Embodiment Construction

[0025] A single-bus communication protocol for the interconnection of multiple node devices is to solve the problems mentioned in the background technology at low cost. Its application field is data interaction in integrated circuit chips or between chips, board-level data Multipoint communication in interactive and monitoring systems.

[0026] Since the bus rate is open, different application fields can adopt different rates. For example, high speeds can be used for interconnection of integrated circuit chips, medium speeds can be used for system board-level connections, and low speeds can be used in areas where the communication network is widely distributed. The maximum rate that a specific communication bus can achieve is determined by the bus load and bus drive capability.

[0027] Using a single signal line as a multi-point interconnection bus can improve wiring efficiency and reduce wiring and maintenance costs. As long as the data carrying medium has the ability of s...

Abstract

Said invention is unibus communication protocol for multi - node interconnected equipment,It contains adopting unique signal characteristic communication node address format and communication frame structure mode to make each communication node to be same position and capable of constituting derelict interlinkage network of communication, due to bus rate is opened so different application area can adopt different rate, Interlinkage in Integrated circuit chip can use highs speed, connection in Commission system board can use intermediate rate, slow speed can be adopted in larger distribution range field such as detecting, data acquisition, scene safety protection system etc, The highest rate reached by a specific communication bus is determined by bus load and bus driving ability.

Description

technical field [0001] The present invention relates to the technical field of communication protocols, and more specifically, to, for example, data communication between integrated circuit chips, or data communication between board levels in a system, or low-speed data communication between widely distributed data collection and monitoring nodes. letter of agreement. Background technique [0002] People have been committed to solving the information interaction between objects, and generally use wired or wireless means to connect various objects. For an electronic system, the data interaction of various integrated circuit chips can be realized by various interconnection buses between them, and such buses are generally parallel to provide high-speed data exchange. The distribution in the system is further extended to the board level, and there are also various data interactions. Sometimes these data interactions do not require a very high speed, but they are often connecte...
