Description

Technical Field

[0001] The present application relates to the technical field of measuring equipment detection, and more specifically, to a detection device for preventing electronic scales from being cracked or cheated. Background Art

[0002] An electronic scale is an electronic weighing device that integrates modern sensor technology, electronic technology, and computer technology. Electronic scales have more functions than traditional scales. In addition to weighing, they can also automatically calculate prices based on the weighed items. Therefore, many businesses now use electronic scales to cheat, and their cheating behavior is specifically reflected in the setting of unit prices for items.

[0003] As for this type of cheating behavior, the existing method for detecting cheating on electronic scales usually uses the software in the host of the computer system to give the electronic scale different input instructions, that is, to simulate the key instructions of the electronic scale. After the instructions are input to the electronic scale, the display screen of the electronic scale is photographed to collect the data displayed on the display screen of the electronic scale. The displayed data is then analyzed to determine whether the electronic scale has been cheated.

[0004] Existing electronic scale cheating detection systems typically only test one scale at a time, resulting in slow detection efficiency. Furthermore, with the widespread adoption of intelligent systems, existing electronic scale displays are now available not only with self-luminous digital panels but also with liquid crystal displays (LCDs) that display more information. Existing detection equipment lacks lighting, so it cannot capture or clearly capture data from display panels with low or insufficient luminescence. This limits the ability of existing electronic scale cheating detection systems to detect electronic scales.

[0005] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0043] like Figure 1 、 Figure 2 、 Figure 3As shown, this embodiment provides a detection device for preventing electronic scales from being cheated or cracked, which mainly includes: a cabinet 100, multiple imagers 200, and at least one light-emitting component 300. The cabinet 100 can be a vertical cabinet 100. For the convenience of structural description, the structure is described as follows: the cabinet 100 is arranged in the vertical direction, with the direction of the cabinet 100 facing the operator being the front. A test chamber 130 is provided within the cabinet 100. The test chamber 130 can be located at the upper portion of the cabinet 100. The test chamber 130 is provided with a closable chamber door 131. The electronic scale 10 to be tested is placed into the test chamber 130 by opening the chamber door 131. During the test, the chamber door 131 is closed to prevent the electronic scale 10 in the test chamber 130 from being disturbed. The test chamber 130 of this embodiment has a large space and can accommodate multiple electronic scales 10 to be tested. Multiple electronic scales 10 to be tested can be arranged side by side in the left-right direction. Multiple imagers 200 are disposed within the test chamber 130 and are each corresponding to a plurality of electronic scales 10. In this embodiment, the imagers 200 can be industrial cameras, achieving relatively good image recognition and judgment performance. Existing electronic scales 10 mostly use digital tube displays, which inherently display data by emitting light. Therefore, display data can be captured by directly photographing the imager 200. However, with the continuous advancement of liquid crystal display technology (LCD panels are relatively low in cost), current electronic scales 10 are becoming increasingly intelligent. Some electronic scales 10 using LCD screens have low or insufficient screen luminescence (e.g., TFT displays without backlight). This results in poor display performance in the relatively dark test chamber 130, resulting in poor imager 200 acquisition of the display data of the electronic scale 10. Therefore, a light-emitting assembly 300 is further disposed within the test chamber 130. The light-emitting assembly 300 provides illumination to supplement the display of the electronic scale 10 with poor or no backlight, thereby enabling the imager 200 to capture a more tilted screen display image. In addition, a host 111 is also provided in the cabinet 100. The host 111 is electrically connected to the imager 200. The data displayed on the display screen of the corresponding electronic scale 10 is collected by multiple imagers 200 respectively, and then the detection system in the host 111 automatically performs detection, thereby realizing intelligent detection of cheating behavior of the electronic scale 10, standardizing and normalizing the weighing of the electronic scale 10, and thus protecting the rights and interests of consumers.

[0044] like Figure 1 、 Figure 2 、 Figure 3As shown, the electronic scale anti-cheating and cracking detection device of this embodiment can accommodate multiple electronic scales 10 to be tested by disposing multiple imagers 200 within the test chamber 130 of the cabinet 100. Since the multiple imagers 200 are disposed in a one-to-one correspondence with the multiple electronic scales 10, the multiple imagers 200 can respectively capture the data displayed on the display screens of the corresponding electronic scales 10 for cheating detection. Simultaneously, cheating detection is implemented for multiple electronic scales 10 within the cabinet 100, and the data captured by the multiple imagers 200 is synchronously processed by a host 111, greatly improving detection efficiency. Furthermore, at least one light-emitting component 300 is disposed within the test chamber 130. The light-emitting component 300 is disposed within the test chamber 130 and is used to provide illumination. For electronic scales 10 with low or insufficient screen illumination, the light-emitting component 300 can provide illumination within the test chamber 130, achieving fill light, thereby enabling the imager 200 to capture the data displayed on the screen of the electronic scale 10. For conventional self-luminous electronic scales 10, the light-emitting component 300 does not need to be turned on. For electronic scales 10 with LCD screens with dim backlights, the light can be turned on via the host or control buttons. This allows the device to detect cheating on almost all electronic scales 10 with display panels, improving the practicality of the anti-cheating detection device for electronic scales.

