[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for providing useful information to a user who owns a portable device by using a plurality of information communication devices installed in a specific area.

[0002]

2. Description of the Related Art In recent years, a device that detects the position of one's own and displays the detected position information on a map to assist the user in reaching a destination is rapidly spreading. In particular, what has been developed as a vehicle device is the center of development of this type of device. On the other hand, a device that can be carried by a person, for example, a GPS (Global Positioning System) receiver detects latitude and longitude information of the current position of the user, and compares the detected information with map information printed on paper or the like. Thus, a device having a simple structure for assisting in arriving at the destination by performing the indexing work of the present location is being realized.

[0003] These devices are highly public systems on the assumption that they can be used on commonly available roads and on public places. For this reason, confining it to a specific area with low publicity,
It can be said that a system that positively provides effective service information to those who enter the area and use facilities and the like existing in the area is not considered so much.

As described above, as a system for limiting information to a specific area, providing information suitable for the area, and assisting in confirming the location of oneself in the specific area, for example, Japanese Patent Laid-Open No. 7-46176 and JP-A 7-569
There is a technique disclosed in Japanese Patent No. 91. That is, according to the former publication, a wireless device mounted on a moving vehicle or the like is provided with a direction detecting means for detecting a direction in which the vehicle is traveling and a means for collating the detected direction with the direction in which the transmitting station exists. There has been proposed a system for communicating a correct route to a destination, specifically, information on a right turn, a left turn direction, etc. Further, according to the latter publication, a device for transmitting information including an identification ID for identifying the user for the purpose of detecting the location of the user is carried by the user, and the device is installed in a ground station installed on the ground. , This identification ID is detected, the location of the user is grasped, inquiries from other users are provided with the grasped location information, and the employee who performs the system operation business is also notified, It is intended to provide a system capable of easily dealing with a lost child or the like.

Further, in this system, the technical disclosure is also made for the user to confirm the position of himself / herself and to combine it with the navigation function by using the portable device. Also, the system specializes in monitoring the position of a moving person, and
A system in which a control device provided in the ground station monitors the number, the position information of the ground station that received the ID transmitted by the mobile device, and the reception time information, and finds a person who moves the mobile device is disclosed in Japanese Patent Application Laid-Open It is disclosed in Japanese Patent Laid-Open No. 3-6929 and Japanese Patent Laid-Open No. 5-199168.

Further, as a system for providing a service for providing information to a user carrying a portable device within a specific area, in addition to checking the position of a person and finding a person, Japanese Patent Laid-Open No. 222126/1992. There are systems disclosed in the official gazette and Japanese Patent Laid-Open No. 5-300073. That is, the one described in the former publication receives the information of the destination from the portable device,
A system that provides a guide route to the destination, and the system described in the latter publication is a system that provides information to a queue at a facility such as an amusement park, that is, to wait for using the facility at the amusement park. It is a system that has a function to notify the portable device of the person making the line how much time is left before the facility can be used.

[0007]

In the prior art as described above, for example, in a specific area such as guidance to a place where a specific facility exists or search support for group members who have been separated. Although it is a system that provides information to users, it is not a system that provides useful information to users who are going to use a plurality of facilities installed in a specific area. That is, as a factor that determines a person's behavior, in addition to static information that is information that does not change for a predetermined time or longer, dynamic information that changes within a predetermined time is also an important factor that determines a behavior.
That is, not only static information such as where a certain facility is located in a specific area, but also, for example, the time-varying dynamics such as the length of a queue of users at a certain facility, etc. It is an empirical fact to judge the target information and to consider the usage of the facility. However, a system that can obtain such dynamic information in a plurality of communication areas within a specific area has not been proposed, and various conventional information communication systems will use a plurality of facilities within the specific area. There is a problem that it is not convenient for those who want to.

[0008] For example, as a system for providing dynamic information, a system for registering a turn and allowing the portable device to warn when it is his turn, or allowing the user to enter the facility by showing the portable device, etc. However, it is not considered to actively provide dynamic information in the area, and there is a problem that it is not convenient for users of multiple facilities in the specific area. there were.

[0009] In addition, although it has been proposed that the business operator of each facility provides information on the facility operated by the company to guide the user, even if the information provided by a specific business operator can be grasped, It is not a system that can accept information provided by other companies and comprehensively judge these.

Further, no simple and inexpensive means for ascertaining where the user who owns the portable device currently exists in the specific area has not been proposed. If a GPS system or the like is used, the system cost will be reduced. The rise is a problem.

As described above, according to the conventional system, even if it is possible to provide route guidance to the destination, the user can immediately reach the entrance to the intended facility due to lack of provision of dynamic information. There is not enough information to decide whether it is best to go, and the information necessary for the user to take action has not been provided enough, and the convenience for the user has decreased significantly. .

The object of the present invention is to solve these problems,
By multiple information communication devices installed in a specific area,
It is to provide a system that provides useful information to a user who owns a mobile device.

Such information transmitted and received between the respective devices is static / dynamic information for other facilities, which is stored in the storage means provided in the other ground communication device, and which is received or otherwise. The static / dynamic information about the facility is stored in the storage means of the own device, and the portable device 4 existing in a predetermined communication area 7 for the own device is transmitted via the wireless base communication device 2. It is receivable and sent periodically.

As described above, one feature of the present invention is that the dynamic / static information of not only the own device but also other terrestrial communication devices is periodically transmitted within the communication area of the own device. is there.

Note that, as the information that the wireless base communication device 2 periodically transmits, there is also an identifier (device ID) defined uniquely to the device.

