Description

Technical Field

[0001] The present invention relates to the field of microwave communication technology, and in particular to a micro base station control system based on community buildings. Background Art

[0002] With the development of mobile communication technology, the frequency is getting higher and higher, and the communication distance is getting shorter and shorter. At present, the communication distance between 5G base station equipment and mobile terminals is usually within 800m, which means that macro base stations alone can no longer cover most communities or residential areas. This problem is more serious than in the 4G era, so it is inevitable that 5G base stations will enter residential areas.

[0003] With the large increase in the number of 5G base stations, the effectiveness of 5G base station investment is an issue that must be considered. Usually, it is necessary to cover workplaces, living places and transportation. Since there are clear owners or government departments in workplaces and transportation, both macro base stations and micro base stations are much simpler to implement, and the requirements for the appearance of the product are much lower. Living places are composed of a large number of communities or communities, which are usually managed by the property management committee and property management. This makes it difficult for 5G base stations to enter the community. The first difficulty is whether the community agrees to install, and the second is the trouble of getting electricity and erecting poles during installation. Many times, after finally installing it, it has to be removed due to the opposition of several nearby families. This has already been highlighted in the 4G era. For this situation, mobile operators or tower companies have also thought of many ways, such as building pseudo base stations for street lights and greening base stations for cement trees. At this time, they encountered the inconvenience of getting electricity all day and the difficulty of laying optical fibers, so that there are still many communities or high-rise buildings without 4G signals.

[0004] The coverage of 5G signals in daily life is divided into community public space signal coverage and home coverage. If these two community scenarios are covered, the problem of 5G signal coverage in daily life will be basically solved. Home signal coverage can be solved by signal entry, but in terms of community public space signal coverage, some existing implementation methods are not desirable. In reality, the public activity space in the community is basically surrounded by various unit buildings. How to use the various entrance doors of the community unit buildings to carry out micro base station transformation has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The purpose of the present invention is to provide a micro base station control system based on community buildings, in which household anti-theft doors, floor unit doors and community gates in the community are deployed as micro base stations, thereby facilitating full coverage of mobile signals in community public spaces.

[0006] In order to achieve the above object, the present invention provides a micro base station control system based on community buildings, the system comprising:

[0007] Micro base stations are embedded in doors distributed in buildings across communities;

[0008] The microwave communication device is arranged outside the door and performs microwave communication with the micro base station.

[0009] Furthermore, the micro base station also includes a micro base station main control device and a microwave panel made of microwave communication materials, and the microwave panel is provided with a microwave antenna for communicating with the micro base station main control device.

[0010] Furthermore, the microwave communication device includes an optical fiber microwave conversion device for performing microwave communication with the micro base station, and the optical fiber microwave conversion device is connected to the laid optical fiber; wherein the micro base station has a microwave digital conversion device for performing wireless communication with the optical fiber microwave conversion device.

[0011] Furthermore, the microwave antenna is a TD-standard uplink and downlink multiplexing antenna, and the TD-standard uplink and downlink multiplexing antenna is located at the center of the microwave panel.

[0012] Furthermore, the microwave antenna is an FD-standard uplink and downlink separate antenna, wherein the uplink and downlink separate antennas are located in the upper and lower center positions of the microwave panel and are distributed left and right with a spacing greater than 20 cm.

[0013] Furthermore, the door is a household anti-theft door, or a unit door of each unit in a building, or a gate for entering or exiting a community.

[0014] Furthermore, the micro base station and the gate share a same DC power supply, which is converted into a DC power supply of a required voltage level through a DC / DC module of each device in the micro base station.

[0015] Furthermore, the micro base station converts the external 220V mains power into direct current through an AC / DC converter, and converts it into direct current power supply of the required voltage level through a DC / DC module of each device in the micro base station.

[0016] Furthermore, the optical fiber microwave conversion device and the microwave digital conversion device are located at the same height and arranged opposite to each other, and the microwave digital conversion device is installed in the door.

[0017] Furthermore, the micro base station adopts 5G signals, the optical fiber is also 5G optical fiber, and the micro base station main control device is connected to the microwave antenna through a 50Ω coaxial cable.