[0045] like Figure 3 、 Figure 4 As shown, further, each imager 200 of this embodiment is connected to the cabinet 100 via a first adjustment bracket 210. The position and shooting angle of the imager 200 are adjusted via the corresponding first adjustment bracket 210. The angle and direction of the imager 200 can be adjusted via the first adjustment bracket 210. Therefore, when photographing electronic scales 10 of different specifications, the lens of the imager 200 can be directed toward the display screen of the electronic scale 10, thereby improving the imaging quality and more stably capturing the on-screen data of the electronic scale 10.

[0046] like Figure 3 、 Figure 4As shown, the first adjustment bracket 210 of this embodiment specifically includes a first base 211 and a double-rod extension bracket 212. The first base 211 is mounted on the inner wall of the test chamber 130, the double-rod extension bracket 212 is connected to the first base 211, and the imager 200 is connected to the double-rod extension bracket 212. Specifically, the double-rod extension bracket 212 is a commonly used bracket for instruments, such as the Mitutoyo double-rod magnetic meter base bracket. This standard product is commercially available, has low procurement costs, and a simple structure. This reduces the production cost of the device while achieving the function of adjusting the position and angle of the imager 200. The first base 211 can be a fixed base, fixed to the inner wall above the front side of the test chamber 130 (above the chamber door 131) via screws, or it can be fixed to the top inner wall of the test chamber 130. This can meet the screen capture requirements of most electronic scales 10. The first base 211 of this embodiment also utilizes a magnetic base, a standard component available on the market. It can be attached to different locations within the test chamber 130, allowing the imager 200 to be positioned appropriately for the specific structure of the electronic scale 10. This facilitates testing electronic scales 10 with displays that are high or far from the scale body, requiring adjustment of the imager 200's position to accommodate these non-standard structures. In this case, the magnetic base can be removed and moved, allowing it to be fixed to the bottom surface of the test chamber 130 or even the scale body itself, further facilitating the capture of displayed data on the electronic scale 10 and enabling testing.

[0047] like Figure 3 、 Figure 4 As shown, this embodiment further includes multiple light-emitting assemblies 300 corresponding to the multiple imagers 200. Specifically, two imagers 200 can be provided, allowing two electronic scales 10 to be placed in the test chamber 130 for simultaneous testing. Correspondingly, two light-emitting assemblies 300 can also be provided, allowing the light-emitting assemblies 300 to illuminate the screens of the corresponding electronic scales 10, providing fill light and improving imaging quality.

[0048] like Figure 3 、 Figure 4As shown, the lighting assembly 300 of this embodiment specifically includes a second adjustment bracket 310 and an illuminating lamp 320. The second adjustment bracket 310 is connected to the inner wall of the test chamber 130, and the illuminating lamp 320 is connected to the second adjustment bracket 310. The position and luminous angle of the illuminating lamp 320 can be adjusted by the second adjustment bracket 310. In the specific structure, the illuminating lamp 320 is fixed to the upper side of the front inner wall of the test chamber 130 (above the chamber door 131) via the second adjustment bracket 310, and can be fixed side by side with the imager 200. Placing both the imager 200 and the illuminating lamp 320 above the chamber door 131 can reduce interference with the electronic scale 10 entering through the chamber door 131. The angle and direction of the illuminating lamp 320 can be adjusted via the second adjustment bracket 310, so that the illumination light can be adjusted as needed when photographing electronic scales 10 of different specifications.

[0049] like Figure 3 、 Figure 4 As shown, the second adjustment bracket 310 of this embodiment specifically includes a second base 311 and a universal meter bracket 312. The second base 311 is mounted on the inner wall of the test chamber 130, the universal meter bracket 312 is mounted on the second base 311, and the lighting lamp 320 is connected to the universal meter bracket 312. The second base 311 can also be a magnetic base, and the universal meter bracket 312 is also a common bracket and is easy to purchase. Its operation is similar to that of the first adjustment bracket 210. For details, please refer to the operating principles and effects of the first adjustment bracket 210.

