  Hereinafter, an automatic operation stop cause providing apparatus and method according to an embodiment of the present invention will be described with reference to the drawings. The automatic operation stop cause providing apparatus and the method thereof according to this embodiment are used in, for example, a coke oven facility shown in FIG. The coke oven facility 1 includes a plurality of furnace groups in which a plurality of carbonization chambers 2 are arranged in a straight line. The coke oven facility 1 is provided with various mobile devices used for operation. As the moving machine, a coal car 3 charging raw coal into the coke oven facility 1, an extruder 4 for extruding red hot coke from the coke oven facility 1, and red hot coke extruded from the coke oven facility 1 by the extruder 4 are extinguished. There is a guide car 5 that guides the car 6 and a fire extinguisher 6 that conveys red coke to the fire extinguishing equipment 7. A plurality of these mobile machines are provided for each coke oven facility 1. In this example, a total of three coal loaded cars 3, three extruders 4, three guide cars 5, and five fire extinguishers 6. There are 14 mobile units. Further, a rail dedicated to each mobile unit is laid in a straight line along the coke oven facility 1 around the coke oven facility 1. Each mobile device is driven by a dedicated on-board device (not shown) so as to move and be arranged on each rail and perform a series of operations in cooperation.

  In this embodiment, a part of operation by the charcoal vehicle 3 will be described as an example of these mobile devices. Various apparatuses are provided in the coal loading vehicle 3 in order to charge coal into the carbonization chamber 2 of the coke oven facility 1. FIG. 2 is an explanatory diagram of the dust-proof hood 8 provided in the charcoal vehicle 3. When charging the coal into the carbonizing chamber 2 of the coke oven facility 1, the coal is charged into the coal charging inlet 9 provided at the top of the furnace of the carbonizing chamber 2 through the coal charging sleeve cover 10 of the coal loading vehicle 3. . At that time, the dust-proof hood 8 covers the outer periphery of the upper surface of the coal charging inlet 9 and prevents dust from scattering from the gap between the coal charging sleeve cover 10 and the coal charging inlet 9. The dust-proof hood 8 is lowered from the coal-coating vehicle 3 to cover the outer periphery of the upper surface of the coal charging inlet 9 before removing the furnace cover covering the coal charging inlet 9 by a lifting magnet device described later.

  3-5 is explanatory drawing of the lifting magnet apparatus 11 provided in the charcoal vehicle 3. FIG. As described above, the lifting magnet device 11 is for removing the furnace cover that covers the coal charging inlet 9. For example, as shown in FIG. 5a, the lifting magnet device 11 includes a truncated cone-shaped lifting magnet 12 supported by two arms 13 from both sides in the radial direction, and protective plates 14 arranged on both outer sides thereof. Is done. The lifting magnet device 11 has the longitudinal direction of the arm 13 aligned with the coal charging inlet 9 provided in the single carbonizing chamber 2 and is lowered from the coal-coating vehicle 3, and then in the direction of the arrow in FIG. 4. That is, the lifting magnet 12 can be swung by the arm 13 so as to be twisted in the circumferential direction. Therefore, when the lifting magnet device 11 is lowered from the charcoal vehicle 3 so that the lifting magnet 12 is positioned above the furnace lid, and the lifting magnet 12 is swung in this state, the furnace lid 15 is moved as shown in FIG. It is detached from the coal charging inlet 9 and magnetically attached to the lifting magnet 12, and the furnace lid 15 is removed from the coal charging inlet 9. The lifting magnet 12 is an electromagnet that is excited by electric power. Further, the lifting magnet device 11 can be reciprocated in the direction of the arrow in FIG.

