Research And Application Of Intelligent Technology For Mine Heating

With the rapid development of the economy,the demand for heating industrial buildings continues to increase,and the scale also expands.The current level of operation and management is not high,and the energy utilization rate is low,resulting in uneven heating and cooling in the actual heating network,resulting in energy waste.How to realize real-time online monitoring of heating operation can achieve the effect of unattended operation and on-demand heating,and improve the means and methods of fault diagnosis of heating systems and facilities,to achieve the effect of energy saving and emission reduction under the premise of ensuring heating quality.Based on the heating system renovation project of Longshou mine of Jinchuan group company,this thesis applies technologies such as time-division temperature control,climate compensation heating control tec hnology,pipe network water balance control technology,and 5G communication to the local heating system of Longshou mine,and designs an intelligent heating system and energy consumption monitoring and dispatching platform.Firstly,in view of the problems of large inertia,large delay,and nonlinearity in the control system of the heat exchange station,an improved locust optimization algorithm is proposed for the implicit generalized predictive control strategy,which has a good control effect on the hea t exchange station system.The climate compensator enables automatic climate compensation for changes in outside temperature.Under the premise of ensuring the quality of heating,the purpose of saving energy is achieved.By analyzing the work of the build ing site controller,the principle is to install the building time-sharing temperature controller and electric three-way regulating valve at the entrance of the building heat pipe network,analyze the energy-saving and time-sharing performance of the building time-sharing temperature controller,and apply the method of combining neural network and PID control algorithm to control the system.Secondly,an intelligent monitoring platform is established through the SCADA system to achieve grid monitoring and management of the heat exchange station.The unattended heat exchange station monitoring system can collect the main information and key data of the heating network of the whole mine.Through centralized monitoring,real-time data update,remote operation,and other functions,the unattended and fully automatic control of the heat exchange station is realized.It realizes more scientific,efficient,and standardized management of the entire thermal system improves the efficiency of the heat exchange station system,saves the cost of the heating company,produces huge economic benefits,and reduces environmental pollution.Finally,the operation shows that the first heating season of the pilot transformation and operation of the heating system of the mine has ended.According to the current monitoring data,the initial purpose of energy saving and consumption reduction has been achieved,and real-time feedback on the heating effect has been realized,which is a good guarantee for heating.The quality meets the differentiated use requirements of each energy-consuming unit.At the same time,the level of existing heating management has been improved,and the effects of distributed regulation,centralized management,real-time monitoring,and fault warning have been achieved,making the entire heating management process transparent,efficient,and intelligent.
