A blockchain-based bridge construction monitoring system

Abstract

The invention discloses a bridge construction monitoring system based on block chain, which includes RFID tags, RFID read-write equipment and computer monitoring terminals. The RFID read-write equipment includes antennas, signal processing units, microprocessors and wireless modules. The remote communication is formed between the RFID reading and writing equipment and the computer monitoring terminal. The signal processing unit includes a receiving signal filtering circuit, a dual-channel amplification and regulating circuit, a fault protection circuit and a digital decoding circuit. The receiving signal filtering circuit performs the output signal of the coupling coil L1. Automatic tuning to avoid the center frequency shift or frequency characteristic distortion of the received signal; the dual-channel amplifying and regulating circuit reduces the interference between digital and analog existing in the post-stage circuit processing, and uses a double-T filter to eliminate power supply noise, and can effectively eliminate external electromagnetic waves. Noise, the fault protection circuit discharges the abnormal high voltage in time when the continuous surge voltage occurs, which plays a good role in protecting the RFID reading and writing equipment.

Description

technical field [0001] The invention relates to the technical field of bridge construction monitoring, in particular to a blockchain-based bridge construction monitoring system. Background technique [0002] In the bridge construction site, the density control of construction personnel and the scheduling of construction equipment are realized through positioning monitoring. With the gradual deepening of blockchain and its application in bridge construction monitoring, the bridge construction monitoring system based on blockchain realizes the monitoring of bridge construction in different areas. Distributed storage and point-to-point transmission of on-site positioning data make bridge construction monitoring more convenient and more complete. At present, bridge construction mainly uses RFID equipment to monitor the location of personnel and equipment. RFID equipment collects the information of RFID electronic tags set on construction personnel and construction equipment thro...

AI Technical Summary

Problems solved by technology

When RFID equipment reads tag information, it needs to detect small input signals very sensitively, and the noise generated by the internal circuit of RFID equipment will cause the entire system to be unstable, such as power supply noise, electromagnetic noise and interference between digital and analog Wait

External lightning or static electricity will also bring high-voltage spike noise to the internal circuit of RFID equipment to block the normal signal reception, and even damage the equipment, affecting the normal operation of the entire bridge construction monitoring system
