The Design of Intelligent Weighing Apparatus Monitoring Based on Internet of Things

Abstract

In order to improve the efficiency of the metrology department and promote the development of intelligent weighing apparatus, this paper proposes the design of the weighing monitoring system from two aspects of measurement system and monitoring system. In the measuring end, STC89C52 microcontroller is used as the main control chip to achieve the accurate measurement of pressure. The temperature drift of the pressure sensor is reduced by using the pressure sensor temperature compensation algorithm based on the combination of Lagrange difference and least square. The monitoring system uses the upper computer, the Wi-Fi module and the Android mobile phone to remotely monitor the measurement system intuitively, receives and displays the measurement data in real time, and can invoke the historical data. The system realizes the real-time monitoring of the weighing instrument and makes the weighing instrument become the integrated remote monitoring equipment, which has many functions such as data analysis, remote diagnosis and remote operation. This design is of great significance to study the intelligent weighing field.
