Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to an antenna engineering parameter acquisition and anomaly warning device. Background Art

[0002] In mobile communication engineering, the hanging height, azimuth angle, and downward tilt angle of base station antennas are key factors determining the coverage effect of base stations, and are directly related to the communication quality of the mobile communication network. In a mobile communication system, if there are deviations in the hanging height, azimuth angle, and downward tilt angle of a base station antenna, not only will the network service quality be reduced, but also the subsequent optimization effect will be affected. Under the traditional construction mode, only when there are major position changes in the antenna, resulting in interruptions in the circuit or optical path, will the back-end maintenance personnel be notified. Therefore, the back-end maintenance personnel cannot arrive at the scene in the first place to adjust the engineering parameters with transmission deviations.

[0003] In addition, whether the overall installation of the antenna is safe and reliable is also directly related to the life and property safety around the base station. If the installation situation of the antenna can be detected and the back-end maintenance personnel can be informed in a timely manner, not only can relevant potential safety hazards be eliminated in advance, but also greater economic losses can be prevented in a timely manner. Summary of the Invention

[0004] In view of the above problems, this application provides an antenna engineering parameter acquisition and anomaly warning device, which solves the problem that the overall installation situation of the antenna cannot be detected in a timely manner, and when an anomaly occurs in the antenna installation, maintenance cannot be carried out in a timely manner by the back-end maintenance personnel.

[0005] To achieve the above object, the inventor provides an antenna engineering parameter acquisition and anomaly warning device, including a housing, a central processing unit, a first angle sensor, a second angle sensor, a power supply module, a communication module, a connecting rod, a front roller, and a secondary roller;

[0006] The central processing unit, the communication module, and the power supply module are arranged on the housing;

[0007] The housing is provided with a mounting structure for mounting on a pole;

[0008] The connecting rod includes a primary connecting rod and a secondary connecting rod. One end of the primary connecting rod is connected to one end of the secondary connecting rod, and the other end of the primary connecting rod is mounted on the antenna mounting kit through a front roller;

[0009] The other end of the secondary connecting rod is connected to the housing through a secondary roller;

[0010] The rotation direction of the front roller is the vertical direction, and the rotation direction of the secondary roller is the horizontal direction;

[0011] The first angle sensor and the second angle sensor are connected to the central processor. The first angle sensor is used to detect the rotation angle of the front roller, and the second angle sensor is used to detect the rotation angle of the secondary roller;

[0012] The processor is used to calculate the downward tilt angle of the antenna according to the angle detected by the first angle sensor, calculate the azimuth angle of the antenna according to the angle detected by the second angle sensor, and calculate whether the installation angle of the antenna is abnormal according to the calculated downward tilt angle or azimuth angle. If it is abnormal, a warning signal is sent through the communication module;

[0013] The communication module is connected to the central processor;

[0014] The power supply module is connected to the central processor, the first angle sensor, the second angle sensor and the communication module.

[0015] For further optimization, it further includes a pressure acquisition rod and a gravity sensor;

[0016] The pressure acquisition rod is arranged on the housing, and the other end of the secondary connecting rod is arranged on the pressure acquisition rod through the secondary roller;

[0017] The gravity sensor is connected to the central processor, and the gravity sensor is used to detect the pressure change value on the pressure acquisition rod;

[0018] The central processor is used to judge whether the antenna installation kit is firmly installed according to the pressure change value on the pressure acquisition rod collected by the gravity sensor. If it is not firm, a warning signal is sent through the communication module.

[0019] For further optimization, the power supply module is a solar power supply module.

[0020] For further optimization, the communication module is a wireless communication module.

[0021] For further optimization, the communication module is a wired communication module, and the communication module is connected to the RRU module or the AAU module of the antenna.

[0022] For further optimization, a primary roller is further arranged between the primary connecting rod and the secondary connecting rod, and the rotation direction of the primary roller is vertical.

[0023] For further optimization, it further includes a positioning module, and the positioning module is connected to the central processor.

[0024] For further optimization, the positioning module is a GPS module.

