SDK-based automatic tracking system and method for hot rolling main rolling line operation monitoring screen

Abstract

The invention discloses an SDK-based automatic tracking system for hot rolling main rolling line operation monitoring screen and its control method. Host, L2 computer, L1 control PLC, network relay, set-top box, monitor. The L2 computer sends the strip steel information to the L1 control PLC in each monitoring area. The L1 control PLC determines the screen number to be displayed according to the abnormal information of production and equipment and the position information of the strip steel, and sends it to the set-top box through Ethernet for automatic switching. Only one of the multiple monitoring pictures is displayed on the monitor. Through the automatic tracking of the monitoring screen of the hot rolling main rolling line, the screen that the operator pays attention to in different processes becomes one, which greatly reduces the fatigue of the operator frequently looking up and down, and effectively improves the labor intensity of the operator.

Description

technical field [0001] The present invention relates to the field of industrial TV monitoring of hot-rolling main rolling line operation platform, and more specifically, relates to an SDK-based automatic tracking system for hot-rolling main rolling line operation monitoring screen and a control method thereof. Background technique [0002] In iron and steel enterprises at home and abroad, the production operators of the hot rolling main rolling production line concentrate on the operation of the main operation table, and monitor the equipment movement and production process of each part of the operation line through industrial TV on site. The current industrial TV uses a digital camera, and the video signal enters the video control host through the optical fiber, and then sends it to the operation console through the network. According to the number of camera monitoring points, the corresponding industrial TV screens are arranged on the console. Because there are many monito...

Problems solved by technology

In each monitoring area, the images that the operator pays attention to change with the change of the position of the head and tail of the strip. The current layout of the monitors lists the images of each monitoring point in each monitoring area, and erects a monitor at each monitoring point. The large-screen industrial TV displays all the images of each monitoring point to the operator. Due to the high installation position of the large-screen monitor, the operator has to keep looking up at different industrial TV screens, and at the same time, the operator has to look down from time to time. The HMI screen data on the platform and the buttons and handles of the control console, the current monitoring method has seriously aggravated the operator's operational fatigue and has a great impact on production and operation efficiency

[0005] In view of the large number of monitoring points at present, there is a black screen technology for industrial TV screens in the prior art. However, this technology cannot solve the problem that operators often look up to see different industrial TV screens hanging on it, nor can it solve the visual and cervical fatigue of operators. Therefore, there is an urgent need to develop a special technology related to industrial TV screens and production processes to accurately and automatically push the monitoring screens that operators care about in different processes to the operators, so as to reduce the monitoring work of the operators of the main hot rolling line. Intensity, to achieve the effectiveness of industrial TV picture display
