JP 2004-31289 A

  However, when a wireless ID tag reader is fixedly installed in a building (wall or floor) as in the past, it is necessary to re-install the wireless ID tag reader every time the factory line is replaced or renovated. It was. Such re-installation has been a problem because it requires a lot of labor and cost.

  Therefore, the present invention solves these problems, and does not require re-installation of the wireless ID tag reader when changing the factory line, refurbishing work, changing the system, etc., that is, when changing the layout or design in the building. The purpose is to provide methods and methods.

  A first aspect of the present invention is a position detection system, which includes a plurality of wireless ID tags, a wireless ID tag reader, wireless transmission means, wireless reception means, and storage means. The wireless ID tag is fixedly installed at a predetermined position. Further, the wireless ID tag has a position ID indicating the installed position.

  The wireless ID tag reader moves with the moving body. For example, the wireless ID tag reader may be attached to the mobile body, may be attached to the mobile body, or may be attached to the mobile body. The wireless ID tag reader reads the position ID from the wireless ID tag.

The wireless transmission means moves together with the moving body. Similarly to the wireless ID tag reader, the wireless transmission means may be attached to the mobile body, may be attached to the mobile body, or may be attached to the mobile body. The wireless transmission unit may be configured integrally with the wireless ID tag reader or may be configured as a separate device. The wireless transmission means receives the position ID from the wireless ID tag reader. And a wireless transmission means transmits this position ID and the moving body ID corresponding to the said moving body to another apparatus by wireless communication. This mobile body ID may be stored in a wireless ID tag reader and delivered to the wireless transmission means together with the position ID from the wireless ID tag reader. Moreover, mobile body ID may be memorize | stored in a wireless transmission means. Further, the mobile unit ID may be stored in a device other than the wireless ID tag reader and the wireless transmission unit. In this case, the wireless transmission unit may read the mobile body ID when performing the wireless communication.

  The wireless reception unit receives the position ID and the mobile unit ID from the wireless transmission unit by wireless communication. And a memory | storage means matches and memorize | stores position ID and mobile body ID which were received by the radio | wireless receiving means.

  In a conventional system, a wireless ID tag reader is fixedly installed, and a mobile body is provided with a wireless ID tag. In contrast, in the system according to the first aspect of the present invention, the wireless ID tag is fixedly installed, and the wireless ID tag reader moves together with the moving body. Generally, a wireless ID tag is cheaper than a wireless ID tag reader. For this reason, the wireless ID tag reader is often installed at a low density at a minimum necessary location. On the other hand, inexpensive wireless ID tags can be installed in advance at a high density up to a place that is initially considered unnecessary. For this reason, even when the arrangement change or the design change is made in the building, it is possible to flexibly cope with only the wireless ID tag installed in advance.

  In other words, when wireless ID tag readers are installed at a low density, the role of one wireless ID tag reader is large, so consider changing the layout so that each wireless ID tag reader will not stop functioning due to the layout change. Need to be done. In addition, it is difficult in terms of cost to install a wireless ID tag reader in advance in a place where a position detection system was originally considered unnecessary. Therefore, when a new position detection system is provided in such a place, it is necessary to install a new wireless ID tag reader. On the other hand, wireless ID tags with low costs can be installed in high density in advance. For this reason, even if some of them do not function due to the change in arrangement, the functions can be covered by other wireless ID tags in the vicinity. In addition, it is possible to install a wireless ID tag in a place where it was originally thought that a position detection system was unnecessary, and it is easy to introduce a new position detection system in such a place. It becomes.

  A second aspect of the present invention is a position detection system, which includes a plurality of wireless ID tags, a wireless ID tag reader, wireless transmission means, wireless transmission / reception means, wireless reception means, and storage means. The wireless ID tag, wireless ID tag reader, and storage means in the second aspect of the present invention are configured similarly to the wireless ID tag, wireless ID tag reader, and storage means in the first aspect of the present invention. For this reason, descriptions of the wireless ID tag, wireless ID tag reader, and storage means in the second aspect of the present invention are omitted.

