INSPECTION, AND OPERATING AND MONITORING SYSTEM FOR INSTRUMENTATION FACILITY INSTALLED IN PLANT

摘要

PROBLEM TO BE SOLVED: To provide an inspection system which makes it possible to set the opening of a valve installed in a plant, to check measuring instruments such as a manometer and a flowmeter, including the valve zero adjustment and transmitter adjustment only by field operators.;SOLUTION: A personal computer 7 is connected through a gateway 11 to a LAN 9 which connects an operator station 2 and a control station controlling instrumentation facilities to each other and monitoring the state of the instrumentation facilities. The personal computer 7 and a handy terminal 12 are allowed to communicate with each other interactively through a radio adapter 8. Then the instrumentation equipment such as a manometer is checked by adjusting the valve to zero by closing the valve 4 by input to the handy terminal 12, adjusting the transmitter, setting the opening of the valve 4 and detecting the pressure, etc., at that time.;COPYRIGHT: (C)2002,JPO
