摘　　要：针对智慧农业设备分布范围广、所处位置偏远引起的现场软件更新工作强度大、难度高的问题,提出一种用于智慧农业设备的多平台嵌入式程序远程更新系统设计方法。该方法利用智慧农业设备中主控芯片DSP的SCI引导加载程序更新原理、ARM的IAP更新程序原理及智慧农业设备组网运行的特点,使用智慧农业设备唯一设备识别码可以指定更新某一个组网设备,并且应用程序和更新程序并行运行,对于重要数据无感更新,且在更新成功后可人为选择合适时机启动使用最新程序,将由于程序更新带来的数据丢失影响降到最低。该方法省时、省力、稳定、效率高、操作简便,具有一定的通用性,可以推广应用于组网运行环境下的嵌入式程序远程更新,具有较高的工程应用价值。In view of the high intensity and difficulty due to wide distribution and remote location of smart agricultural equipment in on⁃site software updates,a design method of multi⁃platform embedded program remote update system for smart agricultural equipment is proposed.In this method,the SCI boot loader update principle of the main control chip DSP in smart agricultural equipment,the IAP update program principle of ARM,and the characteristics of smart agricultural equipment networking operation are used.By the unique device identification code of smart agricultural equipment,a specific networking device can be specified for update,and the application program and update program run in parallel.There is no sense for updating important data.After the update is successful,humans can choose the appropriate time to start the latest program to minimize the impact of data loss caused by program updates.The proposed method is time⁃saving,labor⁃saving,stable,efficient,easy to operate,and has a certain universality.It can be promoted and applied to remote updates of embedded programs in networked operating environments,and has high engineering application value.