  FIG. 6 is a control device for the entire coke oven equipment including the dustproof hood and lifting magnet device described above. The left side of the figure represents the ground equipment (fixed equipment) 22 and the right side of the figure represents the mobile device. The machine representatively shows three charcoal vehicles 3 and one extruder 4. In the mobile device of this embodiment, two computers 16 and 17 called programmable controllers are installed, and a terminal 18 directly connected to one computer 17 is installed. Both of the two computers 16 and 17 have an advanced arithmetic processing function. Among these, the computer 16 not directly connected to the terminal 18 is an automatic operation computer, and the computer 17 directly connected to the terminal 18 is an automatic operation stop monitoring computer. The operation automatic operation computer 16, the automatic operation stop monitoring computer 17, and the terminal 18 are arranged in the electric room and the operation room of the mobile device. However, there is usually no operator in both the electric room and the operation room. .

  On the other hand, on the ground facility 22, similarly, two computers 19 and 20 including programmable controllers and a terminal 18 directly connected to one computer 20 are arranged. These computers 19 and 20 also have advanced arithmetic processing functions. Among these, the computer 19 that is not directly connected to the terminal 18 is a mobile device automatic operation computer, and the computer 20 that is directly connected to the terminal 18 is an automatic operation stop aggregation computer. The mobile operation automatic operation calculator 16 and the automatic operation stop monitoring computer 17 and the ground equipment mobile operation automatic operation computer 19 and the automatic operation stop aggregation computer 20 exchange information with each other by wireless communication. Can do. The mobile terminal 18 and the ground equipment terminal 18 have display functions such as a screen display function and a printing function.

  In the operation automatic operation computer 16, calculation processing for automatic operation to be performed by each mobile device necessary for operation of the coke oven equipment is input or stored in advance in each mobile device, and the arithmetic processing is performed according to the set procedure. To perform automatic operation of equipment. Automatic operation of equipment is given a plurality of preset operation process names, and the operation states within a preset range are set in order for each operation process name, and calculated for each operation state. Processing is set. In the arithmetic processing set for each operation state, an operation condition for shifting to the next operation state is set. For example, in the process of “first lid removal tank” for removing the first (one tank) furnace lid among four furnace lids arranged for a single carbonization chamber, one dustproof hood is lowered. Then, the lifting magnet device of one tank is lowered, then the lifting magnet of one tank is strongly excited, and then the shaking is stopped after the lifting magnet apparatus of one tank is swung, and then the strong excitation of the lifting magnet of one tank is performed. Is stopped, and then the progress (flow) of the operating state is set to raise the lifting magnet device of one tank. Then, an operation condition (interlock) is set for each operation state, and automatic operation is stopped if the operation condition is not achieved within, for example, a preset required time.

  However, for example, if the equipment stops in the middle of the furnace cover removal process, heat leaks from, for example, the coal charging inlet. Therefore, in the automatic operation calculator 16, after the automatic operation is stopped, the operation state proceeds. The operation process is forcibly shifted from the calculation process to the calculation process for closing the furnace cover, and the furnace cover is closed. As described above, in this embodiment, the operator is not present in either the electric room or the cab, so when the automatic operation is stopped, the operator goes to the cab or the electric room after the automatic operation is stopped. The cause of automatic shutdown must be checked. However, at that time, even when looking at the calculation processing state of the computer 16 for automatic operation of the operation, since the calculation processing itself has shifted from the calculation processing at the time of stopping the automatic operation, it is understood that the automatic operation has stopped. However, the cause of the automatic operation stop cannot be determined from the state of the arithmetic processing of the operation automatic operation computer 16.

  Therefore, in this embodiment, the calculation process shown in FIG. 7 is performed by the automatic operation stop monitoring computer 17, and information for determining the cause of the automatic operation stop is determined from the operation state and the operation condition when the automatic operation is stopped. provide. That is, by executing the arithmetic processing of FIG. 7 in the automatic operation stop monitoring computer 17, the automatic operation stop cause providing device and the method thereof are constructed in the automatic operation stop monitoring computer 17. From the operation automatic operation computer 16 to the automatic operation stop monitoring computer 17, an operation process name corresponding to a calculation process executed by the operation automatic operation computer 16 and an operation in a range corresponding to the operation process name are performed. In addition to the state and the operating conditions set in each operation state, an automatic operation stop flag set when the automatic operation of the facility is stopped is transmitted. Incidentally, the arithmetic processing of FIG. 7 is a generic expression that is applied to all mobile devices. For example, the details of the operation process name, operation state, and operating conditions described above differ for each type of mobile device. Further, the automatic operation stop flag is canceled when the operation is restored. Although the operation recovery is based on the operation of the automatic operation start button as a rule, it also includes a case where the operation is recovered by, for example, an operator intervening as described later and setting a spare mobile device in an operating state.

