MONITORING DEVICE AND MEASUREMENT DATA SUM-UP METHOD USED FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a monitoring device capable of easily and normally outputting the total of data without the need of complicated arithmetic operations.;SOLUTION: A counter data reception part 2 receives counter data measured in a data measurement part 1. A previous time counter storage part 3 preserves the counter data received in a previous time, an internal counter storage part 4 stores internal counter data and a difference upper limit value data storage part 5 stores difference upper limit value data for judging whether or not they are abnormal data. A counter data comparison part 6 compares the received counter data with the counter data of the previous time, compares the arithmetic result with the difference upper limit value data, judges whether or not they are normal data and updates the counter data of the previous time to the received counter data. An internal counter updating part 7 adds the counter data judged as normal to the internal counter data and a data sum-up part 8 sums up the internal counter data at every constant cycle.;COPYRIGHT: (C)2001,JPO
