[0011] <Embodiment> Embodiments of the present invention will now be described in detail. The information processing system for limestone calcination, the information processing program for limestone calcination, and the information processing method for limestone calcination described below are intended to embody the technical concept of the present invention, and unless otherwise specified, the present invention is not limited to the following.

[0012] (Information processing system for limestone calcination) Figure 1 is a schematic diagram showing an information processing system 10 for limestone calcination according to an embodiment of the present invention. The information processing system 10 for limestone calcination according to this embodiment is an information processing system that processes information related to limestone calcined in a vertical calcination furnace 70. The information processing system 10 for limestone calcination comprises an information processing device 100 that processes information related to limestone calcined in a vertical calcination furnace 70, a server (external storage device) 50 as a database, an external system 60 located at a distance from the information processing device 100, and a vertical calcination furnace 70 that produces calcined bodies such as quicklime and quicklime-containing materials by calcining limestone inside its furnace.

[0013] The information processing device 100, the server 50, the external system 60, and the vertical firing furnace 70 are interconnected and can communicate with each other. These devices may also be interconnected and can communicate with each other via a private network, such as a local network or an intranet. When connected by wireless communication, the limestone firing information processing system 10 may further include one or more access points AP.

[0014] FIG. 2 is a functional block diagram showing the information processing apparatus 100 of the present embodiment. The information processing apparatus 100 is an electronic computer such as a desktop personal computer, a notebook personal computer, or a tablet terminal. The information processing apparatus 100 includes an input unit 110, a display unit 120, a control unit 130, and a storage unit 140.

[0015] The input unit 110 is constituted by input devices such as a keyboard, a mouse, a touch pad, etc., for example. By operating the input unit 110, information normally required in the information processing apparatus 100 is input.

[0016] The display unit 120 has a display as a display device. In addition to the screen display function normally required in the information processing apparatus 100, for example, as shown in FIGS. 4, 6, and 7, an input screen 122, a display first screen 124, a display second screen 126, etc. are displayed. Further, the display unit 120 may be constituted by a touch panel having the function of the input unit 110. When the display unit 120 is constituted by a touch panel, the user inputs information regarding the firing of limestone to the information processing apparatus 100 by operating the display unit 120, for example.

[0017] Note that the configurations of the input unit 110 and the display unit 120 are not limited to the above-described configurations. Instead of these input unit 110 and display unit 120, as long as it has an equivalent function (for example, display means and input means that can be used remotely, etc.), it is not limited thereto.

[0018] The control unit 130 is constituted by an integrated arithmetic processing device having a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit), for example. As shown in FIG. 2, the control unit 130 includes an acquisition unit 132, a generation unit 134, a decoding unit 135, a recording unit 136, and a display control unit (changing unit) 138.

[0019] The acquisition unit 132 is configured to acquire area information and firing information, which will be described later. The generation unit 134 is configured to generate code information D1 that associates the area information and the firing information (see FIG. 5). The recording unit 136 is configured to record the code information D1 in the database 50. The decoding unit 135 is configured to decode the area information and the firing information from the code information D1 recorded in the database 50. The display control unit 138 is configured to change the display of the input display area (input area) 122E displayed on the display unit 120 (see FIG. 4).

[0020] The storage unit 140 has a storage medium such as a HDD (Hard Disk Drive) or SSD (Solid State Drive) and stores various data in a readable and writable manner. As shown in FIG. 2, the storage unit 140 stores a firing information master 142 and a screen display master 144. The storage unit 140 also stores a limestone firing information processing program 146 necessary for controlling each part of the limestone firing information processing system 10.

[0021] The limestone firing information processing program 146 causes the information processing apparatus 100 as a computer to execute the processes of the acquisition unit 132 acquiring the area information and the firing information, the generation unit 134 generating code information that associates the area information and the firing information, and the recording unit 136 recording the code information in the database 50.

[0022] As shown in FIG. 1, the database 50 is a server having a storage medium such as a HDD or SSD. Since the database 50 can adopt various known configurations, a detailed description thereof is omitted. The database 50 includes the code information D1 recorded by the recording unit 136.

