Description

  The present invention relates to a filling machine with an explosion-proof camera and a filling system comprising a filling machine with an explosion-proof camera and a management computer.

  Generally, a barcode for identifying a gas cylinder (also referred to as a filling container) is attached to a gas cylinder of LP gas. This bar code is read by a bar code reader and filled with a prescribed gas.

For example, Patent Document 1 (Japanese Patent No. 2845449) reads a bar code of a plurality of filling machines with a single bar code reader by moving the bar code reader with a rail.
Japanese Patent No. 2845449

  However, since Patent Document 1 is a system in which the barcode reader is moved by a rail, a large-scale construction for rail installation is required.

  In addition, since several barcode readers are in charge of one barcode reader, the barcodes of a plurality of filling containers cannot be read at a time, which is inefficient.

  Furthermore, since the bar code is once read by the bar code reader and is filled with the one touch head, the worker has to perform two operations.

  On the other hand, in recent years, in addition to a one-dimensional barcode, a two-dimensional barcode may be attached to a filling container. When a two-dimensional barcode reader is attached, a barcode for a two-dimensional barcode must be used, so two types of barcode readers are eventually required.

  In addition, the barcode may not be read correctly because the filling container is dirty. If the bar code cannot be read, the operator must manually enter the number on the bar code label.

  In addition, it is important to monitor the work site as filling is performed by the workers. For example, a gas leak may occur from the filling container at a later date due to an error in the work process.

  Therefore, it is desirable to have a filling machine system that can identify a bar code or a bar code number or an inscription and manage from filling start to completion of delivery with images without using a bar code reader.

The explosion-proof camera-equipped filling machine is provided with an integrated measuring mechanism and a roller transport base at the bottom, and when placed on the filling container on the roller transport base, a filling hose is connected to the filling port of the filling container, In the filling machine that starts filling by pressing the filling start button on the front operation unit,
The gist of the present invention is to provide an explosion-proof camera attached to the top plate of the filling machine so as to be able to photograph the upper surface of the filling container placed on the roller carrier.

  The filling system of the present invention comprises a measuring mechanism and a roller transport table integrated in the lower part, and when placed on the filling container on the roller transport table, connects a filling hose to the filling port of the filling container, A filling machine that controls filling by pressing a filling start button and a filling end button on the operation unit on the front surface, and a filling amount of liquid or gas to be filled in the filling container is calculated and filled by pressing the filling start button. This is a filling system in which a management computer for managing the filling amount of a filling container is connected via a communication network.

The filling machine is
The top plate is provided with an explosion-proof camera attached so that the upper surface of the filling container of the roller carrier can be photographed,
The management computer is:
A table storing filling container information including a filling container number of the filling container, a tare capacity of the filling container, and customer information;
Each time a video signal for each frame is output from the explosion-proof camera, it is taken in and converted into image data, and the date and time and the filling machine number to which the explosion-proof camera is attached to this image data. Video capture that outputs the added input image data,
Means for determining that the filling container is detected when the weighing mechanism of the filling machine detects weight;
Along with the detection, a bar code label image of the input image data is extracted, and the bar code is decoded to obtain a first number string, which is written on the bar code of the bar code label image. Means for recognizing the second number sequence,
Means for determining whether or not the first number string and the second number string match, and if they match, means for outputting any one number string as a third number string;
When the third number string matches the container management number of the table, the tare capacity corresponding to the container management number is read, and the filling amount into the filling container is obtained from the tare capacity and the weight, And a means for adding the obtained filling amount to filling machine information having the container management number as well as outputting to the filling machine.

As described above, according to the present invention, since the filling container can be photographed from above the filling machine with the explosion-proof camera, the filling of the filling is started by identifying the barcode or the barcode number or the stamp without using the barcode reader. From delivery to completion of delivery can be managed with images.

  FIG. 6 is a schematic configuration diagram of the computer main body 12 of the management computer according to the first embodiment. This schematic configuration diagram is a combination of software and hardware, and the software is executed by a CPU and a memory.

