Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine teaching and testing technology, and in particular to a multifunctional electronic digital display balance for traditional Chinese medicine and its usage method. Background Technology

[0002] Traditional steelyard balances consist of a steelyard lever, a counterweight, a balance pan, and a steelyard rope. They rely on lever balance and visual readings, and have the following drawbacks: ① Reading the scale relies on the eye being aligned with the balance bar, resulting in significant parallax; beginners often have errors exceeding 5%. ② It is impossible to provide precision below the gram level, making it difficult to meet the adjustment requirements that the weight error of a single dose should not exceed ±5% and the total weight error should not exceed ±3%; ③ Teachers need to manually recount each student's weighing, which is inefficient and prevents students from self-checking immediately.

[0003] While commercially available electronic scales offer digital displays, they are all general-purpose weighing scales, lacking an integrated design that considers both the appearance and the teaching context. Furthermore, they lack a closed-loop function encompassing prescription target weight, real-time weight, error assessment, and audio-visual prompts, making them unsuitable as standard teaching aids for direct application in traditional Chinese medicine dispensing training and assessment. Therefore, there is an urgent need for a teaching aid specifically designed for traditional Chinese medicine: an electronic digital display scale that retains the tactile feel of a traditional scale while providing real-time digital display, automatic error assessment, and data traceability.

[0018] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Example 1: This invention provides a teaching aid for a multifunctional electronic digital display scale for traditional Chinese medicine, such as... Figures 1 to 3 As shown, this multifunctional electronic digital display balance scale teaching aid for traditional Chinese medicine includes a balance bar 1, a weight 2, a balance pan 3, a balance rope 4, a balance knob 5, an integrated module 7, a weighing sensor 8, a buzzer 9, and an indicator light 10. The weighing sensor 8 is located at the bottom of the balance pan 3 and is used to detect the weight in the balance pan 3. The integrated module 7 is located on the balance bar 1 and includes a display screen, an audio-visual prompt module, and a communication module. The audio-visual prompt module includes a buzzer 9 and an indicator light 10. The weighing sensor 8 is communicatively connected to the integrated module 7 and is used to transmit the weight signal to the integrated module 7. The integrated module 7 is configured to calculate the current weight based on the weight signal and compare it with a preset target weight to determine the error percentage, and provide a pass or fail indication through the audio-visual prompt module.

[0021] This multifunctional electronic scale teaching aid for traditional Chinese medicine retains the external form and tactile feel of a traditional scale (scale bar 1, counterweight 2, scale pan 3, scale rope 4, scale knob 5), while deeply integrating modern electronic sensing, computing, and communication technologies to achieve intelligent teaching. In practice, when a student places the Chinese medicine into the scale pan 3, the weighing sensor 8 at its bottom accurately senses the weight change and converts the analog weight signal into a digital signal. This weight signal is transmitted in real-time to the integrated module 7 located on the scale bar 1 via a built-in communication link. The integrated module 7, as the core of data processing, can selectively use existing control information and has a pre-set processing algorithm to perform the following calculations: reading the preset target weight and allowable error percentage; comparing the current weight transmitted from the weighing sensor 8 with the target weight; and calculating the actual error percentage.

[0022] Based on the calculation results, integrated module 7 immediately makes the following determination: If the error is within the allowable range, the integrated module 7 will drive the buzzer 9 to play a qualified voice message and the current weight, while simultaneously illuminating the indicator light 10 in green. This gives the student a clear and correct signal, and the system can automatically reset to zero for the next step.

[0023] If the error exceeds the allowable range: integrated module 7 will drive buzzer 9 to play the non-compliant audio and error information, and simultaneously illuminate indicator light 10 in red. This indicates to the student that the drug dosage in scale 3 needs to be readjusted.

[0024] Throughout the process, the communication module within integrated module 7 will package the data from each weighing (such as student ID, medicinal materials, target weight, actual weight, error, and time) and wirelessly send it to the teacher's software system, enabling automatic recording, archiving, and analysis of assessment data.

[0025] In some embodiments, a thickened film-coated weighing sensor 8 and a button 6 are provided at the center of the bottom surface of the weighing pan 3. The button 6 includes a calibration button and a power button.

