Description

  The present invention provides a positioning system, a positioning terminal, a positioning terminal control method, a positioning terminal control program, and a positioning terminal control program in which a position notification can be performed indoors in a short time and with low power consumption. The present invention relates to a simple recording medium.

Conventionally, a GPS (Global Positioning System) device has been used as a positioning system for positioning using an artificial satellite. Examples of applications include car navigation systems and mobile phones, which are widely used today.
Since a signal transmitted from a GPS satellite is spread and modulated using a PN (Pseudo Noise) code, it takes at least several seconds to acquire orbit information of the GPS satellite included in the signal and perform positioning. . In a room where the signal strength is weak, positioning becomes difficult, and even when positioning is possible, the time required for positioning becomes very long.

  For this reason, various techniques have been proposed for performing positioning in a short time even in places with poor reception environments such as indoors. For example, in Patent Document 1, the GPS satellite acquisition speed is increased by providing a dedicated matched filter for initial acquisition of the GPS satellite, and the S / N of the received signal is reduced by cyclic integration of the output of the matched filter. An arrangement for improving sensitivity and improving sensitivity is disclosed.

Further, as a positioning system other than GPS, there is a system that performs positioning using the position of a base station of a communication system such as a mobile phone. In such a system, if the terminal device can receive signals transmitted from a plurality of base stations, positioning can be performed in a relatively short time even in a room.
Japanese Patent Laid-Open No. 2004-219076 (FIG. 1 etc.)

However, when GPS is used for positioning in a place with poor reception environment such as indoors, even with the configuration as in Patent Document 1, if the strength of the received signal is weak, positioning takes a long time and a large amount of power is required. There was a problem of consumption.
Moreover, in the positioning using the position of the base station, the accuracy of the obtained terminal device position is on the order of several hundreds of meters at the most, and there is a problem that it is far from GPS positioning when the conditions are good.

  Therefore, the present invention records a positioning system, a positioning terminal, a positioning terminal control method, a positioning terminal control program, and a positioning terminal control program capable of performing position notification in a short time and with low power consumption even indoors. An object is to provide a computer-readable recording medium.

According to the first aspect of the present invention, the object has a building position information providing device installed at a doorway of a building and a positioning terminal carried by a user, and the building position information providing device is a position of the building.

If not, it is achieved by a positioning system comprising position notification means for reading out the building position information from the terminal-side building position information storage means and notifying the position request program.

According to the configuration of the first invention, the building position information providing apparatus installed at the entrance of the building stores the building position information indicating the position of the building in the providing apparatus side building position information storage means. The building position information is not the position of the positioning terminal itself, but can be used as information indicating the position of the positioning terminal while the user of the positioning terminal is inside the building.
The building position information providing device has a wireless communication means on the providing device side, and when the user passes through the entrance of the building where the building position information providing device is installed, wireless communication with the positioning terminal is used.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiment described below is a preferred specific example of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

FIG. 1 is a schematic diagram showing a positioning system 1 or the like which is an embodiment of the positioning system of the present invention.
The positioning system 1 is an example of a positioning terminal, and is a small device carried by a user, such as a mobile phone, a PHS (Personal Handy-phone System) terminal, a PDA (Personal Digital Assistance), or a portable personal computer. It is an example of a portable terminal 100 and a building location information providing device, and is configured by gates 200 and 201 provided at entrances 18 and 19 of the building 16.

The mobile terminal 100 includes a communication device 102 (see FIG. 2), can wirelessly connect to the base station 12, and can communicate with the location management server 300 via the communication network 14.
The mobile terminal 100 includes a GPS device 108, and can receive positioning signals S1, S2, S3, and S4 transmitted from GPS satellites 10a, 10b, 10c, and 10d, and calculate the position of the mobile terminal 100. In the outdoor 20 where the received intensity of the positioning signal S1 or the like is sufficiently strong, a highly accurate position can be calculated in a relatively short time. However, in the indoor 22 of the building 16 where the positioning signal S1 or the like is blocked by the ceiling 24 or the wall 26 and the reception intensity becomes weak, it takes a long time to calculate the position, and the accuracy of the calculated position is also low. End up. In addition, after trying positioning for a long time, the position calculation often fails in the end. Therefore, it is not preferable to perform positioning by the GPS device 108 in the indoor 22 because it leads to waste of electric power.

  The mobile terminal 100 includes a short-range communication device 129 and can communicate wirelessly with the gate 200 or the gate 201 installed at the entrances 18 and 19 of the building 16. For example, when entering the indoor 22 of the building 16 from the entrance 18, the mobile terminal 100 acquires the position of the building from the gate 200 and stores it in the storage device 104 (see FIG. 2). For example, when a location information transmission request is received from the location management server 300 indoors, positioning by the GPS device 108 is not performed, and the building location information stored in the storage device 104 is transmitted to the location management server 300. Send.

