Description
Technical field
The utility model belongs to the communications field, relates to a kind of push-down stabilized platform that is used to install reception antennas such as satellite.
Background technology
Platform in the satellite television receiving system commonly used now is the straight stable type gyropanel, and it is to lean on the high-speed gyroscopic inertia principle stabilized platform that rotates of gyro machine.Because the gyro machine of straight stable type gyropanel is under the high speed rotating state for a long time, so electrical machinery life is short, noise is big, stabilized speed is slow.
Summary of the invention
In order to improve the defective of straight stable type gyropanel, the utility model proposes a kind of push-down stabilized platform.
Realize that the technical solution of the utility model is such, below pedestal 1 center of stabilized platform, main universal drive shaft 2 is installed, main universal drive shaft lower end is connected with column 3, two push rods 5 mutually at an angle of 90, the upper end is connected apart from 150mm place, platform center by push rod universal drive shaft 4, the lower end is connected on the column 3 by the rotating shaft of push rod, motor 6 and push rod 5 parallel installations, motor shaft is connected by the ball screw of synchronous belt type decelerator with push rod 5, controller 8, motor driver 10 and slant angle sensor 9 are installed on the support 7, feedback transducer 11 is installed on X (Y) the both direction spindle nose of main universal drive shaft, slant angle sensor 9, feedback transducer 11, controller 8, be connected by electric wire between motor driver 10 and the motor 6.
The push-down stabilized platform has been used technology such as electronics, computer, machine driving, transducer, communication, control, have regulate the speed fast, lasting accuracy is high, noiseless, long characteristics of life-span, for example can being applied on the mobile vehicle, steamer, train, automobile etc. require to adjust in the high technical field of precision, in equipment such as satellite communication and satellite television reception.Also very extensive with regard to the range of application of push rod technology own in addition, as hoisting machinery, Medical Devices, Industry Control, military equipment etc.

Embodiment
1,2 pair of the utility model describes in conjunction with the accompanying drawings.Fig. 1 medium dip angle transducer is mounted on the horizontal plane of mobile vehicle, and it describes mobile vehicle rolling (X) and pitching (Y) angle value.Transducer output is represented the inclination angle size with direct voltage, the direction of waving with the positive and negative representative carrier of voltage; Differential amplifier wherein one tunnel (from obliquity sensor) is represented the signal of carrier rolling or pitching, delivers to the differential amplifier positive input; The A/D collector is the voltage signal that transducer is sent here through differential amplifier, is quantized into digital signal; CPU handles digital signal, and judgement direction, size are given controller; Controller sends instruction and makes motor rotate, and the driven by motor platform becomes reversed dip with carrier; Feedback element (feedback transducer) is mounted on the main universal drive shaft of platform, when the driven by motor platform inclination, feedback transducer is also sent a size and is given the differential amplifier negative input with the voltage signal that the slant angle sensor signal equates, direction is identical, differential amplifier subtracts each other slant angle sensor signal and feedback signal, output end signal equals zero, and platform reaches new balance.
1 is the body of platform among Fig. 2, and it is to be used to fix up an aerial wire and the pedestal of antenna tracking system; The 2nd, main universal drive shaft, it is the main strong point of platform motion; The 3rd, column; The 4th, push rod universal drive shaft, the strong point of its effect when to be push rod with platform do garden arc motion; The 5th, push rod also is the core component of stabilized platform, and it is made up of parts such as ball screw, push rod, position-limit mechanism, ratio wheel, synchronous band, motors, is the power part of stabilized platform; The 6th, direct current machine; The 7th, support is the basis of complete machine, installs with mobile vehicle to be connected; The 8th, controller; The 9th, slant angle sensor; The 10th, motor driver; The 11st, the platform feedback transducer.
Push-down stabilized platform workflow as shown in Figure 1, when carrier on X (y) direction during run-off the straight, slant angle sensor will output signal, this signal is delivered to the A/D inlet through differential amplifier, CPU commander A/D is taken into internal memory with the slant angle sensor signal, send instruction through after the processing and identification to controller, command content contains: motor speed V, direction DIR, motor driver is given in these three instructions of operation beginning RUN, motor rotates according to instruction, motor is by band decelerator drive screw mandrel rotation synchronously, the screw mandrel rotating nut moves up and down, so push rod will be pushed to or pull down (because push rod is installed on the ball screw nut), platform is rotated around main universal drive shaft by the push rod push-and-pull, because feedback transducer is installed on the spindle nose of main universal drive shaft, therefore feedback transducer will be exported one and slant angle sensor equal and opposite in direction, the signal that direction is opposite, this signal is delivered to the differential amplifier other end and obliquity sensor signal subtraction, when the difference amplifier is output as zero, reached new balance between platform and the carrier this moment, CPU sends new instruction, and motor stops operating.
In the utility model push-down stabilized platform, adopt sensor technology, Automatic Control Theory, computer technology, communication, precision optical machinery etc.The load 50kg of this platform, its adapts to carrier rolling ± 20 °, cycle 5-20 second; Pitching ± 15 ° cycle 5-20 second.This product structure is simple, rigidity good.And the space that has greatly improved.All carriers adapt to above parameter all can be used.
The utility model is being made local the change on the version and on the control mode, can do the Swaying Test Platform of two degrees of freedom and use.
