Modelling of hardware and software system for monitoring the rate of change in fluid or gas pressure in a pipeline

Relevance. Modern pipeline systems play a key role in transportation of liquids and gases. Such systems are becoming increasingly complex and serious problems arise in terms of pressure control and accident prevention to ensure their reliability. This highlights the need to develop effective methods for monitoring and controlling pressure in pipelines. Aim. To develop and model the hardware and software tool for monitoring the rate of change in fluid or gas pressure in a pipeline. Methods. Mathematical modelling and statistical data processing. Results and conclusions. The pressure in the pipeline system changes depending on the state of the valves and the time of their switching. Graphical analysis of the data confirms that the rate of pressure changes increases significantly when the valves are switched, which can lead to sharp pressure fluctuations. During the modelling, quantitative characteristics of these changes were obtained. The use of pressure thresholds allows for effective control of system stability and prevention of emergency situations. The developed digital pressure monitoring device can be implemented in various industries, including the oil and gas and chemical industries, which will significantly increase the reliability and safety of pipeline systems. In the future, it is necessary to investigate the possibilities of integrating the described device with intelligent control algorithms capable of not only taking into account the current state, but also predicting pressure changes under the influence of external factors. The influence of parameters such as temperature and composition of transported substances on the pressure dynamics in pipelines should also be taken into account.
