Description

Technical Field

[0001] The present invention relates to an inspection system.

Background Art

[0002] Conventionally, techniques for inspecting the water quality of storage tanks, fish baskets, pools, etc. or components such as urine using reagents have been known.

[0003] In many cases, a portable inspection device is used for this inspection. For example, a portable information terminal capable of communicating with a measuring instrument for measuring the concentration of a substance in Patent Document 1 (Japanese Patent No. 6720465) includes a data acquisition unit that acquires a plurality of calibration curve data, and a plurality of substances corresponding to each of the acquired plurality of calibration curve data. A plurality of measurement items are displayed on the display screen so that the user can select a measurement item corresponding to the actual measurement target from among the measurement items indicating the measurement items. Then, the calibration curve data corresponding to the measurement item selected by the user is transmitted to the measuring instrument using wireless communication.

[0004] Further, Patent Document 2 (Japanese Unexamined Patent Application Publication No. 2011-113425) discloses a water sampling container with an RFID tag, an information terminal device including a tag reader and a tag writer for reading and writing the RFID tag and a GPS receiver, a water sampling information input means for inputting water sampling information to the information terminal device, an inspection information input means for inputting inspection information, a reading means for reading the RFID tag, a water quality information database for recording the water sampling information and the inspection information read by the reading means, and a water quality information search means for searching for water quality information designated by the user from the water quality information database and the map database.

[0005] And it is disclosed that water sampling information in which the position information and time information from the GPS receiver are associated with various information related to water sampling input to the information terminal device is written to the RFID tag by the tag writer.

[0006] On the one hand, the water quality monitoring system of Patent Document 3 (Japanese Patent Application Laid-Open No. 2005-250557) is a water quality monitoring system that transmits water quality data measured by a water quality measuring device (measurement side) to a management department (management side) via the Internet for analysis and monitors the water quality. The measurement side is disclosed to mail the measurement data obtained by the water quality inspection equipment to the server on the management side.

[0007] And the management side receives the above measurement data, analyzes the measurement data, creates a database, and mails predetermined water quality data and / or alert information to the client's mobile terminal, and mails predetermined data to the communication terminal in the water quality measuring device according to a command from the client's PC. The client is disclosed to monitor the water quality based on the water quality data and / or alert information displayed on the screen of the above mobile terminal.

Summary of the Invention

Problems to be Solved by the Invention

[0009] However, conventional inspection medium reagents, test papers, and handy-type inspection devices such as those in Patent Document 1 require human judgment for linking with the inspection target and transcription work.

[0010] In addition, conventional inspection medium reagents, test papers, and handy-type inspection devices did not enforce the inspection location. For this reason, it was possible to commit fraud without moving to the actual location. In addition, there were also those who omitted work or committed fraud based on arbitrary judgments, which became a social problem.

[0011] In the conventional inspection, sampling and storage of samples may be performed, but it was left to the work ethic of the operator based on the theory of the goodness of human nature. However, there have been cases of fraud such as replacing samples arbitrarily, substituting inspection targets, and rewriting different data during transcription, which has become a social problem.

[0012] Currently in Japan, the declining birthrate and aging population are progressing, and chronic labor shortages have become a social problem. Therefore, efficiency and low cost are required for labor work. On the other hand, for ensuring the safety and reliability of products and environmental considerations, related inspections are also required simultaneously, resulting in a large burden on work and an increase in costs.

[0013] Furthermore, current inspection work is often not efficient, and in particular, there are many cases where linking and transcription of inspection work rely on manual operations. There is also a method of introducing equipment fixed-installed at the inspection location, but when there are many applicable locations, the introduction cost and maintenance cost become high, and in many cases, the introduction cannot be carried out, and there are still many operators who continue with manual work.

[0014] Also, Patent Document 2 assumes the need for a water sampling bottle and GPS, uses an RFID tag for linking the water sampling bottle, and obtains location information from GPS. For this reason, the device itself cannot be constructed inexpensively and cannot be used indoors.

[0015] That is, in the case of land-based aquaculture where multiple storage tanks are operated indoors or in a closed environment such as equipment in a factory, the location cannot be specified. Furthermore, since Patent Document 3 analyzes measurement data by the administrator, as a result, it leads to a large burden on work and an increase in costs.

