Description

Technical Field

[0001] The present invention relates to the technical field of communication auxiliary equipment, and in particular to a base station antenna engineering parameter measurement device and a network system. Background Art

[0002] As an important component of wireless communication, the selection and installation of base station antennas not only determine the network coverage, but also affect the quality and stability of the network. Base station antennas are usually installed outdoors, and their operational stability is easily affected by multiple factors, including damage from natural disasters such as typhoons, rainstorms and earthquakes, the limited service life of fasteners on the antenna, and human damage. The above factors will cause the antenna posture to change, affecting the stability of signal transmission, resulting in reduced network quality and user experience, which will have a negative impact on residents' production and life. Therefore, it is necessary to regularly measure the base station antenna parameters.

[0003] Base station antenna engineering parameters are parameters that describe and define antenna performance characteristics, including but not limited to downtilt angle, azimuth, longitude and latitude, and hanging height. The acquisition, recording, and monitoring of base station antenna engineering parameters are the basic work of network optimization. Generally, base station antenna engineering parameters are obtained by professionals with high-altitude work qualifications using handheld equipment to climb antenna poles or brackets to measure and record, and the data is uniformly entered into the system.

[0004] However, the measurement efficiency of base station antenna detection using manual handheld engineering parameter measurement equipment is low. Summary of the invention

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

The processing unit then processes and outputs the industrial parameter information of the measured signal, thereby eliminating the need for personnel to climb to the top of the base station antenna to measure the industrial parameters of the base station antenna, thereby improving the measurement efficiency of the industrial parameters of the base station antenna. Moreover, compared with the installation of the industrial parameters measurement equipment of the base station antenna on the top of the base station antenna, the installation convenience and measurement flexibility of the industrial parameters measurement equipment of the base station antenna can be improved by adjusting the position of the clamping assembly to clamp the outer cover of the base station antenna.

[0012] At the same time, the installation process of the industrial parameter measurement equipment is simplified, so that the installers do not need to climb to the top of the antenna to install the equipment, which improves the installation safety and efficiency of the industrial parameter measurement equipment. At the same time, it has strong compatibility and can adapt to most antennas in the existing network.

The two navigation and positioning antennas are used to receive the satellite signals so that the processing unit can determine the direction and position of the base station antenna by signal phase differential.

[0014] In a possible implementation, the connecting rod extends in a horizontal direction, and the distance between the navigation and positioning antenna and the adjacent side walls of the outer cover of the base station antenna is less than or equal to 0.6λ0-0.8λ0, where λ0 is the operating wavelength of the navigation and positioning antenna.

[0015] In a possible implementation, the clamping assembly includes at least two clamping plates, the first ends of the at least two clamping plates are fixed to the connecting rod, the at least two clamping plates are spaced apart on the connecting rod, and the plate surface direction of the clamping plates and the axial direction of the connecting rod have an angle so that a clamping space is formed between two adjacent clamping plates; when the base station antenna cover is in the clamping space, the two adjacent clamping plates are respectively clamped on opposite sides of the base station antenna cover.

[0016] In a possible implementation, the clamping plate includes a first side wall and a second side wall that are arranged opposite to each other, the first side wall faces the inner side of the clamping space, and the wall surface of the first side wall is a rough surface;

[0017] A reinforcing rib is formed on the second side wall.

[0018] In a possible implementation manner, the first side wall of the clamping plate is provided with an adhesive layer.

[0019] In a possible implementation, the base station antenna engineering parameter measurement equipment also includes a limit assembly arranged on the connecting rod, and the limit assembly is installed on the side of the clamping plate away from the clamping space and abuts against the clamping plate, so as to limit the movement of the clamping assembly in a direction close to the navigation positioning antenna.

[0039] As described in the background technology, the base station antennas installed outdoors often have unstable signals due to environmental factors. Workers need to regularly measure the engineering parameters of the base station antennas, which has the problem of low measurement efficiency. The inventors have found that the main reason for this problem is that at present, the acquisition of the engineering parameters of the base station antenna is done by professionals with high-altitude work qualifications climbing the antenna pole or bracket with handheld equipment to measure and record, and the data is uniformly entered into the system. However, this method has high labor costs, low safety, and low test efficiency and accuracy.

