Design And Implementation Of Digital Embedded Power Monitoring System

As the heart of modern engineering equipment,power supply continuously provides power for equipment and plays an irreplaceable role in communication system.With the rapid development of electronic technology,the functions of electronic equipment are more abundant and the structure is more complex.In the existing communication automation system,in order to facilitate the real-time monitoring of the communication automation equipment running state,most of the remote monitoring system is adopted,and the automatic monitoring of power supply system also has a certain space for improvement.In terms of manpower and cost,The traditional power monitoring scheme in terms of manpower and cost can not meet the needs of today’s equipment,and there are differences in local demand,power system and communication equipment between the response is slow and many other drawbacks and engineering problems.Therefore,it is necessary to design a remote power on-line monitoring system for the embedded AC/DC power supply system to realize digital control and ensure safe operation.Embedded power system development has been carried out in China for many years,there are relatively reliable framework and solutions,but also some can be optimized and improved,mainly reflected in data processing and receiving reliability,battery energy saving and software upgrade.The main work and innovative design of this thesis are as follows:(1)The storage of performance alarms and other parameters adopts fixed data blocks for storage,and each quantity is allocated its required data length respectively.The idea of class hash table is used to encode the stored values,which is convenient for data access and classification and archiving.In order to reduce the probability of false alarm and improve the reliability of the system operation,a deep filtering method is designed for the acquisition level of alarm parameters by masking.(2)The charging and discharging characteristics of lead-acid battery were analyzed,and the floating charging switching mode and current limiting management were designed according to the protocol.a cycle sleep energy saving system of rectifier module was designed in order to save energy and improve efficiency.On the basis of improving system efficiency and saving energy,the service life of rectifier module was extended to the maximum extent.(3)Through the Dual Bank mode arrangement of the Flash in MCU application,the independent Boot Loader and the Bank Swap mode can be switched while software upgrade.It not only solves the problem that the equipment needs to stop to carry out the software upgrade during the use process,but also ensures that the development and debugging work will not be affected under the condition that the amount of code exceeds the limit during the development period.
