Technical Field
The invention belongs to the technical field of electronic scales, and particularly relates to an intelligent electronic scale.
Background
An electronic scale is a kind of weighing apparatus, and is a tool for measuring the mass of an object by using hooke's law or the principle of lever balance of force. According to the structural principle, the mechanical scale can be divided into three categories, namely a mechanical scale, an electronic scale and an electromechanical combination scale. The electronic balance is mainly composed of three parts of a bearing system (such as a scale pan and a scale body), a force transmission conversion system (such as a lever force transmission system and a sensor) and a value indicating system (such as a dial and an electronic display instrument). When an object is placed on the scale, pressure is applied to the sensor, which deforms elastically, causing a change in impedance and, at the same time, a change in the applied excitation voltage, outputting a changing analog signal. The signal is amplified by the amplifying circuit and output to the analog-to-digital converter. The digital signals converted into the signals convenient for processing are output to the CPU for operation control. The CPU outputs such results to the display according to the keyboard commands and the program. Until such a result is displayed.
When the existing intelligent electronic scale is used, particularly when quantitative liquid needs to be filled into the soft bag during weighing, due to the fact that the existing electronic scale does not have a structure capable of being used for pulling and holding the bag, personnel are needed to pull and hold the bag, the whole weighing weight is reduced when the bag is pulled and held upwards, and weighing accuracy is affected.
