 16 and stored as area information in the storage section (area information storage section) 44.
As is apparent from the above description, in the present embodiment, the computer 60 (control section 62) detects an operation around a predetermined range on the map (displayed on the display section 66), and this operation is performed by the operation section 68 (area information setting operation section). The server 16 (storage unit 44) executes the storage process and stores the predetermined range as the area range. The computer 60 (control unit 62) receives input of coordinate information of the map displayed on the display unit (map display unit) 66, and this operation is performed by the operation unit 68 (area information setting operation unit). The server 16 (storage unit 44) executes the storage process and stores the predetermined range as a predetermined area range. Here, the predetermined range is a predetermined range on the map specified by the input coordinate information.
When the control section 40 of the server 16 determines the position of the calling terminal 14 based on the information on the distance (i.e., the distance between the calling terminal 14 and the fixed machine 12 transmitted from the fixed machine 12) and, at the same time, gives position information showing the position, the control section 40 of the server 16 determines an area where the calling terminal 14 exists from among a plurality of areas based on the position information and the position information stored in the storage section 44. That is, the server 16 may function as a location area identification section that identifies an area where the calling terminal 14 exists from among a plurality of areas based on the position information and the area information.
Specifically, when the server 16 (location area identifying unit) generates the position information based on the information on the distance between the calling terminal 14 and the fixed equipment 12 transmitted from the fixed equipment 12, the server identifies the location area indicated by the position information based on the area information stored in the storage unit 44. In addition, the server 16 (location area identifying section) may also extract the area name 74 of the identified area.
Hereinafter, a call starting from the calling terminal 14 will be described.
First, when the operation unit 26 is operated, the calling terminal 14 transmits a calling signal from the communication unit 22 to the communication unit 32 of the stationary machine 12. Specifically, the calling terminal 14 transmits the 1 st call signal using the 1 st frequency band, and transmits the 2 nd call signal using the 2 nd frequency band.
Next, the communication unit 22 of the fixed equipment 12 receives the 1 st call signal and/or the 2 nd call signal transmitted from the calling terminal 14, respectively. Thereafter, the fixed machine 12 transmits the received call signal to the server 16. Here, the fixed machine 12 may receive only one of the 1 st call signal and the 2 nd call signal. That is, for example, when the user presses the operation portion 26 in the toilet 6c of the room 2c, since the partition wall 7 exists between the user (call terminal 14) and the stationary machine 12 in the living room 5c, the 1 st call signal transmitted using the 1 st frequency band may be blocked by the partition wall 7 and thus cannot reach the stationary machine 12 (see fig. 3). However, even in this case, since the 2 nd call signal is transmitted using the 2 nd frequency band in the call system of the present embodiment, the 2 nd call signal can reach the fixed machine 12. Thus, the fixed machine 12 can transmit at least one of the 1 st call signal and the 2 nd call signal to the server 16. However, when the fixed machine 12 receives the 1 st call signal and the 2 nd call signal, it is not necessary to transmit both signals to the server 16. For example, a signal may be sent indicating that one of two call signals has been received.
When the server 16 receives a call signal from the fixed machine 12, the server 16 detects a call from the calling terminal 14 based on the received call signal. Further, when the server 16 receives the call signal from the fixed machine 12, the server 16 generates position information showing the current position of the calling terminal 14 based on the information on the distance d transmitted from the fixed machine 12, and identifies the area where it is located. Further, the server 16 identifies the calling terminal 14 (1 st user) that has made the call based on the identification information contained in the call signal. When the server 16 detects a call from the calling terminal 14, identifies the calling terminal 14 (1 st user) that has made the call, and identifies the area in which the calling terminal 14 is located, the server 16 transmits this information of the existing call to the receiving terminal 18 via the signal transmitter 17, and transmits information about the identified 1 st user and the area in which it is located.