The dynamic information is information that changes at a predetermined time interval, that is, it changes momentarily, and the static information is information that does not change at a predetermined time interval. Specific examples of these will be described later.

Next, with reference to FIG. 2, a mode in which the user obtains the portable device 4 used in the specific area 6 will be described. The portable device 4 is normally manufactured as a device that can be used only within the specific area 6 because it is advantageous in cost if it is manufactured as a dedicated terminal with limited functions. Visitors 8
On the other hand, it is a general rule that a business operator operating various facilities in the specific area 7 lends the portable device 4 and returns it when the portable device 4 is left. That is, the visitor 8 from the entrance 9 receives the service counter 10
In general, the system adopts the rules of "a) exchange the security deposit, b) lend the mobile device", and "c) return the mobile device the d) the security deposit when returning the mobile device." . Further, the user may adopt a rule of purchasing the portable device 4, and if the portable device 4 is combined with a general radio, a receiver for receiving a television broadcast, a game machine, an electronic notebook, a personal computer, etc. It can be used outside area 6. It is also preferable to purchase the portable device 4 at a store 11 existing inside or outside the area.

For the purchaser 8'outside the area, the profit received from this system is after the entrance to the specific area 6. In areas other than the specific area 6, the use is limited to general radio and television broadcast receivers. In addition, even if the portable device 4 with special specifications only for this system is left as it is, the specifications can be unified for a plurality of specific areas 6 or necessary geographical information can be easily set for each specific area 6 (for example, a plurality of It is possible to use the same mobile device 4 in other specific areas 6 as well, so that multiple types of IC memory cards that store different types of map information can be attached and removed. If the user purchases, he / she can save the trouble of borrowing, and can enjoy the profit of the purchase.

In any of the modes, the visitor 8 having the portable device 4 can receive the information sent from the wireless base communication device 2 and grasps the situation in each facility based on the received information. be able to. Such information may be used according to the interests and purposes of each individual, and a system for the convenience of the user can be constructed.

FIG. 3 is an explanatory diagram for explaining how the system described with reference to FIGS. 1 and 2 is operated. For facilitating understanding, reference numerals “8” and “4” indicating visitors and portable devices are attached to the reference numerals “8” and “4” as representatives. In addition, the facility in the present system may be a sale venue, an event venue, various goods sales floors, a permanent attraction venue, or the like, and the facility may be of any type and may be used for operation.

In FIG. 3, the terrestrial radio base communication device 2 is
As shown in the figure, it is installed near the entrance of special sale, event venue, etc., and above the entrance 9 to the specific area 6,
As an example, the directivity of the antenna is adjusted so that a range having a radius of about 10 (m) with the wireless base communication device 2 as the center constitutes one communication area 7. The wireless base controllers 1 (not shown) are connected to each other, acquire static and dynamic information of other facilities, and the acquired information is transmitted via the wireless base communication device 2.

In the example shown in FIG. 3, a range of about 10 (m) in radius with the wireless base communication device 2 as the center is 1
The directivity of the antenna and the like are adjusted so as to form one communication area 7. However, it is possible to set the size of this communication area 7 depending on the size of the venue, but if you look around the center around a certain facility, the visitor can confirm the correct current position. It is sufficient to set the communication area 7 to a sufficient extent.

The setting of the communication area 7 also depends on the shape of the specific area 6, but when the specific area 6 has a complicated shape, the communication area 7 is narrowed and the wireless base communication device 2 operates. In areas where the number is increasing, there are no obstacles, and radio waves can reach far, the communication area 7
Even if is relatively wide, there is no problem in confirming the position.

As described above, it is possible to arrange a plurality of terrestrial communication devices for one facility.

The communication areas 7 of the wireless base communication devices 2 are set so as not to overlap each other. In order to guarantee continuity of communication, the communication areas of ordinary mobile phones are intentionally overlapped, but in this system, on the contrary, the communication areas do not overlap each other. By setting to, the position detecting function of the portable device 4 is realized with a simple configuration.

FIG. 4 is a block diagram showing the hardware structure of the terrestrial communication device 20 and the portable device 4 which constitute the system shown in FIG.

The terrestrial communication device comprises a wireless base controller 1 for transmitting information wirelessly, a wireless base communication device 2, and a static / dynamic information input device 3. . Further, the wireless base controller 1 includes an I / O control unit 24 that exchanges information with other devices,
A memory 2 that stores a device-specific identification ID and programs
2, a code conversion unit 23 that converts static and dynamic information and the like into a predetermined communication format, a control unit 29 that performs display control of a display unit (not shown), and a CPU that controls each component. Configured to have. The display is static /
It is preferable to have a function of displaying information input via the dynamic information input device 3. In addition, if an external memory or the like is required, the connection is made so that the operation is controlled by the control unit 29.

Further, the radio base communication device 2 has a modulator 25 for modulating a signal to be transmitted, a transmitter 26 for actually outputting a radio signal, and a transmission controller 27 for controlling transmission. To be done.

In FIG. 4, each information indicated by reference numeral 21 is
3 shows an example of information transmitted by the ground communication device 20.
If each facility in the specific area 6 has dynamic information at that time, such as waiting time information, reservation status, as shown in the figure,
It is easy to imagine that if the congestion situation is known in advance before going to each facility, it will be useful information for users to decide their actions, if they understand static information in the venue to some extent in advance. . That is, each piece of information indicated by 21 is output from the transmission unit 26 of the own device, and the bus and I / O control unit 2
By being sent to another terrestrial communication device via 4 and also transmitted from the transmitting unit included in the other terrestrial communication device, the user can obtain information about each facility in the specific area 6, and the user can It becomes possible to plan the convenience of.