[0016] The present invention has been made in view of the above problems, and aims to obtain a handy type inspection device and an inspection system that can address such social problems, improve the work efficiency of inspection, and improve fraud prevention.

Means for Solving the Problems

[0017] The present invention has been made in view of the above problems, and is a portable inspection system for inspecting an inspection medium stored in a storage tank, the inspection information acquisition unit for acquiring inspection information based on the execution of the inspection of the inspection medium in the storage tank, a wireless tag storing tag information including storage tank information of the storage tank installed in the storage tank, and an association unit for reading the inspection information and the tag information and associating the inspection information with the tag information.

[0018] (2) In the above (1), a handy inspection device with a sensor is provided, and a sensor for inspecting the inspection medium and outputting the inspection information is connected to the handy inspection device with a sensor. Further, the information of the wireless tag is read, and the tag information and the inspection information from the sensor are associated and stored in a storage unit.

[0019] (3) In the above (1), a test strip reading inspection device is provided. The test strip reading inspection device represents test strip information of a test strip for inspecting the inspection medium in a two-dimensional code and registers it in a storage unit, recognizes the output two-dimensional code, reads the tag information of the wireless tag, and associates the two-dimensional code, the test strip information after the test, and the read tag information and stores them in the storage unit.

[0020] (4) In the above (1), the storage tank information includes the position information of the storage tank and the biological information in the storage tank.

[0021] (5) In the above (1) or (2), an imaging device is connected to the handy inspection device with a sensor, the situation of the inspection is imaged, and it is associated with the tag information.

[0022] (6) In the above (1) or (2), an anti-tampering label printing device is provided, and a label printed from the anti-tampering label printing device is attached to the storage tank.

[0023] (7) In the above (3), the test strip and the two-dimensional code are installed on a combination pedestal, and the combination pedestal is configured to be detachable from the test strip reading inspection device.

Advantages of the Invention

[0024] By combining a short-range wireless tag and an inspection device, labor savings can be achieved. By installing a short-range wireless tag on the inspection target in advance and approaching the inspection target to conduct the inspection during the inspection, the inspection target can be identified, enabling automatic linking of the location and inspection data, and labor savings compared to manual operations.

[0025] By combining a short-range wireless tag and an inspection device, it is possible to enhance the anti-fraud effect. By installing a short-range wireless tag on a storage tank or the like that is the inspection target in advance, since the inspection must be carried out at that location, the deterrent effect such as anti-fraud can be enhanced.

[0026] By combining a short-range wireless tag, an inspection device, and a camera to record the actual operation, the anti-fraud effect can be enhanced. By recording the actual operation from the perspective of the operator with a camera connected to the inspection device and linking the location, inspection, and image, the legitimacy of the operation can be enhanced, and anti-fraud can be further enhanced compared to the case of only the wireless tag.

[0027] By combining a short-range wireless tag (RFID), a device, a camera, and an anti-fraud label, etc., to record the actual operation as an image or video, the legitimacy and re-verification of the sample can be enabled. By recording the actual operation from the perspective of the operator, by linking the location, inspection machine, image, and sample, the legitimacy of the sample can be enhanced.

Embodiments for Carrying Out the Invention

[0029] Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. In this example, descriptions of already known technologies are omitted. Also, what is illustrated is a structure and method for embodying the technical idea of the invention, and the technical idea of the present invention is not limited to the following. The technical idea of the present invention can be variously modified within the scope of the matters described in the claims. In particular, it should be noted that the drawings are schematic and different from the actual ones. The embodiments show the most preferred forms of the invention, and the invention is not limited thereto. In this example, the inspection medium refers to liquids, soil, fresh concrete, etc. In this example, liquids will be described as an example.

[0030] Refer to FIG. 1. A portable inspection system 1 inspects an inspection medium (in this example, a liquid) stored in a storage tank (storage tanks A to D) 10. And based on the execution of the inspection of the inspection medium in the storage tank 10, an inspection information acquisition unit that acquires inspection information, a wireless tag that stores tag information including the storage tank information of the storage tank 10 installed in the storage tank 10, and an association unit (214, 514) that reads the inspection information and the tag information and associates the inspection information with the tag information.

