Electronic weighing device equipped with wireless control terminal

Abstract

The invention relates to the technical field of electric and electronic equipment, especially an electronic weighing device equipped with a wireless control terminal. The device comprises a weighing body and an intelligent client. The weighing body comprises a housing, and the back surface of the housing is provided with a battery box. The battery box is provided with a battery, and the interior of the housing is provided with a bearing plate. The back surface of the plate is fixedly provided with a chip substrate, connected with the battery, through a screw. The chip substrate is connected with a sensor unit, and the sensor unit is connected with the chip substrate. The sensor unit comprises an upper fixing part, a sensing element, and a lower stretching element. The chip substrate is provided with a CPU, an OP amplification circuit, an AD conversion circuit, a wireless signal transmitting unit, an excessively low voltage automatic power-off circuit, a switch, an indicating lamp, a battery charging interface, and a waterproof power jack. The wireless signal transmitting unit performs wireless communication with the intelligent client. The device is reasonable in structural design,achieves the displaying of the weighing-related data at the intelligent client, and solves problems that the display is dull, the number of functions is small and the display screen and function keysof the weighing body are liable to be damaged.

Description

technical field [0001] The invention relates to the technical field of electrical and electronic equipment, in particular to an electronic weighing device with a wireless control terminal. Background technique [0002] The traditional electronic crane scale is the most important weighing tool at present. It measures accurately, reads intuitively, and is easy to use, and is favored by merchants. Its principle is: the object pulls the sensor, and the small signal of the sensor is transmitted to the OP amplifier circuit, then to the A / D conversion circuit, and then through the display circuit, function circuit, function keys, and finally the display screen on the weighing body ( LCD / LED) display weighing information. Although the electronic crane scale is easy to use, it has a single display and a single function. The display and function buttons are integrated with the weighing body, which is easy to be damaged. For example, the display is easy to wear and blur, and the funct...

Problems solved by technology

Although the electronic crane scale is easy to use, it has a single display and a single function. The display and function buttons are integrated with the weighing body, which is easy to be damaged. For example, the display is easy to wear and blur, and the function buttons are easy to be damaged. Damage, short service life, and the traditional electronic scale is limited by the power supply voltage, it must have enough power supply voltage before it can be used. If the battery voltage is too low, the weighing will be inaccurate, which will damage the interests of consumers
