Abstract
PURPOSE:To detect a condition change for the large quantities of data at a short cycle and to attain the addition of a condition change time at high accuracy and at high resolution by performing the condition change detection processing of processing data using a receiver. CONSTITUTION:To a receiver 2 constituting a plant supervisory equipment, a preceding data buffer 22 to hold the received data of last time, a comparing means 23 to compare the contents of the preceding data buffer 22 with the contents of an input buffer to hold the latest data, and a timer 25 to give the condition change time to the data, whose condition change is detected by the comparing means 23 are added. Consequently, by detecting the condition change of the received data, adding the condition change time by means of a receiver 7, and distributing the processing, the processing in a supervising processor 8 can be reduced. Thus, even when the large quantities of data are inputted, the condition change of the entire data is detected at the short cycle, and the addition of the condition change time can be attained at the high accuracy and at the high resolution.
