摘　　要：为了适应气象现代化、智能化的发展趋势,解决系统结构复杂、布线繁琐等问题,提出了一种基于AM335X的智能采集器模块设计方法,实现对传感器信号的高精度采集与处理。系统依托Ubuntu嵌入式软件开发平台;硬件部分利用模块化结构设计,将相似的部分划在一起,尽量避免模块间的相互衔接,增强了体系的可靠性,同时提升了设计的层次化标准。软件部分基于SecureCRT测试环境,搭建函数动态链接库,采用多线程通信结构,使得软件结构简单,易于实现。测试结果表明:该模块能有效地实现对数据的采集处理,符合应用要求。In order to adapt to the meteorological modernization,intelligent development trend,to solve the complex system structure,wiring cumbersome and other issues,a design method of intelligent acquisition module based on AM335X is proposed,which can realize the high quality acquisition and signal processing of the sensor. The system relies on Ubuntu embedded software development platform. The hardware part uses the modular structure design,it divides the similar parts together,as far as possible to avoid the interaction between modules,enhance the reliability of the system,and enhance the design of the hierarchy standard. The software part is based on SecureCRT test environment to set up the function of dynamic link library. By using the multi thread communication structure,making the software structure is simple and easy to implement. The test results show that the module can effectively achieve the data acquisition and processing,in line with the application requirements.
