针对传统的有线测试方法安装麻烦、线路复杂、受干扰较多等缺点,会造成信号噪声过大、信号失真,甚至会出现采集到的信号无效的问题,提出了一种基于复合量程加速度计的无线传感器网络,并对其进行了性能测试。测试结果表明:设计的无线传感器网络可以无损耗地传输复合量程加速度计输出信号,完成对覆盖区域加速度信号的测量。
Aiming at problems of many disadvantages of traditional wire test, for example, hard to install, the wire is too complex, and there are many interferers,which will cause the large noise and distortion of signal, sometimes even cause invalidation of collected signals, a wireless sensor networks (WSNs) based on multi-ranged aceelerometer is proposed and its capabilities are tested. Test results show that the designed WSNs can transmit output signal of multi-ranged accelerometer without loss, thus achieve measurement of acceleration signal in covering region.
