Abstract

The invention discloses a communication method, device and system based on a system bus. The method comprises the steps of determining a data attribute of to-be-acquired data; Searching parameter datacorresponding to the data attribute in the data transmitted on the system bus; Obtaining parameter data. Therefore, when the equipment on the system needs to acquire the parameter data of certain equipment in the system, only the data transmitted on the system bus needs to be monitored, and the required data can be automatically identified and read through the data attribute, so that the logic operation requirement of the equipment can be met, plug and play is realized, and the flexibility and robustness of the system are enhanced.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, device and system based on a system bus. Background technique [0002] At present, in the local energy system, the communication system architecture is mainly based on the traditional communication architecture such as RS485, and data interaction between devices cannot be performed, but the data needs to be processed centrally by the control system. Moreover, when new equipment is added or equipment is upgraded, changes to other related equipment on the network are involved, and there are problems such as difficulty in system development and maintenance, insufficient openness, and poor scalability. [0003] Aiming at the problems of poor flexibility and scalability of the local energy system in related technologies, no effective solution has been proposed yet. Contents of the invention [0004] In order to solve the problem of poor flexibi...
