<P>PROBLEM TO BE SOLVED: To provide a valve operation information recording system of simple configuration which can grasp actual operating states of respective valves at a time without checking the plurality of valves individually, and does not require wiring or the like especially on the valve. <P>SOLUTION: The valve operation information recording system comprises the valve, a detection means for detecting operation of the valve, an RFID tag attached on the valve for recording operation information detected by the detection means, and a terminal for reading the operation information of the valve recorded in the RFID tag. The RFID tag transmits a radio wave intermittently to search presence of the terminal. When the RFID tag detects a signal of the terminal, the operation information of the valve recorded in the RFID tag is transferred to the terminal. <P>COPYRIGHT: (C)2009,JPO&INPIT |
