1、基于 GSM 的跟踪定位技术研究及其实现 摘要 随着社会的而发展和技术的进步，基于位置的信息服务开始备受关注 ,物流监控、学生监护、老弱病残追踪符理、司法监视以及企业移动丨 .作队伍符理等方而也出现丫丨 L 大的技术需求。 H 前位 S 倍 &的服务系统大多基于 GPS 定位与专业地阌标定的方法 ,致使成木居高不下，而且由于 GPS的技术原因，在室内、林荫道、地下室等多种环境下无 法接收信兮，使其矩位服务功能受到一矩影响。近年來基于 GSM通倍网络基站的走位技术开始餅露头角 ,GSM基站记位不受环境限制 ,相比 GPS定位技术，费用极低 ,同时 Google 公 W推出的免费地图 Google

2、 Map 使得传统的记位地图标注业务现在只需要很小的代价就可以实现。这鸣技术 一 n和 K他应用领域结合，那就能带来 j (人的商机。 本文在研究 GSM 定位基础上提出了一种基于 GSM Modem 和 Google Map API 的跟踪记位技术及其实现的软硬件解决方案。该方案借助 MCI*和 GSM模块实时获取移动终端附 近移动通信网络基站的信息 ,以短信息的形式发送给监控中心，监控中心计算机通过连接的 GSM Modem 获取短信息，提取短信中关于移动终端 H 前距离城近基站的位置编码信息，并以此为条件通过 D 动 Web 页面査询技术获取丛站经纬度数据，然后利用应用程序中嵌入的Goo

3、gle Map 电子地图的 APT 相关功能，实现在电子地图上位置的标定，从而实现 / S于GSM的跟踪定位技术演示系统的完憋软硬件系统。 基于 GSM基站定位技术仅仅能够获取测试的大体位置，似考虑到 H 前我闻 GSM网络基站密度较高，在人城山 的主城区，测试结果表明定位 精度可以达到 100米至 150米左右。同时 Google Map API 又提供了一种性价比极高的地图应用程序开发方案，综合使用 GSM Modem和 Google Map API可以快速构建电子地图上当前位置的标定。这种技术略作改动即可在定位服务精度要求不高的应用领域，诸如跟踪定位系统、物流监控、学生监护、老弱病残追踪

4、管理等方面均可发挥积极的作用。 关键词 ： GSM， 定位技术， AT指令，短消息，谷歌地图 Research and Realization of Location and Tracking Technology Based on GSM ABSTRACT As the society development and the progress of technology, the people pay much altention to Che informalion service based on location, have huge technical requirements on

5、 logistics monitoring, students care, weak, sick tracking management judicial surveillance and enterprise mobile work team management. Now， the most position information service system are all based on the method of GPS positioning and professional calibration map， all this make the cost highly， and

6、 because of the GPS technology reason, in the interior, avenue， basement, etc DuoZhong environment cant receiving signals, make its location service functions have been certain eftect.the positioning technology base based on GSM communication network station make their debut in recent years， GSM bas

7、e station location compared with GPS positioning technology cant limit with environmental, low cost, and at the same time, Google company launched a free Map Google Map of the location and makes traditional Map mark business need now is a small pricc to pay can be achieved. These technology once and

8、 other applications that can be combined with the enormous business opportunities. This paper Based on the research based on GSM positioning put forward based on the GSM Modem and Google Map of the API tracking technology and its realization of hardware and software soIutions.The scheme with MCU and

9、 GSM module for real-time mobile terminal of the base near the mobile communication network information, and to short of information send forms the monitoring center, the monitoring center computer through the GSM Modem connection for short messages, extracting information about mobile terminal at p

10、resent the location of the nearest base station coded information, and lakes it as a condition through the automatic Web page inquires the technology is the acquisition of a base station longitude and latitude data, and by using the application or the embedded Google Map electronic Map relevant func

11、tion, thus realizing ihe API electronic Map, so as to realize the calibration of position based on GSM tracking technology demonstration system of the integrity of the soil ware and hardware systems. Based on GSM base station location technology can only obtain the Outlines of the test, but consider

12、ing the current position in GSM network base station higher density, in Che big cities of the test results show that the main urban areas, positioning accuracy can reach 100 in to 150 m.At the same time Google Map apis and provides a high ratio of the Map application development plan, the comprehens

13、ive use GSM Modem and Google Map API can quickly building electronic Map ihe current position of the calibralion.This technology can be offered little changes in positioning accuracy is not high service the application Held, such as tracking system, logistics monitoring, students care, weak track management which all can play an active role.
