资料介绍

为了实时检测常温下的湿度,以便负责人根据需要调整环境状态。采用测频计数法结合频差法设计了以FPGA芯片(EP2CSQ208C8N)为基础的可用于湿度测量的石英晶体谐振频率漂移检测电路。重点介绍在FPGA平台上通过测量石英晶体的谐振频率来间接测量湿度的方法,讨论了FPGA平台上的每个模块的设计过程,给出了部分模块和整体电路的仿真图,解释了仿真结果。FPGA参与外围硬件电路的辅助设计,会使设计更加简单,周期更短。

For detecting the humidity values in real-time at room temperature, so that the person in charge adjusts the state of the environment. Quartz crystal resonators frequency drift detection circuit which is used for humidity designed as frequency counting method combining with frequency difference calculation method based on FPGA chip (EP2C8Q208C8N). The way of humidity measurement through indirectly measuring the resonant frequency of the quartz crystal on the FPGA platform was introduced emphatically, the design process for each module in the FPGA platform was discussed, the simulation diagram of some modules was given and the whole circuit, and the simulation results was explained. Combining with FPGA and peripheral hardware circuit,...