[0026] In this embodiment, the structure of the balance 3 has been optimized to integrate electronic components and protect them from damage during frequent operation in teaching. Specifically, a thickened support portion is provided in the central area of ​​the bottom surface of the balance 3. This thickened support portion embeds the weighing sensor 8 and the button 6, and its outer surface is covered with a high-strength protective film. This thickened design not only provides a stable and flat mounting base for the weighing sensor 8, ensuring the accuracy of the weighing reference surface, but also effectively resists impacts from accidental collisions between the balance 3 and contact surfaces such as tabletops. The outer protective film plays a crucial role in waterproofing, dustproofing, and corrosion prevention, preventing Chinese medicine powder, liquids, or cleaning agents from penetrating the sensitive electronic components, greatly improving the durability and lifespan of the teaching aid.

[0027] Furthermore, button 6 includes a calibration button and a power switch, both also protected under a diaphragm and operated by lightly touching the diaphragm. The power switch controls the power supply to and from the entire weighing system, primarily the load cell 8 and the integrated module 7. The calibration button initiates a precise calibration process during initial use or periodic maintenance: at this time, no reagents are placed in the balance pan 3, and the weight 2 should be positioned at the zero mark on the balance bar 1. The system will automatically perform sensor zero-point drift correction and angle balance calibration. Only when the integrated module 7 indicates successful calibration via buzzer 9 and indicator light 10 displays green is the teaching aid allowed to enter the formal weighing teaching program. This mechanism of prohibiting weighing without calibration ensures the accuracy and validity of all subsequent weighing data, meeting the stringent requirements of teaching assessments for measuring instruments.

[0028] This embodiment cleverly integrates the core sensing and control components into the bottom of the scale 3 and provides them with key protection, thus achieving both ease of use and measurement reliability while retaining the traditional appearance.

[0029] In some embodiments, button 6 is configured to: trigger a self-test and calibration process via the calibration button before the first weighing to ensure the zero point accuracy of the load cell 8; and the switch button is used to control the start and stop of the load cell 8.

[0030] In this embodiment, button 6 is equipped with core system control and calibration functions. Specifically, button 6 includes a calibration button and a power switch button. The power switch button is used to directly control the power supply to the load cell 8. When the user briefly presses the power switch button, the system powers on and starts, the load cell 8 begins to work and enters a standby state; a second brief press will put the system into a sleep or shutdown state, effectively saving the power of the built-in battery.

[0031] More importantly, the calibration button is specifically designed to trigger a mandatory self-test and calibration process before the first weighing or during routine maintenance. This process is the first step in ensuring the accuracy of the teaching aid's measurement. Its operation is as follows: In calibration mode, the user ensures that there is no load inside the weighing pan 3 (i.e., no load) and places the weight 2 at the zero mark position of the balance lever 1 to simulate the initial state of traditional lever balance. Then, by pressing and holding the calibration button, the system will automatically perform the following operations: initiate a self-test program to diagnose whether the weighing sensor 8 and the integrated module 7 are functioning properly; perform sensor zero-point drift correction to eliminate zero-point errors caused by changes in ambient temperature or long-term use; and perform angle balance calibration using data from the built-in angle sensor to ensure the accuracy of readings from the balance lever 1 at different tilt angles.

[0032] Only when the entire calibration process is successfully completed will the integrated module 7 issue a voice prompt indicating that the calibration is successful via buzzer 9, and indicator light 10 will turn green. At this point, the system is unlocked, allowing formal weighing operations to proceed. This prohibition on weighing without calibration eliminates systematic measurement errors caused by uninitialized equipment, ensuring the accuracy and impartiality of teaching data, especially under rigorous assessment environments.

[0033] In some embodiments, the display screen of the integrated module 7 is an OLED display window, embedded in the front of the balance bar 1, for displaying the current weight and error information in real time.

[0034] The integrated module 7 features an ultra-thin OLED display window. This window is precisely embedded in the front of the balance beam 1, its placement carefully designed to be precisely within the area where traditional balance beams typically display precision graduations. Specifically, due to the self-emissive nature of the OLED display window, the displayed content, including the current weight, target weight, and calculated error percentage, exhibits extremely high contrast and viewing angles even under indoor lighting conditions. Students no longer need to align their line of sight with the balance beam as they would with traditional graduations, thus completely eliminating parallax issues. Furthermore, the ultra-thin nature of the OLED screen allows for seamless integration into the balance beam 1 without significantly altering its overall shape, preserving the retro appearance and handheld balance of a traditional balance beam to the greatest extent possible.