The gates 200 and 201 have a short-range communication device 222 and can be connected to the short-range communication device 129 of the mobile terminal 100 wirelessly to transmit and receive information. When there is a response from the short-range communication device 129 of the mobile terminal 100, the short-range communication device 222 transmits the location information of the building 16 stored in the storage device 204 of the gates 200 and 201 to the mobile terminal 100.
A person who goes in and out of the building 16 always passes through the gate 200 or 201.

The location management server 300 is a general server computer having a communication function, and can communicate with the mobile terminal 100 via the communication network 14 and the base station 12.
The location management server 300 provides, for example, a location information service that displays the location of the mobile terminal 100 on a service user's terminal in real time. For this reason, in the location management server 300, a location request program is operating and frequently requests location information from the mobile terminal 100.

(Main hardware configuration of mobile terminal 100)
FIG. 2 is a schematic diagram illustrating a main hardware configuration of the mobile terminal 100 of FIG.
The mobile terminal 100 includes a CPU (Central Processing Unit) 110 having a control function and an arithmetic function, a storage device 104, an operation device 118 that is an example of an input device, and a display device 116 that is an example of an output device. That is, the mobile terminal 100 has a computer.
The CPU 110 can exchange data and control codes with other components such as the storage device 104 via the bus 112. The CPU 110 controls the entire portable terminal 100 by reading and executing a program stored in the storage device 104.

The communication device 102 is, for example, a mobile phone unit, and has a function of modulating / decoding a signal from the base station 12 received by the communication antenna 102a, and converting a voice into a digital signal and placing it on a carrier wave. It has a function to transmit to.
The storage device 104 is configured by, for example, a RAM (Random Access Memory), and stores various programs and data such as an OS (Operating System) and a device driver.

The power supply device 106 is composed of, for example, a rechargeable lithium battery, and supplies power to each unit of the mobile terminal 10. Since the portable terminal is required to be small, the size of the battery is limited to a small one. Therefore, when the user frequently uses additional functions such as the GPS device 108 of the mobile terminal 100, the power supply device 106 can supply power only for about several hours.
The clock 107 is configured by a real time clock, for example, and the CPU 110 acquires the current time or the elapsed time from one time point to another time point based on a clock signal transmitted from the clock 107.

The GPS device 108, which is an example of the position calculation means, includes, for example, a circuit that converts a positioning signal received by the GPS antenna 108a that is a chip antenna into a baseband signal, a circuit that converts a received signal into a digital signal, and a correlation calculation. This is a GPS module in which a circuit for capturing GPS satellites, a circuit for decoding received signals and acquiring orbit information of GPS satellites, and the like are integrated on one chip.
Since the positioning terminal 100 does not perform positioning by the GPS device 108 indoors, the GPS device 108 is not highly sensitive and has normal sensitivity with a receiving sensitivity of about −130 dBm.

The display device 116 is composed of, for example, a liquid crystal display, and displays positioning results and the like as images so that the user of the mobile terminal 100 can visually recognize them.
The operation device 118 is used, for example, for a user of the mobile terminal 100 to move a plurality of buttons with characters on the surface used for inputting a telephone number and a cursor displayed on the display device 116. It consists of cursor movement buttons.

The short-range communication device 129, which is an example of the terminal-side wireless communication means, is a Bluetooth unit, for example, and has a communicable distance of about 10 m, but is a wireless communication device with low power consumption. The short-range communication device 129 can transmit and receive radio waves from the short-range communication antenna 129a to communicate with devices that implement a common communication protocol, for example, the short-range communication device 222 of the gates 200 and 201. it can.
The short-range communication device 129 is set to an operation mode in which a connection is passively established in response to a connection request from another device, for example, a discoverable mode in the case of Bluetooth.

(Main hardware configuration of gates 200 and 201)
FIG. 3 is a schematic diagram showing the main hardware configuration of the gates 200 and 201 of FIG. The description of the same components as the portable terminal 100 of FIG. 2 such as the CPU 210 will be omitted, and different parts will be described.

A short-range communication device 222, which is an example of a providing device-side wireless communication unit, is a wireless communication device that implements the same protocol as the short-range communication device 129 of the mobile terminal 100.
The short-range communication device 222 constantly transmits a connection request signal to another device, for example, the mobile terminal 100. Then, when the mobile terminal 100 enters the communicable range of the short-range communication device 222 and returns a response to the connection request signal, the connection between the two is established.
The power supply device 206 rectifies and transforms alternating current input from a commercial power line and supplies it to each part of the gates 200 and 201.

  FIG. 3 shows a self-supporting device having its own CPU 210 and storage device 104 as a configuration example of the gates 200 and 201, but it is configured as a peripheral device controlled by another computer via an input / output interface. You can also In that case, one computer may be configured to control a plurality of gates.

