Therefore, the CPE can be widely applied to occasions without a wired network, such as rural areas, towns, hospitals, factories, cells and the like. The fifth generation mobile communication technology (5G) is favored by users due to its higher communication speed. For example, the transmission rate when data is transmitted by 5G mobile communication is hundreds of times faster than the transmission rate when data is transmitted by 4G mobile communication. Millimeter wave signals are the main means for implementing 5G mobile communications. However, when the millimeter wave antenna is applied to a network device, it is easily blocked by an object, so that the received signal is weak, and the communication effect of the network device is poor. In order to avoid the millimeter wave antenna from being blocked, a manner of rotating the millimeter wave antenna is generally used, however, when the millimeter wave antenna rotates, abnormality is likely to occur, which may cause damage to a device driving the millimeter wave antenna.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

Referring to fig. 1, fig. 1 is a schematic view of an application environment of a network device according to an embodiment of the present disclosure. The network device 1 is a Customer Premises Equipment (CPE). The network device 1 communicates with the base station 3, receives a first network signal sent by the base station 3, and converts the first network signal into a second network signal. The second network signal can be used by terminal equipment 5 such as a tablet computer, a smart phone, a notebook computer and the like. The first network signal may be, but is not limited to, a fifth generation mobile communication technology (5G) signal, and the second network signal may be, but is not limited to, a Wireless Fidelity (WiFi) signal. The CPE can be widely applied to rural areas, towns, hospitals, factories, cells and the like, and the first network signals which can be accessed by the CPE can be wireless network signals, so that the cost of laying a line network can be saved.

Referring to fig. 2, fig. 3 and fig. 4 together, fig. 2 is a schematic structural diagram of a network device according to an embodiment of the present application; FIG. 3 is a schematic diagram of the network device of FIG. 2 with the housing removed; fig. 4 is a circuit block diagram of a network device according to another embodiment of the present application. The network device 1 comprises a housing 220. The housing 220 may be in the shape of a multi-sided cylindrical barrel, or a cylindrical barrel. The material of the housing 220 may be, but is not limited to, an insulating material such as plastic. It is understood that in other embodiments, the network device 1 may not include the housing 220.

The network device 1 further comprises a first signal receiving antenna 110 and a signal converter 120. The first signal receiving antenna 110 is rotatable to receive first network signals from different directions, and the signal converter 120 converts the first network signal with the strongest signal among the first network signals received by the first signal receiving antenna 110 from different directions into a second network signal.

When the network device 1 includes a housing 220, the first signal receiving antenna 110 and the signal converter 120 may be disposed in the housing 110.

The first signal receiving antenna 110 may be, but is not limited to, a millimeter wave signal receiving antenna or a terahertz signal receiving antenna. Accordingly, the first network signal may be, but is not limited to, a millimeter wave signal or a terahertz signal. Currently, in the fifth generation mobile communication technology (5th generation wireless systems, 5G), according to the specification of the 3GPP TS 38.101 protocol, a New Radio (NR) of 5G mainly uses two sections of frequencies: FR1 frequency band and FR2 frequency band. Wherein, the frequency range of the FR1 frequency band is 450 MHz-6 GHz, also called sub-6GHz frequency band; the frequency range of the FR2 frequency band is 24.25 GHz-52.6 GHz, and belongs to the millimeter Wave (mm Wave) frequency band. The 3GPP Release 15 specification specifies that the current 5G millimeter wave frequency band includes: n257(26.5 to 29.5GHz), n258(24.25 to 27.5GHz), n261(27.5 to 28.35GHz) and n260(37 to 40 GHz). Millimeter wave or terahertz signal have transmission speed advantage such as fast, however, millimeter wave or terahertz signal are sheltered from by external object easily. When there is an object block between the first signal receiving antenna 110 and the base station 3, the signal strength of the first network signal received by the first signal receiving antenna 110 is weak, and at this time, if the first network signal with weak signal strength is converted into the second network signal, the signal strength of the obtained second network signal may also be weak.

For the network device 1 placed at a certain position, the signal strength of the first network signal in each direction of the first signal receiving antenna 110 is different. In the network device 1 provided in this embodiment, the first signal receiving antenna 110 is rotatable, and when the first signal receiving antenna 110 is located in the direction in which the signal strength of the first network signal is strongest, the first signal receiving antenna 110 stays in the direction in which the signal strength of the first network signal is strongest. The signal converter 120 converts the first network signal with the strongest signal received by the first signal receiving antenna 110 into the second network signal. The signal converter 120 in the network device 1 in this embodiment converts the first network signal with the strongest signal into the second network signal, so as to ensure the signal strength of the second network signal, and further ensure the communication quality when communicating by using the second network signal.

In one embodiment, the first signal receiving antenna 110 can be rotated manually or automatically, as long as the first signal receiving antenna 110 can be rotated. In this application, a device for driving the first signal receiving antenna 110 to rotate automatically will be described later, taking as an example that the first signal receiving antenna 110 can be rotated automatically.

