基于IDL的某地下工程通风系统设计与实现

为解决某地下工程通风系统信息化条件不高，缺乏相应预测功能，通风设备的风量参数不能实现在线监测等薄弱环节。通过了基于三维可视化场景设计开发了一套地下工程空调通风控制在线监测系统（以下简称通风监测系统）来解决上述问题。系统采用了IDL和C#混合编程技术，将传感器实时采集的数据存入数据库，然后通过调用灰色度算法生成性能曲线和预测结果。论述了三维场景生成与显示、数据库查询优化等关键技术。结果表明了通风监测系统的可行性和实用性。极大地提高了地下工程管理效率和监测水平。

Design and implementation of underground ventilation system based on IDL

In order to solve a ventilation system underground engineering information conditions,with the lack of corresponding prediction function,ventilation air flow parameters can not be achieved on-line monitoring and other unsubstantial links.Through the scene based on three-dimensional visualization to design and develop a monitoring system for underground engineering air condition and ventilation control line(hereinafter referred to as ventilation monitoring system) to solve the above problems.System uses a mixture programming technology of IDL and C#.real-time acquisition of sensor data into the database,then generate performance curves and forecast results through transferring gray-degree algorithm.Discusses the three-dimensional scene generate and display,database query optimization and other key technologies.The results show the feasibility and practicality of ventilation monitoring system.Greatly improve the efficiency of underground project management and the level of monitoring.
