Linux下抄表前置通讯机的软件设计

The Design of a Linux-based Front-end Machine Software

在电力公司远程抄表系统中,前置通讯机处于关键地位。通过OOP编程思想,利用多任务机制,在Linux下实现了Modem池的操作、网络TCP通讯以及网络数据库的访问,完成了前置通讯机的软件设计。经实际运行,该前置通讯机运行稳定、可靠。

The front-end machine plays an important role in the system of remote meter data accessing. In this paper, the designing o（ a Linux-based （ront-end machine so（tware is given using the OOP method and multi-task programming, which includes the operating with modem pool, the communication under TCP protocol and accessing to network database. The result of practical testing shows that the front-end machine software is stable and reliable.
