[0038] Reference Figure 1 This is a flow chart of an electronic scale initialization control method provided in an embodiment of the present application, the method comprising steps S110 to S120.
[0039] Step S110, in response to the device being powered on, obtaining the current position information of the electronic scale, and calculating the target gravity coefficient corresponding to the current position according to the position information and the corresponding elevation value;
[0040] Step S120: adjusting the gravity coefficient of the electronic scale to the target gravity coefficient.
[0041] In some possible implementations, since the gravity coefficient of an object varies with its position on the earth's surface and its height from the ground, when the electronic scale is powered on, the current position information is obtained through GPS positioning, and the position information includes latitude and elevation values, where the elevation value is the distance between the electronic scale and the earth's surface; the target gravity coefficient corresponding to the current position of the electronic scale is calculated based on the latitude and elevation values; and the calculated target gravity coefficient is used as the gravity coefficient when the electronic scale is weighed. The target gravity coefficient is calculated according to the following formula:
[0042] g(h)=g(0)[1-(2h / R)],
[0043]
[0044] Where h represents the elevation value in the location information, g(h) represents the target gravity coefficient, g(0) represents the gravitational acceleration on the earth's surface, and R represents the radius of the earth. Indicates the latitude in the location information.
[0045] like Figure 2 As shown, in some possible implementations, the electronic scale initialization control method provided in the embodiment of the present application further includes:
[0046] Step S210, obtaining a plurality of weighing objects of known weight, and weighing the weighing objects based on the target gravity coefficient to obtain weighing values;
[0047] Step S220: calibrate the reading of the electronic scale according to the weighed value and the actual weight value until the reading is equal to the actual weight value.
[0048] In this embodiment, the electronic scale sometimes needs to be calibrated in daily use, and the process of calibrating the electronic scale includes: obtaining a number of weighing objects of known weight, weighing the weighing objects based on the target gravity coefficient, and obtaining weighing values; calibrating the weighing values of the weighing objects and their actual weight values until the reading of the electronic scale is equal to the actual weight value. The weighing objects can be any items of known weight, such as powder bags of known weight.
[0049] like Figure 3 As shown, in one embodiment, step S210 includes:
[0050] Step S310, receiving a selection instruction of a plurality of weighing ranges, and determining a corresponding target range according to the selection instruction;
[0051] Step S320: weighing the object to be weighed based on the target measuring range and the target gravity coefficient.
[0052] In some possible implementations, in order to prevent the user from lacking the weighing object within the range of the electronic scale, the electronic scale can be set with multiple ranges so that the user can select a suitable range or a combination of multiple ranges according to the weight of the weighing object, thereby weighing the weighing object based on the selected target range combined with the target gravity coefficient.
[0053] For example, if the user currently holds 0.5g and 1g of powder, and the existing electronic scales generally have a range of 0-7.5g and 0.75-1.5g, the user can choose a 0.5g weight and adjust the range of the electronic scale to 0-7.5kg; or choose a 1g weight and adjust the range of the electronic scale to 0.75-1.5g; or choose 0.5g and 1g and adjust the range of the electronic scale to 0.75-1.5g. In addition, it is not ruled out that the electronic scale does not have a single range that meets the user's needs, and multiple ranges are required, and the weight is calculated in combination with an algorithm.
[0054] like Figure 4 As shown, in one embodiment, step S220 includes:
[0055] Step S410, calculating the difference between the weighed value and the actual weight value to obtain the reading adjustment amount that needs to be adjusted;
[0056] Step S420: calibrate the reading of the electronic scale based on the reading adjustment amount.
[0057] In some possible implementations, the process of calibrating the electronic scale includes: calculating the difference between the weighing value and the actual weight value to obtain the reading adjustment amount that the electronic scale needs to adjust; and then calibrating the reading of the electronic scale according to the reading adjustment amount. For example, if the weighing value of the electronic scale is 0.45kg, and the actual weight value of the weighed object is 0.5g, the difference is 0.05g, and the reading of the electronic scale needs to be adjusted to increase by 0.05g so that the weighing value of the electronic scale is equal to the actual value of the weighed object, and then the calibration is completed.
[0058] In response to the device being powered on, the embodiment of the present application obtains the current position information of the electronic scale, and calculates the target gravity coefficient corresponding to the current position based on the position information and the corresponding elevation value; adjusts the gravity coefficient of the electronic scale to the target gravity coefficient, thereby adjusting the gravity coefficient of the electronic scale according to the position, so as to achieve the effect of eliminating errors when the same electronic scale weighs objects at different positions and heights above the ground.

[0061] The coefficient calculation module 110 is used to obtain the current position information of the electronic scale in response to the device being powered on, and calculate the target gravity coefficient corresponding to the current position according to the position information and the corresponding elevation value;
[0062] The adjustment module 120 is used to adjust the gravity coefficient of the electronic scale to the target gravity coefficient.
