Title:
ABSENCE PREVENTING DEVICE FOR GATHERED DATA
Document Type and Number:
Japanese Patent JP3424710
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To make it possible to generally connect even a data processor which is slow in arithmetic speed by providing a mechanism which prevents gathered data from being discarded.
SOLUTION: This device has an output buffer 22 which temporarily store a measuring signal inputted from a signal input part 21 as output data, a communication input/output part 23 which sends the output data stored in the output buffer 22 to a data processor 30, and a data gathering control part 25 which performs operation for converting the measuring signal into the output data in cycles determined by a timer 24 and controls the time when the communication input/output part 23 sends the output data. An output data number management part 26 is provided which outputs a stored area of the output buffer 22 to the data processor through the communication input/output part 23 and the information in the stored area sent from the output data number management part 26 is inputted; when the output data stored in the output buffer 22 exceeds the storage capacity or is expected to exceed it, absence of the gathered data is displayed to prevent the data from being absent.
