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.
Abstract
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.
