直播卫星接收机工作原理及维修策略

随着卫星技术和电子技术的快速发展,利用地球同步卫星来传输电视信号的卫星广播电视频道也在不断增多,不仅能够覆盖更广阔的面积,而且也能够提高信号传输的质量,是未来高清数字电视传播的重要发展方向。卫星电视转发器自身的功率不断增大,可以接收到的卫星电视节目也在不断增多,越来越多的卫星接收机价格也在下降,所以卫星接收机的应用范围也在不断普及。由于卫星电视接收机在日常运行的过程中经常会出现各种意外的电路故障,导致卫星电视接收机的运行效果不理想影响。为此,本文通过对于卫星电视接收机的工作原理进行分析,并且明确了电路故障的现象以及检修方法,促进直播卫星接收机运行的效率。

Working Principle and Maintenance Strategy of Direct Broadcast Satellite Receiver

With the rapid development of satellite technology and electronic technology,the number of satellite radio and television channels using geosynchronous satellites to transmit television signals is also increasing,which not only can cover a wider area,but also can improve the quality of signal transmission,and is an important development direction of high definition digital television transmission in the future.The power of satellite TV repeaters is increasing,the number of satellite TV programs that can be received is also increasing,and the price of more and more satellite receivers is also decreasing.Therefore,the application scope of satellite receivers is also being popularized.Due to various unexpected circuit failures in the daily operation of satellite television receivers,the operation effect of satellite television receivers is not ideal.For this reason,this paper analyzes the working principle of satellite TV receiver,and defines the phenomenon of circuit failure and maintenance methods to promote the operation efficiency of direct broadcast satellite receiver.
