资料介绍

为了得到准确的测量数据和较高的同步精度,设计一种能同步检测四通道的地震槽波信号的电路方案,对电源管理模块和信号调理单元设计方案进行了改进。电源管理模块使用低压差线性稳压电源,大大提高了电源的精度和稳定性,最大限度地抑制了电源本身的噪声,同时实现低功耗。在信号调理单元的设计中,选择低通滤波和程控放大器电路组合,提高对槽波信号的检测精度和电路抗干扰能力。结果表明设计的分布式槽波地震仪模拟电路系统稳定,具有较高的同步和信号检测精度,满足实际应用要求。

To obtain accurate measurement and high accuracy of synchronization,we designed a circuit that can synchronously detect four-channel signals from in-seam seismograph,in which the power module and signal processing unit were improved.We used a low-dropout linear regulator for the power management module,which significantly improved the accuracy and stability of the power supply and minimized the noise with low power consumption.In the signal conditioning unit,the low-pass filtering was combined with programmable amplifier circuits to improve the detection ability of the slot signal and the anti-jamming capability.The results show that the designed distributed slot wave seismograph analog circuit system is stable with high synchronization and signal detection accuracy,which meets the practical application requirements.
