Abstract: |
The article introduces an application of the super capacitor as a back-up power supply for the elevator flat layer’s emergency device in our daily life. Super capacitor is used for the back-up power in the automatic relief devices in that it is of low cost, environmentally-friendly, with long service life, easily maintained and of high rescue efficiency and so on. At the same time, with the demonstration of the model elevator, it also introduces how to control the model elevator, how to choose the type of super capacitor, super capacitor charging and discharging circuit and the elevator power failure detection. Likewise, it elaborates on the hardware circuit and software flow diagram respectively. At last, the paper also shows the inverter process using super capacitor for back-up power in the real elevator and gives the related calculation of inverter process and the super capacitor group selection, which are based on the model elevator.
