Abstract

A portable camera controller for use with a pipe inspection system is disclosed. The controller may include an onboard display, USB ports, wireless capability, and a built-in transmitter for energizing a pipe-inspection cable for tracing purposes. The camera controller may be configured to support auto-logging and automatic report generation of pipe inspection operations and associated locating operations. The camera controller may be self-grounding using conductive and/or capacitive grounding circuits and an associated transmitter may be used without a separate grounding stake through use of the conductive and/or capacitive grounding circuits.

Claims

1. A camera controller, comprising:

a base assembly to mechanically couple the camera controller to a hidden or buried pipe inspection system that includes a video push-cable and a camera head coupled to the video push-cable;

a user interface panel disposed on or within the base assembly;

an electronics module electrically coupled to the user interface panel including programmable electronic circuitry for;

receiving control input signals from the user interface panel upon a user actuation and providing, responsive to the received input signals, control data to the pipe inspection system camera head to control video capture operation; and

receiving one or more pipe inspection output video signals from the pipe inspection system camera head and storing data corresponding to the pipe inspection output video signals in a non-transitory memory;

a transmitter lug; and

an internal transmitter for generating a signal at at least a single frequency to be coupled onto the video push-cable via the transmitter lug to generate corresponding magnetic field signals for detection by an associated utility locator.

2. The camera controller of claim 1, wherein the electronics module includes additional electronic circuitry to provide the data corresponding to the pipe inspection output signals to an external electronic computing system.

3. The camera controller of claim 1, wherein the pipe inspection system includes a cable reel drum assembly.

4. The controller of claim 1, further comprising a Universal Serial Bus (USB) hub coupled to the electronics module to send and/or receive data associated with a pipe or other cavity being inspected.

5. The controller of claim 1, further comprising an electrical connector coupled to the electronics module for receiving signals from a system cable connected to the pipe inspection system.

6. The controller of claim 1, further comprising a wireless communication module coupled to the electronics module for sending and/or receiving wireless communication signals.

7. The controller of claim 1, further comprising a hub or router configured to wirelessly send and/or receive information from the pipe inspection system.

8. The controller of claim 7, wherein the information provided from the hub or router includes image, audio, and/or video data.

9. The controller of claim 1, wherein the transmitter generates a signal at a plurality of frequencies to be coupled onto the associated pipe inspection push-cable through the transmitter lug.

10. The controller of claim 1, wherein the camera controller includes one or more of a frame, feet, and a casing, and wherein the frame, the feet, and/or the casing are positioned on the camera controller to provide a grounding connection between the transmitter and a ground surface when the camera controller is placed on the ground surface.

11. The controller of claim 1, further including a microphone, wherein the electronics module receives an audio signal from the microphone, associates the audio signal with the pipe inspection output signals, and stores the audio signal and the pipe inspection output signals in a non-transitory memory.

12. The controller of claim 11, wherein the processing module is programmed to integrate the pipe inspection output signals, positional data provided from a positional sensor, and the audio signal and store the resulting data in the non-transitory memory.

13. The controller of claim 1, wherein the camera head includes a camera and a high-speed data link, wherein the camera is equipped with one or more of orientation, movement, and positional sensors.

14. The controller of claim 13, wherein the camera includes a microphone.

15. The controller of claim 1, comprising one or more stepped USB connectors.

16. The controller of claim 15, further comprising a sealed cover for the one or more stepped USB connectors.

17. The controller of claim 1, further comprising a joystick.

18. The controller of claim 17, wherein the joystick receives one or more of user inputs for traction manipulation, cursor movement, and image manipulation/articulation and provides corresponding outputs to the electronics module.

19. The controller of claim 1, further comprising a magnetically sensed user interface device (UID).

20. The controller of claim 1, further comprising an internal battery;

wherein the internal battery is configured to be charged from an external battery or external power supply.

21. The controller of claim 1, further comprising a lid element and a magnetic switch disposed on or within the lid element to control power actuation responsive to the a lid element open or closed position.

22. The controller of claim 1, further comprising a hood element.

23. The controller of claim 22, wherein the hood element is removable.

24. The controller of claim 23, wherein the hood element is restrained using a frictional surface contact.
