technical field

The invention relates to a transmission management device, in particular to a transmission management device of a servo system.

Background technique

The server system (Server) provides specific services for different terminals in the network system, such as databases, file storage, printers; emails and web pages...etc., the server system (Server) in order to achieve the above-mentioned The specific service function of multiple terminals must have the ability to process the requests and messages sent by multiple terminals at the same time and respond appropriately. Therefore, in terms of hardware, in order to be able to receive multiple terminals, all necessary For the information transmitted, the server system (Server) must be equipped with multiple sets of input and output ports, and the software must be able to manage the information transmitted by multiple terminals.

Since the server system (Server) must serve the nature of multiple terminals, many independent sub-systems (Independent sub-systems) are arranged in the high-density server system (Server), but the known server system (Server) and independent sub-system The information transmission between subsystems or remote systems usually only relies on the I2C bus to transmit information and commands, but using the I2C bus to manage the entire servo system (Server) often causes problems in message delay and timeliness.

To sum up, using the I2C bus to manage the server system (Server) is too slow and the management effect is not good, so how to effectively transmit messages and commands to achieve the purpose of managing the server system (Server) remains to be resolved. technical issues.
