超级电容断电延时电源计算机监测系统设计

Design of computer monitoring system of super capacitor delay power supply

作为供电系统的组成部分,电源是各种系统进行正常工作的重要保证。超级电容具有存储容量大、质量轻、寿命长的特性,利用其电气特性构成的断电延时系统可以在发生断电故障或电压暂降故障时,为相应的系统提供延时电能供应,以保证系统的正常运行。为提高系统的可靠性,采用以无线传感网为核心的计算机监测系统来检测电网供电的基本情况。当出现电压不稳定、断电等情况时,由继电器接通超级电容储能元件为系统供电;当电网供电恢复正常时,由传感器所采集的储能器件中的电量等参数来决定超级电容器的工作状况,以保证系统的可靠性和安全性。

As part of the power supply system, the power supply is the important guarantee for normal work of various systems. Super capacitor has good characteristics such as great energy storage, light quality, long service life and so on. The delay system with electrical characteristics can provide delay power supply to ensure system normal operation in the event of power failure or voltage sag. In order to improve the reliability of the system, a computer monitoring system with wireless sensor network as the core was used to detect the basic situation of power grid. When the voltage was not stable or off, the super capacitor energy storage switched on relay provided power supply for the system; when the power supply was back to normal, the parameters such as power in energy storage devices collected by sensor were used to decide the operation condition of super capacitor, ensuring the reliability and security of the system.
