Remote data wireless transmission weighbridge system based on LoRa technology

Abstract

The invention discloses a remote data wireless transmission weighbridge system based on a LoRa technology. The remote data wireless transmission weighbridge system comprises a weighbridge weighing platform, RFID reading and writing vehicle equipment, an infrared detector, an A / D data acquisition terminal, a LoRa data transmitting module, a LoRa data receiving module, and a data terminal, wherein the weighbridge weighing platform is used for testing a total weight of a vehicle, the RFID reading and writing vehicle equipment is used for reading information of the vehicle and a driver, and an infrared detector is used for checking whether the vehicle is completely on the weighbridge weighing platform; the weighbridge weighing platform is connected with the A / D data acquisition terminal, two microcontrollers control the LoRa data transmitting module and the LoRa data receiving module respectively, and the LoRa data transmitting module and the LoRa data receiving module perform bidirectional interaction; and received data is displayed on the data terminal finally. The remote data wireless transmission weighbridge system has the advantages of unattended operation and improved working efficiency.

Description

technical field [0001] The invention relates to the field of weighbridge technology, in particular to a LoRa technology-based remote data wireless transmission weighbridge system. Background technique [0002] With the rapid development of science and technology and economy, the research and development and use of weighbridges are playing an increasingly important role in industrial production. Traditionally, in the process of using the weighbridge, if the instrument is placed next to the weighbridge to read the data at a close distance, manual guards are required day and night, which wastes manpower, and it is necessary to build a scale room, wasting material and financial resources. Therefore, it is very necessary to be able to read the data of the weighbridge remotely. However, considering that the environment where the weighbridge is located is relatively harsh and cannot be wired in large quantities, it is impossible to use wired methods to achieve long-distance data t...

AI Technical Summary

Problems solved by technology

However, considering that the environment where the weighbridge is located is relatively harsh and a large number of wiring cannot be used, it is impossible to use wired methods to achieve long-distance data transmission. Therefore, using wireless methods for long-distance data transmission has become a necessary choice.
