基于气象因素的集中供热系统热负荷预测研究

为了解决直升机旋翼伺服作动器维修保障过程中训练资源有限,拆装难度高,故障率较高且难以确定故障点等难题,在直升机虚拟维修训练系统(VMTS, Virtual Maintenance Training System)的基础上,提出了应用虚拟仪器检测,确定故障点的直升机故障诊断可视化设计方法。分析了故障诊断过程中仪器、工具、环境等对故障诊断的影响,实现了动态的建立仿真模型和数据处理。通过虚拟仪器和推理机的功能配合,解决了直升机维护中复杂多变的故障诊断难题,形成一个逻辑推理能力强的故障诊断系统。最后以直升机旋翼伺服作动器故障诊断为例,验证该方法的可行性。

Research of District Heating System Heat Load Prediction Based on Weather Factors

In order to solve a helicopter rotor servo actuator maintenance support during limited training resources, disassembly difficult, high failure rate and it is difficult to determine the point of failure and other problems, the helicopter virtual maintenance training system (VMTS, Virtual Maintenance Training System) on the basis of on the proposed application of virtual instrument detection, to determine the point of fault diagnosis helicopter visual design. Analysis of the fault diagnostic process instruments, tools, environmental impact on fault diagnosis to achieve a dynamic simulation model and data processing. Through the virtual instrument and reasoning machine functions with to solve the helicopter maintenance, troubleshooting complex problems into a logical reasoning ability of fault diagnosis system. Finally, a helicopter rotor servo actuator fault diagnosis, for example, to verify the feasibility of the method.