  As shown in FIG. 6, the computer main body 12 includes a camera selection processing unit 50, a video capture unit 52, an image correction unit 55, an image registration unit 57, a barcode recognition unit 58, and a number string recognition unit 59. A synthesizing unit 60, a marking recognition unit 61, a filling amount management unit 62, a recognition selection unit 63, and the like.

  When a photographing instruction (including a filling machine number) is input from the operation unit of the management computer, the camera selection processing unit 50 selects a camera number Ci corresponding to the filling machine number of the photographing instruction from the table 51 and selects the selected camera. The number Ci is output to the controller 10. The controller 10 causes the explosion-proof camera 3 corresponding to the camera number to be supplied with electric power and photographed.

  In addition, the camera selection processing unit 50 outputs the selected camera number Ci to the video capture unit 52.

  The video capture unit 52 operates video capture corresponding to the selected camera number. This operated video capture is referred to as a video capture unit 52.

  The video capture unit 52 digitally converts and captures video signals (with camera numbers) for each frame from the explosion-proof camera 3 and stores them in the buffer memory 54 sequentially. At this time, video data (also referred to as an image frame) is stored with the date and time of the timer 64 added. Further, the video capture unit 52 writes the filling machine number corresponding to the camera number Ci selected by the camera selection processing unit 50 in this image frame.

  For the writing of the date and the filling machine number, it is preferable to provide a frame different from the image frame and write it in this frame.

  The frame and the image frame are preferably stored in the buffer memory 54 in an overlapping manner. This is referred to as an image frame Fi.

  The memory 56 is a working memory. The memory 56 is provided with a first pre-correction image registration file and a first post-correction image registration file. This is to make it possible to compare the post-correction image with the pre-correction image when some incident occurs later.

  The image registration unit 57 determines that this is cylinder detection as the weight detection information (with the filling machine number) of the LPG container 1 is input from the filling machine 2. Then, the latest image frame Fi stored in the buffer memory 54 when the cylinder is detected is taken out (referred to as an image frame Fai at the time of cylinder detection) and stored in the first pre-correction image registration file in the memory 56. At the same time, the image frame Fai when the cylinder is detected is output to the image correction unit 5. In the present embodiment, the buffer memory 54 can store about 20 to 30 image frames.

  In addition, when the filling start information (including the filling machine number) is output from the filling machine 2, the image registration unit 57 sets the latest image frame Fi in the buffer memory 54 as the image frame Fsi at the beginning of filling and stores the first image frame Fi in the memory 56. 1 is stored in the pre-correction image registration file and output to the image correction unit 55. This filling start information is output when an operator presses a filling start button (not shown) of the operation unit of the filling machine 2.

  Further, when the filling end information (including the filling machine number) is output from the filling machine 2, the image registration unit 57 uses the latest image frame Fi in the buffer memory 54 as the first image frame Fei at the end of filling, and stores the first image in the memory 56. Are stored in the pre-correction image registration file and output to the image correction unit 55.

  The image correction unit 55 inputs an image frame Fai at the time of detecting a cylinder from the buffer memory 54, an image frame Fsi at the start of filling, or an image frame Fei at the end of filling (collectively, simply referred to as an uncorrected image frame Fi). Any one of the image frames is converted into a plane rectangular coordinate, which is corrected image frame Hai at the time of detection, corrected image frame Hbi at the start, or corrected image frame Hci at the end (collectively simply referred to as a corrected image frame Hi). ) In the first corrected image registration file in the memory 56.

  The bar code recognition unit 58 outputs from the image registration unit 57 that the image registration unit 57 outputs the image frame Fai at the time of cylinder detection, the image frame Fsi at the start of filling, or the image frame Fei at the end of filling to the image correction unit 55. When notified, the corrected image frame Hai, the corrected image frame Hbi at the start or the corrected image frame Hci at the end of the notified image frame name are allocated from the first corrected image registration file. The barcode label image Bfi is extracted from the corrected image frame Hi.

  Then, the bar and space of the extracted barcode label image Bfi are decoded, converted into a numerical code, and output to the synthesis unit 60.

