Smart home monitoring system based on laser sensing information

为了解决智能家居监控存在通信盲区、流量大的缺点,设计了一种基于激光感知信息的智能家居监控系统,选取STM32F103单片机作为系统核心处理器,该系统感知层利用由嵌入式控制板、传感器监控节点以及路由器组成的传感设备单元中所包含的激光传感器等传感器,感知智能家居以及环境信息,激光传感器利用谐波检测技术检测环境中气体浓度,完成信息感知后,利用传感网络组网以及协同信息处理单元的协同信息处理模块处理感知信息,将完成处理的感知信息发送至网络层,网络层利用蓝牙、无线通信网络等技术将感知结果传送至应用层,应用层将监控结果显示至监控显示界面,在智能家居存在异常情况时,通过语音报警模块实时报警。实验结果表明,所设计系统的峰值信噪比在30 dB以上,且具有270 kb/s以上的传输速率,只需检测大约6 kbit的数据量就可以对智能家居系统进行有效监控。该系统能有效地监控智能家居温度、湿度、气体浓度等指标,没有通信盲区。

In order to solve the problems of communication blind area and large flow in smart home monitoring, this paper designs a smart home monitoring system based on laser sensing information. STM32 F103 is selected as the core processor of the system The laser sensor and other sensors in the sensor equipment unit composed of sensor monitoring nodes and routers sense the smart home and environmental information. The laser sensor uses the harmonic detection technology to detect the gas concentration in the environment. After the information perception, the sensor network and the collaborative information processing module of the collaborative information processing unit are used to process the sensing information, The sensing information is sent to the network layer, the network layer uses Bluetooth, wireless communication network and other technologies to transmit the sensing results to the application layer, and the application layer displays the monitoring results to the monitoring display interface. When there is an abnormal situation in the smart home, the real-time alarm is given through the voice alarm module. The experimental results show that the peak signal-to-noise ratio of the system is more than 30 dB, and the transmission rate is more than 270 kb/s The data volume of kbit can effectively monitor the smart home system. The system can effectively monitor the smart home temperature, humidity, gas concentration and other indicators, without communication blind area.