[0023] The external system 60 is not particularly limited as long as it records operational information of the vertical firing furnace 70, and examples include a computer such as a desktop PC. The operational information acquired from the vertical firing furnace 70 and recorded in the external system 60 is acquired by the information processing device 100 by the acquisition unit 132 shown in Figure 2. The recording unit 136 is configured to write and record the operational information acquired from the external system 60 by the acquisition unit 132 into the database 50. The operational information recorded in the external system 60 is not particularly limited, but examples include the temperature of the circulating gas inside the furnace of the vertical firing furnace 70, the temperature of the combustion chamber, and the values ​​of residual carbon dioxide and silicon dioxide in the fired body.

[0024] In the vertical firing furnace 70, upward-flowing gases generated from fuel and other sources within the furnace come into countercurrent contact with the limestone C that has been introduced and packed (deposited) into the furnace. The firing conditions for the limestone C, such as the temperature inside the furnace, the temperature at which the fuel is introduced, and the flow rate of the fuel, are not particularly limited and can be changed as appropriate. In this embodiment, a Beckenbach furnace is given as an example of the vertical firing furnace 70. However, there are no particular limitations to the vertical firing furnace 70, and in addition to the Beckenbach furnace, other examples of vertical firing furnaces include Merz furnaces, co-firing furnaces, shaft kilns, and koma-type furnaces.

[0025] As shown in Figure 1, the vertical firing furnace 70 comprises a furnace body 71, which is the main body of the furnace; a furnace bottom 72 located below the furnace body 71 and capable of discharging fired products to the outside of the furnace body 71; and a support portion 73 that supports the furnace body 71. The furnace body 71 comprises a long cylindrical outer cylinder 71A, a long cylindrical inner cylinder 71B located inside the outer cylinder 71A, and a table 74 fixed to the support portion (base portion) 73 which serves as a base, and is formed as a vertical cylindrical shape extending along the vertical direction. The inner cylinder 71B is formed to be longer than the outer cylinder 71A in the axial direction (vertical direction) and is arranged coaxially with the outer cylinder 71A, with the upper end of the inner cylinder 71B located above the outer cylinder 71A. Furthermore, the inner diameter of the inner cylinder 71B is made smaller than the inner diameter of the outer cylinder 71A so as to form a raw material vertical passage 75A between the inner circumferential surface of the outer cylinder 71A and the outer circumferential surface of the inner cylinder 71B that has sufficient space for limestone C and the like to flow through.

[0026] The vertical calcination furnace 70 is equipped with a flow path 75 through which the calcined limestone C passes. The flow path 75 comprises a vertical raw material passage 75A, which extends in the vertical direction, and a horizontal raw material passage 75B, which extends from the lower end of the vertical raw material passage 75A in the radially outward direction of the furnace body 71 (lateral direction: from the inner cylinder 71B toward the outer cylinder 71A). The vertical raw material passage 75A is a passage through which the limestone C moves downward while being calcined within the flow path 75. The part of the vertical raw material passage 75A through which the limestone C is calcined is sometimes called the combustion chamber. The horizontal raw material passage 75B is a passage within the flow path 75 that intersects with the vertical raw material passage 75A, and is a passage through which the calcined limestone C moves in the radially outward direction of the furnace body 71. The raw material lateral passage 75B is formed inside the table 74, which is located in the lower part of the furnace body 71 and is supported by the support section 73. The table 74 is equipped with an inspection opening 76, which allows an operator to visually inspect the raw material lateral passage 75B inside the furnace from outside the furnace body 71 and to remove the limestone C.

