摘 要
个人数据交换PDI(Personal Data Interchange)每时每刻都进行着，可以是两个人面对面、通过电话或网络的信息交流，同其他人一起的信息共享。通过纸质名片，或者电子名片来进行信息的交换。
该课题研究首先围绕vCalendar结构，阐述了什么是vCalendar，产生过程以及应用范围。对其组织结构和主要字段：DTSTART、DALARM、DTEND等在结构中作用，以及各属性取值，编码间的转换作了详细分析；然后结合Motorola L7型号手机，测试出手机特性，功能操作流程、系统编码方式、读取开关、配置信息、数据格式构成等。可以实现操作有：下载、新增、修改、删除。再根据每一功能特性，制定出实现方式。主要是重写基类接口函数，来达到对该手机型号的支持，再把插件加入到软件架构中，设计出能在PC和手机端通信的软件。通过该软件可以对手机中的事件、日程安排进行操作，同时也可以同WINDOWS系统进行数据同步。

The design of the vCalendar`s cross-platform system
Abstract
Personal Data Interchange (PDI) occurs every time, Two or more individuals communicate in either face-to-face or across wire and internet data. Such interchanges frequently include the exchange of informal information, such as business cards paper cars or Vcards.
The topic is based on the construction of vCalendar, expounded what is vCanlendar, the process of having it and the applications. Especially it explains the histological structure and the function for key fields-DTSTART, DALARM and DTEND,the value of each attribution and the transforms between the codes; Combined with Motorola L7 to get the property of the mobile-phone, operation flow of the functions, methods of system coding, switches reading, configuration messages and the forming of data compositions, etc. Effected operations could be: downloading, adding, revising and deleting, and fulfilling the methods with the functional characters, Main point is re-writing basic port function to get the compatibility of the mobile. Then, add the x-activitis into the software, obtain the communications between PC and cell-phone; which can either control the events, schedule in for the mobile, or make the data synchronization with Windows system.
