Design And Implementation Of Software System On The Multi-function Infrared Monitoring Camera

For a long time,the wildlife survey has faced many practical difficulties.With the gradual reduction of the number of wild animal populations,and even the endangered,it has been difficult to see wild animals in the wild.At the same time there are many animals belonging to the day and night out,with a high degree of concealment,and some only survived in rare forest and other ecological environment.Existing wild animal detection equipment,there are many processing speed is slow,real-time poor,short working hours and other shortcomings.With the rapid development of electronic technology,infrared camera technology and digital camera technology combined to generate a new generation of digital infrared camera device,widely used in wild animal population monitoring,diversity survey and population density assessment and other research and protection work.This paper designs an embedded wireless monitoring system which can work in harsh environment for a long time in view of the difficulty of monitoring wildlife in nature reserve.The main contents of the study include:Firstly,the system uses image processing capacity of dual-core microprocessor chip NT96450 and wireless communication module H330,equipped with fast response u ITRON real-time operating system,and selected with ultrasonic motor automatic control focal length CMOS image sensor.When the pyroelectric infrared sensor detects the wild animal after the trigger system for image and video data acquisition,through the acquisition and processing time optimization,the system from power to the collection of pictures required time to keep within 1.5s.Secondly,in the image and video data transmission network using TCP protocol stack to ensure the reliability of network data transmission.Infrared surveillance camera will be processed after the image and video to MMS and e-mail instantly uploaded to the user,the signal strength is not enough to enable the retransmission mechanism to ensure the success rate of data transmission.Thirdly,the design and implementation of data acquisition and storage modules,parameter setting module,remote monitoring module,remote alarm module and other functions.The stability of the software system operation also ensures a longer degree of sustainable work.In this paper,after the completion of the entire infrared camera software system design,but also the main functional modules of the system for functional testing and performance testing.By the test results show that the system design of the various functional modules can be achieved normally,to meet the embedded system design reliability,stability and economy.
