Problems solved by technology

[0003] Moreover, due to the invisibility of toxic gas, it moves quickly and changes shape at any time, so it is difficult to monitor the scope of its leakage area.
In most toxic gas leakage accidents, different types of chemical gases will easily leak at the same time, causing gas mixing

Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0047] The industrial sensor network of the present invention is based on the poisonous gas boundary detection algorithm of node positioning, and the steps are as follows:

[0048] Step 1: DeGas_AnchorNode broadcasts information packets (coordinates, ID, minimum hop count, status indication), DeGas_AnchorNode refers to the anchor node used for poison gas detection:

[0049] DeGas_AnchorNode broadcasts data packets containing its own coordinate information to its neighbor nodes in a flooding manner in the sensor network, including {coordinates (x, y), minimum hop number hop, node ID, status indication}, where the minimum hop number hop Initialized to 0. The receiving node records each arriving ...

Abstract

The invention discloses a poison boundary detection method of an industrial sensor network based on node positioning. The method comprises the following steps: 1) a DeGas_AnchorNode broadcast information comprises {coordinates (x,y), the minimum hop count hop, the node number ID, status indication}; 2) an average hop distance between the DeGas_AnchorNodes is computed; 3) a coordinate of the DeGas_AnchorNode is computed; 4) an inner boundary node and an outer boundary node are determined; 5) the planarization is performed on a poison monitoring network topological structure by use of a GG planarization algorithm; 6) an outer boundary region is constructed; and 7) an outer boundary region area is computed. By use of the poison boundary detection method based on node positioning provided by the invention, the efficiency of the sensor in the industrial application is improved, the node positioning and poison gas boundary detection algorithm are combined in innovation, the consumption of the node cost is reduced, and the detection accuracy of the poison gas boundary detection is increased.

Description

technical field [0001] The invention relates to a poisonous gas boundary detection method based on node positioning of an industrial sensor network, which belongs to the technical field of gas detection. Background technique [0002] In large petrochemical plants, the monitoring of toxic gases is a key issue, which warns relevant personnel of potential risks and prevents explosions. Industrial wireless sensor networks (IWSNs) have the advantages of easy deployment, small size, high energy efficiency, and flexible sensing nodes, becoming a promising approach for petrochemical plant designers and manufacturers to solve a key problem, namely toxic gas monitoring. [0003] Moreover, due to the invisibility of toxic gas, it moves quickly and changes shape at any time, so it is difficult to monitor the scope of its leakage area. In most toxic gas leakage accidents, different types of chemical gases will easily leak at the same time, causing gas mixing. [0004] Then, how to accu...
