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.

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 includes a mobile terminal 100, an IC card 400, an entrance / exit management device 200, and an authentication server 500. The building 16 is a facility of the A company, and the employees of the A company always carry the portable terminal 100 and the IC card 400 serving as an identification card.
A mobile terminal 100 which is an example of a positioning terminal 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), a portable personal computer, and the like. .

The portable terminal 100 includes a communication device 102 (see FIG. 3), 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 received signal becomes weak because the positioning signal S1 or the like is blocked by the wall 26 or the ceiling (not shown), it takes a long time to calculate the position. Accuracy will also be lowered. 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 portable terminal 100 has an IC card reader 129 and can read building position information and the like recorded on the IC card 400. For example, when there is a high possibility that the mobile terminal 100 is located indoors 22 when a location information transmission request is received from the location management server 300, positioning by the GPS device 108 is not performed, and the IC card 400 is stored. The stored building position information is transmitted to the position management server 300.

  The IC card 400 carried by the user together with the portable terminal 100 has the IC 410 and stores ID information that is information for identifying the user in the memory 430 of the IC 410 (see FIG. 6). Further, when the user passes through the door 19a, the building location information and the entrance / exit information are written by the entrance / exit management device 200.

  One entrance / exit management device 200, which is an example of a building location information providing device, is disposed in the room 16a in the vicinity of the doors 19a, 19b, and 19c of the rooms 29a, 29b, and 29c of the building 16 and one outdoor unit. The entrance / exit management device 200 has an IC card reader / writer 222 and can read / write information from / to the IC card 400. The entrance / exit management device 200 includes a communication device 202 and can communicate with the authentication server 500 via a LAN (Local Area Network) 30.

As a general rule, only employees of Company A can enter the building 16. The corridor 27 of the building 16 is an unmanaged area 26 that can be freely accessed by employees of the A company. However, the rooms 29a, 29b, and 29c are, for example, research and development of new technologies. It is a management area 24 where only a specific person who is given the authority to enter the room can enter.
Therefore, a person who wants to enter each room has the ID information stored in the IC card 400 he / she carries with the room entrance / exit management apparatus 200 to be authenticated. The entrance / exit management device 200 makes an inquiry to the authentication server 500, and if the holder of the IC card 400 has the right to enter the room, the door 19a is unlocked and the room entry is permitted.
When the user ID is read, the building position information stored in the storage device and the entry / exit information IC card 400 indicating whether the current door passage is for entry or exit are written.

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.

The authentication server 500 is also a general server computer, has a communication device 502 (see FIG. 5), and can communicate with the entry / exit management device 200 via the LAN 30.
The authentication server 500 stores an employee database that records the authority to enter each room for each employee, and an entry / exit log that records the results of entry / exit.

  If there is a location request from the location management server 300 and the IC card 400 is available, the portable terminal 100 transmits the building location information written by the entrance / exit management device 200 to the location management server 300, Positioning with the GPS device 108 in the indoor 22 is avoided.

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 IC card reader 129 can transmit a connection request to the IC card by wireless communication and read information from the IC card that has responded. When the IC card 400 is within the communicable range and there is a response, the building position information and the entry / exit information stored in the memory 430 of the IC card 400 can be read.

At this time, there is no need to bring the IC card 400 into contact with the IC card reader / writer 222.
When the user of the portable terminal 100 has the right to enter the room 29a, the door 19a is unlocked, and the display device 216 displays, for example, “The right to enter the room has been confirmed. Please enter "and allow entry / exit. If you do not have authority to enter the room 29a, the door 19a is not unlocked, and the display device 216 displays, for example, "The entry authority could not be confirmed. You cannot enter (leave) this room. ”And do not allow entry.

The IC 410 includes a CPU 411 that controls the operation of the entire IC card 400 and a memory 430 that stores various types of information.
The CPU 411 has a function of controlling reading and writing of the memory 430 and communication with the IC card reader / writer. The memory 430 stores information such as user information for identifying the holder of the IC card 400.
The antenna 402 is made of, for example, metal wiring, and is arranged in a spirally folded state in the inlet 405 in order to secure a length necessary for transmitting and receiving signals.

FIG. 7 is a schematic diagram illustrating an example of information stored in the memory 430 of the IC card 400.
The building position information 430a is coordinates indicating the position of the building 16 written by the entrance / exit management device 200.
In the building position information 430a, 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 entrance / exit management device 200 are installed. The coordinates of the place. Therefore, the building position information 430a 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 application, this level of accuracy is often sufficient, and the mobile terminal 100 is located in the building rather than the coordinate value itself, for example, 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 430a 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 430a does not include acquired time information.

