Problems solved by technology

[0003] However, the traditional power supply control system uses a single relay to control the power supply and discharge of the circuit board, so when the relay is controlled to open and close by the power supply control method, due to the pressure difference between the relay terminals, an arc will be generated on the relay, thus Reduce the service life of the relay and reduce the stability of the power supply control system

Abstract

The invention discloses power supply control method, system and equipment and a storage medium, ad relates to the technical field of electronics. The method is applied to the power supply control system. The power supply control system comprises a first relay switch module, a second relay switch module, a control module and a to-be-measured board card. The method comprises the steps of detecting phase information of an AC input voltage signal after a power supply instruction is received by the control module, and controlling the first relay switch module to be closed if the phase information is first phase information so that a positive voltage signal in the AC input voltage signal is transmitted to the to-be-measured board card by the first relay switch module; and controlling the secondrelay switch module to be closed after the first relay switch module is controlled to be closed and if the phase information is second phase information. By the method, the technical problem that arcis generated when power is supplied to the to-be-measured board card by an existing power supply control system so as to reduce stability of the power supply control system is solved, and the technical effect of improving the stability of the power supply control system is achieved.

Description

Technical field [0001] The embodiments of the present invention relate to the field of electronic technology, and in particular to a power supply control method, system, device and storage medium. Background technique [0002] The circuit board card must be tested for power supply and discharge function after production. The test requires a power supply control system to control the power supply and discharge. In the process of using the power supply control system to test the circuit board card, the power supply control system is required to provide long-term stable and controllable discharge. [0003] However, the traditional power supply control system uses a single relay to control the power supply and discharge of the circuit board. Therefore, when the power supply control method is used to control the opening and closing of the relay, due to the pressure difference between the relay terminals, a fire arc will be generated on the relay. The service life of the relay is reduce...
