Abstract

The invention provides an intelligent upgrade method and system for an auxiliary control device of a hydropower station. The method comprises an upgrade step and a control step. The step of upgrade comprises the steps of S11 pre-data control units are set; S12 the pre-data control units acquire the data of an auxiliary device and a control device, and control output of the auxiliary device and the control device; S13 each pre-data control unit increases signal acquisition and output control as needed; and S14 a data control server is set. The step of control comprises the steps of S21 the pre-data control units acquire relevant data, process the data, and store or send the data to the data control server; and S22 a data control unit or the data control server processes and analyzes the acquired data to carry out control policy development and diagnosis control output. According to the invention, data acquisition, data processing, interactive application and other information upgrade are carried out on the existing auxiliary device control through the upgrade step, and through the control step, the existing auxiliary device control is upgraded from signal-based logic control to data-based intelligent control.

Description

technical field [0001] The invention relates to the field of industrial automation control, in particular to an intelligent upgrading method and system for a hydropower station auxiliary machine control device. Background technique [0002] At present, the control of the auxiliary equipment of the hydropower station is composed of a programmable logic controller (abbreviated as PLC), an analog sensor and an executive control component. Based on the logic control of the fixed process of the target value, to ensure that the pressure, liquid level and temperature of the auxiliary equipment system of the hydropower station are controlled within a certain range of the target value. [0003] The analog sensor detects the important control parameters of the auxiliary system such as pressure, liquid level and temperature, and inputs them to the control device with PLC as the core to complete the acquisition of analog and state signals, and through the predetermined control process b...
