A portable information terminal such as 8 is shown. These devices 5 to 8 are connected to a public network 9 such as a mobile phone communication network or the Internet.

  2 and 3 are conceptual diagrams showing an example of the installation position of the card reader in the present embodiment. Employees who are allowed to enter the factory are given an identification card such as an employee ID card, and the employee always carries the identification card when entering or leaving the factory or when moving around the factory. A security gate 2 is installed at each entrance / exit of the factory. An entrance card reader 4a is installed outside the security gate 2, and an exit card reader 4b is installed inside the security gate 2. ing. The ID controller 20a is provided for each entrance and exit, and connects the corresponding security gate 2 and card readers 4a and 4b. In FIG. 1, only one ID controller 20a is shown. In addition, a door with an electric lock 3 is installed at each entrance and exit of each building in the factory and each room in the building, and an entrance card reader 4c is provided on the outside of the door. Inside, the outgoing card reader 4d is installed. The ID controller 20b is provided for each door provided with the electric lock 3, and connects the corresponding door and the card readers 4c and 4d. In FIG. 1, only one ID controller 20b is shown.

  As illustrated in FIGS. 2 and 3, the entrance card reader 4c and the exit card reader 4d are also installed at the entrances and exits of rooms such as rooms without doors, stairs, and elevator halls in the building. It may be possible to grasp and manage user traffic.

  In the following description, the card readers 4a, 4b, 4c, and 4d provided on the outer side and the inner side have the same function of reading the data recorded on the identification card except for the different installation positions. For convenience, when there is no need to distinguish between them, they are collectively referred to as “card reader 4”. Further, the ID controllers 20a and 20b have the same function except that they are connected to the security gate 2 or the electric lock 3 provided on the door. It will be collectively referred to as “ID controller 20”. Similarly, the personal information storage units 21a and 21b are generically named. Furthermore, in the present embodiment, points where card readers such as entrances and exits and entrances and exits are installed and where people enter and exit are managed by the entrance / exit management server 10 are collectively referred to as “entrance / exit”.

  When the employee or the like passes through the doorway, the employee or the like holds an employee card or the like over the card reader 4 installed at the doorway. When the card reader 4 reads the identification information recorded on the employee ID card, the card reader 4 transmits the read identification information to the ID controller 20. When the identification information is transmitted, the ID controller 20 compares the identification information with the personal information stored in the personal information storage unit 21 and performs user authentication. If the authentication is successful as a result of the authentication, the security gate 2 and the like are unlocked and the passage through the entrance is permitted. The ID controller 20 transmits to the entrance / exit management server 10 traffic information including the date and time of traffic, the traffic type (entry or exit), identification information of the user who passed, name, affiliation, and the like. The traffic type is set to “entry” when the employee card is read by the entry card readers 4a and 4c, and “exit” when the employee card is read by the exit card readers 4b and 4d. The As described above, the traffic information is generated every time the user passes through the entrance and is transmitted to the entrance / exit management server 10.

  The entrance / exit management server 10, when sent from the ID controller 20, includes, in its passing information, a section name (for example, entrance / exit # 1, entry / exit) that specifies the place where the ID controller 20 has been identified. The exit history information is added to the exit history # 2 and the like, and the travel history information is generated and stored in the travel history information storage unit 12. In the above processing, the traffic history information accumulated in the traffic history information storage unit 12 is generated with the above-described data configuration. For example, personal information such as time, name, and affiliation is stored in the entrance / exit management server 10. It may be added on the side.

  The function for managing the entry / exit of the person described above is realized by the ID controller 20, its connected device, and the entrance / exit management server 10. This function is realized by using the existing entrance / exit management system as it is. May be.

  Although there may be a difference in performance, since the entrance / exit management server 10 and the ID controller 20 are also realized by a computer, the hardware configuration may be illustrated in the same manner as in FIG.

