技术领域technical field
本发明涉及通信技术，尤其涉及一种RRU和天线的集成模块化系统及移动通信基站。The invention relates to communication technology, in particular to an integrated modular system of RRU and antenna and a mobile communication base station.
背景技术Background technique
在TD-SCDMA（Time Division Synchronized Code Division Multiple Access；时分同步码分多址接入系统）移动通信基站系统中，RRU（Remote RF Unit，远程射频单元）+智能天线的天馈解决方案的应用较为普遍。In the TD-SCDMA (Time Division Synchronized Code Division Multiple Access; time division synchronous code division multiple access system) mobile communication base station system, the application of the antenna feeder solution of RRU (Remote RF Unit, remote radio frequency unit) + smart antenna is more universal.
如图1所示，RRU和智能天线固定于同一抱杆上，两者之间通过多根射频馈线连接，射频馈线的数量等于射频通道的数量加1（所余出的一条射频馈线为天线校准通道）。由于馈线会引入损耗（该损耗包括两部分：RRU和智能天线之间的射频馈线损耗和智能天线内部合路器和线缆的损耗馈线引入的损耗），而该损耗会影响系统的接收灵敏度，为了弥补馈线引入的损耗，RRU需提供更高的输出功率以保证覆盖要求。As shown in Figure 1, the RRU and the smart antenna are fixed on the same pole, and the two are connected by multiple RF feeders. The number of RF feeders is equal to the number of RF channels plus 1 (the remaining RF feeder is for antenna calibration. aisle). Since the feeder will introduce loss (the loss includes two parts: the loss of the RF feeder between the RRU and the smart antenna and the loss of the combiner inside the smart antenna and the loss of the cable) and the loss will affect the receiving sensitivity of the system. In order to compensate for the loss introduced by the feeder, the RRU needs to provide higher output power to ensure the coverage requirement.
虽然随着技术的发展，RRU的体积和重量都有一定的缩小，但对安装天面的需求并没有明显的改善。在TD-SCDMA产业化中期，出现了一体化天线，如图2所示，将RRU202置于天线201背部，使RRU通过连接器与天线硬连接，从而减少天线与有源设备之间的馈线连接、降低了天馈系统损耗、减小了对安装天面的需求。但由于天线外壳多采用PVC（Poly Vinyl Chloride，聚氯乙烯）、塑料、玻璃钢等材料，其硬度较低，并且由于需要采用带有一定下倾角的斜立安装在抱杆203上的方式，所以使天线外壳受RRU重量影响易产生变形，同时，该系统需要在现场进行RRU和天线的盲插安装，大大降低了产品的可靠性，难以得到广泛的推广和应用。Although the volume and weight of the RRU have been reduced to a certain extent with the development of technology, the requirements for installing the sky surface have not been significantly improved. In the mid-term of TD-SCDMA industrialization, an integrated antenna appeared. As shown in Figure 2, the RRU202 is placed on the back of the antenna 201, so that the RRU is hard-connected to the antenna through a connector, thereby reducing the feeder connection between the antenna and active equipment , Reduce the loss of the antenna feeder system, and reduce the need for installing the antenna. However, because the antenna shell is mostly made of PVC (Poly Vinyl Chloride, polyvinyl chloride), plastic, glass fiber reinforced plastic and other materials, its hardness is low, and because it needs to be installed on the pole 203 obliquely with a certain downward angle, so The antenna shell is easily deformed due to the weight of the RRU. At the same time, the system needs to be installed blindly between the RRU and the antenna on site, which greatly reduces the reliability of the product and is difficult to be widely promoted and applied.

By separately setting the main control module used for active control in the RRU, the antenna filter and the transceiver unit used for radio frequency processing in the RRU are divided into several small units and combined with the antenna array and set in the source radiation module. An antenna filter for radio frequency processing, the transceiver unit is independently combined with the antenna element in the source radiation module, so that the RRU and the smart antenna are completely integrated, and the feeder connection between the antenna and the active device is avoided. In turn, feeder losses are avoided. At the same time, the antenna, element, filter and power amplifier are arranged in the active radiation module, which is convenient for installation and improves the reliability of the system.

