Abstract

A full-automatic discrete type drill rod diameter non-contact static-dynamic measurement instrument can be used for static-dynamic measurements of a drill rod diameter in mine exploration or oil drilling operations. The full-automatic discrete type drill rod diameter non-contact static-dynamic measurement instrument is composed of a diameter measurement sensor (1), a temperature sensor (2), a signal processor (3), a signal source (4), an amplifier (5), a single-chip computer (6), a liquid crystal display (7), a data transmission interface (8), a power source (9) and a keyboard (20). The full-automatic discrete type drill rod diameter non-contact static-dynamic measurement instrument can measure the diameter of a drill rod full-automatically, statically and dynamically in a non-contact mode, on one hand the diameter information of the drill rod can be displayed in the liquid crystal display, on the other hand the diameter information of the drill rod can be derived to a personal computer (PC) through the data transmission interface to facilitate the PC to sending operational orders to control the working status such as advance, retreat, stop and drilling of the drill rode, and thus automatic control of drilling operations is achieved.

Description

technical field [0001] The invention relates to an electronic measuring instrument, in particular to a discrete non-contact full-automatic static and dynamic measuring instrument for the diameter of a drill pipe. Background technique [0002] In prospecting or oil drilling operations, if the automatic control of drill pipes is implemented, information such as the thickness and quantity of downhole drill pipes, and the number of pipe collars used for connecting drill pipes with different thicknesses must be collected. Due to the complex operating environment, general optics, etc. The measurement method cannot meet the dynamic measurement requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-contact automatic static and dynamic measuring instrument for discrete drill pipe diameter, which provides technical support for the automatic control of drill pipe during prospecting or oil drilling. , so the pr...
