Description

Technical Field

[0001] This utility model relates to the field of belt scale technology, and in particular to a continuous cumulative automatic weighing instrument detection device for online monitoring of physical objects. Background Technology

[0002] The metrological verification of continuous cumulative automatic weighing instruments (i.e., belt scales) must strictly follow JJG 195-2019 "Verification Procedure for Continuous Cumulative Automatic Weighing Instruments (Belt Scales)". In the material testing phase, it is necessary to continuously weigh tens or even hundreds of tons of material, currently relying mainly on manual operation for metrological verification. This process is not only complex but also extremely time-consuming, causing significant inconvenience for both metrology personnel performing the verification on-site and users responsible for daily maintenance within the company.

[0003] During belt conveyor transport, a large amount of dust and noise are generated on-site, and the equipment itself also poses significant safety hazards. Currently, the calibration requirements for belt scales rely on on-site personnel visually observing and transcribing the scale's instrument data. However, this method not only significantly increases the probability of human error but also poses a considerable threat to the personal safety of workers.

[0004] Meanwhile, electronic belt scales are highly susceptible to environmental interference. After prolonged operation, factors such as belt tension changes and mechanical component fatigue can cause zero-point drift during the cumulative weighing process, negatively impacting the accuracy of the final measurement results. Since visual observation alone cannot fully trace the entire measurement process, it is difficult to effectively verify any doubts about the accuracy of the measurement results.

[0031] Please see Figures 1 to 3 This utility model provides a continuous cumulative automatic weighing instrument detection device 100 for online monitoring of physical objects. The continuous cumulative automatic weighing instrument 200 includes an instrument data display terminal 201 and a belt conveyor terminal 202. The detection device includes a first industrial camera 1, a second industrial camera 2, a laser sensor 3 and a terminal data processing module 4.

[0032] The first industrial camera 1, the second industrial camera 2, and the laser sensor 3 are all connected to the terminal data processing module 4; the terminal data processing module 4 is equipped with an OCR algorithm and a target tracking algorithm; the edge feature algorithm is to perform calculations on edge nodes close to the data source or device to achieve fast data processing and reduce dependence on the cloud or central server.

[0033] The first industrial camera 1 is positioned on one side close to the instrument data display terminal 201 and is used to acquire data from the belt scale instrument data display terminal 201; the OCR algorithm is used to process the data acquired by the first industrial camera 1 from the instrument data display terminal 201.

[0034] The second industrial camera 2 and laser sensor 3 are positioned near the belt conveyor end 202 to detect the presence of material at the belt conveyor end 202. A target tracking algorithm is used to process the data acquired by the second industrial camera 2 and laser sensor 3.

[0035] The second industrial camera 2 and the laser sensor 3 perform a dual determination of whether there is material at the belt conveyor end 202.

[0036] When material is being conveyed at the belt conveyor end 202 and when the belt conveyor end 202 is idling (i.e., there is no material on the belt conveyor end 202), there is a height difference. The laser sensor 3 can sense the height change and feed it back to the terminal data processing module 4. The terminal data processing module 4 controls the second industrial camera 2 to take pictures of the belt conveyor end 202. The terminal data processing module 4 processes the data collected by the second industrial camera 2 to determine whether there is material at the belt conveyor end 202.

[0037] If there is no material on the belt conveyor end 202, but the displayed value on the instrument data display end 201 is still increasing or decreasing, then the continuous cumulative automatic weighing instrument 200 exhibits a value drift phenomenon. Therefore, the zero-point drift phenomenon of the continuous cumulative automatic weighing instrument 200 can be monitored by the first industrial camera 1, the second industrial camera 2, and the laser sensor 3.

[0038] Specifically, the terminal data processing module 4 includes a vision control and data processing module 41 and a serial port module 42;

[0039] The first industrial camera 1, the second industrial camera 2, and the laser sensor 3 are all connected to the serial port module 42, which is connected to the vision control and data processing module 41.

[0040] Specifically, the terminal data processing module 4 also includes a power supply module 43, which supplies power to the first industrial camera 1, the second industrial camera 2, the laser sensor 3, the vision control and data processing module 41, and the serial port module 42.

[0041] Specifically, the terminal data processing module 4 further includes a communication transmission cloud module 44, and the vision control and data processing module 41 is connected to the communication transmission cloud module 44. The detection device also includes a computer terminal 5, and the communication transmission cloud module 44 is communicatively connected to the computer terminal 5. Data collected by the first industrial camera 1, the second industrial camera 2, and the laser sensor 3 are transmitted to the computer terminal 5 via the communication transmission cloud module 44 and stored on the computer terminal 5. Inspection personnel can view the data collected by the first industrial camera 1, the second industrial camera 2, and the laser sensor 3 through the computer terminal 5. Therefore, when the accuracy of the measurement results is questioned, effective verification and backtracking can be performed, improving data reliability. Furthermore, inspection personnel can edit control commands on the computer terminal 5. These control commands are transmitted to the vision control and data processing module 41 via the communication transmission cloud module 44, and then the vision control and data processing module 41 controls the first industrial camera 1, the second industrial camera 2, and the laser sensor 3.

[0042] Specifically, it also includes a gimbal bracket 6, one end of which extends to the instrument data display terminal 201 and is connected to the first industrial camera 1;

[0043] The other end of the gimbal bracket 6 extends to the belt conveyor end 202 and is connected to the second industrial camera 2 and the laser sensor 3.

[0044] Specifically, it also includes two tripods 7, one of which is set at the instrument data display terminal 201 and connected to the first industrial camera 1;

[0045] Another tripod 7 is set at the belt conveyor end 202 and connected to the second industrial camera 2 and the laser sensor 3.

[0046] The advantages of this invention are as follows: This invention communicates with the terminal data processing module 4 via two industrial cameras and a laser sensor 3, enabling the detection device to have remote detection capabilities. This effectively reduces the safety risks faced by personnel operating on-site and ensures the personal safety of staff. This invention can monitor the operating status of the continuous cumulative automatic weighing instrument 200 in real time, accurately capturing abnormal readings. When abnormal situations such as zero-point drift occur, such as when the laser sensor 3 and the second industrial camera 2 jointly detect that there is no material on the belt conveyor end 202 but the reading on the instrument data display end 201 still changes, a warning message can be issued in a timely manner, facilitating timely fault handling and ensuring the accuracy of measurement results. This invention can perform comprehensive and quantitative evaluation and analysis of measurement data, completely recording the entire measurement process. Compared with traditional methods of visual observation and manual data transcription, it can effectively avoid human error. Furthermore, when the accuracy of the measurement results is questioned, effective verification and backtracking can be performed, improving data reliability. It changes the cumbersome process of traditional manual operation, improving detection efficiency and reducing the inconvenience caused by manual operation through automated monitoring and data processing. It provides strong support for manufacturing enterprises in key aspects such as material procurement, use and production. Through accurate measurement and effective monitoring, it helps enterprises control the production process from the source, reduce cost waste caused by inaccurate measurement, and effectively achieve the goal of cost reduction and efficiency improvement.