[0027] Multiple flow paths 75 (raw material vertical passage 75A and raw material horizontal passage 75B) and inspection openings 76 are provided along the circumferential direction of the furnace body 71. The number of multiple flow paths 75 in one vertical firing furnace 70 is not particularly limited, but for example, it may be around 8 to 10. Each of the multiple flow paths 75 is numbered sequentially along the circumferential direction of the furnace body 71. For example, in the case of a total of 10 flow paths 75, they are numbered 1, 2, ..., 10 along the circumferential direction of the furnace body 71. The number of multiple inspection openings 76 in one vertical firing furnace 70 is not particularly limited, but may be less than or equal to the number of multiple flow paths 75, for example, it may be around 8. The multiple inspection openings 76 are numbered sequentially along the circumferential direction of the furnace body 71, similar to the multiple flow paths 75. For example, in the case of a total of eight inspection ports 76, each port is numbered table number 1, table number 2, ..., table number 8 along the circumferential direction of the furnace body 71. One inspection port 76 is assigned to one or more raw material lateral passages 75B. One or more raw material lateral passages 75B (the entire area A0 described later) can be visually inspected from one inspection port 76. For example, raw material lateral passages 2 and 7 can be visually inspected from inspection port 76 of table number 1, and raw material lateral passage 75B 3 can be visually inspected from inspection port 76 of table number 2 (see combustion chamber display areas 122A, 122B in Figure 4).

[0028] Figure 3 shows a view of the raw material lateral passage 75B from an arbitrary inspection opening 76. The raw material lateral passage 75B that can be visually inspected from the inspection opening 76 is divided into two or more areas. For example, if the entire area of ​​one raw material lateral passage 75B that can be visually inspected from the inspection opening 76 is called A0, then this entire area A0 is divided into six areas A1 to A6. In this case, the area located radially outside the furnace body 71 (outer cylinder 71A side: upper side of the paper) is divided sequentially as areas A1 to A3 in the circumferential direction (from left to right on the paper), and the area located radially inside the furnace body 71 (inner cylinder 71B side: lower side of the paper) is divided sequentially as areas A4 to A6 in the circumferential direction (from left to right on the paper).

[0029] In each of areas A1 to A6, there is fired limestone C. In the entire area A0, the area (one of areas A1 to A6) to which any limestone C belongs is called area information. The area information can also be called the position information of limestone C, which represents the position where limestone C is arranged in the raw material cross passage 75B (the entire area A0).

[0030] An operator visually checks the raw material cross passage 75B from any inspection port 76, and also takes out and breaks the limestone C arranged in areas A1 to A6 from the inspection port 76, and checks the cross section thereof, so as to check the firing degree etc. of the limestone C arranged in areas A1 to A6 (this operation is called table check). Regarding limestone C, the information on the degree of its firing (firing degree) is called firing information.

[0031] As shown in FIG. 5, in the firing information master 142, the firing degree of limestone, the symbol corresponding to the firing degree, and the numerical code corresponding to the firing degree are registered. Five major classifications of "undercooked", "normal (good)", "overcooked", "lump (sticking)", and "lowering of the fire layer" are registered for the firing degree respectively. For the symbols, the symbol "big 4" etc. corresponding to the undercooked firing degree, "〇" corresponding to normal, "△" corresponding to overcooked, "×" corresponding to lump, and "fire" corresponding to the lowering of the fire layer are registered respectively. For the numerical codes, the numerical values "1" corresponding to the undercooked firing degree, "2" corresponding to normal, "3" corresponding to overcooked, "4" corresponding to lump, and "5" corresponding to the lowering of the fire layer are registered respectively.

