Description

多功能PDA
技术领域：
本实用新型涉及一种便携式信息技术设备。特别是涉及一款具备全球定位、跟踪导航功能的掌上设备。
背景技术：
当前，具备全球定位功能的便携式或手持设备在市场上比较广泛，其缺点是功能单一，仅对持机人提供导航信息，他人无法了解持机人的地理位置；市场上目前已有的GPS+GSM组合的信息产品，其原理是GPS短信方式发送至服务中心或特定目标，以供他人了解持机人的地理位置。但这些产品都定位于跟踪导航的应用，无法满足用户进行移动信息管理、办公的需要。
发明内容：
本实用新型的目的在于克服上述不足，提供一种能满足用户进行移动信息管理、办公的需要的多功能PDA。
本实用新型的目的是这样实现的：一种多功能PDA，其特点是它包括外壳、内部线路板、中央处理器单元、FLASH存储器、SDRAM存储器、GPS接收器、GSM/GPRS/CDMA模块、USB接口以及LCD液晶显示屏和触摸屏，FLASH存储器、SDRAM存储器、GPS接收器、GSM/GPRS/CDMA模块、USB接口以及LCD液晶显示屏和触摸屏均与中央处理器单元相连，中央处理单元、FLASH存储器、SDRAM存储器、GPS接收器和GSM/GPRS/CDMA模块集成在外壳内部的线路板上，外壳正面有LCD液晶显示屏和触摸屏，侧面是USB接口插座。
本实用新型还可在内部线路板上集成电子地图存储卡接口，电子地图存储卡接口与中央处理器单元相连，外壳侧面有电子地图存储卡接口插座。电子地图存储卡接口可插置电子地图存储卡，。
本实用新型也可在内部线路板上集成条形码扫描设备接口，条形码扫描设备接口与中央处理器单元相连，外壳侧面有条形码扫描设备接口插座。
本实用新型也还可在内部线路板上集成有指纹识别模块，指纹识别模块与中央处理器单元相连，外壳正面有指纹识别窗口。
本实用新型为一种便携式信息技术设备。是以全球定位系统(GPS)、电子地图(CF)存储、GSM/GPRS/CDMA通信为基础，增加了嵌入式数据管理系统、条形码扫描技术、LCD显示、触摸屏控制、指纹识别、USB接口等功能于一体，构造了一个完整的各功能模块可重组的移动信息管理平台，以适应用户进行移动信息管理的需要。本实用新型插拔灵活的CF存储卡能在多个设备上使用，通过相关移动通信网络，可将地理位置信息发送至设定目标或指定手机上；本实用新型结合嵌入式数据库管理系统、条码扫描设备，构造了一款移动管理信息终端，较适合物流等领域的应用。
附图说明：
图1为本实用新型的逻辑框图。
图2为本实用新型的外观图。
具体实施方式：
如图1，本实用新型是一款便携式(手持)信息技术设备——多功能PDA，主要由外壳12、内部线路板13、中央处理器单元5、FLASH存储器4、SDRAM存储器8、条形码扫描设备接口1、指纹识别模块2、GPS接收器7(全球定位系统)、GSM/GPRS/CDMA模块11、USB接口10、电子地图(CF)存储卡14、CF存储卡接口3、LCD液晶显示屏9和触摸屏6、电源开关按钮16、功能切换按钮17、指纹识别窗口15和电池仓等组成。FLASH存储器4、SDRAM存储器8、条形码扫描设备接口1、指纹识别模块2、GPS接收器7、GSM/GPRS/CDMA模块11、USB接口10、电子地图存储卡接口3以及LCD液晶显示屏9和触摸屏6均与中央处理器单元5相连。中央处理器单元5、FLASH存储器4、SDRAM存储器8、条形码扫描设备接口1、指纹识别模块2、GPS接收器7和GSM/GPRS/CDMA模块11集成在外壳12内部的一块线路板13上。
如图2，设备外壳12正面上方是LCD液晶显示屏9和触摸屏6，下方是电源开关按钮16、功能切换按钮17和指纹识别窗口15，背面是电池仓；外壳侧面分别是USB接口插座21、CF存储卡接口插座20，设备底端是条形码扫描设备接口插座22，顶端分别是GPS接收器天线、GSM/GPRS/CDMA天线连接底座18、19。
中央处理单元是本设备数据处理的核心，其核心采用32位精简指令集的微处理器；配置16MB以上SDRAM存储器，作为程序运行空间；软件固化于FLASH存储器，同时提供CF卡存储卡接口，以供存储电子地图的CF存储卡插入，卡上的电子地图等数据可经过USB接口从计算机上下载；GPS接收器接收全球定位信号，获得当前位置的经纬度坐标，速度、方位等传递给中央处理器单元；GSM模块可接入中国联通或中国移动的移动通信网络，在中央处理器单元控制下与设定对象进行数据(短信方式)或语音通信，如发送和接收本机数据库中的数据，以实现移动信息管理的目标；条形码扫描接口供条码扫描设备接入，以获得相关条形码数据加入本机数据库中；为方便用户操作，本机仅设电源开关、功能切换等几个按键，大部分操作通过按触摸屏来完成；指纹识别是为增强本实用新型的安全性而设定，只有通过指纹识别的用户才能使用本设备，LCD显示屏实时显示电子地图和用户界面等信息。
