Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of radio frequency equipment energy saving, and in particular to a radio frequency splitting device and base station equipment. Background Art
[0002] With the construction of 5G networks and the extension of coverage to rural areas, 5G network operators have an increasingly larger proportion in multi-layer networks and are gradually becoming the main network. As a result, a large number of equipment in rural areas and multi-layer network devices consume a lot of energy, which is not conducive to energy conservation and environmental protection.
[0003] At present, energy saving is often achieved through a combination of traditional software and hardware. However, with the increase in 5G users, the network's low-load operation time will decrease, the busy-idle ratio will decrease, sub-frame silence will occur, and power outage duration will be shortened. This will inevitably lead to a decline in energy saving effects, which is not conducive to low-cost operation of the network. At the same time, 5G devices will be powered off during idle time. After the 5G customer penetration rate increases, some users will have a poor experience with the 5G network, which is not conducive to the improvement of network perception. Utility Model Content

DETAILED DESCRIPTION
[0018] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, the following will describe in detail exemplary embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described herein.
[0019] In view of the problem that the existing technology cannot achieve energy saving and network perception by combining traditional software and hardware, this application provides a radio frequency splitting device that can achieve the purpose of energy saving and cost reduction without affecting network perception. Figure 1 2 is a schematic structural diagram illustrating a radio frequency splitting device according to an embodiment of the present disclosure. Figure 2 FIG is a schematic diagram illustrating a detection component of an embodiment of the present disclosure. Figure 1 and Figure 2 As shown, the RF splitting device is applied to RF components and antenna components, and includes a housing 1, a power supply module 2, and a RF splitting unit 3 disposed within the housing 1. The power supply module 2 is electrically connected to the RF splitting unit 3, and the RF splitting unit 3 includes a detection component 301, a control unit 302, and a switch component 303. The detection component 301, the control unit 302, and the switch component 303 are arranged in sequence from top to bottom along the left side of the upper surface of the power supply module 2. The input end of the detection component 301 is electrically connected to the output end of the RF component to detect whether there is power at the output end of the RF component; the output end of the detection component 301 is electrically connected to the input end of the control unit 302, and the output end of the control unit 302 is electrically connected to the input end of the switch component 303 to control the switch component 303 to change the connection state between the switch component 303 and the antenna component; the output end of the switch component 303 is connected to the input end of the antenna component to change the connection state between the switch component 303 and the antenna component, thereby adjusting the connection path between the RF component and the switch component 303.
[0020] It can be understood that the power supply module 2 and the RF splitting unit 3 in the present application are arranged in sequence from the inside to the outside in the shell 1. Therefore, the shell 1 can fix and protect the power supply module 2 and the RF splitting unit 3, so that the probability of failure due to extreme weather during the installation and operation of the RF splitting device in actual scenarios is reduced, and the service life of the power supply module 2 and the RF splitting unit 3 in the RF splitting device is extended. On this basis, the power supply module 2 in the present application can continuously provide the control power demand for the RF splitting unit, thereby ensuring that the RF splitting unit can operate normally. The detection component 301 included in the RF splitting unit 3 is electrically connected to the control unit 302. Therefore, after the detection component 301 obtains the power signal of the output end of the RF component 4 and determines whether there is power at the output end of the RF component 4, the control unit 302 can send a control signal to the switch component 303 electrically connected to it according to the signal, so that the connection state of the switch component 303 and the antenna component is changed. In this process, RF splitting can be achieved without consuming the resources of the network equipment, which is conducive to ensuring the coverage effect of the network, thereby achieving the purpose of energy saving and cost reduction without affecting network perception.
[0021] like Figure 1 and Figure 2 As shown, the detection component 301 in the present application includes a radio frequency circulator 3011, a coupler 3012, and a detector 3013. When the output end of the radio frequency component 4 transmits a power signal to the input end of the radio frequency circulator 3011, the output end of the radio frequency circulator 3011 is electrically connected to the input end of the detector 3013 via the coupler 3012, and the output end of the detector 3013 is electrically connected to the input end of the control unit 302.
[0022] In a specific implementation, when the RF component 4 transmits a power signal to the RF splitting device, it can be transmitted sequentially through the RF circulator 3011 and the coupler 3012 to the input end of the detector 3013. During this process, the RF circulator 3011 can protect the transmission channel of the power signal of the object to be measured. When the signal is idle, due to its certain isolation, it can ensure that the various components in the detection component 301 are not affected to the greatest extent. The coupler 3012 in the detection component 301 can couple the power signal of the RF component 4, and the signal enters the input end of the detector 3013 to determine whether there is power at the output end of the RF component 4. The signal after determination enters the input end of the control unit 302 through the output end of the detector 3013.
[0023] In actual applications, the RF component is electrically connected to the antenna component through the RF splitting device. Therefore, the present application can use the RF splitting device to obtain a signal indicating whether there is power at the output end of the RF component. The control unit can then control the switch component based on the signal, thereby adjusting the connection status with each part of the antenna component based on the control signal, thereby achieving RF splitting. In this process, the connection relationship between the RF component and the antenna can be automatically changed according to the number of RF components actually activated, reducing the number of RF components used in the base station while ensuring a certain network coverage effect, thereby achieving the purpose of energy saving and cost reduction without affecting network perception.
[0024] Figure 3 FIG is a schematic diagram illustrating the connection between the control unit and the switch assembly of the embodiment of the present disclosure. Figures 1 to 3 As shown, the switch component 303 in the present application includes an amplifier 3031 and a switch 3032, wherein the input end of the control unit 302 is electrically connected to the output end of the detector 3013. Therefore, after the detector 3013 outputs a signal indicating whether there is power at the output end of the RF component 4 to the input end of the control unit 302, the control unit 302 can convert a control signal according to the signal, and the control signal enters the input end of the switch 3032 through the amplifier 3031. The output end of the switch 3032 is electrically connected to the input end of the antenna component 5. Therefore, the switch 3032 can adjust its connection direction with the antenna component 5 according to the control signal, thereby achieving the purpose of adjusting the connection path between the RF component 4 and the antenna component 5.
[0025] Among them, after the detector 3013 outputs the signal whether there is power at the output end of the RF component 4 to the input end of the control unit 302, when the signal of power is detected, the connection relationship in two directions or three directions can be changed according to actual needs.
[0026] For example, if there are three cells in operation and three RF modules, and the third RF module port is transmitting at full power, the first and second RF modules are transmitting at no power, and the cell is operating normally, you can adjust the switch connection status to connect the third RF module port to the antenna modules where the remaining two RF modules are located.
[0027] In an alternative approach, such as Figures 1 to 3As shown, the RF splitting unit 3 in the present application further includes a monitoring and display component 304, which is provided on the right side of the upper surface of the power supply module 2. The switch component 303 and the power supply module 2 are electrically connected to the monitoring and display component 304. Therefore, when the connection relationship between the switch component 303 and the antenna component 5 is switched or transferred, the electrical signal can be transmitted to the input end of the monitoring and display component 304, so that the connection status of the switch component 303 can be monitored and displayed, and the connection path between the RF component 4 and the antenna component 5 is made clearer.
[0028] In actual applications, the distance between the logged-in customer and the base station can be located based on the network background big data, and the time period within which the customer coverage distance is within 80% of the base station can be selected for configuration, and the antenna connection relationship and power-off of each base station can be automatically scripted. After the configuration takes effect, the detection component detects whether there is power in each RF component, and switches or converts the connection relationship between the RF component and the antenna component based on the signal. The monitoring and display component used in this application may include a solar electric control box and a narrowband cellular Internet of Things control unit provided in the electric control box, which can realize remote status monitoring of the switch component and display of the connection status based on the narrowband cellular Internet of Things network technology.
[0029] For example, if there are three RF components and the detector component detects that the second RF component is powered off and there is no power interface, the switch component, under the control of the control unit, connects the first RF component to the antenna component corresponding to the second RF component. During this process, the monitoring and display component can remotely monitor the status of the switch component and display the connection status. When the connection status of the second RF component needs to be restored, the detector component transmits a corresponding electrical signal to the control unit based on the detection result. The control unit then controls the switch component based on the electrical signal to restore the connection between the antenna and the second RF component. At the same time, the switch component can transmit the corresponding electrical signal to the monitoring and display component to update the status.
[0030] Another example: the number of RF components is 3. When the detection component detects that the third RF component is powered off and there is no power interface, the detection component transmits a corresponding electrical signal to the control unit according to the detection result, and the control unit controls the switch component to connect the first RF component with the antenna component corresponding to the third RF component according to the electrical signal. During this process, the monitoring and display component can realize remote status monitoring and connection status display of the switch component. When the connection status of the second RF component needs to be restored, the detection component transmits a corresponding electrical signal to the control unit according to the detection result, and the control unit controls the switch component to restore the connection relationship between the antenna and the second RF component according to the electrical signal. At the same time, the switch component can transmit the corresponding electrical signal to the monitoring and display component to update the status.
[0031] In an alternative approach, such as Figures 1 to 3 As shown, the RF splitting unit 3 in the present application further includes an alarm unit 305, which is provided on the outer surface of the housing 1 and is electrically connected to the monitoring and display assembly 304. Therefore, when the monitoring and display assembly 304 detects a fault in a component within the switch assembly 303, it can transmit a fault signal to the alarm unit 305 to perform an alarm operation, thereby providing timely alarm feedback to the staff, ensuring that the fault problem of the RF splitting device can be resolved as soon as possible, thereby greatly reducing the impact of the RF splitting device on the user's network perception.
[0032] In an optional embodiment, the power supply module in the present application is a solar power supply module. The solar power supply module is easy to install, has low operating costs and maintenance costs, can operate normally in an unattended environment for a long time, has high photoelectric conversion efficiency, is strong in low light conditions, and can be used outdoors in a place with direct sunlight.
[0033] In one optional embodiment, the housing in the present application is a stainless steel housing. This stainless steel housing can be used in extreme weather conditions, reducing the probability of failure due to extreme weather conditions and extending the service life of the power supply module and RF splitting unit in the RF splitting device, thereby ensuring its safe installation and normal use on the antenna support.
[0034] This application also provides a base station device, Figure 4 Schematic diagram of a base station device according to an embodiment of the present disclosure. Figure 4 As shown, the base station device includes a radio frequency component 4, an antenna component 5, and the aforementioned radio frequency splitting device. The radio frequency component 4 is electrically connected to the antenna component 5 via the radio frequency splitting device. Specifically, the detection component 301 and the control unit 302 are sequentially connected in series between the output of the radio frequency component 4 and the input of the switch component 303; the output of the switch component 303 is connected to the input of the antenna component 5. The benefits of this are similar to those of the aforementioned radio frequency splitting device and are not further elaborated here.