Optionally, in an embodiment, the network device 1 further includes a controller 130. The controller 130 is configured to determine a direction of the strongest signal strength according to the signal strength of the first network signal, and control the first signal receiving antenna 110 to rotate to the direction of the strongest first network signal.

Specifically, the controller 130 is electrically connected to the first signal receiving antenna 110, when the first signal receiving antenna 110 rotates, the first signal receiving antenna 110 can receive the first network signals in each direction, and the controller 130 compares the strength of the first network signals in each direction and determines the direction with the strongest signal strength. In this embodiment, the controller 130 controls the first signal receiving antenna 110 to rotate to the direction in which the first network signal is the strongest, so as to realize the automatic control of the rotation of the first signal receiving antenna 110.

Referring to fig. 5 and fig. 6 together, fig. 5 is a schematic structural diagram of a network device according to another embodiment of the present application; FIG. 6 is a schematic diagram of a driver according to an embodiment. Only the components of the network device 1 related to the first signal receiving antenna 110 and driving said first signal receiving antenna 110 are illustrated in fig. 5, while other components of said network device 1 are omitted. The network device 1 further comprises a base 140, a bracket 150, and a driver 160. The base 140 is rotatably connected to the bracket 150, the first signal receiving antenna 110 is disposed on the bracket 150, and the driver 160 is configured to receive a control signal from the controller 130 and drive the bracket 150 to rotate to a direction in which the first network signal is strongest relative to the base 140 under the control of the control signal.

The base 140 is stationary, for example, the base 140 may be directly or indirectly fixed to a housing 220 (see fig. 2) of the network device 1. The bracket 150 is rotatably connected to the base 140, and when the first signal receiving antenna 110 is disposed on the bracket 150, and the driver 160 drives the bracket 150 to rotate, the bracket 150 drives the first signal receiving antenna 110 to rotate. The driver 160 may include, but is not limited to including, a motor, etc. The base 140 forms an enclosure and the driver 160 is disposed within the enclosure formed by the base 140.

The first signal receiving antenna 110 includes a plurality of receiving units 112 to form an antenna array. In the present embodiment, the number of the receiving units 112 is 2 as an example. The receiving unit 112 is disposed on a substrate 113. The substrate 113 may be, but not limited to, a circuit board or the like.

In one embodiment, referring to fig. 6, the driver 160 includes a motor 161 and a reducer 162. The motor 161 is fixed to the base 140, the motor 161 is controlled by the control signal to rotate, a step angle of the motor 161 is a first angle, the speed reducer 162 is engaged with an output shaft of the motor 161, the speed reducer 162 is rotationally connected to the bracket 150, and the speed reducer 162 is used for converting the first angle into a second angle, wherein the second angle is smaller than the first angle.

The driver 160 further includes a driving shaft 165, the driving shaft 165 is fixedly connected to the driving gear 164, and the driving shaft 165 is further fixedly connected to the bracket 150. When the driving gear 164 rotates, the driving shaft 165 rotates to drive the bracket 150 to rotate, and when the bracket 150 rotates, the first signal receiving antenna 110 disposed on the bracket 150 is driven to rotate.

Further, the driver 160 further includes a bearing 166, the bearing 166 is sleeved on the driving shaft 165, and the driving gear 164 is connected to the driving shaft 165 through the bearing 166.

The network device 1 further comprises a circuit board 180. The signal converter 120 and the controller 130 in the network device 1 are both disposed on the circuit board 180. The circuit board 180 is also referred to as a platelet. The components for driving the first signal receiving antenna 110 to operate are mainly disposed on the circuit board 180. For example, the circuit board 180 may further include a power supply circuit, a protection circuit, and the like, so as to assist the signal converter 120 to convert the first network signal into the WiFi signal.

The step angle is a mechanical angle that the output shaft of the motor 161 rotates for one pulse of the control signal. The pitch angle of the motor 161 may be, but is not limited to, 3 °, 1.5 °, 0.75 °, 3.6 °, or 1.8 °. The larger the step angle, the larger the angle by which an output shaft of the motor 161 is rotated by one pulse of the control signal, the larger the angle by which the first signal receiving antenna 110 is driven to rotate; conversely, the smaller the step angle, the smaller the angle through which the output shaft of the motor 161 is rotated by one pulse of the control signal, and the smaller the angle through which the first signal receiving antenna 110 is rotated. When the step angle is larger, one pulse of the control signal causes the output shaft of the motor 161 to rotate by a larger angle, and the output shaft of the motor 161 needs to rotate by one turn with fewer pulses; conversely, when the step angle is smaller, one pulse of the control signal causes the output shaft of the motor 161 to rotate by a smaller angle, and the output shaft of the motor 161 needs to rotate by one turn more pulses. For example, for a motor 161 with a step angle of 1.8 °, the number of pulses required for one revolution is 360/1.8 — 200. Generally speaking, the stepping angle of the motor 161 is larger, if the reducer 162 is not used, and if the motor 161 is directly used to drive the support 150, the angle of each rotation of the support 150 is larger, and the angle of each rotation of the first signal receiving antenna 110 disposed on the support 150 is larger, which further results in that the number of the first network signals received by the first signal receiving antenna 110 during one rotation cycle is smaller, and further may cause inaccurate subsequent determination of the first network signal with the strongest signal according to the signal strength of each acquired first network signal. For example, when the step angle of the rotation of the motor 161 is a first angle and the reducer 162 is not used, one pulse of the control signal causes the bracket 150 to rotate from the position a to the position B, and the direction of the first network signal with the strongest signal is located at the position C between the position a and the position B, then, because the step angle is too large, the motor 161 cannot drive the first signal receiving antenna 110 to rotate to the point C, and the determination of the first network signal with the strongest signal according to the signal strength of each acquired first network signal is inaccurate.

