A New On-site and On-line Auto-calibration Scheme for Large-size Measurement and Control System

摘要

A new on-site and on-line auto-calibration scheme for large-size measure and control system is proposed in this paper, to resolve the problem that it is difficult to calibrate the measuring parameters in medium-size or large-size environment measure and control system for many sensors' nodes spreading widely. Then the paper discusses the necessity to calibrate the system, and designs a necessary device, which is called portable on-site and on-line temperature-measuring calibration meter, to implement this scheme. The calibrator's software-frame and operating steps have been demonstrated in the paper. The scheme helps calibrating multi-channel parameters quickly, conveniently and automatically in the large-size measure and control system.
