Remote data dynamic collector based on Modbus RTU communication protocol and collection method

Abstract

The invention provides a remote data dynamic collector based on a Modbus RTU communication protocol and a collection method, which relate to the field of Internet communication. The method comprises steps that 1, the collector is initialized; 2,communication is established between the collector and a cloud server, and the version information of the configuration file is uploaded to the cloud server; 3, the cloud server judges version information of the configuration file, and if the configuration file is not the latest version, the configuration file of the collector is updated; and 4, the collector periodically collects the working data of the industrial equipment according to the instruction content in the configuration file and uploads the working data to the cloud server. Dynamic datacollectionand abnormal data recovery of a Modbus RTU communication protocol can be supported, and the problem of network traffic congestion is solved.

Description

technical field [0001] The invention relates to the communication field of the Internet of Things, in particular to a remote data dynamic collection method based on the Modbus RTU communication protocol. Background technique [0002] The Modbus RTU protocol emerged in the last century and has been widely used in various industries. With the rise of the Internet of Things technology, the demand for data acquisition functions is getting higher and higher. How to adapt to the changing data requirements and the remote maintenance requirements of industrial and commercial systems has become an increasingly important topic; existing manufacturers have ModbusRTU The industrial equipment of the protocol has a set of private protocols, and the protocol data is uploaded to the cloud server. [0003] Therefore, the current remote data transmission of industrial equipment has the following disadvantages: [0004] 1. Based on Modbus TCP transparent transmission, real-time data collecti...

AI Technical Summary

Problems solved by technology

[0004] 1. Based on Modbus TCP transparent transmission, real-time data collection and data dynamic configuration can be performed, but historical data cannot be saved under abnormal network conditions, resulting in data flow; at the same time, due to the discontinuity of the Modbus address, multiple collections are required to obtain complete data , increasing communication traffic and network bandwidth congestion

[0005] 2. Based on the custom data acquisition protocol, the data can be dynamically configured. When there is a change, the firmware needs to be upgraded remotely, which increases the workload of equipment maintenance.