[0035] During operation, the OLED display window serves as the core human-computer interaction interface, working in conjunction with the weighing sensor 8 to provide real-time data visualization. When a student places medicinal herbs into the weighing pan 3, the weight data detected by the weighing sensor 8 is transmitted in real-time to the integrated module 7. After calculation by the internal processor, key information such as the current weight m and the error percentage δ are clearly and dynamically displayed on the OLED screen. This real-time digital display mechanism allows students to intuitively and accurately read the results, eliminating the uncertainty of relying on visual estimation of traditional scales.

[0036] Furthermore, the display screen can intelligently switch its content according to different teaching modes. For example, in regular practice mode, it displays all data completely; while in a specific exam mode, it can be controlled by the teacher to display only the pass or fail result, without showing the specific weight value, thus effectively preventing cheating. This design perfectly combines the form of traditional teaching aids with the advantages of modern electronic displays, greatly enhancing the intuitiveness of teaching and the flexibility of assessment.

[0037] In some embodiments, the audio-visual prompt module is configured such that: when the error percentage does not exceed a preset error threshold, the buzzer 9 plays a prompt indicating the current weight, error, and pass / fail status, while the indicator light 10 displays green; when the error percentage exceeds the preset error threshold, the buzzer 9 plays a prompt indicating the current weight, error, and fail / fail status, while the indicator light 10 displays red.

[0038] In this embodiment, after the integrated module 7 calculates the percentage error between the current weight and the target weight, it immediately compares it with a preset error threshold. The preset error threshold is selected according to the actual situation; as an example only, the preset error threshold can be ±5%, which is common in traditional Chinese medicine dispensing.

[0039] If the error percentage is determined to be less than the preset error threshold, the buzzer 9 is triggered to clearly announce the actual weight being weighed, the calculated error value, and simultaneously provide a qualified conclusion. Meanwhile, the indicator light 10, which works in conjunction with the buzzer 9, instantly turns green.

[0040] If the error percentage exceeds the preset error threshold, the buzzer 9 will be triggered to announce the current weight, the error value exceeded, and clearly indicate that the product is unqualified, in a tone or frequency that is different from the qualified prompt. The indicator light 10 will simultaneously display a bright red color.

[0041] In some embodiments, the communication module supports bidirectional data communication with the teacher-side software system to receive prescription data and transmit weighing data packets. The transmitted weighing data packets include student ID, name of medicinal material, target weight, current weight, error percentage, and time information.

[0042] In this embodiment, the communication module integrated within the integrated module 7 constructs a two-way data bridge between the teaching aids and the upper-level teaching management system. This communication module supports a stable wireless connection with the teacher-side software system, realizing uplink and downlink data transmission, thereby completing the digital closed-loop management of teaching activities.

[0043] Specifically, teachers can edit prescriptions on their client software, typically including the student ID, herbal name, target weight, and allowable error threshold. This prescription data is then wirelessly transmitted to the integrated module 7 of the weighing scale teaching aid used by the designated student. This allows each teaching aid to receive a personalized weighing task, providing a preset standard for subsequent real-time error determination.

[0044] After each student completes a weighing operation, the integrated module 7 will proactively transmit structured weighing data back to the teacher's software system via the communication module. This weighing data contains all the information required for the assessment, specifically: student ID, name of the medicinal material, target weight m0, current actual weight m, error percentage δ, and the timestamp of the weighing operation.

[0045] This embodiment transforms the traditional, decentralized operation of weighing scales into a centralized, digital teaching process through a two-way communication mechanism. Teachers can remotely and in batches assign different practical training tasks to the entire class and receive the operation results of all students in real time. The system can automatically aggregate data packets and generate assessment reports with a single click. This not only greatly reduces the workload of teachers and achieves paperless assessment, but more importantly, it provides accurate and traceable data support for the teaching process, facilitating the evaluation of teaching effectiveness and personalized guidance, thus completely changing the teaching model and management efficiency of traditional Chinese medicine dispensing training.

[0046] In some embodiments, the steelyard teaching aid supports multiple teaching modes, including: In single-drug mode, each herb is weighed independently and automatically reset to zero after passing the weight test. The multi-drug mode supports continuous dispensing of multiple medications according to a prescription, with real-time prompts. Exam mode hides real-time weight, only indicating pass or fail, and detailed data is released after submission.

