DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to raw material transfer control in a raw material yard, and more particularly, to a raw material yard facility for transferring raw materials from a raw material yard to a raw material tank of a lower-stage factory and entering the raw material tank. The present invention relates to transport control for performing a plurality of transport operations concurrently while sharing.

[0002]

2. Description of the Related Art Conventionally, an operator selects a system and simulates a scheduled transfer preparation for a transfer control in a raw material yard, or calculates a transport amount and a timing by a computer simulation, and schedules in advance. A method has been adopted in which a transfer job JOB schedule is created, and the scheduled transfer work is controlled and executed in a fixed order until the scheduled amount or the scheduled end time is reached. Note that the transfer job JOB is defined as a series of work units that transfer a single brand of a given amount in one system.

[0003] This conventional, scheduled transfer work JOB schedule (system, transport amount, start / end time) is created in advance by simulation calculation, and control of the transfer work is performed in that order (transfer work interference management of control is performed by a lower control device). Method), the actual raw material yard equipment has many variations in transport time, and there are many equipment troubles.
The control result does not follow the scheduled time schedule, so the optimal transport amount also changes from the time of schedule creation,
In some cases, mobile units and belt conveyors (B
C), the transportation efficiency is reduced, the scheduled transport work must be reviewed every time, the computer processing load is increased,
There is a problem that the operator has to confirm a new schedule each time, and since the control computer does not manage the transfer work interference, flexible transfer control such as a plucking process according to the actual results cannot be performed. The plucking is a switching operation from a branch point of the BC system. Regarding the raw material yard transfer control, various automatic control methods have been proposed. For example, Japanese Patent Application Laid-Open No. 3-243508 discloses an automatic control method based on a yard plan based on a knowledge base. Japanese Patent Application Laid-Open No. 4-89708 discloses that a transfer efficiency of an ore yard based on a knowledge base is maximized. Japanese Patent Application Laid-Open No. 4-89709 discloses an automatic control method that maximizes the transport efficiency of a coal yard based on a knowledge base. An automatic control system for a coal yard based on the raw material inventory simulation described above, and Japanese Patent Application Laid-Open No. 3-279124 discloses a method for resolving conflicts in transport work centering on yard planning.

[0004]

In the conventional method, an operator or a control computer uses a scheduled transfer operation JO.
Although the B schedule is fixedly set in advance in the transport system control device, in a raw material facility in which mobile units and BCs are shared between the transport systems, the scheduled transport job JOB is performed.
If the schedule and the actual work end time deviate from each other, the work schedule already set in the system controller will not be optimal in terms of transfer efficiency, and even if the control computer reschedules in real time, the control computer Since the work interference management during control execution is entrusted to the transfer system controller, the set scheduled transfer work JOB cannot be modified, and a time lag of at least one work occurs. Error occurs. In order to eliminate this error, the optimum transport system must be selected again, which increases the computer load and the monitoring load of the operator.

SUMMARY OF THE INVENTION It is an object of the present invention to avoid the interference of the transfer equipment, to increase the transfer efficiency including the plucking operation as much as possible, and to reduce the monitoring load of the operator as much as possible.

[0006]

According to the present invention, in a raw material transfer control in which a plurality of transfer systems share a mobile unit and a BC and a plurality of transfer operations are performed simultaneously in parallel, the control computer uses a plurality of schedules in advance. Just enter multiple start and end points of the transfer work or check the result of automatic selection of the start and end points. While performing work interference management during transfer control, the priority transfer work is determined in real time, the optimum transfer system is selected, and the target transfer amount is calculated.

[0007] The material transfer control system of the material yard equipment of the present invention for realizing this is provided with transfer request information of an operator.
As the input means A incorporate advance a plurality of conveying the original starting point equipment name and transport destination endpoint device name of planned transport material; captured by the input means A, conveying the original origin apparatus name and
Based on the destination end device name , the scheduled transfer work JOB information for each starting point and each system is input to the input source starting device name.
And means for calculating a plurality worth of transport destination endpoint device name B; incorporated in said input means C; input means D capturing equipment failure current state data; input means C capturing transport task performance event data of the mobile station and transport system , Mobile equipment and transport systems
Based on the transfer work actual event data , work interference management, priority work determination, next work start determination, target transfer amount recalculation, stop determination, and plucking determination are performed for the currently-executed transfer work JOB and the scheduled transfer work JOB. Work start, work stop, plucking command and stock
Means E for outputting a measurement command output to the mobile device and the transport system controller in real time; and means F for controlling the mobile device and the transport system.