(Main software configuration of mobile terminal 100)
FIG. 4 is a schematic diagram illustrating a software configuration of the mobile terminal 100.
The control unit 130 has functions such as memory management, task management, and input / output management, and is a program for controlling the entire operation of the mobile terminal 100. Specifically, it is mounted on the OS stored in the storage device 104 and executed by the CPU 110.
The communication unit 162, the power supply unit 166, the clock unit 167, the GPS unit 168, the short-range communication unit 177, the display unit 176, and the operation unit 178 stored in the driver storage unit 160 are the communication device 102, the power supply device 106, and the clock, respectively. 107, a program for controlling the GPS device 108, the short-range communication device 222, the display device 116, and the operation device 118. These programs are implemented as device drivers, for example, and are physically stored in the storage device 104.

The CPU 110 sequentially reads and executes the programs stored in the program storage unit 140 under the control of the control unit 130. The CPU 110 reads and acquires data necessary for executing the program from the data storage unit 180. Further, data acquired by the control unit 130 and data generated by a program stored in the program storage unit 140 are also stored in the data storage unit 180.
Note that the three storage units illustrated in FIG. 4 do not indicate that the mobile terminal 100 includes three physically independent storage devices, and are stored in the storage device 104 for convenience of explanation. This information is to classify the information according to its type.

The positioning mode setting program 144, which is an example of the operation setting means, refers to the positioning mode flag 182 stored in the data storage unit 180 when the user of the portable terminal 100 passes through the gate 200 or 201, and its value Inverts the value to false if is true and true if it is false.
The positioning mode flag 182 is, for example, a logical variable indicating the operation state of the GPS device 108. When the value is true (T), the value of the GPS device 108 is permitted to be false (F). In this case, the operation of the GPS device 108 is prohibited.
That is, the positioning mode setting program 144 is a program for changing the operation setting according to the operation state of the GPS device 108.

  The building position information receiving program 145, which is an example of a building position information receiving unit, controls the short-range communication device 129 via the short-range communication unit 177 when the user of the mobile terminal 100 passes through the gate 200 or 201. The building position information 184 is received from the gate 200 or 201. Then, the received building position information 184 is stored in the data storage unit 180 (storage device 104) which is an example of the terminal-side building position information storage unit.

The building position information 184 includes the coordinates (latitude, longitude, altitude) of a representative location indicating the position of the building 16 (see FIG. 1), for example, the coordinates of the center position of the building 16, and the location where the gates 200 and 201 are installed. Coordinates etc. Therefore, the building position information 184 is different from the actual position of the mobile terminal 100, but the deviation from the actual position is at most about the size of one side of the building 16 (in many cases, at most several tens of meters) The accuracy is better than the coordinates obtained by positioning with the GPS device 108 indoors 22 (see FIG. 1). Depending on the purpose, this level of accuracy is often sufficient. For example, is the mobile terminal 100 located in the building 16 rather than the coordinate value itself, such as when the position of the mobile terminal 100 is used for attendance management? Sometimes it is important to know whether or not.
That is, it can be said that the building position information 184 has sufficient accuracy to be used as information indicating the position of the mobile terminal 100 while the mobile terminal 100 is in the building 16.
Unlike the GPS position information 186 described later, the building position information 184 does not include the acquired time information.

The location acquisition method selection program 146 is activated when a location information request is received from the location management server 300, for example.
The position acquisition method selection program 146 first refers to the positioning mode flag 182. When the value of the positioning mode flag 182 is true, position calculation by the GPS device 108 is selected as the position acquisition method, and the GPS positioning program 150 is activated. When the value of the positioning mode flag 182 is false, reading from the data storage unit 180 (storage device 104) is selected as the position acquisition method, and the transmission building position information generation program 147 is activated.

  The transmission building position information generation program 147 combines the time acquired from the clock 107 via the clock unit 167 and the building position information 184 read from the data storage unit 180 to generate transmission building position information 188, The data is stored in the data storage unit 180. In this way, the acquisition time is added to the building position information 184 because the position request program, for example, the position information providing program operating in the position management server 300, uses the format calculated by the GPS as the notified position information. This is because the data is assumed.

The GPS positioning program 150 is activated by the position acquisition method selection program 146 when there is a request for position information and the value of the positioning mode flag 182 is true. The GPS positioning program 150 issues a positioning start instruction to the GPS device 108 via the GPS unit 168. Then, the pseudo distance between the GPS satellite 10a (see FIG. 1) and the mobile terminal 100 based on the GPS satellite orbit information and the GPS time obtained by the GPS device 108 decoding the positioning signal S1 (see FIG. 1). And the position of the mobile terminal 100 is calculated based on the principle of triangulation.
The GPS positioning program 150 stores the calculated coordinates of the mobile terminal 100 and the GPS time as GPS position information 186 in the data storage unit 180.

