[0056] The integrated data input terminal 1 includes: a number of 5G communication modules 11, a number of mobile inspection terminals, and a number of fixed-point inspection terminals; each of the 5G communication modules 11 is installed on a corresponding mobile inspection terminal or a fixed-point inspection terminal, and the mobile inspection terminal and the fixed-point inspection terminal can use the installed 5G communication module 11 to send the surveillance video they shoot to the server and the storage terminal 2 at the same time, and each of the mobile inspection terminal and the fixed-point inspection terminal can receive the command signal sent by the server and the storage terminal 2. Among them, the mobile inspection terminal and the fixed-point inspection terminal are cameras for power inspection, and the content of the transmission signal of the mobile inspection terminal and the fixed-point inspection terminal includes the surveillance video.
[0057] like Figure 2As shown, each of the 5G communication modules 11 includes: a radio frequency front end 12, a baseband processor 13, a storage unit 14, and a power management unit 15. The radio frequency front end 12 is connected to the server and the storage end 2 by signals, and can send radio frequency signals to the server and the storage end 2 through the 5G channel, and receive command signals transmitted through the 5G channel. The baseband processor 13 is respectively connected to the radio frequency front end 12 and the corresponding mobile inspection terminal or fixed-point inspection terminal, and can transmit the monitoring video of the digital signal shot by the mobile inspection terminal or the fixed-point inspection terminal, and can convert the digital signal into an analog signal and transmit it to the radio frequency front end 12, or convert the command signal of the analog signal received by the radio frequency front end 12 into a digital signal, complete the modulation and demodulation of the signal, and improve the spectrum efficiency and data transmission rate; and can improve the robustness of the signal and reduce the bit error rate by adding redundant information and using channel coding; the baseband processor 13 extracts useful information from the command signal received by the radio frequency front end 12 and completes decoding; at the same time, it can synchronously process the transmission signal and the command signal to achieve consistent information data exchange. The storage unit 14 is connected to the baseband processor 13 by signals, and includes: a random access memory and a flash memory. The random access memory can directly exchange data with the baseband processor 13 and is used to store temporary data of the running program; the flash memory is used to store the programs and data required to be called by the 5G communication module 11. The power management unit 15 is connected to the RF front end 12, the baseband processor 13, and the storage unit 14, and can provide a stable and efficient power supply for the RF front end 12, the baseband processor 13, and the storage unit 14 in the 5G communication module 11, and manage the battery charging and discharging process of the mobile inspection terminal and the fixed-point inspection terminal.
[0058] Furthermore, the RF front end 12 includes: a power amplifier, an oscillator, a phase locked loop (PPL), a low noise amplifier, a filter, a duplexer, and an antenna switch. The phase locked loop is connected to the baseband processor 13, and can stabilize the phase difference between the transmission signal and the interference signal. The oscillator is connected to the phase locked loop, and can convert the transmission signal from a low frequency signal to a high frequency signal, and improve the stability and transmission rate of the long-distance transmission of the transmission signal through the high frequency band transmission technology. The power amplifier is connected to the oscillator, and can amplify the high-frequency transmission signal. The low noise amplifier is connected to the baseband processor 13, and can reduce the signal-to-noise ratio of the received command signal, and transmit the processed command signal to the baseband processor 13. The filter is connected to the low noise amplifier, and can separate the different frequency components in the received command signal, further extract useful signals from the command signal in the low noise amplifier, and improve the quality or characteristics of the signal. The duplexer is connected to the power amplifier and the low noise amplifier, and can isolate the transmission signal and the command signal, so that the RF front end 12 can send the transmission signal and receive the command signal at the same time. The antenna switch is connected to the duplexer, and can send high-frequency transmission signals and receive command signals through the same antenna, and can switch frequency bands and receiving and sending states.
[0059] After the mobile inspection terminal or the fixed-point inspection terminal captures the surveillance video in real time, the surveillance video is transmitted to the baseband processor 13 of the 5G communication module 11 in the form of a digital signal. The baseband processor 13 converts the digital signal into an analog signal, and transmits the analog signal to the phase-locked loop. The limit locking loop fixes the phase difference between the transmission signal and the interference signal, and transmits the transmission signal to the oscillator at the same time; the oscillator converts the transmission signal from a low-frequency signal to a high-frequency signal, and transmits the high-frequency transmission signal to the power amplifier; the power amplifier amplifies the high-frequency transmission signal, and transmits the amplified transmission signal to the duplexer, and then to the antenna switch. At this time, the antenna switch is in the sending state, and the high-frequency transmission signal is sent through the 5G channel.
