Abstract

The application discloses an intelligent liquid level monitoring method and system for an urban underground utility pipe gallery. The method includes the following steps: adopting an optical detectiondevice to detect a liquid level value of a liquid level sampling point that is expressed by optical signal data in a utility pipe gallery in real time; after the liquid level value corresponding to the optical signal data reaches an early warning value, not starting a drainage system, but continuing to judge whether the liquid level value is maintained within an early warning range during a T time period from the current moment when the early warning value is reached; only when determining that the liquid level value is maintained within the early warning range during the T time period, determining that the liquid level reaches the warning liquid level; and at this time, generating a control instruction to control the drainage system in the utility pipe gallery to initiate a drainage process. Therefore, according to the method and the system provided by the embodiment, the liquid level value is continuously judged after the liquid level value reaches the early warning value, the phenomenon that the liquid level exceeds the standard can be determined only when the liquid level value is maintained within the early warning range during the T time period, so that more accurate liquidlevel monitoring can be realized, the start-up and shutdown of the drainage system can be accurately controlled, and the waste of electric energy can be reduced since the number of start-up and shutdown times of the drainage system is reduced.

Description

technical field

[0001] The present application relates to the technical field of integrated utility tunnels, in particular to an intelligent liquid level monitoring method and system for urban underground integrated utility tunnels. Background technique

[0002] The urban underground comprehensive pipe gallery (hereinafter referred to as "comprehensive pipe gallery") is a tunnel space built underground in the city. It integrates electricity, communications, gas, heating, water supply and drainage, and various engineering pipelines into one structure and ancillary facilities. According to the different properties of the engineering pipelines, the comprehensive pipeline gallery is divided into different compartments, each compartment is isolated from each other, and a passage for personnel and vehicles is formed in each compartment along the length of the engineering pipeline. like figure 1 The vertical cross-sectional view of the urban underground comprehensive pipe gallery ...