[0040] In addition, in the related art, the industrial parameter equipment of the base station antenna is installed on the top of the base station antenna. The installation method includes external installation, that is, the industrial parameter equipment is independently installed on the outside of the base station antenna; and also includes the base station antenna with built-in industrial parameter equipment at the factory, that is, the antenna and the industrial parameter equipment are integrated into one. The existing base station antennas in the existing network do not have built-in functions, so they can only use external industrial parameter equipment. New base station antennas can choose external industrial parameter equipment or factory built-in industrial parameters. However, the external industrial parameter equipment in the related art cannot match different antennas at the same time, that is, the matching degree of the connection structure between the external industrial parameter equipment and the base station antenna is low, and the compatibility is poor; and it is difficult to upgrade the network management that supports the RAE protocol, so the application of industrial parameter equipment in the related art is limited.

[0041] Moreover, in the related art method of installing the industrial parameter equipment on the top of the base station antenna, personnel are required to climb up the pole to the top of the antenna to operate the equipment, which is less safe and more difficult to operate.

[0042] In response to the above technical problems, an embodiment of the present invention provides a base station antenna industrial parameter measurement device, which installs the device on the back of the outer cover of the base station antenna through a clamping assembly arranged on a connecting rod, and utilizes the signal interaction between a navigation positioning antenna connected to the connecting rod and located on the side of the base station antenna and a satellite to measure the industrial parameters of the base station antenna, and then uses a processing unit to process and output the industrial parameter information of the measurement signal, so that there is no need for personnel to climb to the top of the base station antenna to measure the industrial parameters of the base station antenna, thereby improving the measurement efficiency of the industrial parameters of the base station antenna. Moreover, compared with the base station antenna industrial parameter measurement device being installed on the top of the base station antenna, the installation convenience and measurement flexibility of the base station antenna industrial parameter measurement device can be improved by adjusting the position of the base station antenna outer cover clamped by the clamping assembly.

[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions 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 making creative work belong to the scope of protection of the present invention.

[0044] Combination Figure 1 and Figure 2 An embodiment of the present invention provides a base station antenna engineering parameter measurement device 200, which is installed on the outer cover of the base station antenna. The base station antenna engineering parameter measurement device 200 includes a connecting rod 210, a processing unit, a clamping assembly and a navigation positioning antenna 250.

[0045] It can be understood that the base station antenna engineering parameters refer to the parameters used to describe the performance and characteristics of the antenna, providing basic information about the antenna, including radiation characteristics, gain, directivity, beam width, operating frequency range, impedance matching. Specifically, the base station antenna engineering parameters include but are not limited to downtilt angle, azimuth angle, longitude and latitude, and hanging height.

[0046] The processing unit, the navigation and positioning antenna 250 and the clamping assembly are all connected to the connecting rod 210. The clamping assembly is two clamping plates 230. The processing unit is arranged in a main control box located in the middle of the connecting rod 210. The connecting rod 210 is clamped on the back side of the outer cover of the base station antenna through the two clamping plates 230; the two navigation and positioning antennas 250 are arranged on the connecting rod 210 at intervals, and the navigation and positioning antenna 250 is located on one side of the back side of the outer cover of the base station antenna for receiving satellite signals. The base station antenna and the navigation and positioning antenna 250 are both connected to the processing unit signal, and the processing unit is used to determine the base station antenna working parameters of the base station antenna according to the satellite signal. Specifically, the processing unit can analyze and process the measured base station antenna working parameter data, including but not limited to calibrating, comparing and counting the data.

[0047] In this way, the equipment is installed on the back of the outer cover of the base station antenna by means of the clamping assembly arranged on the connecting rod 210, and the signal interaction between the navigation positioning antenna 250 connected to the connecting rod 210 and located on the side and the satellite is used to measure the industrial parameters of the base station antenna, and then the processing unit processes and outputs the industrial parameter information of the measured signal, so that there is no need for personnel to climb to the top of the base station antenna to measure the industrial parameters of the base station antenna, thereby improving the measurement efficiency of the industrial parameters of the base station antenna. Moreover, compared with the installation of the base station antenna industrial parameter measurement equipment on the top of the base station antenna, the installation convenience and measurement flexibility of the base station antenna industrial parameter measurement equipment can be improved by adjusting the position of the base station antenna outer cover clamped by the clamping assembly.

