Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] ZigBee wireless sensor nodes are deterministically deployed to leak-prone locations according to the monitoring environment. After the sensor nodes are deployed, a wireless sensor network will be established for concentration collection. The node sends the concentration of the target gas in the monitoring area to the ZigBee coordination module in the intelligent monitoring center after filtering in real time. The coordination module organizes and sends the data to the intelligent monitoring center through the serial port to complete data fusion and anomaly detection, and sends the real-time data to the remote cloud server. When a leak occurs, the intelligent monitoring center will send an alarm message to the employee's mobile phone to ensure the safety of life and property. The structure of the wireless monitoring system for dangerous gas leakage in industrial envi...

Abstract

The invention discloses a ZigeBee-based industrial environment dangerous gas leakage detection system. The invention can be mainly divided into three parts: a wireless sensor network composed of sensor nodes, a data processing center of an ARM platform, and a data storage and monitoring center based on a cloud server. In order to improve the installation flexibility and detection efficiency of the system, and reduce deployment costs and power consumption, ZigBee technology is used to build a wireless sensor network, and the solar charging function based on Texas Instruments' single battery management chip is added to the sensor nodes. The data processing center uses the ARM processor as the control core to realize data reception, leakage judgment, data upload to the cloud server, early warning SMS sending, and data display synchronously. Combined with the homogeneous sensor data fusion algorithm and fragment anomaly detection algorithm, the industrial Fast and accurate alarm of environmental hazardous gas leakage.

Description

technical field [0001] The invention belongs to the field of wireless sensor network monitoring, in particular to a ZigeBee-based industrial environment dangerous gas leakage detection system. Background technique [0002] Globally, a large amount of combustible gases, toxic gases, and organic vapors such as benzene and aldehydes are produced every year in industries such as gas, petroleum, chemical industry, and metallurgy. The leakage of these dangerous gases causes a large number of accidents every year, causing huge casualties, economic loss and environmental pollution. As the State Administration of Work Safety continues to tighten the safety requirements for chemical and hazardous chemical processing, the amount of gas detection instruments in the chemical and hazardous chemical processing field is increasing year by year. [0003] The current leak detection system can be roughly divided into two categories: mobile and fixed. Among them, there are two types of mobile ...
