Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for mainly supporting maintenance staff and maintenance / management work, and more particularly to a portable terminal and a support system using the portable terminal.

[0002]

2. Description of the Related Art For example, maintenance work and maintenance work for patrol and maintenance of water pipes, gas pipes, electricity, and various other facilities (plants, facilities in buildings, etc.) can be performed more smoothly. Conventionally, various systems / methods for assisting correct execution have been proposed, and in particular, in recent years, a support system using a portable terminal (portable information processing device such as a portable terminal or a notebook personal computer) has been proposed. It has become so.

For example, in the invention of Japanese Patent Application Laid-Open No. Hei 7-262225, in plant monitoring, a maintenance staff or the like directs a portable terminal to an intended one of a plurality of facilities constituting a plant, thereby enabling a terminal position direction to be monitored. The position of the portable terminal and the pointing direction of the terminal are measured by the measuring means, and based on the measurement result and the position information of each equipment, the equipment to be operated or operated by maintenance personnel can be specified, and a quick and accurate plant Maintenance work becomes possible.

According to the invention disclosed in Japanese Patent Application Laid-Open No. 9-107410, a maintenance person who patrols a building carries a computer, a GPS receiver, and a wireless communication device, inputs current position information from the GPS receiver, and inputs the position information to the computer and the GPS receiver. The data is transmitted to the computer of the business office by the wireless communication device. The office computer displays the current location of each maintenance person on a map displayed based on the map data. In this way, the current position of the patrol personnel who is patroling can be reliably grasped at the sales office.

[0005]

By the way, a maintenance person who performs maintenance / inspection of water pipes, gas pipes, electric power transmission lines, and other various facilities around the city or the like is, for example, a paper map on which plumbing information is written. I go to the site with inspection etc. and carry out inspection and maintenance work, but write down information such as what I noticed on a paper map or on my notebook (in that case, the location, date and time etc. This information will be referred to during the repair work.

However, the maintenance staff sometimes forgets to write the location, date and time, and the like, and if the way of writing the location is ambiguous, a third party may not be able to specify the exact location even when viewed from behind. Alternatively, for example, if the location information is described as "~ school front gate", etc., if the surrounding environment has changed completely due to an earthquake, etc., or if the main gate is lost or moved due to relocation, renovation etc. In addition, it is difficult to accurately determine the position, which hinders inspection and repair work.

It is also conceivable that a maintenance person brings a personal computer or the like to the site and inputs data. However, in many cases, the maintenance person is not accustomed to hitting a keyboard or the like to input data. Furthermore, in many cases, there is no situation in which a computer can be used and a keyboard can be input. In recent years, various portable terminals have been put on the market, and many of them have a memo function for easily writing characters / graphics on a tablet with a pen or the like as desired. By using the memo function of such a portable terminal, even a person who is not accustomed to operating a keyboard or the like can easily input data, but if you forget to write the place in the contents of the memo, after all,
It is the same as the case of writing on the paper (although date and time data can be automatically added by a clock function).

Further, even if the location, date, etc. are not forgotten, the information is useful only for the individual as it is. Unless the memo content is conveyed, it will not be useful information for the entire maintenance and management work, and will not be able to make full use of the precious information.

In recent years, a GIS (Geograph) capable of converting a map into electronic data and displaying / editing it, and displaying a position on the map in association with some data has been developed.
ic Information System (Geographic Information System) technology is developing, so-called "car navigation system"
It is well-known that it is used in various fields, but applied technologies are being proposed in various other fields. Therefore, in the field of maintenance / inspection work for water pipes, gas pipes, power transmission lines, and other various facilities, map information should be created by adding data indicating the status of piping such as water pipes to ordinary map information. Etc. are considered, but G
There is an expectation for the development of a technology that uses the IS technology to support operations such as maintenance and inspection and management thereof so as to be easily performed.

An object of the present invention is to improve the work efficiency of operations such as maintenance and management by associating position information on a map with memo data and allowing a plurality of maintenance staff to share the memo data. And a mobile terminal for the support system.

[0011]

A portable terminal according to the present invention displays a map using memo input means for inputting memos of arbitrary data, and stored map information.
A GI for detecting information of a designated position on the map at least when a memo is input by the memo input means;
S means and a management table for storing the position information detected by the GIS means and the file name of the memo data input by the memo input means in association with each other.

When the portable terminal having the above configuration is used, for example, when a user such as a maintenance person writes a memo at each site, the user specifies the position of the site on a map. Therefore, it is not necessary to forget the information of the place where the memo was written, and it is not necessary to know the name or the like of the place, so that effective information can be easily and surely left.

