METHOD AND DEVICE FOR THE REMOTE MONITORING OF MANUAL VALVES FOR FLUID SYSTEMS SUCH AS, FOR EXAMPLE, THE NUCLEAR ISLAND OF A NUCLEAR POWER PLANT.

摘要

The invention relates to a method for the remote monitoring of manual valves (15) for fluid systems in the nuclear island of a nuclear power plant, a method wherein: the manual valves (15) are provided with a means (31) for detecting the open and closed positions thereof and with a first means (32) for the wireless communication of signals related to the position of each valve (15); a second signal communication means (35) is provided in the vicinity of the valve; local cable networks (36, 38) are provided, enabling received signals to pass through thick walls; and a means (40) for receiving and processing the signals after passing through said walls is provided in a monitoring room. The device according to the invention can obviously apply to all fluid systems comprising manual valves, the positions of which must be remotely monitored.