  The arithmetic processing in FIG. 7 is started with the start of the automatic operation of the facility by the automatic operation operation computer 16. First, in step S 1, the operation state and operation conditions of the facility by the automatic operation operation computer 16 are always read. . In reading, for example, the operation state for each operation process name and the operation conditions set in each operation state are read for each operation process name. Note that the read operation state and operation condition may be displayed on the terminal 18 in real time.

Next, the process proceeds to step S2, where it is determined whether or not the automatic operation stop flag is transmitted from the operation automatic operation computer. If the automatic operation stop flag is transmitted, the process proceeds to step S3. Moves to step S6.
In step S3, the operation state and the operation condition when the automatic operation stop flag is transmitted (when the automatic operation stop flag is established in the figure) are held. At the time of holding, the operation state for each operation process name and the operation condition set in each operation state are held for the operation process name. In addition, you may make it hold | maintain about the preset range before and behind automatic driving | operation stop for the holding range of an operation state and an operating condition.

Next, it transfers to step S4 and memorize | stores in the memory | storage device which does not illustrate the operation state and operating condition which cause an automatic driving | operation stop. In storing, the operation state for each operation process name and the operation condition set in each operation state are stored for each operation process name. In addition, you may make it memorize | store the memory | storage range of an operation state and an operating condition about the range set beforehand before and after an automatic driving | operation stop.
Next, the process proceeds to step S5, the operation state and the operation condition causing the automatic operation stop are displayed on the terminal 18, and the process is terminated. In the display, as described later, the operation process name, the operation state of the operation process name, and the operation condition set in the operation state are displayed in this order. Further, when the operation state and the operation condition are held and stored for a preset range before and after the automatic operation stop, they may be sequentially displayed according to an instruction from the operator.

On the other hand, in step S6, it is determined whether or not the operation of the facility has ended. If the operation has ended, the process ends. If not, the process proceeds to step S1.
In this calculation process, the operation state of the range set for each operation process name and the operation condition set in each operation state are always read from the calculation process executed by the automatic operation operation computer 16, and the automatic operation is stopped. When the flag is transmitted, the operation state and the operation condition in the range of the operation process name when the automatic operation stop flag is transmitted are held, stored, and displayed on the terminal 18. The display content on the terminal 18 is set as follows, for example. First, as shown in FIG. 8, a new automatic operation stop state name is displayed on the terminal 18 as shown in FIG. 8, and the latest automatic operation stop state is related to the operation process name “1 capping tank”, for example, It is displayed with the automatic operation stop state name "Covering 1 tank block time over" This means that, for example, the automatic operation has been stopped because the operation time of the “lider 1 tank” exceeds the required time with respect to the required time set in advance in the operation process of the “lider 1 tank”.

  Next, when the “operation state” being displayed is selected, a flowchart shown in FIG. 9 appears. This flowchart is the operation state of the above-mentioned “one lid removal tank”, and means that the operation state has progressed to the step surrounded by the double line in the figure. In other words, in the current “one lid removal tank” step, the operation state has progressed to “one tank lifting magnet lowering (under the lifting magnet in the figure)”. Note that the display of the progress of the operation state is not limited to this, and for example, changing the brightness and hue of the entire step can be mentioned.

  Next, for example, when the step “under 1 tank riff mug” is selected, the operation condition table shown in FIG. 10 appears. In this operation condition table, there are three operation conditions of “under one tank riff mug”: “traveling stopped”, “hydraulic pump activated”, and “one tank sleeve upper limit”. It can be seen that the operating condition is satisfied because “O” is attached to “pump activation”. On the other hand, the “one tank sleeve upper limit” is not given “◯” that satisfies the operating condition, and therefore the “1 tank sleeve upper limit” operating condition is not satisfied. As a result, it is found that the automatic operation stop of the “covering 1 tank block time over” has been reached. Note that the display of whether or not the operating condition is satisfied is not limited to this, and for example, changing the luminance or color of a column in the table can be mentioned.

