Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a wireless communication base station. Background Art

[0002] Wireless communication base stations are mainly installed in high-rise buildings, hills, squares, roads and other places to cover a wide range of outdoor areas to provide a wide range of communication services. Wireless communication base stations mainly include main control units, RF modules, antenna arrays, power modules, etc.

[0003] The antenna array is one of the important components of the wireless communication base station, which is used to receive and send wireless signals. The existing wireless communication base station is usually deployed on the roof of a high-rise building or a hill (the base station deployment height is generally around 60m), and its antenna pitch angle is tilted downward (see the mobile communication base station antenna with patent publication number CN101826662 A) to cover the streets, buildings, roads, etc. on the ground. This wireless network deployment method can have good signal strength and quality in the space below the wireless communication base station (below 60m) where the mobile communication wireless signal has strong coverage. The space above the wireless communication base station is a weak coverage area for the mobile communication wireless signal. The space above the wireless communication base station and close to the base station (the ultra-low altitude area between 60-100m) has poor wireless signal strength and extremely poor quality. The space after rising to a certain height (the low altitude area between 100m-3000m) is even a blind spot. This makes it impossible for mobile communication users in the space above the wireless communication base station and user terminals of aircraft such as drones, helicopters, and hot air balloons to use the signals of the wireless communication base station. In particular, when drones, helicopters, hot air balloons and other aircraft are flying long distances and continuously in low-altitude areas, they cannot see, control, and transmit data in real time throughout the entire process.

[0050] See also Figure 1-Figure 2 To further illustrate a wireless communication base station of the present invention, a specific implementation is provided, which includes

[0051] The antenna base 10 comprises a base 102 and a support 101, wherein the support 101 is disposed on the base 102 and is used to support and fix a plurality of antenna systems 20;

[0052] A plurality of antenna systems 20 are stacked; each of the antenna systems 20 includes a radio frequency module and an antenna array 202; the radio frequency module of the top antenna system 20 is in a cover shape, and the radio frequency modules of the remaining antenna systems 20 are in a ring shape, so that the cover-shaped radio frequency module 201 and the ring-shaped radio frequency module 203 are stacked and abutted to form a spherical shape; the antenna array 202 of each antenna system 20 is correspondingly connected to the radio frequency module and arranged along its normal direction;

[0053] The main control unit 30 is connected to the transmission module 40 and provides operation control and data processing for each antenna system 20 in the base station as well as communication between the antenna systems 20;

[0054] A power module 50 provides working power for the base station;

[0055] The transmission module 40 is connected to the radio frequency module to provide signal transmission between the base station and the antenna system 20 .

[0056] The base 102 and the support 101 can be fixedly connected to form a complete antenna base 10, which is directly used to support and fix a plurality of antenna systems 20, such as welding the base 102 and the support 101 into one body to form a complete antenna base 10; or the base 102 and the support 101 can be independently set, and the antenna base 10 is formed by a detachable connection. When in use, the base 102 and the support 101 are connected to support and fix a plurality of antenna systems 20. When installing the base station, the base 102 is firmly mounted on the ground or other supporting structures by a set of fixing screws or other fixing devices. The antenna base 10 supports and fixes a plurality of antenna systems 20, and the support 101 can be connected to the antenna system 20 by bolts, snap-fitting or other fixing methods to fix the antenna system 20.

[0057] In the above, the plurality of antenna systems 20 distributed up and down correspond to the RF modules that are connected to form a spherical shape. The spherical shape can be a solid sphere or a hollow sphere, and its appearance shape can be spherical, hemispherical, spherical, ellipsoidal, conical (a shape composed of a hemisphere on the upper part and a cone on the lower part), etc. The antenna array 202 of each of the above-mentioned antenna systems 20 is arranged along the normal direction of the corresponding radio frequency module (spherical surface of the quasi-spherical shape) so that the wireless signal is radiated in a spherical shape, that is, the antenna array 202 of the antenna system 20 located in the lower layer of the quasi-spherical shape is tilted downward, and is used for wireless signal coverage of the ground area below the deployment height of the wireless communication base station and from the ground area to the ultra-low altitude area; the antenna array 202 of the antenna system 20 located in the middle layer of the quasi-spherical shape is arranged horizontally, and is used for wireless signal coverage of the ultra-low altitude area near both sides of the deployment height of the wireless communication base station; the antenna array 202 of the antenna system 20 located above the middle part of the quasi-spherical shape is tilted upward, and is used for wireless signal coverage of the low altitude area above the deployment height of the wireless communication base station; and continuous coverage of wireless signals from the ground, ultra-low altitude area to the low altitude area is realized.

