根据田间杂草智能喷施系统中图像处理计算量大、实时性要求高、控制任务重的特点,提出了一种基于DSP和单片机相结合的双CPU系统方案,充分利用了DSP实时数据处理能力强和单片机外围控制能力强的优点,实现了系统的快速运算和实时控制功能。同时,介绍了系统的设计方案以及DSP、单片机各自功能的软件实现。试验表明,系统在室内条件下可以满足实时对靶喷施除草的要求。
According to the characteristics of the field weed intelligent spraying system, such as large amount of image processing, high real-time requirements and heavy control tasks, a dual CPU system based on DSP and single chip microcomputer is proposed, which makes full use of DSP real-time data processing capability Strong and SCM peripheral control advantages of strong, to achieve the system’s fast computing and real-time control functions. At the same time, the design of the system and the software of each function of DSP and SCM are introduced. Experiments show that the system can meet the requirements of real-time target spraying weed control under indoor conditions.
