用户侧并网光伏电站在线监测系统之数据上传系统，
解决网络字节序转换、CRC校验、AES加密、中文UTF-8编码等技术，
采用多线程解决在主动发送信息的同时监听数据中心服务器其他指令。
采用开发环境vc++6.0 + mysql,实现用户SN、密码、电站信息、
设备信息等全部在数据库中配置，在光伏电站项目信息改变或变更项目，不用更改系统源码，直接在数据库中更改相关信息就行了。
User side and network monitoring system of photovoltaic power plant data upload system to solve the network byte order conversion, CRC checksum, AES encryption, Chinese UTF-8 encoding techniques, the use of multi-threading to solve the initiative to send information at the same time monitoring and data center servers other instructions. Use development environment vc++6.0+ mysql, implement user SN, password, power information, device information, and all in the database configuration information changes in the PV power plant project or change the project, do not change the system source code, directly change the information in the database on the line the.

网络的安全问题得到人们的日益重视。网络面临的威胁五花八门：内部窃密和破坏，截收，非法访问，破坏信息的完整性，冒充，破坏系统的可用性，重演，抵赖等。于是公钥基础设施（Public Key Infrastructure，PKI）应运而生。PKI是电子商务和其它信息系统的安全基础，用来建立不同实体间的"信任"关系。它的基础是加密技术，核心是证书服务。用户使用由证书授权认证中心（Certificate Authority，CA）签发的数字证书，结合加密技术，可以保证通信内
