FIG. 1 is a block diagram showing a configuration example of a navigation system to which the present invention is applied. The navigation system consists of application function parts,
An interface (I / I / I) that exchanges data and scripts with the general-purpose processing unit and an external device (not shown)
F) Unit 14 (receiving means, transmitting means). In the application function part, CCD (Char
The ge Coupled Device (camera) unit 1 is configured to output a video signal corresponding to a predetermined image. The image format generation unit 2 formats and outputs the video signal supplied from the CCD unit 1 according to a predetermined rule.

The display unit 3 (icon display means) displays a predetermined image or character, and displays an icon, a cursor, and a mark of a predetermined shape, which will be described later. The microphone unit 4 inputs a predetermined sound and outputs a corresponding sound signal. The A / D unit 5 converts an analog audio signal supplied from the microphone unit 4 into a digital audio signal and outputs the digital audio signal.

The D / A unit 6 converts a digital audio signal into an analog audio signal. The speaker section 7 outputs a sound corresponding to the analog sound signal supplied from the D / A section 6.

The position data acquisition unit 8 is provided with, for example, a plurality of G
By receiving a radio wave from a PS (Global Positioning System) satellite and performing a predetermined calculation, the current position is acquired and corresponding position data is output. The electronic map data storage unit 9 stores predetermined map data and outputs the map data as needed.

In the general-purpose processing section, the operation unit 10 is composed of, for example, a keyboard, a joystick, a touch panel, or the like, and is capable of instructing a predetermined operation and inputting predetermined data, script, and the like. . The CPU (Central Processing Unit) 11
It operates according to an application program stored in the memory 12 described later, and executes various processes.

The memory 12 stores application programs and instructions and data required when the CPU 11 executes various processes. The storage memory 13 stores data such as a script library described later. This storage memory 13
Can be realized by a recording medium such as a semiconductor memory and an optical disk.

Via an interface (I / F) unit 14, for example, IEEE-488 (GPIB (General
rpose Interface Bus)) and other parallel signals, RS23
A method of performing communication using a serial signal such as 2C is conceivable, but it is only necessary to be able to perform bidirectional communication. Also, connection with an external device (not shown) may be made by wire (for example, a flat cable, a pin jack, a plug, or the like) or wirelessly (for example, radio wave, infrared, or the like).

As described above, this navigation system not only displays a map on the display unit 3 and guides the user to a destination, but also includes the CCD unit 1 and the microphone unit 4 to capture an image of a predetermined subject. , A predetermined voice can be recorded.

FIG. 2 is a diagram showing a configuration example of software (interpreter) for sequentially interpreting and executing a script. The script library 22 is a collection of functions written in a script, and is stored in the storage memory 13 according to the script, or is called from the storage memory 13 and used.

The syntax / semantic analysis unit 21 (interpretation means)
A sentence described by a script input from an external device is read via the / F unit 14, and syntax analysis is performed by checking whether the sentence is not out of a prescribed syntax rule. Further, semantic analysis described later is performed. Has been made. Here, the data format of the script can be any of a binary code and an ASCII code (character string). However, since the script is described in ASCII code, in the case of binary code, ASCII
It is necessary to convert to I code.

If there is no error in the sentence as a result of the syntax analysis, the sentence is passed to the execution processing unit 23 (execution means). Therefore, the grammar of the script depends on the syntax rules described above. Whether the unit of a sentence sent from the syntax / semantic analysis unit 21 to the execution processing unit 23 is a single sentence or a compound sentence depends on the execution processing unit 23 side.

The execution processing unit 23 executes a sentence according to a predetermined rule. However, the control depending on the system is not directly executed, but is performed via the operating system 26.

The data area 24 stores a token (reserved word, identifier, etc.) table for executing a script, constants, variables, and the like. The library 25 depends on a system such as input / output processing.
A program such as a device driver for directly controlling hardware is stored.

An output form (data format, etc.) for outputting the result of executing the script by the execution processing unit 23
Is not particularly limited.

Further, the navigation program 27
This is a program for operating the original functions of the navigation system.