[0047] In this embodiment, the balance teaching aid integrates multiple switchable teaching modes, which are uniformly managed through its internal integrated module 7 to adapt to the needs of different teaching stages and assessment scenarios, significantly improving the flexibility and pertinence of teaching.

[0048] The single-medicine mode is suitable for beginners or for training in a single skill. In this mode, the system requires students to weigh each ingredient in the prescription independently. Once the student's weighing result for a single ingredient is deemed satisfactory, a notification will sound via buzzer 9 and indicator light 10 will turn green, at which point the system will automatically zero the data. This design simulates the process of dispensing each ingredient individually in actual prescriptions, helping students focus on mastering the accurate weighing of each herb and developing good operating habits, laying a solid foundation for subsequent complex operations.

[0049] The multi-drug mode simulates a real, complete prescription dispensing process, allowing students to continuously weigh multiple medicinal herbs in the order of the prescription. In this mode, the system does not automatically zero out after each herb is weighed correctly; instead, it allows students to perform continuous dosage adjustments, such as using the equal-volume reduction method or re-weighing each dose. Integrated module 7 provides real-time weight monitoring and prompts for each placement or removal operation, ensuring that the dosage of each herb always meets the error requirements throughout the entire process of preparing a complete decoction. This mode greatly enhances the continuity and realism of the training, developing students' ability to coordinate and operate continuously.

[0050] The examination mode is specifically designed for skills assessment, aiming to ensure fairness and seriousness. When the examination mode is activated, the integrated module 7 controls the OLED display window to hide the real-time specific weight value. Students can only know whether their current weighing result is up to standard through the voice prompts of the buzzer 9 (such as pass or fail) and the color of the indicator light 10 (green or red). This information hiding mechanism effectively prevents cheating by students peeking at each other's data. Only after the teacher performs the collection operation will all detailed weighing data for this examination (including target weight, actual weight, error, etc.) be uploaded and published for the teacher to score and analyze, thereby ensuring the authenticity and fairness of the assessment results.

[0051] Example 2: This invention provides a method for using the multifunctional electronic digital display scale for traditional Chinese medicine as described in any embodiment of Embodiment 1, which specifically includes the following steps: Step S1: Press the power button for self-test → sensor zero-point drift correction → angle sensor calibration; Step S2: The teacher sends the prescription (name of medicinal material, target weight m0, allowable error Δ%) from the software to the teaching aid; Step S3: Before the first weighing, the calibration button must be used. No Chinese medicine should be placed in the weighing pan, and the weight should be placed at the 0 mark. After the balance bar is balanced for 3 seconds, the machine will enter self-test. When the sound plays that the current weight is 0 and "qualified", and the RGB indicator light turns green, the next dispensing step can be performed.

[0052] Step S4: Student grabs medicine → puts it into the weighing pan → after the weight of the medicine in the weighing pan remains unchanged for 3 seconds, the weighing sensor samples the sample → obtains the current weight m; Step S5: Calculate the error δ = (m - m0) / m0 × 100%; Step S6: If |δ|≤Δ%, the buzzer will play the current weight and error, the RGB LED indicator will light up green, and the integrated module will beep to indicate "qualified". After that, the data will be automatically reset to zero and the student can proceed to the next step. If |δ|>Δ%, the buzzer will play the current weight and error, the RGB LED indicator will light up red, and the integrated module will beep to indicate "unqualified". The student needs to adjust the dosage of Chinese medicine in the weighing pan.

[0053] Step S7: Cache the data packet (student ID, herb name, m0, m, δ, time) and transmit it to the teacher's end; Step S8: The teacher clicks "Collect Papers" on the end, and an Excel file is generated with one click.

[0054] In some embodiments, before starting the above usage method, three teaching modes for the balance can be selected, as follows: A. Single-drug mode: Each herb is weighed independently, and the weight is automatically reset to zero after passing the test. B. Multi-drug mode: Supports teaching the dispensing of multiple drugs according to prescriptions. It can be selected in the teacher's design. When students are continuously dispensing single drugs (i.e., equal reduction and repeated weighing operation), real-time prompts can be provided. C. Exam Mode: Hides real-time weight, only displays "pass" or "fail", and publishes detailed data after submission to prevent cheating.

[0055] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