The speed reducer 162 is arranged in the network device 1, the first angle is converted into a smaller second angle, and when the motor 161 drives the bracket 150 through the speed reducer 162, the bracket 150 can rotate for a circle for a plurality of times. In other words, compared to the network device 1 without using the reducer 162, the reducer 162 in this embodiment may enable the first signal receiving antenna 110 to receive the first network signals in more directions, so as to improve the accuracy of determining the first network signal with the strongest signal according to the signal strength of each acquired first network signal.

In one embodiment, the reducer 162 includes a P-speed gear set 163 and a drive gear 164. Each stage of gear set 163 includes a first gear 1631 and a second gear 1632 that are coaxially and fixedly connected. The radius of the first gear 1631 in each stage of gear set 163 is greater than the radius of the second gear 1632 in the same stage of gear set 163. A first gear 1631 of the first gear set 163 of the P-gear set 163 engages the output shaft of the motor, and a second gear 1632 of the first gear set 163 engages the first gear 1631 of the second gear set 163. A first gear 1631 of the Q-th stage gear set 163 engages a second gear 1632 of the Q-1 th stage gear set 163, and a second gear 1632 of the Q-th stage gear set 163 engages a first gear 1631 of the Q +1 th stage gear set 163. The second gear 1632 of the P-th gear set 163 engages the driving gear 164, and the driving gear 164 is fixedly connected to the bracket 150. Q and P are positive integers, Q is greater than 1 and Q is less than P, the radius of the first gear 1631 in the Q-th gear set 163 is less than the radius of the first gear 1631 in the Q + 1-th gear set 163, and the radius of the first gear 1631 in the P-th gear set 163 is less than the radius of the driving gear 164.

In the present embodiment, the reduction gear 162 is illustrated as including a 2-stage gear set 163. It will be appreciated that reducer 162 may also include a stage 1 gear set 163, a stage 2 gear set 163, a stage 3 gear set 163, or even more stage gear sets 163.

In the present embodiment, the decelerator 162 includes a 2-stage gear set 163. Each stage of gear set 163 includes a first gear 1631 and a second gear 1632 that are coaxially and fixedly connected. The radius of the first gear 1631 in each stage of gear set 163 is greater than the radius of the second gear 1632 in the same stage of gear set 163. For purposes of this description, the 2-stage gear sets are designated as first stage gear set 163a and second stage gear set 163b, respectively. A first gear 1631 of the first stage gear set 163a engages the output shaft of the motor 161 and a second gear 1632 of the first stage gear set 163a engages the first gear 1631 of the second stage gear set 163 b. The second gear 1632 of the second stage gear set 163b engages the drive gear 164. The radius of the first gear 1631 in the first stage gear set 163a is smaller than the radius of the first gear 1631 in the second stage gear set 163, and the radius of the first gear 1631 in the second stage gear set 163b is smaller than the radius of the driving gear 164.

Referring to fig. 9, fig. 9 is a schematic structural diagram of a speed reducer according to another embodiment of the present application. In this embodiment, when the speed reducer 162 includes the 1-stage gear set 163, the gear set 163 includes a first gear 1631 and a second gear 1632 which are coaxially and fixedly connected, and the radius of the first gear 1631 is larger than that of the second gear 1632; the first gear 1631 and an output shaft of the motor 161, and the second gear 1632 engages the drive gear 164.

Referring to fig. 10, fig. 10 is a schematic structural diagram of a speed reducer according to another embodiment of the present application. In the present embodiment, when the speed reducer 162 includes the 3-stage gear set 163, each stage of the gear set 163 includes a first gear 1631 and a second gear 1632 which are coaxially and fixedly connected. The radius of the first gear 1631 in each stage of gear set 163 is greater than the radius of the second gear 1632 in the same stage of gear set 163. For purposes of the description, 3-stage gear set 163 is named first stage gear set 163a, second stage gear set 163b, and third stage gear set 163c, respectively. A first gear 1631 of the first stage gear set 163a engages the output shaft of the motor, and a second gear 1632 of the first stage gear set 163a engages the first gear 1631 of the second stage gear set 163 b. The second gear 1632 of the second stage gear set 163b engages the first gear 1631 of the third gear set 163, and the second gear 1632 of the third gear set 163 engages the drive gear 164. The driving gear 164 is fixedly connected to the bracket 150. The radius of first gear 1631 in first stage gear set 163a is smaller than the radius of first gear 1631 in second stage gear set 163b, the radius of first gear 1631 in second stage gear set 163b is smaller than the radius of first gear 1631 in third stage gear set 163c, and the radius of first gear 1631 in third stage gear set 163c is smaller than the radius of drive gear 164.