FIG. 3 is a diagram showing a specific example of a script. For the sake of explanation, the condition judgment statement is “if (execution condition)
It is assumed that "then (executable sentence) endif" and the repetition sentence follow the grammar of "while (repeated condition) do (executable sentence) endwhile".

According to this grammar, the script shown in FIG. 3 executes a process of “outputting a predetermined message when the time is XXXXX when the latitude / longitude is XXXXXX”. Represents. Also, the script shown in FIG. 4 states that "the process of saving latitude and longitude and saving the year, month, day, hour, minute, and second is repeated every time ◇◇ time elapses, until" ◇◇ time ". Indicates processing. Further, the script illustrated in FIG. 5 represents a process of “every time, the process of capturing an image and recording sound for a predetermined time is repeated.” However, in FIGS. 3 to 5, a character string “xxxx” contains a numeral representing an arbitrary latitude and longitude, and the character strings “xxxxxx” and “
It is assumed that “Δ” and “Δ” each include a numeral representing an arbitrary time or time.

The scripts shown in FIGS. 3 to 5 are examples, and various other processes can be described by the scripts. Further, by combining them, it is sufficiently possible to describe more complicated processing in a script.

FIG. 6 is a diagram showing a processing procedure from analyzing a script to executing the script. Here, as shown in FIG. 6A, it is assumed that a script corresponding to the script shown in FIG. 5 is input. That is,

If (time_b-time_a)> 60 then imp_picture () rec_voice () endif

The script (character string (AS)
The lexical analysis process is performed by the syntax / semantic analysis unit 21). That is, it is converted into a sequence of meaningful words (reserved words, identifiers, operators). These words are called tokens as described above, and the system holds them in advance in the data area 24 as a token table, and the syntax / semantic analysis unit 21 looks at the input script from the beginning, and stores it in the token table. If there is a matching token, it is recognized as a token.

Next, as shown in FIG.
The semantic analysis unit 21 performs a syntax analysis process. An analysis of whether or not the order in which words (tokens) appear in accordance with a prescribed grammar is performed by paying attention to reserved words in the word string (particularly, reserved words that appear first).

In this case, the first occurrence of the reserved word “i”
f "," then "appearing thereafter, and" endif "appearing thereafter form an if sentence, and" i "
f ”followed by“ (time_b-time_a)> 60 ”
Is recognized as an expression, and "inp_picture ()"
Is recognized as sentence 1 and “rec_voice ()” is recognized as sentence 2.

Next, as shown in FIG.
Based on the control structure (conditional branch, repetition processing, etc.) revealed by the syntax analysis in (b), the execution processing unit 23
Performs semantic analysis processing. In this case, the expression evaluation routine is called in accordance with the control structure of the if statement. First, the expression is evaluated. If the expression is “true”, then the processing routine of statement 1 is called and statement 1 is executed. Is done. In this case, a predetermined image is captured by the CCD unit 1 under the control of the CPU 11, and the captured image is recorded in the storage memory 13 or the like.

Thereafter, the processing routine for statement 2 is called and statement 2 is executed. In this case, under the control of the CPU 11, sound is input for a predetermined time by the microphone unit 4, converted into a digital signal by the A / D unit 5, and then recorded in the storage memory 13. On the other hand, if the expression is “false”, no processing is performed, and the process ends.

Next, as shown in FIG. 6D, the execution processing unit 23 executes, via the operating system 26, control depending on the system, for example, processing such as input / output and memory operation.

As described above, according to the script input through the I / F unit 14, the complex processing (a series of operations and procedures including conditions) described therein is automatically performed without user intervention. Can be executed.

FIG. 7 is a flowchart showing processing executed according to the script of FIG. First, in step S1, the position data acquisition unit 8 causes the position (latitude / latitude / position) of the vehicle (hereinafter abbreviated as “own vehicle”) to drive.
Longitude) is detected. This is performed by receiving radio waves from a plurality of GPS satellites and performing a predetermined calculation.
Next, in step S2, it is determined whether or not the latitude / longitude of the own vehicle is, for example, predetermined latitude x1, longitude y1.

