摘　　要：在某煤矿实际应用中,为了解决制氮系统中制氮机和增压机工作效率低,受单机控制,无法集中运行的缺点,基于PLC的制氮机远程监控系统,结合Profibus-DP网络和Modbus通信,将多套制氮机进行组建整合并对其进行组合优化和实时监控。通过压力测试和一次控制成功率测试,结果表明:随着并发数的增加,数据通信延时也会增加,并出现一定的丢包数量,但丢包率在可控范围内;测试组较少时控制成功率可达100%,测试数据多、测试组较多时控制成功率也可以保持99%以上。综合表明云端服务器对制氮机远程监控系统的效果良好。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.
