Problems solved by technology

Generally speaking, when a user (such as an engineer) uses a measuring tool to measure and calculate an area or volume, he cannot immediately know the measurement result of the area or volume after the measurement is completed, but must use the memorized Formulas, calculations in white lines to solve area or volume
[0004] However, since there are definite solution formulas for the area and volume of various specific shapes, if all of them need to be recited by the user, it is inevitable that there will be mistakes in recitation, resulting in errors in the calculated values; in addition, users also have It is possible to accidentally omit the input size parameters. For example, if you want to calculate the volume of a cuboid, you only input the length and width parameters, but forget to input the height parameter. It is known that the computer does not have a mechanism to help the user check whether the input value is reasonable. It is not very good Ideal; in addition, the user usually needs to recite or copy the values ​​​​to be input first, and then input them into the computer one by one, without the function of combining measurement tools

Embodiment Construction

[0046] Please refer to FIG. 1 for a functional block diagram of the computing device 1 in this embodiment, which shows that the computing device 1 mainly includes a storage unit 11 , an input unit 12 , a display unit 13 , and a control unit 14 . Wherein, the storage unit 11 is built-in to store a plurality of calculation formulas 111, and each calculation formula 111 is made up of at least two parameters and at least one logical operator, as shown in the calculation formula table in Figure 2, the storage of the present embodiment Unit 11 stores various area calculation formulas and volume calculation formulas. For example, the calculation formula for solving the area of ​​a triangle that can be retrieved from the storage unit 11 is: "B×H÷2", where B is the base of the triangle ( bottom), H is the height of the triangle; and the formula for calculating the volume of a cube is: "L×W×H", where L is the length, W is the width, and H is the height. and so on. Of course, the calcul...

Abstract

This invention relates to an automatic computing device of weights and measures and a method, among which, the device includes a storage unit, an input unit, a display unit and a control unit. Said storage unit has many operation formulas stored in it when it receives an input signal of a selected operation formula, it will fetch a corresponding operation formula from the storage unit to be displayed by the display unit, then receives the input values corresponding to the parameters in terms of the definition of the operation formula, the control unit caries out mathematical logic operation based on the operation formulas and input value to compute and display an operation result.

Description

technical field [0001] The invention relates to a consumer electronic device, in particular to a weights and measures automatic calculation device and method with a calculation function. Background technique [0002] As we all know, computers have computing functions for basic operations such as addition, subtraction, multiplication, and division, or for more complex high-order operations in order to calculate required values. [0003] When you want to calculate the measurement results through the computer, for example, you want to calculate the area or even volume of a specific object, the user needs to input the size parameters one by one according to the formula recited from memory, and then the computer calculates the specific object. area or volume. Generally speaking, when a user (such as an engineer) uses a measuring tool to measure and calculate an area or volume, he cannot immediately know the measurement result of the area or volume after the measurement is comple...
