Description

Technical field [0001] The present invention relates to the field of communication, in particular to a communication address allocation method, a communication network connection device, and a bus access device. Background technique [0002] Once the communication node in the existing communication network is damaged, it is often unable to quickly disconnect the connection with the network cable. Instead, the user or maintenance personnel will be reminded to repair the network when the network communication failure is detected by the network failure detection equipment. , It is easy to cause network failure and even hardware damage. Therefore, there is an urgent need for a bus access device and a communication network connection device that can disconnect the communication node from the network connection line when the communication node is damaged. [0003] Address allocation is the basis of any information exchange. The address allocation rules of the terminal determine the addre...

Problems solved by technology

However, both static configuration and dynamic allocation have their own disadvantages

Specifically, the static address configuration needs to write the address artificially or in advance, which makes the configuration process a huge workload or significantly increases the production cost before the system is put into operation. The operation of the address is complicated; if the conventional dynamic allocation method encounters a node failure, the corresponding relationship between the address and the terminal is prone to change, which makes it difficult for some applications that require a complete one-to-one correspondence between the address and the physical node and require automatic allocation. accomplish