  The wireless transmission means in the second aspect of the present invention is different from the wireless transmission means in the first aspect in that the position ID and the mobile body ID are transmitted to other devices by the first wireless communication.

  The wireless transmission / reception means moves together with the moving body. The wireless transmission / reception means may be attached to the mobile body, may be attached to the mobile body, or may be attached to the mobile body. The wireless transmission / reception means is not configured integrally with the wireless transmission means. The wireless transmission / reception means receives the position ID and the mobile body ID transmitted from the wireless transmission means by the first wireless communication. Further, the wireless transmission / reception means determines whether or not the previously received position ID is the same as the currently received position ID. Then, when the position ID received last time and the position ID received this time are different, the wireless transmission / reception means replaces the position ID (that is, the position ID received this time) and the mobile body ID by the second wireless communication. To the device. In the above description, the mobile unit ID is stored in the wireless ID tag reader or the wireless transmission unit, but the mobile unit ID may be stored in the wireless transmission / reception unit. In this case, the wireless transmission means transmits only the position ID, and the wireless transmission / reception means receives only the position ID from the transmission means by the first wireless communication.

The wireless reception means in the second aspect of the present invention is different from the wireless reception means in the first aspect of the present invention in that the position ID and the mobile body ID are received from the wireless transmission / reception means by the second wireless communication. The first wireless communication and the second wireless communication may be implemented by different communication methods, or may be implemented by the same communication method.

  According to the second aspect of the present invention, the data (position ID, mobile object ID) transmitted from the wireless transmission means is not transmitted directly to the wireless reception means but is transmitted via the wireless transmission / reception means. . Further, since the wireless transmission means and the wireless transmission / reception means move together with the same mobile body, the communication distance between the wireless transmission means and the wireless transmission / reception means is shorter than the distance between the wireless transmission means and the wireless reception means. . Therefore, the wireless transmission means in the second aspect of the present invention only needs to secure a shorter communication distance than the wireless transmission / reception means in the first aspect of the present invention. For this reason, power consumption in the wireless transmission means can be reduced. The first wireless communication can be realized by an inexpensive mounting method with a short communication distance.

  According to the second aspect of the present invention, the wireless transmission / reception means performs communication by the second wireless communication with respect to the wireless reception means only when the position ID changes. For this reason, it is possible to reduce the number of communications, and it is possible to reduce the processing load on the wireless reception means and the storage means.

  Also according to the second aspect of the present invention, the same effects as those of the first aspect of the present invention can be achieved.

  According to a first aspect and a second aspect of the present invention, there is provided a vibration power generation apparatus that moves together with a mobile body, generates power based on vibration generated by the movement of the mobile body, and supplies power to the wireless ID tag reader and the wireless transmission means. Further, it may be configured to include. In this case, the wireless ID tag reader and the wireless transmission means may be configured to operate with electric power supplied from the vibration power generator.

  With this configuration, the wireless ID tag reader and the wireless transmission unit can operate without being supplied with power from a device other than the vibration power generation device. Therefore, in the position detection system configured as described above, it is not necessary to supply power from outside the system to the wireless ID tag reader and the wireless transmission means that move together with the moving body. Therefore, the wireless ID tag reader and the wireless transmission means can be operated semipermanently.

  In addition, as described above, the moving body in the first aspect and the second aspect of the present invention may be a human. In this case, the first aspect and the second aspect of the present invention may be configured so as to further include a pressure power generation device provided in a portion to which a load due to the human weight is applied among the portions of the human footwear. At this time, the pressure power generation device generates power by a load generated when the footwear comes in contact with the ground, and supplies power to the wireless ID tag reader and the wireless transmission means. Moreover, when comprised in this way, a wireless ID tag reader and a wireless transmission means operate | move with the electric power supplied from a vibration electric power generating apparatus.