When the number of the gear sets 163 is larger, the smaller the second angle is, the more the accurate control of the rotation angle of the bracket 150 is facilitated, the more the first network signals in more directions are received, and the accuracy of judging the first network signal with the strongest signal according to the signal strength of each acquired first network signal is further facilitated. However, the more gear sets 163, the more time is required for installation of the gear sets 163, and the more space is occupied by the gear sets 163. Therefore, the number of the rotating gear sets 163 can be comprehensively considered in consideration of the accuracy of the rotational angle control of the carrier 150, the time taken to install the gear sets 163, and the space occupied by the gear sets 163.

In the present embodiment, the decelerator 162 includes 3 sets of gear sets 163. The motor 161 is fixed to the base 140, P is 3, and the first gear 1631 of the first-stage gear set 163 is disposed away from the base 140 compared with the second gear 1632 of the first-stage gear set 1631 and the gear set 163; a first gear 1631 of the second gear 1632 gear set 163 is disposed away from the base 140 as compared to a second gear 1632 of the second gear 1632 gear set 163; the first gear 1631 of the third gear set 163 is disposed adjacent to the base 140 compared to the second gear 1632 of the third gear set 163. In this embodiment, the gear set 163 is disposed in a manner such that the gear set 163 occupies a small volume, which is beneficial to improving the integration level of the speed reducer 162.

In this embodiment, the driver 160 drives the bracket 150 to rotate, so as to drive the first signal receiving antenna 110 to rotate in the first plane. In other embodiments, the driver 160 can further drive the bracket 150 to rotate to drive the first signal receiving antenna 110 to rotate in a first plane, and can further drive the bracket 150 to drive the first signal receiving antenna 110 to rotate in a second plane, where the first plane is different from the second plane. For example, the first plane may be an XY plane and the second plane may be a YZ plane.

When the driver 160 drives the bracket 150 to rotate to drive the first signal receiving antenna 110 to rotate in the first plane and the second plane, the first signal receiving antenna 110 can receive the first network signals in more directions. And the accuracy of judging the first network signal with the strongest signal according to the signal strength of the acquired first network signals is improved.

Referring to fig. 15 and 16 together, fig. 15 is a schematic structural diagram of a network device according to another embodiment of the present application; fig. 16 is a top view of fig. 15. The network device 1 of the present embodiment further includes a heat sink 190. The network device 1 comprising the heat sink 190 may be incorporated into the network device 1 provided in any of the previous embodiments. The first signal receiving antenna 110 comprises a receiving face 111 for receiving the first network signal. The network device 1 further comprises a heat dissipation element 190, wherein the heat dissipation element 190 is directly or indirectly disposed on a surface of the first signal receiving antenna 110 facing away from the receiving surface 111.

The heat sink 190 may be made of, but not limited to, metal with good thermal conductivity. The heat dissipation member 190 is used for dissipating heat when the first signal receiving antenna 110 operates, so as to prevent the first signal receiving antenna 110 from being unstable in performance due to overheating when the first signal receiving antenna 110 operates. In the present embodiment, the heat sink 190 further includes a plurality of heat dissipation fins 191, and the plurality of heat dissipation fins 191 are spaced apart from each other to improve a heat dissipation effect. Further, the size of the heat radiating fins 191 adjacent to the rotational axis of the first signal receiving antenna 110 is larger than the size of the heat radiating fins 191 away from the rotational axis.

Since there is a gap between the two ends of the first signal receiving antenna 110 and the housing 220 of the network device 1, the two ends of the first signal receiving antenna 110 are more easily heat-dissipated than the portion of the first signal receiving antenna 110 close to the rotation axis. In the network device 1 of the present application, the size of the heat radiation fins 191 adjacent to the rotation axis of the first signal receiving antenna 110 is set larger than the size of the heat radiation fins 191 distant from the rotation axis, and therefore, the uniformity of the heat radiation effect at each portion of the first signal receiving antenna 110 can be improved.

Further, in one embodiment, the length of the heat sink 191 is increased in the direction of the rotation axis from the end of the first signal receiving antenna 110. Such arrangement of the heat sink 191 can improve uniformity of heat dissipation effect at each portion of the first signal receiving antenna 110, and on the other hand, the heat sink does not easily touch other components in the network device 1 when the first signal receiving antenna 110 rotates.

