Description

  The present invention, for example, guides a sightseeing guide on a sightseeing bus or a pleasure boat to a target sightseeing point based on other navigation such as GPS and autonomous navigation using a direction sensor (for example, a gyro sensor) and a vehicle speed sensor / acceleration sensor. The present invention relates to an automatic guide system that is automatically executed at the time of the operation.

Conventionally, in the case of a sightseeing guide on a sightseeing bus or a pleasure boat, it is generally carried out by a guide attendant, but has the following problems.
(1) It is not possible to deal with passengers in different languages.
(2) Visual supplementary data such as old scenery of sightseeing points cannot be disclosed, and even if it can, it cannot be done in a timely manner.
(3) Since the guide attendant is in a standing posture, it is difficult to ensure safety against accidents and shocks during sudden braking.

  Therefore, guide contents are executed when a tourist point is reached by using a navigation system based on hybrid navigation, such as GPS, other navigation, direction sensor (for example, gyro sensor) and autonomous navigation using vehicle speed sensor / acceleration sensor. There can be seen an automatic guide system that eliminates the need for a guide attendant so that guidance based on image and voice guidance is started (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 11-337354 (see paragraph numbers [0002] and [0003])

  However, in the above prior art, the required time is determined simply by playing back image data and voice guidance, so the next sightseeing point may be reached on the way, unexpected traffic congestion or redness By getting caught in the signal, you will not guide anything until you reach the next sightseeing point after the guide ends, so you can not respond flexibly and can not execute the guide according to the progress situation etc. There was a problem that had to be done.

  The present invention is based on the above-described prior art, in view of the problem that it is not possible to execute a guide in accordance with the progress status, a navigation system that determines the current position of the moving means based on various position information, and the sightseeing points by video and audio guidance A system for executing content to be guided, the content execution system including a guide data storage unit storing content data for guiding tourist points with video and audio guidance, a display unit for video data, and audio An audio unit for reproducing guidance data; a determination means for determining whether a difference between the calculated value of the current position and the set value of the starting point of the sightseeing point content set on the course is within the set range; and within the set range Means to read and execute the corresponding content at the time, the set value of the content execution time and the actual And a means for editing the length of the content data based on the result of the collating means. The guide data storage unit stores content data files for all tourist points, and each content data The file has at least one content data, each content data is composed of a plurality of priority sentence data, each sentence data is composed of video data and audio guidance data, By combining sentence data according to the priority order and making it fit within the actual execution time, it is possible to cope with changes in the executable time of the content data depending on the progress status, and solve the above problems .

In short, the present invention includes a navigation system that determines the current position of the moving means based on various position information and the like, and a system that executes content that guides sightseeing points with video and audio guidance. A guide data storage unit storing content data for guiding points with video and audio guidance, a display unit for video data, an audio unit for reproducing audio guidance data, the calculated value of the current position and the course A means for determining whether or not the difference between the set values of the starting points of the tourist point contents within the set range, a means for reading and executing the corresponding content when the set point is within the set range, and setting the content execution time Value and actual value matching means, and the length of the content data based on the result of the matching means Content data files for all sightseeing points are stored in the guide data storage unit, each content data file has at least one content data, and each content data The sentence data is composed of a plurality of priority sentence data, each sentence data is composed of video data and voice guidance data, and the editing means combines the sentence data according to the priority order so as to fit in the actual execution time. Since this is done, it can be executed as content in accordance with the progress.
Also, it is well known to map-match vehicle position data on a route in a guide map based on not only GPS position information but also travel distance and gyro (direction sensor) data. In general GPS navigation systems, All roads must be covered, and the map matching process is complicated. However, when using the system of this application for a sightseeing bus, only the roads used as routes or the roads used as detour courses may be selected. Alternatively, if the matching process is performed by narrowing down to the roads that can be passed, it is possible to perform a simple and high-accuracy map matching process in which matching to an incorrect road hardly occurs.

  The voice guidance data is composed of a plurality of language data, and the voice guidance data is divided into each language data and outputted to the audio unit, and the contents based on each language data can be selected by the audio unit. Its practical effect is great, such as being able to deal with passengers.

