Description

  The present invention relates to a route guidance system, a route guidance device, and a route guidance program for guiding a route from a departure point to a destination for a user, and in particular, a route guidance system for performing guidance such as departure time and transfer of a route to be guided. The present invention relates to a route guidance device and a route guidance program.

  Currently, navigation technology that provides route guidance from the departure point to the destination is realized by using a dedicated device such as a car navigation system or by incorporating dedicated software in a mobile terminal such as a mobile phone. Yes.

  However, the conventional technology has a problem that a dedicated device or a compatible terminal in which software can be incorporated is required, and there is a problem that it cannot be used when it is not desired to incorporate a device or software that does not have these functions. In recent years, with the development of network technology, information is frequently exchanged by electronic mail, and terminals having an electronic mail transmission / reception function are widely spread. Therefore, it is very convenient if route guidance (navigation) can be performed by sending and receiving general electronic mail.

  Although different from the navigation technique, Patent Document 1 (Japanese Patent Laid-Open No. 2000-285045) describes a technique for sending an e-mail in which a search statement is described on a homepage at a specific address and obtaining a response by a reply e-mail. ing. Moreover, in a search site that exists on the Internet, it is possible to execute a route search from the boarding station to the getting-off station by inputting “from the boarding station to the getting-off station” as a search sentence (Non-patent Document 1). reference). Therefore, by combining these, there is a possibility that a technique for transmitting an e-mail in which a search sentence “from the boarding station to the getting-off station” is input and receiving the route search result by e-mail may be realized.

In some cases (when the subject is “Re˜” and the route search result is quoted in the text, that is, in the case of a re-search instruction format), it is an instruction to re-search another route under the same route search condition. Determine.

  Also, in FIG. 3F, the received mail discriminating unit 22a of the first embodiment refers to the subject and text, and the received e-mail is compared with the e-mail of the route search result transmitted by the first mail transmitting unit 24. If the reply mail has been deleted (when the subject is "Re ~" and the text is blank, that is, in the route guidance non-execution mode), the route that has been searched is deleted and the route guidance is not executed. Determine that there is.

  The route guidance time setting unit 22b sets the time for performing route guidance based on the route search result (see FIG. 3B) transmitted by the first e-mail transmission unit 24. In FIG. 3B, the route guidance time setting means 22b according to the first embodiment first determines each time of the departure point of the searched route, the boarding station (matches the departure point in the first embodiment), the transfer station, the departure station, and the destination. Is extracted as the guide time. That is, in FIG. 3B, “15:37”, “15:45”, “15:51”, “15:54”, and “16:04” are extracted as the guide times. Then, three minutes before each time is set as a guide mail transmission time (route guide execution time) at which route guide mail is transmitted and route guidance is performed.

FIG. 4 is an explanatory diagram of an e-mail queue created by the route guidance system according to the first embodiment.
The route guidance mail creating means 22c is sent to the user by the second email sending means 25 at each guidance mail sending time based on the route search result (see FIG. 3B) sent by the first email sending means 24. E-mail (route guidance mail). In FIG. 4, the route guidance mail creating means 22c of the first embodiment extracts the guidance time and the portion of the guidance content corresponding to the guidance time from the route search result, and sends the user's email address (user1 @ yyy. ne.jp), subject information (guidance time, boarding station (or transfer station), route, etc.), text in the route search conditions in order of the route (that is, the contents of the subject line of the route search result email ( An e-mail in which “see FIG. 3B)” is created at every guide mail transmission time.

  In FIG. 2, the queue management means 22d is a queue in which the guidance mail transmission time set by the route guidance time setting means 22b and the guidance mail created by the route guidance mail creation means 22c are arranged in the order of the guidance mail transmission time.

There is a queue deletion means for deleting the guidance mail transmitted by the mail transmission means 25 and for which the route guidance has been executed, or for deleting the queue by the cancellation or non-execution of the route guidance. In the first embodiment, a queue is created for each route to be guided.

