摘　　要：针对目前犁体外载的测定装置在数据采集方面普遍地使用磁带记录,导致在测量精度、数据处理、数据分析、动载测定等方面都存在较大问题的情况,利用AT89S8252单片机为核心设计了犁体外载数据采集系统的硬件电路和软件流程。与犁体外载六分力仪配套使用的性能检测与应用试验表明,该数据采集系统能有效进行犁体外载的实时测量,性能稳定,工作可靠,消除了以往磁带记录的各种弊端,有效降低了劳动强度,为犁体的动力学研究提供了必要的原始数据。At present,data collection devices of plow load generally use tape record, which exist many problems in precision measurement, data processing, data analysis, dynamic load measurement. This paper used AT89S8252 as core to design the plow in load data collection system which included the hardware circuit diagram and software flowchart. The result shows that the system can measure plow load efficiently, while it worked with the six-component device of plow load. It could eliminate the previous disadvantages of tape record, effectively reduced the labor intensity, and provided the necessary raw data. It has important meaning for improving the design of plow.
