Description

分布式天线系统的监测系统、 设备和方法 技术领域  Monitoring system, device and method for distributed antenna system
本发明实施例涉及通信领域, 更具体地说, 涉及分布式天线系统的监测 系统、 设备和方法。 背景技术  Embodiments of the present invention relate to the field of communications, and more particularly to monitoring systems, devices, and methods for distributed antenna systems. Background technique
随着社会文明的发展, 人们对信息通讯的要求越来越高, 在保证手机信 号覆盖的前提下, 如何有效的降低天线带来的电磁辐射污染, 已经成为目前 通信设备制造商及运营商日益重视的一个问题。  With the development of social civilization, people are increasingly demanding information and communication. Under the premise of ensuring the coverage of mobile phone signals, how to effectively reduce the electromagnetic radiation pollution caused by antennas has become an increasingly popular communication equipment manufacturer and operator. A problem that is valued.
降低电磁辐射, 就要降低通信信号的覆盖强度, 是以牺牲通信质量和通 信条件来交换的。 很明显, 在公共场合, 对通信环境有很高的要求, 是不适 合牺牲通信质量的;但是,在私人的物业空间内, 当业主不需要通信条件时, 就完全可以关闭天线覆盖系统以换取低电磁辐射的环境。  To reduce electromagnetic radiation, it is necessary to reduce the coverage intensity of communication signals, which is exchanged at the expense of communication quality and communication conditions. Obviously, in public, there is a high requirement for the communication environment, which is not suitable for sacrificing the quality of communication; however, in the private property space, when the owner does not need communication conditions, the antenna coverage system can be completely closed in exchange for Low electromagnetic radiation environment.
基于这些想法, 提出在实现室内覆盖时, 使用一种可控的室内分布式天 线装置。 这样, 用户可以根据需要在有通信信号覆盖和无辐射污染两种环境 中进行切换, 不会对其他用户的通信环境产生影响, 以保证在室内、 隧道及 地铁内能通信。  Based on these ideas, it is proposed to use a controllable indoor distributed antenna device when achieving indoor coverage. In this way, users can switch between communication signal coverage and non-radiation pollution according to their needs, without affecting the communication environment of other users, to ensure communication in indoors, tunnels and subways.
为保证通信质量, 需要定期对分布式天线系统进行检测, 目前运营商对 室内覆盖系统的检测室采用驻波检测和人工拨测的方法。 采用驻波检测方 式, 该方案在单通道天线系统检测中效果良好, 但是不适合拥有众多分支的 分布式天线系统。 采用人工拨测的方式, 操作成本高、 拨测频率低而且拨测 效果难于保证。 发明内容  In order to ensure the communication quality, it is necessary to regularly detect the distributed antenna system. At present, the operator uses the method of standing wave detection and manual dialing for the detection room of the indoor coverage system. With the standing wave detection method, this scheme works well in the detection of single-channel antenna systems, but it is not suitable for distributed antenna systems with many branches. The manual dialing method is adopted, the operation cost is high, the dialing frequency is low, and the dialing effect is difficult to ensure. Summary of the invention

As shown in FIG. 1, distributed antenna system 100 includes a source 110; and an antenna 120 on each distributed antenna branch. It should be understood that FIG. 1 is only an exemplary diagram of a distributed antenna system, including two antenna branches, and the number of antenna branches in an actual distributed antenna system can be selected as needed. Of course, the distributed antenna system also includes other necessary functional components, such as the above-mentioned splitters, combiners, couplers, RF cables, and the like. According to an embodiment of the invention, the distributed antenna system 100 further includes an interrogation device 130 disposed at a source end where the source 110 is located, and a response device 140 disposed at an antenna end where the antenna 120 of the distributed antenna branch is located. The interrogation device is electrically connected to the source 110 and powered by a power source that supplies power to the source 110. The monitoring signal can be transmitted via a feeder of the distributed antenna system, for example, an RF monitoring signal is transmitted for detecting the operating state of the antenna 120. The monitoring signal can be transmitted via a distributed antenna system and to the antenna 120. The response device 140 is coupled to the antenna 120 for receiving a monitoring signal transmitted by the information device, and the connection refers to a connection manner between the response device 140 and the antenna 120 for signal transmission and/or energy transmission. . Like other passive components of the distributed antenna system, the responsive device 140 is preferably a passive device that operates with the energy of the received monitoring signal. The response device 140 may be mounted on a feeder inside each antenna 120, or may be mounted on an external interface of each antenna 120, as the case may be. The response device 140 has identification information corresponding to the antenna branch associated with the response device 140. According to the embodiment of the present invention, the response device 140 is activated to receive the monitoring signal, and returns a response signal to the interrogation device 130.