It is a basic flowchart figure of the automatic guide system which concerns on this invention. It is a flowchart figure of the navigation system in an automatic guide system. FIG. 6 is a flowchart for switching screens in the automatic guide system. It is a flowchart figure of the priority edit of the content execution system in an automatic guide system.

It is a figure which shows the display state of the guide map whose advancing direction is reverse to Fig.8 (a). It is a figure which shows the display state of the guide map in the automatic guide system for ships.

  In the automatic guide system according to the present invention, as shown in FIG. 5, a navigation system for determining the coordinates of the current position X of a moving means such as a car or a ship equipped with the automatic guide system based on various position information. 1 and a system 2 that executes content based on video and audio guidance of tourist points A1, A2,.

As shown in FIGS. 5 and 6, the navigation system 1 includes a GPS (Global Positioning System) receiver, and simultaneously receives radio waves from a plurality of artificial satellites to obtain positioning data of the moving means. 3 and an autonomous positioning unit 4 that includes an autonomous sensor such as a direction sensor (gyro sensor), a vehicle speed sensor, and an acceleration sensor, and calculates the moving distance and moving direction of the moving means from the output data of the autonomous sensor, and the GPS And means for calculating the coordinates of the current position X of the moving means based on output data from the unit 3 and the autonomous positioning unit 4.
In the navigation system 1, the map data storage unit 5 stores map data for displaying a guide course and an assumed detour course as a guide map M on the display unit 7 to be described later if necessary. It is preferable to display the current position X on the course of the guide map M displayed on the display unit 7 to be described later as shown in FIGS.

  In the content execution system 2, as shown in FIGS. 5 and 6, a guide data storage unit 6 storing content for guiding sightseeing points A 1, A 2,. Display unit 7, audio unit 8 for reproducing voice guidance data, set values of content starting points P1, P2,... Set on the course to guide the calculated value of the current position X and sightseeing points A1, A2,. Means for determining whether or not the difference between the two values is within the setting range, means for reading and executing the corresponding content when the difference is within the setting range, means for comparing the set value of the content execution time and the actual value, and the matching means And a means for editing the length of the content data based on the result.

  As shown in FIG. 6, the arithmetic processing in the navigation system and the reading / executing means, the collating means, and the editing means in the content execution system are performed by one system PC 9, and various data are stored in the system PC9. Storage means, a graphic board to which the display unit 7 is connected, a 5.1ch sound board to which the audio unit 8 is connected, and a switch unit having a start button and an end button is connected thereto. It is preferable that the storage medium 10 be detachable from the system PC 9.

As shown in FIGS. 6 and 7, the map data storage unit 5 in the navigation system 1 and the guide data storage unit 6 in the content execution system 2 are a storage medium 10 to be mounted on the system PC 9, more specifically, the system PC9. Is set in the USB memory 10 to be attached to the storage medium connector in FIG. 1, and a predetermined area in the single USB memory 10 is allocated as the map data storage unit 5 and the guide data storage unit 6, and further various calculation values and measurement values, etc. A log data storage unit 11 for storing log data consisting of may be allocated.
Therefore, if a dedicated USB memory 10 is created for each sightseeing course, it is possible to easily cope with changes in the sightseeing course simply by replacing the USB memory 10.

As shown in FIG. 7, the guide data storage unit 6 stores data files CF1, CF2,... For executing a plurality of contents, and each content data file CF1, CF2,. Has a plurality of content data CD1, CD2,... In order to be able to cope with a change in the content of the voice guidance depending on the approach direction to the content, and each of the content data CD1, CD2,. The sentence data SD1, SD2,... Are composed of video data and voice guidance data.
The sentence data SD1 with the first priority is created so as to be surely stored within the shortest time when the next sightseeing point A1, A2,... Flows smoothly. SD2, SD3,... Are executed after being edited so as to be integrated into one sentence from the higher priority in the sentence data SD1 so as to be within the required time, or executed while editing.
The voice guidance data is composed of a plurality of language data so as to be compatible with multiple languages, and is set so as to simultaneously execute the multilingual data together with the video data.

  Further, in each content data file CF1, CF2,..., In addition to the content data CD1, CD2,..., Auxiliary content data SC (for example, sandwiched between the next sightseeing points after the sentence data with the lowest priority is completed) , Commercial video data) may be stored.

