Pointer, LCD double-display electronic scale and working method thereof

Abstract

The invention relates to a pointer, an LCD double-display electronic scale and a working method of the electronic scale. The electronic scale comprises a weighing sensor, the rotating pointer arranged on a scale panel and a power supply module supplying power to the electronic scale. The electronic scale is characterized in that the weighing sensor is connected with a CPU through an AD switching circuit; the CPU is connected with an LCD through an LCD drive circuit; the CPU drives a stepping motor through a stepping motor drive circuit, and the stepping motor is used for driving the pointer to rotate. According to the pointer, the LCD double-display electronic scale and the working method, the double-display function is achieved; the pointer display is achieved by driving the pointer to rotate through the stepping motor, so that the indication function is achieved, and the defect that in the prior art, display is achieved by rotating a dial through elastic deformation is overcome. The LCD double-display electronic scale can also serve as a warning device when the electronic scale is not used, and multiple purposes of the electronic scale are achieved.

Description

technical field [0001] The invention relates to the technical field of electronic scales, in particular to an electronic scale with dual displays of pointer and LCD and its working method. Background technique [0002] At present, the electronic scales on the market all use LCD or LED as the display to read the weighing data, while the pointer type reads the data are all spring type scales and the pointer is fixed and the digital panel is rotated to read the value. This kind of pointer display is through Elastic deformation is used to realize the rotation of the dial, and the service life depends on the quality of the spring, which not only has a short service life, but also has low precision. In addition, for users, some of them are used to reading LCD data, and some users are used to reading pointer data. However, there is no electronic scale that displays pointer and LCD at the same time on the market. Therefore, it is necessary to provide a multifunctional electronic sca...

[0002] At present, the electronic scales on the market all use LCD or LED as the display to read the weighing data, while the pointer type reads the data are all spring type scales and the pointer is fixed and the digital panel is rotated to read the value. This kind of pointer display is through Elastic deformation is used to realize the rotation of the dial, and the service life depends on the quality of the spring, which not only has a short service life, but also has low precision

In addition, for users, some of them are used to reading LCD data, and some users are used to reading pointer data. However, there is no electronic scale that displays pointer and LCD at the same time on the market. Therefore, it is necessary to provide a multifunctional electronic scale with dual displays. market demand