[0025] Another technical solution is also provided: a method for collecting antenna engineering parameters and abnormal warning. The method is applied to the above-mentioned antenna engineering parameter collection and abnormal warning device, and the method includes the following steps:

[0026] The first angle sensor collects the angle change of the front roller, and the second angle sensor collects the angle change of the secondary roller;

[0027] The central processing unit calculates the downward tilt angle of the antenna according to the angle detected by the first angle sensor, and calculates the azimuth angle of the antenna according to the angle detected by the second angle sensor;

[0028] The central processing unit calculates whether the installation angle of the antenna is abnormal according to the calculated downward tilt angle or azimuth angle. If it is abnormal, a warning signal is sent through the communication module.

[0031] The central processing unit judges whether the antenna installation kit is firmly installed according to the pressure change value of the pressure collection rod collected by the gravity sensor. If it is not firm, a warning signal is sent through the communication module.

[0032] Different from the prior art, in the above technical solution, the antenna is installed on the pole by the installation kit. However, when monitoring the installation state of the antenna, the housing of the device is installed on the pole through the installation structure. The installation position of the housing is at the upper end of the antenna pole. Then, one end of the first connecting rod is installed on the installation kit of the antenna. When the downward tilt angle of the installation kit of the antenna changes, it will drive the angle of the front roller to change. And when the azimuth angle of the installation kit of the antenna changes, it will drive the angle of the secondary roller to change through the first connecting rod and the second connecting rod. The central processing unit can calculate the downward tilt angle of the antenna installation kit according to the change angle of the first roller collected by the first angle sensor, and calculate the azimuth angle of the antenna installation kit according to the change angle of the second optical axis collected by the second angle sensor. Then, the central processing unit judges whether the antenna has an abnormal installation according to the calculated downward tilt angle and azimuth angle of the antenna. If there is an abnormal installation, a warning message is sent to the maintenance background through the communication module, which can notify the maintenance personnel in time, so that the maintenance personnel can arrive at the scene to maintain the antenna in the first time, avoiding damage to the surrounding life and property safety due to abnormal antenna installation.

[0064] Please refer to Figure 1-4, this embodiment provides an antenna engineering parameter acquisition and anomaly warning device, including a housing 110, a central processing unit 120, a first angle sensor 131, a second angle sensor 132, a power supply module 140, a communication module 150, a connecting rod 160, a front roller 171, and a secondary roller 172;

[0065] The central processing unit 120, the communication module 150, and the power supply module 140 are arranged on the housing 110;

[0066] The housing 110 is provided with a mounting structure 111 for mounting on a pole 300;

[0067] The connecting rod 160 includes a primary connecting rod 161 and a secondary connecting rod 162. One end of the primary connecting rod 161 is connected to one end of the secondary connecting rod 162, and the other end of the primary connecting rod 161 is mounted on the mounting kit 210 of the antenna 200 through the front roller 171;

[0068] The other end of the secondary connecting rod 162 is connected to the housing 110 through the secondary roller 172;

[0069] The rotation direction of the front roller 171 is the vertical direction, and the rotation direction of the secondary roller 172 is the horizontal direction;

[0070] The first angle sensor 131 and the second angle sensor 132 are connected to the central processing unit 120. The first angle sensor 131 is used to detect the rotation angle of the front roller, and the second angle sensor 132 is used to detect the rotation angle of the secondary roller 172; The front roller 171 can only rotate up and down, which is used to collect the change of vertical torque. By connecting the first angle sensor 131 with the front roller 171, the angle change corresponding to the vertical torque is collected. The secondary roller 172 can only rotate left and right, which is used to collect the change of horizontal torque. The second angle sensor 132 is connected to the secondary roller 172, and then the horizontal angle change amount corresponding to the horizontal torque is collected.