[0048] It should be noted that the process parameter measurement device provided by the embodiment of the present invention is Figure 5 As shown, the backhaul of the industrial parameters can be achieved through the base station equipment. Specifically, the industrial parameters are transmitted to the network management system through the base station equipment and the transmission network.

[0049] Both ends of the connecting rod 210 are provided with positioning holes and / or fixing holes for cooperating with bolts to fix the navigation positioning antenna 250 to the end of the connecting rod 210. Optionally, a waterproof structure is provided in the positioning hole and / or the fixing hole.

[0050] Continue to combine Figure 1 There are two navigation and positioning antennas 250, and the two navigation and positioning antennas 250 are respectively installed at both ends of the connecting rod 210. The navigation and positioning antenna 250 includes a radiating body, which is an antenna body arranged inside the outer cover of the navigation and positioning antenna 250. The outer cover of the navigation and positioning antenna 250 is a rectangular outer cover, and the rectangular outer cover shell is parallel to the rod body of the connecting rod 210. After the engineering parameter measurement equipment is installed on the base station antenna outer cover 100, the outer covers of the navigation and positioning antennas 250 located at both ends of the connecting rod 210 face upward and face the sky at the same angle, that is, the radiating body of the navigation and positioning antenna 250 in the outer cover faces the sky vertically along the length direction of the rod body of the antenna holding pole, thereby maximizing the radiation space of the antenna and the electromagnetic wave conduction range between the satellite.

[0051] In this way, satellite signals can be received by two navigation and positioning antennas 250 through signal phase differential method, so that the processing unit can determine the direction and position of the base station antenna. Optionally, the signal phase differential method is a carrier phase differential method, that is, the base station antenna is directionally measured and / or positioned using the carrier phase differential method, and the azimuth and longitude and latitude parameters are output. In this way, the carrier phase differential method, that is, dual GPS direction finding, is adopted. For example, the navigation module carried by the direction finding is the Beidou Satellite Navigation System (BDS), which can improve the measurement accuracy of the base station antenna and the ability to resist electromagnetic interference during measurement.

[0052] As a possible embodiment, along the length direction of the connecting rod 210, the installation height of the navigation and positioning antenna 250 is greater than the height at which the connecting rod 210 is installed on the base station antenna cover 100, that is, the connecting rod 210 is connected to the back side of the cover of the navigation and positioning antenna 250, that is, it is located on the radiation back side of the navigation and positioning antenna 250. In this way, the problem of metal interference in the forward radiation space of the navigation and positioning antenna 250 is avoided.

[0053] It should be noted that if Figure 2 and Figure 3 As shown, when the base station antenna engineering parameter measurement device 200 performs engineering parameter testing on the base station antenna, the two navigation positioning antennas 250 remain stationary and synchronously observe the same multiple satellites (at least four) to obtain sufficient satellite observation data for subsequent positioning calculations; a system of equations is formed by the two-difference equations of multiple satellites, that is, the distance difference (two-difference) between the navigation positioning antenna 250 and each satellite can be calculated through the received satellite signals, and then for multiple groups of satellite observation data, a system of equations can be formed, in which each equation represents a group of satellite two-differences. In this way, the system of equations can be used for positioning calculations of base station antennas; further, the solution of the system of equations is the vector direction of the two antennas, and then the horizontal direction angle of the base station antenna is determined by coordinate system transformation.

[0054] Based on the above embodiment, it can be improved by continuing to combine Figure 2 , the connecting rod 210 extends in the horizontal direction, and the distance between the adjacent side walls of the outer cover of the navigation and positioning antenna 250 and the base station antenna is 0.6λ0-0.8λ0, where λ0 is the working wavelength of the navigation and positioning antenna 250. It can be understood that the measurement accuracy of the carrier phase direction finding is related to the distance L between the navigation and positioning antennas 250 located at both ends of the connecting rod 210, that is, the larger L is, the larger the satellite viewing space and overlapping airspace of the two navigation and positioning antennas 250 are, and the higher the measurement accuracy of the azimuth is.

