Integrated online monitoring system for liquid level and flow in drainage pipelines

Abstract

The invention discloses an integrated online monitoring system for drainage pipeline liquid level and flow. The system is composed of a data center and at least one monitoring subsystem. Each monitoring subsystem comprises a monitoring point and a monitoring device installed on the monitoring point. The monitoring devices collect related monitoring data of the monitoring points and send the monitoring data to the data center for processing and real-time dynamic displaying. The integrated online monitoring system for the drainage pipeline liquid level and flow can be applied to liquid level and flow online monitoring, waterlogging or overflowing early warning and alarming, monitoring data public issuing, monitoring data statistic analysis and the like of point locations such as a drainage pipeline, a drainage channel, a drainage inspection well, a drainage opening, a city sunken road, a city underground parking garage and a city receiving water body.

Description

technical field [0001] The invention relates to an integrated on-line monitoring system of liquid level and flow in drainage pipes, which can also be applied to on-line monitoring of liquid level, flow velocity and flow in other partial or full pipes. Background technique [0002] By formulating a reasonable and feasible monitoring plan, on-site monitoring of the liquid level and flow of the drainage network is a necessary condition for scientific management, statistical calculation, simulation evaluation and early warning analysis of the drainage network. The long-term series of online monitoring data of liquid level, flow velocity and flow can support the calibration and verification of relevant parameters of the drainage model, so as to ensure the reliability of the simulation results and improve the credibility of the simulation prediction; Statistical analysis can intuitively find problems such as overload, overflow, siltation, inflow in rainy days, groundwater or river...

AI Technical Summary

Problems solved by technology

[0004] (1) The measurement of the existing flow monitoring equipment is usually 5-15 minutes, and the communication frequency cannot be automatically changed according to the liquid level and flow monitoring data. It can meet the needs of long-term operation monitoring of the drainage system, but it cannot meet the early warning and dynamic monitoring of the drainage pipe network. technical requirements for management;

[0005] (2) The existing equipment is installed under the drainage well as a whole, and the GPRS network is usually used for communication, which leads to high power consumption of the main engine, and the underground communication environment is not good, so the data may not be sent in time due to network signals, and the battery replacement cycle of the main engine is short , and need to open the manhole cover for each maintenance process, which is time-consuming and labor-intensive;

[0006] (3) The functions of existing equipment are mainly based on single-point liquid level and flow monitoring. The built-in clocks of multiple devices cannot be automatically synchronized, and the data collection time cannot be accurately controlled, nor can the flow rate be automatically encrypted when the liquid level or water temperature changes drastically. The frequency of data collection is not conducive to the monitoring of the dynamic change law of the drainage pipe flow and liquid level;

[0007] (4) Existing equipment can only access the data of the equipment through special background software and complex and cumbersome configuration process. The software usually used is mostly stand-alone software, with weak data management and sharing and publishing functions, and usually does not have unified network services. Interface, the data cannot be pushed to the mobile phone for display in time, which is not conducive to the sharing and release of monitoring data and the timely and fast push of alarm information
