Abstract
Description
Technical Field
[0001] This application relates to the field of measurement, and in particular to an electronic counting scale and system. Background Technology
[0002] Traditional weighing tools include platform scales that utilize the lever principle and spring scales that utilize spring deformation. Platform scales, based on the lever principle, achieve balance by adding or removing weights or moving the rider, thus determining the weight of an object. Platform scales are only suitable for situations where high weighing accuracy is not required. Spring scales utilize the deformation of a spring to measure the weight of an object, but their accuracy is also lower. With time and increased use, the spring is prone to deformation fatigue, leading to decreased measurement accuracy. Furthermore, their weighing range is relatively small, making them unsuitable for weighing heavier objects.
[0003] Traditional counting methods include manual counting and simple mechanical counters. Manual counting is extremely inefficient, especially when dealing with large quantities of items. It is not only time-consuming and labor-intensive, but also prone to errors due to human fatigue and negligence, failing to meet the demands of rapid and accurate counting in industrial production and commercial transactions. Simple mechanical counters suffer from reliability issues, easily leading to counting errors due to wear and tear or jamming of mechanical parts. Furthermore, their slow counting speed is incompatible with the fast and continuous production rhythm of modern production lines. Summary of the Invention

[0020] Figure 1 This is a schematic diagram of the structure of an electronic counting scale provided in one embodiment of this application. Figure 1 As shown, the electronic counting scale includes a base 20 and a tray 10 disposed above the base 20, with a support plate between the base and the tray. The tray 10 is used to place the part to be measured, and the base 20, in addition to providing stability, is used to install various modules required for measurement.
[0021] Figure 2 This is a schematic diagram of the module connection of an electronic counting scale in one embodiment provided in this application. Figure 2 As shown, a weighing sensor 200 is provided between the tray and the base. A main control module 100 is provided inside the base, and a display module 300 is provided on the surface of the base. The main control module 100 is connected to the weighing sensor 200 and the display module 300.
[0022] The main control module 100 acquires the total weight of multiple identical test pieces collected by the weighing sensor 200, calculates the number of the multiple identical test pieces based on the total weight and the unit weight of the test pieces, and displays the number through the display module 300.
[0023] Specifically, the main control module 100 uses the following rounding formula to calculate the number N of the multiple identical test pieces; N = int (M ÷ m + 0.5) Where M represents the total weight, m represents the unit weight, and int() represents the floor function.
[0024] The load cell 200, for example, employs a strain gauge bridge sensor. Based on the Wheatstone bridge, it uses strain gauges as variable resistor arms to form a sensing circuit, primarily used to convert mechanical strain into a measurable electrical signal. This circuit can be configured with three structures based on the number of strain gauges: a quarter-bridge, a half-bridge, and a full-bridge, with sensitivity increasing sequentially and nonlinear error decreasing accordingly.
[0025] The main control module 100, for example, uses an Arduino chip and comprises two core components: an Arduino circuit board and an integrated development environment. Its hardware uses a microcontroller (such as an ATmega328P or ARM Cortex-M3) to implement input / output control, supporting digital / analog signal processing and communication protocols such as UART and SPI. The software is written based on the Processing / Wiring architecture, using simplified C syntax to implement program compilation and uploading functions.
[0026] The display module 300 uses an LED display screen, which can display not only the quantity of the test piece, but also the total weight of the test piece.
[0027] In this embodiment, the main control module 100 acquires the total weight of multiple identical test items collected by the weighing sensor 200. Based on the total weight and the unit weight of the test items, the quantity of the multiple identical test items is calculated, and the quantity is displayed through the display module 300. The electronic counting scale in this application integrates weighing and counting functions, solving the technical problem that existing weighing equipment only has weighing function and cannot realize counting function.
[0028] Figure 3 A schematic diagram of the module connection of an electronic counting scale in another embodiment provided in this application. Figure 3 As shown, the base also has a signal processing module 400 inside. The signal processing module 400 is connected between the weighing sensor 200 and the main control module 100, and is used to amplify the analog signal representing the total weight of the multiple identical test pieces and convert it into a digital signal.