For users who have not obtained sufficient facility information, information on permanent events (permanent event information), specific information on a date / time basis that is event information that changes by day or time, and future It is also useful to provide static information such as advance notice information about events, etc. and information on specific events that are regularly held.

Also, if a notice or the like can be known promptly, it will be useful information for a user who repeatedly visits the specific area. As described above, the static / dynamic information as indicated by 21 can be input by the static / dynamic information input device 3 included in the ground communication device 20. Needless to say, the information that can be input is not limited to the illustrated information.

Information input via the static / dynamic information input device 3 is sent to the wireless base controller 1.

The wireless base controller 1 mainly executes processing of data to be transmitted. For example, information processing is performed so that the data becomes data according to a predetermined wireless transmission data format. It also manages the state of the wireless base communication device 2 and the state of the static / dynamic information input device 3. Here, as the state management, for example, failure detection can be mentioned.

Further, in the specific area 6, a process for exchanging information with another ground-side device 20 installed at another place is also performed, and information is exchanged using the I / O control unit 24. Also controls. In this way, the storage information of its own device and the information received from the other device are combined and output to the wireless base communication device 2.

The control unit 27 of the wireless base communication device 2 controls transmission, more specifically, adjusts the directivity of transmitted wireless data and the transmission output power. By adjusting the transmission power and directivity, the communication area is adapted to the shape of the specific area, and it is not necessary to prepare an extra wireless base communication device 2. The wireless data that has undergone such transmission control is transmitted via an antenna that constitutes the transmission unit 26.
Sent.

Next, the portable device 4 will be described.

The portable device 4 operates the antenna 30 for receiving a radio signal, the portable device controller 32 for controlling the portable device, the display device 37 for displaying necessary information, and the portable device 4. And an audio output device 39 for outputting information by audio. Further, the portable device control device 32 has a display controller 36 that controls the display device 37, an I / O control device 35 that operates as an interface between the operating device 38, the voice output device 39, and the portable device control device 32, and a map. A memory 34 that operates as a storage area or work area for information and programs, and a wireless base ID number that stores a list of identification numbers (ID numbers) unique to the terrestrial communication device that the terrestrial communication device periodically transmits. The determination device 5 includes a determination device 5, a demodulation device 31 that demodulates wireless information obtained via an antenna, and a main control processor 33 that controls the operation of each component.

The operation of the portable device 4 will be described below.

First, the radio data received via the antenna 30 is demodulated by the demodulation device 31, and the main control processor 33 performs a predetermined process based on the demodulated information.

The predetermined processing performed by the main control processor 33 is performed according to a program previously stored in the memory 34. The data processed by the main control processor 33 is output so that the user can grasp it.
The data to be temporarily stored in the memory 34 and to be displayed is displayed and output to the display device 37 via the display controller 36. The memory 34 can usually be realized by a semiconductor memory or the like, but it is also preferable that it be realized by a memory card or the like.
Geographical information within a specific area is recorded in the memory card, for example. Of course, it goes without saying that a storage medium such as a floppy disk may be used instead of such a memory card.

On the other hand, the data to be output as voice is output from the voice output device 39 including a speaker and the like via the I / O control device 35. These processes are automatically performed by the main control processor 33 according to the mode set by the user by operating the operating device 38. The setting operation performed by the user includes, for example, determination of an output mode of voice output and / or display output, input of various commands such as a command to display position information, and the like.

To grasp the current location, the wireless base ID number determination device 5 also refers to the data stored by itself based on the geographical information stored in the memory 34 and the received ID number of the ground communication device 20. And ask. That is, the wireless base ID number determination device 5 determines from which terrestrial communication device 20 the received ID number is, and sets the existing position of the terrestrial communication device 20 as the current position. Since the existing position of the ground communication device 20 is described in advance on the map, it may be displayed with a cursor or the like with the position as the current position. It should be noted that the position of the facility corresponding to the ground communication device 20 may be displayed as the current position, and this is more common from the standpoint of facility utilization. With such a method of grasping and displaying the current position, it is not possible to track the position information that changes every moment like the GPS system, and for example, the position information is tracked on a facility basis. However, sufficient information can be obtained with a simple and inexpensive configuration.

The wireless base ID number judging device 5 may be constructed by special hardware as shown in the figure,
It may be realized by software processing performed by the main control processor 33, but if the main control processor 33 has sufficient processing capacity, it is economical to perform it by software processing.

Now, suppose that the information to be transmitted from the terrestrial communication device 20 side to the portable unit 4 is "downlink information", and some of the specific examples shown as information 21 in FIG. 4 are shown in FIG. Shown in. As described in the description with reference to FIG. 4, the downlink information is roughly classified into dynamic information and static information. The dynamic information is information that changes within a predetermined time, and is information that changes momentarily within the facility. The static information is information that does not change within a predetermined time, and is set as various information that the operator of the specific area has planned in advance. The contents of each item are as shown in the figure, and therefore a detailed description thereof is omitted here.

Among the items shown in FIG. 13, the congestion degree,
The waiting time information, the reservation status, and the like are usually information for an event that is expected to occur at all times, and for example, the latest information can be transmitted at intervals of several minutes. In addition, equipment failure,
It is preferable that emergency information such as temporary closure of facilities in the venue due to bad weather can be promptly transmitted at any time.

