Abstract

An automatic, electronically operated data collection and display system for a pipeline video monitoring device, and a method for collecting and displaying information on a pipeline with a video image. A plurality of data inputs are connected to the monitoring device for receiving information on the operating parameters of the device. The data inputs include an operator input. A control unit is connected to the data inputs and has an interconnected central processor, input/output control system, and graphics generation and video overlay system. Data outputs are connected to the input/output control.

5. The automatic data collection and display system of claim 4, wherein said input/output control means comprises a plurality of adapters constructed and arranged to interface the data input devices with said central processor.

6. The automatic data collection and display system of claim 4, wherein said processing means utilizes Computer Information Code and has program means for converting signals from the data input devices and from said operator input means into said graphic format for display.

7. The automatic data collection and display system of claim 6, wherein said program means for converting signals from the data input devices and from said operator input means into said graphic format comprises, consecutively, an update routine, a display routine, and a check-keyboard routine.

8. The automatic data collection and display system of claim 7, wherein said update routine converts data input device data output to said central processor from Computer Information Code to American Standard Code for Information Exchange.

9. The automatic data collection and display system of claim 8, wherein said display routine determines whether data input device data has been updated for display, determines the display format of the data input device data, and then displays the data input device data on the video monitor.

10. The automatic data collection and display system of claim 7, wherein said check-keyboard routine comprises a plurality of subroutines being accessible via said operator input means, said check-keyboard routine first determining whether said access has been made, whether said access is valid and then executing said subroutine.

11. The automatic data collection and display system of claim 10, wherein said subroutines include a preprogrammed menu of operator input remarks and a plurality of information display functions.

12. The automatic data collection and display system of claim 11, wherein said pre-programmed menu comprises a plurality of statements which are descriptive of common pipeline conditions and defects.

13. The automatic data collection and display system of claim 11, wherein said information display functions comprise means for adjusting the physical characteristics of the data input device data and said operator input remarks displayed on the video monitor.

14. The automatic data collection and display system of claim 1, wherein said means to overlay data converts signals from the data input devices to page format graphics and overlays said page format graphics on the video signal from the video camera for display on the video monitor.

15. The automatic data collection and display system of claim 14, wherein said means to overlay data comprises a graphics generation processor and a video overlay processor.

16. The automatic data collection and display system of claim 15, wherein the video camera and remote video monitor are a color camera and monitor respectively, and wherein said video overlay processor synchronizes color signals from the camera with color signals from color graphics from the graphics generation processor, said video overlay processor further having means to alternate video formats.

17. The automatic data collection and display system of claim 1, further comprising means to produce a hard copy of the video signal and said graphic format data received from the data input devices and from said operator input means, said hard copy including a video recording.

18. An automatic, data collection and display system for use with a pipeline video surveying device including a video camera which provides a video image of physical operating parameters, said system comprising:
