1.引言831台是国家广电总局直属发射台,担负着对世界各地的广播任务。我台拥有我国70年代自行研制的可360度全方位转动的大功率发射天线。2005年前,我台的转动天线使用的是分离元件逻辑控制方式,这种控制方式过多的需要人工操作,而且故障率高,维护困难。
1. Introduction 831 units are directly under the State Administration of Radio Launchpad, responsible for the broadcasting tasks around the world. Taiwan has our own 70 years of self-developed 360-degree rotation of all high-power transmit antenna. Before 2005, the rotary antenna of our company used the logic control method of separate components. This kind of control method requires too much manual operation, and the failure rate is high and the maintenance is difficult.