Examples of the static information include permanent event information which is carried out in units of week, month, season, etc., specific information which is information of events held only at a certain time on a specific day, and the like. Also, although not currently implemented, in the future
Notice information, which is information on events scheduled to be held,
It is treated as static information. Since these static information is information related to what is scheduled, once input at the required time, there is no need to update until the end of the period, and it changes within one day, for example. Since it is not information that changes from moment to moment, it is treated as static information.

Items constituting such dynamic / static information are common to some extent in a specific area such as a theme park or a department store, so it is convenient for the system configuration to be fixed. However, when transmitting characteristic information in a certain area,
For example, as shown in FIG. 13, when notifying the number of visitors today or transmitting detailed information on the facility, commercials, etc., as other dynamic information, or other static information, Just send it.

FIG. 5 is an external view of the portable device 4. Although not shown, the size is so large that it fits in the hand and fits in a pocket of clothes.

As means for the mobile unit 4 shown in FIG. 5 to transmit information to the user, two means are shown: a means for displaying and outputting on the display section 50 and a means for outputting voice from the speaker 57. It is also preferable to appropriately employ a method of notifying the user that information has been received by vibration or heat.

Next, a method of using the portable device 4 will be briefly described.

First, the power is turned on by operating the power-on means (not shown). After power on, a1 to a8
A deformed map is displayed on the display unit 50 such that the rectangular shape with alphanumeric characters indicates “facility”, the circle indicates “rest”, and the other spaces indicate “passages”. From a1
Actually, a8 displays a facility name and a mark that represents the facility, but here, for ease of explanation,
Symbols are attached. The positions a1 to a8 may correspond to the installation location of the ground communication device, and further correspond to the ID number transmitted by the ground communication device.

When the facilities are close to each other and it is not necessary to install the ground communication device unique to the facilities, there is a case that the ground communication device corresponding to the facility is not provided. Do not necessarily have a one-to-one correspondence. In addition, when a ground communication device is needed even near the entrance of the facility, the ground communication device may be installed, but it is not necessary to display the position of such a ground communication device.

Here, the map data to be displayed is the portable device 4
The data may be stored in advance in the memory and the stored data may be displayed. Regarding the position of the user himself / herself, the current position mark 52 is not displayed until data is received in the communication area 7 of any of the wireless base communication devices 2 in order to specify the current position.

When the portable device 4 comes to exist in the communication area 7, the present position mark 52 is displayed as shown in FIG. Since the wireless base communication device 2 is installed near the entrance of the facility, when the ID number is received, there are many users near the entrance, so which facility is the user in front of? By checking the current position mark 52 and looking at the map information, it is possible to immediately grasp the positional relationship of other facilities.

On the pop-up screen 51, as shown in the figure, the information specified by the user is displayed. This display is
By default, information about a facility that is heavily congested may be preferentially output, or a location that the user often selects may be registered in the function key 53 and the desired function key may be selected. By pressing, the facility name and corresponding information are displayed, or by moving the cursor 58 to a desired position with the direction keys 55 and pressing the enter key 56, the facility name of the specific facility, It may be possible to display corresponding information.

Reference numeral 54 is a ten-key pad, which is used for inputting numbers. For example, if the input operation of the command for displaying and outputting the information of a specific facility is to press the enter key 56 after inputting a two-digit number, operate this numeric keypad to
You can display it. In such a case, it is preferable that the two-digit number and the facility are displayed in association with each other.

In the function key 53,
It may include a function for designating display of any information, for example, waiting time, congestion degree, and the like. In order to display the necessary information, various methods such as a method using a touch panel and a method using a pull-down menu bar for setting can be considered, and any method may be adopted.

Although FIGS. 1 to 5 have been described as a system for performing unidirectional communication from the terrestrial communication device 20 side to the portable device 4 side, it is also possible to adopt a system capable of bidirectional communication. is there.

In this case, as shown in FIG. 6, both the ground communication device 20 and the portable device 4 need to have a transmitting / receiving function. The two-way terrestrial communication device 60 changes the configuration of the wireless base communication device 2 included in the one-way communication terrestrial communication device 20.

The hardware configuration of the wireless base controller 1 does not need to be changed, and the CPU 28
It can be dealt with by improving the software for. However, in order to distinguish from the one-way communication, the wireless base controller 1 is
It is shown as a two-way wireless base controller 61.
A specific storage area in the memory 22 is used as an ID management memory described later.

First, the bidirectional wireless base communication device 64 will be described with reference to the drawings.

Basically, each component of the wireless base communication device 2 is changed to be bidirectional, and the modulator / demodulator 63 that modulates information to be transmitted and demodulates received information.
And a transmission / reception unit 65 that actually transmits / receives radio signals and a transmission / reception control unit 66 that controls transmission / reception.

The download data sent from the bidirectional wireless base controller 61 is modulated by the modulation / demodulation unit 63 and transmitted from the transmission / reception unit 65, and conversely, the bidirectional portable device 70.
The data (referred to as “upload data”) transmitted from the receiver / receiver 65 is received by the transmitter / receiver 65,
3 demodulates and outputs to the two-way wireless base controller 61.

By processing this upload data, as will be described below, a more convenient information providing service can be provided as compared with one-way communication. For example, the two-way portable device 70 is configured to be able to transmit the ID number of the portable device itself, and the ID number is stored in the ID management memory 62, which is specially set in the memory 22, together with the time information. Keep it. At this time, in order to grasp the time information, the ground communication device is configured to have a clock.

