摘要:

针对UV LED固化系统行业存在的调试、升级频繁导致的维护及人员成本突出的问题,提出了一种支持断点续传的UV LED固化系统远程升级方法；利用基于STM32系统的IAP技术配合改良的远程升级程序代替传统J-LINK的调试烧写,节约了调试人员奔赴现场调试的时间和成本；由于远程传输必然有一定的误码率,而利用断点续传技术可以大幅缩减使用GPRS等作为远程传输模块时的流量消耗；考虑到固化系统的安全性,提出利用分包计算CRC和设置备用程序存储区域的方法加强了升级系统的可靠性；实验结果验证了该方法应用于UV LED固化系统远程调试升级的可行性及安全性,并且可以大幅缩减远程通信的流量,这在一定程度上提高了升级系统的安全性。

Abstract:

UV LED curing system for the industry, there is troublesome issues, such as:commissioning, upgrade and maintenance and personnel costs frequently lead to propose a support resuming of UV LED curing system upgrade. The use of technology-based STM32 IAP system with improved remote upgrade program to replace traditional J-LINK debug programming, commissioning personnel rushed to save the time and cost of on-site commissioning. Because the remote transmission must have a certain error rate, significantly reduced the use of HTTP to use technology such as GPRS remote transmission module as traffic consumption; take into account the safety of the cured system, proposed the use of subcontractors and set an alternate program to calculate CRC store a regional approach to strengthen the reliability of the system upgrade. Experimental results show the method is applied to UV LED curing system for remote debugging upgrade the feasibility and safety, and that this method can significantly reduce the flow of telecommunications, and to some extent, improve the security upgrade of the system.
