【摘要】：森林火灾这个词语经常出现在我们的视野中,值得我们深思,应该怎样减少森林火灾的发生。既然做不到完全避免,就应该想办法有效的控制,有效的灭火。在南方山高坡陡,地形复杂,风向多变,昼夜温差不大的特殊条件下,无法进行夜间灭火,无法动用大兵团扑打复杂危险条件下的火场,扑救过程中容易发生危险,灭火时效性和安全性得不到保障,大部分人员伤亡来自于扑打火场过程中。进行科学扑救,严防重大人员伤亡事故的发生,牢固树立以人为本、安全第一的思想,保障人民群众生命安全已经成为扑救指挥工作的首要考虑问题。在历年森林火灾的扑救中,森林灭火弹一直担负着重要角色。本课题研究的是一种红外光电模块,装于弹头位置,其弹轴方向与探测器光轴方向平行,其功能是当弹丸距离火苗的距离为3至7米时给出控制信号,通知引线引爆炸药开仓,灭火粉抛撒向火堆已达到压制火势的目的。由于目前国内尚无此类红外光电模块,所以该研究课题其实是一种新的研究,它将使我国的灭火弹技术水平上到一个新台阶。该红外光电灭火弹敏感模块研究涉及到了使用热电堆型红外探测器高频放大电路设计、菲涅尔光学透镜、窄带滤光窗口设计。并通过实验来确定设计中的重要参数,并按照工艺制造出产品,参与了重庆长安工业集团有限公司的靶场实验,验证了该设计的可行性与实用性。由于该课题研究是我参与云南安防科技有限公司的灭火弹项目设计,应公司要求对部分设计进行保密。
[Abstract]:The term "forest fire" often appears in our field of vision, and it is worth pondering how to reduce the occurrence of forest fire. Since we can't avoid it completely, we should find ways to control and extinguish the fire effectively. Under the special conditions of steep slope, complicated terrain, changeable wind direction and small temperature difference between day and night, it is impossible to extinguish the fire at night, or to use a large regiment to fight the fire field under the complicated dangerous conditions, and it is easy to occur danger in the process of fighting the fire. Fire-fighting effectiveness and safety can not be guaranteed, most of the casualties come from the fire-fighting process. Carrying out scientific rescue, strictly preventing the occurrence of heavy casualty accidents, firmly establishing the idea of putting people first and safety first, ensuring the safety of the people's lives has become the first consideration in the rescue command work. In the past years of forest fire fighting, forest fire-extinguishing bomb has been playing an important role. This paper studies an infrared photoelectric module, which is installed in the warhead position. The direction of the projectile axis is parallel to the optical axis direction of the detector. Its function is to give the control signal when the distance from the projectile to the flame is 3 to 7 meters, and to notify the lead wire to detonate the explosive to open the silo. The fire extinguishing powder has been thrown into the fire to suppress the fire. Because there is no such infrared photoelectric module in our country at present, this research project is actually a new kind of research, which will bring the technical level of fire extinguishing projectile to a new level in our country. The research on the sensitive module of infrared photoelectricity fire-extinguishing bomb involves the design of high-frequency amplifier circuit using thermoelectric stack infrared detector, Fresnel optical lens and narrow band filter window design. The important parameters of the design are determined by experiments, and the products are manufactured according to the process. The experiment of the shooting range of Chongqing Changan Industrial Group Co., Ltd is carried out, which verifies the feasibility and practicability of the design. As this research is my participation in the fire extinguishing project design of Yunnan Security Science and Technology Co., Ltd., part of the design is kept secret at the request of the company.
