【摘要】：当今,卫星导航系统已成为世界各主要国家综合国力及科学技术发展水平的重要标志之一,是国防和经济发展的重要组成部分。北斗卫星导航定位系统是我国独立自主研发、建设的卫星导航定位系统,是国家安全战略的需要,是社会经济发展的需要,是我国改革开放30年科技进步的一项标志性成果,它的出现打破了美、俄的垄断地位,使我国成为第三个拥有自主卫星导航系统的国家,体现了我国的综合国力,具有划时代的意义。2006年,北斗系统与美国GPS、俄罗斯GLONASS和欧盟伽利略系统一起被联合国卫星导航委员会正式确认为四个全球卫星导航系统核心供应商。北斗卫星导航系统主要功能包括定位、通信、授时,并具有导航等其它功能。中国北斗卫星系统是继美国GPS、俄罗斯格洛纳斯、欧洲伽利略之后,全球第四大卫星导航系统。北斗卫星导航系统2012年将覆盖亚太区域,2020年将形成由30多颗卫星组网具有覆盖全球的能力。高精度的北斗卫星导航系统实现自主创新,既具备GPS和伽利略系统的功能,又具备短报文通信功能。国家电力部门对于利用北斗技术远程采集数据十分有兴趣,已做过多次的前期调研。该技术的市场前景良好。由于北斗I型通讯机首先具有双向数字报文通信能力能进行方便的指挥和信息互通;其次可进行点对点、一点对多点的信息传输,便于调度与控制,为运营平台提供了极大的便利;还能实现实时传输,各项指令通过卫星传输,不受地域和空间限制,可以随时机动通信,为处理突发事件赢得宝贵时间。因此特别适用于偏远地区的数据传输,对于广大人烟稀少的山区、牧区,既无光纤通路,也无移动或联通等公网信号,常用的通信通道在这种地区在则显得无能为力,而新铺设光缆也存在成本过高、通信架构受限等诸多问题。为此我国电力部门选定青海省的某一台区作为远程抄表试点项目。其核心任务是利用北斗卫星的短报文远程传输技术研制一个安装简单的嵌入式装置来代替传统的GPRS通讯来传输每个台区的电量数据表的数据,以实现偏远地区的数据传输任务。本课题即是围绕着这一项目展开,创造性地将北斗传输协议与国网传输协议相结合,实现远程电量数据与国网信息平台的数据透传,是我国首例解决远程电力抄表的案例实现,在青海省电力系统中应用效果良好。
[Abstract]:Nowadays, the satellite navigation system has become one of the important symbols of the comprehensive national strength and the level of scientific and technological development of the major countries in the world, and is an important component of national defense and economic development. Beidou satellite navigation and positioning system is a satellite navigation and positioning system independently developed and built in China. It is the need of the national security strategy, the need of social and economic development, and the landmark achievement of scientific and technological progress over the past 30 years of reform and opening up in China. Its emergence has broken the monopoly position of the United States and Russia, making China the third country to have its own satellite navigation system, which reflects the comprehensive national strength of our country and has epoch-making significance. In 2006, Together with US GPS, Russian GLONASS and the European Union Galileo system, Beidou was officially recognized by the United Nations Satellite Navigation Committee as the four core global satellite navigation system providers. The main functions of Beidou satellite navigation system include positioning, communication, timing, and other functions such as navigation. China Beidou Satellite system is the fourth largest satellite navigation system in the world after US GPS, Russian Glonus and European Galileo. The Beidou satellite navigation system will cover the Asia-Pacific region in 2012 and will form a global network of more than 30 satellites by 2020. Beidou satellite navigation system with high precision realizes independent innovation, which not only has the functions of GPS and Galileo system, but also has the function of short message communication. The national electric power department is very interested in using Beidou technology to collect data remotely. The market prospect of the technology is good. Because Beidou I communication machine has the capability of two-way digital message communication, it can carry out convenient command and information exchange, and then it can transmit information from point to point, one point to many points, which is convenient for dispatch and control. It provides great convenience for the operation platform, and can realize real-time transmission. The instructions are transmitted by satellite, and can be mobile communication at any time, which can save valuable time for dealing with unexpected events. Therefore, it is especially suitable for data transmission in remote areas. For the vast mountainous areas and pastoral areas, there is neither optical fiber access, nor public network signals such as mobile or connected, and the commonly used communication channels in such areas appear powerless. However, the new fiber optic cable also has many problems, such as high cost and limited communication structure. For this reason, the electric power department of our country selected a certain area of Qinghai Province as the pilot project of remote meter reading. Its core task is to develop a simple embedded device to transmit the data of the electric data table in each station area instead of the traditional GPRS communication by using the short message remote transmission technology of Beidou satellite to realize the data transmission task in the remote area. This topic is around this project, creatively combine Beidou transmission protocol with national network transmission protocol, realize remote electric quantity data and data transmission of national network information platform, it is the first case of solving remote electric power meter reading in our country. It has been applied well in Qinghai electric power system.