  FIG. 5 is a block configuration diagram of the congestion information management server 50 in the present embodiment. The congestion information management server 50 in this embodiment includes an information acquisition unit 51, a congestion information generation unit 52, a request reception unit 53, a congestion information provision unit 54, a congestion history information generation unit 55, a congestion avoidance route provision unit 56, and a predicted congestion. An avoidance route providing unit 57, an information distribution unit 58, and an information management unit 59 are provided. Further, as various information storage means, a traffic history information storage unit 61, a congestion determination information storage unit 62, a congestion information storage unit 63, a congestion history information storage unit 64, a search history information storage unit 65, a system setting information storage unit 66, A notification destination information storage unit 67 and an automatic distribution information storage unit 68 are provided. The information acquisition unit 51 acquires the travel history information stored in the entrance / exit management server 10 and stores it in the travel history information storage unit 61. Since the registration contents of the traffic history information storage unit 61 are desirably the same as the traffic history information storage unit 12 from the viewpoint of reliability of congestion information and the like described below, the information acquisition unit 51 includes a traffic history information storage unit. The traffic history information that is not registered in the traffic history information storage unit 61 is acquired from the entrance / exit management server 10 every time the traffic history information is written in the memory 12 or at a short predetermined time interval. The congestion information generation unit 52 refers to the traffic history information storage unit 61 and the congestion determination information storage unit 62, analyzes traffic history information, generates congestion information indicating the degree of congestion at each doorway, and stores the congestion information storage. Register in the unit 63. The request reception unit 53 receives various information provision requests sent from the PCs 5 and 7 or the mobile phones 6 and 8. The congestion information providing unit 54 provides the generated congestion information to an information providing request source or the like. The congestion history information generation unit 55 generates congestion history information by adding date and time information specifying the date and time when the congestion information is generated to the congestion information registered in the congestion information storage unit 63, thereby generating congestion history information. Register in the storage unit 64. The congestion avoiding route providing unit 56 refers to the congestion information storage unit 63 and the congestion history information storage unit 64 in response to a route search request from the user, and considers the degree of congestion obtained by analyzing the congestion history information. A congestion avoidance route (congestion avoidance route) that the user moves from the current location to the destination is specified and provided. The predicted congestion avoiding route providing unit 57 refers to the congestion history information storage unit 64 and the search history information storage unit 65 in response to a predicted route search request from the user, and obtains it by analyzing the congestion history information and the search history information. The predicted congestion avoidance route (the predicted congestion avoidance route that the user moves from the departure place to the destination is identified and provided to the user in consideration of the predicted congestion level. The information distribution unit 58 is congested with the applicant. The information management unit 59 distributes the information, etc. The congestion management information storage unit 62, the system setting information storage unit 66, the notification destination information storage unit 67, the automatic distribution information storage unit 68, etc. Maintenance management such as registration, update, and deletion of information that the system should prepare in advance.

  FIG. 6 is a diagram showing an example of the data configuration of the congestion determination information preset in the congestion determination information storage unit 62 in the present embodiment. In the present embodiment, the degree of congestion is obtained for each doorway as an index indicating whether each doorway is congested. In the congestion determination information storage unit 62, a threshold for obtaining the degree of congestion at each doorway is set in advance for each doorway. Specifically, the congestion determination information associates the card reader verification duration set for each level (three levels in the present embodiment) and the card reader verification interval with the section name which is the identification information of each doorway. Configured. FIG. 6 shows an example of setting only one doorway (door # 1). The card reader verification interval refers to the time interval at which this user authentication is performed. The card reader verification duration is the length of time that the card reader verification interval lasts. For example, when the user authentication is executed continuously for 1 minute at 1 second intervals and when the user authentication is executed continuously for 1 minute at 5 second intervals, the former passes 5 times more people per minute. I can say that. That is, it can be determined that the former is congested. Although the traffic volume within a predetermined time can be calculated from the card reader verification interval and the card reader verification duration time, the congestion information generation unit 52 has a traffic volume that is greater than or equal to the level 3 setting based on the setting of the congestion determination information. If the traffic volume is level 3, the level 2 setting is less than the level 3 setting, the level 2 is set, and if the traffic volume is the level 1 setting or more and less than the level 2 setting, the level 1 is set to the level 1 If it is less than level 0, the degree of congestion can be obtained. In this setting example, the larger the level value, the more crowded.

