Problems solved by technology

However, the battery has a lifespan, and the actual capacity of the battery when it is fully charged will also decrease with the increase of the battery usage time, and if the battery is in a long-term charging state, such as a long-term stable function of the mains, the UPS will It will not be started to supply power to the battery, but will be in the working state of supplying the mains voltage to the load after being stabilized, that is, the UPS power supply will only be charged without discharging for a long time, which will further accelerate the damage of the battery

Embodiment 1

[0030] refer to figure 1 , a UPS power supply monitoring method in an ICU room, comprising the steps of:

[0031] S1. Record the number of times m that the UPS passively uses the UPS battery to charge and discharge due to the mains power interruption, and the number n of the times that the UPS uses the UPS battery to charge and discharge the UPS battery because there is no mains power interruption within 7 days or 10 days;

[0032] S2. Obtain the total charge and discharge times k=m+n of the UPS battery according to the passive charge and discharge times m and the active charge and discharge times n of the UPS battery obtained in step S1;

[0033] S3. Obtain the battery capacity Q of the UPS battery according to the total charge and discharge times k of the UPS battery, and the mapping relationship between the battery capacity of the UPS battery and the number of charge and discharge times;

[0034] S4. When the mains power supply is powered by the UPS battery, monitor the re...

Embodiment 2

[0038] refer to figure 2 ,

[0039] A UPS power supply monitoring device in an ICU room, including a passive charging and discharging counting module, an active charging and discharging control module, a microprocessor, a voltage monitoring unit, a power monitoring unit, an external database, and a warning unit; module, active charge and discharge control module, voltage monitoring unit, power monitoring unit, external database, and warning unit connection; among them,

[0040] The passive discharge counting module is used to monitor and record the number of times m that the UPS passively uses the UPS battery for power supply due to the interruption of the mains power, and send the obtained number of times m to the microprocessor;

[0041] The active charge and discharge control module is used to control the UPS power supply to actively use the battery for power supply when the UPS power supply does not have a mains power interruption within a certain period of time, and mon...

Abstract

The invention relates to method for monitoring an UPS (Uninterruptible Power System) of an ICU (Intensive Care Unit) room, which is characterized in that the number m of times that the UPS passively uses a UPS storage battery for charging and discharging due to mains supply interruption and the number n of times that the UPS artificially and actively uses the UPS storage battery for charging and discharging due to the fact that mains supply interruption does not happen within a certain period of time are recorded in real time, the actual battery capacity of the UPS storage battery can be accurately estimated, and a reference is provided for subsequent reliable power supply of the UPS storage battery; and meanwhile, the working voltage U of the UPS storage battery and the total working power P of the electric equipment of the ICU room are obtained through real-time monitoring, so that the calculation accuracy of the backup delay time t of the UPS can be ensured, the residual electric quantity of the power supply can be prompted in time, and the situation that power supply of the UPS is suddenly interrupted is avoided.

Description

technical field [0001] The invention relates to the technical field of UPS power supply monitoring, in particular to a method and device for monitoring UPS power supply in an ICU room. Background technique [0002] ICU is Intensive Care Unit (Intensive Care Unit), which is a dedicated intensive care unit that provides isolation places and targeted monitoring for critically ill or comatose patients. The equipment in the ICU room includes ventilators, ECG monitors, defibrillators, sputum suction machines, blood gas analyzers, advanced nursing beds, etc. These devices need to work 24 hours a day, that is, they need 24-hour uninterrupted power supply. Therefore, the current ICU room is equipped with a dedicated UPS power supply. [0003] UPS (Uninterruptible Power System) power supply, that is, uninterruptible power supply, is a constant voltage and constant frequency uninterruptible power supply containing energy storage devices and inverters as the main component. It is mainl...