有源辐射模块302中包括天线阵子、天线滤波器以及收发信单元。The active radiation module 302 includes an antenna element, an antenna filter, and a transceiver unit.
由于将天线阵子和天线滤波器、收发信单元等RRU模块集成设置在有源辐射模块302中，避免了使用馈线，进而避免了馈线损耗。Since the antenna element, the antenna filter, the transceiver unit and other RRU modules are integrated in the active radiation module 302, the use of a feeder is avoided, thereby avoiding feeder loss.
其中，主控模块301为RRU中用于进行有源控制的模块。有源辐射模块302中，收发信单元实现对下行信号的混频、滤波、功率放大然后发送到天线滤波器进行滤波；对接收到的上行信号进行低噪声放大、滤波、混频然后发送到主板进行信号处理。天线滤波器完成降低发射杂散和抑制阻塞的作用，在宽带天线覆盖的频率资源下，天线滤波器可以根据不同系统的频率配置设计成相同的结构和接口，方便更换。天线阵子是天线的重要组成部分，而天线发射和接收电磁波的一个重要的无线设备，它将发射机输出的下行射频信号以电磁波的形式辐射辐射到空间中，将空间传播过来的电磁波接收下来，送到接收机。Wherein, the main control module 301 is a module used for active control in the RRU. In the active radiation module 302, the transceiver unit implements frequency mixing, filtering, and power amplification of the downlink signal, and then sends it to the antenna filter for filtering; performs low-noise amplification, filtering, and frequency mixing on the received uplink signal, and then sends it to the main board Perform signal processing. The antenna filter completes the functions of reducing emission spurs and suppressing blocking. Under the frequency resources covered by the broadband antenna, the antenna filter can be designed with the same structure and interface according to the frequency configuration of different systems, which is convenient for replacement. The antenna element is an important part of the antenna, and the antenna is an important wireless device for transmitting and receiving electromagnetic waves. It radiates the downlink radio frequency signal output by the transmitter into the space in the form of electromagnetic waves, and receives the electromagnetic waves transmitted from the space. sent to the receiver.
天线阵子、天线滤波器以及收发信单元3个模块通过层叠结构的形式分别固定在电路板上，并使用板对板的射频连接器实现信号的传递。The three modules of antenna element, antenna filter and transceiver unit are respectively fixed on the circuit board in the form of a laminated structure, and the board-to-board RF connector is used to realize signal transmission.
为了进一步保证散热效果，仍如图3所示，主控模块301具体包括：In order to further ensure the heat dissipation effect, as shown in FIG. 3 , the main control module 301 specifically includes:

The radiation module 302 is operated.
散热片323可以设置在主控模块301周围，由于在主控模块301上通常需要设置有电源接口、光接口、本地网口、透气孔和指标灯等外设，用于有源天线外部线缆的连接和指标灯状态观测，为便于操作，这些外设通常设置在主控模块301侧面，此时，散热片323可以仅设置在主控模块301两侧。The heat sink 323 can be arranged around the main control module 301. Since the main control module 301 usually needs to be provided with peripherals such as a power interface, an optical interface, a local network port, an air hole, and an indicator light, it is used for external cables of the active antenna. For the convenience of operation, these peripherals are usually arranged on the side of the main control module 301 , at this time, the heat sink 323 can only be arranged on both sides of the main control module 301 .

为了对有源辐射模块302进行良好的保护，如图5所示，可以进一步在有源辐射模块302外设置天线罩304，该天线罩304与散热器303密封连接，从而对有源辐射模块302进行保护。In order to protect the active radiation module 302 well, as shown in FIG. for protection.
天线罩304与散热器303的结合部位可以为散热器面板313的边缘，从而保证为有源辐射模块302留出足够的安装空间。The junction of the radome 304 and the radiator 303 may be the edge of the radiator panel 313 , so as to ensure enough installation space for the active radiation module 302 .
天线罩304与散热器303的结合部位可以使用密封圈进行密封，实现天线罩304与散热器303密封连接。The joint between the radome 304 and the radiator 303 can be sealed with a sealing ring, so as to realize the sealed connection between the radome 304 and the radiator 303 .
为进一步保护有源辐射模块302和主控模块301，主控模块301和散热器303之间的结合部分也可以采用密封圈进行密封，从而使得有源辐射模块302处于完全密封的状态。In order to further protect the active radiation module 302 and the main control module 301, the joint part between the main control module 301 and the radiator 303 can also be sealed with a sealing ring, so that the active radiation module 302 is in a completely sealed state.
在进行安装时，可以先将主控模块本体311固定进主控模块散热器321后，整体安装在散热器303的两组散热片323中间，通过密封圈对两者的结合部分进行密封；再将各有源辐射模块302分别安装在散热器303的另一面，使用连接器通过散热器303上的长方形开槽与主控模块301相连接；而后将天线罩304安装在散热器303上，天线罩304与散热器303的结合部位在散热器303的四周，且结合部位通过密封圈进行密封。When installing, the main control module body 311 can be fixed into the main control module radiator 321 first, and then installed in the middle of the two sets of cooling fins 323 of the radiator 303 as a whole, and the joint part of the two is sealed by a sealing ring; Install each active radiation module 302 on the other side of the radiator 303 respectively, and use a connector to connect with the main control module 301 through the rectangular slot on the radiator 303; then install the radome 304 on the radiator 303, and the antenna The junction between the cover 304 and the radiator 303 is around the radiator 303, and the junction is sealed by a sealing ring.