A maintenance support system using a portable terminal according to the present invention comprises: a server connected to a LAN; communication means for freely connecting / disconnecting to / from the LAN and transmitting / receiving data to / from the server via the LAN when connected; Memo input means for memo inputting the data of the data, and displaying a map using the stored map information, and detecting information of a position designated on the map at least when a memo is input by the memo input means. GIS means for performing the
A mobile terminal having a management table for storing the location information detected by the S means and the file name of the memo data input by the memo input means in association with each other, wherein the mobile terminal is all or designated The memo data and the data in the management table related to the memo data are transmitted to the server, and the server stores the memo data transmitted from each mobile terminal and creates a unified management table for centrally managing the memo data. Alternatively, the portable terminal receives arbitrary memo data from the memo data stored in the server.

According to the maintenance support system configured as described above, a plurality of users (for example, maintenance personnel belonging to a certain sales office)
However, the data written on each portable terminal can be made useful information that is shared by all the members, instead of merely useful information for the individual.

The portable terminal is, for example, a pen-input portable terminal, from which memo data to be associated with the position information can be freely input as if writing characters or pictures on paper.
In many cases, it is difficult to operate a personal computer (it is difficult to hit a keyboard) at a site or the like, but a pen input type makes operation relatively easy.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram of the entire maintenance support system of the present embodiment.

In the following description of the embodiment, the pen input portable terminal 2 will be described as an example of the portable terminal, but the present invention is not limited to this. Any portable information processing terminal may be used. However, it is desirable to have a pointing device (a device that provides a function like a so-called “mouse” provided in a notebook personal computer or the like).

The system shown in FIG. 1 is installed at a place where maintenance personnel base business activities, such as a sales office. In FIG. 1, a server machine 1 is always installed in a business office or the like, and is connected to a LAN 3. The server machine 1 transmits and receives data to and from each pen input portable terminal 2 via the LAN 3, and is shared and used by each maintenance staff. The stored data is stored, and each maintenance worker can download desired data to the pen input portable terminal 2 as needed and use it.

The pen input portable terminal 2 is basically a general portable terminal which is a small-sized information processing device which can be carried to a place where the user is away from home. In particular, a touch panel is provided on a display, and a touch pen or the like is used. Anyone can easily input information and perform various operations using the dedicated input pen 2a. In addition, the pen input portable terminal 2 has L
An interface for connecting to the AN 3 and a communication function for transmitting and receiving data via the LAN 3 are provided.
3 to access the server machine 1 or LAN
3 and can be carried on site.

Usually, the portable terminal has a word processing function,
Although it has a scheduling function, a memo function, and a communication function (such as e-mail), the pen input portable terminal 2 of the present embodiment further includes a GIS (Geographic Infor
mation System (Geographic Information System) It has a map information display / edit function using technology. Then, as described later in detail, a position designated by the user (the person who uses the pen input portable terminal 2 such as the above-mentioned maintenance staff is collectively referred to as a user in the future) is designated on the displayed map. And a management table that associates memo information created by the memo function (information related to the work performed) with the memo information.

A GPS receiver 4 may be connected to the pen input portable terminal 2 if necessary, and the current position information (latitude / longitude information) measured by the GPS receiver 4 may be used. (Alternatively, a pen input portable terminal with a built-in GPS receiver may be used).

The memo information created by the pen input portable terminal 2 carried by each maintenance staff at the site or the like by each maintenance staff and the association data between the location information and the memo information (data of a management table described later) are later stored in the sales office. In such a case, the pen input portable terminal 2 is connected to the LAN 3 and uploaded to the server 1. In this way, by allowing the server 1 to centrally manage the memo information created by each maintenance staff, the contents written by each maintenance staff can be shared information that can be used not only by oneself but also by others. It can be. That is, if necessary, memo information and the like written by another person can be downloaded from the server 1 to the pen input portable terminal 2 via the LAN 3 and can be referred to as necessary.

The above-mentioned maintenance support system will be described in detail below. First, the pen input portable terminal 2 will be described. FIG. 2 is a conceptual diagram illustrating a memo function part of the pen input portable terminal 2.

FIG. 1 schematically shows the functions of an application program portion particularly relating to the features of the present embodiment in the pen input portable terminal 2, and also performs external data input / instruction to the application 10. Input / output device 17 (the above display (with touch panel)
And a pair of input pens 2a).

The memo function unit 11 basically provides a memo writing function mounted on an existing portable terminal, personal computer, or the like, and allows the user to write a character or picture on paper with a pen. Information can be written as desired, and the written data is stored as a memo data file 11a and can be referred to / updated later. However, the memo function unit 11 of this example further includes a GIS function unit 13 It operates in cooperation with the application.

