The invention discloses a board card, computer equipment and a power-off control method and device for the board card. The board card comprises a substrate, and a pulling assisting device, a touch switch and a controller are installed on the substrate; the substrate is also provided with a voltage conversion module and a communication module. When the board card needs to be pulled out of the inserted computer mainboard, the pulling assisting device is used for enabling the light touch switch to be closed after being manually jacked, and after the light touch switch is closed, a disconnection signal is sent to the controller; after receiving the disconnection signal, the controller sends a signal reset instruction to the communication module; after receiving the signal reset instruction, the communication module sends a communication stop message to other board cards inserted into the computer mainboard; after receiving the disconnection signal, the controller sends a power-off instruction to the voltage conversion module; and after receiving the power-off instruction, the voltage conversion module stops supplying power to the load of the board card. By adopting the scheme, the influence on the stability of the system when the board card inserted into the computer mainboard is pulled out in an electrified manner is reduced.
Description
technical field [0001] The present application relates to the field of board card technology in the field of computer technology, and in particular to a board card, computer equipment, a power-off control method and device for a board card. Background technique [0002] The board card is a printed circuit board, referred to as PCB (Printed Circuit Board, printed circuit board) board, which is produced with connectors, which can be inserted into the slot of the computer motherboard to control the operation of the hardware. The functions of the board can be developed based on the needs of practical applications. [0003] At present, in practical applications, in order to ensure the uninterrupted, continuous and stable operation of the application system, it may be necessary to deploy multiple boards with the same function, some of which are used for backup. For example, board A and board B are mutual backups. When board A fails and the application system isolates board A, boa...
