Abstract

The invention relates to an access method of Modbus equipment. The access method comprises the following steps that configuration files comprising data configuration information and protocol configuration information are preset; an intelligent equipment gathering dynamic library reads and analyzes the configuration files, and the data configuration information obtained through analysis of the configuration files is stored in internal variables of the intelligent equipment gathering dynamic library; and when the Modbus equipment is accessed, the data configuration information is extracted from the internal variables of the intelligent equipment gathering dynamic library according to operation commands to communicate with the Modbus equipment. The invention further provides an access system of the Modbus equipment. The access method and the access system of the Modbus equipment can reduce development workload, and reduce 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...
