Description

Technical Field

[0001] The present invention relates to the technical field of anti-cheating detection for electronic weighing devices, and specifically to a portable metering monitoring device and testing method for electronic price scales. Background Art

[0002] As an important tool in commercial transactions, the weighing accuracy of electronic price scales is directly related to transaction fairness. In recent years, the application of portable detection devices in the field of market supervision has gradually increased. In the prior art, portable detection devices usually include components such as standard weights and video recorders for on-site calibration and recording of the weighing process. In addition, some devices also integrate intelligent functions such as real-time data transmission and automatic analysis to improve detection efficiency.

[0003] However, the prior art has the following deficiencies:

[0004] Firstly, the functions are single. Existing devices usually can only achieve a single function, such as calibration or recording, and cannot meet the requirements of cheating identification and weighing accuracy monitoring simultaneously.

[0005] Secondly, the portability is poor. Some devices are large in size and complex in operation, which are not suitable for on-site rapid monitoring.

[0006] Finally, the data integration is insufficient. The data recording and analysis functions of existing devices are relatively scattered, lacking a unified data management platform, resulting in low traceability and credibility of monitoring results.

[0007] In view of the deficiencies of the prior art, we propose a portable metering monitoring device and testing method for electronic price scales to solve the above problems. Summary of the Invention

[0008] Aiming at the problems of single function, insufficient intelligence, poor portability and low data credibility of existing electronic price scale detection devices, the present invention provides a portable on-site metering monitoring device, aiming to solve the following technical problems: realizing the integration of weighing calibration, cheating identification, video recording and detection report; through the real-time analysis of dynamic weighing data and video images, with the help of the cheating feature codes updated in real time by the system network database, identifying hidden cheating behaviors and balancing detection accuracy and portability in lightweight design; the technical difficulties in solving the above problems include: the compact layout and lightweight design of multi-functional components, the rapid identification of cheating features based on multi-modal data fusion, and the synchronous encrypted storage of detection data and video evidence.

[0009] To achieve the above objectives, the present invention is realized through the following technical solutions: A portable metering monitoring device for an electronic price scale, comprising:

[0039] By providing an electronic weighing scale portable metering monitoring device and a testing method in the embodiments of the present application, the problems of single function, poor portability, and insufficient data integration of existing portable monitoring devices are solved.

[0040] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0041] An embodiment of the present invention discloses a portable metering monitoring device and a testing method for an electronic weighing scale.

[0042] Embodiment 1: A portable metering monitoring device for an electronic weighing scale

[0043] According to the attached Figures 1-5 As shown, it includes a box body 1 and a box cover 2. The box body 1 and the box cover 2 are rotatably connected, and the closed box body 1 and box cover 2 can be lifted and carried by hand. The box body 1 has a modular bin design, so that components such as weights 5 and cameras 3 can be independently fixed in a group of modular bins, so that the components do not interfere with each other, and are earthquake-resistant and drop-proof. In addition, components such as the three-axis telescopic rod 31, the weight 5, the camera 3, and the control panel 4 can all be independently disassembled and replaced, which is convenient for maintenance and upgrade. In terms of anti-interference, combined with the copper plating layer of the circuit board + the metal shell, the shielding strength is relatively high, and the dynamic weighing data is denoised based on Kalman filtering. Inside the box body 1, there is a weight 5. The weight of one weight 5 is 1 kilogram, and there are a total of 5 weights 5 (other specifications of weights can be replaced according to actual needs). The weights 5 are made of stainless steel material, and are precision processed and surface treated to ensure accuracy and durability. The weights 5 are used to weigh and detect electronic scales in places such as vegetable markets.

