京杭大运河崇贤贤园噪音指数数据

实时监测京杭大运河崇贤贤园区段的噪音数据，经过算法加工得到噪音指数数据。通过噪音指数数据，对京杭大运河航运噪音大小进行实时预警，指导京杭大运河航运系统合理安排航运时间和货船数量，保护周边生活的人群免受噪音污染的影响，为京杭大运河的数字化航运体系建设提供有效数据支撑。（1）数据采集：通过在线设备，每分钟实时测量获取京杭大运河东湖姚家埭区段噪音（A，单位：dB）数据；
（2）数据处理：依据监测时间，将噪音数据所处时段分为昼间（6:00-18:00）和夜间（18:00-6:00）。昼间时，噪音指数计算方法：噪音指数=（噪音-70）/70；夜间时，噪音指数计算方法：噪音指数=（噪音-55）/55。
根据我国声环境质量标准（GB3096－2008）中的规定，内河航道昼间噪音不超过55dB，夜间不能超过77dB。噪音数据越接近于1，代表环境越安静。噪音指数监测的预警值为0。当噪音指数数据小于0时，则表示存在噪音污染，应立即采取降低噪音额度必要举措。
（3）数据应用：通过噪音指数数据，对京杭大运河航运噪音大小进行实时预警，指导京杭大运河航运系统合理安排航运时间和货船数量，保护周边生活的人群免受噪音污染的影响，为京杭大运河的数字化航运体系建设提供有效数据支撑。

This dataset focuses on real-time noise monitoring of the Chongxian Xianyuan Park section of the Beijing-Hangzhou Grand Canal, with noise index data generated via algorithmic processing. Based on the noise index data, real-time early warning of shipping noise levels along the Beijing-Hangzhou Grand Canal is conducted, to guide the canal's shipping system in reasonably arranging shipping schedules and cargo ship quantities, protect nearby residents from noise pollution, and provide effective data support for the construction of the Beijing-Hangzhou Grand Canal's digital shipping system.

(1) Data Collection: Noise data (A-weighted, unit: dB) of the Donghu Yaojiadai section of the Beijing-Hangzhou Grand Canal is collected in real-time every minute through online monitoring equipment;
(2) Data Processing: Based on the monitoring timestamp, the time period of noise data is divided into daytime (6:00-18:00) and nighttime (18:00-6:00). For daytime, the noise index calculation formula is: Noise Index = (Noise - 70) / 70; For nighttime, the noise index calculation formula is: Noise Index = (Noise - 55) / 55.
According to the provisions of China's Environmental Acoustic Quality Standard (GB3096-2008), the allowable noise level for inland waterways is no more than 55 dB during daytime and 77 dB during nighttime. The closer the noise data is to 1, the quieter the surrounding environment is. The early warning threshold for noise index monitoring is 0. When the noise index data is less than 0, it indicates that noise pollution has occurred, and necessary measures to reduce noise levels should be taken immediately.
(3) Data Application: Using the noise index data, real-time early warning of the shipping noise level along the Beijing-Hangzhou Grand Canal is conducted, guiding the canal's shipping system to reasonably arrange shipping schedules and cargo ship quantities, protect nearby residents from noise pollution, and provide effective data support for the construction of the Beijing-Hangzhou Grand Canal's digital shipping system.
