Description

  The present invention relates to a measurement history management apparatus, system, method, and program.

  When weighing articles (such as containers containing chemicals) in a chemical plant, human errors such as misreading the weighing value or weighing other articles by mistake may occur. . For this reason, conventionally, in the weighing operation of this kind of article, various information is recorded and managed as follows in order to prevent and detect human error.

  For example, in Patent Document 1, a table is prepared for each production type, and in addition to the article name, article code, weighing results, etc., when a malfunction such as detection of a defective raw material occurs, the lot number of the defective raw material is recorded. Like to do.

  However, what is disclosed in Patent Document 1 is simply to record various information as character data. Such character data can be easily tampered with, and there is a problem that data reliability is poor.

  Also, a plurality of pieces of information on the items to be weighed (for example, the weight value measured by the weighing instrument, the appearance shape of the article container, the display item name, the barcode displayed on the container, the lot number, the date information displayed on the clock, etc.) It is also conceivable that the information is acquired using the information acquisition means, and the operator takes a picture with a still camera or the like for each information acquisition means.

  However, such article information record management has a problem in that work efficiency is poor because each information acquisition means needs to be photographed by a camera. In particular, many chemicals used in chemical plants and the like have volatility and explosive properties, and it is necessary to record and manage information on articles safely and quickly.

  In addition, when managing information acquired by a plurality of information acquisition means for a certain article, there is a risk that an information management error such as a mistake with information on another article may occur. Furthermore, the data to be recorded is character data such as numerical values.For example, when the weighing information of an article is recorded numerically by a spreadsheet software or the like, the data can be easily altered simply by changing the numerical values. There is also a problem that the reliability of recorded and managed information is low.

A display plate 12 can be positioned on the side of the weighing display unit 10. On the display plate 12, the lot number 12a of the article 11 is displayed.

  The camera 2 is an explosion-proof camera (the camera body is a megapixel IP camera), and can capture not only still images but also moving images without being affected even in an environment such as a chemical plant. The camera 2 is installed so that the whole weighing device 1 can be photographed, and an entire image of the photographed weighing device 1 shown in FIG. Yes.

  The switch 3 is operated to transmit a signal to the computer 5 on the management unit 7 side, and to read a still image at the time of operation from a video being shot by the camera 2. By installing it at a position away from the weighing device 1, an image can be safely stored even if the article 11 to be weighed is a dangerous article or the like.

(1-2. Management unit 7)
The computer 5 receives an image captured by the camera 2 and an ON signal from the switch 3, and transmits and receives a control signal. The control unit 14 executes predetermined processing based on the received image. A management display unit 6 (here, a liquid crystal display) having a storage unit 21 capable of storing information (article name, item code) and the like of the item 11 to be weighed and displaying a composite image obtained by the control unit 14 A monitor is used, hereinafter referred to as a liquid crystal monitor).

  In the transmission / reception unit 13, an image captured by the camera 2 and an ON signal input from the switch 3 via the contact interface 15 are input via the switching hub 16.

  The control unit 14 includes a CPU 23 (Central Processing Unit). As shown in FIG. 2, the CPU 23 reads the program 24 from the storage unit 21 and executes the steps of the flowcharts shown in FIGS. 5 and 6. Further, as shown in FIG. 3, the CPU 23 functionally includes an image extraction unit 17 that extracts a specific part from an image received by the transmission / reception unit 13, and an image combination unit 18 that combines the extracted images to obtain a combined image. A display control unit 19 for displaying the obtained composite image on the liquid crystal monitor 6, an electronic signature addition unit 20 for adding an electronic signature to the composite image, and obtained image data and information obtained from the extracted image are stored in the storage unit 21 includes a determination unit 22 that determines whether the information stored in the information 21 is present.

The image extraction unit 17 takes an image of a specific part, that is, the weighing display unit 10, the label 11a attached to the package, and the display plate 12 from the one image shown in FIG. 4A received by the reception unit. Extracted areas. As an image extraction method, if each position of an object photographed by the camera 2 is determined, the determined region may be automatically extracted.

  The liquid crystal monitor 6 and the display control unit 19 are not necessarily required, and may be provided as necessary.

(2. Operation)
Next, the operation of the measurement history management system will be described.

  In the weighing unit 4, an operator places the target article 11 on the weighing table 8 by the weighing device 1 and performs weighing. At this time, the article 11 to be weighed is positioned so that the label attached thereto can be photographed from the camera 2. The weighing result is digitally displayed on the weighing display unit 10 and transmitted to the computer 5 on the management unit 7 side through a communication line. Further, the display plate 12 displays information on the article 11 to be weighed (here, the lot number of the article 11). Then, the switch 3 is operated to transmit that the weighing is in progress to the management unit 7 side.

  In the management unit 7, the control unit 14 performs an information recording process when weighing and a sorting process when shipping the weighed article 11.

