Description

Technical Field

[0001] The present invention relates to the technical field of electronic scales, and in particular to a non-invasive electronic scale monitoring device and a working method thereof. Background Art

[0002] As a commonly used measuring tool in commercial activities, the accuracy and fairness of electronic scales directly affect consumer rights and market order. However, some unscrupulous businesses use various means to tamper with electronic scales in order to seek improper benefits. This cheating behavior seriously damages the market trading environment, infringes on consumer interests, and weakens the credibility of market supervision departments.

[0003] At present, cheating methods are hidden and difficult for ordinary consumers to detect. Once a problem occurs, the lack of effective evidence makes it difficult to hold people accountable. Although electronic scales have quality inspections and annual inspections, the existing anti-dismantling measures lack alarm and recording functions, and if they are modified, they are difficult to identify; the main cheating methods of electronic scales are "key cheating" and "remote control cheating", and the existing supervision methods usually rely on regular manual inspections or calibrations, which is not only time-consuming and labor-intensive, but also prone to multiple cheating during the inspection intervals.

[0004] Existing anti-cheating methods are often relatively simple and have low reliability, such as Chinese patents CN102564554B and CN103994810B; Figure 1 As shown, some of them judge cheating by monitoring the weight change from the sensor to the display end through the main program, but once the main program is destroyed, it loses its effectiveness, such as Chinese patent CN117516688B; others judge the risk of cheating by collecting key data and issue a notification when the threshold is exceeded, such as Chinese patent CN117782290B. However, this method relies on image recognition, the software and hardware are complex and costly, and it lacks anti-disassembly and anti-counterfeiting technology, and its reliability is limited. In addition, even if cheating can be identified, if the regulatory authorities cannot restore the operation process, there is still a lack of effective evidence.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be further understood that the term "and / or" used in the present description and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0051] The accuracy of electronic scales is affected by tampering by unscrupulous merchants, especially in seafood markets, which has damaged consumer rights and market order. Existing anti-cheating methods are diverse but unreliable, and lack effective alarm and recording functions, making it difficult to hold people accountable. Current supervision relies on manual inspections and cannot prevent cheating in real time, leading to challenges in market supervision.

[0052] To this end, an embodiment of the present invention provides a non-invasive electronic scale monitoring device, such as Figure 3As shown, the Internet of Things technology is used to monitor the operation and data of the electronic scale in real time to ensure data integrity and security. Through anti-tampering design and wireless communication, regulatory authorities can access and analyze the status of the electronic scale at any time to detect abnormal conditions in a timely manner. The device in the figure is a non-intrusive design, and normal work such as data collection will not affect the data transmission between the electronic scale main control chip and the display and case. 1, 2, and 3 in the figure are anti-tampering nodes.

[0053] Specifically, the non-intrusive electronic scale monitoring device monitors the weight and user operation of the electronic scale in real time through the data collection, anti-tampering detection and data processing module 30. The device has data storage and encryption functions, and can be connected to the management platform through the communication module 50 to facilitate data retrieval and analysis. In addition, the device also includes a warning module 80 and a recovery module to respond to disassembly behavior and playback historical data.

[0054] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] See also Figure 2 , Figure 2 A schematic block diagram of a non-invasive electronic scale monitoring device provided by an embodiment of the present invention, the non-invasive electronic scale monitoring device comprises: a data acquisition module 10, an anti-tampering detection module 20, a data processing module 30, a data storage module 40 and a communication module 50; the data acquisition module 10 is connected to the electronic scale, and the data acquisition module 10 is connected to the anti-tampering detection module 20;

[0056] The data acquisition module 10 is used to obtain the weight, unit price and total amount data measured by the electronic scale and the matrix keyboard operation data of the user on the electronic scale;

[0057] The anti-tamper detection module 20 is used to monitor the data transmission status of the digital tube display tube, matrix keyboard, power supply and main control chip of the electronic scale to record the disassembly behavior;

[0058] The data processing module 30 is used to receive the data from the data acquisition module 10 and the anti-tampering detection module 20 and integrate them into a data packet;

[0059] A data storage module 40, for storing data packets according to timestamps;

[0060] The communication module 50 is connected to the management platform and is used for the management platform to retrieve data packets.

[0061] In this embodiment, the data acquisition module 10 is connected to an electronic scale to obtain weighing data, unit price, total amount, and user operation data (such as matrix keyboard input) in real time. Providing accurate real-time data helps to ensure the transparency and fairness of transactions. By recording user operations, subsequent analysis can be performed to prevent improper operation or malicious tampering.

[0062] The anti-tamper detection module 20 monitors the digital tube display, matrix keyboard, power supply and data transmission status of the main control chip of the electronic scale to identify and record any disassembly or tampering behavior.

[0063] Improve the safety of the equipment, detect and warn potential tampering in time, and protect the interests of consumers and merchants. This module can effectively prevent criminals from manipulating electronic scales.

[0064] The data processing module 30 receives the data from the data acquisition module 10 and the anti-tampering detection module 20 and integrates the data into a data packet.

[0065] Ensure the systematization and structuring of data, which facilitates subsequent data analysis and storage. By integrating data from different sources, you can fully understand the operating status of the electronic scale.

[0066] The data storage module 40 stores the integrated data packets according to the timestamps for later retrieval and analysis.

[0067] Provides historical data preservation for subsequent query and audit. Timestamps help track every step of the transaction process and improve data traceability.

[0068] The communication module 50 is connected to the management platform to realize the retrieval and remote monitoring of data packets.

[0069] It allows managers to monitor the operating status of electronic scales in real time and manage data centrally. It enhances management efficiency and flexibility, and can handle abnormal situations in a timely manner through remote access.

[0070] The non-intrusive electronic scale supervision device realizes comprehensive supervision of electronic scales through the coordinated work of five modules: data collection, anti-tampering detection, data processing, data storage and communication. This not only improves the security and transparency of transactions, but also helps maintain trust between merchants and customers, while providing strong data support for future market supervision.

[0071] In this embodiment, the design of the anti-tampering detection module 20 can indeed effectively monitor and record potential tampering behaviors. Specifically, its working principle includes the following aspects:

[0072] Data line signal monitoring: This module will regularly check whether the data line transmitted by the data acquisition module 10 is normal. If the expected signal is not received within the preset time, an alarm will be triggered, judging that there may be disassembly or failure. Timely detection of device disassembly or tampering helps to protect the integrity of the device and the fairness of the transaction.

[0073] External power supply detection: monitors whether the power supply module 60 is supplying power normally. If a power interruption or abnormality is detected, the event will be recorded and an alarm will be issued.

[0074] Ensure that the electronic scale operates in normal working condition to avoid data loss or operation errors caused by power supply problems.

[0075] Behavior Recording: All abnormal events and alarms will be recorded, including timestamps and specific circumstances, for subsequent auditing and analysis.

[0076] Improves the traceability of the system, making it easier for managers to investigate and take necessary measures.

[0077] Through these mechanisms, the anti-tampering detection module 20 can effectively implement security monitoring of the electronic scale and maintain the authenticity and reliability of transactions.

[0078] The functional design of the data processing module 30 is critical to ensure the data quality and reliability of the system. The following is the specific working principle and benefits of this module:

[0079] Data integration: Integrate the real-time weighing data from the data acquisition module 10, user operation information and status data from the anti-tampering detection module 20 to generate a comprehensive data package.

[0080] Stability check: Pack only stable and reliable data. For example, by setting a threshold or time interval, ensure that the data is consistent within a certain period of time before packaging.

[0081] Change detection: monitors for differences from the previous data packet and includes the new data packet only if it is significantly different from the previous data. This prevents the generation of redundant data.

[0082] By only packaging stable and reliable data, the accuracy of transmitted data is ensured and the spread of erroneous information is reduced. The generation of redundant data is limited, making data transmission more efficient and saving storage and processing resources. Timely reflection of equipment status changes provides managers with a basis for rapid response and helps them make better decisions. By recording each change in the data packet, subsequent analysis and auditing are facilitated, improving the transparency of the system.

[0083] Through the above functions and benefits, the data processing module 30 plays a vital role in the overall system and ensures the effective operation of the electronic scale monitoring device.

[0084] The communication module 50 plays an important role in the electronic scale supervision system, ensuring real-time transmission and flexible access to data. The following are the specific design and functions of the module:

[0085] Wireless data transmission: Use wireless communication technologies such as Bluetooth to transmit the integrated data packets to the host computer (such as a computer or mobile device) in real time.

[0086] Data request processing: supports the host computer's data requests for different devices, and can read data records within a specific time period according to instructions.

[0087] Multi-device support: It can establish connections with multiple electronic scale devices to ensure that the data of each device can be quickly switched and read to meet the needs of different scenarios.

[0088] Data encryption and security: During data transmission, encryption technology is used to ensure data security and prevent information from being stolen or tampered with.

[0089] Wireless transmission ensures instant data updates, allowing managers to monitor equipment status and transaction data at any time.

[0090] Supports on-demand reading of data from any time period, facilitating historical data analysis and auditing.

[0091] Users can easily access data through mobile devices or computers, improving the convenience of operation.

[0092] Wireless communication reduces wiring complexity and cost and improves overall system reliability.

[0093] Through these functions, the communication module 50 not only improves the efficiency of data transmission, but also enhances the flexibility and security of the system, providing strong support for electronic scale supervision.

[0094] In one embodiment, the data storage module 40 is used to encrypt the data packet and store the data packet according to the timestamp.

[0095] Specifically, the system can record every keyboard operation and every valid display in real time without affecting the normal operation of the scale. The recorded data will be encrypted and stored using advanced encryption technology (such as AES, RSA, etc.) to ensure the confidentiality and integrity of the data. During data transmission, security protocols are used to ensure the security of data to prevent interception or tampering during transmission. The encrypted data will be effectively stored within the set time period to facilitate subsequent data access and auditing. Checksums or hash functions are used to ensure that the data has not been tampered with during storage and transmission. Anti-tampering hardware measures (such as seals, special screws, etc.) are used to ensure that the device itself is not illegally opened or modified. Real-time monitoring of system status, recording of any abnormal operations, and timely alarms increase system security.

[0096] The design of the device combines comprehensive data logging, encrypted storage and advanced anti-tampering technology to ensure the data security and reliability of the electronic scale during use, providing strong technical support for anti-cheating.

[0097] In this embodiment, the data storage module 40 selects a hierarchical storage method to classify the electronic scale working data and working status into multiple categories for quick location and access. A relational database (such as SQLite) or a NoSQL database (such as MongoDB) can be used to store data to ensure efficient retrieval and classification of data.

[0098] Record work data content: including timestamp, operation type, user input, display content, etc.

[0099] Record working status: including the operating status of the electronic scale, fault information, maintenance records, etc.

[0100] Data is classified by time, operation type, status, and other dimensions, and users are supported to customize labels to meet specific needs. Indexes are created for commonly used query fields to improve data retrieval speed.

[0101] Encrypt sensitive data for storage to ensure data security. Automatically back up data regularly to prevent data loss. Support manual backup and restore functions.

[0102] Provides a user-friendly interface that supports quick retrieval and viewing of records at any time based on time range, operation type, etc. Supports exporting data to common formats (such as CSV, Excel) for further analysis and report making.

[0103] The device has powerful storage and classification functions, can safely and reliably record the working data and status of electronic scales, and supports users to read records at any time, providing an effective tool for the supervision and management of electronic scales.

[0104] In one embodiment, see Figure 2 The above-mentioned non-invasive electronic scale monitoring device also includes a power module 60, which is used to provide power to the data acquisition module 10, the anti-tampering detection module 20, the data processing module 30, the data storage module 40 and the communication module 50.

[0105] In one embodiment, the power module 60 includes an external power source and an internal power source.

[0106] Specifically, a high-quality external power supply is used to provide stable power to the device, ensuring that the device has sufficient energy during normal operation. Overload protection and short-circuit protection functions are designed to avoid device damage due to power problems.

