Abstract
The invention discloses a muzzle smoke testing device and method. A laser transmitting and receiving system is arranged in front the muzzle in a vertical direction, a laser screen illuminator (1) and a laser receiver (2) are mounted on both sides of the front of the muzzle; an FPGA based visual signal collector (3) is connected with the laser receiver; a second set of laser transmitting and receiving device is arranged on the position having a distance d from the first set of laser transmitting and receiving device; a signal processing module (4) and a PC machine (5) are arranged 2 meters away behind the muzzle. At the same time of muzzle launch, the laser screen is used to collect the smoke concentration and shape change; the laser illuminators (1) and(6) emit laser, and the laser receivers (2) and (7) receive the laser light intensity value; the signal processing module (4) processes the time-varying signal acquired by the visual signal collector (3), uploads the signal to the PC (5), and calculates the smoke concentration change value according to the change of light intensity. The invention has the following advantages: synchronous measurement of muzzle smoke concentration and shape curve.
Description
Technical field
The present invention relates to a kind of gun muzzle smog proving installation, belong to detection field.
Background technology
Generally, the process on fire of fire is with cigarette, heat, light three kinds of products of combustion.At Initial Stage of Fire, because temperature is lower, material many places in the stage of glowing, so produce a large amount of smog.Smoke detector utilizes this feature and develops, it is also referred to as smoke fire detector, smoke alarm, smoke detector, Smoke Detector and cigarette propagated sensation sensor, is the change of detection position smokescope to be converted to electric signal realize a kind of device of warning object.Smoke detector is mainly used in fire-fighting system and safety-protection system, has highly sensitive, reliable and stable, low-power consumption, the feature such as attractive and durable, easy to use, can to the fire detector of visible or sightless smoke particle response.Because smoke detector is highly sensitive, therefore in installation process, need debugging, the inspection after installation and the course of receiving bother very much, waste time and energy.
Summary of the invention
The invention discloses a kind of gun muzzle smog method of testing, laser transmitting-receiving system is set up in vertical direction before gun muzzle, laser light curtain illuminator (1), laser pickoff (2) are set up in the front both sides of gun muzzle respectively, visual signal collector (3) based on FPGA connects laser pickoff, laser transmitting-receiving device is overlapped in distance first set laser transmitting-receiving device d place's erection second, and signal processing module (4), PC (5) are placed in beyond 2 meters, gun muzzle rear; While gun muzzle is launched, utilize laser light curtain to gather smokescope and change of shape simultaneously, laser hole drilling illuminator (1) and (6) Emission Lasers, laser pickoff (2) and (7) receive laser light intensity values, the time varying signal that signal processing module (4) process visual signal collector (3) gathers, upload to pc machine (5), ask for smokescope changing value according to light intensity change; Of the present invention have following advantage: gun muzzle smokescope, change of shape curve synchro measure.
Accompanying drawing explanation
Describe exemplary embodiment of the present invention in more detail by referring to accompanying drawing, above and other aspect of the present invention and advantage will become and more be readily clear of, in the accompanying drawings:
