摘要
针对地铁车站空调监控系统实时性的要求,提出了基于ZigBee技术的地铁车站空调运行监控系统,给出了监控系统的结构。使用CC2430组成BAS系统的环境数据采集与传输、设备运行控制的控制器,给出了传感器和控制节点电路。为消除检测数据中粗大误差的影响,采用多项式最小二乘曲线拟合算法,对粗差点的数据进行补值处理,设计了数据处理流程进行检测数据的粗差处理。实际应用表明,该系统能够消除各类检测数据中的粗大误差,保证BAS监控系统的可靠性。
Aiming at the timely requirement of real-time of the subway integrated monitoring system, the monitoring system of the subway integrated monitoring system System which is based on ZigBee technology is put forward. pictured its System network structure. and the CC2430 chip which is based on ZigBee technology is applied to system environmental data collection and transmission, air conditioning equipment operation control and so on. Then the article devised one circuit schematic for performance data collecting, control node of Equipment and monitoring network main node and so on. to eliminate the impact of gross error detection data using polynomial least squares curve fitting algorithm in order to pull Ida criteria for detecting data noise error variance statistics basis using dynamic threshold discriminated the gross error processing gross errors in the data points and removed, then the statistical properties of crude handicap data complement value processing, the design of the data processing flow detection data. The practical application shows that the method can eliminate the gross errors in the various testing data, and to ensure the reliability of the monitoring system.
