In FIG. 2, the block diagram which shows the structure of the inspection and repair management system of the coke oven body which concerns on embodiment of this invention is shown.

In the present invention, the inspection and repair work records of the current coke furnace body are managed by the furnace body management server 1 from the past, and the furnace body changes immediately from the inspection and repair records for each kiln inputted to the furnace body management server 1 as needed.・ Trends are detected, and this information can be shared among workers at the work site and other coke oven operation managers.

The inspection and repair records for each kiln that are input to the furnace body management server 1 as needed are recorded using the PDA terminal 2 and the electronic pen 3 that are carried by an operator who performs the inspection and repair work on site.

The inspection and repair work of the coke oven is carried out in units of kilns, for example, for the 21 parts shown in FIG. In terms of the furnace, the inlet frame (1), the inlet lid (2), the flue metal (3), the furnace top tile (4), the riser in general (5), the riser lining (6), the brick in the inlet The joint (7), the bend (8), and the tie rod (9) are targeted. In addition, in terms of the furnace bottom, the door frame (10), door frame mounting hardware (11), furnace port outer joint (12), furnace port inner joint (13), furnace port protection hardware (14), furnace lid (15), mirror Brick repair (16), carbonization chamber wall (17), and bellows repair (18) are targeted.

As shown in FIG. 2, the furnace body management server 1 acquires information input from the electronic pen 3 as wall surface management information 4, and acquires information input from the PDA terminal 2 as furnace body management information 5.

Information

4, 5 acquired by the furnace body management server 1 is stored in the input information storage unit 1a. These pieces of

information

4 and 5 are processed by the information processing unit 1b to be furnace body chart information 6, periodic inspection guidance information 7, repair kiln guidance information 8, repair life evaluation information 9, and preventive maintenance guidance information 10. Each piece of processed information 6 to 10 is stored in the storage unit 1c of the furnace body management server 1.

Hereinafter, input means for the wall surface management information 4 and the furnace body management information 5 acquired by the furnace body management server 1 will be described.

(Wall management information input means)
In this embodiment, a handwritten image is input on an electronic special pen that is a dedicated handwriting input means on a dedicated special sheet using the Anoto (registered trademark) technology (also referred to as the Anoto function), and the handwritten content is electronically stored. A technique that uses a handwriting input method that converts the data into a server device is used.

FIG. 4 shows a configuration example of the electronic pen 3. The electronic pen 3 includes a pen unit 14, a pressure sensitive unit 15, a camera unit 16, a processing unit 17, a storage unit 18, a transmission unit 19, and the like. When an operator performs handwriting input on the dedicated paper 13 compatible with the electronic pen using the electronic pen 3, the electronic pen 3 can sequentially acquire the contents entered on the paper 13.

The pen unit 14 records ink on the paper 13 by discharging ink when the pen tip is moved against the paper 13. The pressure sensing unit 15 includes a piezoelectric element, is fixed to the pen unit 14, and detects a force or pressure applied to the pen unit 14. Since the pen unit 14 is pressed against the paper 13 while the pen unit 14 is filling in the paper 13, the pressure-sensitive unit 15 detects that the electronic pen 3 is handwritten. The camera unit 16 reads the dot pattern printed on the paper surface of the paper 13 around the tip of the pen unit 14 by infrared rays.

A special dot pattern printed with ink containing carbon is formed on the paper 13. The area where the dot pattern is formed becomes an input area where the user inputs information using the electronic pen 3. Each dot of the dot pattern printed in the input area is two-dimensionally arranged and printed so that its position can be specified. When handwritten input is performed on the paper 13 with the electronic pen 3, it is first detected by the pressure sensing unit 15 that handwriting is input with the electronic pen 3. While it is detected by the pressure sensing unit 15 that the handwriting is input, the camera unit 16 reads the dot pattern on the paper 13. Thus, the electronic pen 3 can acquire the locus of the tip of the pen unit 14 when handwritten input is performed, and can acquire the content entered on the paper 13.

In the present embodiment, as shown in FIG. 5, a wall surface image 52 is printed on the paper 13, and the deteriorated part range and the repaired part range can be input by handwriting on the wall surface image 52 using the electronic pen 3 ( (See handwritten portion 51 in FIG. 5). Although the wall surface image 52 is simply illustrated in FIG. 5, the state in which fire bricks are actually stacked, the size of each part, and the like are described.

