铁路道口报警及控制系统

为了保证道口行车安全,在无人监护道口设置闪光和语音报警及道口横杆控制系统,利用单片机和无线通信技术以实现列车接近道口时,道口报警闪光器和语音扬声器同时报警,并放下道口横杆;列车离开道口时,道口闪光器和语音扬声器同时关闭,并升起道口横杆。在分析和比较几种单片机和传感器的基础上,确定本系统采用MCS51系列低功耗单片机和磁电传感器。

Railway across-way alarm and controll system

In order to ensure the safety of across-way when train traveling,speech and voice alarm and block pole controlling system is installed at no-person across-way,it makes use of single-chip microcomputer and wireless communication technology to implement the function of across-way flashing light equipment and speaker alarming and put down the block pole when train passes the across-way and across-way flashing light equipment and speaker shut off and put up the block pole when train leaves the across-way.Based on analyzing and comparing of several single-chip microcomputers and sensors,MCS51 series lower power single-chip microcomputer and magnetic-electic sensor are adopted.