[0032] The degree of firing is determined by a worker performing a table check. "Underfired" indicates a state where some limestone remains unburned. "Normal" indicates a state where there is no unburned limestone. "Overfired" indicates a state where the limestone is discolored black, hard, and difficult to break. "Lump" indicates a state where the limestone has fused together and formed a lump. "Fire layer reduction" indicates a state where there is luminescence due to combustion. Furthermore, "Underfired" is classified into a subcategory such as "Large 4," which combines the first subcategory of "Large," "Medium," and "Small" with the second subcategory such as "4" and "8." This subcategory is also registered as a symbol. Regarding the first subcategory of "Underfired," "Large" indicates a state where more than 1 / 2 of the cross-sectional area of ​​the broken limestone remains unburned, "Medium" indicates a state where 1 / 4 to 1 / 2 of the cross-sectional area of ​​the broken limestone remains unburned, and "Small" indicates a state where less than 1 / 4 of the cross-sectional area of ​​the broken limestone remains unburned. The numbers "4" and "8" in the second subcategory of "under-fired" indicate the number of under-fired limestones per 100 limestones. For example, if, among the limestones placed in areas A1 to A6, there are 8 limestones per 100 limestones that have unfired areas where less than 1 / 4 of the cross-sectional area of ​​the broken surface is unfired, then the worker will determine that the degree of firing of the limestone in that area is "under-fired" and the symbol is "minor 8". This degree of firing and symbol is called firing information. Note that firing information may consist of at least one of the following: degree of firing and / or symbol.

[0033] The screen display master 144 shown in Figure 2 registers the basic configuration of screen displays such as the input screen 122, the first display screen 124, and the second display screen 126 shown in Figures 4, 6, and 7 (for example, the screen's subject, item name, and the frames of each area). The display control unit 138 displays the basic configuration of the input screen 122 and other screens registered in the screen display master 144 on the display unit 120, and is configured to display characters, figures, symbols, etc., for each screen, or change their display, based on predetermined inputs made by users such as operators and administrators using the input unit 110. Unless otherwise specified, the following configurations for each screen 122, 124, and 126 can be displayed on the display unit 120 by the display control unit 138 performing predetermined controls.

[0034] As shown in Figure 4, the input screen 122 includes a combustion chamber display area 122A, firing information display areas 122B and 122C, firing furnace display area 122D, and an input display area (input area) 122E.

[0035] The combustion chamber display area 122A is any vertical firing furnace selected from the multiple vertical firing furnaces displayed in the firing furnace display area 122D (in this embodiment, furnace A out of furnaces A to D). The system is configured to display the numbers of multiple flow paths 75 (more specifically, the combustion chambers corresponding to the flow paths 75).

[0036] The firing information display area 122B is configured to display a table number display area 122B1 that displays table numbers 1 to 8 for multiple inspection ports 76, an area firing information display area 122B2 that displays firing information for each area of ​​the inspection port 76 for each table number, and an operation information display area 122B3 that displays operation information acquired from an external system 60. The firing information display area 122B is configured to display the area firing information display area 122B2 one row at a time from top to bottom. When any area firing information display area 122B2 is selected in the firing information display area 122B, it is displayed as the selected firing information display area 122C. Similarly, the firing information display area 122C is configured to display a table number display area 122C1, an area firing information display area 122C2, and an operation information display area.

[0037] In the firing information display area 122B, when an arbitrary area firing information display area 122B2 (for example, in Figure 4, the area firing information display area 122C2 for table number 7 in the row with flow path number "2" on "April 30th") is selected, the selected firing information display area 122C is recognized, and a frame 122C4 surrounding the selected area firing information display area 122C2 and information such as "Furnace A Table Check Record Registering" are displayed. In addition, in the firing furnace display area 122D, a frame 122D4 surrounding that table number is displayed, and firing information for that table number can be entered in the input display area 122E.

[0038] The input display area 122E includes a plurality of firing degree selection buttons 122E1 that allow selection of firing degree, etc., registered in the firing information master 142, and a selection display area 122E2 that displays information related to the area firing information display area 122C2 selected in the firing information display area 122C. The selection display area 122E2 includes a division area 122E3 divided into multiple areas (in Figure 4, a total of 6 areas: 3 horizontally and 2 vertically), a sub-category selection button 122E4 that allows selection of a sub-category of "underbaked" (first sub-category and second sub-category) registered in the firing information master 142, and table change buttons 122E5 and 122E6 that allow changing the selection display area 122E2 to one of the table numbers (8 and 6) adjacent to the selected table number (7).

