Abstract

The application relates to a digital radio-frequency signal device. The digital radio-frequency signal device comprises a monitoring device and a signal conversion device; and a control terminal is connected to a digital processing device and a loop switching device of the monitoring device separately. The loop switching device is used to sequentially control the self-loop of the digital processing device and the signal conversion device according to the control of the monitoring device. The digital processing device is used to perform self-inspection on a first self-loop when the loop switching device controls a transmitting port and a receiving port to be connected to form the first self-loop link according to the control of the monitoring device, and is used to perform self-inspection on a second self-loop link when the loop switching device disconnects the self-loop of the digital processing device and controls a downlink output port and an uplink input port of the signal conversion device to be connected to form the second self-loop link, so as to generate respective self-inspection results corresponding to the self-loop links. The monitoring device is used to determine whether the respective self-loop links are faulty or not according to the respective self-inspection results. Therefore, the efficiency of signal link self-inspection is improved.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a digital radio frequency signal device, a method and a device for detecting a signal link. Background technique [0002] With the development of communication technologies, communication devices with digital radio frequency links, such as various types of base station devices, are widely used in various communication systems. The reliability of the uplink and downlink signals inside the communication equipment has an important impact on the quality of communication. Therefore, it is necessary to detect potential faults in the uplink and downlink in advance, or to detect the uplink and downlink in time. The location of the fault is essential for the operation and maintenance of communication equipment. [0003] At present, for communication equipment with digital radio frequency links, in order to detect uplink and downlink faults in time, the traditional detecti...
