计量泵群远程监控方案及其数据服务器设计

Remote monitoring scheme of metering pump group and design of data server

计量泵被广泛应用于各种流体工业中,国内外对此的研究多集中于工艺结构改良和机电一体化系统设计,而鲜有多泵、泵群远程监控和协调调度方面的研究。针对实际工业中计量泵通常需要协同工作的现状,分析和改进了计量泵网络化监控方案,使之满足对大规模计量泵群的远程监控需求;设计了一套基于Java的专用数据服务器软件,实现了监控系统的数据交换和数据维护;针对数据量大引起的系统性能下降问题,结合环形缓存机制提出了一种环形对象池技术的设计和实现方案;最后模拟不同的网络负载条件测试了数据延时时间。研究结果表明,服务器能够保证数据的实时性,能够应用于大规模计量泵群的远程监控中。

Metering pumps are widely used in fluids industry. Current researches often focus more on international structure improvement and design of automation systems, while lacking on remote monitoring and coordination of pump groups. Aiming that the metering pumps typically cooperate to work in industry,an improved plan of metering pumps networking monitor solution and appropriate commniucation method was presented to meet the needs of large-scale monitoring. A Java based data server was designed to manage data in monitoring system. To solve the problem of system performance degradation,a scheme of ring object pool was put fowward,based on ring cache mechanism. Finally, different conditions and testing network delay time were simulated. Results indicate that the server can ensure data real-time and reliable, and can be used in large-scale metering industrial monitoring.
