Design and Implementation of Remote Monitoring System for Coal Mine Nitrogen Generator
In the practical application of a coal mine,in order to solve the shortcomings of the nitrogen generator and booster in the nitrogen production system,which have low efficiency and are controlled by a single machine and cannot be operated centrally,a PLC-based remote monitoring system of the nitrogen generator is designed and implemented.The remote monitoring system of nitrogen generator based on PLC,combined with Profibus-DP network and Modbus communication,sets up and integrates several sets of nitrogen generators and carries out combination optimisation and real-time monitoring of them.Through the pressure test and one control success rate test,the results show that:with the increase of concurrency,the data communication delay will increase,and there is a certain number of packet loss,but the packet loss rate is within the controllable range;when the test group is smaller,the control success rate can reach 100％,and when the test data is large,and the test group is larger,the control success rate can be maintained at more than 99％.The synthesis shows that the cloud server is effective for remote monitoring system of nitrogen generator.
