A multi-protocol communication management machine

Abstract

The invention discloses a multi-protocol communication manager. The multi-protocol communication manager is characterized in that a processing unit is in communication with measure-control devices through that a multi-serial port controller is connected with a plurality of downstream serial port converting units. At the same time, the processing unit is connected with an ethernet controller and an upstream serial port converting unit to achieve communication with an upper computer. The processing unit is connected with a controller area network (CAN) controller and a magnetic random access memory (MRAM). Due to the adoption of the structure, the multi-protocol communication manager has the advantages that various communication protocols are supported, various interfaces are supplied, communication interconnection of different measure-control equipment and the manager is achieved, information collection on a whole electricity transformer and distribution automatic system is achieved and is intensively sent to local backstage supporters or faraway scheduling master stations, meanwhile, commands of the backstage supporters or the master stations are transmitted to the measure-control devices, so that local or remote control is achieved.

Description

technical field [0001] The invention relates to the application of industrial automation, in particular to a multi-protocol communication management machine. Background technique [0002] In distributed industrial automation applications, due to the distribution of communication data of on-site measurement and control devices, and the inconsistency of their communication protocols, each measurement and control device needs to be managed by a specific host computer, which does not use the centralization of monitoring develop. [0003] As a network intermediate device, the current communication management machine has the characteristics of the upper computer for the measurement and control device, and the characteristics of the lower computer for the background monitoring system, but the communication protocol it adapts to is limited, and it cannot communicate with all the measurement and control devices. [0004] In view of the above problems, it is a problem to be solved in...