The entry / exit information 430b is information indicating whether the card holder's door 19a was entered or exited. For example, a character string “entering” is recorded in the case of entering a room, and a character string “exiting” is recorded in the case of leaving. This information is used by a position notification program 152 (see FIG. 8) of the portable terminal 100 described later to determine how to acquire position information notified to the position management server.
ID information 430c, which is an example of user identification information, is information for identifying the IC card 400, and is, for example, a serial number that is a unique value for each card.
That is, the memory 430 is an example of a card-side building position information storage unit and a user identification information storage unit.

(Main software configuration of mobile terminal 100)
FIG. 8 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 display unit 176, the operation unit 178, and the IC card reader unit 179 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 display device 116, the operation device 118, and the IC card reader 129. 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. 5 do not indicate that the mobile terminal 100 has 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.

An IC card search program 142, which is an example of IC card search means, is a program that searches whether there is an IC card that can be read by the IC card reader 129 around the portable terminal 100. The IC card search program 142 is activated by the position acquisition method selection program 146 when a position request is received from the position management server 300, for example, and transmits a connection request signal for the IC card. When there is a response from the IC card to this connection request signal, it is determined that there is a readable IC card.
The building position information reading program 144, which is an example of a building position information reading unit, controls the IC card reader 129 via the IC card reader unit 179 and reads information stored in the memory 430 of the IC card 400.

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 activates the IC card search program 142. When the IC card search program 142 can find a communicable IC card and the entry / exit information read from the IC card is “entrance”, the reading from the IC card is selected as the position acquisition method, and transmission is performed. The building position information generation program 147 is activated. When the IC card search program 142 cannot find a communicable IC card, and when the communicable IC card is found but the entry / exit information read from the IC card is “exit”, the position acquisition method The position calculation by the GPS device 108 is selected, and the GPS positioning program 150 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 read from the IC card 400 to generate the transmission building position information 188 and stores the data. Stored in the unit 180. As described above, the location request program, for example, the location information providing program operating in the location management server 300, adds the acquisition time to the building location information in the format calculated by the GPS as the notified location information. This is because data is assumed.

The GPS positioning program 150 is activated when there is a request for position information and the position acquisition method selection program selects positioning by the GPS device 108. The GPS positioning program 150 issues a positioning start instruction to the GPS device 108 via the GPS unit 168. The pseudo distance between the GPS satellite 10a (see FIG. 1) and the portable terminal 100 based on the orbit information of the GPS satellite and the GPS time acquired 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 for requesting position information includes a case where the program is operating on a device other than the mobile terminal 100, for example, the positioning server 300, and a case where the program is operating on the mobile terminal 100.
When the IC card search program 142 finds a communicable IC card and the entry / exit information is “entrance”, the location information notification program 152 displays the transmission building location information 188 and the IC card search program 142 If a communicable IC card could not be found, and if it was found but the entry / exit information is “leave”, the GPS location information 186 is notified to the program that requested the location information as the location of the mobile terminal 100 .

(Main software configuration of the entrance / exit management device 200)
FIG. 9 is a schematic diagram illustrating a software configuration of the entrance / exit management device 200.
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 entry / exit management device 200. Specifically, it is mounted on the OS stored in the storage device 204 and executed by the CPU 210.
The communication unit 262, power supply unit 266, key opening / closing unit 268, reader / writer unit 269, display unit 276, and operation unit 278 stored in the driver storage unit 260 are the communication device 202, power supply device 206, and key opening / closing device 208, respectively. , A program for controlling the IC card reader / writer 222, the display device 216, and the operation device 218. These programs are implemented as device drivers, for example, and are physically stored in the storage device 204.

The building position information writing program 242 which is an example of the building information writing means brings the IC card 400 close to the IC card reader / writer 222 of the entrance / exit management device 200 so that the user of the portable terminal 100 can pass through the door 19a. Sometimes, the IC card reader / writer 222 is controlled via the reader / writer unit 269 to write the building position information 284 to the IC card 400.
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.

The authentication inquiry program 244 passes through the reader / writer unit 269 when the user of the portable terminal 100 brings the IC card 400 close to the IC card reader / writer 222 of the entry / exit management device 200 so as to pass through the door 19a. The IC card reader / writer 222 is controlled to read the ID information 430c from the IC card 400. Next, the ID information 430c and the device identification information 286 are transferred to the authentication server 500 via the communication device 202 and the LAN 30, and the authentication result transmitted from the authentication server 500 is received. That is, it is an example of a user identification information reading unit and an example of a user identification information transmission unit.
The device identification information 286 is a serial number unique to each building position information providing device 200, for example.