  In the information recording process, as shown in the flowchart of FIG. 5, when an input signal at the switch 3 is received (step S1), an ON signal is output to the camera 2 of the weighing unit 4 to start photographing (step S2). In this case, on the computer 5 side, the operator can operate the mouse 5a, move the mouse pointer on the screen, and click at a predetermined position to start shooting with the camera 2.

  The image taken by the camera 2 is the entire weighing unit 4. Then, the image data is received (step S3), and the image data of the weighing display unit 10, the label attached to the package, and the display plate 12 is extracted from the received one image data (step S3). S4). Subsequently, the extracted image data is combined to generate combined image data (step S5). Further, an electronic signature is added to the generated composite image data (step S6). When the addition of the electronic signature is completed, the composite image data is stored in the storage unit 21 (step S7).

  In the information recording process, weighing may be performed with the tag attached to the article 11 to be weighed, and the camera 2 may be used for photographing together with the tag. In this case, the tag image is extracted in step S4, the tag image is included in the composite image data in step S5, and stored in the storage unit 21 in step S7. For the tag, a bar code associated with information (article information) related to the article 11 or an RFID (Radio Frequency IDentification) in which article information is written may be used. Of course, it is also possible to use a tag in which article information is directly printed.

  In step S7, the date and time, the weighing value in the weighing unit 4 and the like may be stored together. Further, among the extracted image data, the weighing value displayed on the weighing display unit 10 and the lot number displayed on the display plate 12 may be stored as character data by character recognition processing.

  In step S7, the barcode printed on the label attached to the article 11 is read out by the barcode recognition process from the extracted image data, and the corresponding article information (article name, article code, etc.) is called. These may be stored together (in this case, the article information corresponding to the barcode needs to be stored in advance in the storage unit 21 or a server (not shown) or the like so that it can be called).

  In this way, the camera 2 takes a picture only once for the entire weighing unit 4, and even if the article 11 to be weighed and photographed is a highly dangerous material or the like, it should be performed quickly and reliably. Can do. The captured image data is transmitted to the computer 5 on the management unit 7 side, where necessary images are extracted, a composite image is generated, an electronic signature is added, and then stored in the storage unit 21. Therefore, it is excellent in preventing tampering.

  In the sorting process, as shown in the flowchart of FIG. 6, first, a bar code is read from a label affixed to an article 11 waiting for shipment by a bar code reader (not shown) connected to the computer 5 (step S11). Then, it is determined whether or not the article information corresponding to the barcode exists in the database stored in advance in the storage unit 21 (step S12).

  If a tag is attached to the article 11, the tag (barcode, RFID, character information, etc.) is read in step S11 instead of reading the barcode, and the database is searched in step S12. You may make it perform. Further, the database may be searched by including both the barcode and the tag, or other readable information. According to this, it becomes possible to further improve the reliability of the sorting process.

  If the corresponding article information does not exist in the database, it is determined that the article 11 is inappropriate, and a warning to that effect is given (step S13). The worker may sort the corresponding articles 11 based on this warning.

  Subsequently, if the corresponding article information exists in the database, whether or not the electronic signature included in the composite image data stored in the storage unit 21 for the article 11 matches the electronic signature stored in advance. Is determined (step S14). This makes it possible to determine whether or not the composite image data has been tampered with. If the electronic signature does not match, the process proceeds to step S13 to give a warning.

  Furthermore, if the composite image data is appropriate, the weighing value is read from the article information retrieved from the database, and it is determined whether or not this weighing value is included in the preset reference range (step S15). If it is not included in the reference range, the process proceeds to step S13 to give a warning, and if it is included in the reference range, it is classified as a proper article 11 for shipment.

  As described above, by determining whether or not the article information exists in the database and whether or not the existing article information is appropriate, it is possible to sort all items that are not problematic. That is, since a plurality of items can be checked not only at the time of weighing but also at the time of shipment, the reliability of the article 11 can be further improved.

  In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

  For example, in the above embodiment, the image synthesis is performed by the computer 5 on the management unit 7 side. However, as shown in FIG. 7, the control unit 14 is also provided on the weighing unit 4 side, and the image synthesis is performed there. Then, it may be transmitted to the management unit 7 side.

  Moreover, in the said embodiment, although it photographed with the camera 2 with the weighing unit 4 provided with the weighing | measuring apparatus 1 which weighs the article | item 11, and memorize | stored the synthesized image, what measured the volume of the article | item 11, etc. Similarly, it is possible to record a composite image with the measuring apparatus.

  Further, in the above embodiment, the photographing by the camera 2 is started by the switch 3 on the weighing unit 4 side, but it may be performed by the operation on the management unit 7 side. For example, the camera 2 may be started by moving the mouse pointer on the liquid crystal monitor 6 by operating the mouse and clicking at a predetermined position.