[0031] Specifically, the inspection system 1 includes a management device 2, a communication device 3, a communication station 4, a cloud 5, an imaging device (a camera from the operator's perspective) 6, and a printing device 8 that prints a label (which may be a label on which the information of the storage tank 10 is described) 7. The management device 2 manages the entire inspection system 1. The communication device 3 communicates with external devices. The communication station 4 is a relay station for communication. The cloud 5 is a server having a large-capacity storage unit. The imaging device 6 is worn by the operator and captures the working situation. The label is a label 7 that proves whether a predetermined operation has been performed. The printing device 8 prints the acquired information on the label 7.

[0032] The management device 2 includes a control device (such as a CPU, a memory, a Raspberry Pi, etc., and may include a communication device) 2a, an inspection information acquisition unit (for example, a sensor 21 that inspects PH, oxygen, etc.) 2b, an association device (a short-range wireless device, a camera for code scanning) 2c, and a storage area 2d. The control device 2a performs computer control and includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory). The inspection information acquisition unit 2b is, for example, a sensor or the like that acquires information on inspecting PH, oxygen, etc. The association device 2c is a short-range wireless device or a camera for code scanning that reads the information included in the wireless tag 12 or a QR code (registered trademark). That is, when the operator approaches the storage tank 10, the information of the wireless tag 12 can be automatically read. And the information of the read storage tank 10 is associated with the inspection information acquired by the sensor.

[0033] The wireless tag is preferably an RFID tag. The linking method may be, in addition to wireless tags such as RFID, a position sensor such as GPS, a code (barcode, QR code (registered trademark), unique other), etc. To ensure verifiability and legitimacy, an image or video during the operation is taken. There is also pasting an anti-tampering label, etc.

[0034] In the following, <Embodiment 1> will be described as using a handy type inspection device with a sensor for detecting RFID. <Embodiment 2> will be described as using a test paper reading inspection device (handy type).

[0035] <Embodiment 1> Embodiment 1 has a configuration in which position information of the storage tank 10 and biological information in the storage tank 10 are stored and acquired in, for example, an RFID tag 12 or a two-dimensional code (QR code (registered trademark)) attached to the storage tank (storage tank in which the inspection medium is stored) 10. That is, it can be used indoors and outdoors densely. For example, by fixing the RFID tag 12 so that it cannot be easily moved to the storage tank or the inspection table, it is possible to link the storage tank 10 at a specific location regardless of indoors or outdoors with the inspection result.

[0036] In particular, since the range of the wireless tag 12 can be selected as a plurality (within a few centimeters, within dozens of centimeters, within several meters), it is possible to accurately identify the location even when the storage tanks 10 are dense.

[0037] On the other hand, in the case of an operation relying on a bottle for water sampling, since it is possible to swap before and after water sampling, etc., in order to prevent fraud, a photo is taken with an imaging device (digital camera, etc.), and the operation video is associated with the acquired data. This makes it possible to enhance the anti-tampering effect even more.

[0038] Figure 2 is a schematic configuration diagram of the handy type inspection device 22 with a sensor according to the first embodiment. A sensor 21 is connected to this handy type inspection device 22 with a sensor via a cable 23. The handy type inspection device 22 with a sensor, the imaging device 6 worn by the operator, and the printing device 8 for printing the anti-tampering label 7 etc. are configured to be communicable via a wireless LAN.

[0039] Furthermore, a two-dimensional code or a wireless tag 12 (RFID: Radio Frequency Identification) is attached to the storage tanks (storage tanks A to D) 10. In this example, the case where the wireless tag 12 is attached will be described. The wireless tag 12 stores tag information including a tag number, the position information of the storage tank 10, the name of the organism in the storage tank 10, the owner, etc.

[0040] Refer to Figure 3. A sensor data acquisition unit 202 that reads the acquired data from the sensor 21, an RFID reading unit 204 that stores the information read when approaching the RFID 12 in the storage unit 218, a measurement data recognition unit 206 that recognizes the data acquired from the sensor 21, a screen display unit 208 that performs association display etc. of the measurement information and the information acquired from the RFID 12, an input unit (keyboard etc.) 210 for the operator to perform input processing, a transmission / reception unit 212 that wirelessly transmits and receives the read data to / from the server, an association unit 214 that stores the inspection information (inspection data) of the storage tank 10 and the information of the storage tank 10 stored in the REID in the association storage unit 218, a camera image acquisition unit 216 that stores the image captured by the imaging device 6 attached to the operator in the storage unit 218, a storage unit 218 that stores various information, etc. These are programs of a computer (CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory)).

