Technical field
The utility model relates to a kind of video water-level gauge.
Background technology
Waterlevel data is the important symbol of reflection water body, water flow variation, is observation element the most basic in hydrologic survey.Water-level observation data can directly apply in the process such as planning, design, construction of the engineerings such as dykes and dams, reservoir, power station, Yan Zha, water drainage, navigation channel, bridge.
Existing river level observation mainly comprises following two kinds of modes:
(1) artificial observation: by the level scale on supervisor's visual inspection embankment, and do complicate statistics and respective record.This Traditional Man observed pattern workload is huge, when carrying out water-level observation for the engineering project such as Large River, reservoir especially, needs to arrange multiple observation station, and the distance between each observation station may be far, and now artificial observation mode is difficult to be suitable for.Level scale is arranged on embankment and belongs to perfect condition, in a lot of situation, level scale is arranged on scale mark post in fact, completing artificial observation then needs supervisor just can complete the reading of level scale by ship near scale mark post, observes difficulty very large and there is certain danger.In addition, artificial observation mode also exists larger naked-eye observation error, and accuracy and the reliability of level scale reading result are poor.
(2) sensor-based intelligence observation: in use, exist and cause measurement data to occur the situation of mistake because of sensor degradation, and the accuracy of measurement of sensor is comparatively serious by the interference ratio of the environmental factors such as temperature, cannot avoid temperature drift, accuracy cannot ensure; In order to solve the problem of temperature drift, usually adopt the mode of temperature compensation to carry out compensate for disturbances, but also there is potential faults in temperature-compensation circuit, also cannot ensure the accuracy of water level monitoring originally.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of video water-level gauge is provided, height of water level is embodied intuitively by level scale, the remote monitoring of water level is realized again by camera shooting level scale, stop the water level erroneous judgement because sensor fault, temperature drift, compensating circuit fault etc. cause, the reliability of observed result of flooding.
The purpose of this utility model is achieved through the following technical solutions: video water-level gauge, comprises visual level scale and camera, and level scale is used for immediately embodying height of water level, and camera is for taking level scale, and camera is fixedly mounted on float.
Described level scale is arranged on embankment, and video water-level gauge also comprises the support bar that fixing close embankment is arranged, and float is up and down to be arranged on support bar, matches with the gradient of embankment in the angle of inclination of support bar.
Described level scale is arranged on graduated scale, matches with the gradient of embankment in the angle of inclination of graduated scale, and float is up and down to be arranged on graduated scale; Or video water-level gauge also comprises the support bar that fixing close graduated scale is arranged, and float is up and down to be arranged on support bar, matches with the angle of inclination of graduated scale in the angle of inclination of support bar.
Described level scale is arranged on vertical marker post, and vertical marker post is vertically fixed in river.
Described float is up and down to be arranged on vertical marker post.
Video water-level gauge also comprises the support bar that vertically fixing close vertical marker post is arranged, and float is up and down to be arranged on support bar.
The beneficial effects of the utility model are:
1) intuitively, exactly height of water level is embodied by level scale, water level remote monitoring is realized again by camera shooting level scale, stop the water level erroneous judgement caused because of sensor fault, also the impacts such as the temperature drift of sensor can fundamentally be avoided, the impact of temperature-compensation circuit fault can be avoided simultaneously, what camera photographed is physics scale, and scale mark and camera all can not be subject to the impact of temperature drift, and the reliability of water-level observation result is high;
2) achieve telecommunication network monitoring, improve monitoring efficiency, reduce monitoring amount and cost, be specially adapted to the engineering fields such as Large River, reservoir, dykes and dams;
3) camera is arranged on float, guarantees that camera does adaptive lifting with the lifting of water level; Float is up and down to be arranged on vertical marker post or support bar, and when float fluctuates, the spacing of camera and level scale keeps constant, and the shooting distance of camera is stablized, and shooting effect is good.
