The monitoring device can continuously monitor states of steel wire core threads in the conveyer belt with a clamped core of a steel wire in real time.
Description
One. technical field
The present invention relates to a kind of device for monitoring lateral broke of steel wire enhanced conveying belt, especially the mine device for monitoring lateral broke of steel wire enhanced conveying belt.
Two. background technology
Steel cable sandwich load-transfer device is a kind of of Large Scale and Continuous transportation device, and this load-transfer device causes joint dislocation elongation between steel cable heart yearn fracture in the load-transfer device or steel cable heart yearn because of long-term use.If untimely processing can cause the transferring adhesive tape fracture accident.For preventing the generation of above-mentioned accident, more satisfactory measure is that the state of the steel cable heart yearn in the load-transfer device is monitored continuously in real time.
Chinese patent 89108052.X has put down in writing a kind of device of mine with the strong conveyer belt cross break that be used to monitor.Its principle is that the X-ray bundle from x-ray source passes and operatingly is mapped on the one-dimensional array of being made up of photodiode after sending defeated band, becomes electric signal at this converting optical signals that will contain the image pixel of steel cable heart yearn state.This electric signal is transferred in the image collection card after amplifying, gather and converting digital signal to, so that see the continuous real-time image of the steel cable heart yearn in the load-transfer device on monitor screen, thereby realizes the real-time continuous of load-transfer device is monitored.
Yet above-mentioned patent only limits to according to described principle described monitoring device be made a kind of preliminary design.Because this preliminary design is imperfection very still, so can not be used to monitor the state of steel cable heart yearn practically.Described imperfection part mainly is: the collection of the electric signal that will be converted to by the photodiode one-dimensional array, amplify, be processed into computing machine acceptable signal, and will this treated signal be transferred to and be arranged on nearby or computing machine does not at a distance provide the concrete means that can implement as yet.
Three. summary of the invention
Therefore, the object of the present invention is to provide a kind of device that can be used for lateral broke of steel wire enhanced conveying belt is carried out continuous real-time monitoring.
Describe the present invention in detail below by accompanying drawing, wherein:
Fig. 1 is the functional block diagram of apparatus of the present invention;
Fig. 2 is the pie graph of the X ray dash receiver among Fig. 1;
Fig. 3 is the pie graph of the control part on the spot of the pixel control desk among Fig. 1;
Fig. 4 is the pie graph of the long line transmission control part of the pixel control desk among Fig. 1;
Fig. 5 is the receiving unit pie graph of the long line transmission signals of the image processing plate among Fig. 1;
Fig. 6 is the receiving unit pie graph of the transmission signals on the spot of the image processing plate among Fig. 1.
State below device for monitoring lateral broke of steel wire enhanced conveying belt of the present invention, this device is provided with The x-ray source of an energy continuous operation, such as, B140 type x-ray source, it is placed in fortune One side of the conveyer belt in the row, the X ray that this x-ray source sends is set to after passing this conveyer belt Receive in the X ray dash receiver of transportation with the corresponding position of the other side. Described X ray dash receiver bag Draw together by photoelectric tube, such as a dimension array of S3 803 or S3804 formation; A preamplifier; A low pass filter; A simulation switch; An integral amplifier, a common mode inhibition electricity Road and an address decoder. What a dimension array that is made of photoelectric tube sent is comprising conveyer belt The signal of telecommunication of steel rope core line chart pixel send after processing through preamplifier amplification, low pass filter Simulation switch to by address generator control is collected in order, and the signal that collects is through integration The amplifier amplification is sent to pixel control plate by common mode rejection circuit.
Be sent on the pixel control plate through the simulation signal that common mode rejection circuit was processed. This pixel control Plate comprises simulation signal preprocessor, mould/number conversion circuit and address generator, from X ray The image pixel simulation signal of dash receiver amplifies then through analog-to-digital conversion through the simulation signal preprocessor Produce parallel image pixel data signal, this signal can be to transmit or long distance transmits on the spot Mode is transferred on the interior image processing plate of microcomputer. When transmitting on the spot, this signal directly passes past Image processing plate in the microcomputer; If when growing Distance Transmission, the parallel image pixel that is transmitted Data signal is transformed into serial image pixel signal through parallel-to-serial converter, again with control signal After synthesizing with door, become the data flow of serial.
This serial data stream is transported in the image processing plate in the microcomputer, in this this serial data stream quilt Resolve into data signal and control signal.
When receiving the signal that transmits on the spot, the image processing plate has only differential acceptor circuit, control signal producer and pair of pages memory work, to become the digital signal that microcomputer can receive from the pair of pages memory that the signal that the parallel image pixel digital signal of pixel control desk is sent through differential acceptor circuit and suspension control signal producer is controlled, so that on telltale, show in real time continuously.
And when receiving the described serial data stream that transmits through long distance, comprising serial/parallel control circuit producer and deserializer on this image processing plate, this producer comprises crystal oscillator, binary pair, with door and frequency divider.The above-mentioned serial data described serial/parallel control circuit of flowing through decomposites the clock signal, written request signal and the line synchronising signal that are used to control and parallel image pixel output signal, the situation of these signals when transmitting on the spot is identical, differential acceptor circuit and the suspension control signal producer signal that the send pair of pages memory controlled of image pixel output signal that should be parallel in the image processing plate becomes the digital signal that microcomputer can receive, so that show in real time continuously on telltale.
Device for monitoring lateral broke of steel wire enhanced conveying belt of the present invention can be monitored with the operation of the speed of 4m/s continuously in real time, and width is the load-transfer device of 0.8-1.4m; And the actual state of the steel cable heart yearn in the load-transfer device is presented on the screen; Can carry out intensity and joint elongation calculating according to the image that collects, report to the police when exceeding standard, and can deposit image and the result of calculation that collects in data bank so that search and analyze in the future according to result of calculation.Owing to possess above-mentioned functions, monitoring device of the present invention can carry out real-time monitoring continuously to the possibility of lateral broke of steel wire enhanced conveying belt reliably.
