基于RS-485的智能消防炮远程更新方法设计

为解决智能消防炮控制系统程序更新困难和维护繁琐的问题, 提出一种基于工业总线网络接口RS-485的智能消防炮远程更新方法。首先设计一套基于现有智能消防炮的总线网络通信接口的微控制器起始驻留程序和消防炮控制主机软件, 然后通过专用的烧录工具将起始驻留程序烧写进微控制器, 当需要更新应用程序时, 只须利用网络接口即可实现对其更新升级。应用测试结果表明, 该方法效率高, 成本低, 危险性小。  

The Design of Remote Updated Method Based on RS-485 for the Intelligent Fire Cannon

In order to overcome the difficulties of updating intelligent fire cannon, an update-system for intelligent fire cannon is designed based on industrial bus network interface RS-485.We designed a set of resident program and monitor control software based on the existing bus network interface.The resident program was downloaded to the microcontorller and the controller program can be updated through the interface.The test results show that the method is of high efficiency, low cost and little risk.
