Problems solved by technology

Once a toxic gas leak occurs in a certain enterprise in the park, it is often difficult to locate where the leak occurred
Because the park is often very large, and the enterprises gathered are of the same or similar type, which brings difficulties to the follow-up work
Once it cannot be organized, the spread of toxic gas will cause fatal hazards t

Embodiment

[0017] The invention provides a method for locating a poisonous gas leakage source based on a wireless sensor network, the steps are:

[0018] Such as figure 1 As shown in , a sensor is respectively arranged on the four corners of a certain unit area that needs to be detected, that is, the first sensor A, the second sensor B, the third sensor C and the fourth sensor D, and the sensing radius of each sensor is the same , the two sensors located on the opposite corner are tangent to the circle formed by the sensor as the center and the sensing radius as the radius, so that the four sensors completely cover the unit area, and the sensor data is transmitted through the wireless network;

[0019] Among them, each sensor has four functions independently: 1. Gas attribute sniffing; 2. Gas concentration analysis; 3. Wind direction detection and 4. Wind speed detection. Through the above deployment method, complete coverage of the unit area can be achieved, and the negative cost broug...

Abstract

The invention provides a poisonous gas leakage source-locating method based on a wireless sensor network. The poisonous gas leakage source-locating method is characterized in that the poisonous gas leakage source-locating method includes the following steps: firstly, a plurality of sensors are arranged in an area to be detected so as to fully cover the area, and the data of the sensors are transmitted via the wireless network; then, when poisonous gas is leaked, parameters are recorded at different states according to the alarm sequence of the sensors, and according to the parameters, the coordinates of a leakage source leaking the poisonous gas are worked out. The method provided by the invention can locate poisonous gas leakage sources, analyzes the spread and motion of a mass of gas respectively in combination with a turbulence model and a Gaussian model in microscopic and macroscopic views, and also introduces a key influencing factor - wind.

Description

technical field [0001] The invention relates to a method for locating poisonous gas leakage sources based on a wireless sensor network, which collects gas information at the initial stage of gas leakage through a sensor array to realize wireless transmission of gas leakage information and real-time positioning of gas leakage points. Background technique [0002] With the continuous development of industry, there are more and more large-scale factories, and the government also prefers to arrange enterprises belonging to a certain type in one area. Relying on this area, build a large and mature society around it to facilitate the employees working in this area and meet their living needs. For areas where chemical production enterprises gather, one of the biggest threats is the possible leakage of toxic gas from a certain enterprise in the park. Once a toxic gas leak occurs in a certain enterprise in the park, it is often difficult to locate where the leak occurred. Because t...
