Problems solved by technology

[0002] In water conservancy engineering facilities, the use of fishways is very common. Because water conservancy engineering equipment often needs to cut off rivers, fishways are channels for fish to migrate upstream and play a very important role in ensuring biodiversity. Most of the fishways do not carry out real-time monitoring of the number of fish passing through, the types of fish and the unimpeded conditions in the fishway, so that it often happens that it is difficult or even impossible for fish to pass through the fishway. Now a real-time monitoring system is needed. , Convenient maintenance and repair monitoring system to solve the above problems

Abstract

The invention discloses a visual fish passing monitoring system and a monitoring method in a vertical slot type fishway. The monitoring system comprises a vertical slot type fishway of which one side is provided with a movable door, and one side of the movable door is provided with a fish corral; the other side of the vertical slot type fishway is provided with a window frame of which the middle part is made of tempered glass, the tempered glass is in bolt connection with a sensor bolt; one end of the sensor bolt is provided with a sensor group; one side of the window frame is externally connected to an operating room which is internally provided with a gear motor fit to a drive sprocket, and the drive sprocket is fit to a driven sprocket through a chain fit to a camera carrier which is provided with a set of cameras; the sensor group and the cameras are all connected to computers; and in addition, the invention also discloses a corresponding monitoring method. The monitoring system and the monitoring method, disclosed by the invention, can be used for monitoring fish species in the fishway, number of fishes passing through the fishway, and smooth conditions in the fishway in real time, so that convenience is provided for management personnel to know the operation situation of the fishway and dispose in time.

Description

technical field [0001] The invention relates to the technical field of fishways, in particular to a visual fish passing monitoring system and a monitoring method in a vertical slit fishway. Background technique [0002] In water conservancy engineering facilities, the use of fishways is very common. Because water conservancy engineering equipment often needs to cut off rivers, fishways are channels for fish to migrate upstream and play a very important role in ensuring biodiversity. Most of the fishways do not carry out real-time monitoring of the number of fish passing through, the types of fish and the unimpeded conditions in the fishway, so that it often happens that it is difficult or even impossible for fish to pass through the fishway. Now a real-time monitoring system is needed. , Convenient maintenance and repair monitoring system to solve the above problems. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned ...
