柑橘大实蝇成虫数量检测及激光灭杀系统

为减少化学农药的使用,降低种植成本,解决化学农药灭杀和农药残留所引起的二次污染,有效防治柑橘大实蝇(Bactrocera minax)虫害,采用单片机STC89C52为控制核心,运用红外检测和激光灭杀技术,基于特定的检测计数算法,研制了能自动检测和灭杀柑橘实蝇成虫的太阳能激光灭杀系统.同时,构建了样机对设计原理进行验证,验证结果表明,实蝇成虫数目实际值与系统检测值之间较接近,最小误差3.5%,最大误差8.6%,实蝇成虫进入时能及时开启激光器照射和灭杀.

The development of number detection and laser destroying system for killing Bactrocera minax

In order to remediate the inset pest caused by Bactrocera minax in citrus planting industry, cut off the use of chemical pesticide and planting cost, meanwhile to solve secondary pollution arose from pesticide and pesticide residue. The Bactrocera minax laser killing system with microcontroller STC89C52 as a control core, powered by solar energy, using infrared detection and laser killing technology were pre- pared, which Bactrocera minax could be detected and killed automatically. The structure of the prototype was constructed to verify the principle. Experimental data showed that the counting value and real value were approximate, minimum relative error was 3.5% , and the maximum error was 8.6%. The laser emitter could be activated immediately while incoming pest was detected.