[0107] The internal battery acts as a backup power source to ensure that the device can still operate normally when the external power supply is disturbed or cut off. In the event of external power failure, the internal battery can support the device to continue recording operations and detecting cheating behaviors to ensure data integrity.

[0108] Anti-interference technology is used to enhance the device's ability to resist external power interference, ensuring that the system will not shut down or fail due to unexpected interference. The system can automatically detect the power status and seamlessly switch to internal battery power when needed to ensure continuous operation.

[0109] A reliable power supply system is designed by combining external power supply and internal battery. This dual power supply solution not only provides stable power support for the device, but also ensures that the device continues to record and monitor normally when encountering external interference, thereby improving the safety and reliability of the system.

[0110] In one embodiment, see Figure 2 The above-mentioned non-invasive electronic scale monitoring device also includes a host computer recovery module 70, which is used to reproduce the display data and key operations of the electronic scale in any time period according to a specific time.

[0111] In this embodiment, the host computer recovery module 70 can reproduce the display data of the electronic scale and the user's key operation in any time period according to the set time, thereby realizing comprehensive monitoring and backtracking of the use process.

[0112] In one embodiment, see Figure 2 The above-mentioned non-invasive electronic scale monitoring device also includes a warning module 80, and the warning module 80 is used to issue a warning when the anti-tampering detection module 20 records the disassembly behavior.

[0113] In this embodiment, when the anti-tampering detection module 20 detects disassembly or other abnormal behaviors, the warning module 80 will sound an alarm to remind relevant personnel to pay attention to possible safety hazards and enhance the anti-tampering capability of the system.

[0114] Specifically, see Figures 4 to 13 , respectively presenting examples of host computer recovery and warning interfaces for different situations. Based on the recovery principle, the interface can be adjusted according to actual conditions; the supervisory host computer software, i.e., the management platform, can read the operating data of the electronic scale within a specified time period, including keyboard input and display content.

[0115] The user can select a specific time point through the interface, and the device will restore the keyboard operation and display content at that time. This function helps supervisors intuitively understand the use of electronic scales. The device records all operations and display information, providing detailed data support for regulatory authorities to help identify cheating by illegal merchants. By reproducing specific operation scenarios, regulatory authorities can obtain strong evidence, effectively combat and stop illegal activities, and maintain market order.

[0116] The device not only enhances the transparency of electronic scale operations, but also provides regulators with a powerful tool to promptly detect and deal with cheating and improve the effectiveness of market supervision.

[0117] In one embodiment, the above-mentioned data acquisition module 10 includes a display data acquisition module 10 and a key data acquisition module 10;

[0118] The display data acquisition module 10 obtains the display information of the digital tube through the I2C signal to extract the weight, unit price and total amount data;

[0119] The key data collection module 10 utilizes the scanning method of the matrix keyboard by the main control chip of the electronic scale to record the key operation of the user.

[0120] The display data acquisition module 10 is connected to the digital tube through a set signal to obtain and extract important data such as weight, unit price and total amount in real time.

[0121] In this embodiment, the set signal includes an I2C signal and other similar serial signals.

[0122] The key data collection module 10 utilizes the matrix keyboard scanning method of the electronic scale main control chip to record the user's key operations to ensure the accuracy and completeness of the operation records.

[0123] The non-intrusive electronic scale monitoring device realizes comprehensive monitoring and management of the electronic scale through the collaborative work of multiple modules. The host computer recovery module 70 and the warning module 80 improve the safety of the device, while the data acquisition module 10 ensures the real-time and accuracy of the information. This design effectively prevents cheating and ensures the fairness and transparency of the use of the electronic scale.

[0124] Specifically, the device uses the I2C protocol for data transmission and is suitable for a variety of display devices. By parsing the I2C signal, the real-time display data of the electronic scale can be effectively obtained. The matrix keyboard structure is adopted, which can efficiently detect user input. Through simple hardware connection and software scanning logic, key operations can be quickly identified. In view of the limited types of displays and keyboards, the data capture device has strong versatility. Regardless of the electronic scale of different brands or models, data collection can be achieved under a similar framework.

[0125] The device is designed so that in most cases no modification of existing hardware is required. Compatibility and expansion of data capture functions are achieved through specific software design adjustments for different electronic scales.

