多媒體設(shè)備在線監(jiān)測與統(tǒng)計平臺
[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.
