In step S1, shown in Fig. 2, several power modules are connected to a CAN.Specifically, power module 1, power module 2 to power module N are connected in CAN by CAN communication EBI, under common communication protocol, it is achieved the communication data exchange between each power module.
In step S2, shown in Fig. 3, its own sequence information frame is uploaded to CAN by several power modules.Its own sequence information frame data are packed by each power module, and self unique its own sequence information frame (including module information and serial number) is uploaded in timing, and is uploaded in CAN by CAN protocol.When arriving power module timed sending time, its sequence number information frame uploads in bus；When not arriving power module timed sending time, enter waiting state, until timed sending time arrives next time.As selection, this timed sending time is time regulatable, can be modified setting according to the specific requirement of system.Preferably, the sequence number information frame of CAN agreement is as shown in the table:
| BYTE | Data name |
| 1 | Company-information |
| 2 | Product type |
| 3-4 | Date of manufacture |
| 5-6 | Produce numbering |
| 7-8 | Retain |
Wherein, sequence number information frame herein includes eight bytes, and the first byte is company-information, and the second byte is product type, and the 3rd is the date of manufacture to nybble, and the 5th to the 6th byte is for producing numbering, and the 7th to the 8th byte is reserve bytes.Preferably, the sequence number information frame of its own sequence information frame with other described power modules of storage is ranked up, as power module, the foundation that compares by the numbering that produces of the 5th to the 6th byte.As selection, it is also possible to using overall for sequence number information frame as sort by, or other have distinctive partly as sort by.
In step S3, shown in Fig. 4, each power module receives the sequence number information frame of all power modules the sequence number information frame of other power modules that storage is except self CAN.Wherein, each power module can real-time reception from the message of CAN, and identify whether the sequence number information frame for other power modules, if it is by judging whether it is the sequence number information frame of legal serial number and overlap, preserve correct sequence number information frame, judge for Self address.Preferably, the sequence number information frame of other power modules is stored in the serial number memory block of therein by each power module.As selection, it is also possible to the sequence number information frame of other power modules is kept at therein.It is to be appreciated that serial number memory block can be located in the memory element in power module, its capacity can be adjusted according to system specific requirement, but at least should enough store the sequence number information frame of every other power module.As selection, the sequence number information frame of self is also intended to storage, and it is stored in when dispatching from the factory inside power module, is available for calling at any time.It is to be appreciated that the sequence number information frame of self and the sequence number information frame of other power modules be not in identical position storage.