Further, the heat sink 190 further includes a heat sink body 192, and the heat sink body 192 is attached to a surface of the first signal receiving antenna 110 away from the receiving surface 111.

The heat dissipating body 192 may be, but is not limited to, rectangular in shape.

When the heat sink 190 further includes a heat sink body 192, the contact area between the heat sink body 192 and the first signal receiving antenna 110 is large, so that the heat of the first signal receiving antenna 110 can be rapidly dissipated.

In the present embodiment, the network device 1 including the fan 240 is shown in the diagram of fig. 2. The fan 240 is disposed corresponding to the first signal receiving antenna 110 for dissipating heat. The fan 240 is used to accelerate the air circulation near the first signal receiving antenna 110, so as to further improve the heat dissipation effect.

Further, a heat dissipation hole 221 is disposed on the housing 220 of the network device 1. The heat dissipation hole 221 communicates with a receiving space formed by the housing 220.

The network device 1 may include, but is not limited to, 8 second signal receiving antennas 210. Alternatively, two second signal receiving antennas 210 may constitute an antenna group 210a, which is disposed on the same substrate.

Due to the uncertainty of the position of the base station 3 transmitting the third network signal, there is also an uncertainty of the direction of transmission of the third network signal. The plurality of second signal receiving antennas 210 are fixed in position and are not rotatable. By distributing the second signal receiving antennas 210 along the circumference of the network device 1, a third network signal in multiple directions can be detected. And further, the accuracy of judging the third network signal with the strongest signal according to the signal strength of each acquired third network signal can be improved.

In one embodiment, the signal converter 120 converts at least one or more third network signals with the strongest signal strength from the plurality of second signal receiving antennas 210 into a fourth network signal.

For example, the number of the second signal receiving antennas 210 is M, and the signal converter 120 is configured to select one or N second signal receiving antennas 210 from the M second signal receiving antennas 210 according to the strength of the third network signal received by the second signal receiving antennas 210. When the number of the selected second signal receiving antennas 210 is one, the strength of the third network signal received by the selected second signal receiving antennas 210 is greater than the strength of the third network signal received by each of the remaining second signal receiving antennas 210 alone. When the number of the selected second signal receiving antennas 210 is N, the sum of the signal strengths of the selected N second signal receiving antennas 210 is greater than the sum of the strengths of the third network signals received by any remaining N second signal receiving antennas 210 of the M second signal receiving antennas 210. Wherein M and N are both positive integers, for example, M is equal to but not limited to 8, and N is equal to but not limited to 4.

Please refer to the foregoing description for the first signal receiving antenna 110, the second signal receiving antenna 210, the first network signal, the second network signal, the third network signal, and the fourth network signal, which is not repeated herein.

In one embodiment, referring to fig. 4 and 13, the network device 1 further includes a base 140, a support 150, a driver 160, and a controller 130. The base 140 is fixed to the housing 220, the bracket 150 is rotatably connected to the base 140, the bracket 150 is used for carrying the first signal receiving antenna 110, and the driver 160 is used for driving the bracket 150 to move under the control of the controller 130. The structure of the driver 160 is described in the foregoing, and is not described herein again.

The network device 1 includes a first signal receiving antenna 110, a bracket 150, a base 140, and a signal converter 120, where the first signal receiving antenna 110 is supported on the bracket 150, the bracket 150 is rotatably connected to the base 140, when the network device 1 is in a working state, the first signal receiving antenna 110 is at a preset position compared with the base 140, when the first signal receiving antenna 110 is at the preset position compared with the base 140, the signal strength of the first signal receiving antenna 110 receiving a first network signal is greater than the signal strength of the first network signal received by the first signal receiving antenna 110 at other positions, and the signal converter 120 is configured to convert the first network signal with the strongest signal received by the first signal receiving antenna 110 into a second network signal.

Please refer to the foregoing description for the first signal receiving antenna 110, the bracket 150, the base 140, the signal converter 120, the first network signal, and the second network signal, which is not described herein again. In an embodiment, the network device 1 further includes a driver 160 and a controller 130, when the first signal receiving antenna 110 receives a test command, the controller 130 controls the driver 160 to drive the bracket 150 to rotate at least one circle compared to the base 140 to obtain signal strengths of the first network signals in various directions, the controller 130 determines a direction with the strongest signal strength according to the signal strengths of the first network signals in various directions, and the controller 130 controls the driver 160 to drive the bracket 150 to rotate to a direction with the strongest signal strength.

The network device 1 has a test state and an operating state, the test state being located before the operating state. When the network device 1 is in the test state, the first signal receiving antenna 110 in the network device 1 receives the test signal and determines the direction in which the strength of the first network signal is strongest. And when the network device 1 determines the direction of the strongest first network signal in the test state, entering the working state. In other words, when the network device 1 is in an operating state, the first signal receiving antenna 110 is located at a predetermined position compared to the base 140, and at this time, the strength of the first network signal received by the first signal receiving antenna 110 is greater than the strength of the first network signal when the first signal receiving antenna 110 is located at other positions compared to the base 140.

