Abstract

The invention relates to a method for accessing Modbus devices, comprising the following steps: presetting configuration files containing data configuration information and protocol configuration information; intelligent devices collect dynamic libraries to read and parse the configuration files, and analyze the configuration files to obtain data configuration information Stored in the internal variables of the smart device collection dynamic library; when the Modbus device is connected, extract the data configuration information from the internal variables of the smart device collection dynamic library according to the operation instructions, and communicate with the Modbus device. The invention also provides an access system of Modbus equipment. The invention can reduce the development workload and reduce the complexity of code maintenance.

Description

technical field [0001] The invention relates to the field of power environment monitoring, in particular to a Modbus device access method and system. Background technique [0002] A basic function of power environment monitoring is to access various smart devices in a protocol manner and implement management functions on this basis. The Modbus protocol is a device access protocol widely used in the industrial field, and access to devices based on the Modbus protocol has also become a common requirement for power environment monitoring systems. [0003] The current mainstream method is to develop a collection dynamic library for each specific device, implement Modbus protocol analysis through this dynamic library, and send the analyzed data to the upper system through the internal interface of the monitoring system. This method requires the development of a dynamic library for each device, which requires a large development workload and complicated code maintenance. Conten...
