本文介绍了应用PDA组建无线IC卡表抄收系统的设计与实现。无线IC卡表抄收系统由PDA、无线转发器、微型打印机、无线lC卡表组成。PDA、无线转发器、微型打印机之间采用蓝牙技术实现通讯连接。使用时,先由PDA发送命令给无线转发器,无线转发器通过内部集成的无线收发模块发出抄表命令给安装在用户家中的无线IC卡表,无线IC卡表对接收的抄表命令做出应答,返回抄表数据并经无线转发器发送给PDA,PDA可以方便地选取用户和浏览数据,通过微型打印机现场打印抄表单,从而可实现免入户抄表,现场批量抄表,现场打印抄表单等诸多功能。
This article introduces the design and implementation of a wireless IC card meter collection system based on PDA. Wireless IC card form collection system consists of PDA, wireless repeater, micro-printer, wireless lC card form. PDA, wireless repeaters, micro-printers using Bluetooth technology to achieve communication connection. When in use, the PDA sends a command to the wireless repeater. The wireless repeater sends a meter reading command to the wireless IC card table installed in the user’s home through the integrated wireless transceiver module. The wireless IC card table makes an order for the meter reading received Answer, return the meter reading data and send it to PDA via wireless transponder, PDA can easily select users and browse data, and print the meter copy on the spot through the micro printer, so as to realize the free meter reading, on-site batch meter reading and on-site printing copy Forms and many other features.
