Description

Technical Field

[0001] The present invention relates to the technical field of metrological verification (calibration), and particularly to a self-service inspection reporting and information collection method and system for pressure gauge metrological verification. Background Art

[0002] The pointer type pressure gauge (hereinafter referred to as: pressure gauge) is widely used for measuring the gauge pressure of gas or liquid media due to its simple structure and strong anti-interference ability; it is also one of the indispensable safety accessories for pressure-bearing equipment and has irreplaceability. After long-term use, the measurement accuracy of the pressure gauge may decline, so it is necessary to regularly detect its measurement accuracy to determine whether it is qualified; if it is qualified, it can continue to be used, otherwise it needs to be repaired or scrapped. The total amount of pressure gauges used in various industries is very large, and due to being included in the mandatory verification management by the state, its inspection volume is also very huge; among the total inspection volume of measuring instruments in metrological inspection institutions at all levels in China, the proportion of pressure gauges is always at the top. Therefore, continuously improving the work efficiency and work quality of pressure gauge verification (calibration) is an important goal pursued by metrological inspection institutions at all levels.

[0003] There are two ways to regularly detect the pressure gauge: verification and calibration. The main way is to send it to a metrological inspection institution for inspection (send for inspection), and the proportion of on-site inspection is very small. Sending for inspection means that the user unit (or: the sending unit) sends someone (the sender) to send the pressure gauge to be inspected to a qualified metrological verification (calibration) institution, and then completes the acceptance at the front desk, issues a "commission form", and then sends it to the laboratory for inspection by an inspector. Finally, the metrological inspection institution issues a verification (calibration) certificate and generates the original record. When the sender sends the pressure gauge to the metrological inspection institution for inspection reporting and the latter accepts it at the front desk, the front desk staff first needs to count the number of pressure gauges to be inspected; the basic information such as the factory serial number, manufacturer name, accuracy grade, and range on each pressure gauge needs to be copied and checked (either at the front desk or during inspection), because these basic information must be recorded in the verification (calibration) certificate and inspection original record of each pressure gauge. After sending for inspection and acceptance, currently, the pressure gauges are placed in the packaging of the sender for loading the gauges. These packages include plastic boxes, plastic bags, and various other bags, which are very chaotic. When conducting inspections in the laboratory, since only pressure gauges of the same type (with the same range and accuracy grade) can be inspected simultaneously for multiple pieces, the inspector needs to re-organize and classify the pressure gauges randomly placed in various packages. At present, these auxiliary tasks such as inputting (checking) the basic information such as the factory serial number, manufacturer name, accuracy grade, and range of the pressure gauge and sorting and classifying the pressure gauges during inspection take up more than half of the time and energy of the inspector. At the same time, the front desk staff also needs to complete a series of tasks such as quantity counting, information input (checking), and generation and printing of the commission form during acceptance. In addition, in some economically developed regions, there are many senders and a large inspection volume, and often need to queue up and wait.

[0004] Therefore, there is an urgent need to upgrade the reporting and information collection processes for pressure gauge verification (acceptance) with intelligent technology, so as to significantly improve the work efficiency and quality of metrology and testing institutions. Summary of the Invention

[0005] To address this, the present invention provides a self-service reporting and information collection method and system for pressure gauge metrological verification. Based on machine vision technology, the reporting of pressure gauges is completed by the submitter himself / herself. This method not only saves the metrological testing agency manpower in the acceptance process, but also automatically collects basic information such as the factory number, manufacturer name, accuracy class and range of each submitted pressure gauge. At the same time, it can also simultaneously complete the quantity count and neatly stack the submitted pressure gauges into a unified turnover box, which significantly improves work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a self-service reporting and information collection method for pressure gauge metrological verification, comprising: Receive inspection declaration instructions initiated by the submitter and receive inspection declaration business type information; Place the pointer-type pressure gauge to be tested face down on the glass plate; The photoelectric sensor located below the glass plate is used to detect the position status of the pointer pressure gauge under test, and a trigger signal is sent to the host computer after the position is detected. After receiving the trigger signal, the host computer controls the industrial camera to take a picture of the pointer pressure gauge under test and saves the obtained image to a preset storage location. The image is analyzed to obtain the recognition result, and the recognition result is transmitted to the host computer and saved; wherein, the recognition result includes the factory number, manufacturer name, accuracy class, range and outer diameter information of the pointer pressure gauge under test; After the photo is taken, the host computer outputs voice and text prompts to guide the person submitting the sample to confirm the image. When the image is normal, the host computer prompts the person submitting the sample to place the pointer pressure gauge face up into the turnover box. Repeat the above steps of placement, inspection, photographing, identification and boxing until all pointer pressure gauges to be inspected have been reported for inspection. After the submitter confirms the inspection application, the human-machine interface pops up a signature page, receives the submitter's signature information, and controls the printer to print the order form.

