基于ARM和Zigbee技術的室內環(huán)境無線監(jiān)測系統設計與實現
[Abstract]:With the development of computer technology, wireless sensor network technology and embedded technology, the application of multi-technology integrated embedded system in people's production and life is more and more extensive. Along with the rapid development of economy, China's industrialization level has been continuously improved, and it has also brought serious environmental pollution and safety problems. Many problems such as haze shrouding, harmful gas volatilization and leakage, indoor fire theft and so on occur frequently. It is a serious threat to people's health and life and property safety, so the demand for real-time monitoring of indoor environment is becoming more and more important. The current environmental monitoring technology and equipment lag relatively, the environmental monitoring means are single, the monitoring range is small, it is difficult to realize the real-time and effective monitoring of indoor environment, the performance of embedded indoor environment monitoring system based on wireless sensor network technology is superior. It has the advantages of low cost, flexible networking, simple wiring and good expansibility. Therefore, this paper proposes a wireless monitoring system for indoor environment based on ARM and ZigBee technology. It takes S3C2440 processor and CC2530 wireless sensor network module as hardware platform, carries Linux operating system, and selects indoor temperature and humidity. The environmental parameters such as gas leakage and invasion status of outsiders are used as monitoring objects to realize real-time monitoring and monitoring of indoor environment and security conditions as well as network video surveillance functions. This paper first introduces the present situation of indoor environmental monitoring, analyzes the task requirements of the system and designs the overall scheme of the system, and completes the analysis and selection of the hardware platform and components of the system, as well as the related circuit design. Then the bottom software environment of the system development is constructed, and the custom porting of Linux system and the transplantation of related software tools are completed. Finally, the system software program design, including ZigBee wireless network module program, network video monitoring program arm data processing program and so on, is described. The graphical user interface of the system and the remote monitoring interface of the network are designed. By testing the software and hardware of the system model, the results show that the system achieves the basic function and achieves the expected effect. The final functions are: 1) indoor environmental information collection and wireless network transmission 2) local real-time monitoring and display of indoor environment 3) remote monitoring and video monitoring of indoor environmental conditions.
