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.

2) according to logical expression result of calculation value；
3) end value (0 is locking, and 1 is not locking) is written in real-time database on the attribute of corresponding points.
Because LUA script files exist independently of real-time database, call without direct interface between real-time data base, it is impossible to
Complete the access to real-time database, it is therefore desirable to self-defined LUA functions, and by data engine and real-time bank interface.More than two
Individual function-point method, it is only necessary to which definition reads real-time database, writes two interfaces of real-time database, and function declaration is as follows.
DATA READ_OMS(UINT OBID,STRING ATTRNAME)；
BOOL WRITE_OMS(UINT OBID,STRING ATTRNAME,DATA RET)；
The real-time database object of present procedure operation is obtained by singleton pattern inside READ_OMS, WRITE_OMS function
G_OMSDATABASE, and the read-write operation to real-time database is completed by the object.

What is stated is a kind of " two from three " logic rules conventional in breaker, i.e., three breakers have at most only been allowed in the same time
Two breakers that is, in each combined floodgate breaker, first judge whether two other breaker is closing a floodgate in closing position
Position, if then not allowing to close a floodgate (closing locking), if not then allowing close a floodgate (not locking of closing a floodgate)；And for separating brake remote control life
Make then unaffected, never locking.This kind of logic rules be widely used in bus switch and two inlet wire disconnect switchs it
Between locking emulation.
In the urban track traffic Training Simulation System that our company develops, on each circuit fault simulation is provided with
Point, when the emulation of over-zone feeding romote controlled locking is carried out, the remote signalling variable being related to up to 34, therefore the logic rules of reality are remote
It is more complicated than example.
Fig. 3 is the typical LUA rule scripts schematic diagram of the present embodiment.
