Background Art

[0002] Conventionally, in order to optimize a network of mobile communication base stations, a signal measuring device is moved within the network using a vehicle to measure the signal quality. In this case, the vertical and / or horizontal angle adjustment values ​​of the antenna are manually inputted according to the signal quality measured by the signal measuring device to adjust the angle of the antenna, thereby achieving network optimization.

[0003] However, according to the prior art, there is the inconvenience of having to input the calculated vertical and / or horizontal angle adjustment values ​​one by one and manually adjust the angle of the antenna. In order to measure the signal, the vehicle needs to be moved and measured each time. Therefore, a considerable amount of time is required to adjust the signal quality. Moreover, it is difficult to measure the signal quality without moving the vehicle. Summary of the invention

[0040] Figure 1 FIG. 2 is a diagram showing a system configuration of an apparatus to which the present invention is applied. Figure 2 This is a diagram showing an example of a configuration of an electronic terminal in a system to which an antenna signal quality control device according to an embodiment of the present invention is applied. Figure 3 A perspective view showing a clamping device arranged in such a way that the antenna can be tilted and rotated in the vertical direction and in the left and right directions. Figure 4 and Figure 5 To show that based on Figure 3 A diagram showing the tilting rotation state and the rotational rotation state of the antenna of the clamping device.

[0041] Reference Figure 1 The system may include: an antenna 1; a clamping device 10, used to adjust the rotation angle of the antenna 1 in the left-right direction and / or the up-down direction; a plurality of terminal devices 20, used to measure the signal quality of the antenna 1 at a specified position in the network; and a signal quality control device 100, which determines the rotation of the antenna 1 according to the signal quality measured by the terminal device 20 and sends it to the clamping device 10.

[0042] The antenna 1 may include a transmission antenna module (not shown) for transmitting a predetermined signal to an external communication device and a reception antenna module (not shown) for receiving a signal transmitted from the external communication device.

[0043] As an example, the transmitting antenna module may transmit a quality measurement data request signal to a terminal device 20 disposed at a predetermined position in the network, and the receiving antenna module may receive the quality measurement data transmitted from the corresponding terminal device 20. In this case, the receiving antenna module may sequentially receive quality measurement data from a plurality of terminals disposed in the network.

[0044] According to the implementation, a plurality of antennas 1 may be provided.

[0045] The clamping device 10 may include: a tilting unit 11, which is combined in a manner that the antenna 1 can be tilted and rotated in the up-down direction; and a rotating unit 12, which is combined in a manner that the antenna 1 can be rotated in the left-right direction. The tilting unit 11 and / or the rotating unit 12 may be directly combined with a pole (not shown) for setting the antenna 1, or may be combined with other units (e.g., Figure 3 The coupling unit shown in the figure 13) is indirectly coupled.

[0046] If the clamping device 10 receives the rotation angle adjustment value related to the left-right direction from the signal quality control device 100 , the clamping device 10 can drive the rotating unit 12 to tilt and rotate the antenna 1 in the left-right direction by a predetermined angle.

[0047] Furthermore, if the rotation angle adjustment value related to the up-down direction is received from the signal quality control device 100 , the clamping device 10 may drive the tilting unit 11 to tilt and rotate the antenna 1 by a predetermined angle in the up-down direction.

[0048] The plurality of terminal devices 20 are devices that measure the signal quality of the antenna 1 and provide the measured quality measurement data, and may be devices at a fixed position or devices at a movable position.

[0049] For example, among the plurality of terminal devices 20, the first terminal 21, the second terminal 22, the third terminal 23 and the fourth terminal 24 may be configured at different locations within the network. Figure 2 .

[0050] like Figure 2 As shown, the quality of the signal transmitted and received from the antenna 1 is measured at the respective positions of the first terminal 21, the second terminal 22, the third terminal 23, and the fourth terminal 24. In this case, in the case of a request from the signal quality control device 100, the first terminal 21, the second terminal 22, the third terminal 23, and the fourth terminal 24 measure the signal quality of the antenna 1 and send the quality measurement data to the signal quality control device 100.

