Antenna Control System/Satellite TV Antenna System
1. The main function
1. The main function
- Antenna real-time location of the show: ACU According to the antenna orientation, pitch and the location of the polarization axis, for coding point of view, and to display the direction, and pitch angle of polarization on the LCD screen. In order to eye-catching, the position, pitch angle is displayed by using graphical 12 × 16 dot matrix ;
- Manual control: the control key on the ACU panel, enable the antenna in the clockwise (cw), anti-clockwise (ccw), Shang Tai (up) or the next bend (down) on the direction of rotation;
- Location point: ACU can be set in accordance with the meaning of satellite antenna so that the code automatically to the target, also to refer to the current on the basis of, based on the input offset angle, so that the antenna must shift after the automatic cut-off point of view refers to the location of the set:
- Stepping track: ACU can make the antenna automatic tracking the goal with the signal level that was provided by the receiver;
- Linear polarization / circular polarization conversion: one key;
- Surface polarization adjustment: to adjust the linear polarization angle with the ACU panel key;
- Parameters: the client can input and modify the variety of parameters through the panel on the keyboard, according to the ACU menu.
- Two-speed drive: three-phase frequency converter to achieve the two-speed pitch position drive;
- Control security devices: there is a limit switch to limit the direction, polarization and pitch movement. The antenna will stop when it reach the limit position and was displayed, at the moment, the antenna can only reverse move; There is a stop switches on the PDU box, it can stop the antenna movement immediately in case of emergency;
- Control and remote control functions: PDU can control the antenna movement with local control functions and remote control functions with ACU.
