Abstract
Aiming at the inaccessible problem of remote embedded devices update and maintenance , this paper presents a method using general packet radio service (GPRS) to achieve update based on the embedded real-time operating system (RTOS)μC/OS-Ⅱ .It introduces architecture of the system first .And then it uses LPC1768 chip as the central processing unit ,SIM900A module for data transmission ,and SST25VF016B to store the data .To ensure accuracy of the data transmis-sion ,cyclic redundancy code (CRC) is adopted .The software uses fixed bootstrap and mutable update program ,and thus the embedded devices can still normally start in case of update failure .Finally ,high stability and extensive adaptability of the system are verified by experimental data .关键词