In FIG. 2, the route guidance time discriminating means 22e discriminates whether or not the guidance mail transmission time has come based on the current time and the guidance mail transmission time stored in the queue.
The route guidance non-execution means 22f is configured not to perform route guidance when an e-mail in the route guidance non-execution mode (see FIG. 3F) is received. The route guidance non-execution unit 22f according to the first embodiment deletes the guide mail transmission time and the guide mail queue created based on the corresponding route search conditions with reference to the text field of the email stored in the queue. By doing so, the guide mail is not transmitted and the route guidance is not executed.

  The route guidance canceling unit 22g cancels the route guidance being executed when receiving the route guidance cancellation style (see FIG. 3D) e-mail. The route guidance canceling means 22g according to the first embodiment refers to the column of the body of the email stored in the queue and deletes the guidance email transmission time and the guidance email queue created based on the corresponding route search conditions. Thus, the route guidance is stopped so that the guide mail is not transmitted.

  The route re-search means 22h executes route re-search when an e-mail in a re-search instruction format (see FIG. 3E) is received. When the order of the route of the received e-mail is “first route”, the route re-search means 22h according to the first embodiment first deletes the queue such as the guide mail of the first route and sets the route search condition to the next. The route search condition is output to the route search means 23 by adding a condition of “second route” which is the order of the routes.

(Description of processing of mobile phone 1)
FIG. 5 is a flowchart of route guidance processing provided in the route guidance server of the route guidance system according to the first embodiment.
Each ST (step) process in the flowchart of FIG. 5 is performed according to a route guidance program stored in a ROM or the like of the route guidance server 9. This process is executed in parallel with other various processes of the route guidance server 9.
The flowchart shown in FIG. 5 is started when the route guidance program is started.

In ST1 of FIG. 5, it is determined whether or not an e-mail has been received. If yes (Y), the process proceeds to ST2. If no (N), the process proceeds to ST13.
In ST2, it is determined whether or not the subject of the received electronic mail is a reply, that is, whether or not “Re” is included at the beginning of the subject. If yes (Y) (in the case of a new route search request), the process proceeds to ST3, and if no (N), the process proceeds to ST8.
In ST3, a route search corresponding to the route search condition described in the text of the received electronic mail is executed. Then, the process proceeds to ST4.

In ST4, the search result is transmitted to the user by e-mail by the first e-mail transmission means 24. Then, the process proceeds to ST5.
In ST5, the guidance time is extracted based on the search result. Then, the process proceeds to ST6.
In ST6, 3 minutes before each guidance time extracted in ST5 is set as the guidance mail transmission time. Then, the process proceeds to ST7.
In ST7, based on the search result, a guide mail for each guide time is created, and a guide mail queue is created and stored. Then, the process returns to ST1.

In ST8, it is determined whether or not a text is described in the received electronic mail. If yes (Y), the process proceeds to ST9, and if no (N) (in the case of the route guidance non-execution style), the process proceeds to ST12.
In ST9, it is determined whether or not the search result transmitted by the first email transmission means 24 is included in the body of the received email. If yes (Y) (in the case of the re-search instruction form), the process proceeds to ST10, and if no (N) (in the case of the route guidance cancellation form), the process proceeds to ST12.

In ST10, the guide mail queue created based on the previous route search result is deleted. Then, the process proceeds to ST11.
In ST11, the search for the next route is executed based on the route search condition described in the subject of the e-mail for which the re-search instruction has been given. Then, the process proceeds to ST4.
In ST12, since the route guidance is instructed not to be executed or cancelled, the corresponding guide mail is referred to by referring to the subject of the received e-mail (in the case of canceling route guidance) or the text (in the case of not instructing route guidance). Delete the queue. Then, the process returns to ST1.

In ST13, it is determined whether or not the guide mail transmission time has come by referring to the queue. If yes (Y), the process proceeds to ST14. If no (N), the process returns to ST1.
In ST14, the second e-mail transmission means 25 transmits a guidance e-mail that has reached the e-mail transmission time. Then, the process proceeds to ST15.
In ST15, the guide mail transmitted in ST14 is deleted from the queue. Then, the process returns to ST1.

(Operation of Example 1)
6 is a sequence diagram of the route guidance system according to the first embodiment, FIG. 6A is a sequence diagram during normal route guidance processing, FIG. 6B is a sequence diagram when route guidance is stopped during route guidance, and FIG. 6C is a route diagram. FIG. 6D is a sequence diagram when canceling the route guidance of the searched route.
In the route guidance system S according to the first embodiment having the above-described configuration, when a user transmits a route search request e-mail (see FIG. 3A) from the mobile phone 1 to the route search server 9, the route search server 9 performs route search. The route search result is promptly returned by e-mail (see FIG. 3B).

