【摘要】：近年来,随着我国进入社会、经济转型期,服刑人员数量逐渐增多,监狱面临服刑人员数量大、管理难,时有发生越狱脱逃等情况。因此,本文设计了基于S3C6410的手持监视终端设备,狱警使用该设备实现对服刑人员的监视和管理。手持监视终端是基于S3C6410应用处理器设计的,具有ZigBee通信、GPS定位、3G通信、摄像、实时图像传输等功能。通过ZigBee通信功能读取服刑人员腕表信息,利用信号指示强度测量狱警和服刑人员之间的距离,保证狱警对服刑人员近距离的监视管理,利用GPS定位功能实现定位,利用3G通信功能从后台管理中心获取服刑人员实时信息,实现对指定服刑人员的监视,利用实时传输协议RTP协议可将现场图像信息传输至后台管理中心。本文实现手持监视终端的硬件设计、系统移植和软件设计。硬件设计上,以S3C6410为核心处理器设计了DDR动态存储器、NandFlash、3G通信模块、基于CC2430的ZigBee通信模块、GPS定位模块、LCD显示和Camera摄像头模块等硬件电路。系统移植方面,为手持设备移植了Bootloader和Linux操作系统,为本设备构建了文件系统。软件设计方面,实现3G模块上网程序移植、RTP协议库-JRTPLIB库的移植,实现基于JRTPLIB库的图像传输、ZigBee通信和GPS定位数据解析的程序设计。最后,成功完成了手持监视设备的硬件测试、Linux系统测试和软件测试。经测试,本设备软硬件工作正常、稳定可靠。
[Abstract]:In recent years, with China entering into the society, economic transformation, the number of prisoners gradually increased, prison faced with a large number of prisoners, difficult to manage, escape from prison from time to time and so on. Therefore, this paper designs a handheld monitoring terminal device based on S3C6410, which is used by prison guards to monitor and manage prisoners. The handheld monitoring terminal is designed based on S3C6410 application processor. It has the functions of ZigBee communication, GPS positioning, 3G communication, camera, real-time image transmission and so on. Read the watch information of the prisoners through the ZigBee communication function, measure the distance between the prison guards and the prisoners by means of the signal indicating strength, ensure the warden's close supervision and management of the prisoners, and use the GPS positioning function to realize the positioning. The 3G communication function is used to obtain the real-time information of the prisoners from the background management center to monitor the designated prisoners. The real-time transmission protocol RTP is used to transmit the field image information to the background management center. In this paper, the hardware design, system transplantation and software design of handheld monitoring terminal are realized. In the hardware design, DDR dynamic memory, NandFlash,3G communication module, ZigBee communication module based on CC2430, GPS positioning module, LCD display and Camera camera module are designed with S3C6410 as the core processor. In the aspect of system migration, Bootloader and Linux operating system are transplanted for handheld devices, and file system is built for this device. In the aspect of software design, the transplantation of 3G module online program, RTP protocol library-JRTPLIB library, image transmission based on JRTPLIB library, ZigBee communication and GPS positioning data analysis are realized. Finally, the hardware test, Linux system test and software test of handheld monitoring equipment are successfully completed. The test shows that the hardware and software of the equipment are working normally, and it is stable and reliable.
