The Design Of Remote Radiation Monitoring Terminal Based On WinCE

In recent years,with nuclear technology applied in various fields,the security of radioactive source is become more and more attention.According to statistics,most of radiation accidents are caused by radioactive source.Therefore, the radioactive source security management is important.We designed a remote radiation monitoring terminal based on WinCE for the situation of the radioactive source used in chemical factory which will produce γ-ray.In order to meet the need of radiation monitoring and the radioactive source security management.We achieved the video surveillance module and the radiation monitoring module,then integrating them.For the hardware,we choose the I.MX27as multimedia processor,radiation data collection make up with G-M tube and MSP430MCU,camera is ov9650cmos sensor.The paper,which is based on the hardware platform posed above,introduces the design of software system.First,the paper introduced the WinCE operating system,giving the structure of the WinCE and analysis all the stage of the system.Proposing the entire development of Wince. Completing the customize of WinCE operating system.Then,composing the camera driver based on the WinCE flow interface,analyzing the motion detect technology.Studying of the H.264encoding process based on hardware encoding unit VPU (video processing unit) of I.MX27and the stream data transimission based on RTP/RTCP.Describing the main code and implementtation of radiation monitoring software.Lastly, We do the elementary test on the system. The result of test show that the stability of the system is good.We can transmit the video fluently and get the radiation data effectively.We can say the system reach the primary demand.