  For example, as shown in FIGS. 8A and 8B, the sightseeing points A1, A2, and A3 on the route are located on the left side in the order of the sightseeing points A1, A2, and A3 when traveling from the left direction. However, when proceeding from the opposite right direction, the tourist points A3, A2, and A1 are positioned on the right side in this order, so the content data files CF1, CF2, and CF3 of the tourist points A1, A2, and A3 are located. Are provided with at least two types of content data CD1 and CD2, and specifically, the beginning of the voice guidance in the content data CD1 is “Looks right” and the beginning of the voice guidance in the content data CD2. Sentence data SD1 is created so that “I can see on the left is ~”.

  Although not shown, the display unit 7 may use two monitors to display a guide map M and content video on the one hand and a bus guide video (actual image or CG) on the other hand. The video may be a moving image that indicates the direction of each content by hand, and the bus guide character itself may be changed according to the content.

The audio section 8 has a function capable of simultaneously reproducing multilingual voice guidance separately. For example, each seat has a channel and an earphone plug, and a plurality of programs can be switched by the channel. If the multi-channel audio system that can be distributed to the existing system is already used, the language is selected by switching the channel so that the channel can be selected. 5.1ch sound board is connected with FM / AM transmitter and wireless transmitter 12 such as infrared, light or various radio wave transmitters, and each passenger receives for example FM radio, PDA (Personal Digital Assistant). Lending terminal 13, for example, radio transmitter 12 as FM transmitter and receiving terminal 13 as FM radio In this case, a language is allocated for each frequency so that the voice guidance can be heard by matching the frequency of the desired language.
In short, it is only necessary that the receiving terminal 13 that receives the multilingual data transmitted from the wireless transmitter 12 can be selected.

In the automatic guide program in the automatic guide system according to the present invention, basically, the current position X of the moving means is calculated based on the data from the GPS unit 3 and the autonomous positioning unit 4, and the required time is calculated. A navigation program for displaying the guide map M and the current position X of the moving means on the screen as necessary, and an execution program for the content data CF1, CF2,.
Further, the automatic guide program storage unit 14 may be set in the USB memory 10, the navigation program and the content execution program are stored in the automatic guide program storage unit 14, and the USB memory 10 is used as a storage medium. When it is attached to the connector, the program data is output to the system PC 9 side.

Then, in order to execute the automatic guide program having the navigation program and the content data execution program by the system PC 9, when the start button is pressed and the automatic guide system according to the present invention is started, as shown in FIG. 3 and the output data output from the autonomous positioning unit 4 as needed are subjected to arithmetic processing (including map matching processing as correction processing) by the navigation program, and the current position X on the course of the moving means during movement If the content is not being executed, the current position X is displayed on the course in the guide map M displayed on the display unit 7, and the arithmetic processing by the navigation program is performed separately even when the content is being executed. Continue to be.
Therefore, as shown in FIG. 3, when the start button is pressed, a guide map M in which the current position X is aligned on the course is displayed on the display unit 7, and when the content is executed, the screen of the display unit 7 becomes a content video. When the content is switched and the content is finished, the arithmetic processing by the navigation program is continued to be executed separately even during the content execution, and therefore, the content is immediately switched to the guide map M again.

  In the content execution program, as shown in FIG. 1, when the start button is pressed, the calculated value of the current position X by the calculation process by the navigation program is compared with the set value, and the difference is within the set range. When the event occurs, the corresponding content is determined, the content data is read and executed after confirming that there is no executed flag, and the content data files CF1 and CF2 storing the executed content data are stored. An executed flag is set in ... and this processing information is written to a log file.