  When the image string recognition unit 59 is notified from the image registration unit 57 that the image frame Fai at the time of cylinder detection, the image frame Fsi at the start of filling, or the image frame Fei at the end of filling has been output to the image correction unit 55, The corrected image frame Hai at the time of detection, the corrected image frame Hbi at the start time, or the corrected image frame Hci at the end time is allocated from the first corrected image file, and the allocated corrected image frame Hi is allocated. A barcode label image Bfi is extracted from the frame Hi.

  Then, a numeric string of the extracted barcode label image Bfi is extracted, recognized, and output to the synthesis unit 60.

  Furthermore, when the image recognition unit 63 is notified from the image registration unit 57 that the image frame Fai at the time of cylinder detection, the image frame Fsi at the start of filling, or the image frame Fei at the end of filling has been output to the image correction unit 55, The notified corrected image frame Hi is allocated from the first corrected image registration file by allocating the corrected image frame Hai at the time of detection, the corrected image frame Hbi at the start or the corrected image frame Hci at the end from the first corrected image registration file. The stamped portion Kfi is extracted from the subsequent image frame Hi.

  Then, the stamp (symbol and number string) of the extracted stamp part Kfi is extracted, recognized, and output to the synthesizer 60.

  The synthesizing unit 60 reads the selection information (barcode, number string, or stamp) of the recognition selection unit 63, and activates the barcode recognition unit 58 if barcode recognition is performed. If it is a numeric string, the numeric string recognition unit 59 is activated. If it is a stamp, the stamp recognition part 63 will be started.

  Then, the synthesizing unit 60 extracts the corrected image frame Hai at the time of detection, the corrected image frame Hbi at the start or the corrected image frame Hci at the end, and the image before correction, which are extracted and temporarily stored by the image data extraction unit 65. A barcode numeric string Rai or barcode label numeric string Rbi (collectively simply referred to as a numeric string Ri) or imprint Kpi is applied to the detection-time image frame Fai, the start-time image frame Fsi, or the end-time image frame Fei. Write. Then, it outputs the image string to the image management unit 66 and also outputs the numeric string Ri or the marking Kpi to the filling amount management unit 62.

  The image data extraction unit 65 extracts the detection-time image frame Fai, the start-time image frame Fsi, or the end-time image frame Fei from the first pre-correction image registration file in the memory 56, and from the first post-correction image registration file. The corrected image frame Hai at the time of detection, the corrected image frame Hbi at the start time, or the corrected image frame Hci at the end time are extracted.

  Then, once stored, when the composition unit 60 writes the numeric string Ri (barcode numeric string Rai or barcode label numeric string Rbi) or the marking Kpi in the pre-correction and post-correction image frames. Are output to the image management unit.

  An image frame in which the above-described numeric string or stamp Kpi is written is distinguished by adding D.

  The image management unit 66 detects the detection-time image frame DFai, the start-time image frame DFsi or the end-time image frame DFai, the detection-time corrected image frame DHai, the start-time correction image frame DHbi, or the end-time correction. The subsequent image frame DHci is input and associated with it and stored in the memory 67.

  The memory 67 stores a memory 67a in which pre-correction image management information is stored, a memory 67b in which post-correction image management information is stored, a memory 67c in which a detection-time image frame DFai is stored, and a start-time image frame DFsi. , A memory 67e for storing the end-time image frame DFei, a memory 67f for storing the post-detection corrected image frame DHai, a memory 67g for storing the start-time corrected image frame DHbi, and the end And a memory 67h in which the time-corrected image frame DHci is stored.

  The filling amount management unit 62 is connected to the cylinder management table 64. When the weight of the LPG gas is output from the filling machine 2, the filling amount management unit 62 reads management information corresponding to a number string or stamp from the synthesis unit 60, The difference in weight of the LPG gas input from is output to the controller and filled by the filling machine.

  The operation of the filling system using the explosion-proof camera configured as described above will be described below.

  In the present embodiment, the explosion-proof camera 3 is in an operating state, and an image frame (with date and time) from the explosion-proof camera 3 is captured by the video capture unit 52 and written in the buffer memory 54 (full) Then, overwrite from the first one). The engraving will be described later.