[0058] The antenna array 202 of each of the antenna systems 20 described above is connected to the radio frequency module, which is mainly responsible for converting electrical signals into wireless signals and converting received wireless signals into electrical signals. There are many ways to connect the antenna array 202 to the radio frequency module, which can be selected according to actual needs and conditions. In some embodiments, the antenna array 202 and the radio frequency module are connected via a coaxial cable, which is simple and easy to connect and has low cost. In some embodiments, the antenna array 202 and the radio frequency module are connected using a radio frequency switch, which can control the antenna and select the best antenna for signal transmission, which can improve communication quality and reliability. In some embodiments, the antenna array 202 and the radio frequency module are connected via a digital interface to achieve high speed and stability of data transmission, and at the same time, the antenna array 202 can be quickly disassembled and assembled on the radio frequency module. Taking the digital interface as an example, the specific implementation method is further explained, that is, the radio frequency module is provided with an antenna interface unit, the antenna array 202 is provided with an antenna access unit corresponding to it, and the antenna access unit is connected to the antenna interface unit so that the antenna array 202 is connected to the corresponding radio frequency module. The connection between the antenna access unit and the antenna interface unit can be achieved by plugging, plugging, etc.

[0059] In order to reduce the occupied space of the entire wireless communication base station, so as to better meet the actual application requirements. In some embodiments not shown, the corresponding radio frequency modules can be abutted to form a hollow sphere, and the main control unit 30, power module 50 and transmission module 40 can be accommodated inside the hollow sphere, so as to reduce the volume of the entire device. At the same time, the exposed parts of the device are reduced, so as to improve the safety and protection ability of the device. Figure 2 As shown, in some embodiments, the support 101 can be set to a hollow column, that is, the support 101 has a cavity, and the main control unit 30, power module 50 and transmission module 40 are accommodated in the cavity of the support 101. The main control unit 30, power module 50 and transmission module 40 are arranged in the support 101, and these devices can be integrated into the cavity, thereby reducing the volume of the entire device. At the same time, the exposed parts of the device are reduced, thereby improving the safety and protection ability of the device, which is conducive to later maintenance and replacement, thereby reducing maintenance time and cost.

[0060] See also Figure 2 and Figure 3As shown, a wireless communication base station will generate a lot of heat when it is running for a long time. For this reason, a heat dissipation unit 70 can also be set to dissipate heat in time, reduce the temperature of the equipment, and thus improve the stability and reliability of the equipment. In particular, the excessive temperature of the RF module will reduce the performance of the equipment, such as signal quality, spectrum efficiency, etc. For this reason, the heat dissipation unit 70 may include a first heat dissipation device 701, which is set in a shape corresponding to the abutment of the RF module. It is arranged on the support 101 so that the support 101 supports and fixes the first heat dissipation device 701, and the RF modules of several antenna systems 20 are correspondingly sleeved outside the first heat dissipation device 701. The above-mentioned first heat dissipation device 701 is set in a shape corresponding to the abutment of the RF module, which means that the RF modules of several antenna systems 20 abut to form a hollow spherical shape, and the first heat dissipation device 701 is set to a spherical shape corresponding to the hollow spherical shape, so that the RF modules of several antenna systems 20 are correspondingly sleeved outside the first heat dissipation device 701. The first heat dissipation device 701 can be a heat dissipation device realized by water cooling, physical transfer heat dissipation, etc. In some embodiments, the first heat dissipation device 701 is a heat sink, and the RF module is mounted on the heat sink. The heat generated by the RF module is quickly dissipated through the large area contact of the heat sink, thereby reducing the temperature. In some embodiments, the RF module is mounted on the outer surface of a cooling water pipe, and the cooling water flows through to take away the heat of the RF module, thereby reducing the temperature.

[0061] See also Figure 2 and Figure 3 As shown, for the convenience of installation, under the premise of having a first heat sink 701, two annular RF modules 203 abutting against each other are respectively located on both sides of the middle part 7011 of the first heat sink. The middle part 7011 of the first heat sink is the position where the horizontal cross-section of the first heat sink 701 is the largest. The two annular RF modules 203 abutting against each other are located at the relatively lower layer and the RF modules below them can be mounted on the first heat sink 701 from bottom to top, and the RF modules at the relatively upper layer and the RF modules above them can be mounted on the outside of the first heat sink 701 from top to bottom.

[0062] The connection between the RF module and the transmission module 40 is to realize that each antenna system 20 in the base station provides the basis for operation control and data processing as well as communication between the antenna systems 20; there are many ways to connect the RF module and the transmission module 40, which can be selected according to actual needs and conditions. In some embodiments, the antenna RF module and the transmission module 40 are connected via a coaxial cable or a balanced cable, which is simple and easy to connect and has low cost. In some embodiments, the antenna array 202 and the RF module are connected using pins to achieve a close connection and better signal transmission quality. In some embodiments, the antenna RF module and the transmission module 40 are connected via a digital interface to achieve high-speed and stable data transmission. See Figure 2 and Figure 3 As shown, taking the digital interface as an example, the specific implementation method is further explained, that is, a radio frequency interface unit 2017 is provided on the first heat dissipation device 701 corresponding to the radio frequency module of each antenna system 20, and the radio frequency module corresponding to the radio frequency interface unit 2017 is provided with a corresponding radio frequency access unit, and the radio frequency interface unit 2017 is connected to the radio frequency access unit so that the corresponding radio frequency module is connected to the transmission module 40.

