[First Embodiment]
The alerting system of the present invention can be implemented in various ways.
FIG. 1 is an overall configuration diagram when the present invention is implemented as a network-type alert system owned by a user. The alerting system 10 of this embodiment includes a route search system 20 that searches for an optimal route of transportation such as trains, buses, and airplanes, a weather information provision system 30 that provides weather information, and an operation failure that provides operation failure information. It is configured to be connected to the providing system 40 via a communication line N1 such as the Internet.

First, an external system connected to the alerting system 10 will be described.
[Route search system]
The route search system 20 is based on a Web server, and has a data communication interface 21, a search condition setting unit 22, a route search engine 23, and an operation information DB (DB is a DB) that performs bidirectional communication with the alerting system 10. Abbreviation of database, the same shall apply hereinafter).

  The route search condition setting unit 22 includes a route search engine 23 based on one of the departure point and destination sent from the alerting system 10 and any one of transit points, departure times and arrival times, or a combination thereof. Set the search condition. When the route search engine 23 receives the set search condition, the route search engine 23 searches for the next station or stop with the lowest route operation cost based on the operation information including the route and timetable stored in the operation information DB 24. By repeating the processing in a chain, the optimum route candidate according to the route search condition is specified. Then, the identified optimal route candidate is returned to the alerting system 10 via the data communication interface 21 and the communication line N1. “Operating cost” usually covers the time required for operation, but it can also cover distance, fare, and combinations thereof. As the basic function part of the route search engine 23, for example, the route search software “Electric Spa” (registered trademark) provided by the present applicant can be used.

[Meteorological information provision system]
The weather information providing system 30 also has a Web server as a basic configuration, and includes a data communication interface 31 that performs bidirectional communication with the alerting system 10 and a weather information DB 31. In the weather information DB, weather information such as current weather and weather forecasts throughout the country are recorded together with symbols or symbols representing the contents, and when an information request with a place name and time zone is received, the time Weather information corresponding to the belt and place name is transmitted to the information requesting source (for example, the alerting system 10). In some cases, voice information is added, or the voice information is provided only. In this case, the voice information is provided in a fixed form.

[Operating obstacle provision system]
The operation failure information providing system 40 notifies the alerting system 10 of text information indicating the contents together with a symbol or symbol indicating the cause when an operation failure reason such as a vehicle failure or an accident for each route occurs. It is like that. The text information for each operation failure reason may be accumulated, and the accumulated information may be accessed from the alerting system 10. In some cases, voice information is added, or the voice information is provided only. In this case, the voice information is provided in a fixed form.

[Awareness system]
Next, the alerting system 10 of this embodiment will be described in detail.
The alerting system 10 is owned by a user, and can be realized by cooperation of a storage device such as a hard disk device, a display device, a sound output device, a computer having a communication function, and an alerting processing program. In the present embodiment, a registration processor (database is abbreviated as “DB”) M1 is built in the storage device by the computer processor executing the alert program, and the computer is connected to the main controller 11 and the timer 12. , The recognition processing unit 13, the communication control unit 14, the input control unit 15, the sound control unit 16, and the display control unit 17.

The registration DBM1 stores a forward condition table M100, a search condition table M110, and a set time table M120.
The advance condition table M100 defines a condition for advancing the time to call attention, that is, an operation delay reason for determining whether or not the advance condition is met, and how much the operation delay event is advanced. The advance time is recorded together with the identification information of the reason for the delay in operation. In the search condition table M110, the route search conditions set by the user and input to the route search system 20 are recorded together with the user identification information.
In the set time table M120, for example, search start time, arousal time, scheduled departure time, and estimated arrival time are recorded for each destination. These recorded contents will be described in detail later.

  The timekeeping unit 12 is a clock mechanism for measuring the current time, and transmits the measurement result to the main control unit 11 through the internal bus B1. When the input information is speech information, the recognition processing unit 13 converts the speech information into standard text information using, for example, a natural language recognition tool. The voice information is sent from the weather information providing system 30 or the operation failure information providing system 40. If the text information is not a fixed phrase, the recognition processing unit 13 changes the text information to a fixed sentence. The communication control unit 14 performs communication control among the route search system 20, the weather information providing system 30, and the operation failure information providing system 40.

