【摘要】：长期以来,野生动物调查面临着许多现实困难,随着很多野生动物种群数量的逐渐减少,甚至于濒临灭绝,已经很难在野外见到活动的野生动物。同时其中有许多动物属于昼伏夜出的,具备较高的隐蔽性,还有一些仅仅生存在少有人出没的森林和其他生态环境中。现存野生动物侦测设备很多存在处理速度慢、实时性差,可持续工作时间短等弊病。随着电子技术的迅速发展,红外相机技术与数码相机技术相结合,生成出新一代数码红外相机装置,广泛应用在野生动物的种群监测、多样性调查和种群密度评估等科研和保护工作中。本文针对目前自然保护区监测野生动物的困难,设计了一种能在恶劣环境中长期工作的嵌入式无线监测系统。研究内容主要包括:第一,本系统采用图像处理能力强的双核微处理器芯片NT96450和无线通信模块H330,搭载响应速度快的u ITRON实时操作系统,并选用了带有超声电机自动控制焦距的CMOS图像传感器。当热释电红外传感器探测到野生动物后触发系统进行图像和视频数据采集,通过对采集和处理时间的优化,使系统从上电到采集完图片所需的时间保持在1.5s以内。第二,在图像和视频数据的网络传输过程中利用TCP协议栈来保证网络数据传输的可靠性。红外监控相机将处理后的图像和视频,以彩信和邮件的方式即时上传给用户,信号强度不够的情况下启用重发机制保证了数据发送的成功率。第三,设计和实现了四大模块功能,分别是数据采集与存储、参数设置、远程监控和远程报警等模块。软件系统运行的稳定性也较大程度保证了可持续工作的时间长度。本文在完成整个红外相机软件系统的设计后,还对系统的主要功能模块进行了功能性测试和性能测试。由测试结果表明,系统设计的各个功能模块都能正常实现,满足了嵌入式系统设计的可靠性、稳定性和经济性。
[Abstract]:For a long time, wildlife investigation has been faced with many practical difficulties. With the decline of the population of many wild animals and even the imminent extinction, it is difficult to see wild animals in the wild. At the same time, many of the animals are nocturnal, with high concealment, and some only exist in the few inhabited forests and other ecological environments. Many of the existing wildlife detection equipment have disadvantages such as slow processing speed, poor real-time, short sustainable working time and so on. With the rapid development of electronic technology, the combination of infrared camera technology and digital camera technology has produced a new generation of digital infrared camera devices, which are widely used in wildlife population monitoring. Diversity survey and population density assessment and other scientific research and conservation work. In view of the difficulties of wildlife monitoring in nature reserves at present, an embedded wireless monitoring system which can work in harsh environment for a long time is designed in this paper. The main research contents are as follows: first, the system uses a dual-core microprocessor chip NT96450 and a wireless communication module H330, which has strong image processing ability, to carry the u ITRON real-time operating system with high response speed. CMOS image sensor with ultrasonic motor automatic control focal length is selected. When the pyroelectric infrared sensor detects wild animals, the system triggers the image and video data acquisition. By optimizing the acquisition and processing time, the time required for the system from power on to finish collecting pictures is kept within 1.5 seconds. Secondly, TCP protocol stack is used to ensure the reliability of network data transmission. Infrared surveillance camera can upload the processed image and video to the user by MMS and email. When the signal intensity is not enough, the retransmission mechanism can ensure the success rate of data transmission. Thirdly, four modules are designed and implemented, which are data acquisition and storage, parameter setting, remote monitoring and remote alarm. The stability of software system also ensures the duration of sustainable work. After completing the design of the whole infrared camera software system, the main function modules of the system are also tested in function and performance. The test results show that each functional module of the system design can be realized normally, which satisfies the reliability, stability and economy of the embedded system design.
