煤矿安全监控分站远程升级方案

针对煤矿井下安全监控分站升级和维护难的问题,提出了一种基于LPC2114处理器的煤矿安全监控分站远程升级方案;阐述了IAP技术原理,介绍了远程升级方案的思路、实现方法以及设计时应注意的关键问题。该方案一方面可保障升级数据包的正确传送,另一方面可保证在升级中断时自动运行升级前的程序,从而保证了升级过程的安全性。大量测试表明,在低速率条件下,该方案可安全稳定地实现煤矿安全监控分站的远程升级。

Remote Upgrade Resolution of Safety Monitoring and Control Sub-station of Coal Mine

In allusion to difficulties of upgrade and maintenance of safety monitoring and control sub-station of coal mine underground,the paper proposed a remote upgrade solution of safety monitoring and control sub-station of coal mine based on processor IPC2114,described technical principle of IAP,and introduced idea and implementation of the solution as well as several key issues which should be paid attention to when designing the solution.The solution can ensure correct transmission of upgrade packet on one hand,and on the other hand it can ensure the sub-station running the unupgraded program automatically when the upgrade process is interrupted,so as to ensure safety of upgrade process.A large number of tests showed that the solution can realize remote upgrading of safety monitoring and control sub-station of coal mine safely and stably at low speed.
