基于PDA的固定资产管理系统的设计与开发
摘 要
固定资产是企业、事业单位的重要资源。对固定资产进行管理,是保证固定资产合理利用的前提。当前企事业单位业务迅速拓展,业务信息也逐步深入,面对庞大数量,分支结构较多,资产种类繁多,资产分布面积广等情况,若仍采用传统的固定资产管理方式,如手工管理,以表格的形式体现,会相当麻烦,而且降低了工作效率,浪费管理人员的精力与时间,增加了成本。目前现有的开发在PC机上的资产管理系统依然需要手工录入数据,对资产的生命周期的跟踪还是不够完善,因此开发基于PDA资产管理系统是十分必要的,它可以与现有资产管理系统搭配使用,可以更好地对资产进行管理。
采用RFID射频技术,可以为用户提供快捷的资产数据收集,统计,管理,也可以实现对整个资产生命周期包括采购,盘点,变动,报废等跟踪管理。PDA是个人掌上电脑,体积很小,可以随处移动。本系统是基于PDA上运行,采用RFID技术对资产进行跟踪管理,它包含了三大业务模块:资产盘点,资产变动,资产报废。在这三个功能模块里,可以利用RFID读写技术对资产进行扫描确认,进行标签制作等,通过同步工具,可以把原有PC机上的资产管理的数据下载到PDA,把PDA上处理的数据上传到PC机上。本系统可以大大减少人工统计的误差,提高数据的准确性,也极大提高工作效率,为企业管理资产提供更科学的方法。
本系统采用MVC分层设计思想,统一建模语言,SQLite数据库技术,RFID技术,是一个基于PDA移动设备上开发的资产管理系统。

The Design and Development of Fixed Asset Management System based on PDA
ABSTRACT
Fixed asset is the important resource to enterprises and organizations. Asset management ensures the rational use of fixed assets. Nowadays, with rapidly expanding business, huge amount of business information, more and more branches, using the traditional fixed asset management mode, such as manual management, reflected in table form, can be quite troublesome, reduce the working efficiency, waste management personnel's energy and time, and increase the cost. The original asset management system developed in PC still requires manual data input. The tracking of asset life cycle is also not perfect. Therefore, an asset management system based on PDA development is very necessary. It can provide a better asset management if used with the original asset management system.
RFID technology can provide users with quick assets data collection, statistics and management. It also can achieve the tracking management for the whole asset life cycle including assert purchasing, inventory, change, retirement and etc. PDA is a personal computer in hand. Its volume is small, and it can be carried to everywhere. This system is designed and developed based on PDA, using RFID to track assets management. It contains three business modules: asset inventory, asset changing and asset retirement. In these three function module, it adopts RFID literacy technology to scan and confirm asset and make labels. By using synchronizing tools, it can download the original asset management data from PC to the PDA, and upload the processed data from PDA to PC. This system can greatly reduce the error, increase the artificial statistical data accuracy, and also greatly improve work efficiency and provide a more scientific method for enterprise to manage assets.
The system development applies the MVC design pattern, UML (Unified Modeling Language), SQLite database technology, RFID technology, and is developed based on PDA mobile device.