The map data storage unit 12 stores map data created in advance. This map data is obtained by adding general map information such as a house map / road map to information related to the users, for example, various pipes and facilities to be managed.

The GIS function unit 13 includes the map data storage unit 1
2 provides a function of operating, displaying, editing, and the like using the map data stored in the storage unit 2, and may be realized by using the function of existing software.
There are various functions of the existing GIS software, but basically, for example, enlargement / reduction of a specific area designated by a user, and call-up and display of information related to a position designated by a user. Various types of information related to map information, such as displaying a specific place on the map (for example, a place that satisfies the input conditions) in color and displaying a figure / character / symbol etc. created by the user on the map. It provides a function to create / display / process information. In this example, as will be described later in detail, a position designated at the time of memo creation is detected, and the detected position information 14 is
The memo data file 11a is stored in the management table 16 in association with the file name 15 of the created memo data file 11a.

FIG. 3 is a diagram showing a procedure for inputting memo information in the pen input portable terminal 2. The pen input portable terminal 2 of the present embodiment includes the memo function unit 11 as one of various functions.
It operates in cooperation with the S function unit 13. In other words, when calling the memo function, a specific position on the displayed map must be specified, so that maintenance personnel etc. must also leave information on the location when writing the memo. You do not need to worry about having to do so, and the location data is surely stored along with the written memo information. Regarding the memo function, normally, as shown in FIG. 3 (a), menus that can be selected on the screen include “new memo” 21, “memo reference / update” 22, and the like. When the selection / designation is performed, a “memo input screen” is displayed. In this example, even if the selection / designation operation is performed, the memo input screen is not immediately displayed. For example, when the user performs an operation of designating “new memo” 21 using the input pen 2a, an arbitrary position (a place corresponding to the contents of a memo to be written) is designated on the displayed map (input It shifts to the mode (pointing with a pen). still,
This may be a mode in which the mode is shifted to the above-mentioned mode by designating “new memo” 21 while the map is always displayed, or when the “new memo” 21 is designated, the GIS function unit 13 May be activated to display a map in the above mode.

When the user taps an arbitrary position on the map displayed on the display, for example, as shown in FIG. 3A using the input pen 2a, the GI
The S function unit 13 detects position information of the pointed point (this may be actual latitude / longitude information or coordinate data on a predetermined map), This position information 14 is stored. Thus GIS
When the detection / storage of the position information is completed by the functional unit 13,
The memo function unit 11 displays a “memo input screen” as shown in FIG.

The user can freely memoly write the information to be written on the "memo input screen" using the input pen 2a as if writing characters or pictures on paper with a pen or the like.
For example, as shown in the example of FIG. 3B, information to be written on the “memo input screen” (in this example, “there is corrosion.
Yamada ”).

When the memo writing is completed, the "memo input screen"
When the "register" button 23 is tapped, the memo data file 11a is created / stored, and at least the memo data file name 15 and the position information 14 are stored in the management table 16 in association with each other. In this example,
For example, as shown in FIG. 4, a primary key for linking (associating) the memo data file name 15 with the position information 14 is automatically issued (for example, a terminal number previously assigned to the pen input portable terminal 2 and Using the current date / time / time data obtained by the clock function, a key value in the form of "terminal number-year / month / day / hour / minute / second" is created), and the memo data file name and the location information are associated with this primary key. Attached (further, various types of information may be associated), and the management table 16
To be stored.

FIG. 5 shows an example of the management table 16. The management table 30 (16) shown in FIG.
1, “location information (X)” 32, “location information (Y)” 3
3, "memo data file name" 34, "memo creation time"
35 fields. In addition to the above, usually, memo data is provided with, for example, update date and time, creation / updater name, and important rank as attribute information thereof.
Alternatively, depending on the situation, for example, various information as shown in a search condition specification window described later is added, and therefore, a field for storing such information may be present.

In the field of "primary key" 31, a key value in the format of "terminal number-year / month / day / hour / minute / second" automatically issued is stored. FIG. 3 shows an example of a key value issued assuming that the terminal number of the pen input portable terminal 2 is S001.

The above-mentioned position information is stored in the fields of “position information (X)” 32 and “position information (Y)” 33. As described above, X and Y may mean latitude and longitude, or may mean (X, Y) coordinates in a map.

The field of "memo data file name" 34 stores the file name 15 of the created memo data. FIG. 9 shows an example in which the memo data file name 15 is also automatically created in the format of "terminal number-year / month / day / hour / minute / second.bpm". Note that the memo data file name 15
May be arbitrarily named by the user.

