Description

Technical Field

[0001] The present invention relates to the technical field of electronic scales, and in particular to an electronic scale and an anti-cheating method thereof. Background Art

[0002] like Figure 1 As shown, the existing electronic scale includes a weighing sensor 310, an amplifier 320, an A / D converter 330, a processor 340 and a display panel 350 connected in sequence. When weighing, an object is placed on the scale pan of the electronic scale, and the weighing sensor 310 can detect the object on the scale pan and convert the gravity into an analog signal, which is amplified by the amplifier 320 and converted into a digital signal by the A / D converter 330, which is processed by the processor 340 and finally displayed on the display panel 350.

[0003] In the current market environment, cheating with electronic scales occurs from time to time, which harms the interests of consumers. Unscrupulous merchants cheat by disassembling and modifying electronic scales, or by using magnets to absorb the stainless steel scale plate of the electronic scale during the weighing process, thereby achieving the purpose of cheating.

[0004] In order to prevent unscrupulous merchants from disassembling and modifying electronic scales to achieve cheating, for example, in the patent with Chinese patent publication number CN212807275U, entitled "Anti-cheating electronic scale", a trigger mechanism device and a scale body are provided, the scale body is provided in a hollow cavity, the trigger mechanism device is provided inside the scale body, the trigger mechanism device includes an upper contact, a lower contact, a connecting rod, a support rod and a mounting base plate, the mounting base plate is provided on the inner bottom wall of the scale body, the support rod is vertically connected to the mounting base plate, one end of the connecting rod is hinged on the support rod, and the trigger switch device is used to determine whether the bottom of the electronic scale body is opened, the abnormal use of the electronic scale can be captured, and the circuit board inside the scale body can be locked, and an alarm can be issued at the same time, thereby achieving anti-cheating. The disadvantage is that it can only prevent cheating by disassembly and modification, and cannot prevent cheating by adsorbing the scale pan with a magnet. Summary of the invention

[0005] In view of the problem that the anti-cheating electronic scale in the prior art can only prevent cheating through disassembly and modification, but cannot prevent cheating through magnet adsorption of the scale pan, the present invention provides an electronic scale and an anti-cheating method thereof, which have the functions of preventing cheating by disassembly and preventing cheating by magnetic attraction.

[0006] In order to achieve the above technical purpose, the present invention provides a technical solution, which is an electronic scale, comprising a main body and a scale pan, wherein the scale pan is a ferromagnetic part, and the electronic scale further comprises a magnetic sensor, a magnetic part, a shielding part, a display panel and a processor; the main body comprises a detachably connected base and a cover, wherein a receiving cavity is formed between the base and the cover, and the processor and the magnetic sensor are located in the receiving cavity; The magnetic sensor is electrically connected to a processor, and the processor is used to control the display of the display panel according to the sensing signal of the magnetic sensor; The shielding member comprises a first shielding member and a second shielding member abutting against each other, the first shielding member is connected to the base, the second shielding member is connected to the cover body, a magnetic field shielding cavity is enclosed between the first shielding member and the second shielding member, and the magnetic member is located in the magnetic shielding cavity.

[0007] In the present technical solution, when the electronic scale is in use, when a magnet approaches the electronic scale, the magnetic sensor can sense the magnet, and the processor can control the display of the display panel according to the sensing signal of the magnetic sensor, thereby preventing cheating by adsorbing the scale pan with the magnet. In addition, when unscrupulous merchants want to cheat by disassembling and modifying the electronic scale, they need to disassemble the base and cover of the electronic scale. During the disassembly process, the first shielding member and the second shielding member will also be separated. At this time, the magnetic field shielding cavity cannot shield the magnetic field of the magnetic member, and the magnetic sensor will detect the magnetic field of the magnetic member. Therefore, the processor can prevent the display panel from reading normally, thereby preventing cheating by disassembling and modifying the electronic scale.

