Description
Technical field
The present invention relates to cradle head control technology, specifically a kind of three axis is brushless from steady tripod head controlling device.
Background technology
Currently, with the development of economy and society, people are higher and higher for wanting the requirement for shooting ground picture in high-altitude, it is
The shooting visual field can be expanded, be convenient for remote operation, often by means of holder, i.e., video camera is mounted on holder, passes through holder
Rotation axis on device rotates to drive video camera to rotate, while camera lens parameter, cloud is arranged by cradle head control agreement
Platform plays very important effect in camera system, and holder technology is rapidly developed and gradually started using each at present
Field, cradle head structure at present on the market is complicated, and the device on its device is expensive, and entire cradle head device is caused to be built into
This height.
Invention content
The purpose of the present invention is in view of the deficiencies of the prior art, and it is brushless from steady tripod head controlling device to provide a kind of three axis.
This installation cost is low, can reduce camera shooting during shake, can improve image real-time, reliability, stability, this dress
Set flexible and convenient to use, maintenance simply.
Realizing the technical solution of the object of the invention is：
It is brushless from steady cradle head control unit and six axis being attached thereto from steady tripod head controlling device, including three axis that a kind of three axis are brushless
Sensor, DC brushless motor and external control terminal.
It includes that microcontroller and the totem being connect with microcontroller drive that three axis is brushless from steady cradle head control unit
Module, voltage source module and wireless communication module.
Six axle sensor is responsible for acquiring gyro raw data and acceleration initial data, microcontroller pass six axis
The collected initial data of sensor carries out posture fusion resolving and obtains the brushless angle to deflect from steady holder of three axis；
The DC brushless motor is brushless from steady cloud to carry out three axis for driving the brushless rotation from steady cloud platform rotation axis of dynamic triaxial
The process of each posture angle compensation of platform.
The external control terminal is terminal, brushless from steady cradle head control list to three axis for sending control instruction
Member, control instruction include sending the adjustment brushless rotation from each axis of steady holder of three axis, and the holder after rotation has new reference
Origin reaches best shooting effect from steady process.
Three axis is brushless to be connect by included I/O port with six axle sensors from the microcontroller of steady cradle head control unit,
Holder will be obtained after the collected original data processing of six axle sensors because the compensation angle at inclination angle, microcontroller occur for external disturbance
According to compensation angle, three tunnel PWM waves of output, which export, gives totem drive module, and totem drive module drives driving brush DC electricity
Machine realizes pour angle compensation with the brushless rotation from steady cloud platform rotation axis of dynamic triaxial, eliminates effect of jitter, realizes from steady process.
This installation cost is low, can reduce camera shooting during shake, can improve image real-time, reliability, stabilization
Property, this device is flexible and convenient to use, it is simple to safeguard.
Description of the drawings

In figure, 1. 6 axle sensor, 2. microcontroller, 3. voltage source module, 4. totem drive module, 5. brush DC
6. wireless communication module of motor, 7. outside control terminal.
Specific implementation mode
The content of present invention is further elaborated with reference to the accompanying drawings and examples, but is not limitation of the invention.
Embodiment：
Referring to Fig.1, a kind of three axis are brushless from steady tripod head controlling device, including three axis are brushless connects from steady cradle head control unit and therewith
Six axle sensors 1, DC brushless motor 5 and the external control terminal 7 connect.
It includes that microcontroller 2 and the totem being connect with microcontroller 2 drive that three axis is brushless from steady cradle head control unit
Dynamic model block 4, voltage source module 3 and wireless communication module 6.
The model that six axle sensor 1 uses is MPU6050, is responsible for acquisition gyro raw data and acceleration is original
The collected initial data of six axle sensors 1 is carried out posture fusion and resolves that obtain three axis brushless from steady cloud by data, microcontroller 2
The angle that platform deflects；
The model that the DC brushless motor 5 uses is C2805, three axis are brushless from each axis of steady holder each direct current
Brushless motor, it is brushless from each attitude angle of steady holder to carry out three axis for driving the brushless rotation from steady cloud platform rotation axis of dynamic triaxial
Compensation and the process stablized.
The external control terminal 7 is terminal, brushless from steady cradle head control list to three axis for sending control instruction
Member, control instruction include sending the adjustment brushless rotation from each axis of steady holder of three axis, and the holder after rotation has new reference
Origin reaches best shooting effect from steady process.
Three axis is brushless to be connected from the microcontroller 2 of steady cradle head control unit by included I/O port and six axle sensors 1
It connects, holder will be obtained after six axle sensors, 1 collected original data processing because the compensation angle at inclination angle, micro-control occur for external disturbance
Device 2 processed is exported according to compensation angle, three tunnel PWM waves of output to totem drive module 4, and totem drive module 4 drives driving straight
Brushless motor 5 is flowed with the brushless rotation from steady cloud platform rotation axis of dynamic triaxial, is realized pour angle compensation, is eliminated the influence of shake, realizes
From steady process.
In this example：It is microcontroller 2, six axle sensors 1 and totem drive module that control unit, which is equipped with voltage source module 3,
4 power supplies.