At this time, the route search server 9 creates a queue composed of the guide mail transmission time and the guide mail based on the route search result. When the guide mail transmission time (when used) is reached, the guide mail (see FIG. 3C) is sequentially sent. It is transmitted to the user's mobile phone 1.
When the user requests a route search again, a reply email (see FIG. 3E) quoting the text of the route search result is sent to the route search result email (see FIG. 3B). Then, the route search is performed again. Therefore, the search result of the re-searched route can be immediately received by electronic mail, and the guide mail of the route re-searched at the time of use is distributed.

Furthermore, if you do not want to receive route guidance that you have searched for due to a change in the user's schedule or an input error in the search conditions, leave the text blank for the route search result email (see FIG. 3B). By sending the reply mail (see FIG. 3F), route guidance non-execution (cancellation) can be instructed.
In addition, if the user wants to cancel the route guidance on the way by changing the destination or getting on a later vehicle while receiving the route guidance, a reply email to the guidance email (see FIG. 3C) Can be instructed to cancel route guidance.

  Therefore, the route guidance system S according to the first embodiment allows a user to make a route search request using widely-distributed e-mail without installing dedicated software or preparing a dedicated device. The result can be immediately received by e-mail. Moreover, the capital investment of the provider who provides the route guidance service can be suppressed.

  In addition, since e-mails are distributed sequentially according to the guide time (riding time, transfer time, getting off time) searched by route search, the user simply refers to the e-mails that are sequentially transmitted at the time of use. You can receive route guidance service. Therefore, even when the interval from the time when the route search is requested to the time of use is open, it is possible to eliminate the trouble of searching for the route search result e-mail. Even if multiple route search results have been received, you can receive route guidance by referring to the guide mail sent when using it. You can prevent getting into the engine.

Furthermore, in the route guidance system S according to the first embodiment, since the e-mail is transmitted 3 minutes before the actual boarding time and transfer time, the user can recognize transfer and getting off in advance.
Also, since the guidance mail distributed during the route guidance has the route guidance in the subject field, the route guidance can be obtained by simply referring to the subject without scrolling the display of the e-mail and referring to the text. It is easy for the user to grasp the route guidance. In particular, a cellular phone having a function of displaying a subject on a display unit for a predetermined time when receiving an e-mail can receive route guidance without shifting to an e-mail browsing screen.
Furthermore, simply by sending a reply mail to the received electronic mail, it is possible to instruct re-search, cancel route guidance, or cancel in the middle of route guidance, so various instructions can be given with a simple operation method.

Next, the route guidance system according to the second embodiment of the present invention will be described. In the description of the second embodiment, the same reference numerals are given to the components corresponding to the components of the first embodiment, and the details thereof will be described. The detailed explanation is omitted.
The second embodiment is different from the first embodiment in the following points, but is configured in the same manner as the first embodiment in other points.

FIG. 7 is a block diagram (functional block diagram) illustrating functions of the route guidance system according to the second embodiment, and corresponds to FIG. 2 according to the first embodiment.
In FIG. 7, in the route guidance system of the second embodiment, there is no route guidance cancellation style compared to the case of the first embodiment, and the re-search instruction style is the same as the route guidance suspension style in the first embodiment. Yes. Therefore, in the route guidance unit 22 ′ of the route guidance server 9 of the second embodiment, the received mail discriminating unit 22a ′ refers to the subject (title) and body of the received email and the email is a request for route search. Or whether it is a request for re-searching, an instruction to stop route guidance halfway (route guidance stop instruction), or an instruction to request execution of route guidance (route guidance execution instruction) .

FIG. 8 is an explanatory diagram of an electronic mail transmitted and received in the route guidance system of the second embodiment, FIG. 8A is an explanatory diagram of an electronic mail in a route guidance execution instruction format, and FIG. 8B is an explanatory diagram of an additional schedule guidance email. .
That is, the received mail discriminating means 22a ′ of the second embodiment refers to the subject and the text, and the received e-mail quotes the text from the route search result e-mail sent by the first mail sending means 24. Route reply (see FIG. 8A) (when the subject is “Re˜” and the route search result is quoted in the text, that is, in the route guidance execution instruction format), the route guidance of the searched route It is determined that this is an instruction requesting execution of.

