摘要
根据目前大型电视演播厅布光的现状及存在的主要问题，采用FX系列可编程控制器技术研制出大型电视演播厅布光控制系统，并采用阵列方式大大减少PLC的输出点数，降低了整个系统的成本，该系统能实现对100～144盏灯的升降、左右旋、仰俯、聚散焦控制，并已经在现场推广应用。
According to present situation of large-scale television studio＇s light arrangement and in order to solve the remaining main problems, we developed the digital light arrangement control system of the large-scale television studio by adopting the application of programmable logic controllers of FX system. By using the array pattern, we reduced greatly the output contacts of PLC and the cost of whole system. The system can control 100 - 144 lights, making them be up and down, face upward and downward, whirl left and right, focus and unfocused. And it has been applied in the spot.
