摘　　要：针对勘察数据传输方法存在的传输不稳定、可靠性差等问题,研究了基于无线通信技术的岩溶水文地质勘察数据传输方法。通过对地质勘察进行数据格式转换、建立勘察数据传输模型,实现数据传输。经实验分析,不同测试条件下,与基于预应力钢筒混凝土管(PCCP)、现场可编程门阵列(FPGA)的传输方法相比,本文方法的通信网络吞吐量更大,数据包接收率更高,证明本文方法是可靠的。Aiming at the problems of unstable transmission and poor reliability of survey data transmission methods,this paper studied the transmission method of karst hydrogeology survey data based on wireless communication technology.Through data format conversion of geological survey and establishment of survey data transmission model,data transmission was realized.Through experimental analysis,under different test conditions,compared with the transmission methods based on prestressed concrete cylinder pipe(PCCP)and field programmable gate array(FPGA),the communication network throughput of this method was higher and the packet reception rate is higher,which proved that this method was reliable.
