Abstract
The present invention provides a system for recording valve actuation information that enables to figure out the actual operation condition of each individual valve without checking plural valves individually, and the valves do not have to be wired, and the structure of the system is simple.The present invention is a system for recording valve actuation information comprising a valve, detecting means for detecting actuation of said valve, a RFID tag affixed to said valve and recording the valve actuation information detected by said detecting means, and a terminal for reading out the valve actuation information detected by said detecting means, wherein said RFID tag searches said terminal by intermittently transmitting a radio wave, wherein said RFID tag transfers the valve actuation information recorded in said RFID tag to said terminal when said RFID tag detects said terminal.
