Operation principle of the present utility model is as described below:
Laser instrument and galvanometer scanning system are positioned at sustained height, are provided with a beam shaping system between laser instrument and galvanometer scanning system, and described beam shaping system comprises convex lens and concavees lens, is used for Laser Output Beam is carried out beam-expanding collimation.
Laser instrument has carbon dioxide laser, ruby laser, semiconductor laser etc., and this specific embodiment adopts semiconductor laser, and the characteristics of semiconductor laser are advantages such as startup is fast, working stability, reliability height, the life-span is long, cost is relatively low.
Aspect the wavelength of laser instrument, common red laser (the reason of 630～650nm) little ruddiness poor visibility of owing to power, can not in air, form significantly light path, this specific embodiment adopts the green glow of 532nm as the guiding light beam, because 532nm just is in the comparatively responsive yellow green wave band of human eye, produces a very eye-catching light beam during laser works, can be found by the people easily, even in smog, also can form comparatively significantly light path.Such as power is that the green laser effective range of 20mW can reach 15 kilometers, finds that when it is tested in thick fog distance has 200 meters at least.
Be positioned at the galvanometer scanning system of sustained height with laser instrument, can control X-axis, the Y-axis trend of light, be used to control the scope of the light that laser instrument sends.Inject galvanometer scanning system after laser is through beam shaping system beam-expanding collimation, described galvanometer scanning system carries out the control of X-axis and Y-axis trend to incident laser, thus the sweep limits of control laser.
The laser projection that penetrates through galvanometer scanning system is a type, with the laser beam transformation pattern, need be in mask imaging system of galvanometer scanning system outer setting, described mask imaging system comprises the mask plate with Warning Mark, is used for output beam is formed indicator diagram.Warning Mark on the mask plate can adopt corresponding Warning Mark to different fire escape shapes, as signs such as " one " font, " ten " font, arrow points.
Smoke Sensor is used for sending fire alarm to singlechip controller when breaking out of fire.
Be connected to the broadcast sounds prompt system from singlechip controller, fire alarm is reported to the police.
Whole device is by storage battery power supply, and battery is connected the fire-fighting AC power, and when the generation fire alarm can not be switched on, battery provided the electric weight supply of whole device.
The working method of described singlechip controller is divided into passive startup and initiatively startup, and described passive startup refers to start work automatically by Smoke Sensor or building power supply cut-out etc., and described active startup refers to by the fire control system startup of networking or manually starts.Two kinds of working methods have guaranteed the functional reliability of device.
