If the guidance start time is set when the schedule is input (YES), the wireless terminal 100 ends the schedule registration process. If there is no setting in step 208 (NO), the wireless terminal 100 acquires the departure time of the route information acquired in step 207 (S209). The wireless terminal 100 sets the guidance start time 2 hours before the departure time (S210), and ends the schedule registration process.
It should be noted that the guidance start time set in step 210 can be changed as necessary depending on how many hours or minutes before the time acquired in step 209.

  In addition, when it is determined that the current position acquired in S204 is the same as the destination, it may have a function of generating an alarm sound without performing route search.

  With reference to FIG. 11, the processing flow of the route search processing will be described. The route search process is a process from transmitting the search route information to the route search server 3 from the wireless terminal 100 and determining the cheapest route information received from the route search server 3 as the guide route. The flow starts when the generation of the search route information to be transmitted to the route search server 3 is completed.

  In FIG. 11, the wireless terminal 100 first transmits search route information to the route search server (S301). The wireless terminal 100 receives the route information in S302, compares the departure time of the received route information with the current time of the GPS information, and if there is an available route or the arrival time of the received route information and the start of the schedule Times are compared and an analysis is made as to whether there is a route in time (S302). If the suspended route is stored in the failure information of the failure information storage unit 114 in S303, the wireless terminal 100 excludes the route information that uses the route (S303). The wireless terminal 100 determines whether there is a route in time for the arrival time (S304). If YES, the wireless terminal 100 determines the cheapest route with the shortest required time from the route information in time, stores it (S305), and ends.

  In the present embodiment, the route selection information is described so that the wireless terminal 100 automatically selects the cheapest route selection information, but the present application is not limited to this. User selection based on user operation detection, time priority, or distance priority may be used. Further, a plurality of searched guide route information is simultaneously monitored, the position of each guide route information is monitored from GPS information (current position, current time), and an alarm is notified at the start time or scheduled time, respectively. May be.

  When NO in step 304, the wireless terminal 100 emits an alarm sound notifying that there is no route in time for the arrival time (S306). The wireless terminal 100 determines whether an operation has been received when it is not in time for the arrival time but guidance to the destination is required (S307). When the determination is NO, the wireless terminal 100 ends as it is.

  If it is determined in step 307 that guidance to the destination is necessary (YES), the wireless terminal 100 acquires GPS information (S308). The wireless terminal 100 generates search route information using the current position, the current time, and the destination 73 of the schedule table 70 (S309). The wireless terminal 100 transmits the generated search route information to the route search server 3 (S310). The wireless terminal 100 receives the route information (S311). The wireless terminal 100 determines the cheapest route with the shortest required time from the received route information as a guide route, stores it (S312), and ends.

  With reference to FIG. 12, a processing flow when a failure occurs on the guidance route and the route must be changed will be described. This flow is started when the operation information management server 4 is accessed and it is determined that there is a failure on the guide route.

  The wireless terminal 100 identifies a section where the failure information and the guidance route match (S501). The wireless terminal 100 determines whether the failure information is delayed or suspended (S502). When there is a delay (YES), the wireless terminal 100 obtains a timetable such as a station or a bus stop in the delay section, and stores a result obtained by adding the delay time to each timetable (S503). The wireless terminal 100 generates search route information in which the current position is the departure place and the schedule destination and start time are set to the destination and arrival time, respectively (S504). The wireless terminal 100 transmits the generated search route information to the route search server 3 (S505). The wireless terminal 100 receives and analyzes the route information from the route search server 3 as a response to the search route information in step 505 (S506). The wireless terminal 100 determines whether there is a route in time for the arrival time in the received route information (S507). If there is a route in time (YES), the wireless terminal 100 determines and stores the cheapest route with the shortest required time as a guide route (S508), and ends.

  When there is no route in time in Step 507 (NO) and when it is determined in Step 502 that the failure is suspended (NO), the wireless terminal 100 stores the failed section as a suspended section (S509). The wireless terminal 100 generates search route information using the current position, current time, and schedule destination (S510). The wireless terminal 100 performs route search processing using the generated search route information (S511) and ends.

  With reference to FIG. 13, the guidance processing flow of the wireless terminal 100 will be described. This flow starts after setting the schedule.

  The wireless terminal 100 waits for the guidance start time (S401). At the guidance time (YES), the wireless terminal 100 extracts a guidance route from the guidance route storage unit 115 (S402). The wireless terminal 100 acquires operation information and compares it with the guidance route (S403). The wireless terminal 100 determines whether there is a failure such as a timetable disturbance or traffic jam on the guidance route (S404). If it is determined that a failure has occurred (YES), the wireless terminal 100 identifies the transportation means with the failure and the state of the failure (delay, suspension, etc.) and stores them in the failure information storage unit 114 (S405). The wireless terminal 100 performs route change processing (S406). The wireless terminal 100 determines whether there is a guidance route (S407). If there is (YES) and there is no failure in step 404 (NO), the wireless terminal 100 issues an alarm sound (departure guidance) (S408). When there is no guide route in step 407 (NO), the wireless terminal 100 ends because there is no route in time for the arrival time due to a failure. Note that the alarm notification process when there is no route in time for the arrival time due to a failure is included in step 406.

  After step 408, the wireless terminal 100 acquires GPS information and analyzes the current position and the current time (S409). With respect to the acquired current time, the wireless terminal 100 determines whether it is five minutes before the transfer point departure (S410). When YES in step 410, the wireless terminal 100 acquires operation information and compares it with the guide route (S411). The time of 5 minutes in step 410 can be changed as necessary.

  The wireless terminal 100 determines whether there is a failure on the guide route (S412). If it is determined that there is not (NO), the wireless terminal 100 emits an alarm sound informing the departure (S413). If it is determined in step 412 that there is a failure (YES), the wireless terminal 100 specifies and updates the failure information (S414). The wireless terminal 100 performs route change processing (S415). The wireless terminal 100 determines whether there is a guidance route (S416). When YES, the wireless terminal 100 informs the user about the guidance route change by issuing an alarm sound (S417). If there is no guide route in step 416 (NO), there is no route in time for the arrival time due to a failure, and the wireless terminal 100 ends. Note that alarm notification processing when there is no route in time for the arrival time due to a failure is included in step 415.

  When step 410 is NO, after step 413 or step 417, the wireless terminal 100 compares the current position with the guide route in step 418 and determines whether the user is moving on the guide route. When it is determined that the route is out of the guide route (NO), the wireless terminal 100 sets the schedule start time, the current position, and the schedule destination to the arrival time of the schedule table 70, the current position of the GPS information, and the schedule table 70, respectively. The search route information set in the destination 73 is generated (S419). The wireless terminal 100 performs route search processing (S420). The wireless terminal 100 determines whether there is a guide route (S421). If there is (YES), the wireless terminal 100 issues a change guide with an alarm sound (S422). If it is not step 421 (NO), since there is no route in time for the arrival time due to a failure, the wireless terminal 100 ends. Note that the alarm notification process when there is no route in time for the arrival time due to a failure is included in step 422.

  When moving on the guide route in step 418 (YES) or after step 422, the wireless terminal 100 determines whether or not the current position is the destination (S423). If it is determined that the destination is the destination (YES), the wireless terminal 100 emits an alarm sound informing the destination arrival (S424). The wireless terminal 100 deletes the stored failure information (S425). The wireless terminal 100 displays confirmation of return route guidance (S426). The wireless terminal 100 waits for a user operation for a certain period (S427). When the operation is performed as necessary by the user (YES), the wireless terminal 100 uses the schedule / start time to the end time 72 in the schedule table 70 as the departure time, and the destination 73 in the schedule table 7 as the departure place. The searched route information is generated (S428). Note that the return destination may be different from the departure point 82 of the route information 80, so that the return destination is automatically set based on the departure point 82 and the destination 83 of the route information in addition to being set manually. You may do it.

  The wireless terminal 100 executes route search processing (S429) and ends. When NO in step 427, the wireless terminal 100 ends as it is. If the destination is not determined in step 423 (NO), the wireless terminal 100 returns to step 409 and repeats the processing from step 409 to step 423 until the destination is reached.

  Suppose that there is a development schedule meeting at Company A from 8:00 to 12:00 on January X, and the user leaves the house on that day and wants to receive guidance from 6:00 on January X. In such a case, the user uses the operation keys 101 to input a schedule schedule, start time, end time, and destination. It is not essential to enter the guidance start time and the guidance start location. If not entered, the wireless terminal 100 automatically sets the current position acquired from the GPS information as the guidance start location and 2 hours before the departure time of the guidance route as the guidance start time. The time of 2 hours before the guidance start time is automatically set can be changed as necessary. The radio terminal 100 stores the input / set schedule information. Next, the wireless terminal 100 transmits to the route search server 3 the search route information that is automatically set to the arrival time as the schedule start time, the schedule guidance start location as the departure location, and the schedule destination as the destination. Receive route information. The wireless terminal 100 stores the cheapest route with the shortest required time from the received route information as a guide route. Here, it is assumed that the route as shown in FIG. 5A is determined as the guide route.

