智慧路灯远程监控平台的设计与实现

摘要

为实现城市路灯的实时监控,及时了解照明设备是否正常运转,达到系统智能、节能等目的,设计并实现了基于服务器集群的路灯远程监控管理软件.与传统的监控方式相比,易于扩展并且能够处理高并发访问请求,有效避免访问量过大而导致过载问题.通过Nginx 分别将HTTP请求和TCP通信连接分发给集群中的服务器,提高了服务器在高负载情况下的工作效率.使用Redis作为关系型数据库的缓存数据库,将Session容器中的全局变量保存在Redis中,实现Session的同步和共享,保证了数据的一致性.测试结果表明系统通信稳定、界面友好,使用Nginx负载均衡大大提升了系统的性能,同时便于未来的系统扩展.%Remote monitoring and management software based on server cluster is designed and implemented to achieve system intelligence and energy conservation,which by realizing the real-time monitoring of urban street lamp and observing whether the lightning facilities are in good condition.Comparing with the traditional monitoring methods, the proposed method is easy to extend and has the ability of dealing with high concurrent access requests,which effectively avoids overload problems caused by excessive access.The HTTP requests and TCP communication connections are respectively distributed by Nginx to the servers in the cluster,which improves the efficiency of the server under high load conditions.Redis is used as the cache database of relational database,and the global variables in Session container are stored in Redis to achieve the synchronization and share of Session for purpose of ensuing the consistency of data.The experimental results show that this system is stable in communication,friendly in interface,and using Nginx to balance load not only greatly improves the performance of the system,but also facilitates future system expansion.