[0008] The present invention is further configured such that: the first shielding member and the second shielding member abut against each other along a first direction; When the base and the cover are in an assembled state, the direction in which the base and the cover are relatively close to or away from each other is the reference direction; The first direction is parallel to a reference direction; or, the first direction is perpendicular to the reference direction.

[0009] In the present technical solution, when the base and the cover are in an assembled state, the first shielding member and the second shielding member abut against each other along the first direction, and together enclose a completely closed magnetic field shielding cavity. This design effectively isolates the magnetic field generated by the magnetic member, preventing it from interfering with the external magnetic sensor, thereby ensuring the accuracy of the weighing result of the electronic scale; however, when the base and the cover are disassembled, since the first shielding member is connected to the base and the second shielding member is connected to the cover, they will separate, resulting in the magnetic field shielding cavity no longer being completely closed. At this time, the magnetic field generated by the magnetic member will no longer be effectively shielded, and the magnetic sensor will be able to detect the magnetic field of the magnetic member.

[0010] The present invention is further configured such that: the shielding component is located in the accommodating cavity; and / or the magnetic sensor component is arranged close to the shielding component.

[0011] In the present technical solution, the shielding member is located in the accommodating cavity, so that the shielding member is effectively protected and is not easily damaged or disturbed by the external environment. Since the shielding member is a key component for protecting the magnetic member from interference from the external magnetic field, its stability and integrity are crucial to the accurate weighing of the electronic scale. Therefore, placing the shielding member in the accommodating cavity can ensure its normal shielding effect on the magnetic member, thereby maintaining the weighing accuracy of the electronic scale; the magnetic sensor member is arranged close to the shielding member, which helps the magnetic sensor member to more accurately detect the magnetic field changes of the magnetic member. When the magnetic sensor member is close to the shielding member, it can more directly receive the magnetic field signal generated by the magnetic member, reducing the attenuation and interference during the signal transmission process, thereby improving the sensitivity and accuracy of the detection, so that the electronic scale can respond to the slight changes in the magnetic field of the magnetic member more quickly, which helps to timely discover and prevent potential cheating behaviors; the shielding member is located in the accommodating cavity, and the magnetic sensor member is arranged close to the shielding member, so that the internal layout of the electronic scale is more reasonable, which helps to reduce the volume and weight of the electronic scale. At the same time, it is also convenient for the assembly and maintenance of the electronic scale, and improves production efficiency and maintenance convenience.

[0012] The present invention is further configured as follows: a plurality of magnetic sensors are provided, the plurality of magnetic sensors are arranged in a ring-shaped manner, and the surrounding surfaces of the plurality of magnetic sensors are parallel to the supporting surface of the scale pan for placing the objects to be weighed.

[0013] In the present technical solution, multiple magnetic sensors are arranged in a circular pattern, so that the magnetic sensors can cover a wider area, thereby more comprehensively detecting the changes in the magnetic field around the electronic scale, monitoring the magnetic field from multiple angles and directions, reducing the detection blind area, and improving the sensitivity and response speed to external magnetic field interference. When the surrounding surfaces of the multiple magnetic sensors are parallel to the supporting surface of the scale pan for placing the objects to be weighed, the magnetic field changes from above or around the scale pan can be more directly captured, further improving the sensitivity of detection; since the magnetic sensors can more accurately detect changes in the external magnetic field, the electronic scale can more effectively prevent cheating through external magnetic field interference. The magnetic sensors arranged in a circular pattern can verify and complement each other. When a magnetic sensor detects an abnormal magnetic field, other magnetic sensors can provide additional data support, thereby more accurately determining whether cheating occurs.

[0014] The present invention is further configured as follows: the magnetic sensing element is a magnetic sensor; And / or, the magnetic member is a magnet; And / or, the shielding component is a stainless steel component.