  A key opening / closing program 246, which is an example of an entry / exit restriction means, opens / closes the key of the door 19a based on the authentication result information received from the authentication server 500 by the authentication inquiry program 244. When the holder of the IC card 400 has the authority to enter the room, the door 19a is unlocked. When the owner of the IC card 400 does not have the authority to enter the room, the door 19a is locked.

(Main software configuration of authentication server 500)
FIG. 10 is a schematic diagram illustrating a software configuration of the authentication server 500.
The authentication server 500 is a general server computer and includes a control unit 530 including an OS and a database management program. Further, a device driver group for controlling each hardware shown in FIG. 5 is stored in the driver storage unit 560.

  The user database 582, which is an example of a regular user database, includes, for example, one record of all the valid users of the positioning system 1 with the ID information, name, and presence / absence of entry rights to each room. It is a recorded database. The user database 582 is stored as a file in the external storage device 505, and is loaded into the data storage unit 580 (physically the storage device 504) by the control unit 530 and used as necessary.

  The entrance / exit log 584 is a database that records the result of the authentication process performed by the entrance / exit authentication program 542, and is used, for example, to investigate the cause when there is an information leak accident. Each time the authentication process is performed, for example, the ID information of the IC card, the owner's name, the room identification number, the authentication result (permitted or denied), and the processing time are added as one record. The entrance / exit log 584 is also stored as a file in the external storage device 580.

  The device database 584 is a database that associates the device identification information of each building position information providing device 200 with the installed location. The entrance / exit authentication program 542 searches the device database using the device identification information received from the building location information providing device as a key, and acquires the installation location of the building location information providing device 200 that transmitted the device identification information.

The entrance / exit authentication program 542 performs the entrance / exit authentication process of the room 29a based on the ID information transmitted from the entrance / exit management device 200 and the room identification number, and generates authentication result information 588. The authentication result information 588 includes, for example, a regular user flag 588a indicating whether the IC card holder is a regular user, and an entrance / exit authority indicating whether the IC card holder has the entry / exit authority. Flag 588b.
The entrance / exit authentication program 542 receives the ID information transmitted from the entrance / exit management device 200 and searches for a record in which the ID information field matches the received ID information. If a matching record is found, the IC card holder is determined to be a regular user, and the value of the regular user flag 588 is set to true (T). Next, referring to the entry authority field, if the IC card holder has entry / exit authority to the room 29a, the value of the entry / exit authority flag 588b is set to true.
If a matching record is found, it is determined that the IC card holder is not a regular user, and the values of the regular user flag 588 and the entry / exit authority flag 588b are set to false (F). Next, referring to the entry authority field, if the IC card holder has entry / exit authority to the room 29a, the value of the entry / exit authority flag 588b is set to true.
The entrance / exit authentication program 542 transmits authentication result information 588 to the entrance / exit management device 200 via the communication device 502 and the LAN 30, and records the result of the authentication process in the entrance / exit log 584. That is, the entrance / exit authentication program 542 is an example of a user identification information receiving unit and an entrance / exit authentication processing unit.

(Operation example of positioning system 1)
Next, an operation example of the positioning system 1 will be described.
FIG. 11 shows the operation of the entry / exit management device 200 when the user of the portable terminal 100 brings the IC card 400 close to the IC card reader / writer 222 of the entry / exit management device 200 in order to pass through the door 19a and the like. It is a flowchart.
First, the ID information 430c is read from the IC card 400 (ST10).
The ID information 430c read from the IC card and the device identification information 286 stored in the storage device 202 are transmitted to the authentication server 500 (ST11).
The authentication result information 588 is received from the authentication server 500, and it is confirmed whether or not the ID information 430c transmitted in ST10 belongs to the authorized user of the positioning system 1 (ST12). When the value of the regular user flag 588a included in the authentication result information 588 is false, the entrance / exit is rejected without unlocking the door (No in ST12, ST12).
When the value of the regular user flag 588a is true, the building position information 284 is read from the storage device 204 and written into the memory 430 of the IC card 400 (Yes in ST12, Yes, ST13). By writing the building position information at this stage, even if entry / exit is denied in the subsequent steps, the mobile terminal 100 uses the building position information 430a written in the IC card 400 when a positioning request is made. Will be able to.
When the building location information and the like have been written, it is determined whether the holder of the IC card 400 has the right to enter and leave the room 29a (ST15). When the value of the entrance / exit authority flag 588b included in the authentication result information 588 is false, the entrance / exit is rejected without unlocking the door (No in ST14, ST21).
When the value of the entry / exit authority flag 588b is true, it is determined whether the current passage of the door 19a is for entry or exit. If it is for entering the room, “entrance” is written in the IC card 400 as the entry / exit information 430b and transmitted to the authentication server 500 (Yes in ST15, Yes, ST36 and ST37). If it is for leaving the room, “leaving” is written in the IC card 400 as the entry / exit information 430b and transmitted to the authentication server 500 (No in ST15, ST19 and ST20).
If the holder of the IC card 400 has the authority to enter and leave the room 29a, the door 19a is unlocked in both cases of entering and leaving, and entry / exit is permitted (ST38).

