基于GPRS和单片机的彩信报警系统设计方案本彩信报警系统以普通AT89C52 单片机和带有彩信功能的无线模块GPRS，前端设备可以根据控制摄像头采集图片，发送到用户手机上，同时用户可以通过短信命令随时查看系统状态， 或者控制前端摄像头采集图像，监控现场情况。采用此方案设计的产品操作简单，为了降低成本，在最小硬件设计的基础上，系统的功能尽可能用软件程序来实现，以达到降低成本，满足市场需求。-Based on GPRS and SCM MMS alarm system design MMS alarm system to the ordinary AT89C52 microcontroller and wireless module GPRS with MMS, the front-end equipment can be collected under the control of the camera pictures, sent to mobile phone users, while users canview the system status at any time via SMS command, or control the front-end camera image acquisition, monitoring the situation at the scene. Products with this design, simple operation, in order to reduce costs, on the basis of the minimum hardware design, the function of the system as much as possible using the software program to achieve, in order to achieve lower costs, meet market demand.