[0007] In one embodiment of the present invention, receiving inspection declaration service type information includes: The human-computer interaction interface provides two business options: mandatory verification and entrusted verification. When mandatory inspection is selected, the mandatory inspection number is received by the person submitting the inspection or by scanning a code. When choosing to entrust an inspection application, the system receives the information of the entrusting unit entered by the person submitting the application, or imports the entrustment information from online appointment information or electronic spreadsheet files.

[0008] In one embodiment of the present invention, the photoelectric sensor detects whether a pointer-type pressure gauge is placed on the glass plate by means of beam reflection, and the detection signal is converted and uploaded to the host computer through a USB interface.

[0009] In one embodiment of the present invention, controlling an industrial camera to take a picture of the pointer-type pressure gauge under test and saving the obtained image to a preset storage location includes: Name the image and save it to the local hard drive or a specified path on the server.

[0010] In one embodiment of the present invention, transmitting the recognition result to the host computer and saving it includes: Save the identified serial number, manufacturer name, accuracy class, range, and outer diameter information to a specified file or database table.

[0011] In one embodiment of the present invention, the host computer outputs voice prompts and text prompts to guide the person submitting the image for verification, including: The system uses voice prompts and on-screen text prompts to guide the person submitting the sample to check whether the collected images are complete. When an image is incomplete, misplaced, or duplicated, the system receives a deletion command from the submitter, deletes the abnormal image, and prompts the submitter to remove the currently inspected pointer pressure gauge and reposition it for re-image capture.

[0012] In one embodiment of the present invention, after all the pointer pressure gauges to be inspected have completed the inspection, the pointer pressure gauges in the turnover box are all neatly stored with their surfaces facing upwards, so that they can be sorted and tested according to their outer diameter, range, and accuracy class in the future.

[0013] In one embodiment of the present invention, it further includes: The identified serial number, manufacturer name, accuracy class, range, and outer diameter information are imported into the business system to generate original verification or calibration records and certificates.

[0014] In one embodiment of the present invention, it further includes: During the inspection process, video footage of the inspection process is captured by surveillance cameras and displayed simultaneously at the front desk; Voice communication between the person submitting the sample and the front desk staff can be achieved through a microphone to provide remote guidance during the sample submission process.

[0015] This invention also provides a self-service reporting and information collection system for pressure gauge metrological verification, comprising: The system includes a self-service inspection cabinet, a host computer installed inside the self-service inspection cabinet, a human-machine interface installed on the top of the self-service inspection cabinet, a tabletop installed on the self-service inspection cabinet, a glass plate installed on the tabletop, an industrial camera installed below the glass plate, photoelectric sensors installed below the glass plate and spaced apart from the industrial camera, a microphone, a monitoring camera, a signature input device, a printer, a turnover box, and an identification module, a storage module, and a business system interface module electrically connected to the host computer, all installed on the self-service inspection cabinet. The human-computer interaction interface is used to receive the inspection declaration instruction initiated by the person submitting the inspection, receive the inspection declaration business type information, and pop up a signature page and receive signature information after the inspection is completed. The glass plate is located in the middle of the table surface and is used to support the pointer pressure gauge to be tested, so that the person submitting the test gauge can place it with the surface facing down on it. The photoelectric sensor is used to detect whether the pointer-type pressure gauge to be tested is placed on the glass plate, and sends a trigger signal to the host computer after it is detected that the gauge is in place. The industrial camera is used to take pictures of the pointer pressure gauge to be tested placed on the glass plate after the host computer issues a control command according to the trigger signal. The host computer saves the obtained image to a preset storage location. The identification module is connected to the host computer and is used to analyze the images captured by the industrial camera to obtain identification results including the factory number, manufacturer name, accuracy class, range and outer diameter information. The storage module is connected to the host computer and is used to store the images captured by the industrial camera and the recognition results; The host computer is used to control the human-computer interaction interface to output text prompts and control the voice output unit to output voice prompts after the photo is taken, guiding the person submitting the sample to confirm the image; when the image is normal, the person submitting the sample is prompted to place the pointer pressure gauge to be inspected face up into the turnover box. The turnover box is used to place the pointer pressure gauges that have completed the inspection, so that all the pointer pressure gauges to be inspected can be stored in an orderly manner with the surface facing up after the inspection is completed, which is convenient for subsequent sorting and testing according to outer diameter, range and accuracy class. The business system interface module is connected to the host computer and is used to import the identification results into the business system to generate original verification or calibration records and certificates. The surveillance camera is installed on the upper part of the self-service inspection and declaration cabinet and faces the inspection and declaration operation area. It is used to capture video of the inspection and declaration process and display it synchronously on the front desk. The microphone is installed on the self-service inspection station cabinet to enable voice communication between the person submitting the inspection and the front desk staff, so as to provide remote guidance during the inspection process; The signature input device and the printer are respectively connected to the host computer. The signature input device is used to input signature information after the submitter confirms the completion of the inspection application. The printer is used to print the consignment form according to the control of the host computer.

