摘要
光照强度是环境监测中的重要参数,它对种子培育、动植物生长、药品的物理性能和化学性能有着重要的影响,研制光照试验系统具有较大理论和现实意义。传统的光照强度调节模式常采用晶闸管调节导通角来调节白炽灯光照强度和采用多个节能灯分段调节的方式,上述方式存在不节能或者光照强度调节不连续的弊端。本文提出了基于物联网技术的在线监测光照强度进行闭环控制模拟整流器调节光照强度,试验表明该系统可解决传统光照设备不能同时克服的节能与连续调节的问题。该系统完全可满足光照试验系统的要求,具有一定的推广价值和应用前景。
Intensity of illumination is an important parameter in environmental monitoring which strongly affect the cultivation of seeds, the growth of animals and plants, the physical and chemical properties of the drug. The research on illumination testing system has both theoretical and practical significance. Through the use of thyristor in adjusting turn-on angle, the traditional light intensity adjusting mode regulate the light intensity of incandescent lamp and implement the mode of the adjustment of several energy-saving lamps. But this still exist some disadvantage in the failure of energy saving and discontinuous of illumination adjustment. This paper proposed the using of the intemet of Thing and controlled the ballast adjust light intensity. The experiment indicates this new system can solve the problem of the failure of energy saving and discontinuous adjustment which exist in traditional lighting devices. This system can fully satisfy the requirement of light testing system which has both market value and practical prosperous.
