Design And Implementation Of Environment Monitoring For Earth Station Communication Room Based On PLC

In the information age,most communication devices use high integrated design,and use a large number of precise electronic devices.The communication equipment room has high integration,precision equipment,large number of equipment,high calorific value,high temperature,humidity and air cleanliness.The environment of the machine room is an important condition to ensure the stable operation of the equipment.Therefore,it is very important to build an environmental monitoring system with comprehensive monitoring,accurate control,easy maintenance and outstanding benefit to ensure the environment meet requirements of the communication machine room,and play an important role in the stable operation of the satellite earth station communication system and the improvement of the maintenance efficiency.Based on the PLC programmable controller technology,with the help of various sensors and control mechanisms,through the MCGS configuration software and Ethernet network,the real-time monitoring and accurate control of temperature,humidity,air cleanliness and indoor pressure are realized.This system is mainly controlled by power supply and programming.Devices,sensors,computer networks,and business display and control clients are made up of several parts.After the construction of the environmental monitoring system is completed and put into use,it realizes the accurate control and real-time monitoring of the environment of the communication machine room,further guarantees the environmental quality of the communication machine room,improves the stability of the communication equipment operation,optimizes the level of the management and maintenance of the technical operation and maintenance of the unit,and promotes and guarantees the public satellite broadcasting and television public.The normal and reliable operation of the service system.The system design and construction work mainly include the following aspects:(1)combing the special equipment environment requirements of the earth station communication machine room,checking the environmental parameters that need to be monitored and controlled,according to the actual work and operation and maintenance,setting the control target and all kinds of threshold value for the corresponding technical parameters,so as to ensure the stability of the environment of the star communication machine room and ensure the establishment of the environment.Stable work to ensure safe transmission work.(2)according to the key technical parameters and control requirements,the research and selection of the mature motor,PLC controller,motor frequency converter,electronic control mechanism and sensor on the market are carried out.(3)combining the actual working environment to determine the overall control framework and function,without affecting the normal operation and maintenance work and not causing adverse impact on the environment of the communication machine room,the hardware systems such as installation of sensors,motor,electronic control mechanism,control box,upper computer,network equipment,etc.are deployed on the basis of the working environment in the field.(4)according to the PLC programmable controller development technology,configuration software and corresponding computer technology,the previous collection of environmental data is analyzed and controlled,and the control mechanism of the system is formulated and designed and the software program is written.(5)the actual operating environment monitoring system,according to the monitoring,control,maintenance convenience and energy saving effect,to optimize and adjust the hardware,software design and technical parameters,gradually improve and improve the functions of the environmental monitoring system,and verify the stability and reliability of the environment monitoring system,and find out.The problem is solved in time.(6)develop a scientific and secure user access control strategy according to the personnel composition and actual situation of the earth station communication room environment maintenance.
