摘要: 为满足喷杆喷雾机变量喷雾技术需要,设计一种喷杆喷雾机变量喷雾控制与测试试验台,实现对已有的变量喷雾装置的实时控制以及性能测试。变量喷雾控制与测试试验台由控制系统和数据采集系统组成。控制系统以西门子S7-200 系列PLC为基础,由动力系统、驱动系统、流量系统和变量控制系统组成;数据采集系统采用数据采集模块与传感器获取管路流量、压力、转矩和行驶速度等参数,通过LabVIEW软件对采集的参数进行实时显示和存储。转速工况下的流量精度测试试验显示平均流量误差为4.0%,可作为判定变量喷雾装置性能的一个技术参考;试验表明该试验台可有效实时控制喷杆喷雾机变量喷雾控制部件,满足喷杆喷雾机变量喷雾控制部件的性能测试需求,为制定变量喷雾质量评价技术规范提供技术参考。

Abstract: In order to meet the needs of variable spray technology for boom sprayers, a variable spray control and test bench for boom sprayers were designed to realize real-time control and performance testing of existing variable spray devices. The variable spray control and test bench are composed of a control system and a data acquisition system. The control system is based on Siemens S7-200 series PLC, which is composed of a power system, drive system, flow system, and variable control system. The data acquisition system uses data acquisition modules and sensors to obtain pipeline flow, pressure, torque, driving speed and other parameters. Real-time display and storage of the collected parameters can be achieved through LabVIEW software. The flow accuracy test under the speed condition shows that the average flow error is 4.0%, which can be used as a technical reference for judging the performance of the variable spray device. The test shows that the test bench can effectively control the variable spray control components of the boom sprayer in real-time to meet the requirements of the boom sprayer. The performance test requirements of variable spray control components of sprayers provide technical reference for the formulation of technical specifications for variable spray quality evaluation.