[0008]

In this material transport control system, a mobile unit and a BC are shared between a plurality of transport systems, and a plurality of transport operations are performed simultaneously in parallel, resulting in a variation in raw material transport time, and work interference between the transport systems. When the system is applied to a raw material yard facility where the occurrence of occurrences or the inter-operation packing is possible, the start and end points of a plurality of scheduled transportation operations can be input to the control computer in advance or completely automatically, Oversight of the actual results and schedule of the work, and while performing work interference management of the transfer work during the transfer control and the planned transfer work, judge the priority transfer work in real time, select the optimal transfer system, and set the target transfer amount. Calculate, automatically determine the execution transfer job JOB, and output the command so that the transfer efficiency including the plucking work can be maximized, avoiding the interference of the transfer equipment. Performs automatic transfer control in real time based on the command.

[0009]

Next, an embodiment of the present invention for an ore yard will be described. FIG. 1 shows a system configuration of this embodiment. In FIG. 1, reference numeral 100 denotes a material yard process control computer (raw material process control), 400 denotes an input / output CRT terminal device having an I / F (interface) between the raw material process control and an operator, and 105 denotes a CRT input / output. This is an input / output processing function for controlling, and the operator can input or start the starting point / end point (operator-requested transport information) of the material to be transported or check the transport work schedule via the CRT terminal device 400. it can.

Reference numeral 300 is a block diagram of a group of on-site equipment in a raw material yard, 310 is a group of mobile units (accepting and dispensing machines), 320 is a group of conveyors, shuttles and trippers, 33
0 indicates a weighing machine group. Reference numeral 200 denotes a lower-level controller for controlling the on-site equipment, which controls the on-site equipment 300 and manages the operation results and the current state. The controller device includes a mobile device control PC (programmable controller) 210 for controlling the mobile device group and a conveyor control PC 220 for controlling the conveyor group. The on-site equipment control lower-level controller 200 transmits the transfer work / weighing result information and the equipment operation / failure information to the raw material process controller 100 in real time. The raw material processing computer 100 receives and inputs the relevant information in the performance collection / editing process 150, and the operation status 14
The transfer work result, the yard current state, and the tank current state information are stored in the data file as 0, and the equipment operation current state and the equipment failure current state are stored as the equipment current state 145 in the data file.

The transport work scheduler function 120 and the transport work monitor / command function 130, which are the core functions, are based on the above-mentioned operator-requested transport information 110 from the operator or the required transport information 115 automatically created from the tank status. The work scheduler function 120 creates a plurality of pieces of transfer work schedule information 125 for each starting point and each system according to the equipment specifications.
From the information of the transfer work schedule 125, the operation status 140 and the equipment status 145, and the real-time start-up operation event, the results and schedules of a plurality of transfer operations are overlooked, and the work interference management 135 during transfer control is performed. Automatically determines the priority transport work in real time, selects the optimal transport system, calculates the target transport amount, avoids interference with transport equipment, and maximizes transport efficiency including plucking work automatically. A job execution execution job is determined, and a system-specific transfer control command based on the relevant information is output in real time to the on-site equipment device control lower-level controller 200.
The OB is displayed on the CRT terminal device 400.

The on-site equipment control controller 200 performs transport control based on this system-specific transport work execution job and an automatic transport control command, and transmits the transport work result information to the raw material process controller 100. In raw material process control 100,
The next transfer work schedule 125 and transfer work execution JOB are calculated, determined or determined in real time by the transfer work scheduler function 120 and the transfer work monitor / command function 130 based on the corresponding transfer work result information, and the transfer control command for each system is provided. The lower-level controller 20 for on-site crisis control
The automatic transport control is performed by repeating the cycle of transmitting the signal to 0 and setting the control output.

Next, the transfer work scheduler function 120 and the transfer work monitor / command function 130 of the raw material process controller 100 are performed.
The details of the processing will be described. FIG. 2, FIG. 3 and FIG.
2 shows an example of input / output data of each process. FIG. 2 shows the operator requested transfer information 110 or the requested transfer information 115 of FIG.
FIG. 3 is an outline of the process of the transfer work scheduler function, and FIG. 4 is a diagram showing the transfer work schedule which becomes I / F data with the transfer work monitor / command function output by the transfer work scheduler function. Configuration and data items.

