Abstract: This paper introduces the practical design of supervision system in the parallel UPS. The supervision system can realize real-time supervision of parallel UPS in working field and meet the demand of remote monitor. The design of supervision in working field is based on DSP, CANBUS, used of ACM240128A LCM, and remote monitor is realized by RS232 communication and SNMP interface. The designs of the relational hardware illustrates the total frame, CANBUS-DSP,DSP-LCM interface circuit, remote monitor relational interface design and the design of software provides some initialization flow diagrams such as CAN based on the PeliCAN mode and LCM in this paper,etc. The supervision system is practical, stable, reliable, and costs moderately.