  On the other hand, the mobile device automatic operation computer 19 of the ground facility 22 is for monitoring and controlling the automatic operation of the 14 mobile devices described above. The automatic operation stop aggregation computer 20 is based on the mobile device. It is intended to summarize the contents of the automatic operation stop that occurred during the facility operation. Among these, the automatic operation stop aggregation computer 20 performs the arithmetic processing shown in FIG. 11 to collect the automatic operation stop contents in the 14 mobile devices. The arithmetic processing in FIG. 11 is executed, for example, in a predetermined sampling cycle. First, in step S11, it is determined whether or not an automatic operation stop flag is transmitted, and when the automatic operation stop flag is transmitted. Shifts to step S12, and returns otherwise.

In step S12, the operation state and the operation condition when the automatic operation stop flag is established, which is held by the automatic operation stop monitoring computer 17 when the automatic operation stop flag is transmitted, are read by the arithmetic processing of FIG.
Next, the process proceeds to step S13, and the timer held in the computer is operated.
Next, the process proceeds to step S14, where it is determined whether or not the automatic operation stop flag is released. If the automatic operation stop flag is released, the process proceeds to step S15. Otherwise, the process proceeds to step S13. .

In step S15, the timer in the computer is stopped.
Next, the process proceeds to step S16, and the current automatic operation stop time is read from the timer stopped in step S15.
Next, the process proceeds to step S17, and the operation state and operation condition that caused the current automatic operation stop are related to the calculated automatic operation stop time and stored in a storage device (not shown).

Next, the process proceeds to step S18, and the operation state and operation condition causing the automatic operation stop and the automatic operation stop time related in step S17 are output to the mobile unit automatic operation computer 19 and then returned.
Further, in the mobile device automatic operation computer 19, the arithmetic processing shown in FIG. 12 is performed, and the automatic operation is performed to evaluate the situation. The arithmetic processing in FIG. 12 is executed, for example, in a predetermined sampling period. First, in step S21, the automatic operation stop time within a predetermined period set in advance is set for each operation state and operation condition causing the automatic operation stop. To accumulate.

Next, the process proceeds to step S22, and the number of times of automatic operation stop of the operation state and the operation condition that cause the automatic operation stop is calculated.
Next, the process proceeds to step S23, in which the automatic operation stop cumulative time calculated in step S21 is divided by the number of automatic operation stop calculated in step S22, and the automatic operation for each operation state and operation condition causing the automatic operation stop. Calculate the average shutdown time.

Next, the process proceeds to step S24, and the automatic operation stop state is determined for each operation state and operation condition that caused the automatic operation stop based on the accumulated automatic operation stop time / number / average time calculated in steps S21 to S23. Return after evaluating.
According to these arithmetic processes, every time the automatic operation stop of the facility occurs, the operation state and the operation condition that cause the automatic operation stop and the automatic operation stop time are associated and stored. Then, the automatic operation stop state is evaluated for each operation state and operation condition causing the automatic operation stop based on the accumulated automatic operation stop time, number of times, and average time. The automatic operation stop time, so-called down time, generally, the greater the accumulated time, the more the cause, that is, the operating state and operating conditions are evaluated. It may be evaluated when the average automatic shutdown time is large. Since a large automatic operation stop cumulative time means a short operation time, generally an early response or a fundamental countermeasure is required. However, since a large number of automatic operation stops means that the operation is frequently stopped, an early response or a drastic measure may be necessary depending on the case. In addition, since a large average automatic operation stop time may mean a serious abnormality or failure, an early response or a drastic measure may be required in some cases. The automatic operation stop situation is evaluated in consideration of these factors. As can be inferred from the above description, when the automatic operation average time is large, for example, the automatic operation stop cumulative time can be reduced by operating a spare mobile device and returning the operation. Therefore, in this embodiment, even when the operator intervenes in this way and the operation returns, the time until that time is set as the automatic operation stop time.