In FIG. 15, in the ID management memory 62,
Indicates the storage status of information. As can be seen with reference to FIG. 15, it comprises a group ID code, an individual ID code, a captured ground communication device, and time information. The captured ground communication device and time information are configured to be addable or updatable each time an ID is received from the portable device side.
The latest information is saved.

The personal code is the ID number of the portable device transmitted by the portable device, the captured ground communication device indicates the ground communication device that received the ID number, and the time indicates the time when the ID number was received. The group ID code is information indicating the grouping of portable devices, and a plurality of individual ID codes defined in advance so as to have the same group ID form the same group.

For example, if the "group ID code" is "A0
The members of the group of "1" are personal code "000",
They are "001". The information shown in FIG.
Information is periodically transmitted and received between the terrestrial communication devices, and information stored by other terrestrial communication devices can be acquired by the specific terrestrial communication device.

By referring to the information thus stored, the terrestrial communication device can return the information on the location and time of the portable device to which the bidirectional portable device 70 has made an inquiry. With this function, if the members of the group are in a state where they cannot understand each other's existing positions, if you make an inquiry to the terrestrial communication device, you can immediately check the existing positions of other members. It will be possible to provide a service that will let you know.

The bidirectional portable device 70 is substantially the same as the portable device 4 in its configuration, and includes a bidirectional antenna 68 capable of transmitting and receiving, a modulation / demodulation device 67 capable of modulating and demodulating, and the antenna 30 shown in FIG. , Is provided instead of the demodulator 31.

By operating the function keys 53 and the ten keys 54 shown in FIG. 5, it is possible to give a request to the two-way ground communication device 60. In the configuration provided with the touch panel, the required function may be added to the panel key.
In this way, the output processing of the request signal to the two-way ground communication device 60 may be handled by changing the processing program of the main control processor 33. The contents of the two-way communication service will be specifically described later.

First, the information communication system will be described with reference to FIG. That is, in FIG. 7A, the communication state of the downlink information 100 and the uplink information 101 that are communicated in the direction of the arrow between the two-way ground communication device 60 and the two-way portable device 70 is shown. It is shown schematically. Further, FIG. 7B shows a transmission format of downlink information 100 and uplink information 101.

The downlink information 100 is, as shown in the information content outline, the ID number 102 of the ground communication device, the dynamic / static information 103 of each point, and the uplink information 10.
Transmission information consisting of a response 104 to 1 is shown. Such transmission information is transmitted cyclically,
When the two-way portable device 70 exists in the communication area, the two-way portable device 70 is synchronized and can immediately receive various information.

The individual frame has a data structure as shown in an enlarged form below.

The format of the terrestrial communication device ID transmission 102 is a synchronization control signal 105 which is data for synchronization control.
(Usually special data called a flag sequence), a header 106 indicating that the ID number is transmitted,
It has an ID number 107 of the terrestrial communication device and an error check code 108 for confirming whether or not the data can be correctly received by the two-way portable device. The format configuration of the static / dynamic information 103 of each terrestrial communication device is also the same.
05, a header 109 indicating that static / dynamic information is transmitted at each point, an actual data section 110, and an error check code 111. The information is continuously transmitted if there is a plurality of information to be transmitted from the ground communication device 60 side. Then, the two-way communication portable device 7
From 0, the response signal 104 when there is a request is transmitted.

The format of the response signal 104 is also similar to the format of the above-mentioned two information, and is a format in which each response from each two-way portable device 70 is framed and transmitted.

Since the format of the response signal 104 indicates the signal 105 for synchronization control, the header 112 indicating the response signal 104, and which bidirectional portable device 70 the response is to, the portable device inquired. A target portable device ID number 113, response data 114, and an error check code 111. To indicate which interactive mobile device 70 the response is, the ID number of the portable device 70 is added to the response 104. Therefore, the interactive mobile device 70 detects this ID number and sends it from its own portable device. Only the data recognized as the response to the issued request may be fetched and notified to the user, a portable device with a small memory capacity and the like can be realized, and the user is not bothered by irrelevant information.

Next, the format of the uplink information 101 will be described. The format of the uplink information 101 is the synchronization control 105, the header 116 indicating that there is an inquiry, the own machine ID number 117, the inquiry content 118, and the terrestrial communication device 60 includes an error check code 119 for correctly receiving the data. Configured to have. If there is no inquiry (request), the header 116 indicates that there is no request, and the ID number 11
Information is intermittently transmitted according to the format in which only 7 is added. Intermittent information transmission means that even if information is transmitted when communication with the terrestrial communication device cannot be performed, electric power is only wasted, and in order to prevent battery drain, intermittent information transmission is performed. Information is transmitted. Since it is not necessary to continuously send information even within the communication area, there is no practical problem even if the transmission is repeated in the unit of seconds, and it is preferable to suppress the consumption of the battery.

FIG. 14 shows the information content when the uplink operation is performed.

Although the group position confirmation information, the detailed inquiry information and the like are illustrated, it goes without saying that the information is not limited to these. Since the detailed contents of each item are as shown in the figure, detailed description will not be given.

When the uplink operation is performed,
Since it is possible to know the location of the two-way portable device 70,
In the uplink operation, if you issue a group position confirmation request,
Group location information is returned as a downlink response.

Here, the group position information is information indicating where each member forming a certain group is located. Note that how to respond to the group position confirmation request will be described later.

In order to respond to the group position confirmation request, it is necessary to define information on how the ID numbers of the portable units are grouped before the system is activated.

