监控模块是发射组件的重要组成部分,主要用于状态采集和开关控制。监控模块可实现发射组件的数字量采集、模拟量采集和信息处理。同时,上位机可通过控制局域网(CAN)总线获取发射组件的工作信息,并实现射频开关控制。文中介绍了监控模块的功能和组成框图,并对硬件电路设计和软件设计作了详细介绍,对监控模块的设计提出了一些有益的建议。

The monitor and control module is the important composing part of the transmitter subassembly, which is mostly used for state collection and on-off control. The monitor and control module can achieve digital collection,analog collection and information disposal of the transmitter subassembly. At the same time, the host computer can acquire working information of the transmitter subassembly and realize RF on-off control via the CAN bus. The function and the composing frame of the monitor and control module are introduced. The hardware design and the software design are also introduced minutely. Some beneficial advices are brought forward for the monitor and control module design.