[0016] The technical solution of the present invention has the following advantages compared with the prior art: The self-service reporting and information collection method and system for pressure gauge metrological verification described in this invention allows the acquisition of pressure gauge serial numbers, manufacturer names, pressure gauge ranges, accuracy classes, and outer diameters, which can be imported into the business system for generating original records and issuing certificates, significantly improving work efficiency. Furthermore, intelligent pressure gauge testing equipment using machine vision can simplify operation steps by importing this information. Simultaneously, this method also ensures that submitted gauges are neatly stacked in a turnover box, greatly facilitating subsequent verification (calibration) work.

[0017] This invention enables the acceptance of metrological verification (calibration) of pressure gauges to be completed without the need for verification agency personnel, and the submitter does not need to wait in line. At the same time, detailed information of each pressure gauge is obtained efficiently, which significantly improves work efficiency. Attached Figure Description

Those skilled in the art can reasonably determine the specific meaning of the above terms in this invention based on the specific content of the technical solution.

[0028] Example 1 Reference Figure 1 , Figure 2 As shown, this embodiment provides a self-service reporting and information collection method for pressure gauge metrological verification. The self-service reporting station is equipped with a host computer 2 (computer host), a photoelectric sensor 8 and an industrial camera 7 inside, and a monitoring camera and a microphone 3 outside. The front is a human-machine interface 4 (touch display). The table surface 9 of the self-service reporting station is a highly transparent glass plate 6 in the center, which is located directly above the photoelectric sensor 8 and the industrial camera 7. Its side length exceeds the dial diameter of the largest pressure gauge.

[0029] The method includes: S1. Receive the inspection order initiated by the person submitting the inspection and receive the inspection business type information.

[0030] Among them, the human-computer interaction interface 4 provides two business options: mandatory verification and entrusted inspection. When mandatory inspection is selected, the mandatory inspection number is received by the person submitting the inspection or by scanning a code. When choosing to entrust an inspection application, the system receives the information of the entrusting unit entered by the person submitting the application, or imports the entrustment information from online appointment information or electronic spreadsheet files.

[0031] S2. Place the pointer-type pressure gauge 11 to be tested face down on the glass plate 6.

[0032] S3. The photoelectric sensor 8 located below the glass plate 6 is used to detect the position status of the pointer pressure gauge 11 to be tested, and a trigger signal is sent to the host computer 2 after the position is detected.

[0033] The photoelectric sensor 8 detects whether a pointer-type pressure gauge is placed on the glass plate 6 by means of beam reflection, and transmits the detection signal to the host computer 2 through the USB interface after conversion.

[0034] S4. After receiving the trigger signal, the host computer 2 controls the industrial camera 7 to take a picture of the pointer pressure gauge 11 to be inspected, and saves the obtained image to a preset storage location. Specifically, the image is named and saved to a specified path on the local hard drive or server.

[0035] S5. Analyze the image and obtain the recognition result, transmit the recognition result to the host computer 2 and save it; wherein, the recognition result includes the factory number, manufacturer name, accuracy class, range and outer diameter information of the pointer pressure gauge 11 to be tested; save the factory number, manufacturer name, accuracy class, range and outer diameter information obtained by recognition to a specified file or database table.

