文章介绍了一种由单片机控制的网络通信和管理系统。该系统可与PC进行实时通信 ,并可对采集到的数据随时进行刷新存储。网络建设者可根据信道噪声情况选择适合的数据调制解调方式 ,在利用HFC网络传送数据时具有信道自动倒换功能。文中从硬件构成和软件编程两个方面对系统作了详细介绍。
The article introduces a kind of network communication and management system controlled by SCM. The system can communicate with the PC in real time, and the collected data can be refreshed and stored at any time. Network builders can select the appropriate data modulation and demodulation method according to the channel noise situation, and have the function of channel automatic switching when transmitting data by using the HFC network. The article made a detailed introduction to the system from two aspects of hardware composition and software programming.
