Self-adaption communication data concentrator

Abstract

The invention provides a self-adaption communication data concentrator which comprises a master control module, a port detection module and a multi-channel communication module; the master control module achieves data transmission with a UART bus through a set protocol; the multi-channel communication module is provided with a plurality of communication links, each communication link is applicableto one communication protocol, and the multi-channel communication module is used for building communication links between peripherals and the UART bus; the port detection module is used for detecting the voltage amplitude on each communication link of the multi-channel communication module and feeding back the detection result to the master control module; the master control module judges the types of the peripherals connected to the multi-channel communication module according to the detection result and calls corresponding communication protocols to perform data interaction with the peripherals. The types of the peripherals can be automatically recognized, the self-adaption communication characteristics and protocols are achieved, a large number of communication interfaces can be expanded through a single master chip, multi-channel data collection is achieved, breakpoint resume is achieved, and lost data is automatically uploaded after communication interrupt recovery.

Description

technical field [0001] The invention relates to the field of centralized data collection, in particular to a data concentrator for self-adaptive communication. Background technique [0002] In the data acquisition and analysis system, the data concentrator device is a very important link and the data interaction hub of the entire system. It is responsible for the tasks of data centralization, analysis and conversion, information preservation, and issuance of various downlink control commands. [0003] With the development of technology, the data concentrator equipment has also experienced the transformation from single-chip microcomputer, industrial computer to embedded communication management machine. Embedded data concentrators are more and more used in various monitoring systems due to their high reliability, stability, rich communication media resources and efficient software and hardware architecture. [0004] The original data concentrator follows the scheme and ide...

Problems solved by technology

[0005] The main defects of existing remote data concentrators on the market are: 1) Different connector interfaces need to be applied according to different signals. The flexibility is poor and the development cycle is long; 2) and this kind of data concentrator needs to be configured by the debugger before it can work. After converting the device port and protocol, there are often factors of heavy workload and unreliability, and the communication management machine After the damage, the replacement of a new communication management machine still needs professional configuration to work