[0055] In this embodiment, through the specific distance between the adjacent side walls of the outer cover of the navigation and positioning antenna 250 and the base station antenna, the ultra-large satellite viewing angle space and overlapping airspace of the navigation and positioning antenna 250 are realized. By having the ultra-large satellite viewing angle space, the navigation and positioning antenna 250 can receive more satellite signals, thereby providing more optional positioning sources and enhancing the availability of positioning; and the overlapping airspace provides overlapping verification of multiple satellite signals, reduces the uncertainty of a single satellite signal, and improves the accuracy of positioning. The two work together to improve the measurement speed and accuracy of base station antenna positioning and direction finding.

[0056] Combined with the accuracy comparison of commonly used engineering parameter information in Table 1, it can be seen that the engineering parameter measurement information output by the embodiment of the present invention is superior to the related technologies in terms of azimuth, inclination and positioning accuracy. The related technologies include but are not limited to manual handheld device measurement and engineering parameter device measurement set on the top of the antenna.

[0057] Table 1 Comparison of process parameter accuracy

[0058] Indicators / Accuracy Related technologies Embodiments of the present invention Azimuth 5° or 2° ±1° inclination ±1° ±0.1° Positioning accuracy 10 meters, or 5 meters ±1m

[0059] The connecting rod 210 is an integrally formed rod extending from one side of the outer cover of the base station antenna to the other side. Optionally, the connecting rod 210 is a steel pipe fitting with a high bearing capacity. Furthermore, the steel used for the steel pipe fitting is 304 stainless steel or 316L stainless steel to enhance its corrosion resistance to resist the rainy and humid environment in which the base station antenna is located.

[0060] As an example, the material used for the connecting rod 210 is non-metal, such as carbon fiber reinforced composite material, which ensures the strength of the connecting rod 210 while being lighter than pure metal material.

[0061] Optionally, the connecting rod 210 is a slender tube, whose length is the sum of the width W of the back of the antenna cover and the distance from the navigation positioning antenna to the base station antenna cover. The connecting rod 210 is provided with a wire hole on the axial or radial surface for accommodating the signal transmission line.

[0062] As an example, a waterproof structure is provided around the wire passing hole to prevent moisture from penetrating into the interior of the connecting rod 210 and affecting the stability of the line. Exemplarily, the waterproof structure is a silicone sealing layer filling the circumferential gap between the wire passing hole and the line, or it can be a waterproof sleeve nested in the wire passing hole, or a sealing tape circumferentially attached to the inner wall of the wire passing hole.

[0063] Since the width dimension W of the existing base station antenna cover 100 is approximately 140mm-550mm, in some examples, the length L of the connecting rod 210 is 400mm-800mm, for example, the length L of the connecting rod 210 is 400mm or 600mm or 800mm. Compared with the method in the related art where the base station antenna engineering parameter test equipment is installed on the top of the base station antenna cover 100, it not only avoids the problem that the front satellite viewing angle space is easily blocked by the base station antenna installed in the upper space, but also optimizes the size compatibility with the base station antenna while improving the test accuracy of the antenna azimuth.

[0064] In some possible embodiments, the radiating body of the navigation and positioning antenna 250 adopts a low-profile antenna of 5-15mm. For example, the radiating body of the navigation and positioning antenna 250 is 5mm or 10mm or 15mm. Furthermore, the low-profile antenna is a ceramic antenna or an air patch antenna. The navigation and positioning antenna 250 used for measurement is small and lightweight to reduce the overall volume and mass of the industrial parameter measurement equipment. Exemplarily, the ceramic antenna has a caliber of 30-50mm×30-50mm, and the air patch antenna has a caliber of 40-60mm×40-60mm. For example, the ceramic antenna has a caliber of 40mm×40mm, and the air patch antenna has a caliber of 55mm×55mm.

[0065] The processing unit is arranged in the main control box 220, and the main control box 220 is installed in the middle of the connecting rod 210, and can be installed at the midpoint of the connecting rod 210. The main control box 220 is also provided with an integrated circuit board and a battery module. The integrated circuit board is provided with a power supply module, a processing unit and a low-power communication module for transmitting the working parameter data of the base station antenna. The processing unit includes a data acquisition processing component and a main control unit.

