Description
Technical field
The present invention relates to a kind of, and monitoring system is blown out in the gas engine tempering based on Digital Image Processing, is mainly used in
Technical field of engines.
Background technique
Nowadays phenomenon is blown out in the generally existing tempering of gas engine." tempering " refer to combustion gas not yet enter cylinder before,
Burning or explosion occur in air inlet pipe；" blowing out " refers to that combustion gas is not burnt in the cylinder, and burning or explosion occur in exhaust pipe.
The phenomenon gently then smoulder in air inlet and exhaust piper is blown out in tempering, and high temperature damages air inlet and exhaust piper, heavy then formed in air inlet and exhaust piper
Explosion damages equipment, while endangering personal safety.Under normal circumstances, slight tempering is blown out to develop into seriously to be tempered quickly and be put
Big gun, it is necessary to the early early processing of discovery.Implementation monitoring is blown out to tempering at present and is primarily present following difficult point:
(1) slight tempering once in a while is blown out, and the temperature of air inlet and exhaust piper not necessarily increases, even if increasing, it is also desirable to which one adds
Thermal process will not show immediately, can not pass through temperature monitoring；
(2) no sound is blown out in slight tempering, can not be discovered experienced operator；Sound is blown out in serious tempering
It is larger, but the live noise jamming of engine operation is serious, is infeasible by sound transducer judgement；
(3) it is huge to be seriously tempered the brisance blown out, and the temperature in exhaust pipe is very high, general sensor is basic
It is unbearable, if monitored using sensor, cannot be mounted on inside air inlet and exhaust piper.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of solution gas engine tempering blows out asking of being unable to monitor
Topic, allows unit control system targetedly to take measures, and tempering is inhibited to blow out, or issues alarm, avoids safety accident
Monitoring system is blown out in the gas engine tempering based on Digital Image Processing occurred.
Monitoring system, including high temperature resistant height are blown out in gas engine tempering of the present invention based on Digital Image Processing
Pressure gate mirror, reflective mirror, high-definition camera and image processing equipment, high temperature high voltage resistant peephole and high-definition camera are separately mounted to protect
The both ends of protecting pipe, protection sleeve pipe one end connect snorkel, and the other end connects image processing equipment, and protection sleeve pipe and snorkel connect
Meeting place is high temperature high voltage resistant peephole, and protection sleeve pipe and image processing equipment junction are high-definition camera, is set inside protection sleeve pipe
Reflective mirror is set, between high temperature high voltage resistant peephole and high-definition camera, protection sleeve pipe is arranged reflective mirror at installation reflective mirror
For bending tube.
High-definition camera is responsible for the acquisition of air inlet and exhaust piper Intra pictures, and image is passed to image processing equipment and software.
Image processing equipment and software, image processing equipment are the microprocessor platforms such as industrial personal computer, PC machine, embedded control panel, generally
Run the operating systems such as Windows, Linux；Image processing software is in the professional machine such as Open CV, Halcon, VisionPro
The application program developed on the basis of device vision software library, is analyzed and processed the collected video of camera.Unit is normal
Be in air inlet and exhaust piper when work it is dark, when software monitors to some cylinder inlet and outlet mouth position have faint bright or flame
When, determine that the cylinder has occurred slight tempering and blows out；When software monitors to it is strong bright when, judgement has occurred serious tempering and puts
Big gun.
The high temperature high voltage resistant peephole is by concavees lens and convex lens group at material is quartz glass.Concavees lens increase
The observation scope of image in air inlet and exhaust piper, should reasonably adjust peephole concavees lens and focal length of convex lens understands air inlet and exhaust piper image
Projection on a mirror.
The reflective mirror is mounted on protection sleeve pipe bending part, and protection sleeve pipe bending angle is 90 °, reflective mirror setting angle
It is 45 °.
The protection sleeve pipe is made of stainless steel material.High temperature high voltage resistant peephole, reflective mirror, high-definition camera are risen solid
Fixed and protective effect.
Setting is flexible coupling in the protection sleeve pipe, is flexible coupling between reflective mirror and high-definition camera.It has been flexible coupling
To damping and heat-blocking action, effectively mitigate the influence of unit vibration and high temperature to high-definition camera.
The snorkel includes air inlet pipe and exhaust pipe.
The beneficial effects of the present invention are:
Based on Digital Image Processing, by the way of " seeing ", solves the problems, such as that tempering is blown out and be difficult to monitor, it can be timely
Accurately phenomenon is blown out in the tempering of feedback gas engine.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1, high temperature high voltage resistant peephole；2, reflective mirror；3, protection sleeve pipe；4, it is flexible coupling；5, high-definition camera；6, scheme
As processing equipment.
Specific embodiment
The present invention is described further with reference to the accompanying drawing:
As shown in Figure 1, monitoring system is blown out in the gas engine tempering of the present invention based on Digital Image Processing, wrap
High temperature high voltage resistant peephole 1, reflective mirror 2, high-definition camera 5 and image processing equipment 6 are included, high temperature high voltage resistant peephole 1 and high definition are taken the photograph
The both ends for being separately mounted to protection sleeve pipe 3 as first 5,3 one end of protection sleeve pipe connect snorkel, and the other end connects image processing equipment
