1、基于PIC18F4550的GSM防盗报警系统设计内容提要：随着电子、计算机和通信等技术的发展,各种智能小区、数字家园和报警系统不断出现。本文介绍了一种基于GSM的SMS业务的智能防盗报警系统,该系统充分利用最成熟的GSM移动通信网络,可实时将警情以短消息的形式发送给用户、监控中心或公安部门。该系统以其设置和控制灵活、功能可扩展、经济、便捷、及时和可普及等优点具有很大发展潜力和实用价值。本文结合PIC18F4550单片机、热释电红外、GSM等多种技术，实现了家居远程防盗报警系统。本文从PIC18F4550单片机开始，阐述了PIC18F4550单片机、热释电红外、GS
2、M的基本原理、所采用的相关技术，进而交代了GSM远程报警系统的实现方法，重点阐述了GSM在PDU模式下短信收发的实现。该设计经过测试，实现了家居远程防盗报警，达到预期的设计效果。关键词：GSM防盗报警系统、TC35i、PIC18F4550GuardagainstthefttoreporttothepoliceasystemdesignaccordingtotheGSMofthePIC18F4550Abstract:Alongwiththetechnicaldevelopments,suchaselectronics,calculatorandcorresponde