[0066] The battery module is connected to the power module in the integrated circuit board by plugging and unplugging the power cord, thereby powering the integrated circuit board; the battery-powered wake-up mode has multiple ways, including timed wake-up, event-triggered wake-up, low-power standby, energy-saving mode and / or adaptive wake-up, which can significantly extend the service life of the integrated circuit board, thereby meeting the outdoor use requirements of at least 10 years.

[0067] As another example, the battery module can be replaced by an AISG (Antenna Interface Standards Group) interface for power supply. The main control box 220 is provided with an AISG (Antenna Interface Standards Group) interface, which is connected to the AISG interface of the remote radio frequency unit RRU, the antenna radio frequency integrated unit AAU (Active Antenna Unit) or the base station antenna through a control line, thereby realizing AISG interface power supply and data transmission and processing.

[0068] In another example, the batteries in the battery module are replaced with rechargeable batteries, and a voltage stabilizing circuit module is added to the main control box 220 to achieve solar power supply, energy saving and environmental protection.

[0069] In some embodiments, a barometer module and a gyroscope module are also electrically connected to the integrated circuit board. The barometer module is used to measure the air pressure value and output the altitude parameter; the gyroscope module is used to output the mechanical tilt angle parameter. By way of example, the accuracy of the mechanical tilt angle parameter in this embodiment is ±0.1° and the resolution is 0.01°.

[0070] It should be noted that when the base station antenna engineering parameter measurement equipment 200 is first installed on the base station antenna cover 100, it is quickly and accurately positioned through the continuously operating reference station (Continuously Operating Reference Stations, abbreviated as CORS). After that, it works in the base station environment and uses dual antenna positioning to output longitude and latitude parameters.

[0071] In another example, the integrated circuit board in the main control box 220 is also provided with sensors such as temperature, humidity and / or wind speed, so as to obtain more information about the environment in which the base station antenna is located.

[0072] As a possible embodiment, a camera is provided on the connecting rod 210, and a rotating module is installed between the camera and the connecting rod 210 to realize a multi-angle environment camera function.

[0073] In a possible implementation, Figure 1 As shown in the example, the clamping assembly includes two clamping plates 230, the first ends of the two clamping plates 230 are fixed to the connecting rod 210, and then combined with Figure 2 and Figure 3 The first end of the clamping plate 230 is the end close to the back of the base station antenna cover 100. For example, the first end of the clamping plate 230 is provided with a mounting through hole, and the clamping plate 230 is sleeved on the connecting rod 210 through the mounting through hole. Furthermore, the mounting through hole is a threaded hole, and the outer periphery of the connecting rod 210 is processed with an external thread. The first end of the clamping plate 230 is threadedly connected to the connecting rod 210 to improve the clamping stability of the clamping plate 230.

[0074] The two clamping plates 230 are arranged at intervals on the connecting rod 210 and are symmetrically distributed relative to the main control box 220, and the plate surface direction of the clamping plates 230 and the axial direction of the connecting rod 210 have an angle, and the angle is adapted to the shell shape of the base station antenna cover 100 to be clamped. For example, the base station antenna cover 100 is a parallelepiped and the angle is a right angle; in this way, a clamping space 240 is formed between two adjacent clamping plates 230; when the base station antenna cover 100 is in the clamping space 240, the two adjacent clamping plates 230 are respectively clamped on opposite sides of the base station antenna cover 100.

[0075] With such a structural design, the industrial parameter measurement device is installed on the back of the base station antenna cover 100 by using a clamping assembly. Figure 3 and Figure 4 As shown, the installer does not need to climb to the top of the base station antenna, and the antenna can be flexibly installed as there is space on the back of the antenna cover.

[0076] On the basis of the above embodiment, it can be improved that the clamping plate 230 includes a first side wall 231 and a second side wall 232 that are relatively arranged, the first side wall 231 faces the inner side of the clamping space 240, that is, the side facing the main control box 220, and the wall surface of the first side wall 231 is a rough surface, that is, the wall surface of the first side wall 231 is roughened in advance to increase the friction between the clamping plate 230 and the surface of the base station antenna cover 100, so as to facilitate the initial installation and positioning of the industrial parameter measurement equipment; exemplarily, the wall surface roughness Rz of the first side wall 231 is 1 mm to match the surface roughness state of different base station antenna covers 100, thereby improving the application range of the clamping plate 230.

