摘要
为提升农作物植保作业中无人机的电源容量、续航能力和通信效果,以STC8A8K64S4A12处理器为平台,集成数据采集模块(CS5460A)和通信模块(RS485),利用单片机C语言和汇编语言指令,设计了一种基于嵌入式微处理器为核心的农用无人机电流表系统,并使用多功能校准仪、信号发生器、示波器等仪器就输入数据和显示数据的稳定性和可靠性进行试验验证,并对引起测量误差的起因进行了研究分析。通过无人机飞行实验,验证了此电流表系统的稳定性和可靠性,解决了无人机电源容量校小、续航能力差和通信效果不佳等问题。
In order to improve the power capacity,endurance and communication effect of UAV in crop plant protection,a kind of ammeter system for agricultural UAV Based on embedded microprocessor is designed with stc8 a8 k64 s4 a12 processor as the platform,integrating data acquisition module(CS5460 A) and communication module(RS485),using MCU C language and assembly language instruction The stability and reliability of input data and display data are tested by signal generator,oscilloscope and other instruments,and the possible measurement errors are analyzed.Through the UAV flight test,the stability and reliability of the meter system are proved,and the problems such as small power supply capacity,poor endurance and poor communication effect are solved.