[0050] It is easy to imagine that the first adjustment bracket 210 and the second adjustment bracket 310 of this embodiment can also adopt other commonly used brackets, which can achieve angle and position adjustment to solve the technical problem.

[0051] like Figure 3 、 Figure 4 As shown, further, a socket 133 is provided in the test chamber 130 of this embodiment, and the socket 133 is used to power the electronic scale 10. When some old electronic scales 10 are low on battery or have no power, the socket 133 can be used to power these electronic scales 10 to be tested, so that these electronic scales 10 can also be tested normally. The socket 133 of this embodiment is set on the bottom surface of the test chamber 130, and a cover is provided on the socket 133 that can be flipped over. The cover protects the socket 133 to prevent dust or accumulated water on the electronic scale 10 from falling into the socket 133 and damaging the socket 133 during the process of moving the electronic scale 10.

[0052] like Figure 1 、 Figure 2As shown, further, the chamber door 131 of this embodiment is a double-door, and a magnetic door stop 132 is provided on the bottom surface of the test chamber 130. The magnetic door stop 132 is located in the middle of the left and right directions of the test chamber 130. The magnetic door stop 132 attracts the double-door to close the test chamber 130. Since multiple electronic scales 10 are to be tested in the test chamber 130, the left and right distance of the test chamber 130 is relatively long. The double-door is used to open the test chamber 130 in the left and right directions respectively, making it more convenient to open and close the test chamber 130. The magnetic door stop 132 cooperates with the double-door, so that the double-door is fixed by suction when closing, and can also be easily pulled open when the closing function is realized, which is convenient for the operator.

[0053] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, the cabinet 100 of this embodiment also includes: a bottom bin 110 and an operating table 120, the operating table 120 is located above the bottom bin 110, and the test bin 130 is located above the operating table 120. The host 111 can be set in the bottom bin 110, and the host 111 is electrically connected to the imager 200 through a cable running in the cabinet 100. The light-emitting component 300 can be electrically connected to the host, or it can be controlled separately by a button. When the light-emitting component 300 is electrically connected to the host, it can be uniformly controlled by the host, thereby improving the intelligence level of this device. A display 121 and a command input device 122 are provided on the operating table 120, and the display 121 and the command input device are electrically connected to the host respectively. The detection process of the host's detection system will be displayed on the display 121. The command input device 122 can be a mouse and a keyboard, which can operate the host's detection system, thereby enabling intelligent detection of cheating behavior of the electronic scale 10.

[0054] like Figure 3 、 Figure 5 As shown, further, in this embodiment, a plurality of test positions 134 (predetermined areas within the test chamber) are provided within the test chamber 130. A positioning member 140 is correspondingly provided on each test position 134. The positioning member 140 is used to position and place the electronic scale 10, so that the multiple electronic scales 10 are placed on the corresponding test position 134. Since multiple electronic scales 10 can be placed simultaneously within the test chamber 130, the positioning member 140 is required to distinguish between the various test positions. When placing the electronic scales 10 to be tested, the operator can place each electronic scale 10 relatively accurately on the corresponding test position based on the identification and positioning of the positioning member 140. In this way, the area captured by the imager 200 roughly corresponds to the display area of ​​the electronic scale 10, which speeds up the placement process of the electronic scale 10 and improves the testing efficiency.

[0055] like Figure 3 、 Figure 5As shown, further, the positioning member 140 of this embodiment can adopt various forms to achieve position identification and positioning to achieve technical effects.

[0056] like Figure 3 、 Figure 5 As shown, for example, the positioning member 140 of this embodiment includes: an L-shaped baffle 141, which is used to abut against and limit the adjacent outer wall of the electronic scale 10; a plurality of different sets of screw holes are provided on the bottom surface of the test chamber 130, and the L-shaped baffle 141 is connected to different screw holes by screws 143, so that the L-shaped baffle 141 is located at different positions on the bottom surface of the test chamber 130. In the specific structure, the L-shaped baffle 141 has waist-shaped holes 142 on both sides perpendicular to each other. Therefore, by inserting screws 143 through the waist-shaped holes 142, the L-shaped baffle 141 can be fixed to different positions on the bottom plate of the test chamber 130, thereby marking and limiting different test positions. After positioning once, electronic scales 10 of the same specifications can all be positioned by the L-shaped baffle 141 at that position, thereby improving the placement accuracy of the electronic scale 10.

[0057] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
