Description
一种北斗卫星全功能定位通信终端
技术领域
[0001] 本实用新型涉及一种北斗卫星全功能定位通信终端。
背景技术
[0002] 目前，GPS系统已经广泛应用到人民生活当中。但GPS卫星因为其工作原理的限制，只能单方面的获得位置信息。如果需要将位置信息进行传输，则必须借助于普通地面网络，比如GPRS网络等。但若遇到特殊环境，比如沙漠区、无人区、地震时，即普通地面网络不能覆盖到的盲区，则GPS位置就不能进行回传了，这对于一些监控系统来说是致命的缺陷。
实用新型内容
[0003] 本实用新型所要解决的技术问题是针对现有技术的不足提供一种北斗卫星全功能定位通信终端。利用北斗卫星定位系统的通信功能则可以比较好的解决上述问题。通过将北斗卫星、GPS卫星、GPRS网络、WIFI网络几者相结合，形成一个天地无缝的沟通网络。
[0004] 一种北斗卫星全功能定位通信终端，包括主控板、GSM网络芯片、串口转网口芯片、北斗定位芯片和显示控制器，所述GSM网络芯片、串口转网口芯片、北斗定位芯片和显示控制器均通过RS232与所述主控板连接；还包括基带处理板，所述基带处理板通过RS232与所述主控板连接，北斗通信接收天线通过低噪放和通道连接基带处理板；北斗/ GPS定位天线连接北斗定位芯片，WIFI天线连接串口转网口芯片，GSM天线连接GSM网络芯片。
[0005] 所述的北斗卫星全功能定位通信终端，还包括与GSM网络芯片连接的耳机和麦克风。
[0006] 北斗全功能定位通信终端是一款防水防尘等级达到IP67的北斗定位通信产品。产品集北斗卫星定位、GPS卫星定位、北斗卫星通信、GSM网络、GPRS通信系统、WIFI通信系统于一体。各定位系统、通信系统可完美完成无缝切换，具有强大的定位和通信功能，产品接收北斗导航卫星BI频点信号，GPS导航卫星LI频点信号，进行单系统定位或双系统融合定位，定位速度更快，精度更高。
[0007] 系统外接RS232串口和WIFI接口，可以通过这两者接口对产品进行控制。除此之夕卜，还可以通过两种接口接收外设数据。一方面在本地连接显示器，显示器中可显示定位数据和状态信息。另一方面，在有GPRS网络信号的情况下，系统的定位结果或外设数据通过GPRS网络发送给服务中心。若没有GPRS网络信号的情况下，系统的定位结果和外设数据可通过北斗导航卫星L/S频点进行发送给服务中心。
[0008] 产品位置除通过服务中心进行查询外，还可以通过手机短信的方式进行查看。
[0009] 产品还可以连接麦克风和耳机，完成打电话的功能。
[0010] 产品符合交通部{JT / 808—2013道路运输车辆卫星定位系统北斗兼容车载终端通讯协议技术规范》的标准，支持用户二次开发。
附图说明[0011] 图1为本实用新型系统原理图。
具体实施方式
[0012] 以下结合具体实施例，对本实用新型进行详细说明。
[0013] 如图1所示，北斗/ GPS定位天线接收北斗二号Rl频点信号，经过北斗定位芯片之后，将本机定位信息(定位三种模式:单北斗定位、单GPS定位、北斗/ GPS混合定位,三种模式可以由用户选择。默认为:混合定位模式)通过RS232串口发至主控板；北斗通信接收天线接收北斗s频点信号，经过低噪放之后，转换为RF信号，经过通道下变频成为TF中频信号，基带处理板接收中频信号和通道提供的CLK基准时钟信息，对北斗s频点信号进行捕获跟踪；同时，将捕获的信息通过RS232串口输出给主控板；主控板将本机定位信息通过RS232串口发给GSM网络芯片，GSM网络芯片将本机定位信息通过GSM天线的GPRS网络发出；当设备处在无GSM网络信号情况下，主控板将把本机定位信息通过北斗通信链路进行发射。过程如下:主控板通过RS232串口将需要发射的定位信息传送给基带处理板，基带处理板将待发射的信号进行BPSK调制后发给通道。通道将BPSK信号发送至功放。功放经过上变频后通过北斗通信发射天线向天空发射。
[0014] 同时，主控板将本机定位位置信息通过串口直接在本地的显示控制器直接显示。而通过WIFI，可以在WIFI可视的范围内，通过WIFI接收主控板的信号。耳机和麦克风可以与GSM网络芯片连接，完成打电话的功能。GSM模块采用M — 50芯片。
[0015] 应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本实用新型所附权利要求的保护范围。