[0015] In this technical solution, the magnetic sensor is selected as the magnetic sensor, which can ensure high-precision detection of magnetic field changes. The magnetic sensor has the characteristics of high sensitivity and fast response speed, and can accurately capture the slight changes in the magnetic field around the electronic scale, which helps the electronic scale to more accurately determine whether there is external magnetic field interference, so as to take preventive measures in time to ensure the accuracy of the weighing result; the magnet, as a magnetic part, can provide a stable and strong magnetic field, ensuring that the electronic scale is not affected by external magnetic field interference under normal working conditions, and the magnetic field characteristics of the magnet enable the electronic scale to work more stably, reducing the weighing error caused by magnetic field fluctuations. At the same time, the selection of the magnet is also convenient for cooperation with the magnetic sensor to achieve more accurate magnetic field detection and anti-cheating functions; the stainless steel part is used as a shielding part, which has good magnetic shielding performance and can effectively isolate the interference of the external magnetic field on the internal components of the electronic scale. The corrosion resistance and stability of stainless steel also ensure that the shielding part is not easily damaged or failed during long-term use, thereby ensuring the long-term stability and reliability of the electronic scale.

[0016] The present invention is further configured as follows: the signal sending component is electrically connected to the processor, and the signal sending component is used to send a signal to a remote background.

[0017] In the present technical solution, the signal sending component equipped with the electronic scale is electrically connected to the processor, and can transmit the status information of the electronic scale to the remote background in real time, so that the supervisor can understand the working status of the electronic scale in real time through the remote background without having to visit the site, thereby greatly improving the monitoring efficiency; when the magnetic sensor detects that the magnetic field strength of the magnet is greater than the set value, it indicates that there is external magnetic field interference or cheating. At this time, the signal sending component can quickly send a signal to the remote background to notify the supervisor that the electronic scale is in an abnormal state.

[0018] The present invention is further configured such that: the signal receiving component is electrically connected to the processor, and the signal sending component is used to receive a signal sent by a remote background.

[0019] In the present technical solution, the signal receiving element equipped with the electronic scale is electrically connected to the processor, and can receive signals sent by the remote background, so that the electronic scale has the ability of remote communication and can receive instructions from the supervisor or management system; the processor can control the display of the display panel according to the signal received by the signal receiving element; through the cooperation of the signal receiving element and the processor, the supervisor can remotely control the working status of the electronic scale without having to go to the site to operate it.

[0020] The present invention is further configured as follows: the electronic scale further comprises an alarm component, the alarm component is located in the accommodating cavity; the alarm component is electrically connected to the processor.

[0021] In the present technical solution, the alarm component equipped with the electronic scale is located in the accommodating cavity and is electrically connected to the processor. It can quickly sound an alarm when an abnormal situation is detected, so that when cheating, magnetic field interference or other abnormal conditions occur, the electronic scale can immediately warn the surrounding people through the alarm component to remind them to pay attention; the connection between the alarm component and the processor enables the electronic scale to respond to cheating more intelligently. When the magnetic sensor detects an abnormal magnetic field or the signal receiving component receives an alarm command from the remote background, the processor can immediately trigger the alarm component and sound a loud alarm, effectively deterring cheaters.

[0022] Another technical solution provided by the present invention is a method for preventing cheating of an electronic scale, comprising the following steps: S100, using a magnetic sensor to detect the magnetic field strength around the electronic scale, and transmitting the detection result to a processor; S200, using the processor to process the detection result and controlling the display of the display panel according to the detection result; S300, when the magnetic field strength in the detection result is greater than a set value, controlling the processor to lock the display panel and make the display panel display abnormal.

[0023] In the present technical solution, the magnetic field strength around the electronic scale is detected in real time by a magnetic sensor to ensure that any abnormal magnetic field interference can be discovered in time, which helps to quickly identify potential cheating behaviors, such as using external magnets to interfere with weighing results; the processor receives the detection results of the magnetic sensor and performs intelligent processing. According to the processing results, the processor can control the display content of the display panel to ensure the accuracy and fairness of the weighing results. Under normal circumstances, the display panel will accurately display the weighing results; when an abnormal magnetic field is detected, the display panel will display abnormal information to alert the user; when the magnetic field strength in the detection result is greater than the set value, the processor will automatically lock the display panel to prevent cheaters from covering up cheating behaviors by tampering with the display results. At the same time, the display panel will display abnormal information, such as "magnetic field interference" or "weighing abnormality", to clearly inform the user that the current weighing result may be inaccurate.

