Title:
INSTRUMENT AND METHOD FOR MEASURING FACILITY OPERATION STATE
Document Type and Number:
Japanese Patent JP3769420
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a new facility operation state measuring instrument which can accurately, easily, and automatically measure a continuance and an integrated physical value in various states of facilities and obtain various data needed to improve the operation efficiency of the facilities and save the energy.
SOLUTION: This facility operation state measuring instrument 1 is equipped with a physical quantity measuring means 3 which measures physical quantities for deciding the respective operation states of the facilities 10, a time measuring means 20, and an arithmetic processing means 21. The arithmetic processing means 21 decides the operation state of the facilities 10 according to the physical quantities measured by the physical quantity measuring means 3, the time measuring means 21 measures the continuance by the operation states, and the arithmetic processing means 21 integrates the continuance and the physical quantities in the continuance by the corresponding operation states.