[0051] The plurality of terminal devices 20 may be electronic terminals having a communication function.

[0052] As an example, the electronic terminal may be in the form of a mobile phone, a tablet personal computer, a desktop PC, a laptop PC, a netbook computer, a personal digital assistant (PDA) and a portable multimedia player (PMP).

[0053] On the other hand, the terminal device 20 may be embodied in the form of a drone or may be installed in a drone. In this case, the terminal device 20 may be formed as a single device. The terminal device 20 may use the characteristics of the drone to move and measure the signal quality of the antenna 1 at the target location.

[0054] The signal quality control device 100 requests quality measurement data from one of a plurality of terminal devices 20 arranged at a specified position within the network, determines a rotation angle adjustment value related to the left-right direction and / or the up-down direction of the antenna 1 based on the quality measurement data received from the corresponding terminal device 20, and sends an adjustment signal including the determined rotation angle adjustment value to the clamping device 10.

[0055] After the signal quality control device 100 sends an adjustment signal to the clamping device 10, it can request quality measurement data from the next terminal device 20 in the multiple terminal devices 20. Similarly, based on the quality measurement data received from the corresponding terminal device 20, it determines the rotation angle adjustment value related to the left-right rotation and / or the up-down tilt of the antenna 1, and sends an adjustment signal including the determined rotation angle adjustment value to the clamping device 10.

[0056] As described above, the signal quality control device 100 may use the signal quality data sequentially received from the plurality of terminal devices 20 to sequentially determine the rotation angle adjustment values ​​related to the left-right direction and / or the up-down direction of the antenna 1 .

[0057] Therefore, the clamping device 10 sequentially adjusts the rotation angle of the antenna 1 in the left-right direction and / or the up-down direction.

[0058] In more detail, Figure 3 As shown, after sending a request signal for quality measurement data to the terminal device 20 through the sending antenna module, the clamping device 10 can measure the current signal quality of the working measurement antenna 1 by receiving the quality measurement data transmitted from the corresponding terminal device 20 through the receiving antenna module, and based on the above-mentioned rotation angle adjustment value determined by the signal quality control device 100, use the rotating unit 12 to rotate the antenna 1 in the left and right direction, or tilt it in the up and down direction.

[0059] Although not shown, the clamping device 10 may include a tilting motor that provides a tilting driving force for the tilting unit 11 by electric driving, and a rotating motor that provides a rotating driving force for the rotating unit 12 by electric driving. The tilting motor and the rotating motor may receive power through a separate power supply unit provided outside the clamping device 10.

[0060] In the structure of the signal quality control device 100, if the tilt rotation angle adjustment value of the clamping device 10 is received from the control unit 110 described later, Figure 3 and Figure 4 As shown, with the tilt rotation point T1 of the tilt unit 11 as the center, the tilt unit 11 can be tilted and rotated in the up and down directions to adjust the directivity of the antenna 1.

[0061] Meanwhile, in the structure of the signal quality control device 100, if the rotation angle adjustment value of the clamping device 10 is received from the control unit 110 described later, Figure 3 and Figure 5 As shown, with the rotation point L1 of the rotating unit 12 as the center, the rotating unit 12 can rotate in the left and right direction and adjust the directivity of the antenna 1.

[0062] The signal quality control device 100 of the present invention may be a device separated from the clamping device 10 , and may be communicatively connected via a separate communication connection unit.

[0063] On the other hand, the signal quality control device 100 may also be formed inside the clamping device 10 .

[0064] Refer to the following Figure 6 The following embodiments describe in detail the specific structure and operation of the signal quality control device 100 .

[0065] Figure 6 FIG. 2 is a diagram showing the structure of a signal quality control device according to an embodiment of the present invention. Figure 6 The signal quality control device 100 may include a control unit 110, a communication unit 120, a storage unit 130, a signal quality calculation unit 140, and a rotation determination unit 150. The control unit 110, the signal quality calculation unit 140, and / or the rotation determination unit 150 of the signal quality control device 100 of this embodiment may be embodied as at least one processor.

[0066] First, the control unit 110 may process signals transmitted between various components of the signal quality control device 100 .

