在突发安全事故中,人群混乱、无序会给人身安全带来危害.为克服传统应急系统不能第一时间有效组织人员快速撤离、进行自救的不足,设计了集自动控制技术、无线通信技术及人机交互技术于一体的智能应急通知系统.该系统利用现有广播系统及对讲机等常规通信设备,基于串口通信的无线对讲收发模块,选用集成度高、可靠性好的STC12C5A60S2微控制器,实现了8分区的独立可控.试验结果表明,当通信距离为3.5 km时,该系统的数据传输正确率可达100％,正常响应时间短,无需专人值守.%In the burst security incidents,the condition of crowd chaos and disorder may bring personal safety hazards.To overcome the disadvantage of the traditional emergency system cannot effectively organize personnel rapid withdrawal and self-help at the first time.Thus the intelligent emergency notification system that integrates automatic control technology,wireless communication technology and man machine interactive technology is designed.The system composes of conventional communication equipment,e.g.,existing broadcasting system and walkie-talkies; and serial communication based wireless intercom transceiver module; and highly integrated and reliable micro controller STC12C5A60S2; to implement 8 of independent controllable sections.The experimental results show that in 3.5 km communication distance,the accuracy rate of data transmission of the system is 100％,normal response time is short,and the system is without staff on duty.
