An automatic shutdown method based on detecting UPS inversion

Abstract

The invention discloses an automatic shutdown method based on detecting UPS inversion. The method comprises a step 1 that the main thread operates after power up; 2, themain thread alwaya detects theUPS state, and using the UPS inversion detection technology to obtain the current state of the UPS; 3, juding a power supply mode accord to the step 2, wherein the power supply mode is divided into anormal power supply mode and a power interruption mode; 4, judding the shutdown mode according to the step 3: A, not shutdown when the mains power input is normal, and returning to the UPS state obtained in the step 2; B, when the UPS is detect to be powered off aft the mains power is interrupted, the operating system pop up the system prompt box through the display screen to make the shutdown selection, and the operator can select the extreme shutdown or the timed shutdown. In the above manner, the invention simplifies the power-off process by detecting whether the UPS is inverted, automatically shutting down the machine and automatically executing the UPS power-off operation.

Description

technical field [0001] The invention relates to the field of self-service equipment, in particular to an automatic shutdown method based on detecting UPS inverter. Background technique [0002] UPS (Uninterruptible Power System), that is, uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply with an energy storage device and an inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC mains voltage stabilizer, and it also charges the battery inside the machine; when the mains is interrupted (accident blackout) At this time, the UPS will continue to supply 220V AC power to the load through the method of inverting the electric energy of the battery inside the machine immediately, so as to mainta...

AI Technical Summary

Problems solved by technology

In the existing self-service equipment with UPS, such as bank self-service equipment, after the bank personnel cut off the power to the self-service equipment through the power-off switch outside the equipment, the UPS will invert and supply power to the self-service equipment; if you want to completely cut off the power, you need Bank personnel manually shut down the operating system and turn on the self-service equipment to power off the UPS. The power off process is cumbersome; and in the event of an abnormal power outage, the UPS continues to supply power, resulting in a loss of UPS power