  The input control unit 15 receives data input by a user who operates the input device K1 such as a keyboard, and registers what is to be registered in each table M100 to M120 of the registration DBM1 in cooperation with the main control unit 11, Other than the above, control for transmission to the main control unit 11 is performed. The sound control unit 16 performs sound output control to the speaker SP1 according to an instruction from the main control unit 11. The display control unit 17 performs display control of information on the display device according to an instruction from the main control unit 11.

  The main control unit 11 comprehensively controls the reading and writing of information to the functional blocks 11 to 17 and the registration DBM 1 described above, and performs various controls or processes for executing the arousing information providing process, such as time monitoring, menus, etc. Display, recognition of acquired information, advance condition setting, time registration, route search instruction, and the like. These control or processing procedures will be described later.

[Operation]
Next, an operation example of the alerting system 10 configured as described above will be described.
After receiving registration or setting of various conditions by a user who wants to receive a service, the alert system 10 monitors the current time and the occurrence of an operation delay reason (a reason that meets the advance condition). If a reason that matches the advance condition is not detected, control information is generated at the awakening time set by the user. On the other hand, if a reason that meets the advance condition is detected, control information is generated at a time that complies with the advance condition. . And based on this control information, a corresponding functional block is controlled so that predetermined alert information is output. “Advance condition” refers to a condition for performing a process for advancing the output time of alert information for alerting the user.

First, the advance condition setting process will be described. The advance condition may be set in advance so as to be common to all users on the system side, but here, it is assumed that the user can individually set according to his / her circumstances. To do.
FIG. 2 is a processing procedure diagram for setting the advance condition.
When the advance condition setting is selected by the user, the main control unit 11 controls the display control unit 17 to display a menu on the display device D1 (step R101). What is displayed is the type of weather that delays the operation time, such as earthquake, heavy rain / snow, heavy fog, etc., operation delay reasons other than natural phenomena such as accidents, vehicle failures, etc., and the advance time set for each event It is an input screen. When the user operates the input device K1 to select and input corresponding information, the input control unit 15 registers the registration DBM1 in the advance condition table M100 (steps R102 and R103).

  An example of the contents of the advance condition table M100 registered in this way is shown in FIG. In the advance condition table M100, the type of delay reason and the advance time are registered in the field identified by the automatically assigned ID. For example, an ID of “001” is 10 minutes ahead of the weather 1 (eg, heavy fog), an ID of “002” is 20 minutes of the weather 2 (eg, heavy rain or snow), and an ID of “003” is the weather 3 ( For example, 30 minutes is set for an earthquake. The same applies to other IDs.

Next, time registration processing will be described. FIG. 3 is a processing procedure diagram of time registration processing.
When a registration process such as time is selected by the user, the main control unit 11 controls the display control unit 17 to display a menu on the display device D1 (step R201). What is displayed is the arousal time indicating how early the awakening information should be output from the scheduled departure time, departure place (departure station or registered departure place name), and transit point (via station or registered destination name) The destination (the destination station or the registered destination name), the scheduled departure time or the estimated arrival time, and a selection screen for selecting whether these conditions are repeated once or every day. Set tag information to repeat daily. The awakening time is, for example, a time such as “30 minutes before the scheduled departure time”.

  When the user operates the input device K1 and inputs corresponding information, the input control unit 15 receives the information and temporarily stores it in a cache memory (not shown) (step R202). “Scheduled departure time” and “scheduled arrival time” are normally only “scheduled departure time”, but if it is desired to prioritize the scheduled arrival time, only that time can be used. Further, if the starting point and the destination are known, a minimum route search is possible, and the transit point may be omitted.

  Upon receiving all the information from the user, the main control unit 11 outputs the received departure place and destination (or waypoint) and scheduled departure time (or estimated arrival time) to the route search system 20 to search for a route. Is executed. When the search result is received, the display control unit 17 is controlled to display the search result on the display device (step R203). The search result is a plurality of route candidates. These route candidates are displayed in order of the lowest cost (for example, the minimum required time), and wait for any one selection by the user (step R204: No). When one of the route candidates is selected by the user through the input device K1, it is handled as the optimum route (step R104: Yes). Then, the scheduled departure time and the estimated arrival time of the optimum route are specified, the arousal time is specified by adding the above-mentioned arousal time to the scheduled departure time, and further, the advancing time is set in the advance condition table M100. The search start time is calculated by advancing the time obtained by adding several minutes to the maximum advance time (step R205).

