【摘要】：單兵作戰(zhàn)系統是在信息化戰(zhàn)爭背景下產生的。對于需要協同作戰(zhàn)的一個戰(zhàn)術小隊，每個隊員如果都能夠實時的掌握隊伍信息，戰(zhàn)斗態(tài)勢，敵我數量等信息，將極大的提升集團作戰(zhàn)能力，這其中實時獲得每個人的具體位置是最基礎也是最重要的戰(zhàn)術信息。而利用無線傳感網絡的定位技術就可以實現這一功能，無線傳感器網絡一項主要技術就是定位技術，包括自身定位技術，網絡區(qū)域內目標定位技術等。然而這種定位技術是一種相對定位，只能獲得在網絡坐標中的相對位置信息，不能跳出網絡獲得節(jié)點的絕對地理位置信息，這給需要全局感知的戰(zhàn)術小隊指揮帶來了難題。本課題正是利用無線傳感網絡的自組織和定位技術的優(yōu)勢，同時結合GPS接收機，實現GPS信號受到干擾或者無法接收到GPS信號的區(qū)域，如地下掩體戰(zhàn)斗或電磁干擾戰(zhàn)場區(qū)域，利用一個遠離干擾源的GPS信號站接收定位信息，然后通過無線傳感網絡，使網絡中的節(jié)點可以獲得定位信息，，從而實現區(qū)域化的地理定位。 論文首先闡述了實現ZigBee節(jié)點定位和GPS衛(wèi)星定位的原理，技術和方法，著重研究兩點：ZigBee技術基于RSSI的定位原理和實現方式，以及對由GPS接收機獲得的NMEA0183格式的GGA數據處理。 為了具體實現設想的功能，利用TI的CC2430/31作為定位節(jié)點模塊，首先搭建ZigBee無線網絡；然后利用CC2431內的硬件定位引擎實現節(jié)點定位；之后連接GPS與ZigBee協調器模塊用來獲得衛(wèi)星定位信息；最后測試所有實驗設備，實現了移動目標節(jié)點的地理信息定位，并選擇了兩種情況進行系統實驗，實驗結果能夠達到預期效果。
[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.
