The utility model discloses not only can avoid doing with the help of the physics device and detect the problem of bringing away the line complicated zero point, problem that the camera of also having avoided the camera to cause with limit structure's continuous collision when the agretope simultaneously damaged.
Description
Technical field
The utility model relates to field of video monitoring, and particularly a kind of have the monopod video camera detecting function at zero point.
Background technology
On Vehicles Collected from Market, The Cloud Terrace class video camera normally carries out detection at zero point by physical device (such as open the light in optical interruption device, contact).This kind of physical device is complicated at the inner cabling of video camera, does not meet the designing requirement of camera chain simplicity.In the utility model, all monopod video cameras mentioned belong to sensu lato definition, therefore not only comprise the sense stricto monopod video camera driving camera lens to rotate by cloud platform rotation, also comprise the video camera that the Direct driver camera lenses such as such as ball machine rotate.
And undertaken detecting the problem causing the inner cabling complexity of video camera zero point by physical device to solve on the market, usually when video camera turns to maximum angle (agretope namely defined in the utility model), by the shock number of times that software counting video camera produces with the position limiting structure of video camera when low turn of agretope or resistance turn, if counting exceedes threshold value, think that video camera arrives agretope.Although these class methods solve the problem of cabling complexity, do not need extra additional device, but it is known by motor inherent characteristic, motor is when low turn or resistance turn, produce the large and motor of moment be in the environment that low turn or resistance turn for a long time under easily hot, therefore such scheme is very easy to the damage causing monopod video camera equipment itself, and easily causes burn-down of electric motor.
Summary of the invention
The utility model provides a kind of monopod video camera with measuring ability at zero point, not only can avoid doing zero point by physical device and detect the problem of cabling complexity brought, it also avoid video camera simultaneously and collide the problem that the video camera that causes damages at agretope place and position limiting structure continuously.
A kind of monopod video camera, comprise motor, electric-motor drive unit and control module, electric-motor drive unit is controlled by control module and drive motor rotates, low turn or resistance turn when video camera rotates and arrives agretope under driven by motor, current detecting unit is provided with between electric-motor drive unit and motor, described current detecting unit detects the current signal of motor and the current signal detected is transported to control module, the change of the size of current of the motor detected according to current detecting unit by control module, judges whether video camera is positioned at agretope.
Preferably, the agretope setting video camera is null position.
Preferably, current/voltage signal conversion unit is provided with between described current detecting unit and control module.
Preferably, video camera rotate in horizontal and vertical direction all restricted position time, then all connect a current detecting unit at the drive motor of video camera respectively in horizontal and vertical rotation direction.
Preferably, described current detecting unit is a sampling resistor.
The utility model detects the current signal size of motor by current detecting unit, judge whether video camera is positioned at agretope by control module according to curent change, thus determine the null position of video camera, do not need additional device to carry out detection at zero point, equipment cabling is simple, and little to device damage.
Accompanying drawing explanation
Fig. 1 is the utility model hardware circuit diagram;
Fig. 2 is that the utility model realizes schematic diagram.
Embodiment
A kind of monopod video camera with measuring ability at zero point of the present utility model has when turning to maximum angle, cannot continue to rotate forward owing to being provided with position limiting structure, make motor be in low turn or resistance turn feature.Definition position for video camera is agretope in the position of position limiting structure.Be exemplified below, if monopod video camera horizontally rotates scope at 0 ° ~ 355 °, now the position of 0 ° and 355 ° may be defined as agretope.
Composition graphs 1, usual monopod video camera at least comprises motor, electric-motor drive unit and control module, and electric-motor drive unit is controlled by control module and drive motor rotates, and video camera rotates under driven by motor.The utility model, by arranging a current detecting unit between motor and electric-motor drive unit, detects the current signal of motor, and the current signal detected is sent to control module.Judge whether the rotation of video camera arrives agretope by control module according to the change of motor current signal.
First it should be noted that, according to the inherent characteristic of motor, the size of motor speed and electric current is inversely proportional to, and when motor high-speed rotation, the electric current that motor exports is little, and when electric motor rotation resistant or low turn, the electric current that motor exports is large.Therefore composition graphs 2 more clearly can describe out the principle that the utility model realizes, specific as follows.Upon power-up of the system, driven by motor video camera quick rotation, current detecting unit starts in real time or periodically detects the current signal of motor and be transferred to control module.Judge whether current value obviously becomes large, if so, then judges that position for video camera is in agretope this moment, otherwise continues to detect by control module.Judge that electric current is obviously become large method and can be realized by the method for setting threshold value, so can avoid the erroneous judgement that current disturbing produces.As an embodiment of current detecting unit, can be a sampling resistor, can certainly be other integrated current detection circuit plates.
As a kind of preferred embodiment, the null position of the video camera position that can be agretope also can be after turning over a set angle after video camera to agretope, such as arranging the position turning over 2 ° after video camera arrives agretope is the null position of video camera.Certainly with the agretope of video camera for zero point, when control module judges to arrive agretope, directly automatically recording this position is zero point, and error is little.
As a kind of preferred implementation, a current/voltage-converted unit can be connected again between current detecting unit with control module, the current signal detected is converted to voltage signal, re-sends to control module, the detection signal that control module is obtained is more stable.
If above-mentioned monopod video camera horizontal and vertical rotation direction all restricted position time, the motor then actuated camera horizontal and vertical rotation direction rotated all connects a current detecting unit, detects respectively the current signal of horizontal direction and vertical direction motor.If certainly in the horizontal direction rotational angle be 0 ° ~ 360 ° can the ball machine of continuous rotation, then cannot be realized by this scheme of the present utility model, the program can only be used on ball machine vertical rotation direction.
The control module mentioned in the utility model can be a singlechip chip or other hardware controls chips.
Also will point out, the monopod video camera mentioned in the utility model is a kind of definition of broad sense simultaneously, and the monopod video camera not only comprising narrow sense also includes the rotating spherical camera of camera lens.The utility model not only can be avoided doing zero point by physical device and detect the problem of cabling complexity brought, it also avoid simultaneously video camera when agretope and position limiting structure collide the problem that the video camera that causes damages continuously.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the present invention, all within spirit of the present utility model and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the utility model protects.