Further, in consideration of the maximum value of the transmission rate, if it is desired to know the detailed information about the specific facility only in a specific facility, a request command for inquiring the detailed information is transmitted by the uplink operation. Then, if the inquired user receives the response, it becomes possible to provide a detailed information providing service while suppressing an increase in traffic.

Here, the data format used when the downlink operation is performed in the one-way communication will be described.

The data format in this case is very simple, and it may be assumed that there is no response 104 to the uplink information in the downlink information (100) transmission format shown in FIG. Since there is no uplink operation itself, the uplink information (101) transmission format is not necessary. That is, the ground communication device 20 only repeatedly transmits the ground communication device ID number 102 and the static / dynamic information 103 of each point.

The downlink information is received by the portable device 4, stored in the memory 34, and in accordance with the command set by the operation of the operating device 38, the main control processor 33.
Performs predetermined display processing and audio output processing. Further, the user is informed of all the received information stored in the memory 34, and the specified information is provided from the accumulated information in accordance with the instruction given by the user.
It is also preferable to be configured to answer.

Since the portable device 4 can receive a large amount of information only with the downlink information, it is considered difficult to notify the user of all the information at one time. It is also preferable that the information is stored and appropriate information is output by a user's inquiry operation to the portable device 4, that is, a pressing operation of the function key 53 shown in FIG. The function key 53 may be function-set so that necessary information can be retrieved. For example, the function setting of the function key 53 may be set so that the information corresponding to each item shown in FIGS.

In any one of the unidirectional and bidirectional communication systems, the ground communication device transmits its own ID number, the portable device receives the ID number, and the portable device receives a map within a specific area. It is necessary to retain information. Then, as described above, the portable device can detect its own position by referring to the ID number of the ground communication device and the map information held by the portable device. If the position information of is held, the action record can be kept.

By referring to this action record and the destination designated by the cursor 58 or the like in advance, the route information for reaching the destination is programmed so as to be output, and the main control processor 33 outputs this route information. Be sure to perform the processing according to the program.

Further, if it is configured such that data of a file structure having a function of adding some information, for example, an editing function capable of writing information in a hierarchical manner can be stored, a unique message or the like can be treated as output information. Since it can be recorded and left together, a portable device with excellent convenience can be provided.

Further, in the system having the bidirectional communication function, the position of the user can be grasped by tracing the ID number output from the portable device on the side of the ground communication device, as described above. By monitoring the same ID number in time series, the terrestrial communication device can recognize from which direction the user has progressed before reaching the current location.

The information shown in FIG. 16A may be stored in the ID management memory 62. As can be seen by comparing with FIG. 15, the information of “destination” is newly added. This information is input by the user when he / she enters the specific area or finishes the use of each facility and then heads to the next target facility. For example, a coded facility number or the like may be input.

Further, time information is sequentially stored for one user, and although only three types of time information are stored in the figure, the captured ground communication device and time information are stored. Are configured so that they can be newly stored in sequence. That is, the communication history of a certain portable device with the ground communication device can be accumulated in time series. A storage device for storing such information may be provided in each ground communication device.

[0120] Such information is configured to be periodically exchanged between the ground communication devices.

In addition, all the terrestrial communication devices shown in FIG. 16 are stored in the storage device provided in the management center or the specific terrestrial communication device.
The information shown in (a) may be stored so that all the ground communication devices can access it regularly.

As shown in FIG. 16A, the group ID
The captured ground communication device IDs of the portable device corresponding to the code “A01” and the personal ID code “000” are “01
3-0818 "," 013-0819 "," 013-0 "
It is 820 ".

The terrestrial communication device incorporates a processing program so as to have a processing function of making the following determination with reference to time-series information and map information. This state is shown in FIG.
This will be described with reference to the display output screen of the portable device shown in FIG. The map information in the specific area provided in the portable device is also stored in the memory on the side of the ground communication device.

As can be seen by referring to the map information of FIG. 16 (b), the captured ground communication device IDs are "013
-0881 "," 013-0819 "," 013-08 "
20 ”, the user of this portable device is
It can be seen that the ground communication device C is reached from the direction of the arrow A, not from the direction of the arrow B of 6 (b). Here, as the route guidance information for reaching the destination (code “013-0821”), an instruction to turn left is output. Such an instruction may be given by voice, for example. As an example of the simplest algorithm,
The processing program may be configured such that the route guidance information is output corresponding to a predetermined number of sets of time-series data and destination data of each captured ground communication device ID.
However, it may be possible to deal with the problem by applying a route guidance technique that is put into practical use by a vehicle navigation device or the like.

In this way, it is possible to properly guide the route to the user and measure the action pattern of the user. It is possible to obtain valuable information for the operator, such as better facility layout, by analyzing the behavior patterns of users in a specific area.Note that such route guidance has only one-way communication function. It is feasible even in a system that does not. That is, in this case, the information (particularly, the captured ground communication device ID, the time, the destination) and the processing program as shown in FIG. 16A may be stored in the memory provided in the portable device. Good.

As shown in FIG. 17, the acquisition ground communication device I
A predetermined number of D, time, and destination information are stored from the latest one, and when the ground communication device ID “013-0820” is detected as described with reference to FIG. 17, it is determined that the portable device itself has reached the local point in the direction indicated by the arrow A with reference to the information and the map information, and the route guidance information for turning left is output. It should be noted that such a route guidance information providing technique may be dealt with by applying a route guidance technique that has been put to practical use by a vehicle navigation device or the like.

In this case, in the ground communication device,
Since information on the user's behavior pattern is not recorded, it is recommended that the facility operator analyze the user's behavior pattern by obtaining the information stored by the mobile device when the mobile device is collected. Good.