[0041] The aforementioned measurement data recognition unit 206 has measurement functions such as pH (hydrogen ion concentration), ORP (oxidation-reduction potential), DO (dissolved oxygen), EC (electrical conductivity), water temperature, salt concentration, ammonia, turbidity, etc. (collectively also referred to as components).

[0042] Also, when an operator wears the imaging device 6 (preferably a head camera) and carries the handy inspection device 22 with a sensor and approaches the storage tank 10, the image is stored in the storage unit 218. On the other hand, since the wireless tag 12 for the storage tank 10 side is attached to the storage tank 10, information about the storage tank 10 (position, organisms in the storage tank, storage tank number, etc.) is detected by the RFID reading unit 204 of the handy inspection device 22 with a sensor and stored in the storage unit 218 (with date, year, month, day, hour, and minute).

[0043] On the other hand, the operator operates the input unit 210 to input the operator code. In addition, a one-dimensional barcode or two-dimensional code label indicating the operator code, facility code, etc. may be attached to the operator's clothes, and this label may be read.

[0044] The transmission / reception unit 212 transmits this operator code to a server (which stores the operator's name, operator code, years of experience, past work history, etc.) and receives verification. The storage tank ID of the storage tank 10 is recorded in advance in the wireless tag 12 (RFID) of the storage tank 10. In addition, instead of the wireless tag 12 (RFID), a two-dimensional code (storage tank ID, position information, organisms in the storage tank, etc.) may be read by the code reading unit. These data are stored in the storage unit 218.

[0045] Then, when the sensor 21 is placed in the storage tank 10, sensor data is acquired by the sensor data acquisition unit 202 of the handy inspection device 22 with a sensor and stored in the storage unit 218.

[0046] The measurement data recognition unit 206 analyzes pH (hydrogen ion concentration), ORP (oxidation-reduction potential), DO (dissolved oxygen), EC (electrical conductivity), water temperature, salinity concentration, ammonia, turbidity, etc., and the screen display unit 208 displays them as numerical values, etc.

[0047] These data (operator code, position information, measurement data) are transmitted by the transmission / reception unit 212 to the server via a wireless communication network (e.g., wireless LAN).

[0048] In addition, a work image is acquired by an imaging device (such as a camera) 6 of an operator, and this is stored as an image in a storage unit 218 by a camera image acquisition unit 216, and is transmitted to a server together with the above-mentioned linked information (such as a camera number, position information, operator code, date, year, month, day, and time) by a transmission / reception unit 212.

[0049] Therefore, since the association with the inspection target can be automatically performed, chronic manpower shortages can be eliminated and costs can be reduced. In addition, fraud cannot be committed without moving to the actual location. Referring to FIG. 1, as a result of any determination in the management device 2, the inspection target is determined to be the storage tank B, and as a result of other determinations, the inspection target is determined to be the storage tank D.

[0050] It is also impossible to omit work or commit fraud by arbitrary judgment. Furthermore, since GPS is not used, the device itself can be constructed at low cost, and it can be acquired with position information regardless of whether it is indoors or outdoors. That is, the work position and work situation can be acquired at any location.

[0051] In the above description, the wireless tag 12 is described as being provided in the storage tank 10, but the wireless tag 12 may be provided in the handy type inspection device 22 with a sensor, and an RFID reader / writer unit (waterproof processing) may be provided on the storage tank 10 side. In this case, it is preferable to provide the RFID reader / writer unit of the storage tank 10 with wireless transmission / reception means (for example, Wi-Fi) and to provide a router, for example, near the storage tank.

[0052] <Embodiment 2> FIG. 4 is a schematic configuration diagram of a test paper reading inspection device 50 according to the present embodiment. Description of the same reference numerals as in FIG. 2 is omitted. It has an imaging device (such as a camera) 6 worn by an operator, a wireless communication network (for example, wireless LAN), a server, and a printing device 8. Therefore, these devices can communicate wirelessly.

