基于GSM短信息的无线微型打印机设计

摘要

对微型打印机的控制方式主要有短距离的有线通信,以太网通信和无线蓝牙通信等,还没有出现基于短信息的远距离无线通信方法.鉴于此,设计一款基于GSM短信息的无线微型打印机.所打印的信息通过手机以短信息的方式发送给打印机,真正实现不受地点限制的无线打印.打印机以华为的GSM模决GTM900C和高性能MCS-51单片机为控制核心,以思普瑞特的微型打印机为控制对象.文章介绍了GTM900C与单片机,单片机与微型打印机之间的硬件接口电路设计,给出短信息的编码和解码内容,以及如何在单片机中集成国标码.%The control methods for micro printer mainly were short-distance communication of cable,Ethernet communications and wireless Blue-tooth communication, has no long-range wireless communication method which based on short message. In view of this,design a wireless micro printer based on GSM short message. The printed information will be send to the printer through short message of mobile phone,and not place restrictions on the wireless print truly. Printer and it's control core by Huawei's GSM module GTM900C and high performance MCS-51 microcontroller and Spirit micro printer as the control object. This paper introduces GTM900C and microcontroller, microcontroller and micro printer hardware circuit interface design,gives the encoding and decoding content of short message, and how to integrate the GB2312 code in microcontroller.
