It should be noted that when a component is referred to as being "electrically connected" to another component, it may include the connection between different components of the circuit configuration via physical traces, such as copper foils or wires of a PCB, that may transmit electrical signals.
The embodiment of the present application provides a signal transmission apparatus 10 based on 5G communication, for example, as shown in fig. 1, the signal transmission apparatus 10 may include a cradle head 100 and a signal transmission device 200, where the cradle head 100 and the signal transmission device 200 are fixedly connected.
Wherein, cloud platform is including possessing the support equipment of installation, fixed and rotation effect. That is, other devices may be mounted on the pan/tilt head so that the pan/tilt head and the other devices are integrated. In addition, the pan-tilt has a rotating function. According to the rotation function of the pan/tilt head, the pan/tilt head can be divided into a horizontal rotation pan/tilt head which can only rotate left and right and an omnidirectional pan/tilt head which can rotate left and right (also called horizontal rotation) and up and down (also called vertical rotation).

In an embodiment, as shown in fig. 1, a directional antenna 201 is disposed on the signal transmission apparatus 200, and the signal transmission apparatus 200 may perform signal transmission through the directional antenna 201 and a 5G base station.
The signal transmission device 200 includes a device capable of performing signal transmission with a 5G base station.
For example, the signal transmission device 200 may include a gateway, a router, or a wireless local area network access point, etc., which employs the directional antenna 201 and a 5G base station for signal transmission.

Here, the directional antenna 201 radiates in a certain angle range in a horizontal directional pattern, that is, the radiation range of the directional antenna has directivity. For example, fig. 2 is a signal radiation diagram of a directional antenna in a horizontal direction, and it can be seen from fig. 2 that the radiation range of the directional antenna has directivity. Because the directional antenna is generally applied to remote communication in a communication system, the coverage area is small, the target density is large, and the frequency utilization rate is high, the directional antenna is generally adopted in equipment which needs to perform signal transmission with a 5G base station in the application field of the Internet of things.

At this time, signals which need to be transmitted by the industrial devices can be sent to the signal transmission device 200, sent to the 5G base station through the signal transmission device 200, and sent to other industrial devices by the 5G base station, so that the interconnection of everything is realized.

In an embodiment, when the signal transmission device 200 detects that the data amount interacting with the 5G base station is less than the preset data amount, it indicates that there is an abnormality in the signal transmission process between the signal transmission device 200 and the 5G base station. At this time, the signal transmission device 200 may send a control signal to the rotating apparatus 103 of the pan/tilt head 100, so that the rotating apparatus 103 rotates through the control signal and drives the signal transmission device 200 to rotate through the fixing structure 102, thereby adjusting the radiation angle of the directional antenna 201.
Wherein the predetermined data amount may be a data amount transmitted per unit time. For example, this preset data amount may be set to zero data amount transmitted per unit time, and so on.
In one embodiment, as shown in fig. 5, the rotation device 103 may include a rotation controller 1001 and a rotation structure 1002. The rotation controller 1001 is electrically connected to the rotation structure 1002. The rotating structure 1002 is movably connected with the holder body 101 and fixedly connected with the fixed structure 102.
The rotation controller 1001 receives a control signal sent by the signal transmission device 200, and controls the rotation structure 1002 to rotate through the control signal, so that the rotation structure 1002 drives the signal transmission device 200 to rotate through the fixed structure 102.
In one embodiment, the rotating structure 1002 may include a first driving motor, a second driving motor, a ring gear, and a spur gear. The first driving motor and the second driving motor are electrically connected with the rotation control submodule respectively. The first drive motor engages the annular internal gear to rotate the rotary structure horizontally. The second driving motor is engaged with the spur gear to vertically rotate the rotary structure.
In an embodiment, as shown in fig. 6 and 11, the rotation controller 1001 may include a signal receiving circuit 1003, a control signal converting circuit 1004, and a rotation control circuit 1005.
The signal receiving circuit 1003 is electrically connected to the control signal converting circuit 1004. The control signal conversion circuit 1004 is electrically connected to the rotation control circuit 1005. The rotation control circuit 1005 is electrically connected to the first driving motor and the second driving motor, respectively.