[0053] As shown in FIG. 4, the test strip reading and inspection device 50 is a portable, cup-shaped test strip reading and inspection device 50 (handheld type) for inspecting the test strip 55. Further, when this test strip reading and inspection device 50 approaches the wireless tag 12, it reads the information of the wireless tag 12.

[0054] The test strip reading and inspection device 50 is provided with a switch, a screen display unit 508, etc. on the upper surface of the main body. Further, an internal imaging device is provided inside. An insertion port is provided on the lower side surface of the test strip reading and inspection device 50. The combination pedestal 54a can be inserted through the insertion port.

[0055] The test strip 55 placed on the combination pedestal 54a is inserted into the insertion port, and the internal imaging device (camera, etc.) of the test strip reading and inspection device 50 images the test strip 55 arranged on the combination pedestal 54a inserted into the insertion port. Further, a two-dimensional code (QR code (registered trademark)) 52 is attached to the combination pedestal 54a. And it is configured to recognize this two-dimensional code 52. The two-dimensional code 52 contains the information of the test strip 55.

[0056] On the other hand, also in the second embodiment, the operator wears an imaging device (head camera, etc.) 6, and the position information and the number of the test strip reading and inspection device 50 can be obtained in the same manner as in the first embodiment, and the working condition is photographed by the imaging device (head camera, etc.) 6. Therefore, fraud can be prevented, the device itself can be constructed inexpensively, and it can be obtained with position information regardless of indoors or outdoors. That is, the working position and the working condition can be obtained at any location.

[0057] Refer to Fig. 5. It has an image data acquisition unit 502 that reads the acquired data from the internal imaging device, an RFID reader 504 that acquires information by approaching an RFID, a measurement data recognition unit 506 that recognizes the measurement data measured with the test paper 55 and stores it in the storage unit 516, a screen display unit 508, an input unit 510, a transceiver unit 512 that wirelessly transmits and receives the read data to and from a personal computer, an association unit 514 that associates the measurement data with the information acquired by approaching an RFID, a storage unit 516 that stores various information, etc. These are programs of a computer (CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory)).

[0058] Refer to Fig. 6. In the storage unit 516, the reference definitions (such as Dipin60 manufactured by Company A) of each test paper 55 and the extraction definitions (such as Dipin60 manufactured by Company A) of the test paper 55 are registered. Each of these pieces of information is encoded as a two-dimensional code (QR code (registered trademark)) 52.

[0059] Refer to Fig. 7. As a preliminary preparation, a two-dimensional code label 53 corresponding to each test paper 55 is printed from a printing device. That is, a two-dimensional code label is printed for each type of test paper 55.

[0060] Refer to Fig. 8. The two-dimensional code label 53 corresponding to each test paper 55 is pasted on each combination pedestal 54a, 54b ···. As a result, several combination pedestals for each test paper are prepared each time, so there is no need to print the two-dimensional code label 53 corresponding to each test paper 55 from the printing device each time. On the other hand, the pedestal for combination with an RFID is created dedicatedly for each test paper, and grooves are set so that the test paper does not shift even when alone.

[0061] Refer to Fig. 9. Since this test paper reading and inspection device 50 can utilize a battery and Wi-Fi, etc., it has portability. When approaching an RFID, the target aquarium can be identified (e.g., the flounder No. 1 aquarium, etc.).

[0062] Refer to Fig. 10. When the test paper 55 is placed in a liquid, it is possible to test, for example, six types of water quality (NO3, NO2, CL2, GH, KH, pH). Also, since different types of test papers can be defined respectively, it is possible to flexibly change or add test items.

[0063] Refer to Fig. 11. Place the test paper 55 after the test on the combined pedestal 54a with the two-dimensional code 52 pasted on it.

[0064] Refer to Figs. 12 and 13. Insert the combined pedestal 54a with the two-dimensional code 52 pasted and the test paper 55 after the test installed into the test paper reading and inspection device 50, and operate the button while checking the screen display unit 508 to perform inspection and storage.

[0065] Although the embodiments have been described in detail above, they are not limited to specific embodiments, and various modifications and changes are possible within the scope described in the claims. Also, it is possible to combine all or a plurality of the components of the above-described embodiments.
