Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing.

[0011] The invention is a self-organized multi-hop wireless sensor network system for poisonous gas detection, which is composed of a large number of wireless terminals and a wireless receiving end machine. The wireless terminal is paired with the toxic gas sensor, connected to the control unit through the RS-232 serial port, responsible for reporting the detection results of the paired toxic gas sensor, and relaying and forwarding for other wireless terminals around it. The wireless terminal is powered by a battery; wireless The receiver is responsible for system coordination, display and storage of sensor detection status information, multi-node information fusion processing for all reported data, analysis of toxic gas leakage sources and diffusion trends, and power supply through wired methods.

[0012] The self-organized multi-hop wireless sensor network composed of the...

Abstract

The invention discloses a wireless sensor network system used for toxic gas detection which is a self-organized multi-hop wireless sensor network system for toxic gas detection consisting of a large-volume toxic gas sensor, a large-volume wireless terminal and a wireless receiving terminal. The toxic gas sensor is responsible for signal acquisition and processing on the front end; the wireless terminal is matched with the toxic gas sensor, connected with a control unit through a RS-232 serial port, responsible for reporting the detection result of the toxic gas sensor matched with the wireless terminal, and makes relay forwarding for other wireless terminals around the wireless terminal; the wireless receiving terminal is responsible for the coordination of the system, the display and the storage of the detection state information of the sensor, makes multi-node information fusion to all the reporting data, analyzes the leakage source of toxic gas and the diffusion trend thereof, and is supplied through a wire DC power supply mode. The wireless sensor network system adopts a multi-hop relay forwarding mechanism, effectively overcomes the disadvantages that the wireless transmission has limited distance and is easy to block, and is suitable for various complicated application environments.

Description

Technical field: [0001] The invention relates to a wireless sensor network, in particular to a wireless sensor network system for poisonous gas detection. Background technique: [0002] The existing detection of toxic gas is usually when the toxic gas detector is used alone, and the existing toxic gas detector is used alone, and the leakage source and diffusion trend of the toxic gas cannot be determined. Invention content: [0003] The purpose of the present invention is to provide a wireless sensor network system for toxic gas detection. [0004] The invention aims to solve the problem that the leakage source and diffusion trend of the toxic gas cannot be determined when the existing toxic gas detector is used alone. [0005] The technical solution of the present invention is: the present invention is an self-organized multi-hop wireless sensor network system comprising toxic gas sensors, wireless terminals and wireless receiving terminals, which consists of a large num...