[0063] The connection between the RF interface unit 2017 and the RF access unit can be plugged in, snapped in, etc., to achieve quick assembly and disassembly of the antenna system on the first heat sink. For example, the RF interface unit 2017 can be embedded in the first heat sink 701, and integrated with the first heat sink 701, so that when the RF access unit is connected to the RF interface unit 2017, additional support can be provided for the RF module to be sleeved outside the first heat sink 701. The RF interface unit 2017 can include a power interface 20172 connected to the power module 50, a transmission interface 20171 connected to the transmission module 40, and a control circuit interface, etc. The power interface 20172 enables the power module 50 to provide power to it, and the transmission interface 20171 provides each antenna system 20 with a basis for operation control and data processing as well as communication between antenna systems 20.

[0064] When the main control unit 30, the power module 50 and the transmission module 40 are accommodated in the cavity of the support 101, the heat dissipation unit 70 may include a second heat dissipation device 702, and the second heat dissipation device 702 is set to correspond to the shape of the support 101 and is sleeved on the outside of the support 101. Similarly, the second heat dissipation device 702 can be a heat dissipation device implemented by water cooling, physical transfer heat dissipation, etc. In some embodiments, the second heat dissipation device 702 is a heat sink, and the heat sink is sleeved on the outside of the support 101. Through the large area contact of the heat sink, the heat generated by each module in the support 101 is quickly dissipated, thereby reducing the temperature. In some embodiments, the cooling water pipe is arranged on the outer surface of the support 101, and the cooling water flow takes away the heat generated by each module in the support 101, thereby reducing the temperature.

[0065] To further improve the above embodiment, an antenna protection cover 60 may be provided, and the antenna protection cover 60 corresponds to the shape setting of several antenna systems 20, and is sleeved on the outside of the antenna array 202. The antenna protection cover 60 can play a protective role, preventing the antenna array 202 from being hit, worn or damaged by external objects, and can effectively reduce the impact of natural and human factors on the antenna array 202, and extend the service life of the antenna array 202. The antenna protection cover 60 can be formed of a material with low attenuation, high temperature resistance and strong toughness. Of course, specific materials can achieve specific functions. For example, the use of electromagnetic shielding materials can prevent electromagnetic interference. In some special environments, such as around high-voltage wires or strong electromagnetic fields, the antenna may be subject to electromagnetic interference, resulting in a decrease in signal quality or failure to work properly. At this time, installing the antenna protection cover 60 can effectively isolate the antenna from the electromagnetic field of the surrounding environment and ensure the stability and reliability of the signal.

[0066] The above-mentioned radio frequency module may include a baseband processing unit 2015, a digital pre-corrector 2011, an intermediate frequency processing unit 2018, a clock unit 2016, and an nTnR transceiver unit 2012. The baseband processing unit 2015 is responsible for receiving, processing and sending digital signals, converting digital signals into radio frequency signals, and performing digital signal processing, such as encoding, modulation, demodulation and decoding. The digital pre-corrector 2011 is responsible for correcting the nonlinear distortion of the radio frequency signal, and by pre-processing the input signal, eliminating the signal distortion caused by nonlinear distortion, and improving the quality and reliability of the radio frequency signal. The intermediate frequency processing unit 2018 is responsible for down-converting the radio frequency signal to the intermediate frequency, and by mixing the radio frequency signal with the signal of the local oscillator, it is down-converted to the intermediate frequency, and the intermediate frequency signal can be more easily amplified, filtered and demodulated. The clock unit 2016 is responsible for providing the clock signal of the antenna system 20, and by generating a stable clock signal, the synchronization and accuracy of the entire antenna system 20 are guaranteed. The nTnR transceiver unit 2012 is responsible for receiving and sending radio frequency signals from the radio frequency module, and switching between receiving mode and transmitting mode.

[0067] Of course, in addition to the above, the RF module may also include PA and LNA units 2013, a combiner, and a filter 2014, which are arranged between the nTnR transceiver unit 2012 and the antenna array 202. PA (power amplifier) ​​and LNA (low noise amplifier) ​​units are usually used to enhance the signal strength and reduce noise; when transmitting a signal, the PA unit amplifies the intermediate frequency signal to sufficient RF power so that the signal can be radiated by the antenna; when receiving a signal, the LNA unit amplifies the weak RF signal received by the antenna to a sufficient intermediate frequency signal so that the subsequent processing unit can process it. The combiner is usually used to combine multiple signals into one. In the transmission mode, the combiner combines the output signals of multiple PA units into one RF signal so that it can be radiated by the antenna. In the receiving mode, the combiner combines the signals received by multiple LNA units into one intermediate frequency signal so that the subsequent baseband processing unit 2015 can process it. The filter 2014 is usually used to filter useless frequencies and interference signals. In a radio frequency communication system, filter 2014 is generally used to filter out useless frequencies and interference signals received by the antenna. In the transmit mode, filter 2014 is used to filter out useless frequencies and clutter signals in the PA unit output signal to ensure the purity and quality of the radio frequency signal. In the receive mode, filter 2014 is used to filter out useless frequencies and interference signals in the signal received by the LNA unit so that the subsequent processing unit can process it.

[0068] It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present invention specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
