Abstract

The invention discloses a novel steel wire core conveyer belt detector for a mine, which is characterized by comprising a velocity sensor, an X-ray resource, a linear array receiver, a subordinate industrial computer and a superior industrial computer, wherein the X-ray resource, the linear array receiver and the velocity sensor are connected with the switch card of the subordinate industrial computer by a relay board; the X-ray resource exchanges data with the subordinate industrial computer in a serial port mode; the linear array receiver exchanges data with the subordinate industrial computer by optical fiber; velocity impulse generated by the velocity sensor is provided for the subordinate industrial computer; and the subordinate industrial computer exchanges data with the superior industrial computer via the Ethernet or the optical fiber. The 'rhythm' of the data acquisition of the invention can change along with the change of external input impulse so as to obtain the follow-up of the data acquisition frequency and velocity variation of the linear array receiver, the operation velocity of the conveyor belt can be detected in time, and influence on image acquisition by velocity perturbation can be reduced.

Description

Technical field: [0001] The invention is mainly used for non-destructive perspective detection of the steel cord conveyor belt. Background technique: [0002] The current line array receiver is used to detect the steel cord conveyor belt device. The detection premise of the line array receiver is to assume that the measured object passes through the imaging area of ​​the ray perspective system at a constant speed, and the line array receiver uses a certain frequency line by line. Record the value of the lightness and darkness of each line of the object, upload the data to the upper industrial computer, and then restore and display the single-line data combination to form an observable image. Because the steel cord conveyor belt in the coal mine is sometimes heavily loaded, sometimes lightly loaded or empty, the speed will inevitably fluctuate to a certain extent. In the existing linear array receiving and detecting device for steel cord conveyor belt, when the speed of the ...