  When the LPG gas container 1 is moved from a roller carrier (not shown) to the carrier 12 of the filling machine 2 by an operator, the measuring mechanism 13 of the filling machine 2 measures the weight of the LPG container 1. With this measurement start, the control unit of the filling machine 2 outputs the cylinder detection information (with the filling machine number) to the controller 10 of the management computer 9.

  The controller 10 outputs the cylinder detection information to the computer main body 12. The image registration unit 57 of the computer main body 12 takes out the image frame Fai at the time of cylinder detection stored in the buffer memory 54 in accordance with the input of the cylinder detection information of the LPG container 1 from the filling machine 2, and before the correction of the memory 56. Save to an image file. Further, the image frame Fai at the time of detecting the cylinder is output to the image correction unit 5.

  The image correction unit 5 performs processing described below. FIG. 7 is an explanatory diagram of processing of the image correction unit 5.

  FIG. 7A shows an image frame Fai when the cylinder is detected. As shown in FIG. 7A, the LPG container 1 is a circle when viewed from above, and the stamped portion Kai and the bar code label Bai are also bent images. In this situation, deciphering is not easy. Therefore, as shown in FIG. 7B, the barcode image Bai is taken out and converted into plane coordinates (Bfi). As a result, as shown in FIG. 7B, the thick bar, thin bar, space, etc. of the bar code are aligned in parallel (Bfi). In addition, the numeric string written on the barcode is also a straight line. This is referred to as a post-detection corrected image frame Hai.

  In addition, as shown in FIG. 7A, the stamped portion Kai is also bent. This stamped part Kai is taken out and converted into plane coordinates (kfi). And expand these. That is, the bar code label image and the stamped portion are enlarged in the post-detection corrected image frame Hai.

  In addition, the image correction unit 55 is brilliant (glare) when the LPG container 1 is photographed from above with the explosion-proof camera 3. This “glaring” is removed by smoothing processing, binarization processing, and the like, and the stamped portion is extracted.

  Next, when the barcode recognition unit 58 is notified from the image registration unit 57 that the image frame Fai at the time of detecting the cylinder has been output to the image correction unit 55, the image frame after correction from the corrected image file in the memory 56 is detected. Reserve Hai. Then, the barcode of the barcode image Bfi of the post-correction image frame Hai is decoded to obtain a numeric string Rai.

  Also, when the image string recognizing unit 59 is notified from the image registering unit 57 that the image frame Fai at the time of cylinder detection is output to the image correcting unit 55, the image sequence Hai after detection is corrected from the corrected image file in the memory 56. To reserve. Then, the number string Rbi on the barcode of the barcode image Bfi of the image frame Hai after correction at the time of detection is recognized.

  The synthesizer 60 compares the numeric string Rai above the barcode of the barcode label image Bfi with the numeric string Rbi obtained by decoding the barcode, and determines whether or not they match. If they match, any number string is output to the filling amount management unit 64. In this embodiment, the bar code is decoded and a numeric string Rai is output.

  When it is determined that they do not coincide with each other, the numeric string Rbi on the barcode and the numeric string Rai obtained by decoding the barcode are sent to the filling amount management unit 64.

  As the numeric string Rbi above the barcode and the numeric string Rai obtained by decoding the barcode are sent, the filling amount management unit 62 performs the following processing.

  FIG. 8 is a flowchart for explaining the operation of the filling amount management unit. FIG. 9 is an explanatory diagram for explaining the management table of the memory 64. As shown in FIG. 9, the management table includes a container management number column (Rai or Rbi), a stamp number column, a filling date column, a filling person column, a filling amount column, a tare weight column, a tare capacity column, and a detection image column. It has a record (management information) including a start image field, an end image field, a delivery completion image field, a filling machine number field, and the like.

  A container management number (corresponding to the barcode numeric string Rai or Rbi) is written in advance in the container management number column, and a stamp number is also written in the stamp number column. Further, the tare weight is written in the tare weight column, and the tare capacity is written in the tare capacity column. However, in some cases, the stamp number is not written in the above-described stamp number column.

