Wireless distributed multi-information fusion monitoring system based on ZigBee

Abstract

The invention discloses a wireless distributed multi-information fusion monitoring system based on ZigBee, and relates to the field of infrastructure facility monitoring. The system mainly comprises three aspects of multi-information data acquisition of infrastructure facilities, intelligent processing of various information and realization of software program functions. The monitoring system is a complete system design from a hardware sensor to a software Android application, and can achieve the effect of real-time monitoring and early warning. Data such as temperature, vibration frequency and stress deformation of different infrastructure facilities are collected by utilizing multiple sensors, then the collected data are analyzed and processed by using Python, a corresponding data chart is generated, and finally, codes are written based on a java language to operate Android application software. According to the safety monitoring and early warning system, a user can know the real-time safety operation state of infrastructure facilities such as a bridge and a derrick in time, potential hidden dangers can be searched and eliminated through information feedback, the safety detection efficiency of a project can be improved, the reliability is high, and the universality is high.

Description

technical field [0001] The invention relates to the field of safety monitoring of bridges, derricks and other infrastructure facilities, specifically a ZigBee-based wireless distributed multi-information fusion monitoring system 1-1. Background technique [0002] In recent years, my country's infrastructure facilities have developed rapidly, and its infrastructure capacity ranks among the top in the world. However, with the passage of time, more and more infrastructure facilities such as bridges and derricks have reached the design reference period ahead of schedule due to structural damage due to geological disasters or man-made damage. At the same time, there are many potential safety hazards in bridge engineering due to various factors such as overloaded transportation of vehicle loads, environmental corrosion, and improper supervision. Under actual working conditions, equipment structures such as factory production equipment, construction site steel frame structures, la...

Problems solved by technology

[0003] Patent CN 110111552A discloses a ZigBee-based multi-point and multi-channel strain wireless monitoring system for bridges. This system combines ZigBee technology, emphasizing the reliability of the system, and solves the shortcomings of traditional methods with high cost

However, insufficient consideration is given to the stability and anti-interference aspects of the system's data collection, and the lack of data cleaning content may cause the sensor to consume a lot of energy due to storing too much data, which affects the life of the sensor, so that it cannot monitor bridge problems well.

[0004] In recent years, many monitoring systems have emerged one after another, but the scope of monitoring is not extensive, and the universality is not ideal. At the same time, there is a lack of consideration for the stability and reliability of the monitoring system, and there is also a lack of control over sensor energy consumption, resulting in high power consumption. There are many shortcomings such as high monitoring cost, so a ZigBee-based wireless distributed multi-information fusion monitoring system is proposed 1-1
