【摘要】：在信息化教育中,多媒体教学已经日益普及,而多媒体设备是教学中的关键部分,要求管理者在设备的配置、采购等方面必须进行全方位的掌控,在传统的多媒体设备管理模式中,通常采用人为笔记形式对设备的运行情况进行记录,管理者通过该记录以及个人管理经验进行下一步管理计划的制定,这种管理模式通常会因为数据记录的不完成,造成分析结果不准确,从而使多媒体设备管理模式出现静态、消息滞后等问题,在一定程度上影响了信息化教学工作的进展,所以实现对设备在线状态的实时监测显得尤为重要。本文针对多媒体设备的运行情况进行了多媒体设备在线监测与统计平台的设计,在设备状态监测中,通过设计嵌入式数据采集网关获取多媒体设备的在线状态,同时根据多媒体教室的实际情况,采用无线数据发送和有线数据传输两种方式,针对不具有无线上网条件的教室,该网关提供有线数据传输功能,同时,具有无线网条件的教室中,通过网关中的无线网络模块进行数据的传输。该嵌入式网关的主要作用是进行协议的转换,用于采用不同协议网络之间的连接工作,实现数据在网络中的传输功能,增强了该平台的兼容性。在数据预测方面,提出一种基于传统指数平滑算法的动态预测机制。该机制使用动态平滑系数对多媒体设备的使用情况进行预测,使得多媒体设备在线监测与统计平台在一定程度上能够根据数据的变化趋势进行数据追踪。和传统预测模式相比,该平台具有更高的预测精度。在数据传输方面,采用基于Socket通信方式的自定义传输协议进行设备运行状态数据包的封装与拆解,并将其运用到多媒体在线监测与统计平台的数据发送过程中。该传输协议能够很好的处理本平台在进行高频次数据发送中可能出现的粘包问题,在一定程度上提升了数据传输的可靠性。通过相关测试,本系统能够实现多媒体设备的在线监测与统计工作。
[Abstract]:In the information education, multimedia teaching has become more and more popular, and multimedia equipment is the key part of teaching, which requires managers to control all aspects of equipment configuration, procurement and so on. In the traditional multimedia equipment management mode, the operation of the equipment is usually recorded in the form of human notes, and the manager makes the next management plan through the record and personal management experience. This kind of management mode usually causes the analysis result to be inaccurate because the data record is not completed, thus causes the multimedia equipment management pattern to appear the static state, the message lag and so on, has affected the information teaching progress to a certain extent. So it is very important to realize the real-time monitoring of the equipment. In this paper, the on-line monitoring and statistics platform of multimedia equipment is designed according to the running situation of multimedia equipment. In the monitoring of equipment status, the on-line status of multimedia equipment is obtained by designing embedded data acquisition gateway. At the same time, according to the actual situation of multimedia classroom, wireless data transmission and wired data transmission are adopted. The gateway provides wired data transmission function for classrooms that do not have wireless internet access condition, at the same time, In the classroom with wireless network condition, the data is transmitted through the wireless network module in the gateway. The main function of the embedded gateway is protocol conversion, which is used to use the connection between different protocol networks to realize the transmission function of data in the network, and enhance the compatibility of the platform. In the aspect of data prediction, a dynamic prediction mechanism based on traditional exponential smoothing algorithm is proposed. The dynamic smoothing coefficient is used to predict the use of multimedia devices, which enables the online monitoring and statistical platform of multimedia devices to track the data according to the changing trend of the data to a certain extent. Compared with the traditional prediction model, the platform has higher prediction accuracy. In the aspect of data transmission, the self-defined transmission protocol based on Socket communication mode is used to encapsulate and disassemble the data packet of the device running state, and it is applied to the data transmission process of the multimedia online monitoring and statistics platform. This transport protocol can deal with the packet sticker problem which may occur in the high frequency data transmission of the platform, and to a certain extent improves the reliability of data transmission. Through the relevant tests, the system can realize the online monitoring and statistical work of multimedia equipment.
