Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple conference system for displaying electronic information using a liquid crystal display tablet and using it for a work meeting at a construction site.

[0002]

2. Description of the Related Art For example, it is said that the number of working workers a day at a work place for construction work is about 1/5 of all the workers to be managed at the work place. That is,
It means that workers of various industries and contractors are working every day, but workers are frequently changed on a daily basis according to the work process.

Further, generally, in a work place of a certain scale, the number of companies (traders) or occupations involved is increased to tens to hundreds even on a daily basis, and the progress of work, the confirmation and adjustment of the progress according to the construction period are adjusted. For that, the meeting is indispensable.

Therefore, at a work site such as a construction work in which a variety of industries and contractors mix with each other in this way, it is necessary to issue a work schedule and a safety instruction sheet, especially at the start of work or at a fixed time. Will become very important.

FIG. 10 is a diagram showing an example of a work schedule / safety instruction document.

The work schedule / safety instruction sheet is, for example, as shown in FIG. 10, a company such as an affiliated company or a subcontractor, job type, schedule, performance, work content, safety instruction, foreman, construction type, work place, floor, and part. The number of lines is close to several tens to one hundred even if they are combined on a daily basis. Therefore,
Even if these are written on a large sheet of paper, many sheets of paper are needed and it is difficult to organize them all. In such meetings, not only work schedules / safety instructions but also confirmation tables for loading / unloading vehicles and usage schedules for lifting machines,
Dangerous work instruction drawings, work content layout drawings, process control charts, etc. are also required at the same time to confirm the work. for that reason,
A large space for presenting these tables and drawings is also required.

[0007]

[Problems to be Solved by the Invention] As mentioned above, at the workplaces where the related companies and occupations are exchanged every day, and there are a large number of them, check these companies, occupations, and other items one by one, and follow the work schedule and safety instructions. In order to hold a meeting, since the number of items increases, the size of the work schedule / safety instruction sheet becomes large, and there is a problem that the efficiency in preparing and proceeding with the meeting is low.

[0008] For example, early work / overtime work is routinely carried out by some work, and grasping this notification and checking lighting etc. are one of the main management tasks, but many companies, places, etc. are dispersed. Therefore, the burden for those inputs is large.

[0009] In addition, in recent work places that employ the scaffold-free construction method, table lift type or crawler boom lift type aerial work vehicles have been introduced for work in high places such as ceilings. Especially in large-scale construction, hundreds of equipment such as cranes and work platforms for aerial work can be reached. Then, these are introduced to the work place by a lease contract and rented out as needed. In addition, there are cases in which several units are deposited for each foreman, but in this case as well, there are extra contractors and shortage contractors, and as a whole, the number of leases is large.

[0010] However, in reality, there is a problem that the borrowing / returning status is not clear because it is in an unmanaged state, and there are many things left abandoned at the site. Especially in the battery type, if the battery is discharged, it becomes unusable and is left as it is. Also, in high-rise buildings, it takes time to find empty equipment even if it is available. As a result, a lot of play equipment is required, and for large-scale construction that takes, for example, 20 months from the start of construction to completion,
A problem arises in that huge lease costs will be incurred for vacant equipment during that period.

The present invention is intended to solve the above-mentioned problems, and it is possible to handle a large amount of information in a normal meeting space without having a large space, so that even a small number of people can efficiently use it, and at the same time at different places. It is an object of the present invention to provide a simple conference system that enables work meetings and the like.

The above construction is provided, for example, in a work room on each floor and other work sites. The parent data processing device 7 is
A parent C that is connected to multiple terminals and installed in a central control room
A PU, which is a conversion program 14 and an editing program 15
Etc., the data file 8 is organized by performing code conversion and editing of image data input at the terminal, and data is sent to the terminal as necessary. The conversion program 14 is for, for example, performing pattern matching to recognize image data of handwritten characters and converting it into character code data, or converting image data such as a table drawn by handwriting into line drawing code data. Reference numeral 15 is for sorting and searching items to organize data. The data file 8 includes various list data, work instructions and machine lending documents created on each terminal,
It stores management data such as a crane order table.

