Compared with prior art, adopt checkout equipment of the present utility model not need manual intervention just can carry out the automatic detection of multiposition posture difference to movement, not only shortened detection time, improved the handling capacity of streamline, and improved accuracy of detection and consistance, avoided the generation of omission situation.
Description of drawings
Fig. 1 is the structural representation of the utility model pick-up unit.
Fig. 2 is the structural representation of the main circuit board of pick-up unit shown in Figure 1.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, understands its practical novel purpose, specific structural features and advantage with further.
The preferred embodiment of the utility model pick-up unit as shown in Figure 1.The motherboard 5 that this pick-up unit comprises base 13 and is installed in rotating mechanism on the base 13, main circuit board 12, the portable camcorder apparatus movement of carrying (not shown).Rotating mechanism is made up of direct current generator 10 and shaft joint 8, is fixed on the base 13 by electric machine support 9 and bearing bracket stand 6 respectively.Shaft joint 8 near bearing bracket stand 6 is provided with position transducer, is light shading type sensor 7 in the present embodiment, and is provided with four, is used to detect the position data of motherboard 5.Power switch 11, LED lamp and four control knobs 1 are installed on the main circuit board 12.Described LED lamp comprises that a power light 3 and some functional indicator lights 2 represent the duty of circuit loops in power supply and the main circuit board 12 respectively.Have circuit in the motherboard 5, and electrically connect with movement.Motherboard 5 relies on two support bars 4 to support, and is convenient to the loading and unloading of movement, as 0 ° of loading position that the position is exactly a movement among Fig. 1.Motherboard 5 is rigidly secured on the shaft joint 8, and along with the rotation of shaft coupling 8 movement is turned on the preset detection position and to detect.
When adopting this pick-up unit to detect, the control knob 1 of start-up control rotating mechanism motion at first, rotating mechanism is clockwise direction rotation among Fig. 1 towards the direction of no support bar 4, drives motherboard 5 and movement and arrives the detection position as 300 °, 90 °, 270 °.Everyly reach a detection position, described light shading type sensor 7 will feed back to main circuit board 12 with the position data of movement on the motherboard 5, and main circuit board 12 will send inverse current rotating mechanism is locked in the detection position, convenient movement is detected debugging.
Described main circuit board 12 has a plurality of circuit control modules, comprise that loop 123 and man-machine interface circuit 124 (promptly being connected corresponding with LED lamp 2,3) take place for the upset motor control loop 121 of the central controller (Main Control Unit is called for short " MCU ") 120, the rotation of control rotating mechanism and the locking that are connected with control knob 1, core motor control loop 122, the adjustable voltage that movement is detected.Wherein MCU120 comprises 7 pins, pulse-length modulation (pulse width modulation, be called for short " PWM "), direction, motherboard position probing, adds Unloading Control, the detection of movement interior location, voltage and man-machine interface.
In the testing process, start the control knob 1 of corresponding upset motor control loop, the PWM of MCU120 goes out the velocity of rotation command signal by human hair combing waste, the direction pin sends the rotation direction command signal, all steering controling circuit 1210, H shape motor-drive circuit (being the full-bridge type motor-drive circuit) 1211, the ∫ voltage smoothing circuit (being integration voltage smoothing circuit) 1212 of input upset motor control loop 121 successively rotate thereby drive the direct current generator 10 corresponding with this upset motor control loop 121.Under the drive of direct current generator 10 and shaft joint 8, motherboard 5 related movements (not shown) rotate, and in rotation process, and four light shading type sensors 7 constantly feed back to the electric signal of the position data of motherboard 5 the motherboard position probing pin of MCU120.When turning to the detection position that needs, MCU120 sends the signal of reverse voltage, offsets moment of inertia with the method that applies the continuation reverse voltage, thereby direct current generator 10 is locked in the detection position.300 °, 270 °, 90 ° of detection positions in the present embodiment, but the detection position of pick-up unit of the present invention can be the optional position between 0 ° to 300 °.
Start the control knob 1 of corresponding core motor control loop 122, the Unloading Control pin that adds of MCU120 sends the core motor control loop sent and detects instruction, command signal is the steering controling circuit by core motor control loop 122 1220 and turn to translation circuit 1121 successively, the loading motor (not shown) that driving is positioned at movement rotates, carrying out the posture difference in the detection position of locking detects, then testing result is imported three mode switch testing circuits of movement, carry out photoelectricity then and isolate, the movement interior location of at last testing result being imported MCU120 detects pin.
Poor for the posture that can test the video camera movement under the low-voltage, the regulator (not shown) that loop 123 electrically connects takes place in the mounted on surface of this main circuit board 12 and adjustable voltage.During the posture difference of the video camera movement under detecting low-voltage, rotation regulator, but the big voltage drop that power supply can be provided by the voltage pin is low to moderate in the range of receiving.
Adopt pick-up unit of the present utility model not need manual intervention just can carry out the automatic detection of multiposition posture difference to movement, the time of detecting can be reduced to original 83.3%, misuse rate and loss all reduce more than 50%, have improved the handling capacity of streamline.Electromechanics is highly integrated, and volume reduces, and has dwindled floor area.Adopt automatic detection device of the present utility model to improve accuracy of detection and consistance.
Foregoing description; only being the description to the utility model preferred embodiment, is not to any qualification of the present utility model, for the person of ordinary skill of the art; can carry out simple modification, interpolation, conversion according to above-mentioned disclosure, and all belong to the content of protecting in claims.