  Also when comprised in this way, a radio | wireless ID tag reader and a radio | wireless transmission means can operate | move without the need to supply electric power from apparatuses other than a vibration electric power generating apparatus. Therefore, in the position detection system configured as described above, it is not necessary to supply power from outside the system to the wireless ID tag reader and the wireless transmission means that move together with the moving body. Therefore, the wireless ID tag reader and the wireless transmission means can be operated semipermanently.

The place where the first aspect and the second aspect of the present invention are applied may be provided with a permission area where the mobile body is allowed to enter and a prohibited area where the mobile body is not allowed to enter. In this case, the first aspect and the second aspect of the present invention provide a table storage unit that stores a table in which permission / denial IDs, position IDs, and mobile body IDs indicating either permitted areas or prohibited areas are associated with each other. It may be configured to include. Furthermore, in this case, the first aspect and the second aspect of the present invention may be configured to further include a determination unit and an output device. The determination unit obtains the permission ID corresponding to the position ID and the mobile body ID received by the wireless reception unit from the storage unit, and determines the output content based on the content of the permission ID. Then, the output device performs output according to the determination result by the determination means. The output device may be configured using, for example, a display device, an audio output device, a light emitting device, or the like. In addition, for example, when the permission / denial ID indicates that the permission area is indicated, the output device may be configured to display / speak a message prompting entry. Further, for example, when the permission / denial ID indicates a prohibited area, the output device may be configured to display / speak a message prohibiting entry, or may be configured to emit a warning sound. Alternatively, it may be configured to prompt a warning by emitting light.

  A third aspect of the present invention is footwear worn on a human foot, and includes a vibration power generation device, an ID tag reader, and transmission means. The vibration power generation apparatus generates power by vibration generated by the action of a human being worn. The wireless ID tag reader operates with the electric power generated by the vibration power generator. Then, the wireless ID tag reader reads the position ID from the wireless ID tag. This wireless ID tag is fixedly installed at a predetermined position, and has a position ID indicating the installed position. The transmission means operates by the electric power generated by the vibration power generator. Then, the transmission means transmits the position ID read by the wireless ID tag reader to another device.

  The footwear which is the third aspect of the present invention can be applied to the first and second aspects of the present invention described above. Further, the footwear according to the third aspect of the present invention can be operated semipermanently without supplying electric power from the outside, since the wireless ID tag reader and the transmission means operate with electric power from the vibration power generator.

  A fourth aspect of the present invention is footwear worn on a human foot, and includes a pressure power generation device, an ID tag reader, and transmission means. The pressure power generation device is provided in a portion to which a load due to human weight is applied, and generates power by the load.

[First embodiment]
Hereinafter, the position detection system 1a which is 1st embodiment of the position detection system 1 is demonstrated.

〔System configuration〕
FIG. 1 is a diagram illustrating a system configuration example of the position detection system 1a. The position detection system 1a includes footwear 2, a wireless ID tag 3, a wireless reception unit 4, a network 5, and a server 6a. Hereinafter, each component will be described.

  FIG. 2 is a diagram illustrating a specific configuration example of the footwear 2. The footwear 2 includes a vibration power generation device 21, a wireless ID tag reader 22, and a wireless transmission unit 23. As long as the footwear 2 can include the vibration power generation device 21, the wireless ID tag reader 22, and the wireless transmission unit 23, the footwear 2 may be configured by using any form of footwear such as shoes, sandals, and slippers.

The vibration power generation device 21 converts vibration energy generated when the footwear 2 is worn by a person into electrical energy. That is, the vibration power generation device 21 generates power by using vibration generated when a person walks. The vibration power generation device 21 can be realized, for example, by applying the technique described in the following paper.
Daisuke Takii, Kimihiko Nakano, Shun Saito, Zeno Matsunaga “Design of small vibration generators using arc-shaped rails” Proceedings of the Annual Meeting of the Japan Society of Mechanical Engineers, Vol. 5, no. 03-1, 2003-8, pp. 283-284.

  The vibration power generator 21 supplies the generated power to the wireless ID tag reader 22 and the wireless transmission unit 23.