[0071] The processor is used to calculate the downward tilt angle of the antenna 200 according to the angle detected by the first angle sensor 131, calculate the azimuth angle of the antenna 200 according to the angle detected by the second angle sensor 132, and calculate whether the installation angle of the antenna 200 is abnormal according to the calculated downward tilt angle or azimuth angle. If it is abnormal, a warning signal is sent through the communication module 150;

[0072] The communication module 150 is connected to the central processing unit 120; The communication module 150 sends these parameters collected by the first angle sensor 131 and the second angle sensor 132 to the background to realize real-time monitoring and warning.

[0073] The power supply module 140 is connected to the central processing unit 120, the first angle sensor 131, the second angle sensor 132, and the communication module 150.

[0074] The antenna 200 is installed on the pole 300 through the installation kit 210. When monitoring the installation state of the antenna 200, the housing 110 of the device is installed on the pole 300 through the installation structure 111. The installation position of the housing 110 is at the upper end of the antenna 200. Then, one end of the first-level connecting rod 161 is installed on the installation kit 210 of the antenna 200. When the downward inclination angle of the installation kit 210 of the antenna 200 changes, it will drive the angle of the front roller 171 to change. When the azimuth angle of the installation kit 210 of the antenna 200 changes, it will drive the angle of the second-level roller 172 to change through the first-level connecting rod 161 and the second-level connecting rod 162. The central processing unit 120 can calculate the downward inclination angle of the installation kit 210 of the antenna 200 according to the change angle of the front roller 171 collected by the first angle sensor 131, and calculate the azimuth angle of the installation kit 210 of the antenna 200 according to the change angle of the second-level optical axis collected by the second angle sensor 132. Then, the central processing unit 120 determines whether the antenna 200 has an abnormal installation according to the calculated downward inclination angle and azimuth angle of the installation kit 210 of the antenna 200. If there is an abnormal installation, a warning message is sent to the maintenance background through the communication module 150, which can notify the maintenance personnel in time, so that the maintenance personnel can arrive at the scene to maintain the antenna 200 immediately, avoiding damage to the surrounding life and property safety due to abnormal installation of the antenna 200.

[0075] This device can collect three engineering parameters of the hanging height, azimuth angle, and downward inclination angle of the antenna 200 and the safety status information of the antenna 200 in real time. When the parameters change or the safety status is abnormal, an alarm can be issued to notify the background maintenance personnel to adjust the change information on site in time, so as to ensure the accuracy and reliability of the base station parameters, facilitate subsequent optimization and adjustment, maximize the network coverage effect and communication quality, and also enable the background personnel to perceive the safety status of the antenna 200 in advance, timely eliminate potential safety hazards, and prevent unnecessary life and property losses around the base station. At the same time, the installation angle change of the antenna 200 is collected through the connecting rod 160, avoiding the problem of inaccurate angle measurement by traditional methods caused by electromagnetic interference.

[0076] The rotation angle of the front roller 171 is collected through the first angle sensor 131, and then the included angle θ of the installation kit 210 of the antenna 200 is collected. Then, the downward inclination angle β and its change amount Δ are calculated through certain steps. Specifically, please refer to Figure 5 the schematic diagram of the downward inclination angle calculation model shown in Figure 6Schematic diagram after equivalent processing of the downtilt angle calculation. Point A corresponds to the left vertex of the upper mounting kit 210 of the antenna 200, point B corresponds to the right vertex of the upper mounting kit 210, point E corresponds to the vertex at the middle folding of the upper mounting kit 210, point C corresponds to the vertex of the bottom mounting kit 210, and point D corresponds to the midpoint of side AB; where the left and right folding arm lengths of the upper mounting kit 210 are equal, i.e., AE = BE, A0, B0, C0, D0, E0 correspond to the positions of the antenna 200 before the installation position changes, and A1, B1, C1, D1, E1 correspond to the positions of the antenna 200 after the installation position changes. The downtilt angle β and its change difference Δ after the change can be calculated by the following steps:

[0077] Step 1: Assume the initial angles are θ0, β0, and the changed angles are θ1, β1. Then: ∠A0E0B = θ0; ∠A1E1B = θ1; ∠A0CB = β0; ∠A1CB = β1;

[0078] Step 2: Let A0C = A1C = h1, BC = h2; A0E0 = A1E1 = h3;

[0079] Step 3: It can be obtained that:

[0080] Step 4: It can be obtained that:

[0081] Step 5, then the change amount of the downtilt angle of the antenna 200 can be obtained as: Δ = β1 - β0.

