Based on the analysis on the concurrent processing performance requirements of monitoring system , a priority queuing algorithm is proposed to realize the concurrent scheduling of vehicle monitoring system with the algorithm implementation scheme given 在对监控中心并发处理的性能要求进行分析的基础上，提出了优先数事件队列算法来实现车辆监控中心的并发调度机制，并给出了算法实现。
An improving way is moving object detection in the front of system , and snatching a high definition picture when motion happens and then transferring back to the monitoring center . this method can settle the contradiction between definition and transferring speed 在前端对图像进行运动检测和分析,并在符合规则时抓拍高清晰度图片传回监控中心,可有效解决清晰度和传输速率间的矛盾。
Embedded terminal collects and deals with elevator information ; monitor center receives elevator status signal and sends elevator commands by communicating with embedded terminal ; filiale subsystem collects monitor requests of filiale users 嵌入式终端完成电梯信息的采集与处理；监控中心通过与嵌入式终端通讯获取电梯状态信息或控制电梯运行；分公司子系统的服务器接受分公司用户的监控请求。
The most important part of the paper is analyzing and designing of monitoring center ' s software . it particularly introduces the global structure functions and main objects of the software . at last , it explicitly expresses several crucial technical difficulties in developing it 本文的重点是对监控中心的软件进行分析设计，详细论述了软件的总体结构、功能及其主要对象，最后说明了开发软件所需解决的几项关键性技术。
The main control console takes charge of communicating with users and controlling subsystems . the gps subsystem is used for receiving and disposing gps data . the gsm / gprs subsystem is used for communicating with the monitoring and dispatching center or others 主控平台主要负责与用户进行信息交互,以便控制和管理整个车载导航系统; gps子系统用于接收和处理gps数据; gsm / gprs子系统用于和车辆监控中心或者第三方进行数据通信。