[0067] The communication unit 120 may include a first communication module that supports a communication interface with a plurality of terminal devices 20 that are respectively arranged at predetermined locations within the network.

[0068] As an example, the first communication module may include a module for wireless network connection or short range communication (Short Range Communication).

[0069] Among them, the wireless network technology is wireless local area network (Wireless LAN, WLAN), wireless broadband (Wireless Broadband, Wibro), wireless fidelity (Wi-Fi) and / or World Interoperability for Microwave Access (World Interoperability for Microwave Access, Wimax), etc. In addition, the short-range communication technology may include Bluetooth (Bluetooth), ZigBee (ZigBee), Ultra-Wideband (UWB, Ultra-Wideband), Radio Frequency Identification (RFID, Radio Frequency Identification) and / or Infrared Data Association (Infrared Data Association, IrDA), etc.

[0070] On the other hand, the communication unit 120 may further include a second communication module supporting a communication interface with the clamping device 10. The second communication module may support a wired or wireless communication technology.

[0071] The storage unit 130 may store data and / or algorithms etc. required for the signal quality control device 100 to operate.

[0072] As an example, the storage unit 130 may store an instruction and / or algorithm for calculating a signal quality measurement value based on data received from an Nth terminal device 20 among the plurality of terminal devices 20. In addition, the storage unit 130 may also store an instruction and / or algorithm for determining a rotation direction and angle of the antenna 1 based on the signal quality of the antenna 1 calculated previously.

[0073] Among them, the storage unit 130 may include storage media such as random access memory (Random Access Memory, RAM), static random access memory (SRAM), read-only memory (Read-Only Memory, ROM), programmable read-only memory (PROM) and / or electrically erasable programmable read-only memory (EEPROM).

[0074] The control unit 110 may request the signal quality measurement data from one of the plurality of terminal devices 20 arranged in the network through the communication unit 120 .

[0075] As an example, multiple terminal devices 20 configured in the network include a first terminal 21, a second terminal 22, a third terminal 23 and a fourth terminal 24. When it is assumed that the first terminal to the fourth terminal 24 are respectively configured at different positions in the network, the control unit 110 can request signal quality measurement data from the first terminal 21 of the first order.

[0076] In this case, if the signal quality measurement of the antenna 1 is completed based on the signal quality measurement data received from the first terminal 21 , that is, based on the first data, the control unit 110 may request the signal quality measurement data from the second terminal 22 in the next order.

[0077] Furthermore, if the signal quality measurement of the antenna 1 is completed based on the signal quality measurement data received from the second terminal 22 , that is, based on the second data, the control unit 110 may request the signal quality measurement data from the third terminal 23 in the next order.

[0078] Similarly, if the signal quality measurement of the antenna 1 is completed based on the signal quality measurement data received from the third terminal 23 , that is, based on the third data, the control unit 110 may request the signal quality measurement data from the fourth terminal 24 in the next order.

[0079] If the signal quality measurement of the antenna 1 is completed based on the signal quality measurement data received from the fourth terminal 24, that is, the fourth data, and the measured signal quality of the antenna 1 meets the target value, the control unit 110 can end the relevant work.

[0080] On the other hand, if the signal quality of the antenna 1 measured based on the fourth data does not satisfy the target value, the control unit 110 may re-request the signal quality measurement data from the first terminal 21 to the fourth terminal 24 in sequence.

[0081] The signal quality calculation unit 140 calculates the signal quality of the antenna 1 based on the signal quality measurement data received from the plurality of terminal devices 20 arranged in the network. In this case, if the signal quality measurement data is received from one of the plurality of terminal devices 20, the signal quality calculation unit 140 calculates the signal quality of the antenna 1 based on the signal quality measurement data received from the corresponding terminal device 20.

[0082] The signal quality calculation unit 140 may store the calculated signal quality measurement value in the storage unit 130 , or transmit the calculated signal quality measurement value to the rotation determination unit 150 and / or the control unit 110 .

[0083] Thereafter, when receiving the signal quality measurement data from the next terminal device 20 , the signal quality calculation unit 140 can calculate the signal quality of the antenna 1 based on the received signal quality measurement data.