根据本发明实施例, 问讯设备 130向全部响应设备 140发射监测信号, 并且接收每个响应设备 140返回的响应信号, 并根据响应信号中包含的识别 信息以及该响应设备接收到的监测信号的状态信息, 例如接收到的信号强度 数据, 可以判断对应的天线 120所在天线支路的工作状态。 例如, 在响应设 备 140 接收到的监测信号的强度衰减小于特定值时, 可以认为与响应设备 140耦接的天线 120所在的天线支路正常并给出天线支路正常的状态信息, 反之可以认为与响应设备 140耦接的天线 120所在的天线支路工作异常并给 出天线支路异常的状态信息。 根据本发明实施例, 问讯设备 130向响应设备 140发送的监测信号可以 包括编码信息, 响应设备 140接收到监测信号而被激活, 并在确定编码信息 与该响应设备 140的识别信息相符时, 向问讯设备 130返回响应信号。 根据 这种实施例, 可以通过在监测信号中携带与具体响应设备 140的识别信息对 应的编码信息, 来检测与响应设备 140耦接的天线 120所在的天线支路是否 正常, 即可以实现针对性的检测。 According to an embodiment of the present invention, the inquiry device 130 transmits a monitoring signal to all of the response devices 140, and receives a response signal returned by each response device 140, and according to the identification information contained in the response signal and the status of the monitoring signal received by the response device. Information, such as received signal strength data, can determine the operational state of the antenna branch in which the corresponding antenna 120 is located. For example, when the strength attenuation of the monitoring signal received by the response device 140 is less than a specific value, the antenna branch where the antenna 120 coupled to the response device 140 is located may be considered to be normal and the state information of the antenna branch is normal, and vice versa. The antenna branch where the antenna 120 coupled to the response device 140 is located is abnormally operated and gives state information of the antenna branch abnormality. According to an embodiment of the present invention, the monitoring signal sent by the inquiry device 130 to the response device 140 may include encoding information, the response device 140 is activated by receiving the monitoring signal, and when determining that the encoded information matches the identification information of the response device 140, The inquiry device 130 returns a response signal.

Detection.
根据本发明实施例, 为了避免多个响应设备 140同时向问讯设备 130返 回响应信号而造成信息冲突或者信息拥塞, 响应设备 140在接收到问讯设备 130发出的监测信号后, 分别进行随机时延, 然后再向问讯设备 130返回响 应信号。  According to the embodiment of the present invention, in order to prevent information collision or information congestion caused by the plurality of response devices 140 returning the response signal to the information device 130 at the same time, the response device 140 performs random delay after receiving the monitoring signal sent by the information device 130. The response signal is then returned to the interrogation device 130.
根据本发明另一种实施例, 问讯设备 130可以先向响应设备 140发送第 一监测信号,响应设备 140接收到第一监测信号而被激活,并处于准备状态, 然后问讯设备 130向响应设备 140发送第二监测信号, 该第二监测信号携带 上述编码信息, 响应设备 140接收第二监测信号, 并在确定编码信息与识别 信息相符时, 向问讯设备 130返回响应信号。 利用这种实施例, 可以避免通 过一个监测信号既向响应设备 140提供动力又指令其返回响应信号所造成的 无法接收到响应设备 140 的响应的问题。 利用第一监测信号激活响应设备 140, 而利用第二监测信号指令相应的响应设备 140返回响应信号, 可以更 为有效地保证得到正确的响应信号。  According to another embodiment of the present invention, the inquiring device 130 may first send a first monitoring signal to the response device 140, the response device 140 is activated by receiving the first monitoring signal, and is in a ready state, and then the inquiring device 130 transmits the response device 140. Sending a second monitoring signal, the second monitoring signal carries the encoded information, and the response device 140 receives the second monitoring signal, and returns a response signal to the interrogation device 130 when determining that the encoded information matches the identification information. With such an embodiment, it is possible to avoid the problem that the response of the response device 140 cannot be received by both the power supply to the response device 140 and the return of the response signal by a monitoring signal. The response device 140 is activated by the first monitoring signal, and the corresponding response device 140 is used to return the response signal by using the second monitoring signal, so that the correct response signal can be more effectively ensured.
在本发明实施例中, 响应设备 140 例如可以是无线射频识别 (Radio In the embodiment of the present invention, the response device 140 may be, for example, a radio frequency identification (Radio).
Frequency Identification, 筒称 "RFID" ) 芯片。 Frequency Identification, the tube is called "RFID") chip.
