Equipment power supply reliability detection device and detection method thereof

Abstract

The invention relates to an equipment power supply reliability detection device and detection method thereof. The device comprises a power supply circuit, a main control circuit, a power supply control circuit, an acquisition circuit and a communication circuit. The power supply control circuit is used for controlling power-on and power-off of a tested equipment power supply; the acquisition circuit is used for acquiring the working current of the tested equipment power supply; the communication circuit is used for receiving a data frame sent by a tested equipment power supply; the main control circuit is used for acquiring a power supply detection strategy, a current detection strategy and a communication detection strategy, judging whether the acquired power supply detection state parameter value conforms to a power supply detection strategy or not, if so, judging whether the acquired working current conforms to a current detection strategy or not, if not, judging whether the data frame received by the communication circuit conforms to a communication detection strategy or not, if so, judging that the reliability reaches the standard, and if not, judging that the reliability doesnot reach the standard. According to the invention, real-time and accurate reliability test can be carried out according to the power-on and power-off characteristics of various tested equipment power supplies, and the power supply reliability of the equipment power supplies is improved.

Description

technical field [0001] The invention relates to the field of power supply product detection, in particular to a device power supply reliability detection device and a detection method thereof. Background technique [0002] At present, the power supply quality problems of various power supply products are relatively prominent. The power supply products put into the market have problems after customers use them for a period of time. Among them, power supply problems account for a considerable proportion. This situation occurs in different products, and the types of power supply problems that occur are relatively Therefore, in the process of research and development and production of various products, it is necessary to carry out reliability testing of equipment power supplies. [0003] The current power detection devices on the market mainly use the cut-off and close functions of the power supply to artificially judge the operating status of the equipment under test, so as to ...

AI Technical Summary

Problems solved by technology

[0004] 1. Single detection method

The power-on and power-off times of various types of equipment under test are inconsistent, and it is impossible to carry out the corresponding strategy test according to the power-on and power-off characteristics of the power supply of the equipment under test, and the versatility is poor

[0005] 2. Poor real-time performance

No detection strategy is set, it cannot run automatically, and it cannot judge the operating status of the device under test during the real-time detection process

[0006] 3. Poor accuracy

Artificial judgment of the operating status of the equipment under test requires human participation, which increases the possibility of judgment errors