  The wireless terminal 100 receives the operation information at the guidance start time and checks whether there are any obstacles such as delay or suspension on the guidance route. The fault information obtained at this time is stored as shown in FIG. According to this table, there is no obstacle on the guide route until 6:50 which is the departure time of the guide route acquired first, and when it becomes 6:50, the wireless terminal 100 emits an alarm sound for prompting departure. The wireless terminal 100 always acquires GPS information during movement and determines whether the current position is on the guidance route or has arrived at the destination. When it is 5 minutes before the departure from the transfer point, the wireless terminal 100 acquires operation information of each means of transportation and checks whether a failure has occurred on the guide route. Here, when the departure time is 7:05, which is 5 minutes before the departure time of the bus stop A, it is found that a delay of 30 minutes has occurred in the bus bound for XX line △ as shown in FIG. And When the delay occurs, the wireless terminal 100 obtains the timetables of all stations and bus stops in the use section (here, from the bus stop A to the station a), and adds the delay time. In this case, the bus stop timetable from bus stop A to station a is obtained, and 30 minutes is added to each. Using the time table added with 30 minutes, the radio terminal 100 searches for a route, and if there is a route in time for the arrival time, the cheapest route is selected as the guide route. If there is no route that is in time, the route is treated as suspended, and the wireless terminal 100 checks whether there is a route in time by excluding route information including the suspended route when performing a route search again. Here, although the bus is delayed by 30 minutes, the time table of FIG. 6B is created by adding the delay time to the time table of bus stop A shown in FIG. 6A, and the bus that should have arrived at 6:40 is 7 : 10 arrived at bus stop A, and after that, it was able to arrive at company A as originally planned without any obstacles.

  When arriving at the destination, the wireless terminal 100 displays a screen asking whether or not return route guidance is necessary. If an operation requiring route guidance is performed, the wireless terminal 100 automatically sets the schedule end time 12:00 as the departure time, the schedule destination company A as the departure point, and sets the destination in-house. The search route information set in is generated and route search is performed. Note that the return destination can be set in advance as an initial value. If return route guidance is required, operation information is always acquired even if the guidance start time is not reached. The return route was originally decided to use the subway XX line up, but when the operation information was acquired at 9:00, it was in the situation of having to stop driving in the section from B station to D station Is detected. It is assumed that this section is on the guidance route and has not been restored even when 12:00 which is the guidance start time for the return trip is reached. In such a case, the wireless terminal 100 stores the failure information storage unit 114 from the B station to the D station as a suspended section. The wireless terminal 100 acquires GPS information and performs a route search using the current position, current time, and destination as search conditions. The wireless terminal 100 excludes the route including the suspended section from the acquired route information, and determines the cheapest route with the short required time from the remaining routes as the guide route. Here, the route detouring via station C shown in FIG. 5B is determined as the guide route. As a result, the route information in the guide route storage unit in FIG. 8 is updated. Upon arrival at the company, the failure information is deleted from the failure information storage unit 114, and the route guidance for this schedule is terminated.

  Next, when the user cannot leave home at 6:50 for some reason, the wireless terminal 100 determines that the current position is not on the guidance route based on the GPS information. The wireless terminal 100 generates search route information in which the schedule start time is set as the arrival time, the current position is set as the departure point, and the schedule destination is set as the destination, and route search is performed. The wireless terminal 100 determines the guide route in FIG. 5C and issues an alarm sound informing the route change. The guide route determined here takes less time than the guide route of FIG. 5A, but is expensive. In this way, even if the departure time is delayed or the route is deviated from the guidance route, the wireless terminal 100 continues to update the information as long as there is a route in time from the position / time to the start time of the schedule. In this case as well, an alarm sound is emitted when the departure time is 7:00. When there is no route in time for the start time of the schedule, the wireless terminal 100 issues an alarm sound (schedule error) notifying that the guide route has been lost. The user is not in time for the arrival time, but can receive route guidance in consideration of operation information to the destination if necessary.