A location information notification program 152, which is an example of a location notification means, notifies the location request program of the location of the mobile terminal 100. The program that requests the position information includes a program that is operating on a device other than the mobile terminal 100, for example, the positioning server 300, and a program that is operating on the mobile terminal 100.
The position information notification program 152 uses the GPS position information 186 when the value of the positioning mode flag 182 is true, and the transmission building position information 188 as the position of the mobile terminal 100 when the value of the positioning mode flag 182 is false. Notify the program that requested the location information.

(Main software configuration of the gates 200 and 201)
FIG. 5 is a schematic diagram showing a software configuration of the gate 200 and the gate 201.
The control unit 230 has functions such as memory management, task management, and input / output management, and is a program for controlling the entire operation of the gates 200 and 201. Specifically, it is mounted on the OS stored in the storage device 204 and executed by the CPU 210.
The power supply unit 266, the near field communication unit 269, the display unit 276, and the operation unit 278 stored in the driver storage unit 260 are for controlling the power supply device 206, the near field communication device 222, the display device 216, and the operation device 218, respectively. It is a program. These programs are implemented as device drivers, for example, and are physically stored in the storage device 204.

The building position information transmission program 242 which is an example of the building position information transmission unit controls the short-range communication device 222 via the short-range communication unit 269 when the mobile terminal 100 passes through the gate 200 or the gate 201, The building position information 284 is transmitted to the mobile terminal 100.
The building position information 284 is stored in advance in the storage device 204, which is an example of a providing device-side building position information storage unit, for example, when the operator operates the operation device 218.

(Operation example of positioning system 1)
Next, an operation example of the positioning system 1 will be described.
FIG. 6 is a flowchart illustrating the operation of the mobile terminal 100 when the user of the mobile terminal 100 passes through the gate 200. This operation is the same when passing through the gate 201.
When the user approaches the doorway 18, the connection request signal transmitted from the short-range communication device 222 of the gate 200 is received (ST10).
In response to the received connection request signal, the portable terminal 100 establishes a connection with the gate 200 from the gate 200 side (ST11, an example of a wireless connection establishment step).

When the connection with the gate 200 is established, the positioning mode setting program 144 refers to the positioning mode flag 182 and determines the subsequent operation based on the value (ST12).
When the value of the positioning mode flag 182 is true, that is, when the mobile terminal 100 is about to enter the building 16 through the doorway 18, the building position information receiving program 145 receives the building position information from the gate 200. (ST13, an example of a building position information receiving step), and stored in the data storage unit 180 (see FIG. 4) (ST14, an example of a terminal side building position information storing step). When the reception and storage of the building position information is completed, the positioning mode setting program 144 sets the value of the positioning mode flag 182 to false and prohibits the operation of the GPS device 108 (ST15, an example of an operation setting step).
When the value of the positioning mode flag 182 is false, that is, when the mobile terminal 100 is going out from the building 16 through the doorway 18, the positioning mode setting program 144 sets the value of the positioning mode flag 182 to true. Set and permit the operation of the GPS device 108 (ST16, an example of an operation setting step).

FIG. 7 is a flowchart showing the operation of the gate 200 when the user of the mobile terminal 100 passes through the gate 200. The operation of the gate 201 is the same.
The short-range communication device 222 of the gate 200 always transmits a connection request signal to other devices. When a response from the short-range communication device 129 of the mobile terminal 100 to the connection request is received (ST20), a connection with the mobile terminal 100 is established so that information can be transmitted and received (ST21).
When the connection with the mobile terminal 100 is established, the building location information 284 is transmitted to the mobile terminal 100 (ST22).

FIG. 8 is a flowchart showing the operation of the mobile terminal 100 when a location request is received from the location management server 300.
When the position request from the position management server is received (ST30), the position acquisition method selection program 146 is activated and refers to the positioning mode flag 182 (ST31).
When the value of the positioning mode flag 182 is true, the portable terminal 100 performs the operations from ST32 to ST35. The position acquisition method selection program 146 selects positioning by the GPS device 108 as a method for acquiring the position, and activates the GPS device 108 (ST32). The GPS device 108 captures GPS satellites and acquires orbit data of the GPS satellites from the positioning signals of the captured GPS satellites (ST33). The GPS positioning program 150 calculates the pseudo distance of the GPS satellite based on the data acquired by the GPS device, and calculates the position of the mobile terminal 100 and the GPS time (ST34) (ST32 to ST34 are examples of position calculation steps) ). The calculated position is stored in the data storage unit 180 as GPS position information 186. The position information notification program 152 transmits the GPS position information 186 as the position of the mobile terminal 100 to the position management server 300 (ST35, an example of a position notification step).
When the value of the positioning mode flag 182 is false, the mobile terminal 100 performs the operations from ST40 to ST43. The position acquisition method selection program 146 selects reading from the storage device 104 as a method for acquiring the position, and starts the transmission building position information generation program 147. The transmission building position information generation program 147 reads out the building position information 184 stored in the data storage unit 180 (ST40). Next, the building position information generation program for transmission 147 acquires the current time from the clock 107 of the mobile terminal 100 (ST41). The transmission building position information generation program 147 combines the building position information 184 and the current time to generate transmission building position information 188 and stores it in the data storage unit 180 (ST42). The position information notification program 152 transmits the building position information for transmission 188 to the position management server 300 as the position of the mobile terminal 100 (ST43, an example of a position notification step).