  The wireless ID tag reader 22 operates with electric power supplied from the vibration power generator 21. The wireless ID tag reader 22 reads data (position ID) from a wireless ID tag 3 (details will be described later) provided on the floor or under the floor. The wireless ID tag reader 22 may be configured using, for example, an RFID tag reader. The wireless ID tag reader 22 passes the position ID read from the wireless ID tag 3 to the wireless transmission unit 23. Further, the wireless ID tag reader 22 stores the individual mobile body ID in a storage device (not shown). The mobile body ID is an ID assigned so as not to overlap each footwear 2. The footwear 2 can be uniquely identified by the moving body ID. The mobile body ID may be an ID assigned to a user who uses the footwear 2 instead of the footwear 2. Then, the wireless ID tag reader 22 passes this mobile body ID to the wireless transmission unit 23 together with the position ID read from the wireless ID tag 3.

  The wireless transmission unit 23 is operated by electric power supplied from the vibration power generator 21. The wireless transmission unit 23 transmits the data (position ID and mobile body ID) received from the wireless ID tag reader 22 to the wireless reception unit 4. Data transmission / reception is performed between the wireless transmission unit 23 and the wireless reception unit 4 by wireless communication. The wireless transmission unit 23 may be realized by applying a technology such as Bluetooth (registered trademark), wireless LAN, or HomeRF (Home Radio Frequency).

  The vibration power generation device 21, the wireless ID tag reader 22, and the wireless transmission unit 23 may be provided at the bottom of the footwear 2. In particular, since the wireless ID tag reader 22 needs to be installed so that the distance from the wireless ID tag 3 is short, it is desirable that the wireless ID tag reader 22 be provided at the bottom of the footwear 2. However, if feasible, each of the vibration power generation device 21, the wireless ID tag reader 22, and the wireless transmission unit 23 may be provided in any part of the footwear 2, and the installation location is not necessarily limited.

The wireless ID tag 3 is provided, for example, by being embedded in a floor on which a person walks wearing the footwear 2. The wireless ID tag 3 has a position ID that is data corresponding to the position where the wireless ID tag 3 is provided. FIG. 3 is a diagram illustrating an example of a floor on which the wireless ID tag 3 is provided. A plurality of wireless ID tags 3 are provided on the floor. Each wireless ID tag 3 includes, for example, an integer of 1 to n indicating the coordinate on the horizontal axis and an alphabetic character string indicating the coordinate on the vertical axis as the position ID. In this case, the position is indicated by an integer and an alphabetic character string. In this case, the alphabet character string may be a character string represented by a plurality of characters. Further, for example, it may be configured to further indicate a floor (number of floors), may be configured to indicate a section, or may be configured to indicate a building itself. That is, the position ID of the wireless ID tag 3 may be set in any format as long as the data can indicate the position.

  The wireless reception unit 4 receives data (position ID and mobile body ID) transmitted from the wireless transmission unit 23 of the footwear 2. The wireless reception unit 4 is configured to be capable of wireless communication with the wireless transmission unit 23. The wireless reception unit 4 may be realized by applying, for example, the wireless communication technology as described above, that is, for example, technology such as Bluetooth (registered trademark), wireless LAN, or HomeRF. The wireless reception unit 4 is provided in a facility such as a ceiling or a wall, for example.

  The wireless reception unit 4 has a network interface and is configured to be connectable to the network 5. The wireless reception unit 4 transmits the received data to the server 6a via the network 5. In addition, a plurality of wireless reception units 4 may be provided in one position detection system 1a.

  The network 5 is a network that connects at least the wireless reception unit 4 and the server 6a so that they can communicate with each other. It may be configured using a wired network (for example, a wired LAN), or may be configured using a wireless network (for example, a wireless LAN).

  The server 6a is configured using an information processing apparatus such as a personal computer or a workstation. The server 6a has a network interface and is configured to be connectable to the network 5. FIG. 4 is a diagram illustrating an example of functional blocks of the server 6a. The server 6 a includes a transmission / reception unit 61 and a storage unit 62.

