Problems solved by technology

[0004] At present, in the existing power monitoring training simulation system, the remote control locking function of the equipment is generally realized through the logical judgment of the scene configuration file or the hard-coded background program, but this method lacks flexibility, and it is very likely to Involves source code changes, and will increase considerable configuration workload in engineering applications

Abstract

The invention relates to an electrical equipment remote control locking characteristic simulation method based on LUA scripts. An operator triggers a remote control simulation operation of the electrical equipment on a system HMI interface. A system real-time library detects a remote control simulation event and submits the event to a data engine at the bottom layer of the real-time library. The data engine then submits the remote control point information to an LUA script engine. The LUA script engine retrieves the LUA script rule of the remote control point in a rule base and finds out a signal point that the electrical equipment is required to be associated with in a configured association point XML input file. The LUA script engine obtains the real-time value of the relevant signal points from the real-time library through the data engine and calculates the logical result of the rule according to the rule. If the result is 1, the remote control characteristic of the electrical equipment is satisfied and the remote control is performed normally. Otherwise, it does not meet the remote control characteristics of the electrical equipment, the current remote control is rejected. The result whether to meet the remote control locking characteristic is written in the real-time library by the data engine, and is ultimately fed to the system HMI interface.