[0036] In addition, the identified serial number, manufacturer name, accuracy class, range and outer diameter information are imported into the business system to generate original verification or calibration records and certificates.

[0037] S6. After the photo is taken, the host computer 2 outputs voice prompts and text prompts to guide the submitter to confirm the image. The voice prompts and on-screen text prompts the submitter to check whether the acquired image is complete. If the image is incomplete, misplaced, or duplicated, the computer receives a deletion command from the submitter to delete the abnormal image and prompts the submitter to take out the currently inspected pointer pressure gauge 11 and reposition it for re-photographing.

[0038] When the image is normal, the person submitting the test instrument is prompted to place it face up into the turnover box 10. After all the pointer pressure gauges 11 to be tested have been submitted for inspection, the pointer pressure gauges in the turnover box 10 are all neatly stored face up for subsequent sorting and testing according to outer diameter, range, and accuracy class.

[0039] S7. Repeat the above steps of placement, inspection, photographing, identification and box placement (S2-S6) until all pointer pressure gauges 11 to be inspected have been reported for inspection.

[0040] During the inspection process, surveillance camera 5 captures video of the inspection process and displays it simultaneously to the front desk; Microphone 3 enables voice communication between the person submitting the sample and the front desk staff to provide remote guidance during the sample submission process.

[0041] S8. After the submitter confirms the inspection application, the human-machine interface 4 will pop up a signature page to receive the submitter's signature information and control the printer to print the consignment form.

[0042] Example 2 Reference Figures 2 to 4 As shown in the figure, this embodiment provides a self-service reporting and information collection system for pressure gauge metrological verification, including: The system includes: a self-service inspection cabinet 1; a host computer 2 installed inside the self-service inspection cabinet 1; a human-computer interaction interface 4 installed on the upper part of the self-service inspection cabinet 1; a tabletop 9 installed on the self-service inspection cabinet 1; a glass plate 6 installed on the tabletop 9; an industrial camera 7 installed below the glass plate 6; photoelectric sensors 8 installed below the glass plate 6 and spaced apart from the industrial camera 7; a microphone 3, a monitoring camera 5, a signature input device, a printer, a turnover box 10, and an identification module, a storage module, and a business system interface module electrically connected to the host computer 2, respectively. The human-computer interaction interface 4 is used to receive the inspection declaration instruction initiated by the person submitting the inspection, receive the inspection declaration business type information, and pop up a signature page and receive signature information after the inspection is completed. The glass plate 6 is located in the middle of the table surface 9 and is used to support the pointer pressure gauge 11 to be tested, so that the person submitting the test can place the pointer pressure gauge 11 to be tested with its surface facing down on it. The photoelectric sensor 8 is used to detect whether the pointer pressure gauge 11 to be tested is placed on the glass plate 6, and sends a trigger signal to the host computer 2 after detecting that it is in place. The industrial camera 7 is used to take pictures of the pointer pressure gauge 11 to be tested placed on the glass plate 6 after the host computer 2 issues a control command according to the trigger signal. The host computer 2 saves the obtained image to a preset storage location. The identification module is connected to the host computer 2 and is used to analyze the images acquired by the industrial camera 7 to obtain identification results including the factory number, manufacturer name, accuracy class, range and outer diameter information. The storage module is connected to the host computer 2 and is used to store the images captured by the industrial camera 7 and the recognition results; The host computer 2 is used to control the human-computer interaction interface 4 to output text prompts and control the voice output unit to output voice prompts after the photo is taken, so as to guide the person submitting the image to confirm the image; when the image is normal, the person submitting the image is prompted to place the pointer pressure gauge 11 to be inspected into the turnover box 10 with the surface facing up. The turnover box 10 is used to place the pointer pressure gauges that have completed the inspection, so that all the pointer pressure gauges 11 to be inspected can be stored in an orderly manner with their surfaces facing up after the inspection is completed, which is convenient for subsequent sorting and testing according to outer diameter, range and accuracy class. The business system interface module is connected to the host computer 2 and is used to import the identification results into the business system to generate original verification or calibration records and certificates. The surveillance camera 5 is installed on the upper part of the self-service inspection station cabinet 1 and faces the inspection operation area. It is used to capture video of the inspection process and display it synchronously on the front desk. The microphone 3 is installed on the self-service inspection station cabinet 1 to enable voice communication between the person submitting the inspection and the front desk staff, so as to provide remote guidance during the inspection process; The signature input device and the printer are respectively connected to the host computer 2. The signature input device is used to input signature information after the submitter confirms the inspection application is completed, and the printer is used to print the consignment form according to the control of the host computer 2.

