Automatic test method for testing power and efficiency of fire-fighting power supply

Abstract

The invention relates to an automatic test method for testing power and efficiency of a fire-fighting power supply. The method comprises the steps that an industrial computer controls a programmable alternating-current variable-frequency power supply to input rated alternating current to the fire-fighting power supply; the industrial computer controls the programmable direct current electronic load to discharge in sequence according to a plurality of preset different load current values; the industrial computer acquires a plurality of output voltage values and a plurality of output current values, which are in one-to-one correspondence with the plurality of load current values, of the fire-fighting power supply; the industrial computer obtains a plurality of output power values, in one-to-one correspondence with the plurality of load current values, of the fire-fighting power supply, and obtains the output power values; the industrial computer collects a plurality of input power values, corresponding to the plurality of load current values one by one, of the fire-fighting power supply; the industrial computer obtains a plurality of efficiency values, in one-to-one correspondence with the plurality of load current values, of the fire-fighting power supply, and obtains the efficiency values; and the industrial computer is used for automatically adjusting the programmable alternating-current variable-frequency power supply, the programmable direct-current electronic load and the programmable direct-current stabilized power supply, so that the requirement on personnel is low, and the efficiency is high.

Description

[0001] This application is a divisional application of the original application with the patent application number 201910695361.5, the application date is July 30, 2019, and the invention name is a fire power supply automatic test system and method. technical field [0002] The invention relates to the technical field of fire-fighting power supplies, more specifically, to an automatic testing method for testing the power and efficiency of fire-fighting power supplies. Background technique [0003] The fire-fighting power supply is a conversion device that can convert AC power into DC power. It usually includes transformer rectification module, power management module, battery module, battery management module, working status indication module and power supply switching automatic control switch. Mains input When normal, the mains supplies power to the DC load through the fire power supply. When the mains input is abnormal, the fire power supply uses the battery management modu...

Problems solved by technology

[0004] In order to understand the performance of the fire-fighting power supply, it is necessary to test the fire-fighting power supply. However, at present, most of them manually adjust the test equipment and record the test data, which not only requires high personnel but also has a high error rate and low test efficiency.