  The transmission / reception unit 61 is a network interface for connecting to the network 5. The server 6 a transmits data to the network 5 via the transmission / reception unit 61 and receives data from the network 5.

  The storage unit 62 is configured using a volatile storage device or a nonvolatile storage device. The storage unit 62 stores the position ID and the moving body ID received via the transmission / reception unit 61 in association with each other. FIG. 5 is a diagram illustrating an example of a table stored in the storage unit 62. For example, as illustrated in FIG. 5, the storage unit 62 may store a set of a position ID and a moving body ID as one record. In this case, the storage unit 62 may store a serial number in association with each record. The number of records that can be stored in the storage unit 62 is not particularly limited, and may be freely set by a designer. Therefore, it is not necessary to be limited to three records as shown in FIG.

[System flow]
FIG. 6 is a flowchart showing the flow of processing in the position detection system 1a. Hereinafter, the flow of processing in the position detection system 1a will be described. First, the wireless ID tag reader 22 included in the footwear 2 reads the position ID from the wireless ID tag 3 (S1). Next, the wireless transmission unit 23 included in the footwear 2 transmits the position ID read by the wireless ID tag reader 22 and the mobile body ID corresponding to the footwear 2 to the wireless reception unit 4 (S2). When receiving the position ID and the mobile object ID, the wireless reception unit 4 transmits the received position ID and mobile object ID to the server 6a via the network 5 (S3). Then, the server 6a stores the position ID and the moving body ID received from the wireless reception unit 4 as a set in the storage unit 62 (S4).

[Action / Effect]
According to the position detection system 1a, the wireless ID tag reader is not installed in the facility (for example, the floor) as in the prior art, but by installing the wireless ID tag, the position of each moving body is determined by the server 6a. It is possible to accumulate in In this case, unlike the wireless ID tag reader 22, the wireless ID tag 3 is inexpensive and can be installed in high density in advance. For the same reason, the wireless ID tag 3 can be installed in advance in a place where the position detection system 1a is not initially planned. Therefore, even when an arrangement change or a design change occurs in the facility, the design of the position detection system 1a can be flexibly changed by using the wireless ID tag 3 installed in advance. For this reason, in the position detection system 1a, the arrangement | positioning change etc. of the wireless ID tag reader 22 are not required, and the cost which arises by arrangement | positioning change, a design change, etc. can be suppressed.

  The footwear 2 used in the position detection system 1 a includes a vibration power generation device 21. The wireless ID tag reader 22 and the wireless transmission unit 23 are operated by the power generated by the vibration power generation device 21. For this reason, it is not necessary to rely on other power sources in the operation of the footwear 2, and it is possible to operate it semipermanently.

[Modification]
The footwear 2 may be configured to supply power to the wireless ID tag reader 22 and the wireless transmission unit 23 by providing a pressure power generation device instead of the vibration power generation device 21. The pressure power generation device is provided in a portion to which a load due to human weight is applied, and generates power by the load. The part to which the load due to the human weight is applied corresponds to, for example, the bottom part of the heel of the footwear 2 or the bottom part of the toe.

[Second Embodiment]
Next, the position detection system 1b which is 2nd embodiment of the position detection system 1 is demonstrated.

〔System configuration〕
FIG. 7 is a diagram illustrating a system configuration example of the position detection system 1b. The position detection system 1 b includes footwear 2, a wireless ID tag 3, a wireless reception unit 4, a network 5, a server 6 a, and a wireless transmission / reception device 7. Hereinafter, the difference between the position detection system 1b and the position detection system 1a will be described.