Next, as a specific operation example of the positioning system 1, an operation when the user of the portable terminal 100 (hereinafter referred to as “user” in this paragraph) moves along the arrow in FIG. 1 will be described.
It is assumed that the user is outdoors 20 at first. At this time, the value of the operation mode flag 184 of the mobile terminal 100 is true, and the operation of the GPS device 108 is permitted. At this time, for example, when there is a request for notification of position information from the position management server 300 to the mobile terminal 100, the mobile terminal 100 activates the GPS device 108 to calculate the position and notifies the position management server 300. .
Next, it is assumed that the user passes through the gate 200 installed at the entrance 18 and enters the indoor 22 of the building 16. When the user passes through the gate 200, the short-range communication device 222 of the gate 200 establishes a connection with the short-range communication device 129 of the mobile terminal 100 and transmits the building position information 284. The portable terminal 100 receives the building position information 284 and stores it in the data storage unit 180, and sets the value of the positioning mode flag 182 to false, thereby prohibiting the operation of the GPS device 108. For example, when there is a position information request from the position management server 300 while the user is indoors 22, the mobile terminal 100 does not perform positioning by the GPS device 108, but transmits the building position information 188 for transmission to the mobile terminal 100. The location management server 300 is notified of the location.
Next, it is assumed that the user passes through the gate 201 installed at the entrance 19 and exits the building 16. When the user passes through the gate 201, the near field communication device 222 of the gate 201 establishes a connection with the near field communication device 129 of the mobile terminal 100 and transmits the building position information 284. The portable terminal 100 receives the building position information 284 and stores it in the data storage unit 180, sets the value of the positioning mode flag 182 to true, and permits the operation of the GPS device 108. After the user leaves the building 16, for example, when there is a location information notification request from the location management server 300, the mobile terminal 100 activates the GPS device 108, calculates the location, and notifies the location management server 300. To do.

As described above, according to the mobile terminal 100 of the present embodiment, when the GPS device 108 is located in the indoor 22 where positioning by the GPS device 108 is difficult, the GPS device 108 can be used even if there is a location request from the location management server 300. Is not operated and the building location information for transmission 188 stored in the data storage unit 180 (storage device 104) is read and notified. Therefore, the position of the positioning terminal can be notified in response to the position request from the position management server 300 in a short time and with low power consumption.
In addition, since the wireless connection between the mobile terminal 100 and the gates 200 and 201 is established from the gates 200 and 201 side, the user of the mobile terminal 100 passes through the doorways 18 and 19 when the mobile terminal 100 passes. The operation state of the GPS device 108 can be automatically set and the building position information 184 can be acquired without any operation.

(Second Embodiment)
Next, the positioning system 1a which is the 2nd Embodiment of this invention is demonstrated. Since the configuration of the positioning system 1a has many parts that are the same as those of the positioning system 1, the same parts are denoted by the same reference numerals, description thereof is omitted, and different parts are mainly described.
FIG. 9 is a schematic diagram showing the positioning system 1a and the like. The positioning system 1a has basically the same configuration as the positioning system 1, and includes a mobile terminal 100a and gates 200a and 201a provided at the entrance of the building 16. When the portable terminal 100a passes the gate 200a or 201a, the basic operation of receiving the building position information from the gate and permitting or prohibiting the operation of the GPS device 108 is the same as that of the positioning system 1. However, the communication method between the portable terminal 100a and the gate 200a and the gate 201a and the storage method of the building position information received by the portable terminal 100a from the gate 200a or 201a are different from the positioning system 1.

  The portable terminal 100a has an RFID tag 120 and can communicate with the gate 200a and the gate 201a. When the mobile terminal 100 a enters the indoor 22 of the building 16 from the entrance 18, the mobile terminal 100 a acquires the building position information from the gate 200 a and stores it in the RFID tag 120. For example, when a location information transmission request is received from the location management server 300 indoors, the location information stored in the RFID tag 120 is notified to the management server 300 without performing positioning by the GPS device 108. To do.

