Abstract
An intelligent cable storage drum system for use in a pipe inspection system is disclosed. The system may include a cable storage drum, a video push-cable removably disposed on the cable storage drum, the video push-cable having a proximal end and a distal end, a video camera head having a camera output for providing analog or digital images or video output signals, and a transceiver module operatively coupled to the camera output for receiving the analog or digital images or video output signals and sending the received signals to a remote receiver.
Claims18
An intelligent cable storage drum system for use in a pipe inspection system, comprising:
- a cable storage drum;
- a video push-cable removably disposed on the cable storage drum, the video push-cable having a proximal end and a distal end;
- a video camera head having a camera output for providing analog or digital images or video output signals;
- and
- a transceiver module positioned within the cable storage drum operatively coupled to the camera output for receiving the analog or digital images or video output signals and sending the received signals to a remote receiver, wherein the transceiver module is at least one of a WiFi or LAN hub, node, or base station.
A method of providing digital video signals in a pipe inspection system, comprising:
- generating, in a video camera head operatively coupled to a video push-cable, a digital video signal;
- providing the digital video signal to a digital transceiver, wherein the transceiver is at least one of a WiFi or LAN hub, node, or base station;
- modulating, in the digital transceiver, the digital video signal using QAM modulation;
- coupling the QAM modulated digital video signal to a wired conductor disposed in the video push-cable;
- receiving the QAM modulated digital video signal from the video push-cable at a camera control unit (CCU);
- demodulating and extracting the digital video signal in the CCU;
- and
- storing the extracted digital video signal in a non-transitory memory of the CCU.
