摘　　要：现有的电力物联网内外信息交互系统的交互性能较低、信息交互过程耗时较长且输出结果信噪比较低。为了解决上述问题,文中设计了双网隔离环境下电力物联网内外信息交互系统。系统硬件部分由FPGA开发板、TFT-LCD显示屏、AD8011运放芯片组成;软件部分采用Java语言完成程序与内外网服务交互组件的设计。实验在特定环境下完成性能测试,结果表明,所提系统应用服务器的内存利用率和CPU使用率在50%以下,能够承受用户大规模访问的压力,且信息交互过程用时短、效率高,信息输出结果信噪比较高,说明所提电力物联网内外信息交互系统性能更优。The existing power Internet of things internal and external information interaction system has low interaction performance,long information interaction process and low output signal and noise.In order to solve the above problems,an internal and external information interaction system of power Internet of things is proposed in a double-network isolation environment.The hardware part of the system is composed of FPGA development board,TFT-LCD display screen and AD8011 operational amplifier chip.The software part uses the Java language to complete the program and the inner and outer network service interaction component design.The experiment completed performance tests in a specific environment,the results show that the proposed system application server memory utilization and CPU utilization rate below 50%,able to bear the pressure of mass access to users,and information interaction process short,high efficiency,information output high signal noise ratio(SNR),shows that the proposed power of things inside and outside information interaction system is of better performance.