[0082] When the change amount of the calculated downtilt angle obtained by the central processing unit 120 is greater than the preset change value, it is determined that the installation of the antenna 200 is abnormal.

[0083] Since the front roller 171 only has an angular change in the vertical direction and the secondary roller 172 only has an angular change in the horizontal direction, the angular change of the front roller 171 does not affect the horizontal angular change amount of the secondary roller 172. The initial azimuth angle of the antenna 200 installation is α0, and the second angle sensor 132 detects in real time that the horizontal angular change amount of the secondary roller 172 is δ. Then the azimuth angle α of the antenna 200 at this time is α = α0 + δ (the angular increment in the clockwise direction is positive, and the angular increment in the counterclockwise direction is negative). The central processing unit 120 can determine whether the installation of the antenna 200 is abnormal according to whether the azimuth angle of the antenna 200 at this time is greater than the preset azimuth angle.

[0084] In some embodiments, the first angle sensor 131 and the second angle sensor 132 can collect the changing angles of the front roller 171 or the secondary roller 172 in real time; in other embodiments, the central processor 120 can wake up the first angle sensor 131 and the second angle sensor 132 according to a preset time to collect the changing angles of the front roller 171 and the secondary roller 172. In some embodiments, the central processor 120 can first wake up the first angle sensor 131 and the second angle sensor 132 according to a preset time to collect the changing angles of the front roller 171 and the secondary roller 172. When the changing angles of the front roller 171 and the secondary roller 172 collected are greater than a first preset change value, the first angle sensor 131 and the second angle sensor 132 collect the changing angles of the front roller 171 or the secondary roller 172 in real time.

[0085] In some embodiments, a pressure collection rod 163 and a gravity sensor 180 are further included;

[0086] The pressure collection rod 163 is arranged on the housing 110, and the other end of the secondary connecting rod 162 is arranged on the pressure collection rod 163 through the secondary roller 172;

[0087] The gravity sensor 180 is connected to the central processor 120, and the gravity sensor 180 is used to detect the pressure change value on the pressure collection rod 163;

[0088] The central processor 120 is used to judge whether the mounting kit 210 of the antenna 200 is firmly installed according to the pressure change value on the pressure collection rod 163 collected by the gravity sensor 180. If it is not firmly installed, a warning signal is sent through the communication module 150.

[0089] After the antenna 200 is installed, the initial pressure value on the pressure collection rod 163 is N0, the real-time pressure change amount of the pressure collection rod 163 detected by the gravity sensor 180 is F, and the preset pressure threshold is set to M. After the device is installed, the central processor 120 judges in real time that the pressure value on the pressure collection rod 163 is N = N0 + F. If N > M, it means that there is a problem with the installation of the antenna 200 at this time, resulting in the mounting kit 210 not being firmly installed. The central processor 120 sends a warning signal through the communication module 150 to notify the background maintenance personnel to come to the station for repair, thereby reducing the possibility of life and property losses caused by potential safety hazards of the antenna 200. By converting the monitoring of the safety state of the installation of the antenna 200 into the monitoring of the gravity sensor value, the judgment of whether the antenna 200 is normally installed is realized, the safety state of the antenna 200 is perceived in advance, potential safety hazards are eliminated in time, and unnecessary life and property losses around the base station are reduced.

[0090] In some embodiments, the power supply module 140 is a solar power supply module. By covering the solar panels outside the housing 110, power is supplied to the device. Using solar power supply can achieve persistent power supply for the device and avoid the problem of difficult on-site maintenance caused by battery life in the later stage.

[0091] In some embodiments, the communication module 150 is a wireless communication module 150. Among them, the communication module 150 can utilize the sidelobe characteristics of the antenna 200 to realize wireless transmission of signals based on NB.

