| Mine air compressors are one of the indispensable equipment of mining enterprises.It is mainly used to provide high-pressure gas for the use of pneumatic tools for mining workers,such as wind picks,pneumatic drill and so on.However,the construction site of the mine on the demand for high-pressure gas is not fixed,the mine line of air compressor control system technology is relatively backward,the corresponding monitoring equipment is not perfect,so the mine air compressor unit is often in the process of running Resulting in failure,which also directly or indirectly led to the production often can not be normal,because the normal use of gas production is not effective protection.At the same time,low efficiency,energy consumption,control mode behind,low degree of automation has long been the existence of long-term air compressor units.In particular,the large air compressor used in the mine,24 hours of continuous work is almost normal,but the load or light load operation of the proportion is quite large.So on the one hand to change the air compressor control mode,on the other hand to improve the efficiency of air compressor and air compressor at the same time reduce the overall energy consumption.In this paper,the basic principle and method of intelligent monitoring and monitoring system design of air compressor unit are analyzed in detail in this paper.The monitoring and monitoring part of the system is composed of Rsview configuration software and GE PLC program design software to achieve.The monitoring part is composed of multiple configuration interfaces.Through the system,the staff can easily grasp the whole system of the air compressor and the working status of each part.The system can also adjust the corresponding parameters to optimize the output and improve Air compressor control system energy efficiency,reduce the system operating failure rate.At the same time,the system upgrade project successfully in the traditional monitoring and monitoring system to add a fuzzy control strategy,the general principle is as follows:First,according to the total duct pressure deviation rate of change introduced PID tuning of the three coefficients(P?Ti?Td),And then through these three coefficients,pressure deviation and rate of change introduced control increment,then we will push the incremental into the intelligent optimization strategy,the system can be combined with the inverter output frequency and control increment,get empty Presses need to run the number and manner,on this basis,and then refer to several other data,you can carry out the calculation of fuzzy control,and finally get the air compressor start and stop the specific coding machine and the system needs to adjust the inverter changes And then use the system to calculate the data automatically control the system,the whole system through this way to complete the air compressor on the effective intelligent round of operation control,and according to the construction site of the air flow in a timely manner on the supply of wind Pipeline pressure is effectively adjusted to minimize energy consumption and loss of air compressors.Since the operation of the air compressor monitoring and control system has been stable,the pressure of the total supply air pipe is basically stable in the small range,and the operation time of each air compressor is relatively uniform.The system can control the pressure of each air compressor The specific situation of the machine in a timely manner to adjust the operating state,air compressor running conditions greatly reduced,air compressor from the frequency to frequency control after the start of a smooth,the impact on the power grid significantly reduced,greatly improving the mine gas System stability,reduce energy consumption,to achieve a safe production,improve production efficiency,for the Jiaojia Gold Mine has brought a very good economic benefits. |
