基于无线传输的客车自动破窗及区域救援系统

The system of automatic broken window and regional rescue for coach based on wireless transmission technology

为了防止大客车在发生火灾、侧翻事故时乘客不能及时破窗而造成的大规模乘客伤亡事件发生,基于无线通讯技术和自动控制原理,设计了一种进行区域联动救援的大客车紧急破窗系统。本系统采用烟雾传感器和二氧化碳传感器检测火灾信号,组合传感器由重力传感器、碰撞传感器和加速度传感器集成,用于检测侧翻信号;采用单片机接收信号,当判定事故发生,控制破窗装置实现破窗,同时控制zigbee无线通讯技术实现寻求区域联动救援和SIM900A无线通信模实现相关部门远程求救。通过模拟实验验证:系统可以有效的提高事故发生时自动破窗的准确性和及时性,并能够及时实时近程区域联动救援和远程报警求救。

In order to prevent the casualties which caused by passengers failing to break windows and being unable to be rescued promptly after a coach accident of the fire or rollover, the coach regional linkage rescue and emergency broken window system is designed based on Wireless transmission technology and automatic control principle. The smoke sensor and CO2 sensor were used to detect fire signals; the combination sensor which was integrated by a gravity sensor, a collision sensor, and an acceleration sensor was used to detect a rollover sig- nal; the SCM was adopted to receive the signal, when the accident was judged, the broken window device was controlled to break windows by the $CM, at the same time the zigbee wireless communication technology and SIM900A wireless communication module were controlled to achieve regional cooperation rescue and remote assistance respectively. The simulation results show that the accuracy and timeliness of the broken window device was improved by the system, and it can complete timely rescue and remote alarms in real-time and near-range areas.
