| Abstract: | CompactDAQ platform was introduced and applied in the research.It was used to monitor the main parameters such as drying chamber inlet and outlet temperature,as well as relative humidity. Laptop(as the upper computer) was used in monitoring data real-time,displaying and storing synchronously.As the lower computer,CompactDAQ platform inserted with NI 9205 module transformed analog signal to digital one.The USB 2.0 bus was employed to transfer digital signal to the upper computer,meanwhile,the data was proces... |