  The gates 200a and 201a have an RFID tag reader / writer 214, and can read and write information by connecting to the RFID tag 120 of the portable terminal 100a by wireless communication. When the RFID 20 of the mobile terminal 100a transmits ID information in response to the connection request, the RFID reader / writer 214 transmits the building position information stored in the storage device of the gates 200a and 201a, and the RFID 120 Write to.

(Main hardware configuration of mobile terminal 100a)
FIG. 10 is a schematic diagram illustrating a main hardware configuration of the mobile terminal 100a of FIG. The mobile terminal 100a includes an RFID tag 120 and a voltage detection device 114 that the mobile terminal 100 (see FIG. 2) does not have. Further, since the RFID tag 120 performs communication with the gate 200a and the like, it does not have a short-range communication device.
Components other than the above, such as the communication device 102, are the same as those of the mobile terminal 100 of FIG.

  The RFID tag 120 is a passive type RFID tag, and converts the magnetic field or electromagnetic wave generated by the RFID tag reader / writer 214 of the gate 200a into electric power to obtain electric power necessary for the operation. The RFID tag 120 transmits ID information stored in the tag to the RFID tag reader / writer 214 in response to a connection request transmitted from the RFID reader / writer 214. In addition, the building location information transmitted from the RFID tag reader / writer 214 can be received and stored in the memory.

  The voltage detection device 114, which is an example of a tag activation detection unit, is connected to the outside of the RFID tag 120 so that the positioning mode setting program 144 (see FIG. 14) operating on the CPU 110 can know the activation of the RFID tag 120. An induced voltage output from the connection terminal 125 (see FIG. 11) is detected.

FIG. 11 is a schematic diagram showing the structure of the RFID tag 120.
The RFID tag 120 has a sealing body 126 made of, for example, a synthetic resin. This is a so-called inlet state in which an IC (Integrated Circuit) 121 and an antenna 124 are sealed in a sealing body 126. Normally, such an inlet processed into a card shape, for example, is used as an RFID tag. However, in this embodiment, since it is placed inside the mobile terminal 100a, it is used as an RFID tag in the inlet state. Yes.
An antenna 124 and an external connection terminal 125 are electrically connected to the IC 121.
The IC 121 includes a CPU 122 that controls the operation of the entire RFID tag 120 and a memory 123 that stores various types of information.
The CPU 122 has a function of controlling reading and writing of the memory 123 and communication with the RFID tag reader / writer.
Information such as an ID for identifying the RFID tag 120 is stored in the memory 123. In the portable terminal 100a, building position information acquired from the gate 200a or the like is also stored.
The antenna 124 is made of, for example, metal wiring, and is arranged in a spirally folded state in the sealing body 126 in order to secure a length necessary for transmitting and receiving signals.
The external connection terminal 125 is a terminal for electrically connecting to other circuits / devices. In the mobile terminal 100a, the voltage detection device 114 is used for detecting the induced voltage of the RFID tag 120, and for the CPU 110 reading the building position information stored in the memory 123.

FIG. 12 is a schematic diagram illustrating an example of information stored in the memory 123 of the RFID tag 120.
The building position information 123a is the same information as the building position information 184 (see FIG. 4) of the mobile terminal 100, and is a coordinate indicating the position of the building 16 acquired from the gate 200a or the like. That is, the memory 123 is an example of a terminal-side building position information storage unit.
The ID information 123b is information for identifying the RFID tag 120, and is, for example, a serial number that is a unique value for each tag.

(Main hardware configuration of the gates 200a and 201a)
FIG. 13 is a schematic diagram showing the main hardware configuration of the gates 200a and 201a of FIG. 3 is different from the gates 200 and 201 in FIG. 3 in that an RFID tag reader / writer 214 is provided instead of the short-range communication device 222 (see FIG. 3) as a device for communicating with the mobile terminal 100a. .

The RFID tag reader / writer 214 constantly transmits a connection request signal to an RFID tag that exists within a communicable distance around the gates 200a and 201a. When the user of the portable terminal 100a passes the gate 200a or the gate 201a, the RFID 120 transmits the ID information 123b in response to the connection request, and the RFID tag reader / writer 214 that receives the ID information 123b establishes a connection with the RFID 120. Let
When the connection is established, the RFID tag reader / writer 214 transmits the building position information 284 (see FIG. 12) stored in the storage device of the gate 200a or 201a to the RFID tag 120.

(Main software configuration of mobile terminal 100a)
FIG. 14 is a schematic diagram illustrating a software configuration of the mobile terminal 100a. Differences from the portable terminal 100 of FIG. 4 are as follows.
Since the mobile terminal 100 a has the RFID 120, the tag activation detection program 142 and the tag reading program 148 are stored in the program storage unit 140. Since the RFID tag 120 performs communication with the gate, the program for receiving the building position information from the gate (the building position information receiving program 145 in the portable terminal 100 in FIG. 4) is a program executed by the CPU 110. I don't have it. In addition, since the building position information received from the gate 200a or 201a is stored in the RFID tag 120, no building position information is stored in the data storage unit 180.
Since the portable terminal 100a has the voltage detection device 114, the voltage detection unit 174, which is a program for controlling the device, is stored in the driver storage unit 160.