  Here, the congestion level is determined based on collation based on information read from the card reader 4, that is, execution of user authentication. However, the present invention is not limited to this. For example, the congestion level is determined by executing the reading of the identification card by the card reader 4. May be obtained. In the present embodiment, the degree of congestion is shown in four stages of levels 0 to 3, but the number of levels is not limited to this example. Further, the degree of congestion may be obtained using an index different from the card reader verification duration time and the card reader verification interval.

  A time interval for generating congestion history information is set in advance in the system setting information storage unit 66, and the congestion history information generation unit 55 stores the congestion history information at the time interval set in the system setting information storage unit 66. Generate.

  FIG. 7 is a diagram showing an example of the data configuration of the notification destination information registered in the notification destination information storage unit 67 in the present embodiment. The notification destination information is configured by associating a user ID for identifying a user with personal information such as the name, password, and affiliation of the user and a destination for identifying the destination of the information. In the example shown in FIG. 7, since a mail address is set as a destination, the congestion information providing unit 54 that provides information distributes the information to be sent as an attached file of the electronic mail. In addition, a URL and an e-mail address that specify a storage location of information may be set as a destination so that the information can be browsed by a browser.

  FIG. 8 is a diagram showing an example of the data configuration of the automatic distribution information registered in the automatic distribution information storage unit 68 in the present embodiment. The automatic distribution information includes a user ID for identifying a user who desires automatic distribution, a distribution date and time for which distribution is desired, distribution target information in which a type of information desired to be distributed at each distribution date and time, and a distribution destination of the information. Configured in association. In addition, as illustrated in FIG. 8, a plurality of dates may be set as the delivery date. In addition, a plurality of types may be designated as information desired to be transmitted at each delivery date and time, and a plurality of delivery destinations may be designated.

  The components 51 to 59 in the congestion information management server 50 are realized by a cooperative operation of a computer that forms the congestion information management server 50 and a program that operates on the CPU 41 mounted on the computer. The storage units 61 to 67 are realized by the HDD 34 mounted on the congestion information management server 50. Or you may implement | achieve with the memory | storage means on the other computer accessible via a network.

  Further, the program used in this embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or DVD-ROM. The program provided from the communication means or the recording medium is installed in the computer, and various processes are realized by the CPU of the computer sequentially executing the installation program.

  Next, the operation of the congestion information management server 50 in this embodiment will be described.

  As described above, the information acquisition unit 51 in the present embodiment acquires the traffic history information from the entrance / exit management server 10 to keep the traffic history information storage unit 61 in the latest state. And in this Embodiment, congestion log | history information is produced | generated regularly. The congestion information may be generated each time in response to an information transmission request from the user. However, when a plurality of requests are received at the same time, the same processing is repeatedly executed. Let's generate it regularly.

  First, the congestion information generation unit 52 generates congestion information by analyzing the traffic history information accumulated in the traffic history information storage unit 61 and registers it in the congestion information storage unit 63. Specifically, the congestion information generation unit 52 calculates the amount of traffic for each doorway by counting the number of passers-by who have passed through the doorway within a predetermined period in a predetermined cycle. Furthermore, the congestion information generation unit 52 refers to the congestion determination information storage unit 62, and determines the congestion level from the traffic situation of the entrance and exit as an index indicating the degree of congestion for each entrance and exit. The congestion information generation unit 52 analyzes the traffic history information, thereby performing a time interval for performing user authentication within a predetermined period, a card reader verification interval, in other words, when user authentication is continuously performed. The time length is obtained, and each obtained value is compared with the congestion determination information preset in the congestion determination information storage unit 62 to determine the current congestion level. In this way, the congestion information generating unit 52 generates the congestion information by associating the number of passers-by who have passed through the doorway and the congestion level for each doorway specified by the section name.

