Problems solved by technology

[0004] The traditional liquid level monitoring equipment adopts the principles of ultrasound and pressure, which has a large blind area and cannot realize full-scale monitoring. The echo interference caused by the large signal transmission angle causes false alarms, and the unstable sensor causes sometimes no monitoring data.

Embodiment 1

[0040] This embodiment discloses a liquid level monitoring method suitable for deep well liquid level monitoring, comprising the following steps:

[0041] After the liquid level monitoring equipment is powered on, first turn on the absolute pressure sensor to measure the liquid level data. If the two probes of the absolute pressure sensor measure the same value, the liquid level measurement data of the absolute pressure sensor is invalid, and turn on the radar liquid level sensor to measure the liquid level data. measurement; otherwise, the liquid level measurement data of the absolute pressure sensor is valid, and there is no need to turn on the radar liquid level sensor;

[0042] The absolute pressure sensor or radar liquid level sensor sends the collected liquid level measurement data to the main controller, and the main controller processes the collected liquid level measurement data, and wirelessly uploads the liquid level measurement data to the host computer through the ...

Embodiment 2

[0051] Such as Figure 2-7 As shown, this embodiment provides a liquid level monitoring device suitable for deep well liquid level monitoring. The liquid level monitoring device is installed on the side wall of the wellbore at the bottom of the well cover. The liquid level monitoring device includes a main controller 101, an absolute pressure sensor 102 , radar liquid level sensor 103, power management module 104, wireless communication module 105, bluetooth module 106, data storage module 107, main controller 101 and absolute pressure sensor 102, radar liquid level sensor 103, power management module 104, wireless communication module 105, the Bluetooth module 106, and the data storage module 107 are electrically connected.

[0052] The main controller 101 is responsible for controlling peripheral resources to coordinate and orderly work and provide data analysis and processing functions, which are specifically manifested as data collection, analysis and processing, transmiss...

Embodiment 3

[0062] Such as figure 1 As shown, this embodiment provides a liquid level monitoring device suitable for deep well liquid level monitoring. On the basis of the above embodiments, the various circuits of the liquid level monitoring device are also installed and arranged to facilitate the realization of full coverage monitoring of the liquid level without blind areas. Effect. figure 1 The middle marks are: 1. Pavement; 2. Manhole cover; 3. Cover seat; 4. Well shaft; 5. Well seat; 6. Pipeline interface; 7. Base plate.

[0063] The shell selection and design of liquid level monitoring equipment meet the following conditions:

[0064] (1) Selection of support for liquid level monitoring equipment

[0065] The liquid level monitoring equipment bracket is mainly used to install and fix the liquid level monitoring equipment host, sensor, battery pack and connecting cables and other components. It not only provides protection for each component, but also facilitates the on-site insta...

Abstract

The invention discloses a liquid level monitoring method and device suitable for deep well liquid level monitoring, and the method comprises the following steps: starting an absolute pressure sensor to carry out data measurement; if the measurement values of two probes of the absolute pressure sensor are the same, determining that the liquid level measurement data are invalid, and starting a radar liquid level sensor to carry out liquid level measurement; otherwise, determining that the liquid level measurement data is valid, wherein the radar liquid level sensor does not need to be started; enabling the absolute pressure sensor or the radar liquid level sensor to send collected liquid level measurement data to the main controller, and enabling the main controller to process the collected liquid level measurement data and wirelessly upload the liquid level measurement data to the upper computer through the wireless communication module; and enabling the upper computer to correctly receive the liquid level measurement data, then send a response frame to the liquid level monitoring equipment, and carry out data processing. Remote online monitoring of multiple underground liquid level data of the drainage pipeline can be achieved, wiring is not needed, and the monitoring coverage range is wide; through supplementary application of the double absolute pressure sensors, full-scale non-blind area monitoring is achieved.

Description

technical field [0001] The application relates to the technical field of urban drainage system monitoring, in particular to a liquid level monitoring method and equipment suitable for deep well liquid level monitoring. Background technique [0002] With the increase of urban population, the speed of urban construction is far faster than the speed of urban drainage pipe network reconstruction, which makes the urban drainage system face huge challenges, which is also the reason why many cities are flooded in the rainy season. This makes us have to think about how to protect the life and property safety of urban residents while pursuing a big, new and fast city. [0003] The urban drainage and waterlogging prevention system is a complex and interrelated network system, involving multiple departments such as road administration, gardens, and river courses. There are also many causes of urban waterlogging, among which the imperfect early warning and supervision system is one of t...
