By using the method of simulating buttons to select products, it is possible to complete the product identification result confirmation and label printing process only by operating the scale platform with gestures. According to the operation mode of pressing and identifying the scale platform by different users, the formulation corresponds to the operation mode one by one. The unique analog button realizes the simplification of the product identification and weighing process on the scale platform, thus greatly reducing the frequent movements of the measurer to raise his hand, so that the measurer can complete the product measurement process more easily.

Specifically, in this embodiment, the user operates the identified weighing platform within 3 seconds after the recognition result is displayed to increase the weight of the identified weighing platform, and the weight returns to the weight before the gesture operation within the response time. When the weight increment exceeds the first weight threshold 20g, the duration of the change in the weight increment is obtained and recorded; according to the duration of the change, the user's operation mode on the identification scale platform is determined. According to the sensed operation modes, key instructions corresponding to different operation modes are determined.

According to the sensed operation mode, determining the instructions corresponding to different operation modes includes, when the duration of the weight change of the weighing platform is within the first time length range, the first time length range is 100ms to 300ms, when the user When pressing the weighing platform so that the weight change of the weighing platform lasts longer than 100 ms and less than 300 ms, it is determined that the operation mode is the first button command.

Then it is determined that the operation mode corresponds to the second button instruction.

Specifically, in this embodiment, as shown in FIG. 2, information interaction is carried out by adopting the above-mentioned key command input mode, and the product identification result is obtained, and the key command to be input is confirmed according to the product identification result; According to the operation mode of the station, input the corresponding key command according to the sensed different operation modes; according to the key command, execute the interaction process corresponding to the key command to perform information interaction, when the key command is empty , information interaction is performed through other input devices. According to the button instruction, execute the interaction process corresponding to the button instruction; the button instruction includes the first button instruction and the second button instruction; according to the first button instruction, execute the interaction process corresponding to the button instruction For, printing the product label information of the first recognition result; according to the second key command, executing the interaction process corresponding to the key command is, for printing the product label information of the second recognition result.

As shown in Figure 3 and Figure 4, specifically in this embodiment, when the product is placed on the weighing platform and the product recognition result obtained by recognition is displayed to the user through the interactive terminal, at this time the recognition scale completes the product identification and enters the product confirmation state, while the weighing platform is in the state of obtaining user button instructions within three seconds, the weighing system receives the operation mode of the user pressing the identification weighing platform, and the user presses the finger on the identification weighing platform, and the weight sensor will obtain The weight change value and weight change duration of the weighing platform of the identification scale are output to the host of the identification scale; the weight change value of the identification scale host weighing platform and the duration of weight change determine the operation mode for the user to press the identification weighing platform, any of the The simulated keys are preset to have a corresponding operation mode of pressing the weighing system by the user's fingers, and the host of the identification scale sends the corresponding key command to the interactive terminal for the operation mode. The interactive terminal includes a touch display screen and a label printing device, and the user can also click and print product label information corresponding to the product through the touch display screen, and print out the label printing device through the label printing device Paste on the product.

Wherein the first simulated button presets the operation mode for the user to press the weighing system as follows: the user presses the weighing system so that the duration of the weight change of the weighing system is within a preset time range. Or the user presses the weighing system so that the weight change value of the weighing system exceeds a preset time threshold. Specifically, when the user taps the weighing platform within three seconds and the weight change value obtained by the weighing platform is greater than 20g, and the duration of the weight change is greater than 100ms but less than 300ms, the recognition scale host sends a button command to print the preferred product to the An interactive terminal, the interactive terminal prints the label information of the preferred commodity. When the user lightly presses the weighing platform within three seconds and then releases the hand, and the weight change value acquired by the weighing platform is greater than 20g, and the duration of the weight change is greater than 1000ms, the host of the identification scale sends a button command to print the next selected product to the interactive terminal, The interactive terminal prints the label information of the second-selected commodity. After the weighing platform is in the state of obtaining the user's button command for 3 seconds, it will exit this state. After obtaining the product identification result, if the weighing platform does not obtain the user's operation method for the identified weighing platform, click on the touch screen or enter the keyboard Information interaction is carried out in the form of traditional keyboard input or touch screen input to complete the confirmation of the recognition result. The label information includes the name of the commodity category, the barcode corresponding to the commodity category, the weight of the commodity, the unit price of the commodity, and the total price of the commodity , label printing time and other information.

The above weighting time range (100ms to 300ms), weight change value (20g) and weight change time threshold (1000ms) are not limited to this embodiment, because in the actual application process, different types of goods will be divided into different areas, and in different The product area will have identification scales corresponding to its product category, so the above settings need to be adjusted according to the type of product being measured. The weighting time range setting of the recognition scale is different.