  The tag activation detection program 142 accesses the voltage detection device 114 via the control unit 130 and the voltage detection unit 174, and acquires the induced voltage output from the RFID tag 120. Then, for example, when the acquired induced voltage is higher than a predetermined threshold value, it is determined that the RFID 120 has started, that is, the connection request from the gate 200a or 200b has been received, and the positioning mode setting program 144 is started.

The location acquisition method selection program 146a is activated when a location information request is received from the location management server 300, for example.
The position acquisition method selection program 146 first refers to the positioning mode flag 182. When the value of the positioning mode flag 182 is true, position calculation by the GPS device 108 is selected as the position acquisition method, and the GPS positioning program 150 is activated. When the value of the positioning mode flag 182 is false, reading from the RFID tag 120 is selected as the position acquisition method, and the tag reading program 148 is started.

  The tag reading program 148 is activated by the position acquisition method selection program 146 when there is a request for position information. The tag reading program 148 accesses the RFID tag 120 via the control unit 130 and reads the building position information 123 a stored in the memory 123. When the reading is completed, the tag reading program 148 activates the building position information generation program 147 for notification.

(Main software configuration of the gates 200a and 201a)
FIG. 15 is a schematic diagram showing a software configuration of the gates 200a and 201a.
5 is the same as the gates 200 and 201 in FIG. 5 except that a reader / writer unit 268 is stored in the driver storage unit 160 instead of the short-range communication unit 269 (see FIG. 5).

(About operation example of positioning system 1a)
Next, an operation example of the positioning system 1a will be described.
FIG. 16 is a flowchart showing the operation of the mobile terminal 100a when the user of the mobile terminal 100a passes through the gate 200a. This operation is the same when passing through the gate 201a.
When the portable terminal 100a approaches the doorway 18, the antenna 124 built in the RFID 120 can receive electromagnetic waves transmitted from the RFID tag reader / writer 214 of the gate 200a. Part of the electromagnetic wave received by the antenna 124 is converted into electric power by electromagnetic induction and supplied as operating electric power for the RFID tag 120 (ST10a).
The portable terminal 100a enters the communicable range of the RFID tag reader / writer 214 of the gate 200a, and waits until the induced voltage becomes a value sufficient to activate the RFID 120 (No in ST11a, ST10a).
When the portable terminal 100a enters the communicable range of the RFID tag reader / writer 214, the induced voltage becomes a value sufficient to activate the RFID 120, the RFID 120 is activated, and communication with the RFID tag reader / writer 214 is started (determination of ST11a). Yes, ST12).

When the RFID 120 is activated, the positioning mode setting program 144 refers to the positioning mode flag 182 and determines the subsequent operation based on the value (ST12).
When the value of the positioning mode flag 182 is true, that is, when the portable terminal 100a is about to enter the building 16 through the doorway 18, the RFID 120 receives the building position information from the RFID tag reader / writer 214 (DT13), The data is stored in the memory 123 of the RFID tag 120 (ST14). When the building position information is received and stored, the positioning mode setting program 144 sets the value of the positioning mode flag 182 to false (ST15).
If the value of the positioning mode flag 182 is false, that is, if the mobile terminal 100a is going to go out of the building 16 through the doorway 18, the positioning mode setting program 144 sets the value of the positioning mode flag 182 to true. (ST16).

FIG. 17 is a flowchart showing the operation of the gate 200a when the user of the portable terminal 100a passes through the gate 200a.
The RFID tag reader / writer 214 of the gate 200a constantly transmits a connection request signal. When a response from the RFID 120 of the portable terminal 100a to this connection request is received (ST20a), building location information is transmitted to the RFID 120 (ST21a).

  The operation of the mobile terminal 100a when receiving a positioning request from the location management server 300 is the same as that of the mobile terminal 100 shown in FIG. However, the acquisition destination of the building position information in ST40 is the memory 123 of the RFID 120.

Thus, since the terminal side wireless communication means of the portable terminal 100a is the RFID tag 120, the CPU 110 and the control unit 130 of the portable terminal 100a are not involved in communication between the gates 200a and 201a. That is, the CPU 110 of the mobile terminal 100a does not need to wait for a connection request from the gates 200a and 201a and operate a program for controlling communication after the connection is established. Therefore, the load on the CPU 110 is reduced and the power consumption can be reduced.
Further, since the received building position information is stored in the memory 123 in the RFID tag 120, it is not necessary to use the storage device 104 of the portable terminal 100a in order to store the building position information. Therefore, the storage device 104 can be used without waste.

