STRUCTURE OF CONTROL AND MONITORING AND MANAGEMENT IEMN adapts a three-tier distribution processing architecture for monitoring and control. These are the facility management layer, the BCMS control and monitoring layer, and the ACMC control and management layer. The facility management layer is the bottom layer of the architecture for monitoring and controlling the BACnet network.展开更多

The spike voltage will introduce several undesired problems--large output voltage ripple, serious frequency noise and low efficiency. Some methods used for reducing the spike voltage are provided by the proposed expression. An equivalent lumped model is used for deducing the expression. The ACMC charge pump circuit has been designed in SILTERRA 0.18/xm CMOS process. The experiment results show that the value of the spike voltage can match the expression well. Compared with three different improved versions, the spike voltage caused by the switch-induced error voltage can be reduced obviously.展开更多
