Abstract
The invention relates to a four-camera two-terminal type boiler drum water level industrial television monitoring system. The four-camera two-terminal type boiler drum water level industrial television monitoring system obtains images of boiler drum double-color water level gauges through cameras and carries out monitoring and processing. The four-camera two-terminal type boiler drum water level industrial television monitoring system is characterized in that for a boiler drum provided with the double-color water level gauges at the left side and right side respectively, two cameras are installed near each double-color water level gauge, one of the two cameras is a fixed focus camera used for automatic image identification of the corresponding double-color water level gauge, the other of the two cameras is a zooming camera used for monitoring the corresponding double-color water level gauge by an operator, and each drum is provided with four cameras in total; for the boiler drum provided with the double-color water level gauges at the left side and right side respectively, a computer used for automatic image identification of the corresponding double-color water level gauge and a monitor used for monitoring the corresponding double-color water level gauge by the operator are respectively provided; the height values, obtained by the image processing computer, of the double-color water level gauges can communicate with a DCS system in a serial communication mode or an Ethernet communication mode or an AO signal output mode.
Description
Technical field
The present invention relates to industrial measurement and control field, be specifically related to a kind of four-head two tail formula boiler drum level industrial television monitoring systems.
Background technology
In service in power plant, steam water-level is in vital status, if drum level measurement error is easy to cause the heavy losses that cannot retrieve, therefore power department has been put into effect multiple regulation and standards based on steam water-level:
1) the < < of State Power Corporation issue prevents that in 25 important requirement > > of electrical production major accident, Section 8 major accident is exactly steam water-level full water and lack of water accident.
2) State Power Corporation is specially for drum level measurement has been issued < < station boiler steam bag level measuring system configuration, installation and the some regulation > > of use
But in present stage, the measuring principle of steam water-level is not too large improvement still, the main reliability that relies on increase differential pressure transmitter quantity to increase measurement, there is risk in this undue dependence single-measurement principle itself.
On the other hand, in drum level measurement, blindly introduce novel or unexamined metering system, have larger risk.
Summary of the invention
In view of the above-mentioned problems in the prior art, the object of the invention is to solve the integrity problem of boiler drum water level measurement, provide a kind of accuracy higher, the boiler drum level industrial television monitoring system that reliability is higher, function is more complete, thereby the progress of promotion China generating plant observation and control technology.
The present invention relates to a kind of four-head two tail formula boiler drum level industrial television monitoring systems, four-head wherein refers to four cameras, two tails refer to two monitor terminals (monitor or computing machine), it is by camera, to get the image of boiler-steam dome two-colour fluviograph, and monitors and process.It is characterized in that:
1) for the each boiler-steam dome that a two-colour fluviograph is installed in left and right, two cameras are installed near each two-colour fluviograph, one is the cameras with fixed focus for two-colour fluviograph image automatic identification, another is the zoom camera that monitors two-colour fluviograph for operations staff, and every drum arranges four cameras altogether.
3) for the each boiler-steam dome that a two-colour fluviograph is installed in left and right, a computing machine for two-colour fluviograph image automatic identification is set respectively, and for operations staff, monitors the monitor of two-colour fluviograph.
3) for the boiler-steam dome that a two-colour fluviograph is only installed, two cameras are installed near two-colour fluviograph, one is the cameras with fixed focus for two-colour fluviograph image automatic identification, another is the zoom camera that monitors two-colour fluviograph for operations staff, and every drum arranges two cameras altogether.
4), for the boiler-steam dome that a two-colour fluviograph is only installed, a computing machine for two-colour fluviograph image automatic identification is set respectively, and for operations staff, monitors the monitor of two-colour fluviograph.
5) the two-colour fluviograph height value that pattern process computer obtains can be by serial communication, and ethernet communication and three kinds of modes of AO signal output and DCS system communicate.
The advantage that the present invention has and beneficial effect are: the four-head two tail formula boiler drum level industrial television monitoring systems that the present embodiment provides are that a kind of accuracy is higher, the boiler drum level industrial television monitoring system that reliability is higher, function is more complete, will improve the reliability of boiler drum water level measurement, thereby promote the progress of China's generating plant observation and control technology.
Accompanying drawing explanation
Fig. 1 is the system diagram of one embodiment of the invention;
Embodiment
The present invention is further illustrated with specific embodiment below with reference to accompanying drawings.
As shown in Figure 1: a kind of four-head two tail formula boiler drum level industrial television monitoring systems of the embodiment of the present invention, comprise focusing image recognition camera, zoom camera, pattern process computer, monitor for image automatic identification.
The image pattern process computer that can monitor two zoom cameras by monitor can obtain two images that focus image recognition camera, and carries out image processing, and the result that gets the height value image processing of two-colour fluviograph sends to DCS system
Finally it should be noted that: above-described each embodiment, only for technical scheme of the present invention is described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record previous embodiment is modified, or to wherein partly or entirely technical characterictic be equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