As shown in FIG. 8, the filling amount management unit 62 monitors whether or not the numeric string Rbi on the barcode and the numeric string Rai obtained by decoding the barcode are inconsistent (S1).
If it is determined in step S1 that there is a mismatch, it is determined whether or not the numeric string Rbi above the mismatched barcode and the numeric string Rai obtained by decoding the barcode are input (S2).

  If it is determined in step S2 that the numeric string Rbi above the barcode and the numeric string Rai obtained by decoding the barcode are input, these are compared with the management table in the memory 64 (S3).

  Then, the synthesizing unit 60 is notified of the numeric string (Rai or Rbi) that matches the container management number Yi in the management table as the numeric string ph (S4).

  Next, the filling amount management unit 62 allocates a record in the management table having the container management number Yi corresponding to the matched numeric string ph (S5).

  Then, the filling amount management unit 62 reads the tare capacity and the tare weight of this record, obtains the filling amount (filling capacity) from the input LPG weight, and sends the obtained filling amount (filling capacity) to the filling machine 2. Output and fill (S6). The filling is started when an on-site worker attaches the one-touch head 15 to the LPG container 1 and presses a filling start button (operation unit).

  Next, the filling date and time, the filling amount, the person-in-charge code, etc. are written in the record of the management table (S7). This person-in-charge code is input in advance by operating the keyboard. Then, it is determined whether or not the process is finished. If the process is not finished, the process returns to step S1 (S8).

  If it is determined in step S1 that they match, the numeric string Rai or Rbi from the synthesis unit is read, and the process proceeds to step S5 (S9).

  That is, a record in the management table having a container management number that matches the numeric string Rai obtained by decoding the bar code is assigned, and the filling amount is obtained and filled.

  Therefore, when the numeric string Rbi on the barcode of the image file from the explosion-proof camera matches the numeric string Rai obtained by decoding the barcode of the barcode recognition unit 58, one of the numeric strings is included. Filling with the filling amount obtained from the size of the cylinder of the record of the management table having a numerical column.

  Further, when the numeric string Rbi on the barcode of the image file from the explosion-proof camera and the numeric string Rai obtained by decoding the barcode of the barcode recognition unit 58 do not match, both are regarded as the numeric string in the management table. The comparison is made, and filling is performed with the filling amount obtained from the size of the cylinder of the record having the numeric string of the matching numeric string ph. The filling amount and filling date / time are written in this record for management.

  Next, processing of the synthesis unit and the image data extraction unit will be described below with reference to the flowchart of FIG. The synthesizing unit 60 determines whether or not the numeric string Rai from the barcode recognition unit 58 and the numeric string Rbi from the numeric string recognition unit 59 are input (S10).

  If it is determined in step S10 that the numeric string Rai and the numeric string Rbi have been input, the numeric string Rai obtained by decoding the barcode is compared with the numeric string Rbi on the barcode to determine whether or not they match ( S11).

  In step S11, when the combining unit 60 determines that they match, the number string Rai, the number string Rbi, or the container management number is added to the uncorrected image frame Fi and the corrected image frame Hi that are temporarily stored in the image data extraction unit 65. Yi is written (S12).

  Then, the image data extraction unit 65 sends the pre-correction image frame DFi and the post-correction image frame DHi in which the numeric string Rai, the numeric string Rbi, or the container management number Yi is written to the image management unit 66 (S14). Next, it is determined whether or not it is finished. If not finished, the process returns to step S1.

  Further, when it is determined in step S11 that they do not match, the numeric string Rai and the numeric string Rbi are output to the filling amount management unit 62, the matched container management number Yi stored in the management table is read, and the process is performed. Return to S12 (S13).

  The image management unit 66 stores the pre-correction image frame DFi and the post-correction image frame DHi in the memory 67. If detected, the detected image frame DFai is stored in the memory 67c. If it is the start time, the start image frame DFsi is stored in the memory 67d. If it is the end, the end image frame DFei is stored in the memory 67c. The memory 67e stores the corrected image frame DHai at the time of detection. The memory 67g stores the corrected image frame DHbi at the start. The memory 67h stores the corrected image frame DHci at the end.

