Description

Technical Field

[0001] This invention relates to the field of multi-parameter monitoring technology, and in particular to a data acquisition method and system for water supply and drainage pipe networks. Background Technology

[0002] The field of multi-parameter monitoring technology encompasses technologies that integrate multiple sensor parameters to achieve multi-dimensional state perception of target objects. Its core lies in employing a distributed sensor network architecture, deploying various types of sensors to acquire multiple physical or chemical parameters of the target object, and transmitting the collected raw data to a designated unit via wired or wireless communication, forming a complete monitoring data chain. This field integrates sensing and data transmission technologies, covering multiple application scenarios such as industrial monitoring, environmental monitoring, and water monitoring. It revolves around multi-dimensional data acquisition and transmission that is not limited to a single variable, adapting to the need for comprehensive state understanding of target objects in various scenarios, and falling within the technical scope of measuring two or more variables that are not included in other single subcategories.

[0003] One method for collecting data from water supply and drainage networks refers to specific technical means for collecting relevant data during the operation of water supply and drainage networks. The technical aspects covered include the collection of multiple parameters such as flow rate, pressure, water level, and water quality at key nodes of the water supply and drainage network. Specifically, based on the requirement of measuring two or more variables that are not included in other individual subcategories, flow meters, pressure sensors, water quality sensors, and water level sensors are installed at key nodes such as water source booster stations and zone metering areas of the water supply and drainage network. The parameter data collected by various sensors are transmitted in real time to a designated data receiving unit via wireless communication methods such as NB-IoT and 4G. Simultaneously, manual on-site collection of network-related data not yet obtained through sensing devices can be combined to complete the comprehensive collection of multi-parameter data from the water supply and drainage network.

[0004] Existing technologies focus on deploying sensors to collect and transmit parameters without calibrating and adjusting the acquisition benchmark. Even when parameters deviate, data is still collected based on a fixed benchmark, resulting in data that does not meet actual needs. They also fail to identify and classify environmental interference, leading to mixed interference information in complex environments, increasing processing burden and increasing the risk of failure. Furthermore, the lack of a dynamic filtering mechanism results in the simple collection and transmission of data, with invalid data consuming resources and reducing efficiency. The failure to clearly define acquisition requirements according to node type leads to insufficient accuracy in key parameter acquisition due to a lack of standardized criteria. Finally, the absence of adaptation and verification processes results in insufficient usability and reliability of the collected data, impacting subsequent analysis and decision-making.
