基于多传感器技术的城市供水水质预测

Prediction of urban water supply quality based on multi-sensor technology

城市供水系统对供水的浑浊度,pH值等水质指标进行监测,当超出事先给定的极限值时,进行应急处理,保证供水安全,由于供水管道中的水体具有随机波动性,若使用单一的极限值监测方法,很难及时发现问题.通过采用多传感器技术,应用多变量状态分析原理,对水质的变化做出趋势预测与分析,并在确定趋势类型后,针对每一种趋势类型设定相应的措施.研究结果表明,采用该方法能够对实际过程进行有效的预测.

The quality index such as pH value, turbidity etc, are monitored by urban water supply system. When the quality index surpasses the limitation, the response system will handle the treatment effectively to against accident and ensure the water safety. While, the water in pipelines has random fluctuation, it is diffi cult to find the problem with limit value monitoring. By applying the method of multivariate data analysis and based on multi - sensor technology, the change trends of water quality can be forecasted. Accroding to the trends type, the corresponding measures are designed. The results indicate that the actual process can be forecasted effectively.
