中文摘要：

基于启东斯迈特S51E开发板，设计开发了一套智能报警系统。该系统以AT89S52单片机为控制核心，采用SIEMENS3618手机作为GSM模块发送报警信息。单片机通过串口连接GSM模块，串口波特率为19．2k。单片机成功地与GSM模块进行了通信，并能够通过GSM模块以及GSM网络向指定手机号码发送报警短信。其设计思想和工作原理可应用于工作环境差的少人或无人值守岗位的智能化管理，提高报警的实时性并降低管理成本。

英文摘要：

Describe a household alarming system based on S51E module, using MCU AT89S52 as the core unit. SIEMENS3618 mobile phone is used as the GSM module to send alarm messages to the GSM network. The MCU communicates with the GSM module through a RS232 serial port, with baud rate setting to 19.2k. In experiments the MCU communicated with the mobile phone successfully, sending the alarm message to the other specified mobile phone number through the GSM network. It is believed that such systems can be of much help in the intelligent management of unmanned posts where the environments of work are often tough, shortening alarming time and reducing management cost.
