Fig. 2 shows the principle framework of an embodiment of the automatic dock stockyard handling facilities analogue system of the present invention.
Fig. 2 is referred to, the analogue system of the present embodiment includes：Stacker emulator, reclaimer emulator, user management module.Preferably
, in addition to system journal module.
The function of stacker emulator simulation stockyard stacker device control module (ACCS).Stacker emulator is also referred to as
SMS stacker emulators.Stacker simulation apparatus are standby to receive stacker upper strata operation work order information, and work order data are split into tool
The executable request command of body, and request command is sent to by bottom hardware according to user's request and performed, and pass through vector
Drawing instrument performs fed back real time data information according to stacker bottom hardware and draws stacker dynamic analog figure.
The function of reclaimer emulator simulation stockyard reclaimer device control module (ACCS).Reclaimer emulator is also referred to as
RMS reclaimer emulators.Reclaimer emulator receives reclaimer upper strata operation work order information, and work order data are split into specifically
Executable request command, and request command is sent to by bottom hardware according to user's request and performed, and pass through vector plotting
Instrument performs fed back real time data information according to reclaimer bottom hardware and draws reclaimer dynamic analog figure.
Above-mentioned stacker emulator and reclaimer emulator include the emulator internal structure shown in earlier figures 1,
This is repeated no more.
User management module is verified whether user has and uses windrow to being managed using the user profile of analogue system
The authority of machine emulator or reclaimer emulator.
System journal module is recorded to the running situation and user's operation data of analogue system and is stored in relation number
According in storehouse, facilitating user to be concluded, analyzed to problem data and handled.
Emulator in analogue system needs to operate on installation JVM common computer or server, and requires to pacify
The relational database for data storage is filled, and the long-range opc server link address of offer and OPC correspond to stockyard automation and set
Standby data integration address.
The emulator of automatic dock stockyard handling facilities analogue system performs flow as shown in figure 3, being emulated with reclaimer
Illustrated exemplified by device.
In step sl, user enters reclaimer Simulation Interface, and interface can be given birth in a browser according to current user information
Into server push address, while the method for pushing of addresses match is generated and pushed in Web server, for follow-up reclaimer certainly
Dynamicization data real time propelling movement provides basis.
In step s 2, emulator creates a plurality of concurrent prison according to reclaimer work order data address and request instruction type
Thread is controlled, to monitor data acquisition and control field in opc server corresponding to feeding machine equipment, and it is different using JEasyOPC
The mode that step is read reads data in opc server in Web server in real time, and judges whether monitoring data changes, if monitoring
Data change, then are pushed to Simulation Interface in time.
In step s3, judge whether reclaimer monitoring function is opened, step S4 is entered if opening and carries out work order data
Checking, monitoring function of otherwise dishing out are opened exception and returned in step S2.
In step s 4, judge whether feeding machine equipment receives work order data, if receiving work order data, enter step
Rapid S5 performs request instruction operation, otherwise into step S6, continues waiting for work order data message.
In step s 5, the reclaimer work order data of reception are split, generates different instruction request operations, and root
Demand is emulated according to user, by JEasyOPC synchronization WriteModes write request command information into opc server, if write-in is abnormal
Then throw exception prompt message.
In the step s 7, judge whether reclaimer request instruction has returned data after the completion of performing, if there is returned data, say
Bright reclaimer hardware normally performs request instruction and completes automation mechanized operation, and caused data message renewal during reclaimer is operated
Into opc server, can be captured if change occurs for monitoring data in opc server by the monitoring thread in step S2, monitoring
Thread is by the data real time propelling movement of change to reclaimer Simulation Interface.Otherwise, illustrate feeding machine equipment be not carried out request instruction or
Perform error.
In step s 8, reclaimer Simulation Interface draws vector graphics, including bulk goods according to Web server end propelling data
Stockyard basic data figure, feeding machine equipment current operating conditions and history run track etc., and proportion switch operation is provided, make
Figure shows become apparent from.
In step s 9, after reclaimer completes a simulation operations, whether user can close prison according to oneself demand estimation
Function is controlled, if closing monitoring function, all monitoring threads opened is closed in step S2, discharges thread pool thread, improve
Emulator operational efficiency.
In step slo, after user completes whole simulation operations, Simulation Interface, Simulation Interface and Web server meeting are exited
It is automatic to close in step S1 the push function opened.
