Substrate management master unit receives the control information that management system is sent, and according to numbered transmission data message, if
It is substrate management master unit, is then forwarded directly to main arm processor, main arm processor is distinguished according to the control information received
The message for being converted to keyboard or mouse is sent to USB interface, and corresponding server receives corresponding informance, completes data communication.
Subelement is managed if substrate, then it is single to counterpart substrate management to send control information for substrate management master unit
Member, corresponding substrate management subelement parsing control information be sent to sub- arm processor, and sub- arm processor is according to receiving
Control information is respectively converted into keyboard or the message of mouse is sent to USB interface, and corresponding server receives corresponding informance, completes number
According to communications.
Keyboard and mouse infomational message is divided into two kinds：Control message and data message, the data frame of a CAN can include
The data of 8 bytes can be at most carried, so data message length is 8 bytes.Control message format as follows：
Wherein, Class is type of message 00：Represent configuration message.DNID：Represent which BC module selected.Range of choice
For 0-31.Ecc is check bit.RESERVE is reserved bit.Keyboard and mouse infomational message form is as follows：
Wherein, Class is type of message 01：Represent keyboard；10 represent mouse.
Message is type of message：Specific peripheral hardware action type is represented, message type table signal different according to Class
Justice is also different.Such as 0001 space bar is represented under Keyboard Message, left mouse button is represented under mouse information.Ecc is check bit.
DATA0,1 represents the data that message carries.Under mouse type, coordinate parameters are represented.Under Keyboard Message, represent
A variety of key combinations.RESERVE is reserved bit.
It is as follows that the transmission of video information is referred to as uplink workflow：
Accessed server substrate administrative unit, the ARM processing of master unit and substrate management subelement is managed comprising substrate
Device receives video information, manages master unit if accessed unit is substrate, substrate management master unit directly obtains information.
If accessed is substrate management subelement, video information is sent into substrate by high-speed bus manages main list
Member, substrate management master unit receive CAN information, are converted to the network information and are sent to management system.
Uplink message is only a kind of comprising data message, as follows：
Wherein, Class is type of message 11：Represent uplink data messages.
STATE is transmission state：Wherein 00 represents to start to send upstream data, and 01 represents complete 6 byte datas, 11 tables
Show the end of transmission.
DATA represents the data that message carries.In the case where STATE is 00,01, DATA represents all 6 byte datas；11
Under state, DATA [7:0] byte number that this message carries is represented, at most carries 5 bytes.
RESERVE is reserved bit.Ecc is check bit.
BMC management frameworks based on CAN are solved in the existing long-distance management system based on BMC chip, are existed
Need increase extras the problem of could supporting the remote management of a large amount of servers, and favorable expandability；And remotely visit
Ask that multiple servers only need to access the IP address of substrate management master unit, additional multiple substrate management subelements achieve that.