If it is determined that the latitude / longitude of the vehicle is not the predetermined latitude x1, longitude y1, the flow returns to step S1, and
The processing after step S1 is repeatedly executed. on the other hand,
When it is determined that the latitude / longitude of the own vehicle is the predetermined latitude x1, longitude y1, the process proceeds to step S3, where a radio wave from a built-in clock circuit (not shown) or from a GPS satellite is received. By performing the process, the current time is obtained. Then, in step S4, the current time is
It is determined whether or not it is a predetermined time T1. If it is determined that the current time is not the predetermined time T1, the process returns to step S3, and the processes after step S3 are repeatedly executed. On the other hand, if it is determined that the current time is the predetermined time T1, the process proceeds to step S5, outputs a predetermined message, and ends the processing.

FIG. 8 shows an example of a process executed according to this script when “if time = XXXXX then” in the script shown in FIG. 3 is replaced with “if Δ △ elapsed time then”. It is a flowchart shown. First, in step S11, the position (latitude / longitude) of the vehicle is detected by the position data acquisition unit 8.
Next, in step S12, the latitude / longitude of the vehicle is
It is determined whether the latitude x2 and the longitude y2 are predetermined.
If it is determined that the latitude / longitude of the own vehicle is not the predetermined latitude x2 and longitude y2, the process returns to step S11, and the processes after step S11 are repeatedly executed. On the other hand, when it is determined that the latitude / longitude of the vehicle is the predetermined latitude x2, longitude y2, the process proceeds to step S13, and the current time is set as the reference time.

Next, the process proceeds to step S14, where the reference time is subtracted from the current time, and the result is set as the elapsed time.
Then, in step S15, it is determined whether or not the time T2 has elapsed. That is, it is determined whether the elapsed time is greater than or equal to the time T2. If it is determined that the time T2 has elapsed, the process proceeds to step S16,
The current time is set as the reference time, and a predetermined message is output in step S17. After that, the process returns to step S14, and the processes after step S14 are repeatedly executed.

On the other hand, if it is determined in step S15 that the time T2 has not yet elapsed, the process returns to step S14, and the processes in and after step S14 are repeatedly executed. In this manner, a predetermined message can be output at regular intervals.

FIG. 9 is a flowchart showing processing executed according to the script shown in FIG. First, in step S21, a processing time for performing the processing is set,
The current time is set as a reference time. Next, in step S22, the result obtained by adding the processing time to the current time is set as the end time.

In step S23, it is determined whether the current time is greater than or equal to the end time. If it is determined that the time is smaller than the end time, the process proceeds to step S24, and the time obtained by subtracting the reference time from the current time is set as the elapsed time. Then, the process proceeds to step S25, and it is determined whether or not a predetermined time T3 has elapsed. That is,
It is determined whether the elapsed time is greater than or equal to a predetermined time T3.

If it is determined that the predetermined time T3 has elapsed, the process proceeds to step S26, where the current time is set as the reference time, and in step S27, the latitude and longitude of the own vehicle are stored in the storage memory 13. Next, in step S28, the current year, month, day, hour, minute, and second are stored in the storage memory 13. If it is determined in step S25 that the time T3 has not yet elapsed, the process returns to step S23, and the processes in and after step S23 are repeatedly performed.

On the other hand, if it is determined in step S23 that the current time is greater than or equal to the end time, the process ends. In this manner, the traveling history of the own vehicle can be stored in the storage memory 13.

FIG. 10 is a flowchart showing processing executed according to the script shown in FIG. First, in step S31, the current time is set as a reference time. Next, in step S32, the result obtained by subtracting the reference time from the current time is set as the elapsed time. In step S33, it is determined whether or not a predetermined time T4 has elapsed from the reference time. When it is determined that the predetermined time T4 has elapsed, the process proceeds to step S34, and the current time is set as the reference time.

Next, in step S35, a predetermined image is taken in by the CCD unit 1, converted into a predetermined image format in the image format generation unit 2, and stored in the storage memory 13 or the like. In step S36, a predetermined sound is input for a predetermined time by the microphone unit 4 and is converted into digital data by the A / D unit 5, and is stored in the storage memory 13. Thereafter, the process returns to step S32, and the processes after step S32 are repeatedly executed.

