Description
technical field [0001] The present invention relates to the technical field of generalized connection of bus architecture, in particular to a generalized connection device and connection method based on bus architecture. Background technique [0002] At present, the cables based on the bus architecture usually come in two forms: series connection form and three-way connection form. The serial connection is a hand-in-hand connection between terminals, which is simple, reliable, and easy to implement. It is more suitable for situations where there are few interconnected devices and the locations are relatively concentrated. The three-way connection form is more flexible than the above-mentioned series connection form. The connection between the terminal node and the bus is connected in the form of a three-way connection, and then connected to the terminal equipment and the bus through three cables. This method is more applicable when there are many interconnected devices and ...
