Abstract

The embodiment of the invention provides a hot plug control device and method, the device comprises a pluggable module, a control module, a control circuit and a power circuit, the control circuit and the power circuit are connected in series in an output loop of the control module; the pluggable module is provided with a signal pin and a power supply pin, the signal pin is a short-time pin, and the power supply pin is a long-time pin; the pluggable module is connected with the control module through the signal pin and the power supply pin; the control module is used for sending out a system signal according to the pull-out or insertion of the pluggable module; the control circuit is used for receiving the system signal sent by the control module and controlling the power circuit to be disconnected or connected according to the system signal; the invention further discloses a hot plug control method, in the hot plug process, the pluggable module is powered off in advance, and therefore the zero-current hot plug function of the pluggable module is simply and effectively achieved.

Description

technical field [0001] The embodiments of the present invention relate to, but are not limited to, the technical field of hot-plug processing, and specifically, relate to, but are not limited to, a hot-plug control device and method. Background technique [0002] At present, in the high-power modular control module, the module parallel technology is basically used, and the output power of the control module is increased by the parallel connection of the power modules. In order to further improve the reliability and rapid maintainability of the control module, if one of the power supply modules in the power supply system fails or needs to be upgraded to the software, it is necessary to insert or unplug one of the power supply modules when the entire control module is powered off. The power module can be replaced without affecting the normal operation of the control module, and the rapid replacement of the replaceable power module is realized, which requires the replaceable po...