  The image management unit 66 reads the container management number, stamp number, date, time, and filling machine number written in the uncorrected image frame DFi and the corrected image frame DHi, and the uncorrected image shown in FIG. Management information and corrected image management information are generated and stored. The pre-correction image management information is stored in the memory 67a. The corrected image management information is stored in the memory 67b.

  As shown in FIG. 11, the above-mentioned image management information before correction and image management information after correction include the container management number, the stamp number, the year / month / day / time, the filling machine number, the storage address of the detection image frame DFai, and the start image frame Dsi. The storage address and the storage address of the filling end image frame DFei, the storage address of the detection corrected image frame DHai, the storage address of the start corrected image frame DHsi, the storage address of the end corrected image frame DHei, and the like.

  That is, in the memory 67, the container management number, the stamp number, the date and time, the filling machine number, the detection image frame DFai, the start image frame Dsi, the filling end image frame DFei, the detection corrected image frame DHai, and the start corrected image Image management information in which the frame DHsi and the post-end-correction image frame DHei are associated with each other is stored.

  Accordingly, the detection image, the start image, and the end image when the gas cylinder is detected from the image management information and the corrected images (detection image, start image, end image) are managed. The desired image can be easily obtained from the table and the presence or absence of abnormality can be known.

  The image management unit 66 notifies the filling amount management unit 62a that the image management information has been created. At this time, the storage address of each image frame is notified.

  Each time the creation of the image management information is notified, the filling amount management unit 62 reads the storage address of the detected image, the storage address of the start image, and the storage address of the end image corresponding to the container management number Yi of the image management information, This is written in the detected image column, start image column, and end image column of FIG. In addition, the date of the image management information is written in the year / month / time column.

  Therefore, by searching the management table shown in FIG. 9, the detection image, the start image, and the end image corresponding to the container management number can be extracted. The delivery completion image in FIG. 9 will be described in the second embodiment.

<Embodiment 2>
In the second embodiment, the image of the LPG container 1 is managed in relation to the numeric string Ri recognized by the explosion-proof camera from the start of filling to the delivery image (before and after replacement).

  FIG. 12 is a schematic configuration diagram of a system according to the second embodiment. As shown in FIG. 12, the camera-equipped mobile phone 41 (or digital camera) images the LPG container 1 and transmits the captured image to the management computer 9 via the communication network, from the filling start image to the delivery image. Manage all at once.

  In order to realize this, the aforementioned management computer 9 has the configuration shown in FIG. In FIG. 13, the description of the same components as those in FIG. 1 is omitted. As shown in FIG. 13, an image transmission / reception unit 131 is provided.

To send. Further, the image extraction unit 65 outputs the post-modification upper image frame DGuai after modification and the upper image frame DMbi after modification after modification from the second modified image file to the image management unit 66.

  The image management unit 66 includes the pre-replacement image frame Gai, the pre-replacement top image frame Gai, the post-replacement image frame Mai, the post-replacement top image frame Mbi, the post-replacement top surface image frame DGuii, and the post-repair image frame Gai from the image data extraction unit 65. After the replacement, the upper image frame DMbi is stored in the memory 67.

  In the present embodiment, the pre-replacement image frame Gai is stored in the memory 67j, the pre-replacement upper image frame Gai is stored in the memory 67k, the post-replacement image frame Mai is stored in the memory 67l, and the post-replacement upper image frame Mbi is stored in the memory 67l. It is stored in the memory 67k, the post-replacement upper image frame DGuai before replacement is stored in the memory 67n, and the post-correction upper image frame DMbi after replacement is stored in the memory 67p.

  The filling management unit 62a reads the container number of Rai or Rbi from the management table and sends it to the image transmission / reception unit 131 to output a transmission instruction for sending the attachment input screen 20a or the post-replacement input screen 20b. A mail address is added to the transmission instruction.

  That is, as shown in FIGS. 14 to 16, the image frame from the container detection to the completion of delivery (before and after replacement) is stored in the memory 67 of the image management unit 66 in association with each other.

  Therefore, if there is an accident at a later date, it will be possible to know what time the accident occurred due to the work.
