The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1-4, the river flood control early warning system based on computer vision recognition disclosed by the invention comprises a plurality of water level early warning posts 10, a calling module 11, a main control desk 12, a display screen 13 and a plurality of alarms 14.
The plurality of water level early warning posts 10 are arranged on the river bank of the village at intervals along the river direction, and it is understood that the village has a plurality of villages, and each village corresponds to one water level early warning post 10.
In this embodiment, the water level early warning post 10 includes a post main body 100 in a strip shape and a plurality of marking discs disposed at intervals along the length direction of the post main body 100, where the color of each marking disc is different, i.e. the marking disc of each color corresponds to one early warning level.
Preferably, the plurality of identification disks includes a first color disk 101 that is liftable and lowerable disposed in a first position of the marker post body 100, a second color disk 102 that is liftable and lowerable disposed in a second position of the marker post body 100 and above the first color disk 101, and a third color disk 103 that is liftable and lowerable disposed in a third position of the marker post body 100 and above the second color disk 102.

Preferably, the controller controls the buzzer 105 to generate a first warning level signal when it is detected that the water level of the river reaches the first color disc 101, controls the buzzer 105 to generate a second warning level signal when it is detected that the water level of the river reaches the second color disc 102, and controls the buzzer 105 to generate a third warning signal when it is detected that the water level of the river reaches the third color disc 103.
Further, when the detected time is night time, the controller controls the LED lamp to flash and lighten so as to prevent collision.
The adjusting module 11 is used for adjusting the camera 20 closest to the water level pre-warning marker post 10 and controlling the camera 20 closest to the water level pre-warning marker post 10 to shoot the water level pre-warning marker post 10 so as to obtain a water level picture, wherein a plurality of cameras 20 are arranged on the river bank along the river direction at intervals.
It should be understood that under normal conditions, the cameras 20 are installed on the road of the river levee, and these cameras 20 are used for photographing the condition on the road under normal conditions, but the river flood control early warning system based on computer vision recognition disclosed in the invention does not need to additionally provide cameras, and directly uses the calling module 11 to call the cameras 20 on the road to photograph the water level early warning marker post 10, so that a lot of operation cost can be saved.
In the present embodiment, the retrieving module 11 includes a pre-determining unit 111, a data acquiring unit 112, a calculating unit 113, a control unit 114 and an uploading unit 115.
The pre-judging unit 111 is used for detecting whether the current weather is rainy days. It should be understood that when the river is not raining normally, the water level of the river is not changed, and only when the river is raining, the water level change is generated, so that whether the current weather is raining needs to be judged in advance, and only when the current weather is raining, the operation of calling the camera closest to the water level early-warning marker post 10 can be started by the calling module 11, so that the operation and maintenance cost can be reduced, and the intelligent degree is high.
The data acquisition unit 112 is configured to acquire a post coordinate value of the water level early-warning post 10 and acquire a plurality of camera coordinate values of a plurality of cameras provided on the river levee when the pre-determination unit 111 determines that the current weather is rainy and the rainy time exceeds a preset time. It should be appreciated that the river water level will not change too much during the period of time immediately preceding rain, and that the post coordinate values of the water level warning post 10 and the camera coordinate values of the cameras will be obtained only when the period of rain exceeds a predetermined period of time (e.g., more than 2 hours).
Further, in some embodiments, when the data obtaining unit 112 is configured to determine that the current weather is rainy, the rainy water exceeds the preset water amount, and the rainy time exceeds the preset time by the pre-determining unit 111, the post coordinate values of the water level pre-warning post 10 and the camera coordinate values of the cameras set on the river levee within the preset distance range of the water level pre-warning post 10 are obtained, where the preset distance range is a value set by the user, and the specific requirement is determined according to the actual situation.
The calculating unit 113 is used for calculating the camera coordinate values of the cameras which are away from the nearest water level early warning marker post 10 through the marker post coordinate values and the plurality of camera coordinate values.
Further, the calculating unit 113 is configured to calculate, through the coordinate values of the post and the coordinate values of the plurality of cameras, the coordinate value of the camera that is located at the distance from the nearest water level pre-warning post 10, and no shielding object exists between the camera that is located at the distance from the nearest water level pre-warning post 10 and the water level pre-warning post 10.
The control unit 114 is configured to control the camera that is closest to the water level pre-warning post 10 to rotate to align with the water level pre-warning post 10, and focus the camera so that the water level pre-warning post 10 can be clearly photographed, and photograph the water level pre-warning post 10 after determining that the camera is aligned with the water level pre-warning post 10 and determining that the focal length of the camera is adjusted, so as to obtain a water level picture. It should be appreciated that the control unit 114 will control the rotation of the camera that is closest to the water level pre-warning post 10 so that the camera can be aimed at the water level pre-warning post 10, while further focusing the camera after determining that the camera is aimed at the water level pre-warning post 10 so that the water level pre-warning post 10 can be clearly photographed.
