Slagging and coking monitoring device for boiler
The boiler slagging and coking monitoring device of image analysis is a comprehensive monitoring device combining multimedia technology, computer technology, digital image processing technology and industrial television technology. It carries out real-time monitoring of boiler slag discharge necking, can intuitively display the working conditions of slag hopper and slag fishing machine, and further process and analyze the monitoring image, effectively and reliably judge coking, automatically alarm and store video when coking is serious, and the image information is used as the basis for accident analysis. Using the latest dual CPU high-speed processor and multi-threaded parallel processing technology, the multi-channel monitoring, alarm, remote control and image processing speed more quickly and accurately. The device has novel design ideas, advanced technical means, superior performance, simple operation, accurate judgment of monitoring target state, intuitive and effective accident analysis means, and is accepted and put into use by more and more large, medium and small thermal power plants. It plays an important role in the operation monitoring of boiler slag discharge.
system composition
High temperature probe, automatic furnace mechanism, electrical control cabinet, hard disk video recorder, industrial control computer, display, air control system, signal cable and control cable.
Device function
Real-time display of slag falling status of boiler necking.
The high-temperature probe is a special periscential system designed by our company for slag and coke monitoring. It has the function of rotating in the circumferential direction and can monitor the coking conditions of the two positions of the necking and slag discharge mouth of the boiler above the slag hopper respectively.
The video image is converted into a digital image by the image acquisition card, which is displayed by the liquid crystal display, with multi-screen six-screen display, four-screen, two-screen display or six-screen display alone, and six-screen cycle display function.
Through the control of the upper computer, the remote control of the entry, exit or rotation function of the high temperature probe can be realized, that is, the mouse is used to click the corresponding button on the user operation page in the centralized control room to control.
The state of the probe can display various types of alarm signals, such as the state of the probe in place or over-temperature, wind pressure abnormal state. It can judge whether the video signal is interrupted due to the damage of the camera, and give the corresponding alarm signal. It can not only receive other field and data signals (such as temperature, pressure and other signals), but also make alarm judgment according to the limit value input in advance. The signal state, value and alarm signal can be displayed on the monitor screen in real time by video superposition technology.
Automatically determine whether the boiler necking is coking and send out alarm signals for the reference of operators, and automatically record 30 minutes of video before and after the accident, so as to facilitate the recall and coking cause analysis after the accident.
You can set the user ID and password, start the system, exit the system with password protection, no permission can not start, exit the system;
A multi-user level management system can also be used, that is, different users have different passwords and permission levels, can perform different operations on the system under the corresponding level of permission, and can record their operation information for each different user. so as to divide responsibility after the fact.
Alarm records can be classified and queried according to alarm time and alarm content, and operation records can be classified and queried according to operation time, operator and operation content. The system has a port for the print output device, which can be connected to the printer to print out the accident record report and the user operation record report as the reference data.