[0084] The signal quality calculation unit 140 may also obtain the signal quality measurement value using an algorithm for calculating the signal quality measurement value based on the signal quality measurement data received from the terminal device 20 .

[0085] In this case, the algorithm for calculating the signal quality measurement value may be a least mean square (LMS) algorithm, a recursive least square (RLS) algorithm, or the like. Depending on the embodiment, an algorithm with a small error may be used.

[0086] As an example, the recursive least squares algorithm can calculate the noise power of the transmitted signal before and after noise filtering to calculate the signal quality target value. In addition, the recursive least squares algorithm can calculate the signal quality measurement value at the corresponding position by calculating the noise power of the received signal including the signal quality measurement data before and after noise filtering.

[0087] The algorithm for measuring the signal quality of the received signal is a common technique, and therefore, a detailed description thereof will be omitted.

[0088] The rotation determination unit 150 may compare the signal quality target value QR based on the transmission signal of the antenna 1 with the signal quality measurement value QN calculated by the signal quality calculation unit 140 , and determine the rotation direction and angle of the antenna 1 based on the difference QR−QN.

[0089] If the difference QR-Q1 between the signal quality target value QR and the signal quality measurement value Q1 is 0, the rotation determination unit 150 can determine that the signal quality of the antenna 1 meets the target value, and thus can determine not to rotate the antenna 1. Furthermore, if the difference QR-Q1 between the signal quality target value QR and the signal quality measurement value Q1 is not 0 but is within the error range, the rotation determination unit 150 determines that the signal quality of the antenna 1 meets the target value, and thus can determine not to rotate the antenna 1.

[0090] On the other hand, if the difference QR-Q1 between the signal quality target value QR and the signal quality measurement value Q1 is not 0 or exceeds the error range, the rotation determination unit 150 determines that the signal quality of the antenna 1 does not meet the target value, and thus can determine to rotate the antenna 1 in the left direction or the right direction. In this case, the rotation determination unit 150 can determine different rotation directions according to whether the difference QR-Q1 is a positive (+) value or a negative (-) value.

[0091] The rotation determining unit 150 may determine the rotation angle to be a predetermined angle. Alternatively, the rotation determining unit 150 may determine different rotation angles according to the size of the difference QR-Q1.

[0092] If the rotation direction and angle of the antenna 1 are determined by the rotation determination unit 150 , the control unit 110 sends a first adjustment signal including the rotation direction and angle information of the antenna 1 to the clamping device 10 connected to the communication unit 120 .

[0093] Therefore, the clamp device 10 can rotate the antenna 1 by a predetermined angle in the left-right direction based on the first adjustment signal received through the communication unit 120 .

[0094] On the other hand, if the signal quality measurement value Q2 calculated based on the second measurement data is transmitted from the signal quality calculation unit 140 after the rotation direction and angle of the antenna 1 are determined from the signal quality measurement value Q1 calculated based on the first measurement data, the rotation determination unit 150 can compare the signal quality target value QR of the transmission signal based on the antenna 1 with the signal quality measurement value Q2, and determine the rotation direction and angle based on the difference QR-Q2.

[0095] In this case, if the difference QR-Q2 is 0 or within the error range, the rotation determination unit 150 may determine that the signal quality of the antenna 1 meets the target value, and thus may determine not to rotate the antenna 1.

[0096] On the contrary, if the difference QR-Q2 is not 0 or exceeds the error range, the rotation determination unit 150 may determine that the signal quality of the antenna 1 does not meet the target value, and thus may determine to rotate the antenna 1 in the left direction or the right direction. In this case, if the difference QR-Q2 is less than the difference QR-Q1 calculated previously, the rotation determination unit 150 may determine the direction to be the same as the previous rotation direction, otherwise, it may determine the direction to be different from the previous rotation direction.

[0097] The rotation determining unit 150 may determine the rotation angle as a predetermined angle. Alternatively, the rotation determining unit 150 may determine different rotation angles according to the size of the difference.