  As described above, in the automatic operation stop cause providing apparatus and the method thereof according to this embodiment, the coke oven facility 1 is automatically operated by the operation automatic operation computer 16 having the arithmetic processing function and the state changes after the automatic operation is stopped. On the other hand, an object of the present invention is to provide a cause of automatic operation stop of the coke oven facility 1 by the automatic operation stop monitoring computer 17 having an arithmetic processing function. Therefore, the operation state of the coke oven facility 1 and the operation conditions necessary for the progress of the operation state are always read in the operation state / operation condition reading step S1. When the automatic operation stop of the coke oven facility 1 is detected in the automatic operation stop detection step S2, the operation state and the operation condition at the time of the automatic operation stop are retained in the operation state / operation condition retention step S3, and the retained automatic operation is retained. The operation state and operation condition at the time of stop are stored in operation state / operation condition storage step S4. Therefore, the cause of the automatic operation stop is determined from the operation state and the operation condition at the time of the automatic operation stop held and stored.

  Further, as the operation state and operation condition of the coke oven facility 1 when the automatic operation is stopped, the operation state and operation condition of the coke oven facility 1 are held for the operation state within a preset range. Thereby, it becomes possible to determine the cause of the automatic operation stop more accurately. Further, if the operation state and operating conditions of the coke oven facility 1 are maintained for the operation state within a preset range before and after the automatic operation stop, the operator operates the facility after the automatic operation stop as in this embodiment. When checking the state, the cause of the automatic operation stop can be checked before and after the automatic operation stop, and as a result, the cause of the automatic operation stop can be determined more accurately.

Further, when storing the operation condition and the operation condition of the coke oven facility 1 when the automatic operation is stopped, the operation state in the preset range that is held is stored in association with the preset operation process name. This makes it possible to determine the cause of the automatic operation stop more easily and easily.
In addition, the operation state and operation condition of the coke oven equipment 1 at the time of the automatic operation stop held and stored are displayed in the operation state / operation condition display step S5, so that the cause of the automatic operation stop can be more easily and easily understood. Easy and accurate judgment can be made.

  In addition, the operation recovery of the equipment whose automatic operation is stopped in the operation recovery detection step S14 is detected, the automatic operation stop time of the equipment is detected in the automatic operation stop time detection step S16, and the automatic operation stop is performed in the automatic operation stop time storage step S17. The time is stored in relation to the operating state and operating conditions of the equipment when automatic operation is stopped. Thereby, the automatic operation stop time is statistically obtained for each operation state and operation condition causing the automatic operation stop.

  Further, in the automatic operation stop state evaluation step S24, the automatic operation stop is caused based on the automatic operation stop accumulation time, the automatic operation stop count, and the automatic operation stop average time of the automatic operation stop time for each operation state and operation condition of the equipment. The automatic operation stop status is evaluated for each operating state and operating condition of the equipment. Thereby, an automatic driving | operation stop condition can be comprehensively evaluated for every operation state and operating condition of an installation.

  In the above-described embodiment, the calculation process for providing the cause of automatic driving stop, specifically, the calculation process of FIG. 7, the calculation process for calculating the automatic driving stop time, specifically, the calculation process of FIG. The calculation processing for evaluating the automatic operation stop condition, specifically, the calculation processing of FIG. 12 is performed by three different computers, but these calculation processing is performed alone, two or four or more. You may make it perform with the computer of. Further, not only a single automatic operation stop but also a plurality of automatic operation stops may be detected and displayed simultaneously.

  Moreover, the automatic operation stop cause providing apparatus and method of the present invention can be applied not only to the coke oven equipment but also to any automatic operation equipment in the steelworks. Further, the present invention can be applied not only to the steelworks but also to automatic operation equipment whose state changes after stopping automatic operation in all industrial fields.
