【摘要】：从煤矿安全监控系统升级改造方案中对数据分析和伪数据识别的需求入手,以瓦斯数据为例,分析了3种最常见的伪数据类型及其产生原因。针对传感器标校产生的伪数据,提出应增加专门针对伪数据识别的标校实验;针对电磁干扰产生的伪数据,提出通过预先在传感器程序中埋入误码来模拟干扰点瓦斯浓度值的方法;针对传输或者设备故障产生的伪数据,提出随机制造传感器或者传输线路故障,观察数据处理结果的方法。对某厂家的安全监控系统进行模拟检验,验证了所提方法的有效性和可行性。
[Abstract]:Based on the requirement of data analysis and pseudo-data recognition in the upgrading scheme of coal mine safety monitoring system, three kinds of most common pseudo-data types and their causes are analyzed, taking gas data as an example. Aiming at the pseudo-data generated by sensor calibration, the calibration experiment for the identification of pseudo-data should be added. Aiming at the pseudo-data generated by electromagnetic interference, a method of simulating the gas concentration of interference points by embedding error codes in the sensor program is put forward. According to the pseudo data generated by transmission or equipment fault, the method of randomly manufacturing sensor or transmission line fault and observing the result of data processing is put forward. The effectiveness and feasibility of the proposed method are verified by simulating the safety monitoring system of a factory.