[0044] Referring to the attached Figures 1-3, inside the box body 1, there is a camera 3 for anti-cheating monitoring. The camera 3 is equipped with a 1080P high-definition camera, supports infrared night vision function, and can clearly record the weighing process in low-light environments. It also has a three-axis telescopic rod 31 and a hydraulic telescopic rod 32. One end of the three-axis telescopic rod 31 is connected to the camera 3. The three-axis telescopic rod 31 is made of carbon fiber composite material and manufactured by the compression molding process to ensure light weight and high strength. It can be quickly extended to a height of 2 meters, suitable for detection in complex environments. It integrates an infrared ranging sensor to automatically identify the height of the electronic scale platform and adjust the telescopic length. The bottom end of the three-axis telescopic rod 31 is movably hinged to the inner wall of the box body 1. There are two groups of hydraulic telescopic rods 32 hinged on the inner wall of the box body 1, and the other ends of the two groups of hydraulic telescopic rods 32 are movably hinged to the outer wall of the three-axis telescopic rod 31. The three-axis telescopic rod 31 and the hydraulic telescopic rod 32 are used to quickly lift and lower the camera 3 in a dual-control manner, that is, the placement angle of the three-axis telescopic rod 31 can be adjusted manually or electrically, thereby driving the camera 3 to quickly lift and lower, so that the camera 3 automatically focuses on the electronic scale. The drive power source 6 is fixedly arranged inside the box body 1, such as a battery, etc. The drive power source 6 is used to provide power for the operation of the camera 3. One side of the box body 1 is provided with a power cord interface 61 connected to the drive power source 6. The built-in lithium battery supports PD fast charging and can work continuously for 8 hours. An external solar charging interface, that is, the power cord interface 61, is provided, and the solar charging interface supports outdoor emergency charging. The inside of the box body 1 and the box cover 2 are provided with solar panel wiring 62. The top surface of the box body 1 is provided with a placement cavity 33 for placing the camera 3. The placement cavity 33 is electrically connected to the drive power source 6 through the solar panel wiring 62. When the camera 3 is placed flat inside the placement cavity 33, it can be automatically charged.

[0045] Refer to the appendix Figure 1 , the control panel 4 is fixedly arranged inside the box cover 2, and there is a network-connected cheating feature database in the box cover 2 that is connected to the camera 3. The control panel 4 can cooperate with the camera 3 online to upload the monitoring situation to the cloud at the scene. Select information such as the electronic scale level and graduation value to be monitored on the control panel 4, and then the control panel 4 automatically displays the corresponding errors of different weights 5 on the interface to provide a reference basis for detection.

[0046] Refer to the appendix Figure 4 , there is a remote positioning terminal 7 inside the box body 1. The remote positioning terminal 7 is used to automatically remotely locate the box body 1 and the monitoring position of the camera inside the box body 1. The remote positioning terminal 7 is electrically connected to the drive power source 6 through the solar panel wiring 62. When law enforcement officers conduct anti-cheating detection on an electronic scale at a certain place, when there is cheating on the electronic scale, the remote positioning terminal 7 can automatically locate and record the location of the place to provide point information for subsequent registration.

[0047] Embodiment 2: A testing method for a portable measurement monitoring device for an electronic price computing scale

[0048] See attached Figures 1-5 ,

[0049] In the first step, the law enforcement officer carries the camera 3 to the scene through the closed box 1 and the box cover 2. After the scene is in place, the box cover 2 is opened, the power is pressed to turn on the control panel 4, and then the "real-time monitoring" displayed on the control panel 4 is clicked. Then, the "camera focus" displayed on the control panel 4 is clicked, and the camera 3 is lifted to a suitable position through the infrared ranging sensor of the camera 3, that is, the three-axis telescopic rod 31 is manually lifted to lift the camera 3 to a suitable position, or the power is pressed, and the power controls the hydraulic telescopic rod 32 to operate, so that the hydraulic telescopic rod 32 automatically lifts the camera 3 to a suitable position;

[0050] In the second step, after the camera 3 is in place, according to the prompt on the control panel 4, that is, the loading quantity automatically generated on the control panel 4, the law enforcement personnel manually load the weights 5 on the electronic scale to be tested in sequence according to the steps, and the camera 3 automatically and synchronously records the weighing process, and recognizes the real-time weight value of the pricing scale through image recognition. In this case, if the indication is out of tolerance, it means that the weighing data of the electronic scale is unqualified. The law enforcement personnel transfer the electronic scale to the relevant verification agency. At this time, the result is pushed to the law enforcement terminal via Bluetooth or Wi-Fi, and the PDF report can be generated with one click, and the monitoring is completed; on the contrary, when the weighing result of the electronic scale is qualified, the control panel 4 continues to be connected to the camera 3 via Bluetooth, and the data is automatically added to the storage location specified by the control panel 4. After the loading is completed, the control panel 4 automatically generates the monitoring results, and at the same time, the camera 3 performs real-time AI-assisted screen analysis, for example, the AI ​​algorithm analyzes the fluctuation of weighing data (such as sudden zeroing and jump changes) in real time, and the video screen synchronously detects abnormal actions (such as holding a remote control, blocking the camera) to identify cheating behavior;