[0018] Compared with the prior art, the micro base station control system based on community buildings provided by the present invention has the following beneficial effects:

[0019] The present invention uses the household anti-theft doors of community buildings, the unit doors of unit buildings, and the gates entering and exiting the community as micro base stations for mobile signals. On the one hand, it is convenient to select the above-mentioned doors for power supply, and they are very close to the weak current well where the optical fiber is located, and the optical fiber resources are ready. At the same time, the anti-theft doors of the unit buildings have a large clearance environment inside and outside, and the central part of the anti-theft door can be easily transformed into a mezzanine environment that is convenient for microwave transmission, which is convenient for the arrangement of microwave antennas. This unified microwave working environment greatly reduces the installation and debugging requirements and workload of micro base stations. In addition, the community, as a scene for residents' lives, is mainly residential, with necessary public activity spaces, such as internal roads, green areas and public activity spaces in the community. These public activity spaces are basically surrounded by unit buildings. Using the doors of each unit building as a signal micro base station is not only convenient to implement, but also can basically achieve full signal coverage of the community's public spaces.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0023] See also Figure 1 As shown, this embodiment provides a micro base station control system based on a community building, and the system includes: a micro base station, and a microwave communication device for performing microwave communication with the micro base station.

[0024] The micro base station is embedded in the door 1 distributed in each community building. The door 1 can be a household anti-theft door on each floor, a unit door of each unit building, or a community gate at the entrance and exit of the community; in order to facilitate the installation of the micro base station, it is necessary to set up a storage space in the door. Taking the household anti-theft door as an example, the central center of the anti-theft door is set to be hollow to accommodate the micro base station. The micro base station is small in size, does not require a machine room, and is easy to install; it should be understood by those skilled in the art that the micro base station can be established based on 5G signals, that is, 5G signal transmission, or it can be established based on other more advanced mobile communication signals, or based on lower-level communication signals, such as 4G signals; in order to facilitate microwave communication and enhance the strength of the door, the other parts of the hollow part of the anti-theft door outside the micro base station are filled with microwave communication materials, such as ceramics. Due to the internal roads, greening and public activity spaces in the community, these public activity spaces are basically surrounded by unit buildings. Using the doors in the community as signal micro base stations is not only convenient to implement, but also can basically achieve full signal coverage of the community public space.

[0025] The microwave communication device performs wireless microwave communication with the micro base station, including an optical fiber microwave conversion device 21, which is deployed on the wall outside the weak current well of the unit building, and performs microwave communication with the micro base station. The optical fiber microwave conversion device 21 is connected to the laid optical fiber, and the optical fiber microwave conversion device is to realize the conversion of optical signals and electrical signals. Preferably, the optical fiber is introduced from the weak current well and connected to the optical fiber microwave conversion device 21. Of course, other communication propagation media can also be used, not limited to the optical fiber in this embodiment. Similarly, the optical fiber can be a 5G optical fiber, or other higher-level communication media or lower-level communication media; wherein, the micro base station has a microwave digital conversion device 11 for wireless communication with the optical fiber microwave conversion device 21, and the microwave digital conversion device 11 converts digital signals and electrical signals. The weak current well is generally close to the home anti-theft door or unit door, and there is usually a weak current well near the entrance door. In this way, the optical fiber microwave conversion device 21 installed at the weak current wellhead of each floor of the residents and the microwave digital conversion device 11 of the micro base station can be conveniently used for microwave communication transmission. In this embodiment, it is preferred that the optical fiber microwave conversion device 21 and the microwave digital conversion device 11 are set at the same height, with no obstruction between the two, to facilitate direct transmission of microwave signals. The optical fiber microwave conversion device 21 is installed on the wall outside the weak current well, and the microwave digital conversion device 11 is located inside the anti-theft door and is roughly flush with the outer side of the door surface of the anti-theft door. The use of microwave transmission technology can also avoid the problem of cable connection or optical fiber connection being broken due to the rotation of the door shaft.

[0026] Specifically, in this embodiment, the micro base station includes a micro base station main control device 12, a microwave panel 13 made of microwave communication materials (such as ceramics), the strength of the microwave panel 13 should reach the security level marked on the anti-theft door, the micro base station control device 12 and the microwave digital conversion device 11 are wired communication, using bidirectional wired transmission of digital signals, such as high-speed shielded network cables or dedicated cables, the microwave panel 13 is made into a sandwich structure, and a microwave antenna for communicating with the micro base station main control device 12 is arranged inside the sandwich, and the microwave antenna also communicates wirelessly with an external intelligent terminal, such as a mobile phone, and the frequency band range of the microwave antenna can be selected according to the coverage range of the micro base station. The microwave communication antenna is generally a reflector antenna with strong directivity, high efficiency, and high gain, such as a parabolic antenna, a Cassegrain antenna, etc. The feeder mainly uses a waveguide or a coaxial cable. In this embodiment, the micro base station main control device is connected to the microwave antenna through a 50Ω coaxial cable, and the feeder cable is short and the loss is small.