Specifically, the network device 1 further includes a driver 160 and a controller 130. When the network device 1 is in a test state, the first signal receiving antenna 110 receives a test instruction, the controller 130 controls the driver 160 to drive the bracket 150 to rotate at least one circle compared with the base 140 to obtain the signal strength of the first network signal in each direction, the controller 130 determines the direction with the strongest signal strength according to the signal strength of the first network signal in each direction, and the controller 130 controls the driver 160 to drive the bracket 150 to rotate to the direction with the strongest signal strength.

In one embodiment, the network device 1 has a test state and an operating state, the test state preceding the operating state. The network device 1 further includes a memory 230, where the memory 230 stores a comparison table, where the comparison table includes a correspondence between the location of the network device 1 and a direction in which a first network signal strength corresponding to the location of the network device 1 is strongest, when the network device 1 is in a test state, the first signal receiving antenna 110 receives a test instruction, the controller 130 compares the current location of the network device 1 with the comparison table, and when the current location of the network device 1 matches the location of the network device 1 in the comparison table, the controller 130 controls the driver 160 to operate according to the comparison table, so that the first signal receiving antenna 110 is located in the direction in which the first network signal strength corresponding to the matched location is strongest.

For example, referring to fig. 25, fig. 25 is a comparison table of the location of the network device and the direction of the strongest first network signal. The locations of the network device 1 in the lookup table are L1, L2, L3, …, Ln.

When the network device 1 is in a test state, the current position of the network device 1 is Lx, and when the current position Lx of the network device 1 matches L3 in the lookup table, if the first signal receiving antenna 110 is not in the direction P3 corresponding to L3, the controller 130 directly controls the driver 160 to drive the bracket 150 to move so as to drive the first signal receiving antenna 110 to move to the direction P3; if the first signal receiving antenna 110 is in the direction P3 corresponding to L3, the controller 130 does not need to drive the driver 160 to rotate any more.

The network device 1 according to this embodiment can control the driver 160 to operate according to the current location of the network device 1 and the comparison table, so as to quickly drive the first signal receiving antenna 110 to the direction in which the signal strength of the first network signal is strongest.

With reference to the structure of the network device 1 provided in each of the above embodiments, a processing strategy when an abnormality occurs in the motor 161 in the driver 160 in the network device 1 will be described below. The driver 160 includes a driving chip 169 in addition to the motor 161. Referring to fig. 26, fig. 26 is a circuit block diagram of a network device according to an embodiment of the present application. The network device 1 includes a base 140, a support 150, a driving chip 169, a motor 161, a signal receiving antenna (here, the first signal receiving antenna 110 described above), a signal converter 120, a detection circuit 290, and a controller 130. The base 140 is rotatably connected to the bracket 150, the driving chip 169 is electrically connected to the motor 161, the driving chip 169 is used for driving the motor 161 to rotate, when the motor 161 rotates, the bracket 150 is driven to rotate compared to the base 140, and the first signal receiving antenna 110 is disposed on the bracket 150 and rotates along with the rotation of the bracket 150 to receive first network signals from different directions. The signal converter 120 converts the first network signal with the strongest signal from the first network signals received by the first signal receiving antenna 110 from different directions into the second network signal. The detection circuit 290 is configured to detect a driving current when the driving chip 169 drives the motor 161 to rotate, and the controller 130 is configured to compare the driving current with a preset current to determine whether the motor 161 is abnormal during rotation, and control the driving chip 169 to adjust a driving signal when it is determined that the motor 161 is abnormal during rotation.

The abnormality includes, but is not limited to, a stalling or seizure of the motor 161. The details of stall and stuck are as follows.

The seizure is a common abnormality occurring in the motor 161, and if the motor 161 is not abnormal, the motor 161 is normally rotated by the driving signal generated by the driving chip 169, but due to various abnormalities, the motor 161 cannot be normally rotated upon receiving the driving signal generated by the driving chip 169, and thus, the motor 161 is intermittently rotated and stopped.

The rotation lock is also a common abnormality occurring in the motor 161, and if the motor 161 is not abnormal, the motor 161 is normally rotated by the driving signal generated from the driving chip 169, but due to various abnormalities, the motor 161 is not normally rotated but is blocked and cannot rotate upon receiving the driving signal generated from the driving chip 169.

In this embodiment, the detection circuit 290 is added in the network device 1, the detection circuit 290 detects the driving current when the driving chip 169 drives the motor 161, the controller 130 determines whether an abnormality occurs in the rotation process of the motor 161 according to the driving current, and when an abnormality occurs, the current rotation state of the motor 161 is changed to eliminate the abnormality, so that the motor 161 is prevented from being damaged, and the normal operation of the network device 1 is ensured.

In one embodiment, the detection circuit 290 compares the driving current detected within a first preset time with a preset current, and when the driving current detected within the first preset time is greater than the preset current, the controller 130 determines that the stalling of the motor 161 occurs during the rotation process.

