The invention provides a protocol conversion configuration system based on OPC UA, and the system employs a data collection module, a memory management module and an OPC UA server module for parameterdata transmission, carries out the data transmission process management through a Driver Watch management module, and completes the format conversion of parameter data through an embedded system; wherein the OPC UA server module and the OPC UA client provide uploading of converted data and transmission of issued data. The invention also provides a protocol conversion configuration method based onthe OPC UA, which comprises the following steps: initializing the module and the equipment, acquiring data after initialization, performing format conversion on the data to obtain OPC UA format data,uploading the data by the OPC UA server module, reading the data by the OPC UA client, and uploading the data to the data monitoring and management system. According to the protocol conversion systemand method provided by the invention, a plurality of heterogeneous power devices can perform data acquisition in a unified manner, and the acquired data is output in the same format, so that management and calling are more convenient.
Description
technical field [0001] The invention relates to the technical field of power equipment operation status monitoring, in particular to an OPC UA-based protocol conversion configuration system and method. Background technique [0002] Integration and interconnection are key supports for smart manufacturing, Industry 4.0, and the Internet of Things. In the power system, the field devices of different manufacturers have different interfaces and collected data, and some even do not open the interface. Therefore, in actual use, these field devices may be an information island or difficult to be integrated into the existing system. With the use of various industrial software such as MES, the on-site data that the big data analysis of the operation of various power equipment relies on needs to be integrated into the upper-level information and management system through the on-site equipment. With the continuous update and increase of field equipment types, the requirements for integ...