Further, when executing the content, in order to perform the “priority editing” process as shown in FIG. 4, the corresponding content data CD1, CD2,... In the content data files CF1, CF2,. When there is no “all sentence completion command” in the content data CD1, CD2,..., The video data and the voice guidance data in the first sentence file SD1 with the highest priority are executed, and at the same time, the actual value of the content execution time It is determined whether or not the next sentence can be executed by “course data verification” that checks the set value. If it is not possible, the content is terminated. If all the sentences are not completed, the sentence being executed is determined. Sentence data SD2, SD of the priority order after the end of The video data and voice guidance data in ... are continuously executed, and the processing after “course data verification” is executed in the same manner as described above. If possible and all sentences have been completed, the presence or absence of auxiliary content data SC is confirmed. If there is a grace period for execution with “Yes”, the auxiliary content is executed. If there is no grace period for execution with “Yes”, or if the auxiliary content data SC is “None” in the first place, the content is terminated.
In addition, even if there is an all sentence completion command for the read content data CD1, CD2,..., The sentence data SD1, SD2,... Are executed in order from the highest priority, but “course data collation” is not performed. If an “event occurs” during execution, execution of the next content is put on hold, the content being executed is continued as it is, and the next corresponding content is executed in the same manner as described above after the completion.

Therefore, for example, even if the travel means is a sightseeing bus and the course direction is unavoidably changed and the approach direction to the sightseeing points A1, A2,... Is changed, a plurality of content data CD1, CD2,. Therefore, the corresponding content data CD1, CD2,... Are selected and executed, but the progress status is determined at any time by “course data verification” that compares the measured value of the required time with the set value, and the execution time is determined according to the result. Is executed after performing “priority editing” processing for assembling sentence data SD1, SD2,... In order of priority so as to be within the execution time.
Alternatively, sentences arranged in descending order of priority are sequentially executed, and in the process, the road conditions are judged by “course data comparison” that compares the measured value of the required time with the set value. As a result, all sentences are executed. If it is determined that the content cannot be executed, the content is terminated when the executable sentence is completed.
If it is determined that all sentences have been executed, and a certain amount of time remains until the next content is executed, auxiliary content such as a commercial video is inserted.

  In other words, sentences are executed in descending order of priority, but the content length is set in advance from the overall progress from the start of the guide and edited so that it actually fits within the section (between adjacent tourist points). There is a method that edits whether to execute the next sentence in the process of executing the upper sentence, grasping the progress status by actually measuring the required time and comparing it with the set value. If it is possible to perform “priority editing” processing that compares the set value of the required time with the calculated value and “course data collation” processing that edits the content to the actual execution time length based on the result For example, the present invention is not limited to the above method.

  However, even if it is determined that all sentences cannot be executed, the content may be continuously executed without being interrupted. Specifically, the content execution start point is reached during the content execution. However, it is also possible to define that the next content is to be executed after the content has been completely finished and the content execution is continued as it is.

  Then, by setting the executed flag to the content data files CF1, CF2,... In which the executed contents are stored, the current position X of the moving means is started again at the sightseeing points A1, A2,. Even if it is calculated that the points P1, P2,... Have been reached, since the execution flag is processed as “present”, the execution of the corresponding content is rejected so that it is not repeatedly executed.

  In some of the plurality of sightseeing points A1, A2,..., The passenger may be lowered and the engine may be stopped. However, the sightseeing guide does not end unless the end button is pressed, and an automatic guide system is provided when the engine is restarted. Also, the guide map M is displayed on the display unit 7 by the navigation program, and the current position X is displayed on the course. If necessary, the log data is checked to see how far it has been completed.

Although the target of the moving means in the automatic guide system is a car such as a sightseeing bus,
Even if it is a ship, the configuration is substantially the same, but when the planned route L is displayed on the guide map M and the output data output from the GPS unit 3 and the autonomous positioning unit 4 at any time is processed by the navigation program. The correction processing of the current position X is not map matching, but the average value of the calculated values is calculated and displayed as the wake La and the predicted route Lb is displayed, but the calculated value based on the data from the GPS unit 3 is allowed. If the value exceeds the range, the value is excluded as an abnormal value and the average value is calculated.

  Ships are equipped with AIS (Automatic Identification System) as standard equipment, and each AIS is equipped with VHF digital radio equipment dedicated to each ship. Automatically exchanges information on ship-to-ship and ship-to-land facilities by automatically transmitting and receiving identification numbers, ship names, types, positions, courses, speed, navigational conditions, and other safety information to land facilities such as centers. Since this is a system, using this data, as shown in FIG. 9, the current positions Y1, Y2,... Of the ship in the area that can be displayed on the display unit 7 are displayed on the guide map M together with various information. ing.