In the field of “memo creation time” 35,
The date and time data when the memo data file 11a was created (in the example of FIG. 3, date, month, day, hour, minute, second) is stored. In general, not only mobile terminals but also information processing devices are necessarily provided with a clock function.
It is not necessary to worry that not only the place information but also the creation date and time must be written with the memo to be created one by one, and the trouble can be saved.

When displaying the map, the GIS function unit 13 stores the position information (“position information (X)” 32, “position information (Y)” 33) stored in the management table 30.
(Or a separate storage area for storing the position information 14 is provided, and the position information 14 is read therefrom), and a mark (memo mark) indicating that memo data is present at the location of the position information 14 on the map. ) Is displayed. For example, as shown in FIG. 3C, a memo mark “M” is displayed on the map screen.

Thus, the user can see at a glance which place the memo has been recorded on the map screen. Furthermore, it is convenient when the contents of the created memo are later referred to or updated. For example, "Memo reference / update"
Is specified, and the position where the memo mark "M" is displayed on the displayed map is tapped with the input pen 2a, and the management table 30 is searched using the pointed position information as a key, and the search hit data is displayed. Is read, and the contents of the memo data file having this file name are displayed. As described above, by visually specifying the place where the user wants to view the memo, the contents of the memo can be referenced or updated.

It should be noted that information in any of the fields 31 to 35 described above is also uploaded /
This can be one of search conditions at the time of download. Here, in the above-described example, when writing a memo, the user specifies an arbitrary position on the map using the input pen 2a. However, as described with reference to FIG. Connect receiver 4 (or GPS
The current position information (latitude / longitude information) measured by the GPS receiver 4 may be used (using a pen input portable terminal with a built-in receiver). In this case, for example, the user only has to start the memo function and write the memo, and the management table 30 is automatically created using the current position information measured by the GPS receiver 4. Also,
The method using the GPS receiver 4 has an advantage that the current position can be surely grasped even when the surrounding environment is significantly changed due to an earthquake or other natural disaster or a human disaster. On the other hand, in practice, there are cases where the operator inputs memo data collectively after performing, for example, two or three places of work. In such a case, the method using the GPS receiver 4 requires the memo data. Since the current position when performing the input operation of the memo data is different from the position of the target site of the memo data (for example, by moving from a business office by car and parking somewhere, (For example, when the user returns to the car and enters memo data in the car after walking around a plurality of sites), it is better to use a method in which the user specifies an arbitrary position on the map.

Thus, in the configuration in which the GPS receiver 4 is connected to the pen-input portable terminal 2 (or the pen-input portable terminal with a built-in GPS receiver is used), the current value automatically measured by the GPS receiver 4 A configuration in which a mode in which the position information is used and a mode in which the user can arbitrarily specify the position may be switched. It should be noted that an existing navigation function may be further provided so that when a destination is specified, a guide from the current position to the destination is provided.

The management table 30 and the memo data file 11a are not necessarily all created by the pen input portable terminal 2. Created by another maintenance person (with another pen input portable terminal 2), and as described later, the server machine 1
In some cases (or all) data downloaded from the server machine 1 and stored.

That is, the management table 30 and the memo data file 1 newly created by the pen input portable terminal 2
1a, when this user returns to the place where the server machine 1 is installed, such as a sales office, for example, LA shown in FIG.
In the N system environment, uploading (memo data transmission) to the server machine 1 via the LAN as shown in the schematic diagram of FIG. 6 so that other people can use it. In addition, when going out of the business office to the site, the data stored in the server (the data uploaded by the user and others to the server) can be used to input the necessary data at that time. 2 (receive memo data) and use it.

This will be described in detail below. FIG. 7 is a diagram for explaining an example of a method of sharing memo data. In the drawing, a storage unit (hard disk, RAM, flash memory, etc.) in each pen input portable terminal 2 has a storage area for storing the management table 30 and the memo data file 11a. When uploading to the server machine 1, data stored in the management table 30 of the pen input portable terminal 2,
And the memo data file 11a is transferred to the server machine 1, but may be a form in which all data is simply transmitted. However, as described below with reference to FIG. May be transmitted.

FIG. 8 is a diagram showing an example of a transmission data selection method when transmitting memo data to a server machine. First, as shown in FIG. 8A, when the user designates “send memo” 41 from the displayed menu, two options of “select from map” 42 or “select condition” 43 are displayed. Is done.