As shown in FIG. 2, the requested transport information is configured for each of the starting devices of the transport operation. Normally, only the starting device and the end device or the end yard information are sufficient.
If you want to specify the C system and the transportation amount, you have the corresponding items so that they can be reflected. Specifically, as shown in FIG. 3, the berth receiving / transporting operation (from the unloader to the ore yard), the sieving tank (from the yard to the sizing plant), and the soaking ore loading (from the yard or the sizing plant product tank to the ore relay) Soaking yard with soaking via tank), Soaking sintering tank (from soaking yard to sintering plant), Plain sintering tank (from yard to sintering plant), Sinter ore blast furnace (from sintering plant) (Blast furnace factory), the starting point and the end point are different for each transfer operation, and data specified as the start point and the end point for each transfer operation is defined.

Based on the minimum required transfer information, the transfer operation scheduler function automatically sets a transfer system (a unit of a series of BC groups for transferring materials in a facility from the starting point to the end point) as shown in FIG. The transport work schedule information is created for each starting point by selecting from the equipment constant table and calculating the transport amount from the stock empty amount at the tank destination.

FIG. 4 shows an example of the configuration of the transport work schedule. Here, as the level of the transport work schedule JOB, J0, J1, J2, J3,... Jm (m is 7 to 8)
By introducing the concept of (degree), it is possible to centrally execute the transfer work schedule creation and the real-time transfer work control command in the control computer. J0 is during suspension (output of the transportation system suspension / instruction command after completion of the starting point to completion of suspension),
J1 is during conveyance (start operation from starting operation to output of a stop / pause command after stopping the starting position), and J2 is during preparation (output of preparation command to start position to B
Start operation after starting the C system) and J3 to Jm are scheduled 1
To (m-2), J0, J1, and J2 are transfer work jobs under control set in the lower-level controller for on-site equipment control, and J3 to Jm are transfer work schedules that can be updated by the transfer work scheduler. It is.

The transport work monitor / command function 13 shown in FIG.
0 indicates that the J3 to Jm for each starting point created by the transfer work scheduler function 120, when a raw material yard transfer result event has occurred, the J3 transfer work schedule JOB of all the starting points is overlooked, and all transfer controls are being executed. Priority transfer work is determined in real time, the optimal transfer system is selected, the target transfer amount is calculated, the J3 JOB at the start point of the relevant system is shifted to J2 JOB, and at the same time the schedule after J4 is performed. Are shifted up by one, and a start command for the starting point is output to the J2 JOB system. Alternatively, depending on the transfer result event, if the starting operation is started, J2 JOB is changed to J1 JOB.
To J1 if it is the starting stop after the starting stop command.
The job is shifted to J0 JOB and a stop / stop command is output to the BC transport system.

Next, the process of the transport work monitor / command function 130 will be described with reference to a flowchart, and the core method of work interference management and priority work determination will be described. FIG. 5 shows a transport operation monitor / command function 130.
5 is a flowchart showing the processing contents of FIG. Each item of the process of the transport operation monitor / command function 130 will be described below. The activation factor analysis processing 51 is activated for each starting point for every transport operation result event of all operations in the raw material yard, and the subsequent processing content branches for each event factor. If the event factor has occurred, the process proceeds to the work interference process 20, and if the event has ended, the process proceeds to the ongoing work synchronization 54.

In the work interference management process 53, the current state of the actual operation of the transport equipment is managed. In the next running work synchronization processing 54, if a transfer work other than the transfer work JOB created by the control computer (a transfer work without JOB) is being performed, the JO of the schedule 1 (J3) input later is executed.
B is synchronized, a process for starting the control computer mode operation is performed, and J3 job is shifted to J1 job in job management.

In the plucking check processing 55, the plucking relationship between the JOB being transported (J1) and the JOB of schedule 1 (J3) is determined and marked on the J3 JOB.

In the priority judging process 56, a priority judgment is made between JOBs (J3 of different origins) which exist side by side for each origin and between JOBs (J3 to Jm) within the same origin. The relationship with the transfer operation without JOB is also considered. The determination result is used in the subsequent stop / placking processing 58 or the next JOB start processing 59 for the determination.

In the control command processing for each factor 57, as a separate process corresponding to each event factor, the job is shifted and each command is output.

In the stop / placking process 58, all factors are determined for the J1 JOB during conveyance, and a stop determination or a plucking execution determination with the next JOB is performed. For example, if the end tank is full and there is a next job that can be plucked, plucking is performed, and if not, stop is performed.

In the next job start processing 59, schedule 1 (J
It is determined whether or not the job of 3) can be started. If the job can be started, each preparation command is output, and the job is being prepared (J
The process proceeds to 2) (corresponding to the starting point preparation command event at the output of the control command 57 for each factor). The difference from the above stop / placking processing 58 is that a single JO that does not perform plucking
B has the function of shifting to preparation (J2).