[0060] When the antenna switch receives the command signal, the antenna switch switches to the receiving state, and can receive the command signal through the 5G channel, and transmit the command signal to the duplexer, and use the duplexer to isolate the command signal from the transmission signal, and transmit the command signal to the low-noise amplifier and filter, reduce the noise and separate the command signal, improve the strength of the key frequency band in the command signal, and transmit the processed command signal to the baseband processor 13; the baseband processor 13 converts the command signal from an analog signal to a digital signal, and at the same time, synchronously processes the command signal and the transmission signal, and transmits the command signal to the mobile inspection terminal and the fixed-point inspection terminal for execution. In the process of sending the transmission signal and receiving the command signal, the processing program and data required to be called are stored in the storage unit 14, and the power management unit 15 supplies power to each component.
[0061] The server and storage end 2 can receive the transmission signal sent by the integrated data input end 1 through the 5G channel, process the transmission signal and forward it to the mobile application end 3, and can also receive the instruction information sent by the mobile application end 3 through the network and forward it to the integrated data input end 1. The server and storage end 2 includes: an antenna group, a demodulator, and a network configuration component. The antenna group is arranged on the server and storage end 2, and can receive the high-frequency transmission signal sent by the integrated data input end 1, and can send the instruction signal to the integrated data input end 1. The demodulator is connected to the antenna group, and converts the transmission signal received by the antenna group from a high-frequency signal to a low-frequency signal. The network configuration component realizes the separation of the 5G channel at the logical level through the network slicing technology, and can classify and manage the instruction signal to improve the utilization efficiency of the 5G channel; the network configuration component includes: a network slice controller and a slice management software, and the slice management software can set the logic of 5G channel division, so that the divided multiple network slices can be customized according to the business requirements required by the mobile application end. The network slice controller can isolate the divided multiple network slices.
[0062] The antenna switches of several 5G communication modules 11 in the integrated data input terminal 1 can simultaneously send high-frequency transmission signals to the server and storage terminal 2 through the 5G channel, and the antenna group of the server and storage terminal 2 receives multiple groups of high-frequency transmission signals, and transmits the multiple groups of high-frequency transmission signals to the demodulator, which converts the high-frequency signals into low-frequency signals, and forwards the low-frequency transmission signals to the mobile application terminal 3 through the network. The mobile application terminal 3 generates corresponding command signals according to the transmission signals sent by different 5G communication modules 11, and transmits different command signals to the server and storage terminal 2 through the network; the antenna group sends multiple groups of command signals through the 5G channel, classifies the multiple groups of command signals in the 5G channel, and transmits them to the integrated data input terminal 1, and the antenna switch of the integrated data input terminal 1 receives the corresponding command signals. Among them, the network configuration component realizes the classification management of transmission information by dividing the 5G channel, improving the flexibility of 5G channel allocation and the utilization efficiency of 5G channels.
[0063] like Figure 3 As shown, the technologies required to build a 5G channel include: multi-antenna technology, high-frequency band transmission technology, and network slicing technology. The multi-antenna technology requires configuring multiple antennas at the integrated data input terminal 1 and the server and storage terminal 2, respectively. The high-frequency band transmission technology converts the transmission signal from a low-frequency signal to a high-frequency signal by setting an oscillator in the RF front end 12 in the integrated data input terminal 1, and converts the received transmission signal from a high-frequency signal to a low-frequency signal by setting a demodulator in the server and storage terminal 2, thereby realizing high-frequency band transmission of the transmission signal. The slicing network technology utilizes the network configuration components of the server and storage terminal 2 to realize flexible configuration of the 5G channel.
[0064] Further, if Figure 4 As shown, the antenna group includes multiple antennas, and the integrated data input terminal 1 is also configured with multiple antenna switches, that is, the integrated data input terminal 1 is provided with multiple mobile inspection terminals and fixed-point inspection terminals, and the multi-antenna technology is used to expand the coverage of the transmission signal, improve the stability of the link and the transmission rate of the signal; at the same time, the full-duplex MIMO technology is adopted, and the antenna switch of the RF front end 12 can receive and send signals at the same time through the duplexer, which improves the efficiency and real-time performance of data transmission. Through the multi-antenna configuration, the diversity of spatial resources is fully utilized to improve the capacity and spectrum utilization of the centralized monitoring system. Among them, the full-duplex MIMO technology is a combination of MIMO technology and full-duplex technology, and is configured with self-interference elimination technology to eliminate the self-interference problem generated when the antenna sends and receives signals at the same time.
[0065] The self-interference elimination technology includes: antenna interference elimination technology, radio frequency interference elimination technology and digital interference elimination technology. The antenna interference elimination technology reduces the direct coupling between the antenna group and the antenna switch and reduces the self-interference by spacing the installation position of the antenna group from the installation position of the antenna switch in the radio frequency front end 12; at the same time, a number of auxiliary antennas are arranged near the antenna group to generate auxiliary signals with opposite phases to the self-interference signal, and the auxiliary signals and the self-interference signal are used to cancel the self-interference signal.
