Example Embodiment

[0039]Example 1

[0040]This example discloses a liquid level monitoring method suitable for deep well level monitoring, including the steps:

[0041]After the liquid level monitoring device is powered on, the liquid level data measurement is first turned on. If the two probe measurements of the inspiring sensor are the same, the liquid level measurement data of the inspiring sensor is invalid, and the radar level sensor is turned on. Measurement; otherwise, the pressure sensor level measurement data is valid without the need to turn on the radar liquid level sensor;

[0042]An inspiration sensor or radar level sensor sends the collected level measurement data to the main controller, the main controller processes the collected level measurement data, and the liquid level measurement data is wirelessly uploaded to the host computer via the wireless communication module;

[0043]The upper computer correctly receives the level measurement data to send a response frame to the liquid level monitorin...

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...