[0024] The present invention is further configured such that: when the lock time of the display panel exceeds a set value, the processor releases the lock on the display panel and restores the normal display of the display panel.

[0025] In the technical solution, the lock time of the display panel is set. When the lock time exceeds the set value, the processor automatically releases the lock on the display panel, effectively preventing the display panel from being locked for a long time due to misoperation, system failure or external interference, and ensuring the normal use of the electronic scale. After the lock time exceeds the set value, the display panel will resume its normal display function, and the user can continue to use the electronic scale for weighing operations without worrying about not being able to obtain the weighing results due to locking.

[0026] The beneficial effects of the present invention are as follows: (1) It has the functions of preventing disassembly cheating and magnetic attraction cheating; (2) When the electronic scale is in use, when a magnet approaches the electronic scale, the magnetic sensor can sense the magnet, and the processor can control the display of the display panel according to the sensing signal of the magnetic sensor, thereby preventing cheating by adsorbing the scale pan with the magnet. In addition, when unscrupulous merchants want to cheat by disassembling and modifying the electronic scale, they need to disassemble the base and cover of the electronic scale. During the disassembly process, the first shielding part and the second shielding part will also be separated. At this time, the magnetic field shielding cavity cannot shield the magnetic field of the magnetic part, and the magnetic sensor will detect the magnetic field of the magnetic part. Therefore, the processor can prevent the display panel from reading normally, thereby preventing cheating by disassembling and modifying the electronic scale. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figures 2 to 5 As shown, as the first embodiment of the present invention, an electronic scale includes a main body 100 and a scale pan 200, wherein the scale pan 200 is a ferromagnetic member 500, and the electronic scale further includes a magnetic sensor 400, a magnetic member 500, a shielding member 600, a display panel 350, and a processor 340; The main body 100 includes a detachably connected base 110 and a cover 120, a receiving cavity 130 is formed between the base 110 and the cover 120, and the processor 340 and the magnetic sensor 400 are located in the receiving cavity 130; The magnetic sensor 400 is electrically connected to the processor 340, and the processor 340 is used to control the display of the display panel 350 according to the sensing signal of the magnetic sensor 400; The shielding member 600 includes a first shielding member 610 and a second shielding member 620 that are abutted against each other. The first shielding member 610 is connected to the base 110, and the second shielding member 620 is connected to the cover body 120. A magnetic field shielding cavity 630 is enclosed between the first shielding member 610 and the second shielding member 620, and the magnetic member 500 is located in the magnetic shielding cavity.

[0031] In this embodiment, when the electronic scale is in use, when a magnet approaches the electronic scale, the magnetic sensor 400 can sense the magnet, and the processor 340 can control the display of the display panel 350 according to the sensing signal of the magnetic sensor 400, thereby preventing cheating by adsorbing the scale pan 200 with a magnet. In addition, when unscrupulous merchants want to cheat by disassembling and modifying the electronic scale, they need to disassemble the base 110 and the cover 120 of the electronic scale. During the disassembly process, the first shielding member 610 and the second shielding member 620 will also be separated. At this time, the magnetic field shielding cavity 630 cannot shield the magnetic field of the magnetic member 500, and the magnetic sensor 400 will detect the magnetic field of the magnetic member 500. Therefore, the processor 340 can prevent the display panel 350 from reading normally, thereby preventing cheating by disassembling and modifying the electronic scale.

[0032] Preferably, the first shielding member 610 and the second shielding member 620 are shells, and the two shells are arranged to form a closed magnetic field shielding cavity 630 .

