The first embodiment is as follows:

the memory is used for storing a computer program comprising program instructions, the processor is configured for invoking the program instructions, with reference to fig. 1, for performing the following method:
s1: dividing the weighing surface into at least two functional areas, and setting a control instruction of each functional area;
preferably, the functional area comprises a weighing area and at least one interaction area; wherein the interactive areas are respectively arranged at the periphery of the weighing area. The control instruction of the weighing area comprises weighing; the control instructions of the interactive area include, but are not limited to, unit conversion, peeling, clearing and counting.
Specifically, the weighing area is the area with the largest area in all the functional areas, the weighing area can be arranged in the center of the weighing surface, and the weighing area mainly achieves the weighing function of the electronic scale foundation. The interactive zones are arranged around the weighing zone, for example, in fig. 2, 3 interactive zones are respectively arranged side by side below the weighing zone. The interactive areas mainly realize interactive functions in the electronic scale, such as unit conversion, peeling and other interactive functions, and each interactive area triggers one function. For example, in fig. 2, the interactive area a starts the unit conversion function, and the interactive area B starts the peeling function. The control instruction of the functional area is used for controlling the electronic scale to execute corresponding control operation. The pressure includes the weight of the weighing object itself or the pressure applied by the user to the weighing surface.
S2: acquiring pressure data sensed by the full-bridge module, and analyzing according to the pressure data to obtain the projection position of the pressure on the weighing surface;
in particular, the projected position of the pressure on the weighing surface, i.e. the center of gravity of the pressure, can be analyzed to identify the functional zone where the pressure is mainly applied.
S3: obtaining a functional area to which the pressure on the weighing surface belongs according to the projection position;
s4: and executing the control instruction corresponding to the functional area.
Specifically, when the electronic scale detects which functional area the gravity center of the pressure falls into, the electronic scale executes the control instruction corresponding to the functional area, for example, when the user presses the interactive area a, the electronic scale is controlled to perform unit conversion when the gravity center of the pressure falls into the interactive area a. When the user presses the interaction area B, the gravity center of the detected pressure falls into the interaction area B, and the electronic scale is controlled to perform peeling operation.
The existing electronic scales are generally controlled through keys, the electronic scales are not waterproof due to the adoption of the key design, and the keys are easily polluted due to dirt on hands in the process of pressing the keys by hands, so that the service life of the keys is greatly reduced, the sensitivity of the keys is reduced, and the usability of the electronic scales is reduced. Therefore, the electronic scale provided by the embodiment can realize the human-computer interaction function by pressing different positions of the weighing surface, reduce the keys of the weighing surface, reduce the manufacturing cost and simultaneously ensure the attractive appearance of the electronic scale.

and when the functional area to which the pressure on the weighing surface belongs is detected to be the weighing area, executing a control instruction corresponding to the weighing area by combining a control instruction of the last interactive area or default setting.
Specifically, when the functional area to which the current pressure belongs is detected to be the interactive area, which indicates that the user wants to execute the control instruction of the interactive area, the processor may directly execute the control instruction, for example, execute peeling, unit conversion, and the like. And when the processor detects that the functional area to which the current pressure belongs is the weighing area, the processor executes corresponding operation on the current weighing data by combining the control instruction or default setting of the last interactive area.
For example, when a peeling operation is performed, if a pressure is detected in the weighing area, the weighing cannot be performed immediately, and the weighing is performed after the peeling operation is completed. Therefore, a user can execute the control instruction corresponding to the interactive area before weighing, and the weighing area is triggered to weigh after the control instruction is executed. Or when the control instruction corresponding to the interactive area is not executed, weighing according to default settings.
