Application study of an SPT chart on the drill rig s torque-rotating speed control system;

adapted the SPT chart as the control rules, with the application of data fusion, the method of the drill s detection, the bucket s protection and its power intelligent match are given based on data fusion, and the reformation is done with the use of double—hydraulic—control direction valve.

Based on the date structure of SPT graphic file and BMP image file and the research of translating SPT graphic file into BMP image file ,the compression of SPT graphic file was analyzed.

A method for the uncertainty analysis of measurement of electromagnetic parameters by employing the flow chart of error transfer;

Online hand-sketched flow chart recognition based on geometric features;

Design and implementation of equipment management system based on flow chart

In this paper, the author introduces correlative computing method of Kriging, compiles flow diagram of the Kriging algorithm based on Windows, and puts forward methods of improving the Kriging algorithm.

The authors also introduce the flow diagram of part of control procedure of the system.

The author proposes a test procedure of gate control system,and gives a flow diagram of the function test.
