摘  要：
为实现无土栽培基质参数的快速准确测量,基于自制的基质多参数复合传感器,并结合Zig Bee无线网络技术,研制了便携式基质多参数无线检测仪。检测仪采用分体式设计,由无线复合传感器和手持终端两部分组成。无线复合传感器采集基质参数信息,并以无线的方式将信息发送到手持终端;手持终端对接收到的测量参数信息进行处理分析、显示、存储和查询等。检测仪性能试验表明,含水率测量误差为-0.4%~3.1%,相对误差为-3.2%~9.6%,且对不同基质具有较好的适应性;电导率测量误差为-0.015~0.179 m S/cm,相对误差为-4.7%~10%,且对不同基质具有较好的适应性;温度测量误差为-0.63~0.69℃,相对误差为-1.1%~3.3%。检测仪能够满足无土栽培基质参数检测的要求。

摘  要：
To measure the parameters of soilless substrates quickly and accurately,based on a self-made compound sensor for multi-parameter of soilless substrates,combined with Zig Bee wireless network technology, a portable wireless detector for multi-parameter of soilless substrates was designed.Considering the practicality and convenient operation,the principle of separated design was employed.The detector included a handheld terminal and a wireless compound sensor. The wireless compound sensor,including a self-made compound sensor and a CC2430 wireless module,collected data of water content,electrical conductivity and temperature in soilless substrates,and sent the data to the handheld terminal by wireless. Then,the handheld terminal received the data through another CC2430 wireless module,and progressed with a MSP430F5438 A single chip. The measure results can be displayed,recorded,queried and deleted with the help of a 12864 LCD displayer and a keyboard. The tests demonstrated that error range of water content measurement was-0. 4% ~ 3. 1%,and relative error range was-3. 2% ~ 9. 6%; error range of electrical conductivity measurement was-0. 015 ~0. 179 m S / cm,relative error range was-4. 7% ~ 10%; the error range of temperature measurement was-0. 63 ~ 0. 69℃,the relative error range was-1. 1% ~ 3. 3%. The measurement error of detector was small enough to match the detection precision of agricultural production,and the detector was suitable for different substrates.
