Research and implementation on determination method of soil permeability coefficient based on the wireless sensor network

为实现远程准确测定土体渗透系数,研制出测定可变土体试样渗透系数的无线土体渗透系数测量装置。该装置以STM32F103芯片为核心完成ADC采样,采用CC2530模块实现透明传输,通过数据采集处理程序进行滤波。大量实验证明,采用该装置进行土体渗透系数的方法稳定可靠,具有较高的实时性和准确性。

It was designed in order to realize the remote and accurate measurement of the soil permeability coefficient. The equipment took the chip STM32F103 as the core to accomplish ADC sampling, used the model CC2530 to realize transparent transmission and adopted the data collecting and processing program to do the smoothing. A large number of experiments prove that the method is stable and responsible, and has higher real-time per- formance and accuracy.
