【摘要】 通信电源在通信工作中占有极为重要的地位。通信电源一旦发生故障必将造成通信中断。实行通信电源集中监控，是保证现代化的通信设备正常运转的有效途径。 本课题研究的即是移动基站中动力环境监控模块的实现，这样的局站为数很多，因此降低监控模块的成本是关键。本设计依据低成本、高可靠性的原则，所完成的工作下： （1）采用开发环境比较成熟，价格更便宜单片机为监控器的核心，监控器主体只用一个AT89C52，没有外扩RAM、ROM，使可靠性大大提高。单片机的I/O接口芯片全部采用最新的串行工作方式接口芯片，与传统的并行接口芯片相比，它们引脚数少，体积小，占用的口资源少，因此用AT89C52的4个8位的I/O口就完成了多个通道的数据采集、控制、键盘、显示和报警等功能，没有扩展其它I/O接口，使系统接线简化，可靠性提高。 （2）单片机的开发使用C-51语言。C-51语言是一种结构化程序设计语言，它兼顾了多种高级语言的特点，并具备汇编语言的功能，用C语言编写软件，可以大大缩短开发周期提高效率，并且增加程序的可读性，便于改进和扩充，从而研制出规模更大，性能更完备的系统。 本设计根据基站的实际情况来选取关键的监控点，既全面反映了设备的运行情况，又避免了系统的复杂化。整个设计中始终强调实用性、可靠性，监控器结构紧凑，通用性强，有很好的推广应用前景。更多还原

【Abstract】 Power supply of communication plays an important role in communication service. Once power supply of communication break down, the whole comunication device will break immediately. Concentrated monitoring is an effective way of ensuring modem communication device nm properly.My subject study in the realization of dynamic environment supervision module in movable stations mainly. Such stations can be seen here and there. Therefore, the key problem is to decrease the cost of monitoring module. My subject is designed on basis of lower cost and higher reliability. It has finished the following job:1)In my design microprocessor which develop environment maturely is the focus of the monitor and AT89C52 is the subject of the monitor. It doesn抰 extend RAM and ROM, increasing the reliability largely. Microprocessor 憇 I/O interface chip is the latest serial interface chip. Comparing with the traditional parallel interface chips, they have fewer legs~ smaller volume and use fewer resources. Therefore, multiple channel data selecting controls keyboar&. display and alarm are realized through AT89C52抯 four eight-bit I/O interface, without extending other I/O interface ,making the system simplified and reliability increased.2)C5 1 language is used to develop microprocessor. It is a structural program design language, which not only has many advanced languages?character but also owns assembly language抯 function. Compiling software with C languagecan decrease development cycle greatly and increase the efficiency and readability of program, which is convenient to improve and extend in order to develop bigger scale and better capability system.My design selects key monitor point in tenn of actual situation in the station, which reflect appliance抯 running condition and avoid the complication of the system. My design emphasizes on realization and reliability all the time. Monitor抯 structure is compact and its application scope is wide. That is , it will have wonderful prospect in the future.更多还原
