UPS接口转换卡的设计与实现

Design and Implementation of Interface Transition Card for UPS

针对目前大多数UPS监控系统因采用串行接口监控方式,而导致的传输距离受限制,不能实现任意距离的分散式远程监控的问题,提出了一种基于SNMP网络管理协议的UPS监控系统的设计方案,设计了集成SNMP协议的硬件接口转换卡。采用了带有SNMP协议的μC linux操作系统,完成了串行接口到网络接口的数据转换,实现了在SNMP协议下的UPS网络管理和监控。

Most UPS monitoring systems monitor the UPS by the serial interface,but this way is limited by transmission distance of the interface,so the monitoring system also cannot work in a long distance.To solve the problem,a monitoring system based on SNMP network management protocol is introduced.The design of hardware interface transition card which is integrated with SNMP protocol is proposed.The μClinux operating system is used with SNMP protocol,has completed the data conversion from serial interface to network interface,and has achieved the network management and monitoring of UPS with SNMP protocol.