The uploading unit 115 is used for uploading the photographed water level picture. Specifically, the uploading unit 115 uploads the photographed water level picture in a 4G or 5G manner.
It should be noted that, in some embodiments, the control unit 114 further controls the camera of the nearest water level pre-warning post 10 to rotate again when the pre-determining unit 111 determines that the current weather is not rainy, so that the camera of the nearest water level pre-warning post 10 normally shoots the road on the river dike.
The main control console 12 is used for acquiring the water level picture transmitted by the calling module 11, resolving which identification disc in the water level early warning marker post 10 the water level of the river is in from the water level picture, and matching the corresponding early warning grade according to the resolved identification disc. That is, the pre-warning level corresponding to each identification disc is different, and the corresponding pre-warning level is triggered by which identification disc the water level of the river is located.
In the present embodiment, the main control station 12 includes a receiving unit 121, an analyzing unit 122, and a determining unit 123.
The receiving unit 121 is configured to obtain the water level picture delivered by the uploading unit 115.
The parsing unit 122 is used for parsing the water level of the river and the color of the marking disc reached by the water level from the water level picture.
Specifically, the analyzing unit 122 takes a large-area horizontal plane set in the horizontal direction in the water level picture as the water level plane of the water level of the river, takes a long cylindrical rod set in the vertical direction in the water level picture as the marker post main body 100, takes a circular object which is set on the marker post main body 100 and is circular and is positioned above the water level plane in the water level picture as the marker disc, and directly recognizes the color of the circular object as the color of the marker disc.
It will be appreciated that the surface of a river is relatively planar over a large area (the flow fluctuations may be considered planar) and therefore a large area of water level may be taken directly as the water level. Further, the analyzing unit 122 directly identifies the water level pre-warning post 100 from the water level picture through contour comparison, that is, pre-stores the standard contour of the water level pre-warning post 10, then uses the object with the contour and the standard contour in the water level picture as the water level pre-warning post 10, analyzes the object with the circular shape from the water level pre-warning post 10 as the identification disc, and finally identifies the color of the identification disc located on the water level.
The determining unit 123 is configured to determine a first warning level when it is determined that the water level reaches the first color disc 101, determine a second warning level when it is determined that the water level reaches the second color disc 102, and determine a third warning level when it is determined that the water level reaches the third color disc 103.
The display screen 13 is used for displaying the early warning level, the village name corresponding to the early warning level, the village address corresponding to the village name and the water level value corresponding to the early warning level.
The plurality of alarms 14 are arranged on the river bank of the village at intervals along the river direction and are used for generating corresponding early warning prompts according to the early warning level, wherein each alarm corresponds to each water level early warning marker post 10 one by one, namely when the water level of a certain water level early warning marker post 10 triggers early warning, the alarm 14 corresponding to the water level early warning marker post 10 generates corresponding early warning, and thus villagers in the corresponding village can be reminded through the alarm 14 to take corresponding measures.
In this embodiment, when the alarm 14 determines that the water level warning of the water level warning post 10 reaches the first warning level, a first warning prompt corresponding to the first warning level is generated, when the alarm 14 determines that the water level warning of the water level warning post 10 reaches the second warning level, a second warning prompt corresponding to the second warning level is generated, and when the alarm 14 determines that the water level warning of the water level warning post 10 reaches the third warning level, a third warning prompt corresponding to the third warning level is generated.
In this embodiment, the display screen 13 includes an early warning display area 131 and a normal display area 132, wherein the early warning display area 131 includes a first display area for displaying a village name of a village reaching an early warning, a second display area for displaying a village address of the village reaching the early warning, a third display area for displaying a current water level of the village reaching the early warning, a fourth display area for displaying an early warning level of the village reaching the early warning, and a fifth display area for displaying an emergency measure of the village reaching the early warning.
Further, the normal display area 132 includes a sixth display area for displaying a village name of a village that does not reach the early warning, a seventh display area for displaying a village address of the village that does not reach the early warning, an eighth display area for displaying a current water level of the village that does not reach the early warning, a ninth display area for time, and a tenth display area for displaying a weather forecast.
In summary, the invention shoots the water level early-warning marker post 10 by calling the public camera in rainy days, and recognizes which color of the marking disc of the water level early-warning marker post 10 is positioned in the river, so that which early-warning condition is positioned in the water level can be known, and the intelligent performance is high.
