Modelling the Control System of Sensor Movement Mechanism of Logging Unit

This work addresses the issue of geological exploration and search of rich ore deposits. One of the effective methods is a use of logging principle, which consists of: a well is drilled with 25-35 cm diameter, then the well side face is studied, i.е. the ore percentage is determined on the well height. The logging unit specified in this work consists of a main stepper motor, reducer, winch and a shell with telescopic sensor. The sensor consists of ionizing radiation sources, proportional counter used for detector, preamplifier and a sensor movement stepper motor. A motor implements an important function, consisting of lowering and lifting of the logging instrument into the well. Therefore, a motor control function composition is discussed, the movement of which will reconcile with the movement of sensor motor. All software and control tools will be in the computer (laptop) with a digital converter. The task of creating a new logging unit, based on the use of massive material xray, as well as automation of all processes on this machine with the use of modern achievements of information technology and computer technology is relevant for the following features: creation of high technologies for solution of the tasks of exploration and prediction of mineral deposits within the priority of scientific and technological development of the mining and metallurgical industry of the Republic of Kazakhstan; the absence in Kazakhstan and the need to build a mobile logging unit with automated control and information processing system, based on the advanced method of well logging. The process of work covered a research on the development of a new method and technology of computer control and information processing of logging unit, an X-ray radiometrical logging unit mathematical model and control function was developed. The results of the study can later be used in creating automated mobile logging unit that can be used in mining metallurgical industry.