In the master side data processing device 7, as shown in FIG. 2, for example, the terminals are periodically called in sequence (step S

3) Perform editing processing such as sorting (step S
4) and stores it in the data file 8 (step S5).
At the same time, the converted code data is returned to the terminal (step S6).

In contrast to the above-mentioned processing by the parent data processing device 7, the child data processing device 2 on the terminal side stores the data input from the liquid crystal display tablet in the memory 3 and calls it from the parent side. Wait for (step S
11), send the input data to the parent side (step S1)
2). After that, the parent side converts the image data into code data and captures the returned data (step S1).
3) Replace the image data in the memory with the code data (step S14).

FIG. 3 is a diagram showing an example of an initial menu screen, FIG. 4 is a diagram showing an example of a management table of data such as work instructions, and FIG. 5 is for explaining a process of creating and updating forms etc. on the child side. FIG.

In the data processing device 2 on the terminal side, by displaying an initial menu screen as shown in FIG. 3, each form or the like is created and updated while managing the storage state of the memory 3 with a management table, for example. The management table has, for example, as shown in FIG. 4, “presence / absence” and “processing” flags and a data pointer DP for each form or the like. The "presence / absence" flag is set to "1" when the data is already present in the memory 3 on the terminal side, and is set to "0" when it is not present. The "processing" flag is "1" when the data is stored in the memory 3 in the state of being created and updated in the terminal.
When the image data is replaced with the code data by performing the processing described with reference to FIG. 2, it is set to “0”. The data pointer DP points to the storage position of the data.

Therefore, according to the example of the management table shown in FIG. 4, some work instructions are already stored in the memory 3 on the terminal side, and the data is still stored in the state of being processed and updated. It is stored in the location "01". However, the machine lending book shows that although the data already stored in the memory 3 on the terminal side has been processed by the process shown in FIG. 2, the data is stored in the location "02". Indicates that there is no data in the memory 3 on the terminal side. That is, the data whose “processing” flag in the management table is “1” indicates that the data has not been transmitted to the parent side. Therefore, in the data processing device 2, when the parent side calls, Send data with the "processing" flag in the management table set to "1",
The process of FIG. 2 is performed and the "process" flag is rewritten to "0".

When creating or updating each form or the like, when any of the fields of the form or the like of the option in the initial menu shown in FIG. 3 is touch-input, the process shown in FIG. 5 is executed. First,
By referring to the management table of FIG. 4 (step S21), it is checked whether the "presence or absence" flag is "1" or "0" (step S2).
2). If the "presence / absence" flag is "0", the parent side is requested to transmit data (step S23). Then, when the data is transmitted from the parent side, and when the “presence / absence” flag is “1”, the data is read from the location of the data pointer DP in the memory 3, displayed on the liquid crystal display tablet 1, and the update mode is executed. (Steps S24 to S25). That is, in this case, the standard format data stored in the parent data file 8 is used, or the data created by another terminal is used. When the information without data is received from the parent side, the mode is switched to the creation mode (steps S24 to S26). It is checked from the name column of the management table whether or not it is a new form (step S27). If it is a new form, the name is registered in the name column and the created data is stored in the memory 3. The location is registered in the data pointer DP, and "1" is written in the "presence or absence" flag and the "processing" flag (step S28). For a form whose name has already been registered, the created and updated data is stored in the memory 3, the location is registered in the data pointer DP, and "1" is written in the "presence" flag and the "processing" flag ( Step S29). Note that "1" set in the "processing" flag is the processing of FIG. 2 (step S1).
When 4) is executed, it is rewritten to "0".

