摘要:
提出了基于全数字调制超短波电台的水文遥测终端。遥测终端以STC15F2K156为中央控制器，可进行水位、雨量等水文信息的采集，采集的水文信息通过基于全数字调制技术的超短波电台传送至中心站。对遥测终端的硬件和软件进行了设计，并设计了基于delta sigma调制器的全数字频移键控-调频电台。电台在一片FPGA上实现，最后对电台进行了测试。测试结果表明该电台符合水文遥测终端的要求。
Abstract:
A hydrologic remote test unit based on very high frequency radio with all-digital modulation technology is present. Hydrologic parameters, such as water level, rain quantity can be measured by the remote test unit. STC15F2K156 is used as the central controller. The hydrologic parameters were transmitted to center station via very high frequency radio based on all digital modulation technology. The hardware and software design was given. An all-digital frequency shift key frequency modulation (FSK-FM) radio based on FPGA was designed and measured. The measurement results were given, which indicate the proposed remote test unit satisfies the requirement for hydrologic telemeter application.