[0098] If the rotation direction and angle of the antenna 1 are determined by the rotation determination unit 150 , the control unit 110 sends a second adjustment signal including the rotation direction and angle information of the antenna 1 to the clamping device 10 connected to the communication unit 120 .

[0099] Therefore, the clamp device 10 can rotate the antenna 1 whose angle has been adjusted previously again in the left-right direction by a predetermined angle based on the second adjustment signal received through the communication unit 120 .

[0100] In the above manner, the control unit 110 can sequentially send the third adjustment signal and the fourth adjustment signal to the clamping device 10. Furthermore, the clamping device 10 can rotate the antenna 1 in the left-right direction by a predetermined angle according to the received third adjustment signal and the fourth adjustment signal.

[0101] On the other hand, if the signal quality measurement value Q1 calculated based on the first measurement data is retransmitted after the antenna 1 is rotated in the left-right direction, the rotation determination unit 150 can compare the signal quality target value QR based on the transmitted signal of the antenna 1 with the signal quality measurement value Q1, and determine the rotation direction and angle of the antenna 1 according to the difference QR-Q1.

[0102] In this case, the rotation determination unit 150 can determine the rotation direction and angle in the above-mentioned manner, and the antenna 1 is in a state of being rotated in the left-right direction through the previous process, so the rotation direction of the antenna 1 can be determined as the up-down direction.

[0103] Therefore, the control unit 110 can sequentially send the first adjustment signal, the second adjustment signal, the third adjustment signal, and the fourth adjustment signal to the clamping device 10 based on the up-down direction.

[0104] The clamping device 10 can rotate the antenna 1 by a specified angle in the up-down direction according to the received first adjustment signal, second adjustment signal, third adjustment signal, and fourth adjustment signal.

[0105] In this regard, if the signal quality of the antenna 1 measured by the vertical rotation of the antenna 1 satisfies the target value, the control unit 110 may end the relevant operation.

[0106] On the other hand, if the signal quality of the antenna 1 measured by the vertical rotation of the antenna 1 does not satisfy the target value, the control unit 110 may re-request the signal quality measurement data from the first terminal 21 to the fourth terminal 24 in sequence.

[0107] The signal quality control device 100 of the present embodiment working as described above may be implemented as an independent hardware device, as at least one processor, and may be driven in the form of other hardware devices such as a microprocessor or a common computer system.

[0108] The processor may be a semiconductor device that processes a plurality of instructions stored in a central processing unit (CPU) or a memory and / or a register.

[0109] Figure 7 The following are diagrams showing an embodiment for reference in explaining the operation of the antenna signal quality control device according to one embodiment of the present invention.

[0110] Reference Figure 7 As shown in operation 411 , the first terminal 21 transmits the first data according to the request of the signal quality control device 100 .

[0111] The signal quality control device 100 determines the rotation direction and angle of the antenna 1 according to the signal quality of the first data, and as shown in operation 412 , sends a first adjustment signal including the determined rotation direction and angle to the clamping device 10 .

[0112] Therefore, as shown in operation 413 , the clamping device 10 can adjust the rotation angle of the antenna 1 based on the first adjustment signal.

[0113] If the first angle adjustment of the antenna 1 is completed, as shown in operation 421 , the second terminal 22 transmits the second data according to the request of the signal quality control device 100 .

[0114] The signal quality control device 100 determines the rotation direction and angle of the antenna 1 according to the signal quality of the second data, and as shown in operation 422 , sends a second adjustment signal including the determined rotation direction and angle to the clamping device 10 .

[0115] Therefore, as shown in operation 423 , the clamping device 10 can readjust the rotation angle of the antenna 1 based on the second adjustment signal.

[0116] If the second angle adjustment of the antenna 1 is completed, as shown in operation 431 , the third terminal 23 transmits the third data according to the request of the signal quality control device 100 .

[0117] The signal quality control device 100 determines the rotation direction and angle of the antenna 1 according to the signal quality of the third data, and as shown in operation 432 , sends a third adjustment signal including the determined rotation direction and angle to the clamping device 10 .

[0118] Therefore, as shown in operation 433 , the clamping device 10 can readjust the rotation angle of the antenna 1 based on the third adjustment signal.