In the target transfer amount calculation processing 60, the target transfer amount is calculated from the stock amount of the transfer destination and the position of the conveyor scale with respect to the conveyor scale used by the JOB newly prepared (J2) or transferred (J1). Calculate the amount. J at the same time
The calculation of the scheduled end time of the OB is also performed.

In the plucking preparatory process 61, the job of the transport (J1) and the job of the schedule 1 (J3) are the same type of plucking (the transport source starting point and the raw material brand are the same, the transport destination end point is different, and the transport operation is continued. When plucking is necessary, the J3 JCB preparatory preparation process is performed.

Transport work monitor / command function 130 (FIG. 1)
Is a process 51 of an event for each starting point as shown in the flow of FIG.
~ 58, and finally 54 ~ 56-59 ~ 6
By performing the processing of No. 1, it is possible to make a priority determination between the same starting jobs.

Next, the contents of the work interference management processing 53 shown in FIG. 5 will be described in detail. The work interference management is the interference management of the equipment used in the transport work after all, and can be divided into a start point, a BC system, and an end point. For these, the following five terms are used to perform work interference management. Here, the concept of “use reservation” is introduced for J2 JOB in order to perform more detailed management by the control computer than before.

(1) Hard reserve: the corresponding equipment is actually being used; (therefore, if the equipment is shared between the transfer systems, the transfer system other than the work cannot be executed.) (2) Hard mask: other (3) Schedule reserve: Reserved use of the relevant equipment; (4) Schedule mask: Other transport systems are in use. The use reservation is in progress, the equipment is shared with the relevant transport system equipment, and the equipment cannot be used due to competitive interference; (5) Paused: The suspended (old) system of the plucking system; a specific example with reference to FIG. Will be described. FIG. 6 is a schematic example of a transport system with shared facilities, which includes two of A and B as starting points (for example, a reclaimer) and three of 1, 2, and 3 as end points (for example, an entry shuttle). As the BC system, A1 (A-1), A2 (A-2), B1 (B
1), B2 (B-2) and B3 (B-3) are considered. In this case, the equipment interference relationship between the BC systems is fixed, and if at least one location shares a BC, a competitive interference relationship is established.

[0030]

[Table 1]

In this example, the interference management method will be specifically described in the case of performing the same type of plucking operation from the A1 system to the A2 system.

First, for the A1 system, the control computer is A1
A preparation command is output to the system start point, A1 enters a use reservation state, and becomes a schedule reserve (hereinafter, SR). At the same time, the A2, B1 and B2 systems that have an interference relationship with A1 become a schedule mask (hereinafter, SM), and in this state, the interference management is performed so that these systems cannot be executed already. Next, the control computer outputs a start command to the A1 system, the BC system is started, and in a state where the starting point is in operation, the A1 system shifts to transporting (J1), and at the same time, hard reserve (hereinafter referred to as “J1”). HR). At the same time, the A2, B1 and B2 systems that have an interference relationship with A1 similarly to SR become hard masks (hereinafter HM).

Next, a case is considered in which the same type of plucking is performed on the A2 system after the A1 system is conveyed by a predetermined target conveyance amount. In this case, the control computer outputs a plucking command to the A2 system, so that the A2 system is being transported (J1) and the A1 system is being suspended (J0). When the A2 system is in the process of being transported, it becomes HR, and A
The 1, B1 and B2 systems become HM.

Next, when the suspension of the A1 system is completed (J0 disappearance), the use of the facilities as the A1 system is terminated, and the suspension is canceled. At the same time, it is necessary to release the HM of the system masked during the suspension of the A1 system. Since HM is applied from a plurality of systems redundantly, for each of A2, B1 and B2 in the interference constant of the A1 system, reference is made to the state of each interference-related system, and when all BC systems are not in HR or in suspension. Release HM. In this case, the HM of the A2 system is released, but the HM cannot be released because B1 and B2 are masked by A2. Table 2 shows the above processing.

[0035]

[Table 2]

Next, the contents of the priority judgment processing 56 shown in FIG. 5 will be described in detail. The priority determination process 56 is performed with respect to the next scheduled 1 (J3 JOB) of the start point when the start event ends the transporting job (attains the target transport amount).
FIG. 7 shows the contents. This is a process that cannot be realized by the control by the lower-level controller for controlling the on-site equipment, which has been conventionally performed, and is first enabled by the control computer.
In this process (FIG. 7), the manual work check 71 and the start time designation check 72 determine only the J3 JOB to be determined, and the following processes 73 to 79 are executed for the BC system which may interfere with the J3 JOB. J0, J1, J2, J
3 Judge for all jobs. Note that the processes 73 to 79 are processing examples covering the transport work that can be generally performed in the raw material yard of the iron and steel industry. The processing not to be performed is fixed. Regarding the flowchart of FIG. 7, the following check is performed in each processing block, and if the check applies, the corresponding J3
For the job, the priority is determined to be large or small.