Accordingly, the route guidance time setting unit 22b, the route guidance mail creation unit 22c, and the queue management unit 22d according to the second embodiment set the guidance email transmission time and create the guidance email when the route guidance execution instruction is given. Execute queue creation.
Further, the route guidance unit 22 ′ according to the second embodiment has the route guidance non-execution unit 22f according to the first embodiment omitted, and includes a route search result storage unit 22i and an additional schedule presence / absence determination unit 22j.
The route search result storage unit 22 i stores the route search result searched by the route search unit 23.

  The additional schedule presence / absence determining unit 22j determines whether or not the received route guidance execution instruction style email has a schedule (route guidance) added to the route search result transmitted by the first email transmission unit 24. Is determined. That is, in FIG. 3B and FIG. 8A, in response to the route search result (see FIG. 3B) transmitted by the first electronic mail transmission means 24, the user returns “16: When the description of the schedule addition form “00 company call” is added, the added part is determined as an additional schedule. If there is an additional schedule, the route guidance time setting means 22b sets the time specified in the additional schedule as the guidance mail transmission time, and the route guidance mail creation means 22c uses the text of the additional schedule as the subject. A guide mail (see FIG. 8B) is created.

(Explanation of flowchart of embodiment 2)
Next, although the flowchart of Example 2 is demonstrated, about the process similar to Example 1, the same ST number is attached | subjected and detailed description is abbreviate | omitted.
FIG. 9 is a flowchart of the route guidance process of the route guidance system according to the second embodiment, and corresponds to FIG. 5 according to the first embodiment.
In FIG. 9, the same processing as ST1 to ST4 and ST13 to ST15 of the route guidance processing of the first embodiment shown in FIG. 5 is executed. When the processing of ST4 is performed, the processing proceeds to ST21. If so, proceed to ST22.
In ST21, the route search result by the route search means 23 is stored. Then, the process returns to ST1.

In ST22, it is determined whether or not a text is described in the received electronic mail. If no (N) (in the case of a re-search instruction format), the process proceeds to ST23, and if yes (Y), the process proceeds to ST24.
In ST23, the search for the next route is executed based on the route search condition described in the subject of the e-mail instructed to re-search. Then, the process proceeds to ST4, returns to ST1 through the process of ST21.
In ST24, it is determined whether or not the search result transmitted by the first e-mail transmission means 24 is included in the body of the received e-mail. If yes (Y) (in the case of the route guidance execution instruction style), the process proceeds to ST5. If no (N) (in the case of the route guidance cancellation style), the process proceeds to ST12 and returns to ST1.

Next, the processes of ST5 to ST7 are executed, and the process proceeds to ST26.
In ST26, the received route guidance execution instruction style e-mail is compared with the stored route search result to determine whether or not there is an additional schedule. If yes (Y), the process proceeds to ST27. If no (N), the process returns to ST1.
In ST27, the guide time of the additional schedule is extracted, and the extracted guide time is set as the guide mail transmission time. Then, the process proceeds to ST28.
In ST28, an additional schedule guide mail is created and added to the queue. Then, the process returns to ST1.

(Operation of Example 2)
FIG. 10 is a sequence diagram of the route guidance system of the second embodiment corresponding to FIG. 6 of the first embodiment, FIG. 10A is a sequence diagram during normal route guidance processing, and FIG. 10B is a reply mail of a route guidance execution instruction transmitted. FIG. 10C is a sequence diagram when a route re-search is requested.
10, in the route guidance system S of the second embodiment having the above-described configuration, the user executes a route search request and transmits a route search result e-mail. A queue is created when the guidance server 9 receives the message (see FIG. 10A). Therefore, in the route guidance system S according to the second embodiment, unlike the first embodiment, even when the user executes a route search request and sends a route search result e-mail, a reply e-mail in the route guidance execution instruction format is received. Otherwise, the route guidance server 9 does not create an e-mail queue (see FIG. 10B). Further, in the case of a re-search instruction format with a blank text, a re-search is performed, and a queue is created when a reply mail in the route guidance execution instruction format for the re-search is received (see FIG. 10C).