For example, the first predetermined time may be, but not limited to, 10mS, and when the motor 161 is blocked during the rotation process and the motor 161 is blocked and cannot rotate, the energy output from the driving chip 169 to the motor 161 cannot be converted into the kinetic energy for driving the bracket 150 by the motor 161, but is reflected in that the driving current on the path between the driving chip 169 and the motor 161 is increased and converted into the heat energy. Therefore, in the present embodiment, the detection circuit 290 detects the change in the driving current to determine whether the motor 161 is locked.

In one embodiment, when the motor 161 is locked during rotation, the controller 130 controls the driving chip 169 to send a driving signal to drive the motor 161 to change the rotation direction.

For example, when the output shaft of the motor 161 rotates clockwise in the driving signal generated by the driving chip 169, and the controller 130 determines that the motor 161 is locked in rotation, the controller 130 drives the output shaft of the motor 161 to rotate counterclockwise. When the output shaft of the motor 161 rotates counterclockwise in response to the driving signal generated by the driving chip 169, the controller 130 drives the output shaft of the motor 161 to rotate clockwise when the controller 130 determines that the motor 161 is locked during rotation. For example, when the output shaft of the motor 161 rotates clockwise to drive the bracket 150 to rotate in a predetermined direction, the bracket 150 may block a signal transmission line and the like in the network device 1, so that the bracket 150 cannot rotate in the predetermined direction, and when the rotation direction of the motor 161 is changed, the signal transmission line may be separated from the blocked state, so that the motor 161 can rotate normally.

Further, when the motor 161 is still abnormal during rotation after the motor 161 changes the direction of rotation for a first threshold time, the controller 130 controls the motor 161 to stop rotating. The first threshold time may be, but is not limited to, 5S, and when the motor 161 is still abnormal during the rotation process after the motor 161 changes the rotation direction for the first threshold time, it indicates that the change of the rotation direction of the motor 161 cannot eliminate the abnormality of the motor 161, and the controller 130 controls the motor 161 to stop rotating, so as to prevent the motor 161 from being burnt. In one embodiment, when the controller 130 determines that an abnormality occurs in the motor 161 during rotation, the controller 130 controls the motor 161 to increase the rotational torque during rotation. Increasing the rotational torque while the motor 161 is rotating can also eliminate some of the anomalies.

Further, when the motor 161 is abnormal during the rotation process after the motor 161 increases the rotation torque for a second threshold time, the controller 130 controls the motor 161 to stop the rotation, so as to prevent the motor 161 from being burnt. The second threshold time may be, but is not limited to, 5S, and the second threshold time may be the same as the first threshold time or different from the second threshold time.

In one embodiment, the detection circuit 290 compares the driving current detected in the first preset time with a preset current, and when the driving current detected in the first preset time is greater than the preset current in a part of the time period and the driving current is less than the preset current in another part of the time period, the controller 130 determines that the motor 161 is stuck during the rotation.

Since intermittent rotation and stop are exhibited when the motor 161 is jammed. When the motor 161 is stopped, the energy output from the driving chip 169 to the motor 161 cannot be converted into kinetic energy by the motor 161 to drive the support 150 to rotate, but appears as an increase in driving current on the path between the driving chip 169 and the motor 161. When the motor 161 rotates, the current on the path between the driving chip 169 and the motor 161 is normal, which represents the stability of the driving current. Therefore, in the present embodiment, the detection circuit 290 detects the driving current to determine whether the motor 161 is stuck during the rotation, so that the accuracy of determining the stuck time of the motor 161 can be achieved.

When the motor 161 is jammed during rotation, the controller 130 controls the driving signal from the driving chip 169 to drive the motor 161 to change the direction of rotation. For a specific way that the controller 130 controls the driving chip 169 to send out the driving signal to drive the motor 161 to change the rotating direction, please refer to the foregoing description, which is not repeated herein.

Further, when the motor 161 is still abnormal during rotation after the motor 161 changes the direction of rotation for a first threshold time, the controller 130 controls the motor 161 to stop rotating. The threshold time may be, but is not limited to, 5S, and when the motor 161 is still abnormal during the rotation process after the motor 161 changes the rotation direction for the first threshold time, it means that the change of the rotation direction of the motor 161 cannot eliminate the abnormality of the motor 161, and the controller 130 controls the motor 161 to stop rotating, so as to prevent the motor 161 from being burnt.

In one embodiment, when the controller 130 determines that an abnormality occurs in the motor 161 during rotation, the controller 130 controls the motor 161 to increase the rotational torque during rotation. Increasing the rotational torque while the motor 161 is rotating can also eliminate some of the anomalies.

In one embodiment, the controller 130 is further configured to compare the signal strength of the second network signal with a preset signal strength to assist in determining whether the motor 161 is abnormal during the rotation process, wherein the preset signal strength is equal to the strength of the second network signal corresponding to the strongest signal strength of the first network signal.