FIG. 12 is a flowchart showing the operation of the mobile terminal 100 when there is a location request from the location request program.
When a position request from the position request program is received (ST30), the IC card search program 142 is activated to check whether there is a communicable IC card in the vicinity (ST31, an example of an IC card search step).
If there is no communicable IC card (No in ST32), the position is calculated by the GPS device 108 and the GPS positioning program 150 (ST40, an example of a position calculation step) and notified to the position request program (ST41, An example of a position notification step).
Even when a communicable IC card is found, the IC card may not be that of the user of the mobile terminal 100, so a confirmation process is performed. The portable terminal 100 compares the ID information read from the communicable IC card with the ID information stored in the storage device 104, and if the two match, the communicable IC card is the one of the portable terminal 100. It is determined that it is the user's own (determination of ST32 is Yes, ST33).
When the communicable IC card is not that of the user of the portable terminal 100 (No in ST34), the position is calculated by the GPS device 108 and the GPS positioning program 150 (ST40), and the position request program is notified ( ST41).
If the communicable IC card is that of the user of the portable terminal 100 (Yes in ST34), the building position information reading program 144 and the IC card reader 129 are used to read the building position information 430a from the IC card 400. Then, the entrance / exit information 430b is read (ST35, an example of a reading step of building position information, etc.) However, the building position information 430a and the entry / exit information 430b may not be held due to reasons such as failure of writing by the entry / exit management device 200, and in this case, reading fails.
When the read / exit information is “leaving” (NO in ST36), the user of the mobile terminal 100 is in the outdoor 22 or the corridor 27. However, since the corridor 27 does not usually stay for a long time, it can be said that the user is likely to be outdoors. Therefore, the position is calculated by the GPS device 108 and the GPS positioning program 150 (ST40) and notified to the position request program (ST41).
If the read entry / exit information is “entrance” (Yes in ST36), it is certain that the user of the mobile terminal 100 is in one of the rooms 29a, 29b, and 29c. However, if the building position information is not recorded on the IC card 400 (No in ST37), the position is unavoidably calculated by the GPS device 108 and the GPS positioning program 150 (ST40), and the position request program Notification (ST41) is made.
When building position information is recorded on the IC card 400 (Yes in ST37), the building position information for transmission 188 is read from the storage device 202 and notified to the position request program (ST38).

FIG. 13 is a flowchart showing the operation of the IC card 400 when the user passes through the door 19a.
When IC card 400 approaches IC card reader / writer 222 of entry / exit management device 200, ID information is transmitted in response to a connection request from IC card reader / writer 222 (ST50). The entrance / exit management device 200 transmits the ID information to the authentication server 500 to perform an authentication inquiry process.
When the authentication result information indicates that the holder of the IC card 400 is an authorized user, the building location information and the entrance / exit information are received from the entrance / exit management device 200 and stored in the memory 430 (ST51).

FIG. 14 is a flowchart showing the operation of the IC card 400 when the portable terminal 100 receives a request from the position request program.
In response to the connection request from the IC card reader 219 of the portable terminal 100, ID information is transmitted (ST60). The portable terminal 100 collates the received ID information with the ID information stored in the storage device 104 and confirms whether the responding IC card belongs to the user of the portable terminal 100.
When the confirmation of the ID information is completed and there is a connection request again from the portable terminal 100, the building location information 430a and the entrance / exit information 430b are read from the memory 430 and transmitted to the portable terminal 100 (ST61).

Up to this point, the configuration and operation of the positioning system 1 have been described on the assumption that the IC card 400 is physically independent of the mobile terminal 100. However, as in the present embodiment, the contactless IC card and the corresponding operation are supported. When the IC card reader / writer is used, the IC card 400 can be integrated with the portable terminal 100, for example, the IC card can be arranged inside the portable terminal housing. In this case, the inlet 405 from which the card base 406 is removed from the IC card 400 of FIG. 6 is attached to the portable terminal.
In this way, there is an advantage that the user of the positioning system 1 is freed from the trouble of always carrying two devices.