The applicant of the present invention has already disclosed, for example, in Japanese Patent Laid-Open No. 1-320.
No. 521, the electronic blackboard conference system, and, for example, the work place management system described in Japanese Patent Laid-Open No. 62-82455 are proposed. These are used as the simple conference system of the present invention. It can be used in combination. The electronic blackboard conference system is a system in which an electronic blackboard is used as a screen to project and display an image on an electronic OHP.
If it is arranged in a large room, the terminal of the present invention may be arranged in a small room.

FIG. 6 is a diagram showing an example of a screen displayed on the liquid crystal display tablet, and FIG. 7 is a diagram showing a data structure.

As described above, the work schedule / safety instruction sheet has a large number of items and lines and cannot be displayed on the screen. Therefore, in the example shown in FIG. 6, the items are divided into a predetermined number of lines. Is displayed. Therefore, the work schedule / safety instruction document for one day is composed of several pages and several days are managed. Therefore,
On the screen of the work schedule / safety instructions projected on the electronic blackboard,
Keys such as screen switching selection and processing mode selection are provided.

In FIG. 6A, for example, reference numeral 41 denotes a page selection switching key, which switches the screen to the selected number of pages when a numeral is selected. Reference numeral 42 is a screen selection switching key, which is A (confirmation table of loading / unloading vehicle), B
(Dangerous work instruction drawing), C (Work content layout drawing), ...
... is switched to a corresponding predetermined screen depending on the selection. Reference numeral 43 denotes a shift operation key, which shifts a screen in which items are not filled and the side (right) side overflows. Reference numeral 44 denotes a day designation key. When the numerical portion of the year, month and day is selected, a ten key is displayed in a pop-up, and the screen for the work schedule / safety instruction sheet corresponding to the day, month and day is switched by the designation on the ten key. Reference numeral 45 denotes a processing mode selection key, for example, an input key is used to enter (execute, confirm) data, an item cancel key is used to selectively cancel items, and a write key is used to write data to each item. Set to mode.

Next, an outline of the entire operation will be described assuming that a work schedule / safety instruction sheet in which no information is input in a preset format is developed by the data processing device and displayed on the screen.

First, the writing mode is set by the processing mode selection key 45. This is performed by managing the display screen by the data processing device and processing the coordinate values in a predetermined area displayed as "write" to be in the write mode. That is, when one point in the predetermined area indicated as written is designated by the special input pen, its coordinate value is recognized on the screen and transferred to the data processing device. The data processor recognizes from the state of the screen that the coordinate value is the selection key for the writing mode, and waits for the next input information in the writing mode.

Then, when the shaded area in the drawing is designated by the input pen and the coordinate values are input, the data processing apparatus recognizes that the company item is selected, and the window (pop-up screen) 46 is displayed as shown in the drawing. Display handwriting input and company list on. The company list is a company that is registered in advance, and items are input by selecting and instructing the company name. Therefore, for example, as shown in FIG. 7, a tree-structured data structure is adopted for each item, and when an item is selected, a list of data is output for each item and data is also provided in the lower layers as needed. is doing. If it is not on this company list, it will be handwritten.

In the case of handwriting input, as shown in FIG. 6B, the input area 4 together with the handwriting input window 47 is further added.
Display 8. Note that FIG. 6B shows an example of the screen on the right side switched by the shift operation key 43 in FIG. 6A. Therefore, when handwriting is input in FIG. Needless to say, the input area 48 is displayed together with the handwriting input window 47. Then, this input area 48
When the company name is written with the input pen and the input processing mode selection key 45 is further selected, the data processing device inputs and processes the coordinate values as the company name in the company item in the image data. By this processing, FIG.
The company name input by handwriting is displayed as it is in the shaded area in (a). Each item is written in this way.

As described above, the work schedule / safety instruction sheet is set, and the items of the processing mode selection key 45 are deleted, inserted,
The move and copy keys perform their respective processes on the data set for writing. Needless to say, the work schedule / safety instruction sheet may be read from the FAX 4 or set.

