Abstract

A work area setting and managing system which enables a operator to plan and manage work in a work area and set and store the work area at just the mobile work machine side at the work site is provided. The system is applied to a mobile work machine 11 performing land mine disposal work in the work area and provided with a GPS 3D position finding system and a tablet computer 62 having a display unit 63, input unit 64, and memory 65. This system is provided with a first means for displaying a work monitor screen 90 on a screen of the display unit, a second means for displaying a symbol of the mobile work machine on the work monitor screen based on positional coordinates of an attachment of the mobile work machine obtained by the GPS 3D position finding system, and a third means for preparing a work area based on an input operation of a operator using as the origin the symbol displayed on the work monitor screen and displaying a work area block model showing the work area.

Claims

1. A work area setting and managing system for a mobile work machine performing predetermined work in a set work area and provided with a GPS 3D position finding system and a computer having a display unit, input unit, and memory, characterized in being provided with

a first means for displaying a work monitor screen on a screen of said display unit,

a second means for displaying a symbol of said mobile work machine on said work monitor screen based on positional coordinates of an attachment of said mobile work machine obtained by said GPS 3D position finding system, and

a third means for preparing a work area based on an input operation of an operator using as the origin the symbol displayed on said work monitor screen and displaying a work area block model showing said work area,

wherein work information relating to said work area is set and managed at just the mobile work machine side.

2. A work area setting and managing system as set forth in claim 1, characterized in that said memory stores a work monitor screen preparation program, and said work monitor screen preparation program includes functional parts for realizing said first means, said second means, and said third means.

3. A work area setting and managing system as set forth in claim 1, characterized in that said memory stores a pre-work start object file, reads out on said pre-work start object file on said display unit at the time of start of said predetermined work, has obtained dimensional data relating to the range of the work area for the work input through said input unit, and determines the work area based on the dimensional data.

4. A work area setting and managing system as set forth in claim 1, characterized in that said memory stores a post-work completion object file and automatically stores work information in said post-work completion object file after work in said work area is ended.

5. A work area setting and managing system as set forth in claim 1, characterized in that said memory stores mesh status management information, and said work area block model is stored and expressed by a mesh model.

6. A work area setting and managing system as set forth in claim 5, characterized in that said work area block model displayed on said work monitor screen is expressed by a mesh model, and said work area block model displayed by a mesh is displayed color-coded in accordance with the work status of each mesh.

7. A work area setting and managing system as set forth in claim 1, characterized in that said work area block model is displayed by setting an origin of said work area as any origin in four directions from the position of said symbol.

8. A work area setting and managing system as set forth in claim 1, characterized in that in said work area displayed on said work monitor screen, poles are set at the four corners of an area where said predetermined work has been completed to specify a work completion area.

9. A work area setting and managing system as set forth in claim 1, characterized in that said mobile work machine is a land mine disposer, and said predetermined work is land mine disposal work.
