摘要
许多水产养殖基地仍然采用人工监管的方法,这种方式存在检测周期长、实时性差、效率低等缺点。为解决上述问题,基于ZigBee技术研发一个用于水质检测的无线传感网络系统。该套系统所涉及到的数据传输和无线传感网络的构建均通过协议栈的接口函数(API)实现,配合传感节点软件的使用来实现数据的采集与管理,实验采集的参数包括水的pH值、溶解氧值和电导率值。由于实地测试环境恶劣多变,故自主设计一套系统的PCB结构外观。通过3个月的实地测试,该套系统可以顺利采集各个参数数据,并进行传输和处理。通过对采集参数与实际值对比,传感器的相对误差绝对值较小,pH值、溶解氧值和电导率值的相对误差绝对值分别为0.49%、1.72%和0.23%。实验结果表明系统具有优良的合理性与准确性,设计科学,工作稳定。
Many aquaculture bases still adopt artificial monitoring methods, which have shortcomings such as long monitoring period, poor real-time performance and low efficiency. In order to solve such shortcomings, a wireless sensor network system for water quality monitoring system mainly depending on ZigBee technology has been developed. The data transmission and the wireless sensor network involved in the system are realized by the interface function（API） of the protocol stack, and the data acquisition and management in cooperation with the sensor node software are also realized. The parameters collected during test include water PH value, dissolved oxygen and conductivity values. As the field test environment is harsh and varied, a PCB structure appearance of system is independently designed. After 3 months of field testing, the system can successfully collect the various parameters and data, and transfer and handle them.The absolute value relative error of the sensor is relatively small, the absolute value relative error of p H value, dissolved oxygen and conductivity values is 0.49%, 1.72% and 0.23%, respectively,by comparing the collected parameters with the actual values. The test results show that the system has excellent rationality and accuracy with scientific design and stable performance.
