For the requirements that distributed photovoltaic power generation system needs real-time monitoring in run-time,a real-time monitoring system based on CAN bus and the embedded Web server was designed.An embedded Web server based on the S3C2440 with DM9000A and a data acquisition system based on TMS320F28335 were designed.GoAhead server technology, B/S structure and AJAX technology were used and corresponding CGI programs were given.The browser concentrately dis-played device’s status,and the remote monitoring was realized.Experimental results show that this system is stable,highly real-time,and has good openness,portability and broad application prospects.%针对分布式光伏发电系统运行时需要实时监控的要求，设计基于CAN总线和嵌入式Web服务器的实时监控系统。设计以 S3C2440和DM9000A为核心的嵌入式 Web服务器，以 TMS320F28335为核心的数据采集系统；采用 GoAhead 服务器、B/S结构和 AJAX技术，给出相应的CGI程序；通过浏览器集中显示设备状态，实现远程监控。实验结果表明，该监控系统运行稳定，实时性高，能够远程实时监控，具有良好的开放性、可移植性和广阔的应用前景。