  In the route guidance system S of the first embodiment, when a large number of fictitious route search requests are transmitted by a malicious person, a large amount of queues are created and a large amount of guidance mail is distributed, resulting in increased processing capacity. There is a risk that the system will puncture. On the other hand, in the route guidance system S according to the second embodiment, a queue is not created unless a reply mail instructing execution of route guidance is transmitted. Therefore, in the route guidance system S according to the second embodiment, the addition of the system can be reduced, and the occurrence of puncture of the system against a malicious attack can be reduced.

  Further, in the route guidance system S of the second embodiment, since a route guidance execution instruction can be performed by a simple operation of a reply mail that quotes a route search result, it is easy for the user to use. Furthermore, when creating a reply mail in the route guidance execution instruction format, a schedule that the user wants to add can be added, and the guide mail of the additional schedule can be received at the guide time, improving convenience.

Next, the route guidance system according to the third embodiment of the present invention will be described. In the description of the third embodiment, the same reference numerals are given to the components corresponding to the components of the first and second embodiments, and the details thereof will be described. The detailed explanation is omitted.
The third embodiment is different from the first and second embodiments in the following points, but is configured in the same manner as the second embodiment in other points.

FIG. 11 is a block diagram (functional block diagram) illustrating the function of the route guidance system according to the third embodiment, and corresponds to FIG. 7 according to the second embodiment.
In FIG. 11, in the route guidance system S of the third embodiment, the route guidance unit 22 ″ of the route guidance server 9 includes a plurality of route presence / absence discriminating units 22k in addition to the functional units of the route guidance unit 22 ′ of the second embodiment. And a guidance period duplication determination means 22m.

  The multiple route presence / absence determining means 22k determines whether or not there is a route (first route) different from the route (second route) for which the guide time has already been set. That is, it is determined whether or not the same user is set to execute a plurality of route guidance. When there is a route guidance execution instruction, the multiple route presence / absence determining unit 22k according to the third embodiment transmits the transmission mail address of the user of the e-mail for which the route guidance execution instruction has been issued and the guide mail registered in each queue. It is determined whether or not there are a plurality of guide routes by comparing with the transmission mail address of the user of the transmission destination to determine whether or not there is a queue having the same mail address.

  The guidance period duplication determination means 22m is provided for a route (second route) already registered within a plurality of guidance time periods set for a route (first route) for which guidance time is newly set. It is determined whether or not some of the plurality of route guidance times are included. In other words, the guidance period duplication determination unit 22m of the third embodiment performs a period between the first time and the last time of the guide mail transmission time registered (stored) in the queue, and a guide that is newly extracted and set. It is determined whether or not the period between the first time and the last time of the mail transmission time overlaps. In the third embodiment, when the periods overlap, the first e-mail transmission unit 24 automatically transmits a duplicate notification mail notifying the user that there are overlapping periods.

(Description of Flowchart of Example 3)
Next, the flowchart of the third embodiment will be described. The same processing as in the first and second embodiments is denoted by the same ST number, and detailed description thereof is omitted.
FIG. 12 is a flowchart of the route guidance process of the route guidance system according to the third embodiment, and corresponds to FIG. 9 according to the second embodiment.
12, in the route guidance process of the third embodiment, the following ST31 to ST34 are executed between the processes of ST5 and ST6 in the route guidance process of the second embodiment.

In ST31, it is determined whether or not there is a queue in which the same e-mail address as the e-mail transmission e-mail address of the route guidance execution instruction format is registered. If yes (Y), the process proceeds to ST32. If no (N), the process proceeds to ST6.
In ST32, it is determined whether or not there is a guide time included in a period between the first guide time and the last guide time registered in the queue among the guide times extracted in ST5. If yes (Y), the process proceeds to ST33, and, if no (N), the process proceeds to ST6.
In ST33, it is determined whether or not there is a guide time registered in a queue included in a period between the first guide time and the last guide time extracted in ST5. If yes (Y), the process proceeds to ST34, and, if no (N), the process proceeds to ST6.
In ST34, a duplicate notification mail is transmitted to the user. Then, the process returns to ST1.