Also, on the paper 13, the inspection / repair designation column 53, the target kiln, the implementation date, the operator's name column 54, the damage location inspection result column 55 (brick drilling, brick loss, brick crack, etc. Items), repair content column 56 (repair method, furnace exit, repair start and end times, door closing time, materials used), repair result column 57 (repair scope, repair status, other special notes), and comment column 58 and the like are printed, and each column can be input by handwriting with the electronic pen 3. In the illustrated paper 13, a field (for example, fields 55 to 57 and other special notes and comments field 58) in which a comment or the like can be freely described with the electronic pen 3 and options are printed in advance. (For example, inspection / repair designation column 53, damaged portion inspection result column 55 with / without brick perforation, presence / absence of brick defect, presence / absence of brick crack, etc.).

In this way, the inspection and repair information entered on the paper 13 by the electronic pen 3 is converted into electronic data and becomes the wall surface management information 4. In addition to the information described above, a lead line or the like may be included.

Further, the electronic pen 3 includes the degree of damage obtained by evaluating the degree of damage of the wall surface in six levels from 0 to 5 in the wall surface management information 4 to be converted into electronic data. The degree of damage is determined based on the damage value automatically calculated from the data input with the electronic pen 3 using the formula “damage value = (unrepaired damaged part area) ÷ (total carbonization chamber area) × 100”. Is done. In this embodiment, “damage value> 9” indicates a damage degree of 5 points, “damage value: 7 to 9” indicates a damage degree of 4 points, “damage value: 5 to 7” indicates a damage degree of 3 points, and “damage value: 3” “5 to 5” is defined as a damage degree of 2 points, “damage value: 1 to 3” is defined as a damage degree of 1 point, and “damage value: 0 to 1” is defined as a damage degree of 0 point. For example, it is assumed that an unrepaired damaged part is recorded as a handwritten part 51 shown in FIG. 5 for a carbonization chamber having a total area S = 68 m ² . In this case, the damaged part area (S ′) is automatically calculated from the handwriting of the electronic pen 3, and the damage degree is determined as 2 points from the damage value = S ′ / S × 100 (%) = 3.2. Here, it has been described that the damage degree is obtained with the electronic pen 3, but the damage degree may be obtained with the furnace body management server 1.

Note that each sheet 13 has a sheet ID. The electronic pen 3 can acquire the paper ID by reading the dot pattern. Therefore, even when additional recording is made on the same sheet 13, data indicating the contents previously entered can be easily specified, and the additional recording data can be easily associated with this data.

The processing unit 17 performs processing such as data compression processing and adding the ID of the electronic pen 3 to the data read by the camera unit 16. The storage unit 18 stores data processed by the processing unit 17. The transmission unit 19 wirelessly transmits the information stored in the storage unit 18 to the furnace body management server 1 by Bluetooth (registered trademark). The electronic pen 3 has a USB interface (not shown), and can output data to the outside through a USB cable.

The operator can select the target region 61, call up a recording screen (FIG. 7), and perform work recording.

FIG. 7 shows a recording screen that is called when “rising pipe” is selected on the work recording input menu screen of FIG. On the recording screen of the PDA terminal 2, an inspection / repair designation 71, a target furnace and kiln 72, an implementation date 73, and a comment 74 can be input. Further, the damage degree 75, the illustration 76, and the damage degree table 77 can be selected and input. Of each part of the furnace body, the degree of deterioration related to the part in which the damage generated at the part directly affects the life of the furnace body is evaluated as a numerical degree of damage. The quantification of the damage degree can be objectively performed by appropriately selecting from damage level levels that are defined in advance so as to be selectable in order to digitize the visual evaluation result of the worker. For example, in the “rising pipe” shown in FIG. 7, the damage level is 5 points for “having a hole”, 4 points for “having crack ignition”, and 3 points for “having crack gas leak”. It is specified to be selectable. On the other hand, the degree of deterioration related to a part that hardly affects the life of the furnace body even if the part is damaged is evaluated as “damaged” or “no damage”.
