介绍了一种用于高速公路(或类似的野外环境)中的实时短信报警系统。该系统以STC12LE5A60S2单片机为控制中心,利用压片传感器采集震动信号,再控制SIM900A模块与GSM网络连接,可完成对高速公路上事故信息的采集,并转化为事故报警信息发送到监控平台上,实现了高速公路上实时、主动、准确的事故报警。该系统成本低、功耗小,无需市电供电,克服了高速公路管理部门被动获取事故信息的缺点,具有良好的应用前景。
介紹瞭一種用于高速公路(或類似的野外環境)中的實時短信報警繫統。該繫統以STC12LE5A60S2單片機為控製中心,利用壓片傳感器採集震動信號,再控製SIM900A模塊與GSM網絡連接,可完成對高速公路上事故信息的採集,併轉化為事故報警信息髮送到鑑控平檯上,實現瞭高速公路上實時、主動、準確的事故報警。該繫統成本低、功耗小,無需市電供電,剋服瞭高速公路管理部門被動穫取事故信息的缺點,具有良好的應用前景。

This paper introduces a real-time SMS alarm system which used for highway( or similar field environ-ment). STC12LE5A60S2 microcontroller is the control center of this system. It uses pressure sensor to complete the vibration signal acquisition and connects to GSM network through SIM900A. Thus vibration signal can be converted to accident alarm information and sent to the monitoring platform,realizing a real-time,active and accurate accident alarm function on the highway.