On the other hand, if it is determined in step S33 that the predetermined time T4 has not yet elapsed, the process returns to step S32, and the processes in and after step S32 are repeatedly executed. In this way, the scenery and the like can be photographed at regular time intervals and stored in the storage memory 13 or the like.

These scripts can be registered in the script library 22 with a predetermined script name. For example, when a script as shown in FIG. 5 is defined by a script name camera (), the following is obtained.

Define camera () if (time_b-time_a)> 60 then imp_picture () rec_voice () endif endfunction

When this script "camera ()" is registered in the script library 22, if the script name "camera ()" is described in the script thereafter, the script registered under the script name "camera ()" It is read from the script library 22, interpreted and executed.

For example, the following script is described.

[0055]

When the script is supplied to the navigation system via the I / F 14, the script is interpreted by the syntax / semantic analysis unit 21 and "A + B <
When the condition "10" is satisfied, the script name ca
The script registered by mera () is called from the script library 22 and executed by the execution processing unit 23. In this way, frequently used scripts and the like can be registered in the script library 22 in advance. Thus, the user can reuse the created script, and can efficiently create the script.

Next, a script is made to correspond to the icon,
An example in which a script corresponding to the icon is executed will be described. This icon is displayed on the screen of the display unit 3. In the following, such an icon associated with a script will be appropriately referred to as a script icon. Also, "Execute script icon"
Means that a predetermined icon is selected and a script associated with the icon is executed. That is, by selecting a predetermined script icon, a script associated with the script icon can be executed.

Here, the selection of the script icon can be performed as follows. For example, a predetermined cursor is moved to a position where a desired script icon is displayed, and is superimposed on the script icon. As a result, the script icon is regarded as being selected. Alternatively, when a predetermined mark (for example, a mark indicating the position of the own vehicle described later) overlaps the script icon, it is considered that the script icon has been selected. In addition, based on the date and time information associated with the script icon and the current date and time, it is determined that the script icon has been selected at a predetermined timing.

FIG. 11 shows a script icon table in which a predetermined script is associated with each icon. The latitude and longitude indicate the position where the script icon is pasted on the map, and the year, month, day, hour, minute, and second indicate the date and time at which the script icon is or may be executed. The used icon address indicates an address on the storage memory 13 where the bitmap data of the used icon is stored, and the script is a script associated with the icon.

Therefore, when the position of the predetermined icon matches the position of the own vehicle from the script icon table, or when the own vehicle moves to the vicinity of the predetermined icon, for example, on the screen of the display unit 3, When a predetermined icon and a mark indicating the position of the vehicle overlap, or when a cursor is placed on the predetermined icon, the icon is regarded as being selected, and a script associated with the icon is executed. You can do so.

When the relationship between the current time and the date, month, day, hour, minute, and second corresponding to a predetermined icon in the script icon table meets a predetermined condition, for example, the current time is changed to a predetermined icon in the script icon table. If the date is later than the corresponding date, month, day, hour, minute, and second, the icon may be regarded as being selected, and a script associated with the icon may be executed.

For editing the script icon table, for example, a script icon table (consisting of ASCII codes) stored in the storage memory 13 can be read via a communication port (I / F unit 14 in FIG. 1) using a personal computer or the like. And can be performed on a personal computer using predetermined editor software. Further, when the processing is performed on the navigation device side, application software for that purpose may be prepared in the navigation device side in advance.

FIG. 12 shows an example of a script for executing a script associated with a script icon. In this example, the position of the own vehicle is calculated based on the latitude / longitude of the script icon A1 and the script icon A3.
The script of the script icon A1 is executed up to the latitude / longitude of the script. If the latitude / longitude of the own vehicle is equal to the latitude / longitude of the script icon A2, the script of the script icon A2 is executed. When the latitude / longitude of the car is equal to the latitude / longitude of the script icon A3, the script of the script icon A3 is executed "is repeatedly executed.