[0039] As shown in Figure 5, the partitioned area 122E3 is divided into several sub-regions E1 to E6 (referred to as the 1st partitioned area E1 to the 6th partitioned area E6, respectively). The display positions of the multiple sub-regions E1 to E6 in partitioned area 122E3 correspond to area information. Specifically, the display positions of the 1st partitioned area E1 to the 6th partitioned area E6 correspond to the same positions (in the same order) as areas A1 to A6 in Figure 3. For example, the 1st partitioned area E1, displayed on the upper left side (one side) of partitioned area 122E3, is positioned to correspond to area A1, which is located on the left side of the radially outer side of the furnace body 71 (outer cylinder 71A side) in the entire area A0. When the firing information "Middle 08" is displayed in the 1st partitioned area E1, users such as workers and managers can understand that the firing information for the limestone whose area information is "Area A1" is "Middle 8". Furthermore, the display "08" and the symbol "8" are considered synonymous.

[0040] Multiple sub-regions E1 to E6 within the division region 122E3 can each be selected simultaneously by one or more people. As shown in Figure 5, when any sub-region of the division region 122E3 (the first division region E1 in Figure 5) is selected, a frame 122E7 surrounding the selected region is displayed (see Figure 4). In this state, if any of the firing degree selection buttons 122E1 are selected, the symbol corresponding to the selected firing degree (major category) is read from the firing information master 142 and displayed in the aforementioned arbitrary sub-region. If "Underbaked" is selected from the firing degree selection buttons 122E1, a sub-category selection button 122E4 is displayed adjacent to the arbitrary sub-region (above the first division region E1). When this sub-category selection button 122E4 is selected, the sub-categories (first sub-category and second sub-category) of "Underbaked" registered in the firing information master 142 are read and displayed, for example, in a pull-down format, and the sub-category becomes selectable. When a subcategory is selected, the symbol corresponding to that selected subcategory is displayed in the first category area E1.

[0041] Furthermore, if multiple sub-regions E1 to E6 of the division area 122E3 are selected simultaneously (two or more), and one of the firing degree selection buttons 122E1 is selected, the firing degree can be registered for the selected sub-regions all at once. This state of having multiple sub-regions selected simultaneously can be cleared by selecting the clear button among the firing degree selection buttons 122E1.

[0042] The acquisition unit 132 shown in Figure 2 is configured to acquire the firing degree selected by the firing degree selection button 122E1 (it acquires the firing information entered in the input display area 122E). The display control unit 138 is configured to change the display of the aforementioned small area (first division area E1 shown in Figure 4) based on the firing information acquired by the acquisition unit 132. The format of the display change of the division area 122E3 by the display control unit 138 is not particularly limited, but for example, the background color or text color of any small area may be changed based on the firing degree. Also, if adjacent small areas have the same firing degree, those adjacent small areas may be combined and displayed as one medium area, and the same firing degree may be displayed once in that medium area. Furthermore, if the entire division area 122E3 has the same firing degree, the entire division area 122E3 may be combined and displayed as one large area, and the same firing degree may be displayed once in that large area.

[0043] As shown in Figure 6, the first display screen 124 includes a firing information display area 124A, a firing content display area 124B, and a statistical analysis display area 124C. The firing information display area 124A is configured to display a table number display area 124A1, an area firing information display area 124A2, and an operation information display area 124A3, and each area is capable of displaying the same information as the firing information display area 122B on the input screen 122.

[0044] The firing distribution display area 124B includes a schematic main display area 124B1 in which the selected firing furnace is schematically shown in a circular frame in plan view, a schematic distribution display area 124B2 in which firing information is displayed in a predetermined format in the schematic main display area 124B1, and an operation information display area 124B3 that displays operation information acquired from an external system 60. The schematic main display area 124B1 displays the numbers 1 to 10 of multiple flow channels 75 (combustion chambers) and the table numbers 1 to 8 of multiple inspection ports 76 in an area divided by multiple arcs within its circular frame. The schematic distribution display area 124B2 is displayed in the arc area outside the arcs in which the table numbers are displayed. In the schematic distribution display area 124B2, firing information for each area A1 to A6 based on code information D1 acquired from the database 50 by the acquisition unit 132 is displayed by the display control unit 138, for example, in different colors.