[0051] In the third step, if there are no abnormal conditions based on the first two steps, the law enforcement officer loads a specified number of standard weights 5 on the electronic scale, and the law enforcement officer stands on the side of the electronic scale, where the camera 3 should not be blocked, and then presses the keyboard keys manually in sequence according to the prompts on the control panel 4, such as a single keyboard key or a cheating password combination provided by the online cheating feature database, to identify the cheating behavior. When the camera 3 detects the presence of cheating features in the password recognition process, it will directly indicate that the electronic scale is unqualified; otherwise, when the password recognition process is normal, continue to open the electronic scale housing according to the prompts on the control panel 4, and then use the camera 3 to identify the internal circuit board of the electronic scale, and then intelligently identify and compare whether there is a suspicious remote control cheating device installed on the internal circuit board of the electronic scale according to the network data image library;

[0052] Step 4: When the internal circuit board of the electronic scale is recognized by the camera 3 as having remote control cheating features, it indicates that the electronic scale is unqualified. At this time, the result is pushed to the law enforcement terminal via Bluetooth or Wi-Fi, supporting one-key generation of a PDF report, and the monitoring is completed. On the contrary, when the internal circuit board of the electronic scale is not recognized by the camera 3 as having remote control cheating features, it indicates that the electronic scale is normal. At this time, the result is continuously pushed to the law enforcement terminal via Bluetooth or Wi-Fi, supporting one-key generation of a PDF report, and the monitoring is completed.

[0053] Step 5: After the monitoring is completed, the three-axis telescopic rod 31 is retracted manually or electrically, so that the three-axis telescopic rod 31 and the camera 3 connected to the three-axis telescopic rod 31 are retracted into the interior of the box body 1 until the three-axis telescopic rod 31 and the camera 3 are reset to the state as shown in the appendix Figure 1 . At this time, the camera 3 is placed flat inside the placement cavity 33, so that the driving power supply 6 automatically charges the camera 3. Then, press the power button again to turn off the control panel 4 and each module connected to the control panel 4 via the network. Finally, close the box cover 2 so that the box body 1 in the closed state can be carried by hand.

[0054] Embodiment 3: Law enforcement in the vegetable market

[0055] Scenario: Law enforcement officers suspect that the electronic scale of a certain stall is cheating.

[0056] Operation process:

[0057] The law enforcement officers expand the three-axis telescopic rod 31 manually or electrically, etc., so that the camera 3 installed at one end of the three-axis telescopic rod 31 is in place. Then, the law enforcement officers place the 5 kg weight 5 on the weighing pan of the electronic scale and press the button on the control panel 4 to monitor the cheating feature code. When the button "3 + tare" is pressed, the weighing data of the electronic scale suddenly returns to zero. At this time, with the weight unchanged, the weight indication value of the pricing scale is changed by pressing the button, which is the cheating feature. Subsequently, the system automatically generates a report by pressing the button, and the video and the report are automatically transmitted to the law enforcement cloud, and the evidence chain is complete.

[0058] Embodiment 4: Law enforcement in the vegetable market

[0059] Scenario: Law enforcement officers suspect that the electronic scale of a certain stall is cheating.

[0060] Operation process:

[0061] The law enforcement officers deploy the three-axis telescopic rod 31 manually or electrically, etc., so that the camera 3 installed at one end of the three-axis telescopic rod 31 is in place. Then, the law enforcement officers place the 5 kg weight 5 on the weighing pan of the electronic scale. After completing steps such as monitoring the cheating feature code as prompted on the control panel 4, open the outer shell of the electronic price scale, adjust the angle so that the camera of the camera 3 can capture the key components inside the price scale, and combine with the network picture database to identify and compare the key components of the main circuit board of the price scale, and determine that the price scale is installed with a suspicious remote control cheating device, which is the cheating feature. Through the key, the system automatically generates a report, and the video and report are automatically transmitted to the law enforcement cloud, and the evidence chain is complete.