[0029] The signal processing module 400 uses, for example, the HX711 chip, a 24-bit A / D converter chip specifically designed for the high-precision weighing sensor 200. Compared with other chips of the same type, this chip integrates peripheral circuits required by other similar chips, including a regulated power supply and an on-chip clock oscillator. It has advantages such as high integration, fast response speed, and strong anti-interference, reducing the overall cost of the electronic scale and improving its performance and reliability. The interface and programming between this chip and the back-end main control module 100 are very simple. All control signals are driven by pins, without the need to program the internal registers of the chip. The input selection switch can arbitrarily select channel A or channel B, which is connected to its internal low-noise programmable amplifier. The programmable gain of channel A is 128 or 64, corresponding to full-scale differential input signal amplitudes of +20mV or ±40mV, respectively. Channel B has a fixed gain of 32 and is used for system parameter detection. The stable power supply provided within the chip can directly power the external weighing sensor 200 and the on-chip A / D converter, eliminating the need for a separate analog power supply on the system board. The clock oscillator inside the chip does not require any external components.
[0030] In this embodiment, an indicator light module 500 is also provided on the surface of the base, and the indicator light module 500 is connected to the main control module 100.
[0031] When the number of the multiple identical test pieces is greater than a preset number, the main control module 100 controls the indicator module 500 to display a red light; when the number of the multiple identical test pieces is equal to the preset number, the main control module 100 controls the indicator module 500 to display a green light; when the number of the multiple identical test pieces is less than the preset number, the main control module 100 controls the indicator module 500 to display a yellow light.
[0032] In this embodiment, the color displayed by the indicator module 500 is used to indicate the comparison result between the number of currently detected test items and the preset number, thereby improving the user experience.
[0033] In a further embodiment, a buzzer 600 is also provided on the surface of the base, and the buzzer 600 is connected to the main control module 100.
[0034] When the number of the multiple identical test pieces is greater than a preset number, the main control module 100 controls the buzzer 600 to sound a continuous alarm; when the number of the multiple identical test pieces is equal to the preset number, the main control module 100 controls the buzzer 600 to sound once; when the number of the multiple identical test pieces is less than the preset number, the main control module 100 controls the buzzer 600 to not work.
[0035] In this embodiment, the sound of the buzzer 600 is used to indicate the comparison result between the number of currently detected test items and the preset number, thereby improving the user experience.
[0036] It should be noted that the colors displayed by the indicator light module 500 and the sounds of the buzzer 600 can also be used to indicate the comparison results between the number of currently detected test items and the preset number, thereby improving the user experience.
[0037] Traditional electronic scales only have a weighing display function and lack data transmission and storage mechanisms. The data obtained from each weighing is only briefly displayed on the scale's screen, and is lost once the weighing is completed or the equipment is powered off, failing to provide effective support for subsequent data analysis, traceability, and management.
[0038] To address this technical problem, in this embodiment, the base is further provided with a communication module 700, which is connected to the main control module 100 and is used to upload measurement data to a remote database for storage. The measurement data includes the number of times the electronic counting scale counts each time.
[0039] The communication module 700 may be, for example, the ESP8266 wireless communication module 700.
[0040] The measurement data may also include the time, weight, and device number of each count by the electronic counting scale.
[0041] The communication module 700 encrypts the measurement data using an encryption protocol before transmitting it to the remote database.
[0042] In this embodiment, the collected measurement data is transmitted to a remote database in real time for storage, and the security of data transmission is ensured through an encryption protocol, thereby achieving efficient data transmission and long-term storage, providing strong support for production management and quality traceability.
[0043] In a further embodiment, data analysis tools can be used to analyze measurement data to obtain indicators such as production cycle time and production efficiency in real time, which also facilitates subsequent quality traceability and production process optimization.
[0044] In some embodiments, the base is further provided with a power module 800, which is connected to the main control module 100 and is used to supply power.

Figure 4 As shown, the electronic counting system includes an electronic counting scale 1 as described in the above embodiment and a remote database 2 that is communicatively connected to the electronic counting scale 1.
[0046] Based on the electronic counting system, including the electronic counting scale described in the above embodiments, it can solve the same technical problems and achieve the same technical effects.
[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0048] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
