摘要
应用AT89S52单片机为主控芯片设计了一套发票远程打印系统。该系统采用嵌入式Modem模块进行数据通信,扩展IS61LV5128进行数据存储扩展,实现了在公共电话交换网(PSTN)内进行远程控制打印设备输出税控发票的功能。经实际应用验证,该系统有效利用了普及程度最高、通信成本最低的PSTN网作为通讯媒介,远程打印控制极大降低了办公成本,具有很高的性价比。
Applied an AT89S52 MCU as the main-control chip,an invoice remote printing system was designed.The system uses embedded modem for remote data transmission and extending IS61LV5128 for data storage,the function of controlling the printer to achieve the invoices remote printing through the PSTN is realized.Application shows that it effectively utilizes the PSTN as the communication medium,greatly reduces the cost and has high performance price ratio.