[0126] This device can efficiently and simply realize data capture by utilizing I2C communication and matrix key scanning principles. The versatility and flexibility of its design make it suitable for a wide range of electronic scale types, providing convenient conditions for subsequent promotion and application.

[0127] In one embodiment, the anti-tampering detection module 20 includes a digital tube removal detection module, a matrix button removal detection module and a power supply removal detection module; the digital tube removal detection module is used to perform digital tube removal detection according to the data transmission frequency of the digital tube; the matrix button removal detection module is used to perform matrix button removal detection according to the data transmission frequency of the matrix button; the power supply removal detection module is used to monitor the power supply of the electronic scale to the main control chip of the electronic scale to perform power supply removal detection.

[0128] In one embodiment, the anti-tampering detection module 20 further includes a main control chip removal detection module, which is used to perform main control chip removal detection according to the data frequency of the electronic scale main control chip.

[0129] like Figure 3 As shown in the figure, by monitoring the data transmission frequency of the digital tube, it is determined whether the digital tube is removed. If the frequency is abnormal, a warning will be triggered.

[0130] By monitoring the data transmission frequency of the matrix buttons, it detects whether the buttons have been removed. When a frequency change is detected, the system will sound an alarm.

[0131] Monitor the power supply of the electronic scale to ensure that the main control chip is powered normally. If the power supply is found to be removed or interrupted, the system will promptly alarm.

[0132] Monitor the data frequency of the main control chip to detect whether the main control chip has been removed. If the data frequency is lower than the normal range, a security warning will be triggered.

[0133] The frequency refers to whether the corresponding signal is received within the set time. Of course, it can also be the number of times the signal is received within the set time.

[0134] The anti-tamper detection module 20 ensures the integrity and safety of each key component of the electronic scale through a multi-layer monitoring mechanism, and can detect any potential disassembly or tampering behavior in real time, thereby improving the safety and reliability of the device. This design effectively prevents improper operation and ensures the fair use of the electronic scale.

[0135] Specifically, plug-in and unplug detection modules are integrated into key data lines and external power supply lines to monitor line status in real time. Physical sensors (such as Hall sensors or contact switches) are used to detect the connection status of cables to ensure that any abnormal plug-in and unplug behavior is known at any time.

[0136] Whenever an unplugging event is detected, the event information is immediately recorded in the built-in memory, including the timestamp, cable type (data cable or power cable), and event status (plugged in or unplugged). If abnormal unplugging behavior is detected multiple times in a row, the system can automatically trigger an alarm mechanism to warn you.

[0137] Post warning signs in conspicuous locations to inform users that the device has anti-tampering monitoring functions to increase psychological deterrence. Provide explanations of the legal consequences that may result from tampering to enhance the warning effect.

[0138] Ensure that the device can be connected to various types of electronic scales and design standardized interfaces for easy installation and maintenance.

[0139] Keep device firmware updated to improve its tamper resistance and data security.

[0140] All recorded data will be encrypted to ensure that it cannot be accessed by unauthorized persons.

[0141] Optional remote monitoring function transmits event logs to the cloud via the network for real-time monitoring and management.

[0142] The device effectively monitors and deters any attempt to tamper with the electronic scale or device through its plug-in and unplug detection mechanism and data logging function, providing reliable protection for the safety and data integrity of the electronic scale.

[0143] The device of this embodiment is intended to enhance the anti-cheating capability and data security of the electronic scale. Specifically, it has the following functions:

[0146] Tamper-proof design: Use tamper-proof housing and multiple detection mechanisms to monitor physical tampering and ensure that the recorded data is authentic and reliable.

[0147] Real-time monitoring and management: Wireless communication technology (such as Bluetooth) is used to upload data instantly, so that regulatory authorities can monitor the status and data of electronic scales at any time.

[0148] Review system: Develop a review function to facilitate regulators to restore historical operations and data, and help identify and deal with cheating behavior.

[0149] Standardization and interoperability: Promote industry standardization, develop unified communication protocols and data formats, and improve the interoperability of electronic scales of different brands and models.
