【摘要】：單兵作戰(zhàn)系統(tǒng)是在信息化戰(zhàn)爭(zhēng)背景下產(chǎn)生的。對(duì)于需要協(xié)同作戰(zhàn)的一個(gè)戰(zhàn)術(shù)小隊(duì)，每個(gè)隊(duì)員如果都能夠?qū)崟r(shí)的掌握隊(duì)伍信息，戰(zhàn)斗態(tài)勢(shì)，敵我數(shù)量等信息，將極大的提升集團(tuán)作戰(zhàn)能力，這其中實(shí)時(shí)獲得每個(gè)人的具體位置是最基礎(chǔ)也是最重要的戰(zhàn)術(shù)信息。而利用無(wú)線傳感網(wǎng)絡(luò)的定位技術(shù)就可以實(shí)現(xiàn)這一功能，無(wú)線傳感器網(wǎng)絡(luò)一項(xiàng)主要技術(shù)就是定位技術(shù)，包括自身定位技術(shù)，網(wǎng)絡(luò)區(qū)域內(nèi)目標(biāo)定位技術(shù)等。然而這種定位技術(shù)是一種相對(duì)定位，只能獲得在網(wǎng)絡(luò)坐標(biāo)中的相對(duì)位置信息，不能跳出網(wǎng)絡(luò)獲得節(jié)點(diǎn)的絕對(duì)地理位置信息，這給需要全局感知的戰(zhàn)術(shù)小隊(duì)指揮帶來(lái)了難題。本課題正是利用無(wú)線傳感網(wǎng)絡(luò)的自組織和定位技術(shù)的優(yōu)勢(shì)，同時(shí)結(jié)合GPS接收機(jī)，實(shí)現(xiàn)GPS信號(hào)受到干擾或者無(wú)法接收到GPS信號(hào)的區(qū)域，如地下掩體戰(zhàn)斗或電磁干擾戰(zhàn)場(chǎng)區(qū)域，利用一個(gè)遠(yuǎn)離干擾源的GPS信號(hào)站接收定位信息，然后通過(guò)無(wú)線傳感網(wǎng)絡(luò)，使網(wǎng)絡(luò)中的節(jié)點(diǎn)可以獲得定位信息，，從而實(shí)現(xiàn)區(qū)域化的地理定位。 論文首先闡述了實(shí)現(xiàn)ZigBee節(jié)點(diǎn)定位和GPS衛(wèi)星定位的原理，技術(shù)和方法，著重研究?jī)牲c(diǎn)：ZigBee技術(shù)基于RSSI的定位原理和實(shí)現(xiàn)方式，以及對(duì)由GPS接收機(jī)獲得的NMEA0183格式的GGA數(shù)據(jù)處理。 為了具體實(shí)現(xiàn)設(shè)想的功能，利用TI的CC2430/31作為定位節(jié)點(diǎn)模塊，首先搭建ZigBee無(wú)線網(wǎng)絡(luò)；然后利用CC2431內(nèi)的硬件定位引擎實(shí)現(xiàn)節(jié)點(diǎn)定位；之后連接GPS與ZigBee協(xié)調(diào)器模塊用來(lái)獲得衛(wèi)星定位信息；最后測(cè)試所有實(shí)驗(yàn)設(shè)備，實(shí)現(xiàn)了移動(dòng)目標(biāo)節(jié)點(diǎn)的地理信息定位，并選擇了兩種情況進(jìn)行系統(tǒng)實(shí)驗(yàn)，實(shí)驗(yàn)結(jié)果能夠達(dá)到預(yù)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.