(Third embodiment)
Next, the positioning system 1b which is the 3rd Embodiment of this invention is demonstrated. Since the configuration of the positioning system 1b has many parts that are the same as those of the positioning system 1a, the same parts are denoted by the same reference numerals, description thereof is omitted, and different parts are mainly described.
FIG. 18 is a schematic diagram showing the positioning system 1b and the like. The positioning system 1 b has basically the same configuration as the positioning system 1, and includes a mobile terminal 100 b and gates 200 b and 201 b provided at the entrance of the building 16. When the portable terminal 100b passes the gate 200b or 201b, the basic operation of receiving the building position information from the gate and permitting or prohibiting the operation of the GPS device 108 is the same as that of the positioning system 1a.
However, the positioning system 1b differs from the positioning system 1a in that the mobile terminal 100b has an RFID tag reader / writer 128 and the gates 200b and 201b have an RFID tag 220.

(Main hardware configuration of the mobile terminal 100b)
FIG. 19 is a schematic diagram illustrating a main hardware configuration of the mobile terminal 100b of FIG.
The RFID reader / writer 128 can read and write information by establishing a wireless communication connection with the RFID tag 220 of the gate 200b or 201b. The RFID tag reader / writer 214 reads building position information from the RFID tag 220 of the gate when passing through the gate 200b or 201b.

(Main hardware configuration of the gates 200b and 201b)
FIG. 20 is a schematic diagram showing the main hardware configuration of the gates 200b and 201b of FIG.
The structure of the RFID tag 220 and the stored information are the same as those of the RFID tag 120 shown in FIGS. However, unlike the portable terminal 100a in FIG. 11, the RFID tag 220 is not electrically connected to the CPU 210 and thus does not have an external connection terminal. The building position information 223a is input before the RFID tag 220 is attached to the gates 200b and 201b.
Since the RFID tag 220 can function alone as a building location information providing device, the CPU 210 is not involved in communication with the mobile terminal 100b. Therefore, the gates 200b and 201b do not need to be a computer system as shown in FIG. 20, but are structural members of the building 16 such as a reception counter installed near the doorway 18 or 19, or a pillar. May be.

(Main software configuration of mobile terminal 100b)
FIG. 21 is a schematic diagram illustrating a software configuration of the mobile terminal 100b.
The software configuration of the mobile terminal 100b is basically the same as that of the mobile terminal 100 shown in FIG.
The building position information receiving program 145b controls the RFID tag reader / writer 128 via the reader / writer unit 175, and receives building position information transmitted from the RFID 220 of the gates 200b and 201b.

(Main software configuration of the gates 200b and 201b)
FIG. 22 is a schematic diagram showing a main software configuration of the gates 200b and 201b.
In the present embodiment, since the program for communicating with the mobile terminal 100b and the building position information transmitted to the mobile terminal 100b are stored in the RFID tag 220, the gates 200b and 201b are computers such as the control unit 230 and the like. It has only basic components. By simply attaching the RFID tag 220 into which the building position information has already been input to the computer apparatus used for such other purposes, it can be used as a building position information providing apparatus.

(About operation example of positioning system 1b)
Next, an operation example of the positioning system 1b will be described.
FIG. 23 is a flowchart showing the operation of the mobile terminal 100b when the user of the mobile terminal 100b passes through the gate 200b. This operation is the same when passing through the gate 201b.
When the portable terminal 100b approaches the doorway 18, the connection request signal is transmitted to the RFID 220 of the gate 200b (ST10b). If there is no response to the connection request, transmission of the connection request signal is continued (No in ST11b, ST10b). If there is a response, the portable terminal 100b establishes a connection with the gate (Yes in ST11b, Yes, ST17).
The operations from ST12 to ST16 after the connection is established are the same as those of the mobile terminal 100 shown in FIG.

FIG. 24 is a flowchart showing the operation of the gate 200b when the user of the mobile terminal 100b passes through the gate 200b. The operation of the gate 201b is the same.
When receiving the connection request of the portable terminal 100, the RFID tag 220 of the gate 200b responds by transmitting ID information to the portable terminal (ST20b). The mobile terminal 100b receives this response, and a connection between the gate 200 and the mobile terminal 100 is established.
When the connection is established, the RFID tag 220 transmits the building location information 223a stored in the memory 223 to the mobile terminal 100b (ST22b).
The operation of the mobile terminal 100b when receiving a positioning request from the location management server 300 is the same as that of the mobile terminal 100 shown in FIG.

Thus, in the positioning system 1b, since the portable terminal 100b has the RFID tag reader / writer 128 for receiving the building position information, for example, in an existing computer system used for other purposes, By simply attaching the RFID tag 220 in which the building position information has been stored, the building position information providing apparatus can be obtained.
Therefore, according to the positioning system 1b of the present invention, the building position information providing apparatus can be configured easily and inexpensively.
