Intelligent on-line liquid level monitoring and early warning system

Abstract

The invention discloses an intelligent on-line liquid level monitoring and early warning system. The intelligent on-line liquid level monitoring and early warning system is composed of a data center and at least one liquid level monitoring and early warning subsystem, and is characterized in that the liquid level monitoring and early warning subsystem comprises a liquid level monitoring point, a liquid level monitoring host and a monitoring repeater; the liquid level monitoring host is used for carrying out continuous monitoring on the liquid level monitoring point, generating monitoring data and transmitting the monitoring data to the monitoring repeater according to a changeable transmission time interval, and the monitoring repeater is used for receiving the monitoring data and transmitting the monitoring data to the data center according to the changeable transmission time interval; the data center is used for processing the received monitoring data to obtain status data and various curves of the liquid level monitoring point and displaying and releasing the status data of the liquid level monitoring point in real time. By means of the intelligent on-line liquid level monitoring and early warning system, on-line liquid level monitoring, short-message warning, waterlogging early warning, short-time forecasting, monitoring data public release and the like can be carried out on points such as a drainage pipeline, a drainage channel, a drainage inspection well, a drainage exit, an urban sunken road, an urban underground parking garage and urban receiving water.

Description

technical field [0001] The invention relates to a liquid level monitoring and early warning system used in municipal and water conservancy fields such as rainwater, sewage, reclaimed water, rivers, lakes, roads, etc., in particular to an intelligent online liquid level monitoring and early warning system. Background technique [0002] In recent years, waterlogging events have occurred in many cities in my country during the rainy season every year, showing the characteristics of a wide range of occurrences, a large depth of water accumulation, and a long time of water accumulation. The occurrence of waterlogging incidents not only brings inconvenience to people traveling in rainy days, but also leads to huge losses of personal and public property, and even threatens the safety of people's lives, which has aroused widespread concern from all aspects of society. However, there are many reasons for urban waterlogging events, such as frequent extreme weather phenomena, the incre...

Problems solved by technology

[0004] (1) The frequency of measurement and data communication of existing equipment is usually 5-15 minutes, which can meet the needs of long-term operation monitoring of the drainage system, but cannot meet the technical requirements of early warning and alarm of waterlogging in the drainage pipe network;

[0005] (2) The existing equipment is installed in the drainage well as a whole, and the GPRS network is usually used for communication, resulting in high power consumption of the main engine, and the underground communication effect is not good, resulting in data that cannot 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 function of existing equipment is mainly based on single-point liquid level monitoring. The measurement time of multiple equipment cannot be automatically synchronized, and the unified collection time of data cannot be accurately controlled. The data synchronization and comparability are not strong, which is not conducive to the integration of multiple equipment. data comparison and statistical analysis;

[0007] (4) Existing equipment usually has measurement blind spots, which cannot effectively monitor surface water accumulation, and cannot send data and alarm signals in time after the equipment is submerged in water, which affects the dynamic monitoring and early warning and forecasting of waterlogging events;

[0008] (5) The function of the data center of the existing equipment is weak, and it needs cumbersome configuration to access the equipment signal, and there is no integrated interface for social platforms such as WeChat and Weibo, which is not conducive to the public release of monitoring data and alarm information. Fast and effective push