[0045] The statistical analysis display area 124C includes multiple graph display areas 124C1 that allow the display control unit 138 to display, as color-coded bar graphs, the firing information (for example, the number of "under-baked," "normal," and "over-baked" items) counted by the control unit 130 for each table number of multiple inspection openings 76 over any given period (such as one week or one month).

[0046] As shown in Figure 7, the second display screen 126 includes a firing information display area 126A that can display the same information as the firing information display area 122B in the input screen 122 for any firing furnace, a schematic cross-section display area 126B that schematically shows the vertical cross-section of the firing furnace, and operation information display areas 126C and 126D that display operation information acquired from the external system 60.

[0047] The operation information display area 126C includes an item display area 126C1 in which the process of loading limestone into the firing furnace and the names of each part of the firing furnace are displayed as multiple items in order from top to bottom; multiple time display areas 126C2 in which the arrival time (passage time) of the limestone is displayed for each of the multiple item display areas 126C1; and multiple operation information detail display areas 126C3 in which operation information is displayed side by side for each of the multiple time display areas 126C2 and for each of the multiple flow path 75 (combustion chamber) numbers.

[0048] (Information processing method for limestone calcination) Next, the information processing method for limestone calcination will be explained with reference to the flowchart in Figure 8. The following information processing method for limestone calcination is basically carried out by having the information processing device 100, which acts as a computer, execute each process using the limestone calcination information processing program 146 shown in Figure 2.

[0049] As shown in Figure 8, the limestone calcination information processing method involves a user U who has performed a table check operating the input unit 110 shown in Figure 2 to input information, an acquisition unit 132 acquiring area information for each of the two or more divided areas A1 to A6 (Figure 3), and calcination information for each limestone placed in each area A1 to A6 (S10), a display control unit 138 displaying the calcination information on the display unit 120 (S20), a generation unit 134 generating code information D1 that links the area information and calcination information (S30), and a recording unit 136 recording the code information D1 on the server (database) 50 (Figure 1) (S40). Subsequently, in S50, the acquisition unit 132 acquires the operation information from an external system 60 that has acquired operation information from the vertical calcination furnace 70 (S60), and the recording unit 136 records the operation information on the server 50 (S70). Next, the acquisition unit 132 acquires the code information and operation information recorded in the server 50 (S80), and the decoding unit 135 decodes the area information and firing information from the code information D1, which the display control unit 138 then displays on the display unit 120 (S90). User U may change the firing conditions of the vertical firing furnace 70 based on the information displayed on the display unit 120 (S100).

[0050] In S10, a table check is performed, and the user U operates the input unit 110. By selecting the firing degree, etc. in a plurality of small areas E1 to E6 of the divided area 122E3 shown in FIGS. 4 and 5 by the user U, the acquisition unit 132 acquires the area information of each of the areas A1 to A6 divided into two or more parts, and the firing information for each piece of limestone arranged in each of the areas A1 to A6. The procedure from when the user U performs the table check to when the area information and the firing information are input is not particularly limited. For example, an operator may write down the results of the table check on a handwritten sheet, and based on this handwritten sheet, the operator, another operator, or an administrator, etc. may input each piece of information into the information processing device 100. For example, when the information processing device 100 is a portable terminal such as a notebook computer or a tablet terminal, the user U can directly select the firing degree, etc. in the plurality of small areas E1 to E6 displayed on the terminal while performing the table check. In S20, the display control unit 138 changes and redisplays the display of the divided area 122E3 based on the firing information acquired by the acquisition unit 132, or displays the firing information in the area firing information display area 122C2, etc.

