Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1~2 are referred to, the present invention provides a kind of technical scheme：A kind of 8 meters of antenna rotating platforms, including a diameter of 8 meters turn
Disk 1, base 2, support frame 3 and drive mechanism 5, the bottom of the rotating disk 1 are rotatably installed in the top of base 2, institute by pivoting support 8
Drive mechanism 5 is stated at least provided with two groups, drive mechanism 5 is fixedly installed on the lower section of base 2 by installation set 4, and drive mechanism 5 is led to
Transmission mechanism and the drive connection of pivoting support 8 are crossed, the bottom of the rotating disk 1 is fixed with through pivoting support 8 and is filled with rotation combination
Put the shift fork axle that 6 rotation section top is fixedly connected, the rotation section bottom of the rotary combined device 6 coordinate be provided with it is coaxial
Two-way encoder 7, two-way encoder 7 can monitor the rotation of shift fork axle, you can realize precise positioning, follow the trail of the deflection of target
Degree.
Wherein, the encoder 7 uses incremental encoder, to avoid electromagnetic interference, the power supply and encoder of encoder 7
7 install nearby.By the azimuth information processing unit module of special design, the treatment to the initial data of two-way encoder 7 is completed.
Azimuth information processing unit receives two-way 14 with FPGA as arithmetic core（16384p/r）Serial differential delta pulse and difference
Zero pulse, is processed by clock so that ARP and ACP are easily achieved the output of 10 ± 0.5 μ s width.Because being set inside FPGA
Two-way counter has been put, the school north instruction that can be sent according to host computer, the position of dynamic adjustment ARP outputs realizes just
North correction.Because the two-way ARP and two-way ACP of the output of each encoder 7 are produced by the same signal of encoder 7, theoretical
Synchronous error between upper this two-way, as long as two-way circuit installs consistent, completely may be used only by the influence of fluctuations of signal transmission delay
To accomplish the synchronization accuracy of 50ns.In addition, in order to avoid the volume between two-way encoder 7 caused by alignment error and driving error

End is meshed with the rotation outer ring 10 of pivoting support 8 by little gear 9 and is connected.
The drive mechanism 5 is provided with two groups, and corresponding two little gears 9 are symmetrically distributed in the both sides of pivoting support 8.
The bottom surrounding of the base 2 is fixed with support frame 3, facilitates turret systems to place and fixes.
Operation principle of the invention is：During work, console sends work order, and drive mechanism 7 brings into operation, by passing
Motivation structure drives pivoting support 8 to rotate, and the antenna that the drive of pivoting support 8 is installed on the turntable 1 carries out continuous rotation sweep；Shift fork
The rotating part that axle can be rotated combination unit 6 is rotated, and the rotary joint in rotary combined device 6 can believe firing frequency
Number on antenna receiver；Can realize that rotating speed stepping is adjustable by adjusting frequency converter output frequency, so as to realize the multistage of turntable
Rotating speed rotates, and realizes the real-time tracking positioning to target；The coaxial mounted mode of two-way encoder 7 is employed, can be avoided
The generation of synchronous error, namely meet the synchronous error index in system requirements；By using freewheel clutch so that rotating disk
1 can automatically switch between single motor or bi-motor or many electrical machine working modes, when motor electric current exceed threshold value or
When temperature is too high and breaks down, console can automatically switch to another motor work or simultaneously machine work, play strong wind
When, and machine work, be conducive to improving the reliability and stability of system operation, realize the accurate tracking positioning to target；Employ to
Few two sets of drive mechanisms 5, have been capable of achieving the seamless switching between at least two sets drive mechanisms 5 so that whole system can carry out height
Reliable not intermittent running and on-line maintenance.
