Detailed Description
Referring to fig. 1, a subway station has a step at an entrance, a camera 1 is installed at the entrance, if there is water accumulation, the water accumulation is accumulated outside the step at the entrance of the subway, at this time, the camera 1 can determine the water accumulation condition at the entrance of the subway through video analysis (for example, through image recognition of step lines, etc., belonging to the prior art, the current deep learning pattern recognition algorithm can be implemented, for example, "WaterSegmentationwithDeepLearningModelsforFlood DetectionandMonitoring", mirkoZaffaroni, etc., procedingsofthe 17th ISCRAMConference-Blacksburg, VA, usamy 2020). In a subway station, for example in a platform area or in a hall area, a scene ponding monitoring camera 2 is arranged for monitoring ponding conditions in the subway station. In practice, there are a plurality of subway entrances, and thus a plurality of cameras 1 and a plurality of scene water monitoring cameras 2 in a subway station are used for monitoring different areas in the subway station. According to the working mode, the camera 1 at the entrance of the subway station can be divided into a patrol camera and a monitoring camera, the risk early warning system processes the data of the patrol camera at regular time, and the data of the monitoring camera is processed according to the requirement, so that the processing load of the system is reduced.
Referring to fig. 1-3, the ponding backward flow subway station risk early warning system comprises a patrol camera, a monitoring camera, a scene ponding monitoring camera, a weather and flood control information collection module and a data analysis early warning module; a patrol camera or a monitoring camera is arranged at the entrance of the subway station and used for monitoring the ponding condition at the entrance of the subway station; a scene monitoring camera is arranged in the subway station and used for monitoring the ponding condition in the subway station; the weather and flood control information collection module is used for obtaining weather information and flood control data of subway stations; the data analysis early warning module is connected with the inspection camera, the monitoring camera, the scene ponding monitoring camera and the weather and flood control information collecting module, and judges ponding conditions according to video data; the working modes of the risk early warning system comprise a primary monitoring mode, a secondary monitoring mode, an early warning mode and an alarm mode.
Under the general condition, the system works in a primary monitoring mode, and the data analysis early warning module regularly analyzes video data of the inspection camera and the scene ponding monitoring camera; when ponding exists in the video data display station of the monitoring camera according to the scene ponding, the situation that the risk of ponding exists is indicated, for example, ponding backflow occurs at a subway entrance where the monitoring camera is located, therefore, the system starts video data analysis of the monitoring camera, and the risk early warning system enters a secondary monitoring mode. At the moment, the monitoring camera is in the same position as the inspection camera, namely, the video data of the monitoring camera can be included for analysis, and the ponding condition at the subway entrance is judged.
In the primary monitoring mode or the secondary monitoring mode, when the accumulated water at the entrance of at least one subway submerges the steps, the risk of accumulated water backflow in the subway station is indicated, and the risk early warning system is switched into the warning mode; when the ponding at all subway inlets does not submerge the steps, but at least one subway inlet has ponding, the risk of potential ponding backflow in the subway station is indicated, and the risk early warning system is switched into an early warning mode.
In the early warning mode, accumulated water exists at the steps of the subway entrance, but the steps are not submerged, but the steps are submerged in future time along with the deepening of the accumulated water, the weather change and the like, so that backflow occurs. Therefore, weather and flood control information are required to be collected for pre-judgment, and weather data comprise rainfall forecast information, weather forecast information and weather early warning release information; flood control data comprise the drainage capacity in the subway station, the opening proportion of the drainage pump, the water level of the drainage well in the station and the like. According to the rainfall change in a future period and the drainage capacity of the subway station, whether the water backflow occurs in a certain period can be judged, and if the water backflow risk is judged, the system enters an alarm mode; if not, monitoring is still performed in the early warning mode until the triggering condition of the early warning mode is not met.
In the same way, the second-level monitoring mode returns to the first-level monitoring mode to execute the normalized monitoring after the triggering condition is not satisfied.
The alarm mode comprises informing subway management staff through mails, telephones and short messages.
Referring to fig. 4, the risk early warning method for the ponding backward flowing subway platform comprises the following steps:
s1: analyzing a scheduled subway station entrance and a ponding state in the subway station by using the timing video;
s2: judging whether water is accumulated in the subway station and at the entrance of the preset subway station, and if water is accumulated in the subway station, executing a step S3; if water is accumulated at the inlet of at least one preset subway station, executing the step S4;
s3: collecting video data of all subway station entrances;
s31: judging whether water is accumulated at the inlet of at least one subway station, if so, executing the step S32, otherwise, returning to the step S3;
s32: judging whether the accumulated water floods the entrance step of the subway station, if so, executing the step S6, and if not, executing the step S5;
s4: judging whether the ponding is flooded with the predetermined subway station entrance steps without ponding, if so, executing the step, otherwise, executing the step S5;
s5: collecting meteorological and flood control data, judging whether the risk of water accumulation and backward flowing of the subway station exists, and if yes, executing a step S6;
s6: and sending out alarm information.
In step S2, it is determined whether there is water accumulation in the subway station, and whether there is water accumulation in the entrance of the subway station is determined simultaneously, and there is no obvious sequence, which is only for illustration, and whether there is water accumulation in the subway station is performed in advance.
In the method, the predetermined subway station entrance is usually a subway station entrance in a patrol state, namely, video information of the subway station entrance is always collected; also, the subway entrance may collect video information only when water accumulation occurs in the subway station, and "all subway station entrances" refer to predetermined subway station entrances and non-predetermined subway station entrances.
According to the invention, the cameras at the subway entrance are divided into two types, namely inspection and monitoring, the inspection cameras are subjected to normalization processing, and the monitoring cameras are processed according to the needs, so that system resources are saved. And the video analysis technology is adopted to judge the ponding condition at the subway entrance, so that the risk of ponding flowing backward to the subway platform is accurately judged. Meteorological conditions and drainage conditions in subway stations are comprehensively considered, accurate and timely alarm is achieved, and therefore accuracy of risk early warning and air defense is improved.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