[0051] In S30, as shown in FIG. 5, the generation unit 134 associates symbols corresponding to the firing information in an array form based on the area information, thereby generating a plurality of numerical arrays as the code information D1. For example, when the symbol "medium 08" is selected for the first divided area E1, the generation unit 134 refers to the firing information master 142 and assigns the numerical code "1" (numerical code corresponding to the firing information) to the first position from the front of the numerical array D1. Similarly, when the symbols "small 08", "〇" (shown as a white area for convenience in FIG. 5), "〇", "〇", "△" are sequentially selected for the small areas E2 to E6, the generation unit 134 refers to the firing information master 142 and assigns the numerical codes "1", "2", "2", "2", "3" to the second to sixth positions from the front of the numerical array D1, respectively. Thereby, the generation unit 134 generates a six-digit numerical array D1 of "1,1,2,2,2,3" based on the firing information acquired by the acquisition unit 132 from the divided area 122E3.

[0052] When "underbaked" is input in any of the small areas E1 to E6, the generation unit 134 associates a symbol such as "medium 8" with the numerical code "1" generated by the input as text data D2. For example, when "medium 08" and "small 08" are input in the first division area E1 and the second division area E2 respectively, the generation unit 134 associates the text data "medium 8" with the first numerical code "1" from the front of the numerical array D1, and associates the text data "small 8" with the second numerical code "1" from the front of the numerical array D1. In this way, the generation unit 134 separately generates a plurality of numerical arrays D1 associated with a plurality of table numbers (numbers of a plurality of inspection ports 76) and for each time series. In FIG. 5, the manner in which the generation unit 134 associates numerical codes and the like for each of the plurality of small areas E1 to E6 is represented by dotted arrows. In S40, the recording unit 136 records the code information (numerical array) D1 associated with the text data D2 in the database 50.

[0053] In S90, the decoding unit 135 decodes the area information and the baking information from the code information D1, for example, by tracing back the process of S30 above. After that, the display control unit 138 combines the area information and the baking information decoded from the code information D1 recorded in the server 50 with the operation information and displays them on the display unit 120 (S90). Specifically, when any of the screens 122, 124, 126 is selected by the user U, on the selected screen, the display control unit 138 displays the area information, the baking information, and the operation information in a predetermined area.

[0054] For example, when the input screen 122 shown in Figure 4 is selected, the display control unit 138 displays area information and firing information in the area firing information display areas 122B2, 122C2, etc., and displays operation information in the operation information display area 122B3, etc. Similarly, when the first display screen 124 shown in Figure 6 is selected, the display control unit 138 displays area information and firing information in the area firing information display area 124A2, the schematic distribution display area 124B2, etc., displays firing information in the graph display area 124C1, etc., and displays operation information in the operation information display areas 124A3, 124B3, etc. Similarly, when the second display screen 126 shown in Figure 7 is selected, the display control unit 138 displays area information and firing information in the firing information display area 126A, etc., displays the arrival time in the time display area 126C2, and displays operation information in the operation information details display area 126C3 and the operation information display area 126D, etc. The display order of each piece of information is not particularly limited, but for example, the display control unit 138 may display area information and firing information, and then display operation information.

[0055] In S100, user U can change the firing conditions of the vertical firing furnace 70 by checking the screens 122, 124, and 126 displayed on the display unit 120 and confirming and understanding the area information, firing information, operation information, etc. For example, if the amount of "under-fired" limestone in a certain raw material passage 75B is greater than a predetermined standard value, user U may increase the flow rate of fuel supplied to that raw material passage 75B. If the firing condition is changed but the degree of limestone firing does not change, user U can know that there is some kind of problem with that raw material passage 75B, etc.

[0056] Furthermore, after processing in S40, the control unit 130 in Figure 2 may determine whether a predetermined first termination command has been entered by the user U's input unit 110. If the first termination command has been entered, it may proceed to processing from S50 onwards. If the first termination command has not been entered, it may return to processing in S10 or S20. In addition, in S90, the control unit 130 may decode and display area information and firing information for each of the multiple code information D1, one by one. Once the decoding and display of all code information D1 has been completed, it may display operation information. Moreover, after processing in S90, the control unit 130 may determine whether a predetermined second termination command has been entered by the user U's input unit 110. If the second termination command has been entered, it may proceed to processing from S100 onwards (returning to S10 after S10 and repeating the subsequent processing). If the second termination command has not been entered, it may return to processing in S80.

