Pipeline inspection apparatus and method using radio frequency identification and inertial navigation
First Claim
1. A method for inspecting a pipeline comprising,providing an inspection device to collect information relevant to the maintenance of the pipeline,said device including an inspection device having an RF transceiver capable of receiving identity information from a radiofrequency identification device (RFID),an inertial navigation unit capable of generating three-space position information,a processor capable of synchronizing identity information from a RFID with position information;
- anda section of pipe having a RFID with identity information for the section of pipe mounted on the wall of the pipe;
wherein said method further comprises configuring the RF transceiver of the inspection device to receive identity information from an RFID associated with a section of pipe;
introducing the inspection device into an access point in a pipeline containing a section of pipe having a RFID;
generating three-space position information indicative of the position of the inspection device in the pipeline;
collecting data from the RFID as the inspection device travels through the pipeline; and
synchronizing the identity information of the RFID associated with a section of pipe and the position information system of the inertial navigation unit.

Abstract
A pipeline inspection device, for example a pipeline inspection gauge or pig, is configured for inspecting a pipeline. The pipeline includes a plurality of pipes of varying orientations and a radio frequency identification device (RFID) provided on each pipe. Each RFID contains information indicative of the identity of each respective pipe. The inspection device includes a RF transceiver configured to receive the identity information from each RFID; an inertial navigation unit configured to generate three-space position information indicative of the position of the inspection device in the pipeline; and a processor configured to synchronize the identity information of each RFID with the position information to determine a three-space location of each pipe in the pipeline. A method of inspecting a pipeline that has a plurality of pipes includes collecting identity information indicative of the identity of each pipe; generating three-space position information indicative of the position of each pipe; and synchronizing the identity information and the position information.