The control unit 112 of the receiving terminal 18 notifies that there is a call when it receives the above information, that is, when there is a call from the calling terminal 14 (when the calling terminal 14 transmits a call signal and a location signal). Specifically, as shown in fig. 7, control unit 112 causes display unit 116 to display the wording of "emergency call" to notify that there is a call. At the same time, characters indicating the present area, for example, "room 3022 of the third floor", are displayed by the server 16 serving as the present area recognition unit. Further, the control section 112 causes the display section 116 to display the name of the 1 st user and the time when the call is made. However, the call origination time displayed on the display portion 116 may be acquired by any one of the calling terminal 14, the server 16, the receiving terminal 18, the fixed machine 12, and the signal transmitter 17.
However, the receiving terminal 18 may have a speaker or vibration function or the like, and when there is a call from the calling terminal 14, the existing call may be notified by sound (alarm) or vibration.
The system 10 of the present embodiment includes: a server 16, a plurality of stationary machines 12 disposed at predetermined locations and capable of communicating with the server 16, and a call terminal 14 capable of communicating with the stationary machines 12. The calling terminal 14 can transmit the 1 st call signal and the UWB signal (position signal) to the fixed machine 12 using the 1 st frequency band, and transmit the 2 nd call signal using the 2 nd frequency band having a frequency lower than the 1 st frequency band. The server 16 may determine the location of the calling terminal 14 based on UWB signals received by the fixed telephones 12 and may recognize calls originating from the calling terminal 14 based on 1 st or 2 nd call signals received by the fixed telephones 12. Since the position of the calling terminal 14 can be determined from the position signal transmitted using the 1 st frequency band (UWB band) on the high frequency side, the position of the calling terminal 14 can be accurately determined. Further, even when the fixed equipment 12 cannot receive the 1 st call signal transmitted using the 1 st frequency band on the high frequency side, the fixed equipment 12 can receive the 2 nd call signal transmitted using the 2 nd frequency band (433MHz band) on the low frequency side. To this end, the server 16 may identify a call from the calling terminal 14 based on the 2 nd call signal. Here, since the center frequency of the 1 st band is 1GHz or more, the accuracy of the acquired position information is high. Further, since the center frequency of the 2 nd band is less than 1GHz, the influence of the partition wall 7 on the transmission of the call signal can be reduced.
A stationary machine 12 is provided in the facility 1. The installation 1 comprises rooms 2a-2d, which rooms 2a-2d in turn comprise a number of spaces 5a-5d and 6a-6d separated by partition walls 7. One fixed machine 12 is provided inside each of the rooms 2a to 2d, and a plurality of fixed machines 12 are provided outside the rooms 2a to 2 d. Therefore, outside the rooms 2a to 2d, UWB signals (position signals) transmitted from the calling terminal 14 can be received by the plurality of fixed machines 12, and the position of the calling terminal 14 can also be accurately determined. Further, in the system 10 of the present embodiment, by means of a plurality of stationary machines 12 provided outside the rooms 2a to 2d and a single stationary machine 12 provided inside the rooms 2a to 2d, it is possible to grasp whether these stationary machines are inside or outside the rooms 2a to 2 d. Further, by reducing the number of the stationary machines 12 provided inside the rooms 2a to 2d, the installation cost of the stationary machines 12 can be reduced. In addition, since rooms 2a to 2d have a plurality of spaces partitioned by partition wall 7, although the 1 st band signal transmitted from call terminal 14 to stationary machine 12 may be blocked by partition wall 7, with system 10 of the present embodiment, the transmission of the 2 nd call signal is using the 2 nd band on the low frequency side which is not easily affected by partition wall 7. Therefore, even if there is a partition wall 7 between the call terminal 14 and the fixed machine 12, a desired call can be carried out.
However, when the server 16 detects the position of the calling terminal 14 based on information transmitted from the plurality of fixed machines 12, the server 16 may store position information showing the position in the storage section 44. Further, in this case, the past position information may be stored in the storage unit 44 together with the position information acquired this time, and at the same time, the time at which the position information is acquired may also be stored in association with each position information. By so doing, information on the movement route or the like of the calling terminal 14 can be obtained.