  For example, when the scheduled departure time of the optimal route scheduled to reach 10:00 is 8:30, the awakening time is 30 minutes (that is, the awakening time is 8:00), and the maximum advance time is 30 minutes ( The time at this time is 7:30), and 7:25, which is 5 minutes earlier, is calculated as the search start time. When moving forward for a plurality of routes, the above procedure is repeated.

  The main control unit 11 registers the departure point, waypoint, and destination in the search condition table M110, and sets the search start time, arousal time, scheduled departure time, and scheduled arrival time. Register with M120.

An example of the contents of the search condition table M110 registered in this way is shown in FIG. 6, and an example of the contents of the set time table M120 is shown in FIG.
Referring to FIG. 6, in the search condition table M110, the departure point, the waypoint, and the destination are registered in the field identified by the automatically assigned ID. For example, in the field of ID “101”, the departure place “Koenji”, the transit place “Shinjuku”, and the destination “Mita (Tokyo)” are registered. The departure place “Koenji” is also registered after ID “102”. Note that the transit point may be omitted.

  The set time table M120 can be registered by departure place or destination. FIG. 7 is an example of the set time table M120 for each destination. In the illustrated example, the destination ID is automatically assigned, and the search start time, the awakening time, the scheduled departure time, and the estimated arrival time are registered in the field identified by the destination ID. When registering by departure place, the destination ID is replaced with the departure place ID.

[Arousing information provision processing]
Next, arousal information provision processing will be described. The awakening information provision process is executed by the main control unit 11 based on the advance condition table M100, the search condition table M110, and the time setting table M120.
FIG. 4 is a procedure explanatory diagram of the alerting process by the main control unit 11.
When the main control unit 11 detects that the search start time registered in the set time table M120 (the earliest time when a plurality of times are registered) is reached based on the measurement result of the time measuring unit 12 ( Step S101: Yes), weather information (such as the type of weather) is acquired from the weather information providing system 30 for an area related to any of the departure point, the waypoint, and the destination, and the area from the operation failure information providing system 40 Check whether there is operation failure information in. If it exists, the information is acquired (step S102). If the acquired weather information or operation trouble information is not a fixed sentence, the recognition processing unit 13 is activated as appropriate to convert the information content into a fixed sentence of the text.

  The main control unit 11 determines whether or not the acquired information matches a condition registered in advance in the advance condition table M100 by the fixed sentence recognition process (step S103). If they do not match, it is determined that there is no accident in normal weather conditions, and the arrival of the arousal time registered in the set time table M120 is awaited (steps S103: No, S104). On the other hand, if the acquired information matches the conditions registered in the advance condition table M100, the search conditions registered in the search condition table M110 are transmitted to the route search system 20, and the route search is immediately started. (Step S103: Yes, S105). The search condition to be transmitted is the search condition set as the highest priority when a plurality of search conditions are registered, but other search conditions may also be included.

  When the search result of the optimum route based on the search condition is acquired (step S106), at the latest, only the advance time (for example, 30 minutes) registered in the advance condition table M100 from the estimated arrival time registered in the set time table M120. A time difference between the scheduled departure time of the route arriving before the earlier time and the scheduled departure time of the currently searched optimum route is calculated (step S107). It is checked whether or not time adjustment is necessary. If necessary, the awakening time is advanced (step S108).

  For example, the originally registered operation route is an operation route identified by the ID “101” in FIG. 6 and having “Koenji” as the departure point and “Mita (Tokyo)” as the destination. As shown, the information acquired at the search start time registered is 10:00, the scheduled departure time is 8:30, the arousal time is 8:00, and the search start time is 7:25. When it matches with “weather 3” in the condition table M100, the advance time is 30 minutes. Since the estimated arrival time that is advanced by the advance time is 9:30 at the latest, the route that arrives at the destination earlier than that is scheduled to arrive at the latest scheduled arrival time, for example, 9:28. Identify the path of. Then, it is checked how much the scheduled departure time of the identified route is earlier than the scheduled departure time (8:30) currently registered in the set time table M120. For example, if the time difference from the scheduled departure time of the route arriving at 9:28 is 32 minutes, the registered arousal time (8:00) is advanced by 32 minutes, and the arousal time (7:28) ) Temporarily.