[0066] The radio frequency interference elimination technology covers the components and lines of the server and storage end 2 and the integrated data input end 1 with a shielding layer to prevent interference signals from affecting the components of 5G signal transmission; the shielding layer is a highly conductive material, usually made of metal materials such as copper and aluminum, and uses metal materials to block the propagation path of electromagnetic waves, thereby achieving a shielding effect. At the same time, an independent auxiliary channel is established in the 5G channel between the server and the storage end 2 and the integrated data input end 1. The auxiliary channel can collect a copy of the interference signal, and an interference signal canceller is configured on the server and the storage end 2 or the integrated data input end 1 to process the copy of the interference signal and generate a cancellation signal with a phase opposite to that of the interference signal, so that the cancellation signal and the interference signal cancel each other to eliminate interference. In a preferred embodiment, a phase-locked loop can be used to fix the phase difference between the interference signal and the received signal within a range, so as to achieve accurate locking of the phase of the interference signal and better eliminate the interference signal.
[0067] The digital interference elimination technology adjusts the weight and phase of the antenna group or antenna switch to point the beam to the desired signal direction, while suppressing interference signals in other directions, and uses digital beamforming technology to process the signal, thereby suppressing the self-interference signal. In a preferred embodiment, the filter of the integrated data input terminal 1 can be used to filter the transmission signal, and the residual self-interference channel can be estimated from the digital domain received signal using the known information of the local transmission signal, and the self-interference signal can be reconstructed and subtracted from the total signal converted by the analog-to-digital converter in the baseband processor 13 to eliminate or weaken the interference signal component.
[0068] like Figure 5 As shown, the network slicing technology uses network configuration components to complete the division of 5G channels, which is used to classify different command signals. The construction steps of the network slicing technology include:
[0069] Step 1: Demand analysis. Collect the specific requirements of mobile applications for network slicing, including service types, performance requirements, and security requirements, analyze the collected requirements, determine the network resources, service levels, protocol requirements, and security policies required for each network slice, and design the architecture, network functions, and configuration parameters of each network slice based on the demand analysis results.
[0070] Step 2: Resource allocation. Evaluate the availability and performance of 5G channels, including bandwidth, computing power, and storage resources. According to the design of each network slice in step 1, formulate a resource allocation strategy, allocate 5G channels to each network slice on demand, and dynamically adjust network slice resource allocation according to changes in business needs to ensure efficient resource utilization and business continuity.
[0071] Step 3: Slice deployment. Create a network slice based on the network configuration components in the server and storage end 2, and use the slice management software to configure network functions and security policies, including configuring the subnets within the network slice and network devices that support the slicing function, to ensure that the network devices can forward and process data according to the network slice requirements. The network devices include: server and storage end 2, integrated data input end 1.
[0072] Step 4: Network slicing test. Test whether the network slice meets the business needs of the mobile application end. The test content includes: the transmission performance of the network slice, the security performance of the network slice, data transmission, signaling transmission and resource scheduling. Among them, the transmission performance indicators of the slice include: bandwidth utilization, delay, packet loss rate, etc., to ensure that the slice performance meets the service level agreement (SLA) requirements; the security performance of the network slice includes: data isolation, access control and encrypted transmission to ensure data security between slices; the data transmission is used to ensure that the transmission signal and the command signal can be transmitted between the server and the storage end 2 and the integrated data input end 1; the signaling transmission is used to coordinate and control the signal connection process to ensure the smooth progress of the signal transmission.
[0073] Step 5: Network slicing online. After the network slice passes the test in step 4, prepare the relevant documents, configuration scripts and monitoring tools for the network slice online, put the network slice into operation, and use the monitoring tools to continuously monitor the network slice, collect operation data, analyze the performance of the network slice, and adjust and optimize resources according to changes in business needs. Complete the verification experiment of the network slice and officially put the verified network slice into operation.
[0074] To summarize, the present invention installs 5G modules on mobile inspection terminals and fixed-point inspection terminals, and utilizes multi-antenna technology, high-frequency band transmission technology, and network slicing technology to construct a 5G channel between an integrated data input terminal and a server and a storage terminal, so as to enable multiple mobile inspection terminals and fixed-point inspection terminals to simultaneously transmit monitoring videos and simultaneously receive command signals sent by a mobile application terminal; at the same time, full-duplex MIMO technology is used in multi-antenna technology to realize the simultaneous transmission of transmission signals and command signals, and self-interference elimination technology is used to eliminate the self-interference problem caused by the antenna sending and receiving signals at the same time.