Next, the operating mode of the system for bidirectional communication will be described. Although the operation mode of the system in the case of performing unidirectional communication has been described with reference to FIGS. 1 and 2, the case of performing bidirectional communication is not so different from this case.

That is, the wireless base controller 1 and the wireless base communication device 2 shown in FIG.
1. It is only necessary to replace the mobile device 4 with the bidirectional wireless base communication device 64 and replace the mobile device 4 with the bidirectional mobile device 70 capable of bidirectional communication. Then, the information to be communicated is changed from that shown in FIG. 13 to that shown in FIG. 14, and the information providing service is performed. If the same replacement is performed, the ones shown in FIGS. 2 and 3 will also adopt the two-way communication system as they are.

In the form described so far, unidirectional,
Regardless of the bidirectional system, all ground communication devices installed independently for each facility within a specific area have the same hardware configuration and are static / dynamic with each other. We were thinking about building a system that exchanges information with each other and provides useful information to users, but for facility managers, a host control that can manage each terrestrial communication device at one place. It is often convenient to install the device.

FIG. 8 shows a mode in which the host control device 131 is installed in the management center 130 to construct a unidirectional communication system.

The host control device 131 manages the state of each ground communication device, processes the information sent from each ground communication device 20, and sends it as data to be sent to another ground communication device 20. And various other processes are executed.

As for the state management of each ground communication device performed by the host control device 131, a device which does not regularly exchange information with another device is judged to be in failure, and a message to that effect is displayed. It is conceivable to inform the operator by output or the like.

The load distribution between the host controller 131 and each terrestrial communication device differs depending on the scale of the system and the amount of data to be processed, and the system is constructed by distributing so that appropriate processing can be performed as a whole system. . Further, here, the case of the one-way communication system has been described as an example, but also in the two-way communication system, the management center 130 may be provided and the system design may be performed in consideration of optimization of load distribution. .

FIG. 9 schematically shows a form of network connection of the terrestrial communication device. The terrestrial communication device (20 or 60) is shown as connected in a ring shape. Further, although the host control device 131 is connected to the wired network, it does not necessarily have to be connected.

As shown in FIG. 10, it is conceivable to configure a star network centering on the host controller 131. In this case, the host controller 13
A ground communication device (20 or 60) is arranged around the area 1.

Further, it is conceivable that the networks are connected in a hierarchical manner, and various types of network connection modes are possible. Therefore, an appropriate connection form may be adopted when constructing the system. It is also possible to mix two-way communication and one-way communication terrestrial communication devices in one specific area. Considering the number of facilities provided and the shape of the specific area, etc. You should build the system in the form you think.

According to the embodiments described thus far,
The explanation has been given by taking a theme park, etc., which can be grasped relatively clearly by the visitors of a specific area, as an example, but change the processing content of the part that interprets and processes the information related to the position sent from the ground communication device. As a result, it is possible to realize a portable device used in another specific area. For example, when a place where GPS radio waves, which are widely used for car navigation, are hard to reach as the specific area, it is very effective to apply the system described so far.

[0139] As an example, in a subway yard, etc., the feeling of being on the ground is significantly different. Therefore, the user looks over the entire subway yard, confirms his / her position, and immediately grasps the direction of the destination. It is relatively difficult to do so, and application as a guidance system to such areas can be considered. In addition, it can be applied to a guidance system in various facilities such as airports, train stations, bus terminals, spacious museums, museums, libraries and schools. The information provided by the guidance system applied to such a facility may be set in various ways according to the characteristics of the facility.

FIG. 11 shows the external structure of the portable device to support various systems. As a basic process performed by the portable device, if the system only receives downlink information, not only the information that the wireless base communication device 2 that is actually communicating has but also the specific area There is a process of receiving information transmitted including information provided in another ground communication device and processing based on the received information, for example, a process of outputting information of the current position.

In addition, in the case of a system that handles uplink information, in addition to the above processing functions, the portable device has a transmission processing function for making an inquiry to the terrestrial communication device, and the terrestrial communication device has such a function. A response process is required to respond to the inquiry.

Therefore, if the basic processing functions are made common and the map information in each information providing service area can be easily exchanged, the system can be used in common with the system in other areas, which is simple and low-cost. It is possible to realize a portable device that can be used in other systems at low cost. Figure 1
1 describes a state in which map information corresponding to a specific area is recorded in a storage medium such as an IC card 150 and can be attached to and detached from the portable device 4. A PCMCIA type card, which has already been standardized, may be used, or a storage medium based on an original method may be used, but if it conforms to the standard, it is highly versatile.

It is needless to say that a floppy disk, a semiconductor ROM, a CD-ROM, a magnetic tape, or any other storage medium may be used instead of the IC card 150, and a rewritable memory device is built-in and stored from the outside. The contents may be rewritten. On the other hand, regarding the terrestrial communication device, it is only necessary to change the information provided at the time of system construction for each applicable facility such as subway, airport, etc., software change is necessary, but hardware change is not , Not accompanied.

Now, FIG. 12 shows a system for providing information providing service in the subway yard 160 as one mode applied to various systems. Subway premises 1
At 60, if the user is accustomed to the subway premises 160, he / she knows from an empirical rule what is in which direction, and does not hesitate about the direction of travel. Since it is not known in what direction what is present, that is, because there is no sense of direction, the information guide plate 164 is installed in most subway stations and is the only information source. However, since it is a guide for general users, optimum information is not necessarily presented personally.
However, it is an empirical fact that it may be difficult to grasp the direction in which one should proceed or the position of the transfer platform even if the guide plate is installed.