Among them, the signal receiving circuit 1003 receives the control signal transmitted by the signal transmitting circuit 2006 of the signal transmission apparatus 200, and transmits the control signal to the control signal converting circuit 1004. The control signal conversion circuit 1004 converts the control signal into a rotation signal, and transmits the rotation signal to the rotation control circuit 1005. The rotation control circuit 1005 controls the first drive motor or the second drive motor to rotate in accordance with the rotation signal.
In an embodiment, the control signal may include a signal for triggering the rotation controller 1001 to perform rotation control on the rotating structure 1002, wherein the control signal also carries the pan/tilt adjustment information. The control signal may be an electrical signal, an electromagnetic wave signal, or the like.
Wherein the rotation signal comprises a signal that the rotation control circuit 1005 can recognize and can control the rotation of the rotating structure 1002 according to the rotation signal. Typically, the rotation signal is an electrical signal.
In general, the signal formats of the control signal and the rotation signal are generally different. For example, the control signal is generally an analog signal, and the rotation signal is a digital signal, so the control signal conversion circuit 1004 is required to convert the control signal into the rotation signal, so that the rotation control circuit 1005 controls the rotation structure 1002 according to the rotation signal.
In one embodiment, as shown in fig. 7 and 8, the signal transmission device 200 includes a directional antenna 201, a housing 202, a power measurer 2002, a pan-tilt controller 2001, and a signal transmitter 2003.
Wherein, the housing 202 is fixedly connected with the directional antenna 201. The directional antenna 201 may be fixedly connected to an outer surface of the housing 202, or may be fixedly connected to an inner surface of the housing 202. For example, as shown in fig. 7, the directional antenna 201 is fixedly attached to the outer surface of the housing 202. Wherein the housing 202 may be made of a conductive material.
Among them, the power measurer 2002, the pan/tilt head controller 2001, and the signal transmitter 2003 may be provided inside the housing 202.
As shown in fig. 8, the power measurer 2002 is electrically connected to the signal transmitter 2003 and the pan/tilt controller 2001, respectively.
Wherein the signal transmitter 2003 is used for signal transmission with the 5G base station. Specifically, the signal transmitter 2003 performs signal transmission with the 5G base station through the directional antenna 201. The signal transmitter 2003 may transmit signals through the housing 202 to the directional antenna 201 such that the signals are transmitted to the 5G base station through the directional antenna 201. Furthermore, the signal transmitter 2003 may also receive data transmitted by the 5G base station via the directional antenna 201.
Further, when the signal transmitter 2003 detects that the amount of data interacting with the 5G base station is lower than the preset amount of data, the signal transmitter 2003 may further generate and transmit a power measurement signal to the power measurer 2002, so that the power measurer 2002 measures the signal reception power of the 5G base station according to the power measurement signal.
A power measurer 2002 is used to measure the signal reception power of the 5G base station. When the data amount of the signal transmitter 2003 interacting with the 5G base station is lower than the preset data amount, the power measurer 2002 may receive the power measurement signal generated by the signal transmitter 2003, and measure the signal reception power of the 5G base station according to the power trigger signal. Then, the power measurer 2002 may transmit the measured signal reception power to the pan/tilt controller 2001.
Among them, since power measurement device 2002 is developed according to the received signal power measurement protocol in the 5G communication protocol, power measurement device 2002 can measure the received signal power of the 5G base station according to the received signal power measurement protocol.
The pan/tilt controller 2001 is configured to generate a control signal according to the signal receiving power value, and send the control signal to the rotation controller 1001 of the pan/tilt 100, so that the rotation controller 1001 performs rotation control on the rotation structure 1002 according to the control signal.
In one embodiment, as shown in fig. 9 and 11, the pan/tilt controller 2001 includes a power processing circuit 2004, a pan/tilt control circuit 2005, and a signal transmission circuit 2006.
The pan/tilt/zoom control circuit 2005 is electrically connected to the power processing circuit 2004 and the signal transmitting circuit 2006, respectively.
The power processing circuit 2004 is electrically connected to the power measurer 2002 and the signal transmitter 2003, respectively.
The power processing circuit 2004 is configured to receive the signal received power transmitted by the power measurer 2002, and generate a signal received power mapping signal or a signal transmission trigger signal according to the signal received power. When the power processing circuit 2004 generates the signal reception power mapping signal, the signal reception power mapping signal may be transmitted to the pan/tilt head control circuit 2005. And when the power processing circuit 2004 generates the signal transmission trigger signal, the signal transmission trigger signal may be transmitted to the signal transmitter 2003.