When "select from map" 42 is specified,
The mode shifts to a mode in which the user can specify an arbitrary area on the displayed map. For example, as shown in FIG. 8B, the user writes an arbitrary area on the displayed map using the input pen 2a (writes a frame 45). For example, a line may be drawn, or the frame 45 may be automatically set when two rectangular vertices are specified. Further, the shape of the frame 45 is not limited to the rectangular shape shown in the figure, but may be any shape. By performing such an operation, the memo data file 11a included in the designated area, that is, the memo data file 11a in which the memo mark "M" is displayed in this area, for example, is selected. This corresponds to, for example, “position information (X)” 3 in the management table 30.
2. Search the field of “position information (Y)” 33 to determine whether or not this position information is within the area range;
By reading the “memo data file name” 34 of the record determined to be within the area range, the memo data file 11 a to be transmitted to the server machine 1 is determined. In this way, even a user who is not accustomed to operating a computer can easily select necessary data in a visually understandable state. Alternatively, for example, when it is desired to transmit only data corresponding to the work performed on that day, and when the work place is concentrated in a specific area, the necessary memo data can be selected / designated particularly easily. Become.

On the other hand, when "condition selection" 43 is designated, a search condition designation window 40 as shown in FIG. 8C is displayed. Of course, this is only an example, and the search condition is determined and created as appropriate according to the contents of the business or the situation of the business office.

In the example shown in FIG. 8 (c), for example, the memo data file name (memo title) is directly input, the creation date (or update date) of the memo data and its period, other, the construction category, the name of the contractor, etc. The search condition of is shown,
When the user appropriately inputs at least one or more conditions from the search conditions and clicks the “execute search” button 46, the management table 16 is searched based on the input conditions, and records matching the input conditions are obtained. Is extracted, and the memo data file 11a having this file name is transmitted to the server machine 1. Although the construction section, the name of the contractor, and the like are not particularly described, in this example, the user inputs the memo data file 11a when the memo data file 11a is created, and the management table 30
(Alternatively, the data such as the construction category and the name of the contractor are stored in advance in association with each position on the map, and the data relating to the position of the position information 14 is automatically extracted. May be stored in the management table 30).

Returning to FIG. As described above, when the management table 30 and the memo data file 11a are uploaded from each pen input portable terminal 2 to the server machine 1, these are stored in the database 60 of the server machine 1 and are centrally managed. That is, the server machine 1
Database 60 stores a memo data file 61 (this means, in particular, a memo data file 11a sent from a plurality of pen input portable terminals 2). Centralized management table 50 for managing data file 61 (group of data of management table 30 sent from pen input portable terminal 2)
Is stored in the storage area.

The management table 50 has basically the same field configuration as the management table 30. That is, the unified management table 50 basically includes a “primary key” 51,
"Position information (X)" 52, "position information (Y)" 53,
"Memo data file name" 54, "Memo creation time" 55
And so on.

The user, for example, before going out to work,
Necessary data is downloaded from the server machine 1 to the pen input portable terminal 2 of the user. The method of selecting / designating necessary data is substantially the same as the method at the time of upload described in FIG. That is, the pen input portable terminal 2 is connected to the LAN.
9A, when "select memo" 44 is selected / designated and input from the menu as shown in FIG. 9A, for example, although not specifically shown, "select from map" or "select condition" is selected. Two options are displayed.

When “select from map” is specified, FIG.
As in the case of (b), the user can specify an arbitrary range on the map displayed as shown in FIG. 9B, for example. At this time, the “location information (X)” 52 and “location information (Y)” 53 of all the records stored in the management table 50 of the server machine 1 are read, and the above-mentioned The mark “M” may be displayed.

On the other hand, when "condition selection" is designated,
For example, a search condition designation window 70 as shown in FIG. 9C is displayed. This may be the same as the search condition specification window 40 shown in FIG. 8 (c), and the description thereof is omitted.
By searching the management table 50 of the server machine 1, the memo data file name of the record that matches the search condition is extracted, and the memo data file with this file name is downloaded from the server machine 1.

As described above, each user can share and use the information obtained by other users, and can effectively use the information which is originally the information of each user in the entire work such as maintenance and management. Will be able to

The server machine 1 and the pen input portable terminal 2
The internal hardware configuration is not particularly shown. The configuration may include a general CPU, a memory / storage unit, an input / output unit, a communication unit, and the like.

[0055]

As described above in detail, according to the portable terminal of the present invention and the support system using this portable terminal, the memo creation function and the map display / editing function (GIS) are linked, and Since the memo data and the location information are stored in association with each other, and the location where the memo data exists is displayed on a map, necessary information can be reliably left without the user being particularly conscious. The target memo data can be searched for on the map when the reference / edit is performed later. Furthermore, by centrally managing the data input by each mobile terminal by a server or the like, the memo data written by each user can be shared. In this way, it is possible to improve the work efficiency for each user or as a whole work such as maintenance and management.
