摘 要:在研究传统家用燃气报警器的基础上,以ZigBee协议为平台,构建mesh网状网络实现网络化的智能语音报警系统。由于传感器本身的温度和实际环境温度的影响,传感器标定后采用软件补偿方法。为了减少系统费用,前端节点采用半功能节点设备,路由器和协调器采用全功能节点设备,构建mesh网络所形成的家庭内部报警系统,通过通用的电话接口连接到外部的公用电话网络,启动语音模块进行报警。实验结果表明,在2.4 GHz频率下传输,有墙等障碍物的情况下,节点的传输距离大约为35 m,能够满足家庭需要,且系统工作稳定,但在功耗方面仍需进一步改善。On the basis of studying traditional household gas alarm system, this paper proposed the platform for the ZigBee protocol,and constructed mesh network to achieve network-based intelligent voice alarm system. Because of the sensor temperature and the actual environment temperature, this system design used software compensation after calibrating sensor. In order to reduce system cost, semi-functional node devices were used as front-end node, however, full-function devices were used as routers and coordinator,constructed alarm system within the family by building mesh network,connected to the external public telephone network through the common telephone interface, started the voice alarm module. The results indicate that nodes transmit about 35m in the distance in case of walls and other obstacles by 2.4GHz frequency transmission, this is able to meet family needs and work steadily, but still needs further improvement in power consumption.
