摘　　要：为便于新疆棉田残膜回收的精准作业收费和补贴,设计了一种残膜回收机有效作业面积监测系统。通过仿真试验对比锁相放大器降噪前后残膜回收机作业时经纬度数据,得出锁相滤波对于噪声环境有较好的抗干扰性能;采用高斯投影正算方法将降噪后经纬度数据转化为平面坐标,得出1.5°带的高斯投影的相对误差相较于3°带降低了0.01%。同时,利用卡尔曼滤波算法和构成角方法筛选有效作业轨迹,使用缓冲区法计算重复作业面积,最终利用轨迹算法精准获取残膜回收机有效作业面积,得出所设计的残膜回收机有效作业面积监测系统对于大块农田测量时相对误差为2.6%,对于小块农田测量时相对误差为3.3%。研究结果表明:所设计的残膜回收机有效作业面积监测系统可以精确计算出残膜回收机的有效作业面积,为残膜回收机作业质量评估提供了一定的理论基础。In order to facilitate the accurate operation charge and subsidy of residual film recovery in Xinjiang cotton field,this study designed an effective operation area monitoring system for residual film recovery machine.Through the simulation test,the latitude and longitude data of the residual film recycling machine before and after the noise reduction of the lock-in amplifier are compared,and it is concluded that the lock-in filter has better anti-interference performance for the noise environment.Then,the Gauss projection forward calculation method is used to transform the latitude and longitude data into plane coordinates after noise reduction.It is concluded that the relative error of Gauss projection in 1.5°band is 0.01% lower than that in 3°band.At the same time,the Kalman filter algorithm and the composition angle method are used to screen the effective operation trajectory,and the buffer method is used to calculate the repeated operation area.Finally,the trajectory algorithm is used to accurately obtain the effective operation area of the residual film recycling machine.It is concluded that the effective operation area monitoring system of the residual film recycling machine designed in this study has a relative error of 2.6% for large farmland measurement and 3.3% for small farmland measurement.The results show that the effective working area monitoring system of residual film recycling machine designed in this study can accurately calculate the effective working area of residual film recycling machine,which provides a theoretical basis for the quality evaluation of residual film recycling machine.