Thus, according to the positioning system 1 of the present invention, when there is a high possibility that the mobile terminal 100 is located indoors where positioning by the GPS device 108 is difficult, there is a position request from the position request program. However, the GPS device 108 is not operated, and the building position information 430c is read from the IC card 400 and notified. Therefore, the position of the portable terminal 100 can be notified in response to a position request from the position request program in a short time and with low power consumption.
Furthermore, since the positioning system 1 also has a function as an entrance / exit management system, it is possible to identify an authorized user of the positioning system 1 and provide building position information only to the authorized user.
If an entrance / exit management system has already been constructed, building location information storage means and building location information writing means are added to the entrance / exit management device installed in the door 19a of the room 29a. The building location information providing apparatus can be easily configured only by this.
Further, since the IC card 400 is a non-contact type, the IC card 400 can be attached to the portable terminal 100 and integrated. Further, the operation for reading and writing the IC card 400 is simple, and the user can pass through the door 19a and the like of the room 29a and the like more smoothly.

(Second Embodiment)
Next, the positioning system 1a which is the 2nd Embodiment of this invention is demonstrated. Since there are 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.
The configuration and operation of the positioning system 1a shown in FIG. 1 are basically the same as those of the positioning system 1. However, the IC card 400a is a contact type, and the IC card reader / writer 222a of the entrance / exit management device 200a is compatible with a non-contact type IC card.

FIG. 15 is a schematic diagram showing the appearance of the entrance / exit management device 200a.
The entrance / exit management device 200 a includes a substantially rectangular parallelepiped housing 201, and a display device 216 and an operation device 218 are provided on the upper surface 202. As can be seen from the entrance / exit management device 200 of FIG. 2 and the entrance / exit management device 200a of FIG. 15 by looking at the relative size of the IC card 400 or 400a, the entrance / exit management device 200a Compared to 200, the size can be reduced.
The housing 201 is provided with a slot 205 for inserting the IC card 400a. When the user of the portable terminal 100 passes through the door 19a, the user inserts the IC card 400a through the slot opening 203 provided on the front surface of the casing, and reads the ID information.
An IC card reader / writer 222a is disposed inside the housing 201 below the slot 205. The input / output terminals of the IC card reader / writer 222a are in contact with and electrically connected to the respective terminals of the IC 410a of the IC card 400a, and can read and write information to and from the memory 430.
Since the IC card reader / writer 222a does not need to perform wireless communication with the IC card 400a, the IC card reader / writer 222a can have a simpler configuration than the IC card reader / writer 222 of FIG.

FIG. 16 is a schematic diagram showing the structure of the IC card 400a.
The IC card 400a has a card base 406 made of, for example, a synthetic resin, and the IC 410a is embedded therein. The terminals of the IC 410 (see FIG. 17) are exposed on the surface of the card base 406. Since the IC card 400a exchanges signals in contact with the reader / writer, the IC card 400a does not have an antenna for performing wireless communication.
Thus, the IC card 400a has a simpler configuration than the non-contact type IC card 400.

FIG. 17 is a schematic diagram showing the structure of the IC 410a. The IC 410a is a circuit in which a power source 412, a reset 413, a clock 414, a spare 415, an installation 416, a program supply voltage 417, a data input / output 418 are arranged, a terminal layer 422, a CPU 411, and a memory 430 are arranged. The layer 420 has a two-layer structure.
Each terminal such as the power supply 412 is in contact with a terminal of the IC card reader / writer 222a, and can receive supply of operating power or exchange information.

  Thus, according to the positioning system 1a of this embodiment, since the entrance / exit management device 200a and the IC card 400a can be configured simply, a positioning system can be constructed at a lower cost than the positioning system 1. Can do.

(Programs and computer-readable recording media)
A positioning terminal control program for causing a computer to execute the building position information reading step and the like of the above-described operation example can be provided.
Moreover, it can also be set as the computer-readable recording medium which recorded the control program of such a positioning terminal.

  A program storage medium used for installing these positioning programs and the like in a computer and making them executable by the computer is, for example, a floppy disk such as a floppy (registered trademark), a CD-ROM (Compact Disc Read Only Memory), Not only package media such as CD-R (Compact Disc-Recordable), CD-RW (Compact Disc-Rewritable), DVD (Digital Versatile Disc), etc., but also semiconductor memories and magnetic disks in which programs are temporarily or permanently stored Alternatively, it can be realized by a magneto-optical disk or the like.