In the manual work check processing 71, the corresponding J3

In the ongoing work check process 73, whether the corresponding starting point is J0 or J2 (small priority), the corresponding starting point is J1 and the device configuration is different from the corresponding J3JOB (small priority), or the BC system of the corresponding J3 JOB Check if there is no interference (low priority). Otherwise, the process proceeds to the next process (74).

In the plucking work check processing 74,

In the work priority designation check process 75, the priority designation can be arbitrarily set for each work, and whether or not the J3 JOB has a schedule interference (low priority) is determined.
Whether the corresponding J3JOB has no schedule interference and the priority designation is larger than the partner origination JOB (next), or the partner origination J3 has a priority designation larger than the corresponding J3JOB and the partner origination JOB (J0-J
Check if 2) is not high priority (next) or any other (low priority). When the determination of “(priority small)” is not established, the process proceeds to the next process (76). Hereinafter, the state of proceeding to the next process is described as (next) in the sentence.

In the simple stock amount check processing 76, the corresponding J
3 If both the JOB and the opponent's origin JOB are plain tanks, perform this if the relevant J3 JOB has a schedule interference and the opponent's origin JOB is in the process of being stopped (next), or the J3 JOB has no schedule interference and the inventory level is higher than the opponent's origin JOB Is lower (next), whether the corresponding J3 JOB has no schedule interference and the inventory level is higher than the partner starting JOB, and the other party is not high priority (next) or other (low priority).

In the ore-loading achievement check process 76, the process is performed when both the target J3 JOB and the partner starting point JOB are in the soaking tank, and whether the target J3 JOB has no schedule interference and the loading achievement is lower than the partner ( Next), whether the corresponding J3 JOB has no schedule interference and the stowage achievement degree is higher than the other starting JOB and the priority is not large (next), whether the other J3 JOB has schedule interference and the other JOB is in the process of being stopped (next),

Finally, if all the checks (71 to 79) fail to make a judgment, the corresponding J3 JOB is set to (high priority) (80, 81). If the above-mentioned large priority or small priority can be determined for each process, it is determined as a decision judgment (82),
If the determination cannot be made, the process is performed by repeating the flow of checking the next block.

Finally, the transfer work monitor / command function 130 of the control computer 100 is controlled by the lower controllers 155, 20.
An example of a command to be output to 0 will be described. As described above, in the present invention, the control computer 100 outputs a control command in real time to the start point / end point / BC system each time. In the example of the raw material transporting equipment in the raw material yard of the steel industry, the unloader is used as the starting point. , Reclaimer, stack reclaimer, blending reclaimer, hopper under blast furnace,
There are soot loading CFW (quantitative cutting device), sintering factory, sizing factory exit side starting point, etc. The end points are stacker, blending stacker, blending hopper, blast furnace tank tripper, sintering tank tripper, coal tank tripper, There is a sizing plant original ore tank tripper and the like.

The transport work monitor / command function 130 outputs a preparation command, a start command or a stop command to the starting point / end point of the mobile equipment, and outputs a start command or a stop command to the feeders. A set command or a sounding stock measurement command is output to the shuttle trippers, and a selection command, a deselection command, a start command, a plucking command, a payoff command or a cancel command is output to the BC system. FIG. 8 shows the output timing of these control commands and the timing of input of the performance information from the lower controller 200 to the control computer 100.

In this manner, the transfer control system shown in FIG. 1 enables automatic transfer control of the raw material yard.

[0050]

As described above, with regard to the transport control in the raw material yard equipment for iron ore or coal, the mobile equipment and the BC are shared between the multiple transport systems, and the raw material transport in which the multiple transport operations are performed simultaneously in parallel. In the control, the following effects can be obtained.

(1) Each time a transfer work event occurs, the results and schedule of a plurality of transfer works are looked down in a cross-sectional view, and while performing work interference management during the execution of transfer control, priority transfer work is judged and controlled in real time. By issuing the command, finer control can be performed.

(2) Each time a transfer work event occurs, a transfer work schedule is selected in order to calculate the target transfer amount by selecting an optimum transfer system that maximizes transfer efficiency, including plucking work, while avoiding interference with transfer equipment.