  The position detection system 1b is greatly different from the position detection system 1a in that the position detection system 1b includes the wireless transmission / reception device 7. The wireless transmission / reception device 7 is configured using, for example, a mobile phone, a PHS (Personal Handyphone System), a PDA (Personal Digital Assistant) having a communication function, or the like. The wireless transmission / reception device 7 is accompanied by a user wearing the footwear 2. The wireless transmission / reception device 7 receives the position ID and the mobile body ID from the wireless transmission unit 23 included in the footwear 2 and transmits the received data to the wireless reception unit 4. The communication method performed by the wireless transmission / reception device 7 and the wireless transmission unit 23 and the communication method performed by the wireless transmission / reception device 7 and the wireless reception unit 4 may be the same or different. For example, the wireless transmission / reception device 7 and the wireless transmission unit 23 may be configured to communicate via Bluetooth (registered trademark), and the wireless transmission / reception device 7 and the wireless reception unit 4 may be configured to perform communication via a wireless LAN. Further, for example, the wireless transmission / reception device 7 and the wireless transmission unit 23 may be configured to communicate with each other via Bluetooth (registered trademark), and the wireless transmission / reception device 7 and the wireless reception unit 4 may also be configured to perform communication according to Bluetooth (registered trademark). good.

When receiving the position ID and the mobile object ID from the wireless transmission unit 23, the wireless transmission / reception device 7 determines whether or not the position ID and the mobile object ID should be transmitted to the wireless reception unit 4. For example, the wireless transmission / reception device 7 may store the position ID received from the wireless transmission unit 23 every time, and may determine that the position ID should be transmitted when the newly received position ID is different from the stored position ID. . In addition, when transmitting the position ID and the moving body ID to the wireless reception unit 4, the wireless transmission / reception device 7 stores the transmitted position ID, and the newly received position ID You may judge that it should transmit in different cases.

  The wireless transmission unit 23 and the wireless reception unit 4 included in the footwear 2 are configured to be able to realize communication with the wireless transmission / reception device 7. Moreover, about the other structure of the position detection system 1b, it becomes the structure similar to the position detection system 1a.

[System flow]
FIG. 8 is a flowchart showing the flow of processing in the position detection system 1b. Hereinafter, the flow of processing in the position detection system 1b will be described. First, the wireless ID tag reader 22 included in the footwear 2 reads the position ID from the wireless ID tag 3 (S5). Next, the wireless transmission unit 23 included in the footwear 2 transmits the position ID read by the wireless ID tag reader 22 and the mobile body ID corresponding to the footwear 2 to the wireless transmission / reception device 7 (S6). Based on the received position ID, the wireless transmission / reception device 7 determines whether the received position ID and mobile body ID need to be transmitted (S7). And when the radio | wireless transmission / reception apparatus 7 judges that transmission is required, it transmits the received position ID and mobile body ID to the radio | wireless receiving part 4 (S8). Note that the wireless transmission / reception device 7 does not perform transmission when it is determined that transmission is not necessary.

  When receiving the position ID and the mobile object ID, the wireless reception unit 4 transmits the received position ID and mobile object ID to the server 6a via the network 5 (S9). Then, the server 6a stores the position ID and the moving body ID received from the wireless reception unit 4 as a set in the storage unit 62 (S10).

[Action / Effect]
According to the position detection system 1b, the wireless transmission unit 23 and the wireless reception unit 4 included in the footwear 2 do not directly communicate with each other. That is, the wireless transmission unit 23 communicates with the wireless transmission / reception device 7, and the wireless reception unit 4 also communicates with the wireless transmission / reception device 7. In general, the physical position of the wireless transmission / reception device 7 is between the wireless transmission unit 23 and the wireless reception unit 4. For this reason, compared with the case where the wireless transmission unit 23 communicates with the wireless reception unit 4, the physical communication distance may be shorter when communicating with the wireless transmission / reception device 7. For this reason, the wireless transmission part 23 can suppress the power consumption required for communication. In addition, since the physical communication distance is shortened, the choice of communication technology that can be applied to the wireless transmission unit 23 is expanded, and the design can be made more flexibly.

  Further, according to the position detection system 1b, the wireless transmission / reception device 7 determines whether or not the transmission process of the position ID and the mobile body ID is necessary. For this reason, the communication volume which the radio | wireless receiving part 4 receives is reduced, As a result, the communication load in the radio | wireless receiving part 4, the network 5, and the server 6a is reduced.