In the script shown in FIG. 12, instead of "if latitude / longitude = latitude / longitude then of script icon A2", for example, "if current year / month / day / hour / minute / second> script icon A2 / month / month" Date, minute, second, then ". in this case,
When the current date, month, day, hour, minute, and second are later than the date, month, day, hour, minute, and second of the script icon A2,
Will be executed.

FIG. 13 shows an example of the script of the script icon A1. This script is for executing an operation of attaching a predetermined mark to the position of the own vehicle. FIG. 14 illustrates an example of the script of the script icon A2. This script is for switching the map level, that is, the scale.

FIG. 15 shows an example of the script of the script icon A3. This script will say "Exit"
Is displayed on the screen of the display unit 3,
A voice message saying "finished" was sent to the speaker unit 7.
This is for more output.

FIG. 16 shows an example of a script for taking in mark information in a range designated by the user on the external device side. This script uses the script icon A3 from the latitude / longitude of the script icon A1.
Mark information table stored in the storage memory 13 during the movement to the latitude and longitude (described later with reference to FIG. 23).
Is transmitted to an external device via a communication port (I / F unit 14).

Next, referring to the flow chart of FIG. 17, a mark is pasted on the position of the own vehicle on the map displayed on the screen according to the script shown in FIG. The operation for enlarging a message or outputting a message will be described. Before the process shown in the flowchart of FIG. 17 is executed, the user first configures the operation unit 10 as shown in FIG. The script icons A1 to A3 are pasted on the map by operating a keyboard, a joystick, a touch panel, or the like. The map is displayed on the display unit 3 by the CPU 11 based on the map data stored in the electronic map data storage unit 9 in advance.

Next, the script shown in FIG. 12 is fetched from an external device via the I / F unit 14. As a result, the script shown in FIG. 12 is in an execution state, and the preparation is completed. At this point, the vehicle has not yet reached the position of the script icon A1.

First, in step S41, the position data acquisition section 8 acquires the position (latitude / longitude) of the own vehicle. Next, in step S42, the position of the own vehicle is changed from the script icon A1 to the script icon A.
It is determined whether or not it is within the range up to 3 (path range (range indicated by character a in FIG. 19)). The position of the vehicle changes from the script icon A1 to the script icon A.
If it is determined that the number is within 3, the process proceeds to step S43, and the script corresponding to the script icon A1 is executed.

That is, while the vehicle moves from the script icon A1 to the script icon A3 according to the script shown in FIG. 12, the script corresponding to the script icon A1 shown in FIG.
As shown in the figure, every time 15 minutes elapse, a predetermined mark (in this case, a square mark (icon)
“□”) is pasted. Therefore, the square mark “□” indicates the traveling history of the own vehicle. Here, the mark “●” in the figure indicates the position of the own vehicle.

Then, the process proceeds to a step S44, wherein it is determined whether or not the latitude / longitude of the own vehicle is equal to the latitude / longitude of the script icon A2. When it is determined that the latitude / longitude of the vehicle is equal to the latitude / longitude of the script icon A2, the process proceeds to step S45, and the script corresponding to the script icon A2 is executed.

That is, as shown in FIG. 20, when the vehicle (represented by the mark “●”) reaches the position of the script icon A2, the script corresponding to the script icon A2 (the script shown in FIG. 14) ) Is executed,
The map scale changes automatically. In this case, the map is enlarged. FIG. 20 shows that the scale of the map has already been changed,
The map is shown in an enlarged state.

Thereafter, the flow advances to step S46. On the other hand, if it is determined in step S44 that the latitude / longitude of the vehicle is not equal to the latitude / longitude of the script icon A2, the process proceeds to step S46.

In step S46, the latitude of the vehicle
It is determined whether the longitude is equal to the latitude / longitude of the script icon A3. If it is determined that the latitude / longitude of the vehicle is not equal to the latitude / longitude of the script icon A3,
Returning to step S41, the processes after step S41 are repeatedly executed. On the other hand, when it is determined that the latitude / longitude of the vehicle is equal to the latitude / longitude of the script icon A3, the process proceeds to step S47, and the script corresponding to the script icon A3 is executed.

