技术领域technical field

本发明涉及通信技术领域，具体地，涉及一种链路增益自适应的方法、装置、计算机设备及存储介质。The present invention relates to the field of communication technologies, and in particular, relates to a link gain adaptive method, device, computer equipment and storage medium.

背景技术Background technique

随着4G网络的大规模使用以及5G网络的逐步普及，时分双工(Time DivisionDuplex,简称TDD)模式以沉默通信领域中的主流和标准，TDD模式的特点在于时分双工，即收发使用同一频段并通过分时控制收发链路的开启和关闭。有源分布系统中包括主机单元(AU)、扩展单元(EU)和远端单元(RU)，主机单元与扩展单元之间可采用光纤传输，扩展单元与远端单元之间可以采用模拟馈线传输。由于模拟馈线的长度、材料、制作工艺以及生产时间都会对线缆的插损造成影响，为了保证系统的稳定性和工程的便利性，需要测量出馈线的插损并通过系统的增益补偿方法来抵消馈线的插损，从而保证整个通信系统的增益平衡。With the large-scale use of 4G networks and the gradual popularization of 5G networks, the time division duplex (Time Division Duplex, referred to as TDD) mode to silence the mainstream and standard in the field of communication, TDD mode is characterized by time division duplex, that is, using the same frequency band And control the opening and closing of the sending and receiving link by time sharing. The active distribution system includes the main unit (AU), expansion unit (EU) and remote unit (RU). Optical fiber transmission can be used between the main unit and the expansion unit, and analog feeder transmission can be used between the expansion unit and the remote unit. . Since the length, material, manufacturing process and production time of the analog feeder will affect the insertion loss of the cable, in order to ensure the stability of the system and the convenience of the project, it is necessary to measure the insertion loss of the feeder and use the system gain compensation method to Offset the insertion loss of the feeder to ensure the gain balance of the entire communication system.

现有技术中公开了可以通过在扩展单元发送一个点频信号给远端单元，由远端单元检测出该点频信号的功率并根据该功率的大小检测出线缆的插损，从而根据插损调整系统的增益；然而，通过发送点频信号来检测线缆的插损需要另加增加信号发送装置，从而导致成本加大；再者，如果所述点频信号是在带内发送，即在工作频段内发送，会对系统的工作信号产生干扰，在干扰严重的情况下，系统需要停止覆盖信号来进行增益的调整，调整完成后才能继续工作，这并不符合通信覆盖系统的设计；如果所述点频信号是在带外发送，即在工作频段外发送，由于模拟馈线的长度、材料、制作工艺以及生产时间会对线缆的插损造成影响，导致检测的实际插损并不准确，使得增益调整的准确率降低。It is disclosed in the prior art that an extension unit can send a point frequency signal to the remote unit, and the remote unit can detect the power of the point frequency signal and detect the insertion loss of the cable according to the power, so that according to the insertion loss adjustment system gain; however, to detect the insertion loss of the cable by sending a point frequency signal requires an additional signal transmission device, resulting in an increase in cost; moreover, if the point frequency signal is sent in-band, that is Sending in the working frequency band will interfere with the working signal of the system. In the case of severe interference, the system needs to stop the coverage signal to adjust the gain. After the adjustment is completed, it can continue to work, which does not conform to the design of the communication coverage system; If the point frequency signal is sent out-of-band, that is, outside the working frequency band, the actual insertion loss detected will not be Accurate, which reduces the accuracy of gain adjustment.

另外，现有的有源分布系统多为多制式系统，即为包含了2G、3G、4G、5G等制式的系统，频率跨度大，不同的频率对信号的响应不同，存在线缆平坦度的问题，从而无法精准测量出线缆的插损。In addition, most of the existing active distribution systems are multi-standard systems, that is, systems that include 2G, 3G, 4G, 5G and other standards. The frequency span is large, and different frequencies have different responses to signals. Therefore, it is impossible to accurately measure the insertion loss of the cable.