Specifically, after receiving the signal reception power transmitted by the power measurer 2002, the power processing circuit 2004 may compare the signal reception power with a preset signal reception power value.
When the power processing circuit 2004 identifies that the signal receiving power is smaller than the preset signal receiving power value, the power processing circuit 2004 may generate a signal receiving power mapping signal and transmit the signal receiving power mapping signal to the pan/tilt control circuit 2005, so that the pan/tilt control circuit 2005 controls the pan/tilt according to the signal receiving power mapping signal.
When the power processing circuit 2004 recognizes that the signal receiving power is greater than or equal to the preset signal receiving power value, the power processing circuit 2004 may generate a signal transmission trigger signal and transmit the signal transmission trigger signal to the signal transmitter 2003, so that the signal transmitter 2003 continues signal transmission with the 5G base station according to the signal transmission trigger signal.
The signal received power map signal includes a signal carrying the signal received power information of the 5G base station measured by the power measurer 2002. For example, the signal received power mapping signal may be a signal carrying the signal received power value. For another example, the signal received power mapping signal may be a signal carrying a difference between the signal received power value and a preset signal received power value, and the like.
The signal transmission trigger signal includes a signal carrying information for signal transmission by the trigger signal transmitter 2003 and the 5G base station.
The cradle head control circuit 2005 is configured to receive the signal reception power mapping signal transmitted by the power processing circuit 2004, generate a control signal according to the signal reception power mapping signal, and transmit the control signal to the signal transmitting circuit 2006, so that the signal transmitting circuit 2006 transmits the control signal to the signal receiving circuit 1003 of the rotation controller of the cradle head 100.
In an embodiment, the pan/tilt control circuit 2005 may control whether the rotation device 103 performs horizontal rotation or vertical rotation according to the signal transmission power mapping signal; when the rotating device 103 rotates horizontally, it rotates horizontally to the right or to the left; and how many degrees the rotary device 103 rotates horizontally to the right, and so on.
For example, the pan/tilt control circuit 2005 may generate a control signal carrying pan/tilt adjustment information according to the signal reception power mapping signal after receiving the signal reception power mapping signal. The pan/tilt adjustment information includes information for controlling the rotation device 103 to rotate.
In one embodiment, the communication between the signal sending circuit 2006 and the signal receiving circuit 1003 may be various. For example, the signal transmitting circuit 2006 and the signal receiving circuit 1003 may be in wired communication or in wireless communication.
When wireless communication is performed between the signal transmitting circuit 2006 and the signal receiving circuit 1003, bluetooth communication may be performed between the signal transmitting circuit 2006 and the signal receiving circuit 1003, WIFI communication may also be performed, and the like.
For example, as shown in fig. 10 and 11, when bluetooth communication is performed between the signal transmitting circuit 2006 and the signal receiving circuit 1003, the signal transmitting circuit 2006 may include a second bluetooth module 2007, and the signal receiving circuit 1003 may include a first bluetooth module 1006. The first bluetooth module 1006 is electrically connected to the control signal conversion circuit 1004, and the second bluetooth module 2007 is electrically connected to the cradle head control circuit 2005. The second bluetooth module 2007 receives the control signal transmitted by the pan/tilt control circuit 2005 and sends the control signal to the first bluetooth module 1006; the first bluetooth module 1006 receives the control signal and transmits the control signal to the control signal conversion circuit 1004.
For another example, when WIFI communication is performed between the signal transmitting circuit 2006 and the signal receiving circuit 1003, the signal transmitting circuit 2006 may include a second WIFI module, and the signal receiving circuit 1003 may include a first WIFI module. The first WIFI module is electrically connected to the control signal conversion circuit 1004, and the second WIFI module is electrically connected to the pan/tilt control circuit 2005. And the first WIFI module receives the control signal sent by the second WIFI module.
For another example, the signal transmission circuit 2006 may include a second bluetooth module and a second WIFI module. And the signal receiving circuit 1003 includes a first bluetooth module and a first WIFI module. The first bluetooth module is electrically connected to the control signal conversion circuit 1004, and the second bluetooth module 2007 is electrically connected to the pan/tilt head control circuit 2005. The first WIFI module is electrically connected to the control signal conversion circuit 1004, and the second WIFI module is electrically connected to the pan/tilt control circuit 2005. So that the signal transmitting circuit 2006 and the signal receiving circuit 1003 can communicate with each other through both bluetooth and WIFI.
