【摘要】：随着手持GPS设备的普及，GPS技术在方便我们日常出行的同时，GPS设备上记录的历史轨迹数据也可以作为公安机关威慑犯罪的重要线索和证据。但是，由于GPS软件种类繁多，其依赖的硬件设备和软件环境差异很大，很多GPS设备使用专有的格式储存历史轨迹数据，互相之间无法通用查看历史轨迹，这为公安机关的物证鉴定工作增加了巨大的时间和经济成本。因此，经由“2012年公安部应用创新计划项目”立项，由吉林省公安厅承担，，东北师范大学软件研究所主持开发的GPS轨迹提取云服务平台应运而生。通过对公安机关提出的问题进行分析，以及在研发过程中发现的问题，本文提出的GPS轨迹提取云服务平台设计成了四个模块：显示模块、控制模块、虚拟机模块和基于Auto Hotkey的自动化操作模块。前台的显示模块通过http实现和服务器端的控制模块之间的通信，控制模块首先根据用户选择的硬件型号开启相应的虚拟机模块，其次通过接口调用自动化操作模块在虚拟机上进行不同的操作，最后读取虚拟机的操作结果并发送给显示模块显示。通过以上方案能够实现对用户屏蔽不同GPS设备的操作差异，从而减少用户学习不同设备操作的时间，降低购买不同设备的成本。GPS轨迹提取云服务平台在研发的过程中在吉林省公安厅日常案件中进行了试应用，基本实现了基于云服务的对于不同GPS设备历史轨迹提供相同的提取操作，取得了一定的效果。
[Abstract]:With the popularity of hand-held GPS devices, GPS technology not only facilitates our daily travel, but also the historical track data recorded on GPS devices can be used as an important clue and evidence for public security organs to deter crimes. However, because of the wide variety of GPS software, the hardware devices and software environment are very different. Many GPS devices use proprietary format to store the historical track data, so they can not view the historical track in general. This adds huge time and economic costs to the identification of physical evidence in public security organs. Therefore, the GPS track extraction cloud service platform was developed by Jilin Provincial Public Security Bureau and developed by the Software Research Institute of Northeast normal University through the Project of "2012 Ministry of Public Security Application Innovation Plan". Through the analysis of the problems raised by the public security organs and the problems found in the course of research and development, the GPS track extraction cloud service platform proposed in this paper is designed into four modules: display module, control module, Virtual machine module and automatic operation module based on Auto Hotkey. The display module of the foreground realizes the communication between the control module of the server and the control module of the server through http. The control module first opens the corresponding virtual machine module according to the hardware model selected by the user. Secondly, the automatic operation module is called through the interface to perform different operations on the virtual machine. Finally, the result of the operation of the virtual machine is read and sent to the display module to display. The operation differences of different GPS devices can be shielded from the users through the above scheme, thus reducing the time for users to learn the operation of different devices. Reducing the cost of purchasing different equipment. The GPS track extraction cloud service platform was tested in the daily cases of Jilin Public Security Bureau in the process of development. The cloud-based service provides the same extraction operation for different GPS device track, and obtains certain results.