The acquisition of the position information may be performed when the calling terminal 14 issues a call signal (when the operation unit 26 is operated), or may be performed at predetermined time intervals (for example, every several seconds or every several minutes). That is, the notified area (position information) (when the calling terminal 14 is notified of a call) may be acquired based on the operation of the operation unit 26 or may be acquired at time intervals.
Here, the system of the present embodiment includes: a signaling calling terminal 14 capable of transmitting a calling signal and a location signal capable of identifying a location of the calling terminal 14; a region information storage section 44 that stores region information (i.e., region information about a space in the facility 1 that has been divided into a plurality of regions); a location area identification unit 16 that identifies an area in which the calling terminal 14 exists from among the plurality of areas based on the position information and the area information; receiving terminal 18 having display section 116. When the calling terminal 14 transmits the calling signal and the position signal, the display section 116 displays that the calling of the calling terminal 14 can be recognized and displays that the area (i.e., the area recognized by the area recognition section 16) can be notified. Therefore, when the calling signal and the position signal are transmitted from the calling terminal 14, the display portion 116 of the receiving terminal 18 is displayed to recognize the call that has occurred and also to notify the area (i.e., the area recognized by the area recognizing portion 16). That is, information indicating the area where the user of the calling terminal stays (i.e., the area where the user of the calling terminal stays) is displayed on the display unit 116 from among a plurality of preset areas. For this reason, it is possible to easily recognize from the receiving terminal where the call is coming.
The range of each area may be arbitrarily set, and for example, by setting an area for each room, the room in which the 1 st user is located can be identified. Further, for example, when the public place 3 is a restaurant, by setting an area for each predetermined range around each table in the restaurant, it is possible to identify which table (near which table) the 1 st user is seated at. Further, for example, by setting the respective areas so that the passage 4 is divided into a plurality of areas, it is possible to identify in which part of the passage 4 the 1 st user is.
Further, the system of the present embodiment includes a computer 60 capable of setting the area information stored in the area information storage section 44. The computer 60 includes a map display unit 66 that displays a map of the facility 1 and area information, and an area information setting operation unit 68 that accepts an operation to set area information, and is capable of setting the range of each area based on an operation (i.e., an operation performed by using the area information setting operation unit 68) that surrounds a predetermined range on the map (displayed on the map display unit 66). In addition, the area information setting method of the present embodiment includes a detection step and a setting step. The detection step is performed by using the area information setting operation portion 68 to detect a surrounding operation of a predetermined range on the map displayed on the map display portion 66. The setting step sets the predetermined range as a predetermined area range. Therefore, the range of each area can be set by surrounding a predetermined range on the map (displayed on the map display unit 66), and therefore the range of each area can be arbitrarily set. Further, since the range of each region can be intuitively set, the work becomes relatively easy.
Further, the system of the present embodiment further includes a computer 60 capable of setting the area information stored in the area information storage section 44. The computer 60 includes a map display unit 66 that displays a map of the facility 1. The computer 60 further includes an area information setting operation unit 68 that accepts an operation for setting area information. Therefore, the computer 60 can set the range of each area based on the coordinate information (input through the area information setting operation portion) associated with the map (displayed on the map display portion 66). In addition, the area information setting method of the present embodiment includes an accepting step and a setting step. The accepting step is performed by using the area information setting operation portion 68, and accepts an input operation of coordinate information (associated with the map displayed on the map display portion 66). The setting step sets the range of the predetermined area based on the coordinate information that has been input. Therefore, by setting the range of each region by inputting coordinate information related to the map displayed on the map display unit 66, the range of each region can be arbitrarily set. Further, since the range of each region can be specified by coordinates, the range of each region can be specified more accurately.
However, the above-described embodiments are merely examples for implementing the present invention. Therefore, the present invention is not limited to the above-described embodiments, and may be changed by replacing or deleting the respective constituent elements within the scope not departing from the spirit of the present invention.