In an embodiment, in order to improve the degree of automation and the degree of intelligence of the signal transmission device 10, the signal transmission device 200 may further include a sensor and a sensor information receiving module. The sensor and the sensor information receiving module are electrically connected to the housing 202, respectively, and the sensor information receiving module are electrically connected to each other. The sensor information receiving module is electrically connected to the signal transmitting circuit 2006.
The sensors are used for monitoring the surrounding environment when the cradle head 100 drives the signal transmission device 200 to rotate. And the sensor information receiving module is used for analyzing the information monitored by the sensor, thereby judging whether an obstacle exists and whether the signal transmission device 200 collides with the obstacle when rotating.
When it is monitored that the angle of rotation of the cradle head 100 may cause the signal transmission device 200 to collide with an obstacle, the sensor information receiving module may generate a rotation stop signal and transmit the rotation stop signal to the signal transmitting circuit 2006, so that the signal transmitting circuit 2006 transmits the rotation stop signal to the signal receiving circuit 1003 of the cradle head 100.
After the signal receiving circuit 1003 of the cradle head 100 receives the rotation stop signal, the rotation will be stopped, so as to avoid collision between the signal transmission device 10 and an obstacle, thereby protecting the data transmission device 10.
In addition, although not shown, the signal transmission device 200 and the pan/tilt head 100 in the present embodiment further include a power supply module and a memory.

Wherein, the cradle head 100 is fixedly connected with the signal transmission equipment 200; the signal transmission apparatus 200 is provided with a directional antenna 201 that transmits and receives signals; the signal transmission apparatus 200 exchanges data with the 5G base station through the directional antenna 201. When the signal transmission device 200 detects that the data volume of the interaction with the 5G base station is smaller than the preset data volume, the signal transmission device 200 sends a control signal to the cradle head 100, and the cradle head 100 drives the signal transmission device 200 to rotate according to the control signal, so as to adjust the radiation angle of the directional antenna 201. By the signal transmission device 10, when the signal transmission equipment 200 detects that the process of interactive signal transmission with the 5G base station is abnormal, the radiation angle of the directional antenna 201 on the signal transmission equipment 200 can be automatically adjusted by the signal transmission device 10, so that the efficiency of signal transmission is improved.
In order to better implement the signal transmission device 10 provided in the embodiment of the present application, a signal transmission system based on 5G communication is also provided in the embodiment of the present application, as shown in fig. 12. The signal transmission system includes a 5G base station 20 and a signal transmission device 10.
The signal transmission device 10 includes a pan/tilt head 100 and a signal transmission apparatus 200. Wherein, the cradle head 100 is fixedly connected with the signal transmission equipment 200; the signal transmission apparatus 200 is provided with a directional antenna 201 that transmits and receives signals; the signal transmission apparatus 200 exchanges data with the 5G base station 20 through the directional antenna 201.
In one embodiment, the 5G base station 20 also utilizes the directional antenna 201 to perform signal transmission with the signal transmission apparatus 200. For example, as shown in fig. 12, each 5G base station 20 directional antenna has a certain radiation angle 40.
As shown in fig. 12, since the original radiation angle 30 of the directional antenna of the signal transmission device 200 and the radiation angle 40 of the directional antenna of the 5G base station 20 are deviated, the amount of data exchanged between the signal transmission device 200 and the 5G base station 20 is smaller than the preset amount of data.
When the interactive data volume of the signal transmission device 200 and the 5G base station 20 is smaller than the preset data volume, the signal transmission device 200 may send a control signal to the cradle head 100, so that the cradle head 100 drives the signal transmission device 200 to rotate according to the control signal, thereby adjusting the radiation angle of the directional antenna 201 of the signal transmission device 200 until the radiation angle 50 of the directional antenna 201 of the signal transmission device 200 overlaps with the radiation angle 40 of the directional antenna of the 5G base station 20.
The signal transmission device in the signal transmission system based on 5G communication provided by the embodiment of the application can automatically adjust the radiation angle of the directional antenna on the signal transmission equipment without manual operation, and the efficiency of signal transmission is improved.