(Operation of Example 3)
FIG. 13 is a sequence diagram of the route guidance system of the third embodiment corresponding to FIG. 10 of the second embodiment. FIG. 13A is a sequence diagram in the case where the route guidance cannot be performed due to overlapping periods of route guidance, and FIG. FIG. 10 is a sequence diagram in a case where route guidance can be performed although periods for performing route guidance overlap.
In FIG. 13, in the route guidance system S of the third embodiment having the above configuration, when there are a plurality of route search requests from the same user (same email address), the times of the route to be guided overlap. If there is no route, each route can be guided. However, it is impossible in reality that the guide times overlap in one route and the other route and the route guidance of the two routes is simultaneously performed in parallel. Therefore, in the route guidance system S of the third embodiment, when two routes overlap, a route search request and a route guidance execution instruction are later notified to the user that they are duplicated. The queue is not created (see FIG. 13A).

  On the other hand, when the route guidance period of the other route is all included in one route guidance period and there is no guidance time of one route guidance within the other route guidance period (in case of No (N) in ST33) (See) Since route guidance for two routes is not parallel, route guidance is possible. Therefore, in this case, a queue is created for the other route, and route guidance is executed (see FIG. 13B). For example, it is possible to deal with a case where a detailed travel route search at a business trip destination is performed after a long distance travel route search by a business trip is performed.

  Therefore, in the route guidance system S according to the third embodiment, it is possible to prevent a plurality of route guidance, which is not possible as a real problem, from being mixed and performed at the same time, and to avoid the user itself being confused. it can. Further, when a large number of route searches and route guidance execution instructions are issued from the same mail address by a malicious person, it is possible to prevent a queue from being created and the processing speed from decreasing.

(Example of change)
As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to the said Example, A various change is performed within the range of the summary of this invention described in the claim. It is possible.

  In the above embodiment, the server side has one e-mail address. However, the present invention is not limited to this. The e-mail address of the e-mail transmitted by the first e-mail transmission unit 24 and the second e-mail are not limited thereto. It is also possible to set the e-mail address of the e-mail transmitted by the transmission means 25 to a different address. In this case, it is possible to easily determine whether the user is an email as a route search result or an email as route guidance.

Furthermore, in the embodiment, a mobile phone is exemplified as a terminal. However, the present invention is not limited to this, and any terminal can be used as long as it is a terminal capable of sending and receiving electronic mail. For example, the present invention can be applied to a PDA (Personal Digital Assistance), a personal computer, or a portable music player with a built-in electronic mail transmission / reception function.
In the embodiment, the format of the e-mail transmitted and received is not limited to the format illustrated in the embodiment, and any format can be adopted. Along with this, the contents described in the subject and text are not limited to the contents exemplified in the embodiment, and can be appropriately changed according to the design of the style and the determination method in the route guidance server 9. In addition, when an e-mail that does not conform to each format is received, an e-mail that notifies the user of the e-mail can be transmitted.

Furthermore, in the embodiment, the guide mail transmission time is set to 3 minutes before the guide time, but is not limited to this, and the guide mail transmission time is set to coincide with the guide time, set to an arbitrary time (2 minutes before, etc.) It can be set, or can be set as the departure time of the station in front of the transfer station, or can be arbitrarily changed.
In addition, in the embodiment, when the route guidance mail is transmitted, for example, an e-mail of an advertisement for a store in or near the transfer station can be transmitted or described in the guidance mail. In addition, an e-mail is sent only when the waiting time at the transfer station is long, or when the waiting time is short, it is an advertisement for a magazine department, and when the waiting time is long, it is used as an advertisement for a coffee shop or restaurant. It is also possible to change the content of the e-mail to be transmitted according to the waiting time.

Further, in the third embodiment, when the route overlaps, it is set not to create a guide mail of the route searched for later, but the present invention is not limited to this, and a reply from the user to the duplicate notification email is made. Based on this, it is possible to configure either one of the routes to be selectable, or to delete both.
In the embodiment, it is desirable to create a route guidance mail and register it in the queue. However, the present invention is not limited to this, and only the route guidance time is extracted and transmitted when the route guidance time comes.
