A self-propelled, automated, autonomic grid crawler which, when attached
to a wire, moves along the wire to sense conditions of the wire. The grid
crawler includes a central processing unit (CPU), working memory, such as
random access memory (RAM), persistent money, such as read only memory
(ROM) and hard drive (HD), sensor electronics, a wireless interface, a
location device, such as a global positioning satellite (GPS) receiver,
motive power system, and a battery. The sensor electronics serves to
sense various types of faults. The CPU analyzes the data from the sensor
electronics using pre-analysis and pre-qualification algorithms, which
are stored in the HD. Depending on the results of the analysis, the CPU
transmits information to the central station, either directly or
indirectly via mounted docking devices, that potentially indicates a
fault, including the location of the fault as determined by the GPS
receiver. The pre-processing and pre-qualifying of the data at the
autonomic grid crawler limits the amount of data that needs to be
transmitted to the central station, thereby saving battery power.
