Jian Yu Wang, Shao Zhong Li · Advanced materials research · 2012
The remote upgrade intelligent instrument is designed using in system programming technology, embedded microcontroller and net work technology. Upgrade hardware platform of intelligent instrument is constructed withW78E516 single chip computer, in system electricity programming analogue circuit EPAC and digital circuit EPDC. Remote hardware function reconstructing and the system upgrade principle of intelligent instrument are described in detail. Hardware and software design methods are stressed; the reliability and keeping secret of system remote upgrade are discussed. The testing of hardware and software has been done and the experiment results show that system has the advantages of stable performance and flexible operation, and it could realize remote auto upgrade.
