商业微波链路（CML）网络的数据用于科学目的正变得越来越流行，特别是用于雨率估计。然而，数据的获取和可用性仍然是一个关键问题，限制了研究的可能性。为了解决这个问题，我们开发了一个基于简单网络管理协议（SNMP）的开源数据采集系统。它能够同时记录大量cml的发射和接收信号电平，时间分辨率高达1秒。我们在爱立信德国运营这个系统，从450个cml获取数据，并将数据实时传输到我们的数据库。但是，我们的数据采集系统并不局限于特定的CML硬件模型或制造商。我们通过为不同制造商的cml运行相同的系统来演示这一点，该cml由德国的一个高山滑雪胜地运营。在那里，四个cml的数据采集同时运行，时间分辨率为1秒。我们概述了我们的系统，描述了必要的SNMP请求的细节，并展示了其操作应用程序的结果。
The usage of data from commercial microwave link (CML) networks for scientific purposes is becoming increasingly popular, in particular for rain rate estimation. However, data acquisition and availability is still a crucial problem and limits research possibilities. To overcome this issue, we have developed an open-source data acquisition system based on the Simple Network Management Protocol (SNMP). It is able to record transmitted and received signal levels of a large number of CMLs simultaneously with a temporal resolution of up to 1 s. We operate this system at Ericsson Germany, acquiring data from 450 CMLs with minutely real-time transfer to our database. Our data acquisition system is not limited to a particular CML hardware model or manufacturer, though. We demonstrate this by running the same system for CMLs of a different manufacturer, operated by an alpine ski resort in Germany. There, the data acquisition is running simultaneously for four CMLs with a temporal resolution of 1 s. We present an overview of our system, describe the details of the necessary SNMP requests and show results from its operational application.