Specifically, when the strength of the second network signal is less than a preset signal strength and does not reach the preset signal strength within a second preset time, the controller 130 determines that the motor 161 is abnormal during the rotation process, wherein the second preset time is greater than or equal to a time taken by the bracket 150 to rotate one turn compared to the base 140 when the motor 161 normally rotates.

Further, the network device 1 includes a power interface 310 and a switch 320 (see fig. 2). When the power interface 310 is connected to an operating voltage and the switch 320 is turned on, the controller 130 controls the detection circuit 290 to start detecting the driving current when the driving chip 169 drives the motor 161.

When the network device 1 is switched on and the switch 320 is turned on, the motor 161 usually drives the bracket 150 to rotate relative to the base 140, and at this time, the controller 130 controls the detection circuit 290 to start detecting, so as to improve the probability of detecting whether the motor 161 is abnormal.

In one embodiment, the controller 130 controls the detection circuit 290 to periodically detect the driving current when the driving chip 169 drives the motor 161 at a first detection frequency when the strength of the first network signal is less than a preset signal strength, wherein the preset signal strength is equal to the maximum signal strength of the first network signal.

Further, when the strength of the first network signal is equal to a preset signal strength, the controller 130 controls the detection circuit 290 to periodically detect the driving current when the driving chip 169 drives the motor 161 at a second detection frequency, wherein the second detection frequency is smaller than the first detection frequency.

With reference to the above embodiments, when the motor 161 is abnormal during rotation, the controller 130 is further configured to turn on the fan 240 in the network device 1 to dissipate heat of the network device 1, so as to prevent the motor 161 and other related devices from being damaged. In one embodiment, the controller 130 is configured to control the rotation speed of the fan 240 to increase as the time during which the abnormality is detected increases when the abnormality is not eliminated. When the abnormality is not eliminated, the motor 161 generates more and more heat with the passage of time, and therefore, the control unit 130 controls the rotation speed of the fan 240 to increase, so that heat can be rapidly dissipated to prevent damage to the motor 161 and other related devices.

With reference to the above embodiments, when the motor 161 is abnormal during rotation, the controller 130 is further configured to control the second signal receiving antenna 210 to be turned on. The signal converter 120 converts the third network signal received by the second signal receiving antenna 210 into a fourth network signal. The fourth network signal is available for communication by the terminal device 5. In order to avoid that the communication effect is not good due to the fact that the second network signal is weak as the signal strength of the first network signal received by the first signal receiving antenna 110 is weak when the anomaly is not eliminated subsequently. Further, in the present embodiment, the second signal receiving antenna 210 is turned on immediately when the abnormality is detected, instead of turning on the second signal receiving antenna 210 when the abnormality is not eliminated, and the present embodiment can improve the communication effect of the terminal device 5 performing communication through the network device 1.

In an embodiment, after the controller 130 controls the second signal receiving antenna 210 to be turned on, the second signal receiving antenna 210 is continuously turned on, so as to improve the communication effect of the network device 5 in communicating.

In an embodiment, when the network device 1 is turned on next time, the controller 130 is further configured to control the second signal receiving antenna 210 to operate, and control the first signal receiving antenna 110 to turn off and control the motor 161 to turn off. Because the motor 161 is abnormal, when the network device 1 is turned on next time, the second signal receiving antenna 210 is selected to operate to control the first signal receiving antenna 110 and the motor 161 to be turned off, so that the poor communication effect of the network device 1 caused by the motor 161 being abnormal again is avoided.

In this embodiment, when the strength of the first network signal is smaller than the maximum signal strength of the first network signal, the motor 161 drives the bracket 150 to rotate compared with the base 140, and at this time, the detection is performed at a more frequent detection frequency, which is beneficial to timely finding whether the motor 161 is abnormal or not. When the intensity of the first network signal is equal to the maximum intensity of the first network signal, generally speaking, the probability that the motor 161 continues to rotate is not high, and at this time, the detection is performed at a detection frequency with a lower frequency, which is beneficial to saving the electric energy consumed by the detection circuit 290.

Referring to fig. 27, fig. 27 is a circuit diagram of a network device according to an embodiment of the present application. The detection circuit 290 includes a first resistor R1, a second resistor R2, and a detector 291, and the driving chip 169 includes a first output terminal P1 and a second output terminal P2. The first output terminal P1 is electrically connected to the first resistor R1 and the motor 161, the second output terminal P2 is electrically connected to the second resistor R2 and the motor 161, and the detector 291 is electrically connected to two terminals of the first resistor R1 and two terminals of the second resistor R2 for collecting the driving current. An output terminal of the detector 291 is electrically connected to the controller 130 to output the driving current to the controller 130.

The first output terminal P1 is used for outputting a first ac signal, the second output terminal P2 is used for outputting a second ac signal, and the driving motor 161 is driven by the first ac signal and the second ac signal. Typically, the first ac signal and the second ac signal have the same amplitude and are 90 ° out of phase with each other.