[0057] Next, the effects of this embodiment will be described. In this embodiment, a limestone calcination information processing system 10 is shown, comprising: an acquisition unit 132 that acquires area information for each of the two or more divided areas A1 to A6 within a flow channel 75B through which the limestone C calcined in the vertical calcination furnace 70 passes laterally, and calcination information for each limestone C placed in each area; a generation unit 134 that generates code information D1 linking the area information and the calcination information; and a recording unit 136 that records the code information D1 in a database 50.

[0058] With this configuration, information regarding the calcination of limestone C (area information and calcination information) is recorded in the database 50 as code information D1. By using this code information D1, it becomes possible to, for example, view past records, predict the distribution and trends of calcination, and take measures to prevent uneven calcination. It also becomes possible to streamline information sharing and decision-making among workers and managers, and to grasp the latest status of the calcination furnace 70. As a result, (even if information regarding the calcination of limestone C is initially recorded on handwritten paper or similar) it becomes possible to effectively utilize the information regarding the calcination of limestone C.

[0059] Furthermore, the acquisition unit 132 acquires operational information of the vertical firing furnace 70 recorded in the external system 60, and includes a display unit 120 that combines the code information D1 recorded in the database 50 with the operational information and displays it.

[0060] This configuration makes it possible to effectively grasp the detailed status of the calcination furnace 70. Furthermore, by checking operational information and information regarding the calcination of limestone C together, it becomes possible to effectively support the operation of the calcination furnace 70 by predicting the distribution and trends of calcination and considering their causes.

[0061] Furthermore, code information D1 is generated by linking symbols corresponding to firing information in an arrangement based on area information.

[0062] This configuration allows for a practical information processing system 10 for limestone calcination that can perform information processing effectively.

[0063] Furthermore, the limestone calcination information processing system 10 includes an input area 122E that is displayed on the display unit 120 and corresponds to the display position of the input area 122E, and a modification unit 138 that changes the display of the input area 122E. The acquisition unit 132 acquires calcination information input into the input area 122E, and the modification unit 138 changes the display of the input area 122E based on the calcination information acquired by the acquisition unit 132.

[0064] This configuration makes it easier to visually grasp firing information for each area, and facilitates access to past records as described above. Furthermore, it simplifies the process of inputting firing information, reducing the burden of that input work.

[0065] Furthermore, in this embodiment, a limestone calcination information processing program 146 is shown, which causes a computer 100 to execute a process that acquires area information for each of the two or more divided areas A1 to A6 within the flow channel 75B through which the limestone C calcined in the vertical calcination furnace 70 passes in the lateral direction, and calcination information for each limestone C placed in each area, generates code information D1 that links the area information and calcination information, and records the code information D1 in the database 50.

[0066] Furthermore, in this embodiment, a limestone calcination information processing method is described, which involves acquiring area information for each of the two or more divided areas A1 to A6 within the flow channel 75B through which the calcined limestone C passes laterally in the vertical calcination furnace 70, and calcination information for each limestone C placed in each area, generating code information D1 that links the area information and calcination information, and recording the code information D1 in the database 50.

[0067] With this configuration, information regarding the calcination of limestone C (area information and calcination information) is recorded in the database 50 as code information D1. By using this code information D1, it becomes possible to, for example, view past records, predict the distribution and trends of calcination, and take measures to prevent uneven calcination. It also becomes possible to streamline information sharing and decision-making among workers and managers, and to grasp the latest status of the calcination furnace 70. This makes it possible to effectively utilize information regarding the calcination of limestone C.

The recording unit may record the operational information in the database after the acquisition unit has acquired it at such timings, or it may record multiple operational information items in the database at predetermined intervals. Furthermore, in S50, the external system may send the acquired operational information directly to the database and have it recorded in the database. The acquisition unit may acquire operational information in S80 without acquiring it in S60 (without performing the processing in S60).