  When the congestion information generation unit 52 generates the congestion information, the congestion history information generation unit 55 adds the date and time when the congestion information was generated to the congestion information to generate the congestion history information, and stores the congestion history information. It accumulates in the part 64. As described above, the congestion history information is generated as information indicating the congestion status of each doorway when the congestion information is generated.

  The above congestion information and congestion history information are generated by periodic processing. Next, FIG. 9 shows processing for providing a user with information useful for route selection that avoids congestion in response to a request from the user. This will be described with reference to the flowchart shown.

  When the request reception unit 53 receives an information transmission request from a user (step 101), the request transmission source user is authenticated (step 102). This is performed by collating the user ID and password included in the information transmission request with the user ID and password set in the notification destination information. When the user authentication is successful, if the received information transmission request is a congestion information transmission request (Y in step 103), the congestion information providing unit 54 reads the congestion information from the congestion information storage unit 63 (step 104). The congestion information corresponding to all the entrances / exits may be read out or a part thereof may be read out. As some examples, for example, when the device that transmits the information transmission request is a mobile phone 6 or 8 equipped with a GPS (Global Positioning System) function as a positioning function, the current location of the user is specified in the information transmission request. The location information may be included, and the congestion information providing unit 54 may read the congestion information related to the entrance / exit near the location that can be identified from the location information. Alternatively, if it is a work time zone, an entrance that passes from the current location to the location of the department to which the user belongs as the destination may be read. When the user is outside the site, the entrance / exit that passes from each entrance / exit to the location of the department to which the user belongs may be read. Alternatively, at the time of lunch, the entrance / exit that passes from the location of the user's department to the cafeteria may be read out. In this way, congestion information to be read may be narrowed down according to the user's current location and time zone.

  When the congestion information is acquired as described above, the congestion information providing unit 54 provides the congestion information to the requesting user (step 105). An example of providing the congestion information in a graphical display is shown in FIG.

  FIG. 10 shows an example in which a floor plan of the whole factory, entrance / exit and a building entrance / exit are displayed, and ellipses are superimposed on the crowded entrance / exit. The congestion level is represented by the size of the ellipse and the display color. By referring to the congestion information illustrated in FIG. 10 on the screens of the PCs 5 and 7 and the mobile phones 6 and 8 from which the congestion information transmission request is issued, for example, a user outside the site can enter from the crowded north gate. This makes it possible to select a route that uses the East Gate.

  In addition, as a method of providing congestion information, text information and image information as illustrated in FIG. 10 are converted into an electronic file to be attached to an e-mail, or image information storage location information (URL) is e-mailed. You may be notified. The providing method may be determined in advance, or may be set in the notification destination information and may be provided in a format desired by the user.

  When the received information transmission request is a route search request (Y in Step 106), the congestion avoiding route providing unit 56 reads the congestion information from the congestion information storage unit 63 (Step 107). Since the route search request includes information specifying the current location of the user and the destination, the congestion information to be read is limited to the congestion information of the entrance / exit that may pass while moving from the current location to the destination. May be. For example, information on building B when moving from outside the factory to building A is unnecessary. Information for specifying the current location of the user is positioning information in the case of the mobile phones 6 and 8 equipped with the GPS function. Further, when the route search request from the PC 5 installed in the factory does not include information for specifying the current location, the congestion avoiding route providing unit 56 searches for personal information and the like managed by another system and installs the PC 5. You may get the location.

