%X 在农田基本建设和农机作业中，作业面积是一个关键数据，在农机作业时尤为重要。为实时测量农田作业面积，提高测量效率和面积计算精度，设计了一种基于北斗的农田作业面积测量装置，并提出了一套根据作业区域形状而定的面积计算方法。装置以AT89S52作为主控制器，采用北斗接收模块UM220-Ⅲ作为定位模块，此外还包括按键，液晶显示屏，RS-232电缆等外围器件。使用者手持测量装置进行实时测量时，可根据不同情况选择相应的算法计算面积。在计算不规则作业面积时，提出了一种运算速度较快的面积计算方法，该方法可识别测量过程中产生的粗大误差，简化运算，减少程序冗杂。通过对测量装置进行的实验测试和分析，该装置能够测量任意形状农田的面积，相对测量误差在8%以内，并且测量面积愈大，测量的相对精度愈高。该装置可广泛运用于精细农业，很大程度上提高了测量农田作业面积的便利性。<br />
In farmland infrastructure and agricultural machinery operations, the operating area is a key figure, especially important in agricultural machinery operations. In order to measure farmland operation area in real time, improve measurement efficiency and area calculation accuracy, a Beidou-based farmland area measurement device was designed, and a set of calculation method based on the shape of the work area was proposed. The device adopts AT89S52 as the main controller, adopts Beidou acceptance module UM220-III as the positioning module, and also includes peripheral devices such as buttons, liquid crystal display and RS-232 cable. When the user holds the measuring device for real-time measurement, the corresponding algorithm can be selected ac-cording to different situations to calculate the area. When calculating the irregular working area, an area calculation method with high precision and fast calculation speed is proposed. This method can identify the coarse error generated in the measurement process and improve the calculation accuracy. Through the experimental test and analysis of the measuring device, the device can measure the area of any shape farmland, the relative measurement error is less than 8%, and the larger the measurement area, the higher the relative accuracy of the measurement. The device can be widely used in fine agriculture, which greatly improves the convenience of measuring the working area of farmland.
