基于ARM的射频前端自动控制与监控系统设计

ARM-based RF front-end automatic control and monitoring system design

目前船用射频收发机使用范围越来越广,射频前端工作状态控制复杂多变,为适应各种使用情况,考虑将射频前端的工作状态及环境信息进行监控,提出了一种基于ARM的射频前端自动控制与监控系统。结合射频前端中发射通道、接收通道和频综的锁定指示功能及设计环境采集电路,以ARM系列MCU(CKS32F103C8T6)作为系统控制器,详细设计出该自动控制与监控系统的核心组成部分。最后设计测试上位机模拟外部基带端进行系统联调,系统能够依据指令自动控制自身的工作状态,同时将系统的运行状态及环境变化定时反馈到外部基带端,验证了该自动控制与监控系统设计方案的合理性,提高了船用射频通信系统的准确性及稳定性。

At present,marine RF(radio frequency)transceiver is used more and more widely,and the working state control of RF front-end is complex and changeable.In order to adapt to various use conditions,considering the monitoring of the working state and environmental information of RF front-end,an automatic control and monitoring system of RF front-end based on ARM is proposed.Combined with the locking indication function of transmitting channel,receiving channel and frequency synthesizer in RF front-end and the design of environment acquisition circuit,the core component of the automatic control and monitoring system is designed in detail with ARM Series MCU(CKS32F103C8T6)as the system controller.Finally,the test host computer is designed to simulate the external baseband end for system joint debugging.The system can automatically control its own working state according to the instructions,and regularly feed back the operation state and environmental changes of the system to the external baseband end,which verifies the rationality of the design scheme of the automatic control and monitoring system and improves the accuracy and stability of the marine RF communication system.
