Embodiment Construction

[0037] An embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] FIG. 1 shows the configuration of a device control device (device status monitoring device) 100 according to an embodiment of the present invention. The device control apparatus 100 includes a central processing unit (CPU) 102 , an input unit 103 , a display unit 104 , a communication unit 105 , a main storage 106 , and an external memory 107 , which are interconnected by a bus 101 .

[0039] The CPU 102 reads the device control program stored in the external memory 107, expands it in the main storage device 106, and executes the program to control the operation of each component in the device control device 100 and also controls the controlled device 111 . The CPU 102 can also perform characterization by reading a program (logic execution program, logic update program, logic evaluation program) suitable for processing from the external memory 107 and ex...

Abstract

This invention refers to an apparatus and method for monitoring condition of a device by using sensors and a computer readable medium, wherein the apparatus including: a data collecting unit configured to collect sensor data; a monitoring executing unit configured to execute monitoring logics to obtain condition values corresponding each of the monitoring logics; an output unit configured to output the values corresponding to a monitoring logic selected by selection information; a distance index calculating unit configured to calculate a distance index between a distribution of values corresponding to selected monitoring logic and each of one or more distribution of values corresponding to each of one or more other monitoring logic; and an information updating unit configured to update the selection information to select one of the other monitoring logic when a number of monitoring logics having the distribution distant more than a first threshold from that of selected monitoring logic is greater than a first threshold or equal.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from prior Japanese Patent Application No. 2007-131755 filed on May 17, 2007; the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an apparatus and method for monitoring equipment status and a computer-readable medium storing a program for monitoring equipment status. Background technique [0004] To operate equipment safely and efficiently, it needs to be kept in good condition through maintenance work. Neglecting maintenance work can lead to loss of customers, as a cascade of failures and the like can reduce customer confidence in the equipment and in the worst case, lead to huge losses, such as the Schindler elevator accident. On the other hand, since repair work involves high costs, it is desirable to perform fixed repair work more efficiently and / or to reduce the frequency of temporary repairs while e...