Therefore, as shown in FIG. 12, the terrestrial communication device of the information guidance system according to the present embodiment has a place where users gather, that is, near the ticket gate 161 and the entrance 162.
163 and so on (20-1, 20-2, 20
-3). If installed near the entrances 162 and 163, users can pass the information without fail so that they can effectively provide information. 165-1, 165-2, 166-1, 16
6-2 has shown the radio information transmitted from each ground communication apparatus.

Further, if the content of information is changed according to the transmission position of information, a more effective system can be constructed.
That is, from the ground-side device 20-1 installed near the entrances 162 and 163, information for users who mainly go out from the subway station to the ground and go to the town, that is,
Information such as the main land name of the city and tourist information on the main buildings is sent.

For the terrestrial communication device 20-2 installed in the middle of the passage on the subway premises, the transmission areas 165-1, 165-2, 16 as shown in the figure are shown.
6-1 and 166-2 are formed so that the antenna directivity is adjusted to the users moving from left and right,
Information suitable for the direction of movement is provided.

For example, the information received in 165-1 is set as the information indicating that the doorway 162 exists when moving leftward in the figure, and the information received in 165-2 is right in the figure. It may be set as information indicating that the ticket gate 161 and the entrance 163 exist in the direction. Ground communication device 2
The information transmitted from 0-3 is general wide area information about the subway premises. Such wide area information includes, for example, weather information near the exit, departure / arrival status of buses, distance to the exit, departure / arrival time of the transportation means when changing to another transportation means, and congestion status of the transportation means. And the like.

The portable device 4 acquires the map information on the subway premises from the IC card 150 and outputs it to the display unit, and based on the map information and the ID number of the ground communication device,
The current position of the user is detected, the current position is displayed on the map, and the information sent from the ground communication device is notified to the user by display or voice.

Of course, since it is possible to view the information together with the existing guide plates, it is possible to more accurately grasp the information about the subway premises and the ground. Further, it is natural that both the ground communication device and the mobile device may be devices capable of bidirectional communication, but if the device is a bidirectional type, it may be difficult to understand the information to be communicated beforehand. It is also possible to build a system that makes inquiries of a specified type and responds to them.

Here, the subway yard guidance system has been described with reference to FIG. 12 as an application form of this system. Map information to be recorded in the IC card 150 is
If changed according to the facility to be used, it is possible to construct a system capable of providing useful information to the user of the facility. For example, it can be applied to various kinds of facilities such as department stores, museums, airports, etc. as described above.

Finally, another embodiment in which the present system is applied to a subway premises will be described.

FIG. 18 shows the subway premises shown in FIG.
It is a display form for displaying transmitted information when moving in an underground mall. This display form is different from the display form described in FIG. Underground (for example, on a subway premises,
When moving in an underground shopping area, an underpass, etc., it is often the case that it is possible to improve the convenience of the user if the geographical information on the ground corresponding to the underground can be grasped. In the display form shown in FIG. 18, the underground map information and the corresponding ground map information are recorded in the portable device in association with each other, and when the underground map information is displayed, this is recorded. The present embodiment is characterized in that the corresponding ground map information is also displayed.

The present location mark 17 is displayed on the display unit of the portable unit 4.
2 (ground side) and 173 (underground side) as well as underground and ground map information are displayed. The actual current position of the user is the position indicated by 173 in the underground. Therefore, 172 is a point existing vertically above 173. The map information is recorded in a storage medium such as the IC card 150 in which the underground information and the ground information are associated with each other, and the display based on the recorded information is performed. Alternatively, two types of map databases may be prepared, and two map information may be displayed in association with each other by referring to each map database by the process in the portable device.

As a display method, as shown in the figure, the ground map 170, which is a plan view, and the underground map 171, which is a plan view, may be displayed by dividing one display unit, or may be displayed on the ground. The underground situation may be displayed three-dimensionally.

Incidentally, in addition to the relationship between the ground and the underground, it is effective to display the upper and lower floors in association with each other.
There are airports, department stores, and the like, which can also be dealt with by appropriate placement of the ground communication device and change of map information stored in the IC card 150.

For buildings having three or more floors, the display screen is divided into a number of floors,
By displaying it, the convenience of the user can be improved.

The display processing described with reference to FIG. 18 may be activated, for example, when the portable device receives specific transmission information. Examples of the specific transmission information include information indicating that the ground communication device is installed in a specific place, for example, information indicating that the ground communication device is installed underground.

As described above, according to the present invention, a system for providing useful information to a user who owns a portable device can be realized by a plurality of communication devices installed in a specific area.

[0160]

As described above, according to the present invention, the user can grasp not only static information but also dynamic information corresponding to each facility. , You can immediately make an efficient action plan that suits you. Also, based on the ID number transmitted by the ground communication device,
Since the user's presence position can be detected, special ground equipment for position detection is not required, and the mobile device that is generally used can be changed only slightly and has a simple system configuration. It is possible to build a system while preventing cost increase.

Further, since it is possible to appropriately provide detailed information useful for the user to the facility manager who provides the information, it is possible to provide the information service which is highly satisfied by the user. In that case, since information such as a notice can be provided, it is possible to realize a system that is highly convenient for the user.

Also, the operation of the portable device is simple, and useful information can be obtained immediately. The route guidance to the user can be appropriately performed, and from this point as well, a system that is highly convenient for the user can be realized.