[0092] In some embodiments, the communication module 150 is a wired communication module, and the communication module 150 is connected to the RRU module or the AAU module of the antenna 200. The communication module 150 can also adopt a wired method to feed the signal into the background network management through the RRU (Remote Radio Unit) module or the AAU (Active Antenna Unit) module.

[0093] In some embodiments, the first-level roller 173 between the first-level connecting rod 161 and the second-level connecting rod 162, and the rotation direction of the first-level roller 173 is vertical. By arranging the first-level roller 173 between the first-level connecting rod 161 and the second-level connecting rod 162, the vertical torque of the first-level roller 173 is used for the adjustment during the installation of the device and the antenna. After the adjustment is completed, the first-level roller 173 will be fixed so that the first-level roller 173 will not affect the calculation of the antenna downtilt angle. During the installation of the device and the antenna, the angle between the first-level connecting rod 161 and the second-level connecting rod 162 can be adjusted through the first-level roller 173, so that the device and the antenna can be accurately connected. After the angle between the first-level connecting rod 161 and the second-level connecting rod 162 is adjusted, the first-level roller 173 is fixed so that the first-level roller 173 will not rotate due to external force.

[0094] In some embodiments, a positioning module 190 is further included, and the positioning module 190 is connected to the central processing unit 120. Among them, the positioning module 190 is a GPS module, and the GPS module is used to collect the position information of the base station to achieve high-precision positioning. In other embodiments, the positioning module 190 can also adopt a Beidou satellite module.

[0095] In another embodiment, a method for collecting antenna engineering parameters and abnormal alarm, the method is applied to the antenna engineering parameter collection and abnormal alarm device in the above embodiments, and the method includes the following steps:

[0096] The first angle sensor collects the angle change of the front roller and the second angle sensor collects the angle change of the second-level roller;

[0097] The central processing unit calculates the downtilt angle of the antenna based on the angle detected by the first angle sensor and calculates the azimuth angle of the antenna based on the angle detected by the second angle sensor;

[0098] The central processing unit calculates whether the installation angle of the antenna is abnormal based on the calculated downtilt angle or azimuth angle. If it is abnormal, a warning signal is sent through the communication module.

[0099] The antenna is installed on the mast through the installation kit. When monitoring the installation state of the antenna, the housing of the device is installed on the mast through the installation structure. The installation position of the housing is at the upper end of the antenna. Then one end of the first connecting rod is installed on the installation kit of the antenna. When the downtilt angle of the installation kit of the antenna changes, it will drive the change of the angle of the front roller. When the azimuth angle of the installation kit of the antenna changes, it will drive the change of the angle of the second roller through the first connecting rod and the second connecting rod. The central processing unit can calculate the downtilt angle of the antenna installation kit based on the change angle of the front roller collected by the first angle sensor and calculate the azimuth angle of the antenna installation kit based on the change angle of the second optical axis collected by the second angle sensor. Then the central processing unit judges whether the antenna has an abnormal installation based on the calculated downtilt angle and azimuth angle of the antenna installation kit. If there is an abnormal installation, a warning message is sent to the maintenance background through the communication module, which can notify the maintenance personnel in time, so that the maintenance personnel can arrive at the scene to maintain the antenna in the first time, avoiding damage to the surrounding life and property safety due to abnormal antenna installation.

[0100] In some embodiments, the following steps are further included:

[0101] The gravity sensor collects the pressure change value of the pressure collection rod;

[0102] The central processing unit judges whether the installation kit of the antenna is firmly installed based on the pressure change value collected by the gravity sensor on the pressure collection rod. If it is not firm, a warning signal is sent through the communication module.

[0103] After the antenna is installed, the initial pressure value on the pressure collection rod is N0, the real-time pressure change amount detected by the gravity sensor of the pressure collection rod is F, and the preset pressure threshold is set to M. After the device is installed, the central processing unit judges in real time that the pressure value on the pressure collection rod is N = N0 + F. If N > M, it means that there is a problem with the antenna installation at this time, resulting in the installation kit not being firmly installed.
