Embodiment
Technical scheme of the present invention is further illustrated below in conjunction with specific embodiment.
See accompanying drawing 2, high speed bar rolling rolling line video analysis supervisory control system involved in the present invention, comprising three parts, is front end recording subsystem, data transmission sub-system, center monitoring subsystem respectively;
The quantity of described front end recording subsystem is 4,4 front end recording subsystems are separately positioned on 4 flying shear positions, each front end recording subsystem is primarily of high speed high-definition camera (adopt and capture the high speed camera that frame per second is 60 ~ 100 frames/second, 1280x1024 resolution), industrial computer, high brightness light filling equipment, industrial constant-temperature system composition; Described video camera is electrically connected with industrial computer, video camera by gather image information real-time Transmission to industrial computer; Described industrial constant-temperature system comprises air cooler or water cooling equipment, and dust cover, video camera and industrial computer are arranged in dust cover, dust cover is embedded in air cooler or water cooling equipment simultaneously, the severe operational environment such as high temperature, noise, dust or vibration is in often because rolling line is other, so carry out dust-proof temp-lowering by dust cover and air cooler or water cooling equipment to video camera and industrial computer, to ensure that it normally works, the system block diagram of this subsystem as shown in Figure 3;
The camera lens of front end recording subsystem exposes dust cover, and light filling equipment is arranged on dust cover outside; Camera lens aims at the cutting edge of every platform flying shearing machine, gathers image.Due to bar production, in the operation of rolling, along with residing stage difference is (by roughing, in roll finish rolling), the speed that bar runs on rolling line is accelerated gradually, its speed of service is by about 2 initial meter per seconds, to final 18 meter per seconds, so the time for exposure of the video camera of four front end recording subsystems also will adapt to its right flying shearing machine, according to the flying shearing machine in background technology, the time for exposure of the video camera of corresponding flying shearing machine 1 (i.e. the first operation flying shearing machine) is set as 5ms, the time for exposure of the video camera of corresponding flying shearing machine 2 (i.e. the second operation flying shearing machine) is set as 3ms, the time for exposure of the video camera of corresponding flying shearing machine 3 (i.e. the 3rd operation flying shearing machine) is set as 1ms, the time for exposure of the video camera of corresponding flying shearing machine 4 (i.e. the 4th operation flying shearing machine) is set as 0.5ms.
Described data transmission sub-system adopts all-optical network switching technology, namely whole system only carries out electric light, opto-electronic conversion at the data receiver of the industrial computer data output end of 4 front end recording subsystems and the management host of center monitoring subsystem, exists in the form of light all the time in all the other Internet Transmissions and exchange process.Namely the data receiver of the industrial computer data output end of front end recording subsystem and the management host of center monitoring subsystem is interconnected by optical add/drop multiplexer optical cable.The advantage adopting all-optical network to exchange is as follows: 1, message capacity is large: because the data acquisition amount of front end recording subsystem is larger, and kilomega network and above networking mode therefore must be adopted just to complete the work of transfer of data; 2, long transmission distance: because the equipment forming a rolling line in Bar Plant is many, cause production line longer, and traditional 6 class netting twines or surpass 5 class netting twines and wiring distance is had clearly limit, be not suitable for laying near rolling line, and use quartz can reach several kilometers as its transmission trunking distance of optical fiber of main material; 3, electromagnetism interference: have a lot of large power-consuming equipment in Bar Plant, the electromagnetic radiation intensity in workshop is higher, and the constituent material due to optical fiber is insulator, therefore not by the electromagnetic interference influence of the industrial electricity apparatus such as large power-consuming equipment and high-tension apparatus; 4 and optical cable also there is the features such as volume is little, lightweight, long service life, be well suited for using at this kind of industrial site of Bar Plant.
Described center monitoring subsystem comprises a management host (i.e. computer) and display, the data (picture data of video camera shooting) that the industrial computer that the management host of center monitoring subsystem exchanges real-time reception 4 front end recording subsystems by all-optical network transmits, and the picture data that video camera is taken is transferred to display display, realize real-time monitoring running status of process zone range devices each on steel rolling production-line and the shearing condition of bar being carried out to video.
Above to invention has been exemplary description; should be noted that; when not departing from core of the present invention, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection scope of the present invention.
