摘要
在已有生物电研究的基础上,设计了一种非接触式电鳗放电电压实时监测系统。数据采集端利用电容充放电原理收集电荷,并将所收集电荷通过换算转换成相应的电压。利用JN5139无线模块发送和接收数据,避免了采集端和接收端电源共地串扰问题。该系统可实时监测、显示电鳗放电电压。现场测试结果表明,非接触式方法在测量生物电过程中具有良好的稳定性和可靠性。
On the basis of the study of biological electricity, a voltage real-time monitoring system of non-contact electric eel discharging is designed. The data acquisition terminal collects charges according to the capacitor charging and discharging principle, and transfers the collected charges to the corresponding voltage through conversion. JN5139 wireless module is adopted to deliver and receive data, thus the crosstalk problem of power between acquisition terminal and receiving terminal is avoided. The system can monitor and display the electric eel discharging voltage in real time. Field tests show that non-contact method features good stability and reliability in the measurement of bioelectricity.
