果园自动对靶喷雾机红外探测控制系统的研制

Research and development of infrared detection system for automatic target sprayer used in orchard

针对目前果园自动对靶喷雾机红外探测控制系统易受环境影响、工作不稳定、探测距离近的缺陷，研制了一种由集成电路构成的果园自动对靶喷雾机红外探测系统。结果表明：系统的探测距离为0～6．15m，最小识别间距小于0．3m；系统工作稳定、灵敏度高、体积小、不受自然光的干扰。

The operation of infrared detecting system for automatic interference resulted from crucial designed defects, including short target orchard sprayer was hard to work well in rough environment detectable distance, complex circuit, and high cost of the automatic target detector. An infrared detecting system consisting of integrated circuit for orchard automatic target sprayer was developed. Test results showed that this system satisfied in detail the design requirements of stability, sensibility, compact volume and anti-interference from environmental ray, and the detectable distance between the detector and the targets was variable from 0 to 6.15 meters, and the space between two spraying targets was no more than 0.3 meter.
