Abstract

The invention discloses a hazardous chemical gas monitoring method based on an NB-IOT technology. The method comprises the following steps: collecting concentration data, pressure data and image data of hazardous chemical gas; establishing a data transceiving model of the NB-IoT equipment; establishing a position equation of the hazardous chemical gas pipeline by utilizing the longitude and the latitude; establishing a model by using a whale optimization algorithm to predict a dangerous chemical gas leakage source and search the leakage source; establishing a concentration change establishment model; establishing a hazardous chemical gas pressure change model by using a thermodynamic theory of gas; carrying out resolution adjustment and decoding on the dangerous chemical gas image; establishing a hazardous chemical gas leakage similarity function, and positioning a leakage source; and calculating a signal receiving power difference value of the NB-IOT equipment, and transmitting the data to the model to complete monitoring of the hazardous chemical gas. The method is easy to understand and high in operability, the leakage problem of the hazardous chemical gas in pipeline transmission is effectively monitored, wide coverage is achieved, and the safety of the hazardous chemical gas in transmission is guaranteed.

Description

technical field [0001] The invention relates to the field of gas monitoring and algorithms, in particular to a hazardous chemical gas monitoring method based on NB-IOT technology. Background technique [0002] At present, the hazardous chemical gas monitoring system uses a single sensor to collect and monitor the hazardous chemical gas one-to-one, and the detection of the gas by a single sensor is not accurate enough; secondly, in the traditional hazardous chemical gas monitoring system, the hazardous chemical gas monitor is only responsible for detection. Gas data monitoring, the sampling instrument only samples the gas to be detected, the detection of hazardous gas and sampling are uncertain, and it is impossible to accurately detect the hazardous gas to be detected, so as to facilitate further adoption of the national standard three-bag method in the later stage. testing as a basis for law enforcement. Secondly, the traditional hazardous gas monitoring methods are not ac...
