基于GPRS的光发射机监控系统的设计
摘要
在有线电视网的光通信系统中,激光驱动器是光发射机的关键组成部分。它可提供足够的电流来驱动直接调制的激光二极管,或者足够的电压来驱动间接调制的电吸收。通常,激光二极管需要超过40mA的驱动电流。而调制器则需要超过2V的驱动电压来保证足够的消光比如何在高速和大信号输出的条件下来满足这些要求。因此,如何保证激光器的稳定正常工作以及及时得对光发射机出现的问题进行处理,减少损失的问题就摆在我们面前。通过对各个光发射机的总体监控,能够使我们在最少时间内发现问题,从而大大缩短处理故障的时间,达到了将损失减少到最低的程度。
本文利用无线网络通信技术,通过GPRS网络实现数据通信及监控,综合应用了单片机嵌入式系统、数据库、J2EE、网络通信和JAVA技术,从下位机到监控中心的软件进行设计并实现了光发射机的远程监控功能。
本文设计并实现了一个基于GPRS无线网络的光发射机远程监控控系统,该系统通过使用光发射机控制、GPRS通信和Internet网络中的服务器,来完成光发射机工作状态数据的监测、采集和存储。针对异常情况对光发射机进行控制。采用J2EE技术将工作数据以Web网页的形式发布,并提供了网页交互管理功能来实现对光发射机的远程监控。
经实用验证,该光发射机监控系统能正常完成本地控制台的大部分功能,并且设计新颖,工作可靠,管理方式灵活高效。其设计及实现方法对于目前光发射机监控有着积极的意义。
In cable television networks of the optical communication systems, optical laser drive is a key component of the transmitter . It can provide sufficient current to drive directly modulated laser diode, or sufficient voltage to drive the indirect modulation of the electro-absorption. Usually, laser diode requires more than 40 mA of drive current. The modulator requires more than 2 V drive voltage to ensure adequate Extinction For example, what are the high-speed and large-signal output from the conditions to meet these requirements. So, the problem is how to guarantee the stability of the normal laser and deal with the issue in the light of the transmitter and reduce losses. Through overall monitoring the various optical transmitter, we can find the source at least time, so that greatly reduce the time to deal with this problem, and reduce losses to the minimum level.
By using a wireless network communication technology, the GPRS network this paper firstly completed the data communication and control; furthermore through applicating comprehensively the single-chip microcomputer embedded systems, databases, J2EE, network communication and JAVA technology, this paper implemented the software designing from the crew to the control center and the optical Transmitter Remote Control function.
In this paper the design and realization of a wireless network based on GPRS transmitter remote-controlled closed system, which through the use of optical transmitter control, GPRS communications and Internet server in the network, to complete state data monitoring, collection and storage for the optical transmitters. Optical transmitter for abnormal control. J2EE technology will be used to work data released in the form of Web pages, and provide interactive web site management functions to achieve the optical transmitter remote monitoring.
Through practical test, the optical transmitter monitoring system can finish the normal completion of the majority of local console functions, and it' s a new layout and design, reliable, flexible and highly efficient management. Its methodology for the design and implementation of the current monitoring optical transmitter has positive significance.