That is, as shown in FIG. 21, when the vehicle reaches the position of the script icon A3, the script corresponding to the script icon A3 (the script shown in FIG. 15) is executed. That is, the display message "end"
Is displayed on the screen of the display unit 3, and the voice message “finished” is output from the speaker unit 7.

After that, the process ends.

Next, with reference to the flow chart of FIG. 22, an operation of transmitting mark information within a specified predetermined range to an external device in accordance with the script shown in FIG. 16 will be described. Before the processing shown in the flowchart is executed, first, from an external device,
The script shown in FIG. 16 is the communication port (I / F unit) 1
4 As a result, the script shown in FIG.

First, in step S51, the latitude and longitude of the mark information are obtained from the mark information table.
Next, in step S52, it is determined whether or not the latitude / longitude of the mark information is between the latitude / longitude of the script icon A1 and the latitude / longitude of the script icon A3. If it is determined that the latitude / longitude of the mark information is between the latitude / longitude of the script icon A1 and the latitude / longitude of the script icon A3, the process proceeds to step S53, where the mark information table shown in FIG. The mark information is transmitted to an external device via the I / F 14.

That is, the mark information of the mark information table, which exists between the latitude / longitude of the script icon A1 and the latitude / longitude of the script icon A3 and is formed by the ASCII code as shown in FIG.
/ F unit) and transmitted to an external device via.

The mark information table is displayed every 15 minutes according to the script corresponding to the script icon A1.
When the mark “□” is pasted at the position of the vehicle on the screen, the latitude / longitude at which the mark was pasted, the date, month, day, hour, minute, second, and the icon number used (in this case, the mark (icon) 23), and character information such as a place name near the latitude / longitude to which the mark is attached is supplied to the storage memory 13 and the like.
Is stored in a format as shown in FIG. The format of the mark information table shown in FIG. 23 is almost the same as the format of the table in the current navigation system.

When the process of step S53 is completed, the process returns to step S51, and the processes after step S51 are repeatedly executed. On the other hand, when it is determined in step S52 that the latitude / longitude of the mark information is not between the script icon A1 and the script icon A3,
Alternatively, if it is determined that the above processing has been completed up to the end of the mark information table, the processing is ended. Also, without making these determinations, the mark information tables can be collectively transmitted to an external device.

For example, the mark information table supplied to an external device such as a personal computer includes information such as a position (latitude / longitude), year / month / day / hour / minute / second, and a nearby place name. It can be displayed on the screen as the driving history of the car and edited.

Further, a map (similar to the map shown in FIGS. 18 to 21) corresponding to the map data stored in the electronic map data storage section 9 is displayed on the screen of the personal computer, and the mark information table is displayed. For example, a mark (icon) “□” can be pasted at a position corresponding to the position information. The position where the mark “□” is affixed indicates the past running history of the vehicle.

As described above, a series of operations and procedures are described by a script, a program (interpreter) for interpreting and executing the script is prepared in the apparatus (navigation system), and a communication port (I / By supplying the script via the (F unit) 14, a complex process (a series of operations and procedures including conditions) can be executed without the intervention of the user, so that the operation can be simplified. In addition, a script is transmitted to the device side, and the device is controlled according to the transmitted script to obtain predetermined information and data, or conversely, an external device performs predetermined processing according to the script transmitted from the device. , Predetermined information or data can be transmitted to the device side.

If the script icon is pasted on the map in advance, for example, when the vehicle moves to the position (latitude / longitude) where the script icon is pasted, the icon is selected. It is possible to automatically execute the process described in the script corresponding to the script icon.

Further, the script can be transferred from any device provided with the communication port 14, so that the cost can be easily reduced.

In the above embodiment, the case where the present invention is applied to a navigation system has been described. However, the present invention can be applied to an AV (Audio Visual) device and other devices.

In the above embodiment, the mark is pasted. However, a script icon may be pasted.

In the above embodiment, when the script icon and the mark indicating the position of the vehicle overlap, the script icon is executed. However, by overlaying a predetermined cursor on the script icon, the script icon is displayed. It can also be executed.
