基于PIC16F877的GSM短信收发系统设计 基于PIC16F877的GSM短信收发系统设计 内容提要：随着GSM网络的迅速普及和移动通信技术的飞速发展，新技术和新业务的开发和应用己提到十分重要的位置。利用GSM网络作为无线智能监控系统的信息传输平台是一种很有效的方法，其原理简单，安全必威体育官网网址性高，又不需要组建专用网络和维护网络，加上GSM网络覆盖面广，因此与传统的监控系统相比有着其独特的优势。 利用综合移动通信技术、计算机技术和自动控制技术成功实现了基于GSM 网络的智能监控模块的设计。该模块硬件是由两部分构成，一部分是监控主板，主要由单片机16F877A和外围电路部分、LCD部分和外围电路部分构成，主要完成对、显示功能另一部分是无线MODEM由GSM引擎TC35i及其外围电路以及串行通信和其外围电路构成，主要完成短信息的发送和接收本论文围绕单片机控制模块收发短信这一热点课题阐述了相应的GSM无线终端的设计方案、开发方法和开发过程，在设计中利用Microchip公司的8位PIC16F877A单片机和Siemens公司的必威体育精装版一代GSM模块TC35i实现了一款具有短信收发功能的GSM Mode二原型。利用此Modem原型，可以在应用系统之间以此Modem和GSM网络为纽带，实现远地数据的传输。 关键词：智能监控 GSM网络TC35i PIC16F877A SMS AT命令 ? Based on the GSM module data acquisition system SCM on the MCU Abstract: Because quick universality and ambulation of GSM network correspond by letter to technically fly to soon develop, new technique with new development and application of the business have been a very important position.Using GSM network as wireless intelligence supervision system of informations delivering platform be a kind of very valid method, it uses simpler principle is simple, safer confidentiality, and then dont need the set to set up an appropriation network and support a network, plus a GSM network to overlay noodles widely, so compare with traditional supervision system to have its special advantage. Comprehensive move a correspondence technique, calculator technique and automatically control a technique, the author successfully carried out to supervise and control a mold piece according to the intelligence of the GSM network of design.The molds piece hardware constitutes to two parts, a part is to supervise and control main plank, mainly constitute to the CPU and the outer circle part, LCD part and outer circle electric circuit, the monitor of main quantity and numerical quantity of the completion emulation, and display monitor appearance on the LCD in time;Another part is a wireless MODEM, constitute to the GSM- powered TC35i and its outer circle electric circuit, main completion send out of