  When the corresponding congestion information is acquired, the congestion avoiding route providing unit 56 analyzes the acquired congestion information and performs processing such as aggregation to calculate the degree of congestion of each route from the current location as the departure point to the destination. . Then, a route that minimizes the degree of congestion is obtained (step 108). In this route, the congestion level at each doorway existing between the starting point and the destination in each route is totaled, and the route having the minimum value is obtained as the route having the minimum degree of congestion. In the present embodiment, the route with the smallest degree of congestion is referred to as a “congestion avoidance route”. Note that the route for obtaining the total value between the current location and the destination may be obtained by obtaining map information of the entire factory and selecting a route to be processed from among the map information. Moreover, when calculating | requiring a congestion avoidance route, you may consider the difference of the labor required for movement, such as a staircase and an elevator.

  For example, a load level corresponding to the labor is set in advance at a place of a passage that requires labor. Specifically, a higher load level is given to the staircase walking with his / her feet than the escalator. Or you may make it set a negative load level to the place where the effort of movement is reduced. Then, when obtaining the degree of congestion of each route, the load level given to the place where the movement is required on the route is added as the congestion level to the congestion level included in the congestion information. Thus, in order to take into account the load level according to the effort required for movement when calculating the degree of congestion of the route, the degree of congestion of each route is not limited to the congestion level included in the congestion information, Alternatively, it may be obtained in consideration of the load required for movement.

  When the congestion avoidance route is obtained as described above, the congestion avoidance route providing unit 56 provides the congestion avoidance route to the user who transmitted the request (step 109). As a providing method, it may be provided by character information or image information as in the case of congestion information.

  In step 108, not only the route with the smallest congestion degree is determined, but each route is ranked according to the obtained congestion degree of each route, and only the route with the smallest congestion degree is presented to the user. Alternatively, a plurality of routes other than the route that is the smallest in order of the degree of congestion, such as the route with the second smallest congestion degree and the third smallest route, may be provided. The number of routes to be provided may be determined in advance, or a threshold value of the degree of congestion to be provided to the user may be set in advance, and routes that are less than the threshold value may be provided. If all routes are equal to or greater than the threshold value, a notification to that effect may be made so as not to provide the congestion avoiding route, or only the minimum route may be provided. The congestion avoiding route providing unit 56 may always provide the plurality of routes, or may provide them according to an instruction from the user. This applies not only to the congestion avoidance route but also to the predicted congestion avoidance route described later.

  When the received information transmission request is a predicted route search request (Y in step 110), the predicted congestion avoiding route providing unit 57 stores the congestion history information from the congestion history information storage unit 64, and stores the search history information as the search history information. Each is read from the unit 65 (step 111). Since the predicted route search request includes the departure point and the destination, the congestion history information to be read out may be limited to the congestion information of the entrance / exit that may pass while moving from the departure point to the destination. Good. For example, information on building B when moving from outside the factory to building A is unnecessary. In the case where the current location of the user can be specified, such as a predicted route search request issued from the mobile phone 6 or 8 equipped with the GPS function, if the departure location is not specified, the current location may be set as the departure location. The predicted route search request further includes a departure date and time or an arrival date and time at the destination, and the predicted congestion avoiding route providing unit 57 sets a time close to the departure date and time or arrival date as the departure date and time. The set search history information may be selected.

  Here, the data structure of the search history information stored in the search history information storage unit 65 will be described by first describing step 114 executed in the subsequent processing. As described above, when a predicted route search request is received from the user, the predicted congestion avoiding route providing unit 57 specifies the identification information (user ID) and name of the user who has issued the predicted route search request, and the predicted route search request. The search history information is generated and searched by adding date and time information for specifying the date and time according to the predicted route search request to the specified search condition, specifically, the departure place (current location), the destination and the departure date and time or arrival date and time. The information is accumulated in the history information storage unit 65. Note that the date and time according to the predicted route search request is the received predicted route such as the date and time when the predicted route search request was received or the date and time when the search result (predicted congestion avoidance route) was obtained according to the predicted route search request. Any date and time may be specified based on the search request.

  Therefore, the search history information acquired by the predicted congestion avoiding route providing unit 57 to obtain the predicted congestion avoiding route in step 111 described above is the departure date / time or the time close to the arrival date / time specified in the predicted route search request. The search history information set in the arrival date / time may be read.

