Abstract

The invention claims an uninterruptible power source (UPS) monitoring device integrated to a communication apparatus, which comprises a central processing unit (CPU), an input / output circuit and a connection interface. The connection interface is used for providing an interface connected with a UPS power source; the input / output circuit comprises an optocoupler which is used for obtaining an alarm signal of the UPS through the connection interface, carrying out optical coupling isolation and outputting the alarm signal to the CPU, and controlling the UPS according to a control command sent by the CPU; and the CPU is shared by the communication apparatus and used for receiving and processing the alarm signal of the UPS to generate the control command and sending the control command to the output circuit. The uninterruptible power source monitoring device has favorable popularity, low cost, simple control, stability and reliability.

Description

technical field

[0001] The present invention relates to a UPS (Uninterruptible Power System, uninterruptible power supply) monitoring device, in particular to collecting various alarm signals of the UPS power supply, processing the received collection signals, and sending control signals to control the switch of the UPS power supply device. Background technique

[0002] UPS (Uninterruptible Power System, 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) , the UPS will c...