[0077] Further, a reinforcing rib is formed on the second side wall 232, that is, on the second end of the clamping plate 230 opposite to the first end, the second side wall 232 is oblique to the first side wall 231, and the second side wall 232 is oblique to the first side wall 231. Figure 3 , thereby forming a rib plate structure on the non-contact side of the clamping plate 230 and the antenna, which stabilizes the structure and facilitates the initial installation and fixation of the industrial parameter measurement equipment.

[0078] As a possible embodiment, the first side wall 231 of the splint 230 is provided with an adhesive layer. Exemplarily, a plurality of dispersed glue positions or a single sheet-like glue position are provided on the surface of the first side wall 231 of the splint 230, and the glue positions are used to set the glue layer, wherein the glue layer can be block-shaped and dispersed and spaced on the surface of the first side wall 231 facing the clamping space 240. As an example, the glue used for the glue layer is a strong quick-drying fixing glue, thereby improving the connection strength between the splint 230 and the side wall of the base station antenna cover 100.

[0079] In some embodiments, the base station antenna industrial parameter measurement equipment 200 also includes a limit assembly arranged on the connecting rod 210, and the limit assembly is installed on the side of the clamping plate 230 away from the clamping space 240, and is against the clamping plate 230, and is used to limit the movement of the clamping assembly in the direction close to the navigation positioning antenna 250. Exemplarily, the limit assembly can be a limit block 260 or a limit sleeve distributed on the side of the clamping plate 230 away from the main control box 220.

[0080] Another example, combined with Figure 1The limit assembly includes two limit blocks 260 installed on the connecting rod 210. The two limit blocks 260 are respectively located on the side of the clamping plate 230 away from the clamping space 240 and are against the clamping plate 230. The clamping plate 230 and the limit blocks 260 are respectively provided with a first threaded hole and a second threaded hole along the axial direction of the connecting rod 210. In this way, the clamping force of the clamping plate 230 can be adjusted by bolts passing through the first threaded hole and the second threaded hole in sequence, so as to further fine-tune the clamping plate 230 after the base station antenna industrial parameter measurement equipment 200 is fixed on the base station antenna cover 100, thereby enhancing the installation strength of the industrial parameter measurement equipment.

[0081] Optionally, the two limit blocks 260 are replaced by two locking sleeves, which are sleeve-shaped and mounted on the connecting rod 210 by bolts, so as to improve the clamping stability of the clamping assembly on the antenna cover.

[0082] On the other hand, an embodiment of the present invention provides a network system, including the base station antenna engineering parameter measurement device provided by any of the above solutions.

[0083] The embodiments of the present invention can achieve the following beneficial effects:

[0084] The device is installed on the back of the outer cover of the base station antenna by means of a clamping assembly arranged on the connecting rod, and the signal interaction between the navigation positioning antenna connected to the connecting rod and located on the side of the base station antenna and the satellite is used to measure the industrial parameters of the base station antenna. The processing unit then processes and outputs the industrial parameter information of the measured signal, thereby eliminating the need for personnel to climb to the top of the base station antenna to measure the industrial parameters of the base station antenna, thereby improving the measurement efficiency of the industrial parameters of the base station antenna. Moreover, compared with the installation of the industrial parameters measurement equipment of the base station antenna on the top of the base station antenna, the installation convenience and measurement flexibility of the industrial parameters measurement equipment of the base station antenna can be improved by adjusting the position of the clamping assembly to clamp the outer cover of the base station antenna.

[0085] At the same time, the installation process of the industrial parameter measurement equipment is simplified, so that the installers do not need to climb to the top of the antenna to install the equipment, which improves the installation safety and efficiency of the industrial parameter measurement equipment. At the same time, it has strong compatibility and can adapt to most antennas in the existing network.

[0086] Combining the equipment and system provided by the two aspects of the present invention, after the equipment is quickly installed on the existing network antenna, remote monitoring of the base station antenna working parameters can be achieved, reducing the manpower and material resources for base station maintenance, providing accurate basic data for network optimization, reducing the base station resource inventory cycle and improving resource management efficiency.