  When the congestion history information and the search history information are read as described above, the predicted congestion avoiding route providing unit 57 first designates the predicted route search request by analyzing the congestion history information based on the past congestion results. The degree of congestion of each route that can be selected as a difference moving from the departure place to the destination at the departure date and time determined is obtained. If the arrival date / time is specified in the predicted route search request, the departure date / time is estimated from the specified arrival date / time and the location / rejection relationship of the departure location and destination, and the departure location is determined based on the estimated departure date / time. The degree of congestion of each route when moving from to the destination is obtained. The content of this process itself may be the same as the process that the congestion avoiding route providing unit 56 obtains the congestion avoiding route. In the congestion avoiding route providing unit 56, the current time is the start of movement, whereas in the predicted congestion avoiding route providing unit 57, the departure date / time estimated from the departure date / time or arrival date / time specified in the predicted route search request is moved. It is the start time.

  As described above, when the congestion level at the departure date / time is obtained based on the past congestion record, the predicted congestion avoiding route providing unit 57 sets the route having the minimum congestion level as the predicted congestion avoiding route. Ask.

  However, for example, when an event is started at the arrival date and time at the destination, many users may issue a predicted route search request with the event holding location as the destination and the event start date and time as the arrival date and time. In this case, based on the past results alone, the traffic volume of the person who intends to move to the event location is not reflected when the predicted congestion avoidance route is obtained. Therefore, in this embodiment, the degree of congestion at the date and time to be searched is determined by taking into account not only the past congestion record but also the traffic volume predicted in the future by analyzing the search history information. I asked for it more accurately. Note that when using the search history information, the number of search history information is the number of searches and not necessarily the number of people who actually move. Therefore, the degree of congestion of each route is calculated with a smaller weight than the congestion history information. It is better to do so.

  In this way, among the routes from the departure point to the destination, the degree of congestion of each route at the time of departure is calculated considering both the degree of congestion based on the past and the degree of congestion based on the predicted traffic volume in the future. Then, a route having the smallest congestion degree is obtained as a predicted congestion avoiding route from the routes (step 112).

  When the predicted congestion avoidance route is obtained, the predicted congestion avoidance route providing unit 57 provides the predicted congestion avoidance route to the request transmission source user (step 113). As a providing method, as in the case of the congestion avoiding route, it may be provided by character information or image information.

  As described above, the predicted congestion avoiding route providing unit 57 identifies the identification information (user ID) and name of the user who issued the predicted route search request, the starting point, the destination, and the starting point specified in the predicted route searching request. The search history information is generated by adding the date and time when the predicted route search request is accepted to the date and time or arrival date and time, and is registered in the search history information storage unit 65 (step 114).

  If the received information transmission request is not a predicted route search request (N in step 110), an error indicating the fact is notified to the user that information not to be processed in the present embodiment has been received (step 110). 115).

  Incidentally, in the processing described with reference to FIG. 9, various information is provided in response to a request from the user, but the congestion information management server 50 according to the present embodiment further has an automatic distribution function. In order to realize the automatic distribution function, first, the information management unit 59 displays an automatic distribution setting screen (not shown) on the PC 5 or 7 or the mobile phone 6 used by the user according to a predetermined operation from a user who desires automatic distribution. , 8 and the automatic delivery information is set through the screen. Then, automatic distribution information as exemplified in FIG. 8 is set for each user.

  The information distribution unit 58 always compares the distribution date and time of the automatic distribution information registered in the automatic distribution information storage unit 68 with the current date and time, and the current date and time match the distribution date and time set in the automatic distribution information. When doing so, the congestion information providing unit 54 or the congestion avoiding route providing unit 56 that provides the information set in the distribution target information is instructed to transmit the congestion information or the congestion avoiding route to the corresponding distribution destination. Alternatively, the information distribution unit 58 may receive the information to be transmitted from the congestion information providing unit 54 or the congestion avoiding route providing unit 56 and distribute it to a specified distribution destination.