Next, an example of managing the use schedule of the equipment, the overtime schedule, the registration of the delivery route, etc. will be described. FIG. 8 is a diagram showing an example of the equipment schedule screen, and FIG. 9 is a diagram for explaining a storage example of line drawing data.

In the equipment schedule, the usage schedule of the equipment such as a crane and aerial work vehicle is entered and the operation management of the equipment is carried out. In the case of equipment, for example, large equipment such as a tower crane is used by several companies a day, but small equipment such as a table lifter is used by one company on a daily basis. 8 (a), (b), and (b), which show a small application example in which each equipment is used exclusively by each trader.
(C) shows a large-scale application example in which several companies allocate time and share it.

For example, a small equipment schedule includes columns of company name, equipment name, and scheduled use time, and a large equipment schedule includes columns of company name, scheduled use time, and work content. Then, if you specify the company name field, a list of registered company names will be displayed in a window as shown in (a). If you specify the company name in the list, that company will be displayed as shown in (b). The name is written in the company name field on the equipment schedule.
This is because the company name column in the designated position and the company name in the list are recognized and processed by matching with the position in the equipment schedule displayed on the liquid crystal display tablet. The same applies to equipment names, and calendars and numeric keys are displayed in windows for work days. Also,
In the scheduled use time column, the bars shown in (b) and (c) are drawn by designating the positions of the start and end times of use. The work content is entered in the handwriting mode. Of course, the company name and the equipment name may be entered in the handwriting mode if they are not in the registration list, and the work content may be instructed from the registration list if registered.

In the case of early work and overtime work, the work area is frequently changed, so first of all, an image such as a plan view of each floor is input from the FAX. Then, it is displayed on the liquid crystal display tablet, and for example, in the case of a rectangular area, the four corners are pointed and the partition symbol is input to register the partition. After that, the same as the equipment schedule, the early departure / overtime schedule is displayed, and the company name and section overtime hours are set and entered. By using the sections and times of the early departure / overtime work schedule created in this way as control information for air conditioning and lighting, it is possible to control air conditioning and lighting according to the time schedule for early departure / overtime.

FIG. 9 shows an example of storing line drawing data in the memory. A management table for line drawing data α and β is provided, and each line drawing data is searched from this table.
The pointer is configured to jump to the storage areas I1, I2, .... Each data area has an area for line drawing data and an area for storing size and section information about the line drawing data, and coordinates X ₁₁ , Y ₁₁ → X ₁₂ , Y ₁₂ → ... The partition information is defined by. Therefore, when this line drawing data is displayed on the screen and settings such as early delivery and overtime are set for each area, the point designation etc. can be entered by converting the coordinates of each section from the coordinates of the origin of the line drawing data. If there is, the area is recognized.

Similarly, placement and delivery management is one of the methods for inputting an image and registering and using the section. For example, when arranging and delivering equipment, the location can be registered by instructing where in the work place to use in the work plan, and the delivery route can be sequentially specified from the start point to the end point, and the delivery robot control signal can be specified. It can be used for automatic delivery.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above-described embodiment, the case of using for the meeting at the work place has been described, but the same may be applied to the meeting for other meetings. Further, for example, it may be configured to be used for material management and to obtain inventory from the entry / exit history of materials in each section, or to collect the time of early exit / overtime.

[0039]

As is apparent from the above description, according to the present invention, a parent data processing device is connected to a child data processing device, and information is input by pen input while displaying on a screen with a liquid crystal display tablet. Since it will be done, we will hold meetings at each small and medium-sized site while centrally managing with the parent data processing device,
You can collect that information centrally. Therefore, it is possible to centrally manage dispersed small and medium-sized sites.

Further, since the data processing device is provided with an adapter for converting a signal to and from a FAX and an adapter to convert a signal to and from a video television, a normal F installed at the site is installed.
AX or monitor television can be used as an output device, and the system cost can be reduced.