[0035] In the present technical solution, when the base 110 and the cover 120 are in the assembled state, the first shielding member 610 and the second shielding member 620 are in contact with each other along the first direction, and together form a completely closed magnetic field shielding chamber 630. This design effectively isolates the magnetic field generated by the magnetic member 500, preventing it from interfering with the external magnetic sensor 400, thereby ensuring the accuracy of the weighing result of the electronic scale; however, if Figure 4 As shown, when the base 110 and the cover 120 are disassembled, since the first shielding member 610 is connected to the base 110 and the second shielding member 620 is connected to the cover 120, they will be separated, resulting in that the magnetic field shielding cavity 630 is no longer completely closed. At this time, the magnetic field generated by the magnetic member 500 will no longer be effectively shielded, and the magnetic sensor 400 can detect the magnetic field of the magnetic member 500. Figure 3 As shown, the first direction is parallel to the reference direction; Figure 5 As shown, the first direction is perpendicular to the reference direction.

[0036] like Figure 3 As shown, the shielding member 600 is located in the accommodating cavity 130; and / or, the magnetic sensor 400 is arranged close to the shielding member 600. The shielding member 600 is located in the accommodating cavity 130, so that the shielding member 600 is effectively protected and is not easily damaged or disturbed by the external environment. Since the shielding member 600 is a key component for protecting the magnetic member 500 from external magnetic field interference, its stability and integrity are crucial to the accurate weighing of the electronic scale. Therefore, placing the shielding member 600 in the accommodating cavity 130 can ensure its normal shielding effect on the magnetic member 500, thereby maintaining the weighing accuracy of the electronic scale; the magnetic sensor 400 is arranged close to the shielding member 600, which helps the magnetic sensor 400 to more accurately detect the magnetic field changes of the magnetic member 500. When the magnetic sensor 4 When the electronic scale is close to the shielding member 600, it can more directly receive the magnetic field signal generated by the magnetic member 500, reducing the attenuation and interference in the signal transmission process, thereby improving the sensitivity and accuracy of the detection, and enabling the electronic scale to respond more quickly to slight changes in the magnetic field of the magnetic member 500, which helps to timely discover and prevent potential cheating behaviors; the shielding member 600 is located in the accommodating cavity 130, and the magnetic sensor 400 is arranged close to the shielding member 600, so that the internal layout of the electronic scale is more reasonable, which helps to reduce the volume and weight of the electronic scale, and at the same time, it is also convenient for the assembly and maintenance of the electronic scale, and improves production efficiency and maintenance convenience.

The alarm component 900 equipped with the electronic scale is located in the accommodating cavity 130 and is electrically connected to the processor 340. It can quickly issue an alarm when an abnormal situation is detected, so that when cheating, magnetic field interference or other abnormal conditions occur, the electronic scale can immediately issue an alarm to the surrounding people through the alarm component 900 to remind them to pay attention; the connection between the alarm component 900 and the processor 340 enables the electronic scale to deal with cheating more intelligently. When the magnetic sensor 400 detects an abnormal magnetic field or the signal receiving component 800 receives an alarm instruction from the remote background, the processor 340 can immediately trigger the alarm component 900 and issue a loud alarm sound to effectively deter cheaters.

[0044] Preferably, the alarm element 900 is a buzzer.

[0045] like Figure 6As shown, as a second embodiment of the present invention, an anti-cheating method for an electronic scale includes the following steps: S100, using a magnetic sensor 400 to detect the magnetic field strength around the electronic scale, and transmitting the detection result to a processor 340; S200, using the processor 340 to process the detection result, and controlling the display of the display panel 350 according to the detection result; S300, when the magnetic field strength in the detection result is greater than a set value, controlling the processor 340 to lock the display panel 350 and causing the display panel 350 to display abnormally.

[0046] In this embodiment, the magnetic field strength around the electronic scale is detected in real time by the magnetic sensor 400 to ensure that any abnormal magnetic field interference can be discovered in time, which helps to quickly identify potential cheating behaviors, such as using external magnets to interfere with weighing results; the processor 340 receives the detection result of the magnetic sensor 400 and performs intelligent processing.
