Temperature and Humidity Monitoring System Based on SOPC and Embedded Ethernet

In order to realize the real-time remote monitoring of temperature and humidity data,this paper puts forward the design scheme of a temperature and humidity monitoring system based on the SOPC and embedded Ethernet interface. The system makes full use of the rich resources of the SOPC system. The hardware architecture of the building has Nios II soft core CPU and the peripheral IP as the core in the software of Quartus Qsys. By porting theμ C /OS Ⅱ operating system as a software platform,using Lw IP as the network communication protocol,and combining LAN91C111 with FPGA to constitute an embedded Ethernet interface,the temperature and humidity data is transmitted and controlled. Due to its flexible design,extendibility,resource-effectiveness,and cost-effectiveness,the circuit structure is greatly simplified,making the design simple and easy to implement.
