For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the invention will be further described, can not be used for limiting the scope of the invention.It should be noted that when not conflicting, the embodiment in the application and the various modes in embodiment can be mutually combined.
Referring to Fig. 1, the embodiment of the present invention proposes a kind of method realizing hot plug process, including:
Step 100, controller judge that pluggable module is extracted from ordinary connector, stop the business relevant to pluggable module.
In this step, pluggable module can be from serial communication transceiver.
In this step, controller is judged that pluggable module is extracted from ordinary connector and is included:
Controller judges that the level of the default pin of described ordinary connector is become high level from low level.s
In this step, specifically how to stop the business relevant to pluggable module and the technology of knowing of those skilled in the art can be adopted to realize, the protection domain being not intended to limit the present invention, repeat no more here.
In this step, controller can run two operating systems simultaneously, including non-real time operating system and real time operating system.Based on real time operating system, this step can judge whether pluggable module extracts from ordinary connector, and stop the business relevant to pluggable module based on real time operating system.
Optionally, the method also includes:
After step 101, controller stop the business relevant to pluggable module, pluggable module is unloaded.
In this step, how pluggable module unloading specifically can be adopted the technology of knowing of those skilled in the art to realize by controller, and the protection domain being not intended to limit the present invention repeats no more here.
Pluggable module can be unloaded by this step based on non-real time operating system.
The method also includes:
Controller judges that pluggable module is inserted into ordinary connector, and pluggable module is carried out initial configuration.
Wherein, controller judges that pluggable module is inserted into ordinary connector and includes:
Controller judges that the level of the default pin of described ordinary connector is become low level from high level.
Wherein it is possible to pluggable module is carried out initial configuration based on non-real time operating system.
