The side of the Y direction slideway 1-11 vertical with directions X slideway 1-4 is fastened on the turning axle of Y direction potentiometer 1-2, is contained in rotationally on the side of shell 1-6 after the axle 1-17 of its opposite side is equipped with elasticity shift fork 1-16; Therefore, when rocking bar 1-10 stirs Y direction slideway 1-11 rotation, can drive Y direction potentiometer 1-2 and rotate thereupon.
Directions X slideway 1-4 and Y direction slideway 1-11 are cross setting up and down, have the gap between the two, make movable separately interference-free.In the interstitial hole after the lower end 1-13 sliding fit of rocking bar 1-10 is contained in that up and down two slideways are cross and is provided with, when moving rocking bar 1-10 when 360 degree directions are rotated, can stir directions X slideway 1-4 and Y direction slideway 1-11 simultaneously rotates, make directions X potentiometer 1-1 and Y direction potentiometer 1-2 rotate the contact position that changes potentiometer thereupon, cause the voltage signal of circuit to change.
The elasticity shift fork 1-16 that is contained in respectively on the axle 1-17 of axle 1-7 and Y direction slideway 1-11 of directions X slideway 1-4 is by the shape symmetry, two and half shift fork 1-16-1 and 1-16-2 that the through hole of position, intermediate portion is contained in respectively on a 1-7 and the 1-17 form, and the two and half shift fork 1-16-1 of elasticity shift fork 1-16 can rotate separately as scissors separately with 1-16-2.In the middle of elasticity shift fork 1-16 one end two and half shift forks collision block 1-4-1 of directions X slideway 1-4, the collision block 1-11-1 of Y direction slideway 1-11 are housed, between the elasticity shift fork 1-16 other end spring 1-8,1-18 are housed.When directions X slideway 1-4 or angle of Y direction slideway 1-11 rotation, under the collision block effect, one and the half shift fork 1-16-1 that promote among the elasticity shift fork 1-16 rotate, 1-16-2 is motionless for another half shift fork, when rotation stops, elasticity shift fork 1-16 other end spring resets directions X slideway 1-4 or Y direction slideway 1-11.
The lead 1-20 of directions X potentiometer 1-1, Y direction potentiometer 1-2, change times potentiometer 1-3 penetrates from an end of rocking bar (1-10) through hole, pass from the other end, hole from shell (1-6) side passes and is connected on the control circuit 3 again, is convenient to be transported on the control circuit 3 there being above-mentioned three potentiometers to send control signal.
The described control circuit 3 that is connected with rocking bar part 1 is single chip circuit 3-1, and single chip circuit 3-1 includes: analog/digital converter 3-2, central processor CPU 3-3, level transferring chip 3-4; Wherein three of analog/digital converter 3-2 input ends are connected with three potentiometer 1-1,1-2 of rocking bar part 1, the output terminal of 1-3, at the output terminal connection central processor CPU 3-3 of analog/digital converter 3-2; The output terminal of central processor CPU 3-3 connects level transferring chip 3-4 input end; The output terminal of level transferring chip 3-4 is connected to the serial communication interface of computing machine.
Wherein analog/digital converter 3-2 buyable is for example selected ADC0809 model chip for use, but the also single-chip microcomputer of select tape A/D function.Level transferring chip 3-4 buyable is for example selected MAX232 model chip for use.
Wherein directions X potentiometer 1-1 and Y direction potentiometer 1-2 output voltage signal control gamma camera The Cloud Terrace angle changes, becomes times potentiometer 1-3 output voltage signal control picture change doubly.
Below in conjunction with accompanying drawing operating process of the present invention is described:
Energized at first, make control circuit 3 energisings, operating personnel hold the planar any rotating rocker 1-10 of taper knob 1-12, perhaps a hand turning handle overlaps 1-12, can make directions X potentiometer 1-1, Y direction potentiometer 1-2, or become the contact position that times potentiometer 1-3 rotates the change potentiometer thereupon, the voltage signal that causes circuit output to change.The analog/digital converter 3-2 that links to each other with above-mentioned three direction potentiometers is converted to data respectively with the voltage signal of three potentiometers, and sending the central processing unit 1-2 that is attached thereto to, central processing unit 1-2 carries out obtaining Useful Information after the calculation process to these rambling data; The other end of central processing unit 1-2 links to each other with level transferring chip 1-3, and the effect of level transferring chip 1-3 is that communication signal voltage is carried out conversion, useful data is sent to the serial communication interface COM1 of computing machine by level transferring chip 1-3.Above-mentioned single chip circuit 3-1 finishes communication signal is transformed into the signal that computing machine can be discerned.Computing machine utilizes these information to connect the control input end of controlled monopod video camera by network or other serial ports COM2.
Connected mode by network control is: the network interface of computing machine connects internet or LAN (Local Area Network), and controlled The Cloud Terrace, video camera also connect internet or LAN (Local Area Network).When moving rocking bar 1-10 transmits data-signal from the rocking bar position change to computing machine, this digital signal is sent steering order by network interface or serial communication interface to controlled device through after the Computer Processing, make about controlled The Cloud Terrace or rotation up and down, the direction decision of the direction of rotating when moving rocking bar, the speed of rotation is by the angle decision of rocking bar off-center position; The rotation of taper knob 1-12 can be controlled the enlargement factor of camera lens.
The present invention realizes replacing existing computer keyboard and mouse with rocking bar, realizes that the rotation of The Cloud Terrace different angles and camera views become control doubly.
