【摘要】：单兵作战系统是在信息化战争背景下产生的。对于需要协同作战的一个战术小队，每个队员如果都能够实时的掌握队伍信息，战斗态势，敌我数量等信息，将极大的提升集团作战能力，这其中实时获得每个人的具体位置是最基础也是最重要的战术信息。而利用无线传感网络的定位技术就可以实现这一功能，无线传感器网络一项主要技术就是定位技术，包括自身定位技术，网络区域内目标定位技术等。然而这种定位技术是一种相对定位，只能获得在网络坐标中的相对位置信息，不能跳出网络获得节点的绝对地理位置信息，这给需要全局感知的战术小队指挥带来了难题。本课题正是利用无线传感网络的自组织和定位技术的优势，同时结合GPS接收机，实现GPS信号受到干扰或者无法接收到GPS信号的区域，如地下掩体战斗或电磁干扰战场区域，利用一个远离干扰源的GPS信号站接收定位信息，然后通过无线传感网络，使网络中的节点可以获得定位信息，，从而实现区域化的地理定位。 论文首先阐述了实现ZigBee节点定位和GPS卫星定位的原理，技术和方法，着重研究两点：ZigBee技术基于RSSI的定位原理和实现方式，以及对由GPS接收机获得的NMEA0183格式的GGA数据处理。 为了具体实现设想的功能，利用TI的CC2430/31作为定位节点模块，首先搭建ZigBee无线网络；然后利用CC2431内的硬件定位引擎实现节点定位；之后连接GPS与ZigBee协调器模块用来获得卫星定位信息；最后测试所有实验设备，实现了移动目标节点的地理信息定位，并选择了两种情况进行系统实验，实验结果能够达到预期效果。
[Abstract]:Single combat system is produced under the background of information war. For a tactical team that needs to cooperate in combat, if each team member can grasp the information of the team, the battle situation, the number of the enemy and ourselves in real time, it will greatly enhance the group's combat capability. It is the most basic and important tactical information to get the position of everyone in real time. This function can be realized by using the localization technology of wireless sensor network. One of the main technologies of wireless sensor network is localization technology, including self-localization technology, target location technology in the network area and so on. However, this location technology is a relative location, which can only obtain the relative position information in the network coordinates, and not jump out of the network to obtain the absolute geographic location information of the nodes, which brings difficulties to the tactical team command which needs global perception. In this paper, the advantages of self-organization and localization technology of wireless sensor networks are used to realize the areas where GPS signals are interfered or cannot be received by GPS signals, such as underground bunker combat or electromagnetic interference battlefield area, combined with GPS receiver. A GPS signal station far from the interference source is used to receive the location information, and then the nodes in the network can get the location information through the wireless sensor network. In this paper, the principle, technology and method of implementing ZigBee node positioning and GPS satellite positioning are introduced. The principle and implementation of two-point: ZigBee technology based on RSSI, and the GGA data processing of NMEA0183 format obtained by GPS receiver are studied in detail. In order to realize the envisaged function, the CC2430/31 of TI is used as the location node module, and the wireless network of ZigBee is built firstly, and then the node location is realized by using the hardware positioning engine in CC2431. Then the GPS and ZigBee coordinator module are connected to obtain the satellite positioning information. Finally, all the experimental equipments are tested, the geographic information location of the moving target node is realized, and two kinds of cases are selected to carry out the system experiment. The experimental results can achieve the desired results.
