井上泥浆压力脉冲信号的无线高速采集与传输系统∗

摘要

In order to receive and demodulate the mud pulse signals of rotary steerable tool in downhole, We developed a compound mud pressure acquisition and transmission system. The system is not only compatible with voltage type and current type pressure sensors, but al-so compatible with wireless and wired data transmission mode.%为了实现接收与解调井下旋转导向工具上行传输的泥浆脉冲信号，设计了一种复合型泥浆压力采集与传输系统。该系统具备高精度、高速率、抗干扰及高可靠的信号采集性能，不仅兼容电压型和电流型压力传感器两种采集模式，同时也兼容无线型和有线型两种数据传输模式。
