PROCESS OF REMOTE TEST AND DIAGNOSTICS OF STATE OF STRUCTURE OF PIPE-LINES AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 2000 - IPC

Abstract RU 2146810 C1

FIELD: instrumentation. SUBSTANCE: invention can be used to test state of structures of pipe-lines, specifically, gas and oil pipe-line, pumping stations, collectors and so on in seismically unstable areas, in zones of unstable ground and permafrost. Process is based on remote polling of transmitters located in diagnosed points of tested objects. Central test point sends coded interrogation signal to measurement units. Measurement information is transmitted to central test point by measurement unit whose own code matches code of interrogation signal. EFFECT: increased timeliness of monitoring and expanded application field of process. 2 cl, 1 dwg