[Modification]
A modification of the position detection system 1a may be applied to the position detection system 1b.

c includes footwear 2, a wireless ID tag 3, a wireless receiver 4, a network 5, a server 6 c, and an output device 8. Hereinafter, the difference between the position detection system 1c and the position detection system 1c will be described.

  The position detection system 1c is greatly different from the position detection system 1a in that it includes a server 6c instead of the server 6a and further includes an output device 8.

  FIG. 10 is a diagram illustrating an example of functional blocks of the server 6c. Server 6c differs from server 6a in that it further includes a determination unit 63. The determination unit 63 determines the instruction content to the output device 8 based on the position ID and the mobile body ID received via the transmission / reception unit 61. Specifically, the determination unit 63 determines the instruction content according to a determination table provided in a storage device (not shown).

  FIG. 11 is a diagram illustrating an example of a determination table. The determination table includes, for example, a plurality of records in which the position ID, the moving body ID, and the instruction content are associated with each other. Based on the received position ID and moving body ID, the determination unit 63 acquires the corresponding instruction content from the determination table. Then, the determination unit 63 transmits the acquired instruction content to the output device 8 via the transmission / reception unit 61. At this time, when there is no corresponding instruction content in the determination table, the determination unit 63 may be configured not to instruct the output device 8.

The output device 8 uses a display device such as a CRT (Cathode Ray Tube), a liquid crystal display or an EL (Electro-Luminescent) display, a sound output device such as a speaker or a siren, a light emitting device that blinks, blinks or lights. Configured. The output device 8 performs predetermined output according to the instruction content received from the server 6c. For example, when the received instruction content is warning 1, the light is turned on, and when the received instruction content is warning 2, the light is flashed to further alert the user and the voice output device It may be configured to sound a siren. As described above, the output device 8 may be configured to output by combining a plurality of output devices in accordance with the received instruction content, or configured to change the output method in one output device. May be.

[System flow]
FIG. 12 is a flowchart showing the flow of processing in the position detection system 1c. Hereinafter, the flow of processing in the position detection system 1c will be described. First, the wireless ID tag reader 22 included in the footwear 2 reads the position ID from the wireless ID tag 3 (S11). Next, the wireless transmission unit 23 included in the footwear 2 transmits the position ID read by the wireless ID tag reader 22 and the mobile body ID corresponding to the footwear 2 to the wireless reception unit 4 (S12). When receiving the position ID and the moving body ID, the wireless reception unit 4 transmits the received position ID and moving body ID to the server 6c via the network 5 (S13). Then, the server 6c stores the position ID and the moving body ID received from the wireless reception unit 4 as a set in the storage unit 62 (S14).

  Next, the server 6c acquires the instruction content from the determination table based on the received position ID and mobile body ID (S15). When the instruction content is acquired, the server 6c transmits the acquired instruction content to the output device 8 (S16). Then, the output device 8 performs output processing according to the instruction content (S17).

[Action / Effect]
According to the position detection system 1c, processing according to the position of the user of the footwear 2 is executed by the output device 8. The position detection system 1c can be applied to the following cases, for example.

  For example, the footwear 2 is created separately for persons concerned and for customers. In other words, the moving body ID indicating that the person is a participant is stored in the footwear 2 for the related person, and the moving body ID indicating that the person is the customer is stored in the footwear 2 for the customer. In addition, the district where the position detection system 1c is installed is a district where related persons are allowed to enter but a customer is not allowed to enter, and a customer is allowed to enter but a related person is not allowed to enter. , Both are divided into districts that are allowed to enter, and both are not allowed to enter. Then, the mobile body ID, the position ID in the above four categories, and the warning contents (that is, the instruction contents to the output device 8) are set in the determination table. By being configured in this way, it is possible to give an appropriate warning to a person who is about to approach an area where entry is prohibited according to the attribute (related party or customer) of the mobile object ID.

[Modification]
A modification of the position detection system 1a may be applied to the position detection system 1c. The position detection system 1c may be configured to further include the wireless transmission / reception device 7 in the position detection system 1b.
