基于LabVIEW和物联网的分布式家庭智能监控系统

为了解决现有家庭监控系统的不足，基于ZigBee无线自组网技术，利用”软件代替硬件”的设计理念，设计了一种分布式家庭智能监控系统。该系统以采用CC2530作为主控芯片，选择合适的硬件设计了用于门窗防盗、视频监控、温湿度监控、智能控制和USB数据传输的接收机等功能模块，编制了相应的下位机监控程序，利用LabVIEW软件开发了上位机网络远程智能监控软件。该系统硬件安装在现场，通过运行上述监控软件和无线通讯，可以实现燃气浓度、温湿度、门窗状态的实时监测、视频实时监控和数据的无线传输，并可以实现通过互联网通信进行远程监控。通过实验测试可知，该系统还可以实现现场报警、历史记录存储和远程网络智能监控等功能，具有体积小、成本低、无需开槽安装、便于扩展、智能化程度高和性能稳定可靠等优点。

Home Distributed Intelligent Monitoring System Based on LabVIEW and Internet of Things

In order to solve the shortage of the existing home monitoring systems, a distributed intelligent monito- ring system is designed based on ZigBee wireless and hoc network technique and the design concept of software replacing hardware. CC2530 was selected as master control chip in this system, and other appropriate hardware were chosen to design function modules, which include doors and windows monitoring module, video monitoring module, temperature and humidity monitoring module, intelligent control module and USB data transmission module and so on. The network remote intelligent monitoring software operating in upper computer was developed based on LabVIEW, and the corresponding monitoring program operating in slave computer was also developed. When the hardware of this system was installed in the field, the video real - time monitoring data and the data of gas density, temperature and humidity, doors and windows state were acquired by the above monitoring software and function modules and were transmitted to the PC through wireless communication and USB interface. All function modules and the operating states could be monitored and controlled by using the Interact communica- tion. The experiment results showed that the functions of field alarming, historical records storing and remote net- work intelligent monitoring can be achieved effectively by using this system. The designed system has other ad- vantages, including small volume, low cost, no groove installation, easy to expand, high intelligent degree, sta- ble and reliable performance and so on.
