Abnormality alarming device for UPS (Uninterruptible Power Supply)

Abstract

The invention provides an abnormality alarming device for a UPS (Uninterruptible Power Supply), wherein the UPS is connected with a current input power supply; the abnormality alarming device for the UPS comprises one or a plurality of current sensors, a temperature transmitter, a data acquisition module, a processing module, an executing module and an alarming module; the data acquisition module is connected with the current input power supply through the current sensors; the temperature transmitter is connected with the data acquisition module; the data acquisition module is connected with the processing module; the processing module is connected with the executing module; the executing module is connected with the alarming module. According to the abnormality alarming device for the UPS, a main wire inlet terminal and a standby wire inlet terminal of the UPS are respectively provided with a power supply online monitoring alarming module; when the wire inlet terminals of the UPS are de-energized, the UPS is in fault during the charging process or the temperature is abnormal, field working personnel and working personnel who are possibly not in the field are timely informed of the fault state in the form of sound-light alarm and voice call prompt, the fault is timely found out and solved, and the stability and reliability of a machine room power supply system are guaranteed.

Description

technical field [0001] The invention relates to the technical field of UPS power supply monitoring, in particular to a UPS power supply abnormal alarm device. Background technique [0002] For some important large and medium-sized computer rooms, the requirements for the stability and reliability of the power supply system are very high, so UPS will be used for centralized power supply in these applications. The UPS itself also has a status monitoring function, but it generally does not directly monitor the main and backup incoming lines provided to the UPS, which may easily lead to timely maintenance due to failure of the UPS main and standby incoming lines and charging AC terminals without alarm. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a UPS power supply abnormal alarm device, which monitors the UPS incoming line end, which is beneficial to ensure the reliability of the UPS o...