[0119] If the third angle adjustment of the antenna 1 is completed, as shown in operation 441 , the fourth terminal 24 transmits fourth data according to the request of the signal quality control device 100 .

[0120] The signal quality control device 100 determines the rotation direction and angle of the antenna 1 according to the signal quality of the fourth data, and as shown in operation 442 , sends a fourth adjustment signal including the determined rotation direction and angle to the clamping device 10 .

[0121] Therefore, as shown in operation 443 , the clamping device 10 can readjust the rotation angle of the antenna 1 based on the fourth adjustment signal.

[0122] As described above, the left and right rotation of the antenna 1 can be preferentially adjusted through work 411 to work 443. If the signal quality of the antenna 1 does not meet the target value, work 411 to work 443 are re-executed to adjust the up and down rotation of the antenna 1.

[0123] The signal quality control device 100 may receive the first data to the fourth data from a plurality of terminal devices 20 , for example, from the first terminal 21 to the fourth terminal 24 in sequence, or may receive the data simultaneously.

[0124] Specifically, Figure 7 In connection with the work 411, work 421, work 431, and work 441 shown, when the first terminal 21 to the fourth terminal 24 are configured at different positions in space, the first data to the fourth data can be sent to the signal quality control device 100 sequentially or simultaneously. When the terminal device 20 is embodied in the form of a drone or is installed in a drone, as the position of the terminal device 20 changes, multiple quality measurement data (such as the first data to the fourth data) can be sent sequentially to the communication unit 120 of the signal quality control device 100.

[0125] The working process of the antenna signal quality control device of the present invention described above is described in more detail as follows.

[0126] Figure 8 and Fig. 9 The figure shows the working process of the signal quality control method of the antenna according to one embodiment of the present invention.

[0127] Reference Figure 8 The signal quality control device 100 requests the first data from the first terminal 21 among the n terminal devices 20 arranged in the network (step S110, step S120).

[0128] When the first data is received from the first terminal 21 (step S130), the signal quality control device 100 checks whether the difference between the signal quality target value QR based on the transmission signal of the antenna 1 and the signal quality measurement value Q1 based on the first data is 0 (or within the error range). If the difference is 0 (or within the error range) (step S140), the signal quality control device 100 requests the second data from the second terminal 22 in the next order (steps S170, S180, and S120).

[0129] On the other hand, in step S140, if the difference is not 0 (or is not within the error range), the signal quality control device 100 preferentially determines the rotation direction as the left-right direction, and determines the rotation angle in the left-right direction (step S150). The signal quality control device 100 may determine the rotation angle according to the difference in step S140 or determine the rotation angle according to a determined value.

[0130] The signal quality control device 100 sends a left-right adjustment signal including the rotation direction and rotation angle determined in step S150 to the clamping device 10 (step S160). Thus, the clamping device 10 can adjust the rotation of the antenna 1 according to the received left-right adjustment signal.

[0131] Afterwards, the signal quality control device 100 repeatedly performs step S120 to step S180 until the nth left-right adjustment signal including the rotation direction and the rotation angle determined based on the nth data received from the nth terminal is transmitted to the clamping device 10 .

[0132] Therefore, the clamping device 10 adjusts the rotation in the left-right direction of the antenna 1 n times. However, the case where the difference value of step S140 is 0 (or within the error range) can be excluded.

[0133] After the signal quality control device 100 sends the nth left and right adjustment signal to the clamping device 10, the signal quality control device 100 performs Fig. 9 The step after "A".

[0134] Reference Fig. 9 The signal quality control device 100 confirms that the signal quality target value QR of the signal transmitted by antenna 1 is consistent with the signal quality target value QR of the signal transmitted by antenna 1. Figure 8The signal quality control device 100 determines whether the difference between the signal quality measurement value QN of the nth data last measured in the step S210 is 0 (or within the error range). If the difference is 0 (or within the error range) (step S210), the signal quality control device 100 determines that the signal quality of the antenna 1 meets the target value, and thus the signal quality control operation can be terminated.