[0027] In this embodiment, the microwave antenna can be a TD-standard uplink and downlink multiplexing antenna, that is, the uplink antenna and the downlink antenna are essentially the same, wherein the TD-standard uplink and downlink multiplexing antenna is located in the center of the microwave panel 13 and is connected to the micro base station main control device 12 via a coaxial cable.

[0028] The microwave antenna can also be an FD-standard uplink and downlink separate antenna, wherein the uplink and downlink separate antennas are located in the center of the microwave panel 13, and are distributed left and right, with a spacing greater than 20 cm, to avoid the influence between the two antennas and the influence of the metal around the anti-theft door on the transmission signal. The two antennas are respectively connected to the micro base station main control device 12 through their own coaxial cables. Figure 1 14 is an uplink antenna, and 15 is a downlink antenna.

[0029] Since the micro base station of the present invention is arranged in the anti-theft door, it is convenient to obtain power. Optionally, the micro base station and the anti-theft door share the same DC power supply, such as 3V voltage, and the DC power supply of the required voltage level is realized through the DC / DC module of each device in the micro base station. Different components, such as the microwave digital conversion device and the main control device, may require different DC voltages, which can be converted into the required corresponding voltage through the DC / DC module. Optionally, the micro base station converts the external 220V mains power into DC power through the AC / DC converter, and realizes the DC power supply of the required voltage level through the DC / DC module of each device in the micro base station. In this mode, the micro base station does not share the same DC power supply with the anti-theft door. It connects the household 220V AC power through the power line in the door, and then converts it into DC power, and then provides the appropriate voltage to different components through the DC / DC module. Similarly, when the micro base station is set at the unit door or the community gate, it can directly obtain power. Since the unit door or the community gate is equipped with an anti-theft system, it can share the DC power supply with them. The AC / DC converter and the DC / DC module can both use the AC / DC converter or DC / DC converter commonly used in the prior art.

[0030] Reference Figure 2 As shown, in the embodiment of the present invention, taking 5G communication as an example, an example of the communication process between a mobile phone and a micro base station is described as follows:

[0031] The uplink signal of the mobile phone reaches the micro base station main control device 12 of the 5G signal through the uplink antenna 14, then reaches the microwave digital conversion device 11, then reaches the optical fiber microwave conversion device 11 through microwave transmission, and finally reaches the 5G optical fiber of the weak current well; the opposite process is that the downlink signal is sent to the optical fiber microwave conversion device 11 through the 5G optical fiber, reaches the microwave digital conversion device 21 through microwave transmission, then reaches the 5G signal micro base station main control device 12, and finally reaches the mobile phone through the downlink antenna 15. Among them, the microwave digital conversion device 11 and the micro base station main control device 12 in the anti-theft door can be powered by the DC power supply of the anti-theft door at the same time, and the DC power supply of the required voltage level can be realized through their respective DC / DC modules. When necessary, 220V AC can be converted into DC power with a safe voltage and supplied to the anti-theft door for use by their respective DC / DC, so as to avoid the problem of insufficient DC load capacity or too large ripple of the anti-theft door.

[0032] In this embodiment, the optical fiber microwave conversion device can be composed of a 10G optical module, such as Huawei's 10G multi-mode OMXD3000SFP+10G optical module, and a 10G wireless router (ASUS GT-AX11000 tri-band wireless 10G enterprise router), and the microwave digital conversion device can directly use a 10G wireless router (ASUS GT-AX11000 tri-band wireless 10G enterprise router). The micro base station master control device can use Huawei's micro base station equipment, such as Huawei AAU5270 base station control unit. The implementation method of microwaves of other frequencies on the building unit door is similar. As long as the transparent transmission bandwidth is sufficient (i.e., the transparent transmission bandwidth ≥ the actual terminal bandwidth required), it is only necessary to select or develop the corresponding micro base station master control device to release the desired micro base station signal.

[0033] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