[0043] In practice, after the person submitting the inspection report clicks the "Start Inspection" button on the touchscreen, the host computer program 2 starts and displays two options on the screen: "Mandatory Inspection" and "Entrustment." The "Machine Vision Image Reading Program" also starts simultaneously. If "Mandatory Inspection" is selected, a "Mandatory Inspection Number" input box will pop up. After entering (or scanning) the mandatory inspection number, the "Mandatory Inspection" information will be imported. If "Entrustment" is selected, an input box will pop up for entering the information of the entrusting unit. Information from "Online Appointment Information" or an Excel file can also be imported from external sources.

[0044] Then, the person submitting the pressure gauge places it face down on the glass plate 6 of the platform 9, following the prompts (text and voice). An industrial camera 7 and a photoelectric sensor 8 are installed below the center area of ​​the glass plate 6. The latter, after its sensitivity (detection distance) is adjusted, can detect the presence of a pressure gauge on the glass plate 6 through the reflection of a light beam. After the pressure gauge is placed on the glass plate 6, the latter outputs an electrical signal, which is converted and uploaded to the host computer 2 program via the computer's USB port. Upon receiving the signal, the host computer 2 program activates the industrial camera 7 to take a picture, names the photo, and saves it to a "specified location" (a specified path on the local hard drive or server). After the "machine vision image reading program" scans and finds a new photo at the "specified location," it analyzes the photo, identifies the pressure gauge's serial number, manufacturer name, accuracy class, range, and outer diameter (mm), and saves this information to a specified file or database table. The host computer 2 program then displays and saves this information to the database. After taking the photo, a prompt (voice or on-screen text) will appear to check if the photo is complete. If the photo is abnormal (incomplete, misplaced, or duplicate), it can be deleted, the gauge removed, and re-taken. If everything is normal, place the pressure gauge face up in the adjacent storage box 10. Follow the same steps for other submitted gauges. Once all pressure gauges are in storage box 10, click the "End Operation" button on the screen. A "Signature" page will pop up. The submitter signs and clicks "OK," and the "Request Form" will begin printing (a message will appear saying "Request Form Printing"). After printing, the submitter retrieves the request form as instructed, concluding the inspection. Simultaneously, all pressure gauges after inspection are neatly stored face up in the uniformly sized storage box 10, allowing inspectors to quickly retrieve pressure gauges of the same specifications (outer diameter, range, accuracy) for testing.

[0045] During the inspection and testing procedure, the monitoring camera will record the entire process and display it simultaneously at the front desk of the metrology and testing institution. The person submitting the inspection and the front desk staff of the metrology and testing institution can communicate through microphone 3. If the person submitting the inspection encounters any difficult problems, they can get guidance through microphone 3.

[0046] The above method can significantly improve the cumbersome manual operation of the existing pressure gauge inspection and acceptance process. In the existing process, the person submitting the inspection usually needs to fill out an acceptance form, the front desk staff counts the number of pressure gauges, the inspector or the front desk staff writes down the factory number and manufacturer name of each pressure gauge, and the inspector sorts and selects the pressure gauges that are piled up messily in the packaging. The whole process is labor-intensive, inefficient and prone to errors.

[0047] By adopting the above method (or system), firstly, the quantity counting and basic information collection of pressure gauges submitted for inspection can be completed efficiently without the need for on-site participation of front-line staff and inspectors. The pressure gauges can also be neatly and orderly stored in the turnover box 10, thereby improving the automation level and operational efficiency of the inspection acceptance process. Secondly, when issuing verification certificates, calibration certificates, and original records, the system has pre-acquired and saved basic information such as the factory serial number, manufacturer name, accuracy class, and range, thus further improving the efficiency of certificate and record generation and effectively reducing errors caused by manual data entry. Furthermore, for intelligent pressure gauge testing equipment with machine vision reading capabilities, the steps of pre-entering parameters such as the accuracy class, range, and outer diameter of the pressure gauge under inspection can be reduced. Existing visual reading systems typically require pre-entry of this data before identification and testing; therefore, this method (or system) can further improve overall testing efficiency.

Therefore, the present invention can take the form of a completely hardware embodiment, a completely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present invention can take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.