[0135] On the other hand, in step S210, if the difference is not 0 (or is not within the error range), the signal quality control device 100 re-requests the first data from the first terminal 21 among the n terminal devices 20 configured in the network (steps S220 and S230).

[0136] Afterwards, when the first data is received from the first terminal 21 (step S240), the signal quality control device 100 checks whether the difference between the signal quality target value QR of the transmission signal based on the antenna 1 and the signal quality measurement value Q1 based on the first data is 0 (or within the error range). If the difference is 0 (or within the error range) (step S250), the signal quality control device 100 requests the second data from the second terminal 22 in the next order (step S290, step S230).

[0137] On the other hand, in step S250, if the difference is not 0 (or is not within the error range), the signal quality control device 100 determines the rotation direction as the up-down direction, and determines the rotation angle in the up-down direction (step S260). The signal quality control device 100 may determine the rotation angle according to the difference in step S250 or determine the rotation angle according to a determined value.

[0138] The signal quality control device 100 sends an up / down adjustment signal including the rotation direction and rotation angle determined in step S260 to the clamping device 10 (step S270). Thus, the clamping device 10 can adjust the up / down rotation of the antenna 1 according to the received up / down direction adjustment signal.

[0139] Afterwards, the signal quality control device 100 repeatedly performs step S230 to step S290 until the nth up / down adjustment signal including the rotation direction and the rotation angle determined based on the nth data received from the nth terminal is sent to the clamping device 10 .

[0140] Therefore, the clamping device 10 adjusts the rotation in the up-down direction of the antenna 1 n times. However, the case where the difference value in step S250 is 0 (or within the error range) can be excluded.

[0141] If the signal quality of the antenna 1 still does not meet the target value after the nth left and right adjustment signal is sent to the clamping device 10, the signal quality control device 100 may Figure 8As another example, if the signal quality still does not meet the target value after adjusting the left-right rotation and the up-down rotation of the antenna 1, the signal quality control device 100 can guide and end the related work.

[0142] An embodiment of the antenna signal quality control method of the present invention using the antenna signal quality control device as described above is briefly described as follows.

[0143] like Figures 6 to 9 As shown, an embodiment of the signal quality control method of the antenna of the present invention includes the following steps: requesting signal quality measurement data from one of a plurality of terminal devices arranged at a specified position in a network according to a preset order; calculating a signal quality measurement value of the antenna based on the signal quality measurement data received from one of the terminal devices; comparing the signal quality target value of the antenna with the calculated signal quality measurement value, and determining the rotation direction and angle of the antenna according to the difference; and sending an adjustment signal containing the determined rotation direction and angle information of the antenna to a clamping device for adjusting the rotation of the antenna.

[0144] Among them, the step of requesting signal quality measurement data is a step executed by the communication unit 120 that receives signal quality measurement data from multiple terminal devices 20 configured at a specified position in the network. It is a step in which an electronic terminal with communication function requests signal quality measurement data from a terminal device 20 based on a preset order among multiple terminal devices 20.

[0145] Meanwhile, the step of calculating the signal quality measurement value is a step of determining the rotation angle adjustment value related to the left-right direction and / or the up-down direction of the antenna 1 based on the quality measurement data received from the corresponding terminal device 20 requested by the step of requesting the above-mentioned signal quality measurement data. This can be defined as a step performed by the signal quality calculation unit 140 and the rotation determination unit 150.

[0146] Moreover, the step of sending to the clamping device is the following step, that is, if the rotation angle adjustment value of the antenna 1 is determined by the step of determining the rotation direction and angle of the antenna, the control unit 110 is used to send an adjustment signal containing the rotation direction and angle information of the antenna to the clamping device.

[0147] The above description is merely illustrative of the technical concept of the present invention. A person skilled in the art in the technical field to which the present invention belongs may make various modifications and variations without departing from the essential characteristics of the present invention.

[0148] Therefore, the embodiments disclosed in the present invention are used to illustrate the technical ideas of the present invention, but not to limit the scope of the technical ideas of the present invention. The scope of protection of the present invention is explained by the following invention claims, and all technical ideas within the equivalent scope should be interpreted as included in the invention claims of the present invention.
