Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic conference system which displays electronic information and is used for work meetings 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. 7 is a diagram showing an example of a work schedule / safety instruction document.

The work schedule / safety instructions include, for example, as shown in FIG. 7, companies such as affiliated companies and subcontractors, job types, schedules,
It consists of items such as actual results, work contents, safety instructions, foreman, construction type, work place, floor, site, etc. Even if these are put together on a daily basis, the number of lines is close to tens to hundreds. Therefore, even if these are written on a large sheet of paper, many sheets of paper are required 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 workplace where there are many companies and occupations that are related to each other every day, the companies, occupations, and other items are checked one by one, and a meeting is held with a work schedule and safety instructions. However, there is a problem that the number of items is large and the size of the work schedule / safety instruction sheet is large, which is inefficient when preparing and proceeding with the meeting.

[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 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, and a plurality of people can input and output at the same time efficiently. It is an object of the present invention to provide an electronic conferencing system that enables simultaneous work meetings and the like in different places.

[0012]

To this end, the electronic conferencing system of the present invention comprises an input / output unit comprising input means having a coordinate input function from a panel and output means for displaying and outputting electronic information on the panel, and Data processing means for correlating the information projected on the panel using the output means of the input / output unit with the coordinate input information of the input means, and performing predetermined processing such as creation, retrieval, editing, tabulation of forms, tables and drawings And a plurality of input / output units are connected to the data processing means.

Further, the input / output unit is characterized by comprising an electronic blackboard having a coordinate input function, a projection device for projecting electronic information on the electronic blackboard, and a liquid crystal display tablet.

[0014]

In the electronic conference system of the present invention, a plurality of input / output units are connected to the data processing means, the electronic information is displayed and output from the output means on the panel of the input means, and the coordinates are input from the panel of the input means. Since the information projected on the screen and the coordinate input information are associated with each other and predetermined processing such as creation, retrieval, editing, and tabulation of forms, tables, and drawings is performed, it is possible to hold meetings at a plurality of locations at the same time. Further, even when a large number of people gather and have a meeting in a wide place, the input / output units can be arranged at a plurality of places.

The output processing unit 25 outputs data to a liquid crystal display unit 28, a liquid crystal display tablet, a display, and a printer by referring to a CG (character generator) of characters and images, and an output screen, an operation mode, and other output states, The operation mode and the like are held in the output mode table 26.

An example of the data input process in the work schedule / safety instruction sheet which is displayed on the liquid crystal display unit and is projected on the electronic blackboard by using the OHP will be described.

Since the work schedule / safety instruction sheet has a large number of items and lines as described above and cannot be displayed on the electronic blackboard, in the example shown in FIG. 3, the items are divided by 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, the screen of the work schedule / safety instruction document projected on the electronic blackboard is provided with keys for screen switching selection, processing mode selection, and the like.

In FIG. 3 (a), for example, numeral 41 is a page selection switching key, which switches the screen to the page of the selected number 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 projected on the electronic blackboard by the projection device. .

First, the writing mode is set by the processing mode selection key 45. This is performed by managing the screen projected on the electronic blackboard by the projection device by the data processing device and processing the coordinate values in the predetermined area where the writing is displayed to be the writing mode. That is, when one point in the predetermined area indicated as written is designated by the special input pen, the coordinate value is recognized by the electronic blackboard (coordinate input panel) and transferred to the data processing device. The data processing device recognizes that the coordinate value is the selection key of the writing mode from the state of the screen projected by the projection device, 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. 4, 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. 3B, the input area 4 together with the handwriting input window 47 is displayed.

When the company name is written in 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 as image data. By this processing, the company name input by handwriting is displayed as it is in the hatched area in FIG. Each item is written in this way.

As described above, the work schedule / safety instruction sheet is set, and the item deletion / insertion of the processing mode selection key 45 is performed.
The move and copy keys perform their respective processes on the data set for writing. In addition, the work schedule / safety instructions can be set by using a keyboard, reading the one stored in a storage card from a card reader, or reading a hard copy from an image scanner. There is no end.

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. 5 is a diagram showing an example of a screen in which the equipment schedule is projected on an electronic blackboard, and FIG. 6 is a diagram for explaining an example of storing image data.

The equipment schedule is used to enter the usage schedule of equipment such as cranes and work platforms for aerial work to manage the operation of the equipment. 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. As shown in Fig. 5 (a), (b), the small application example in which each equipment is exclusively used by each trader is shown.
(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.
These are the company name column of the specified position, the company name in the list is recognized by collating the coordinate values specified on the electronic blackboard with the position of the equipment schedule displayed on the electronic blackboard.
This is because it is processed. The same applies to equipment names,
For work days, a calendar and numeric keypad are displayed in the window. Also, in the scheduled use time column, by instructing the position of the start and end times of use,
The bars shown in (b) and (c) are drawn. Also,
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, an image is input from the image scanner such as a plan view of each floor. Then, it is displayed on the electronic blackboard 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. 6 shows an example of storing the image data in the memory. A management table for the image data α, β is provided, each image data is searched from this table, and the storage areas I1, I2 are obtained by the pointer. It is configured to fly to .... Further, each data area has an area for storing image data and an area for storing size and division information relating to the image data, and the coordinates X ₁₁ , Y ₁₁ → X ₁₂ , Y ₁₂ → ...
The partition information is defined by. Therefore,
Display this image data on the screen and quickly
When setting overtime, etc., by converting the coordinates of each section from the coordinates of the origin of the image data, it is possible to recognize which area when an input such as point designation is made.

Similarly, there is management of arrangement and delivery as a means for inputting an image and registering and using it. 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 embodiments, the system configuration including the electronic blackboard, the electronic OHP, and the liquid crystal display tablet has been shown, but it goes without saying that a plurality of units may be connected to each of them. Moreover, although the case of using it for the meeting at the work place has been described, it may be similarly applied to the meeting for other meetings. A plurality of electronic blackboards and a card reader may be connected by a communication line, and the same data may be projected on each electronic blackboard to hold a meeting, so that the meeting can be performed simultaneously at different places. Furthermore, for example, it may be configured to be used for material management and obtain inventory from the history of materials coming and going in each section, or to collect the time of early exit and overtime work. Since a meeting can be handled by a combination of a key input device or an image scanner and an electronic blackboard, a card reader may not necessarily be provided as an input means.
