Abstract

The invention discloses a networking intelligent digital weighing sensor, which comprises a simulation weighing sensor, a temperature sensor, an analog-to-digital converter, an electronic data table unit, an information processing unit, a communication unit and a power supply module, wherein the electronic data table unit conforms to IEEE1415.2 standards, the simulation weighing sensor is used for collecting weight data, the temperature sensor is used for collecting real-time temperature data, the analog-to-digital converter is used for converting the weight data and the real-time temperature data into corresponding digital signals, the information processing unit is used for outputting weight data after compensation calibration, and the communication unit is provided with a universal serial interface and a communication interface compatible with IEEE1415.2. The technical scheme conforms to requirements of the IEEE1415.2 standards on an independent interface of the intelligent sensor and simultaneously solves the problems that in the sensor manufacture process, the precision is difficult to improve, the production efficiency is low, the finished product rate is low and the like, and in addition, the digital weighing sensors with the same resolution ratio can be produced in batches.

Description

technical field [0001] The invention relates to a weighing sensor, in particular to a networked intelligent digital weighing sensor Background technique [0002] Load cells are the most critical components of electronic weighing instruments and various weighing systems. Its function is to convert the weight into an electronic signal, so it determines the accuracy of electronic scales and weighing systems. The intelligence and networking of weighing sensors is the development direction and the requirement of modern information technology development. Networked smart sensors can not only bring convenience to users, but also have a wider range of applications, and are more conducive to their own development. [0003] At present, the load cell is dominated by analog load cells, supplemented by digital load cells. [0004] The analog load cell generally includes an elastic body and a strain gauge. The weight of the weighing item deforms the elastic body. The strain gauge conve...
