PROBLEM TO BE SOLVED: To properly and quickly facilitate a countermeasure to the generation of adnormality of a control equipment a through a central side monitoring device in a monitoring system for monitoring a control equipment provided at a job site by using an application shared sorfware, and sharing the same screen image with a job site side monitoring device and a central side monitoring device. SOLUTION: At normal times when abnormality is not generated in a control equipment 4, screen image data are transmitted a first job site side monitoring device 1 via a public line 3 to a second central side monitoring device 2. When an adnormality detection signal which indicates the generation of the abnormality of the control equipment 4 is obtained by a sequencer 16 of the first monitoring device 1, measured and monitored data indicating the operating state of the control equipment 4 are transmitted from the first monitoring device 1 to the second monitoring device 2, while the screen image data are interrupted. The second monitoring device 2 side searches for the cause of the abnormality and devises a countermeasure, based on the measured and monitored data and the screen image data. |
