中文摘要：

为了解决光谱仪内部数据库及程序的固件更新的需求，提出了一种基于C8051F020单片机的远程固件升级方法，并完成系统的软硬件设计。该系统在光谱分析仪中，主要实现了光谱信号的采集分析，同时可以将数据通过网络进行数据的传输，因此利用其具有远程通信的特点，实现了利用网络进行远程在线更新系统固件的方式。实际应用证明该方式简便有效，系统运行稳定。

英文摘要：

In order to solve the needs of the spectrometer database program firmware update, a method of remote firmware upgrade based on C8051F020 microcontroller is proposed, and the design of the system’s hardware and software is completed. The system in the optical spectrum analyzer, is mainly for acquisition and analysis of spectrum signal, and transfers the data through the network. Therefore, use of remote communication features, the romote update way of the system firmware is realized through the network online. The practical application shows that the method is simple and effective, and the system runs stable.
