In view of the actual situation of the current traditional natural gas leakage monitoring, the current process of natural gas leakage monitoring methods is cumbersome. Traditional sensor deployment methods have problems such as deployment blind spots and low utilization of sensor nodes. In this paper, combined with the gas diffusion law and leakage weak links, the weak links of pipeline leakage are judged through simulation. On the basis of the weak link analysis, the gas diffusion law of gas pipeline leakage in dangerous natural gas plants is obtained by further using Fluent simulation. The law of gas diffusion is analyzed, and the leakage gas accumulation area on the top of the factory building is obtained. Through the qualitative analysis of the leakage accumulation area, based on the virtual force algorithm, the resource utilization rate is improved under the premise of ensuring the space coverage, and the optimal deployment strategy of the sensor is generated. Through simulation and comparison of experimental results, it is concluded that the sensor deployment method based on the law of gas diffusion and considering weak links can effectively improve the utilization of sensor nodes and reduce the range of monitoring blind spots
