摘要
为了对大型对数周期天线阵列进行伺服控制,实现天线阵列中单轴转台俯仰方向的运动控制,设计并实现了大型对数周期天线阵列伺服控制系统。系统的主控制单元通过CAN总线与天线阵列中各天线驱动控制单元通信。除主控制单元触摸屏外,PC上位机通过主控制单元配置扩展网络接口模块,可对天线阵列进行远程控制,无需专人值守;应急手持设备在主控制单元或CAN总线故障时,可单独控制天线阵列中任一天线运动。运行结果表明,本系统已在16个大型对数周期天线构成的阵列中使用,能单独控制某个天线、控制某几个(或所有)天线同时同向或异向转动,或通过角度设置使天线转动到确定的角度,位置精度达到0.1°,运行状态稳定良好,可靠性高。能够满足大型对数周期天线阵列的控制要求,可应用于大部分大型对数周期天线阵列,有较高的应用价值,能为大型天线阵列控制提供参考。
In order to perform servo control on a large log-periodic antenna array and realize the control of the pitch direction of the single axis rotary table in the antenna array, a large log-periodic antenna array servo control system is designed and implemented . The main control unit of the system is designed to communicate with each antenna drive control unit in the antenna array via the CAN bus. In addition to the touch screen of the main control unit, the antenna array can be controlled remotely and unattended by the PC upper computer through the extended network interface module configured by the main control unit. The emergency hand-held device is designed to control the movement of any antenna in the antenna array individually when the main control unit or CAN bus fails.
The running results indicate： The system has been used in an array which is composed of 16 large log-periodic antennas. It is able to control an antenna individually and control some （or all） antennas to rotate in the same direction or in opposite directions, or rotate the antenna to a certain angle by angle setting. The position accuracy of the system reaches 0.1 degree with stable running and high reliability. The system can fulfill the control requirements of large log-periodic antenna arrays, and can be applied to most large log-periodic antenna arrays. It can provide references for the control of large antenna arrays with high application value.
