岩石的组成结构各不相同，导致其具有极大的复杂性，同时钻探过程具有多变性。因为我们在钻探过程中会受到众多因素的影响，所以，钻探生产便成为一个较为复杂的工艺过程。对于这样一个过程，我们为了达到使生产安全、优质、高效、低耗等目标，不仅要对工艺进行优化，而且还要对钻探过程中各参数信息的实时情况进行分析，并根据参数变化及时有效地对钻探工艺进行调节，在此过程中，钻进数据的实时采集与数据传输是钻探过程监测与监控的关键技术之一。 针对煤矿井下钻探作业过程中现有数据的有线传输所存在的不足，本文对基于声波的钻进参数无线传输系统进行深入研究。在对声波传输原理、钻杆结构特点，以及声波在钢管中的传播特性等进行分析的基础上，建立了数据传输的纵波传播模型；确定了适宜于传输信号的载波类型；针对钻杆信道和井下数据的特点，采用二进制频移键控调制技术与差错控制正反码编码技术，对随钻数据传输信息进行处理；完成了钻进参数声波无线传输系统的架构；设计了由声波发射模块、声波接收模块和电源模块，通信模块组成的无线传输系统，其中主要设计了声波发射模块和声波接收模块，声波发射模块主要包括超声波换能器，多谐振荡电路，功率放大电路，变压器；声波接收模块主要包括前置放大电路，带通放大电路，末级放大电路；在Multisim软件环境下对所设计的模块进行了仿真；通过实验环境下的物理试验，并结合Labview软件分析，验证了梳状滤波器合理性。

The variety of rocks’ structure and inscape leads to their great complexity, at the same time, the drilling production is changing all the time. There are many factors which is influencing us in the progress of drilling production, so the drilling production will become a more and more complex process. In the progress of drilling, in order to make the production safer, with high-quality, high- efficiency and low-cost, we should not only optimize the technique and analyze the real-time information of every parameter which has been gathered in the production, but also tune up the technique timely and effectively according to the variety of parameters. In this process, the real-time acquisition and the data’s transmission of the drilling data is one of the key technologies in the progress of monitoring and control drilling. In view of the disadvantage of wire transmission, existing in the drilling of underground workplace in the coal mine. We carry through the in-depth research of wireless transmission system based on penetrable parameters of acoustic theory. Based on the transmission principle analysis of sound wave, the structural characteristics analysis of drill pipe and propagation property analysis of sound transmission in steel pipe, we build the data transfer propagation model of longitudinal wave. We determine the carrier wave which is suitable for the transmission signal. We adopt the 2FSK technology and an error control coding technology-positive and negative coding, keeping in mind the characteristics of drill pipe and the embedded coal mine data, in order to deal with the data which is attained in the progress of. We have structured the wireless transmission system of acoustic parameters in the well logging while drilling. We have designed the wireless transmission system which is including the acoustic transmitter module, the sound receiver module, power module and communication module. The most important modules are the transmitter and receiver module. The acoustic transmitter module mainly includes ultrasonic transducer, multivibrator circuit, power amplifier and transformer. The sound receiver module mainly consists of preamplifier circuit, band-pass amplifier circuit and the final amplifier circuit. At last, we simulate the designed modules in the Multisim software environment. Through the physical experiment in the laboratory and the Labview software analysis, the rationality of comb filter is validated.
