<p><P>PROBLEM TO BE SOLVED: To provide a state monitoring method, a state monitoring device, a state monitoring system and a computer program for easily deciding the state of an object to be monitored by quickly estimating the parameter of a model showing the relations of a plurality of data showing the state of the object to be monitored. <P>SOLUTION: This state monitoring device is configured to store a first data column constituted of N pieces of data showing the state of an object to be monitored and the first estimated value of a parameter, and to accept a second data column constituted of m pieces of data (S4), to prepare a third data column by adding the second data column to the first data column (S5), and to calculate the second estimated value of the parameter from the first estimated value and the third data column by using an arithmetic formula to easily calculate results to be obtained by repeating the calculation of a Kalman filter m times (S7), and to calculate a parameter L for executing the white test of residual columns between the data of the second data column and the estimation data to be calculated from the second estimated value (S8), and to decide the state of the object to be monitored based on the value of the parameter L (S9). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
