油田数据信息的短波传输技术

在油田勘探、开发和建设过程中，为了解决生产现场的各种数据信息及时上报到上一级的指挥决策部门，笔者研究了适合于边远、荒漠油田的数据传输技术，提出了一种适合于恶劣工作环境、通信距离远、性能／价格比高的数据信息的短波传输技术，为油田现代化生产调度系统、油田自动化的建设提供了一种可靠的通信手段．而短波信道是常用信道中最复杂的信道，它是由电离层反射电波实现通信的．短波通信中，通信控制是关键设备．同时就短波基本问题、短波控制器原理、数传控制收发软件作比较详细的讨论，并就短波通信干扰问题作一定的讨论．

The Application of Short Wave Technique in the Transmission of Data Information in Oilfields

In the process of oilfield exploration,development and construction,various field data information must be transmitted to decision departments.For this reason,this paper puts forward a short wave data information transmission technique,which is suitable for the communication in bad conditions and at a long distance.Its quality of transimission data information is high and cost is low.The technique provides a reliable communication means for the modernization and automation of the oilfield production management and construction.Short wave channel is the most complicated of common channels.It realizes communication by ionization reflecting electromagnetic wave.Controller is a key device in short wave communication.This paper disscusses the basic problems in short wave communication,the principle of the controller,and the software for controlling of receiving and sending data.The important paramenters describing the systems properties are also given.Because the mixed error control technique is adopted in the system,its bit error rate is less than 10 -8 in receiving data.