When the main control unit 11 detects that it has reached the early call time (7:28), it makes sound information (warning sound) by sound from the speaker SP1, or visually information from the display device. Control information for outputting (message) is generated, and the control information is output to the sound control unit 16 or the display control unit 17.
In addition, when an operation trouble reason is not detected, the said control information is produced | generated and output at the original call time (8:00) (step S111).

  As a result, if there is a delay in operation, the pre-registered awakening time is advanced to search for the route, and as a result, the awakening information is output at a time when one or more trains, buses, etc. can be used. Therefore, the user can surely arrive by the scheduled arrival time at the destination registered in advance even if there is a change in the operation status such as weather or train.

[Second Embodiment]
In the first embodiment, an example in which a computer with a communication function owned and operated by a user is operated as the alerting system 10, but the alerting system of the present invention is an extension of the route search system 20 described above. It can also be realized as a function. In this case, the user only needs to have a mobile phone or his / her personal computer (PC) capable of outputting the alert information. Hereinafter, an exemplary embodiment in this case will be described.

  FIG. 8 is an overall configuration diagram of the alerting system of the second embodiment. This alerting system 50 is realized by a web server equipped with a storage device reading and executing an alerting program. In this embodiment, the Web server is operated as the main control unit 51, the time measuring unit 52, the recognition processing unit 53, the data communication interface 54, the search condition setting unit 55, and the route search engine 56, and the storage device stores the registered DBM2 and Build an operation information DB.

  In comparison with the first embodiment, the timing unit 52 is the timing unit 12, the recognition processing unit 53 is the recognition processing unit 13, the search condition setting unit 55 is the search condition setting unit 22, the route search engine 56 is the route search engine 23, and the operation. The information DB 57 corresponds to the operation information DB 24, and the registration DBM2 corresponds to the registration DBM1. That is, it has the same function and handles the same information.

  The weather information providing system 30 and the operation failure information providing system 40 are the same as those in the first embodiment. The communication line N2 corresponds to the communication line N1 of the first embodiment.

  The PC 60a or the mobile phone 60b operated by the user has a function of performing data communication with the alerting system 50, a browser function, and an alerting information output function. These functions can be used as they are as standard equipment of the PC 60a or the mobile phone 60b.

  In the alert system 50 of the second embodiment, the data communication interface 54 provides a browser screen for setting conditions to the PC 60a and the mobile phone 60b, respectively, and information input from the browser screen is stored in the registration DBM2. While registering, the above-mentioned alert information is output to the PC 60a and the mobile phone 60b. The main control unit 51 is different from the first embodiment in that control is performed for that purpose. In the case of the mobile phone 60b, the alerting information can be an attached warning sound or vibration. This awakening information is generated by the control information described above.

[Modification]
In the alerting systems 10 and 50 of the present invention, when a route in which the delay cause specified by the weather information providing system 30 and the operation failure information providing system 40 can be specified, the route along with the alerting information at the alerting time. The information that the operation delay has occurred may be provided. In this way, it is possible to provide information that causes a delay in operation and give the user a margin for taking the next best measure.
Alternatively, a search condition for performing a route search that excludes the specified route may be created, and thereby the above-described alert processing may be performed by searching for a route that bypasses the route.

A computer program that functions as a computer program. A computer with a storage device connected
A communication means for communicating between a user terminal operated by a user and an external system providing information indicating an operation delay reason;
Advance search for each delay event that affects operation time, route search conditions including departure and destination, scheduled departure time, arousal time earlier than the scheduled departure time, and start of search that arrives even earlier than the alert time Storage means for storing time in the storage device;
Clock mechanism that measures the current time;
Route search means for searching for a route between the departure point and the destination;
When the time measured by the clock mechanism reaches the search start time, information indicating an operation delay reason that is known at the scheduled departure time is acquired from the external system, and the acquired information is the registered delay reason. If it matches, if it departs from the departure place at the scheduled departure time, it will reach the destination more than the advance time stored for the delay reason than the time when it should arrive at the destination The route search means searches for a new operation route that arrives at the destination by the time, and the time that exceeds the time difference between the new scheduled departure time specified by the received search result and the scheduled departure time. Control means for outputting predetermined alert information to the user terminal at a time earlier than the alert time;
A computer program that functions as a computer program.
