Description

Technical Field

[0001] The present invention relates to the technical field of UPS power supply status monitoring, and specifically to a UPS power supply status monitoring and early warning system. Background Art

[0002] An uninterruptible power supply (referred to as UPS power supply) is a constant voltage and constant frequency uninterruptible power supply containing an energy storage device and mainly composed of an inverter. It is mainly used to provide uninterrupted power supply for a single computer, a computer network system or other power electronic devices. When the mains input is normal, the UPS power supply stabilizes the mains voltage and supplies it to the load. At this time, the UPS is an AC mains voltage stabilizer, and at the same time it also charges the battery inside the machine; when the mains power is interrupted (accident power outage), the UPS power supply immediately converts the electrical energy of the battery inside the machine into 220V alternating current through inversion and continues to supply it to the load, so that the load can maintain normal operation and protect the software and hardware of the load from damage;

[0058] The non - electrical data acquisition module includes an appearance acquisition unit and a fan speed acquisition unit. The appearance acquisition unit is used to acquire the data on the outer surface of the UPS power supply, and the fan speed acquisition unit is used to acquire the fan speed of the UPS power supply.

If there are flaws on the surface of the UPS power supply shell or internal components, such as abrasions, corrosion, or other defects, it will affect heat dissipation, resulting in uneven heat dissipation, possibly causing temperature rise and increasing the risk of faults;

[0061] The specific expression for the fan speed acquisition unit to acquire the fan speed of the UPS power supply is as follows:

[0062]

[0063] Among them, max t [FSZS] represents the maximum speed in the fan speed FSZS set in the t - th sampling period. This measurement can be carried out using a Hall sensor or an infrared tachometer to avoid mechanical contact interfering with the fan operation;

[0064] The status analysis module includes an electrical analysis unit and a non - electrical analysis unit.

If no warning is given, it terminates and waits for the next sampling period;

[0068] The non-electrical analysis unit comprehensively analyzes and calculates based on all the data in the non-electrical data acquisition module and the first influence coefficient to obtain the specific expression of the second influence coefficient as follows:

DEYXXS represents the second influence coefficient, FSZS 0 represents the initial fan speed. Increasing the fan speed will bring additional power consumption, and the fan efficiency is also affected. If the fan speed is too low, it may lead to overheating and increased risks. Usually, the fan speed is fixed. When the fan speed drops, the dust accumulation on the surface of the fan seriously affects heat dissipation.

[0071] When the monitoring and early warning module determines that the first influence coefficient or the second influence coefficient needs early warning, it sends early warning and dispatching information to the staff. When the monitoring and early warning module receives the first influence coefficient DYYXXS, it judges it. When the first influence coefficient DYYXXS exceeds the first risk threshold DYFX, it sends early warning and dispatching information to the staff. When the first influence coefficient DYYXXS does not exceed the first risk threshold DYFX, no early warning is given, and the first influence coefficient DYYXXS is sent to the non-electrical analysis unit. When the second influence coefficient DEYXXS exceeds the second risk threshold DEFX, the monitoring and early warning module sends early warning and dispatching information to the staff. When the second influence coefficient DEYXXS does not exceed the second risk threshold DEFX, no early warning is given. For the dispatching of the staff, dispatching algorithms can be used to determine the specific dispatching personnel, including the A* algorithm, the shortest distance algorithm, and the priority algorithm, etc.;

[0072] In addition, the setting of the size of the threshold in the present invention is for the convenience of comparison. Regarding the size of the threshold, it depends on the amount of sample data and the base number set by those skilled in the art for each group of sample data; as long as the proportional relationship between the parameter and the quantified value is not affected, it can be determined by those skilled in the art according to each sample data and multiple rounds of experimental processes.
