Abstract
Description
Technical Field
[0001] This utility model relates to a high-speed multi-channel self-organizing network device and system. Background Technology
[0002] Traditional ad hoc network devices have complex hardware architectures, relying on multi-chip collaboration for protocol processing and signal modulation. This results in bulky devices with high power consumption, making them unsuitable for the portability requirements of mobile emergency scenarios. Existing radio frequency units mostly employ a dual-channel transceiver design, resulting in low channel isolation, limited signal coverage, and a lack of modular expansion capabilities, making rapid repair or upgrades via hot-swapping impossible. Antenna units are mostly configured with fixed frequency bands, which can easily lead to signal dead zones in complex terrain or electromagnetic interference environments, affecting communication stability.
[0003] Furthermore, the existing equipment's interface protocol parsing and data processing modules are separated, resulting in low efficiency and cumbersome deployment processes when multiple types of services are running concurrently. For example, the lack of integrated plug-and-play interfaces requires complex configuration for external terminals to connect, and the chassis design does not consider human-computer interaction. Frequency switching and group management rely on software operations, making it difficult to meet the rapid response needs of scenarios such as fire fighting and public security.

[0021] Figure 2 This is a schematic diagram of a high-speed multi-channel self-organizing network system provided by this utility model. Detailed Implementation
[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] This application provides a high-speed multi-channel self-organizing network device with strong anti-interference capability, realizing high-speed, low bit error rate communication under large-scale dynamic networking, supporting flexible cross-group collaboration, and significantly improving communication stability and efficiency in complex environments.
[0024] like Figure 1 The high-speed multi-channel self-organizing network device shown includes:
[0025] The local data processing unit is equipped with multiple external interfaces, which are used to collect data from multiple sources.
[0026] A digital signal processing unit is connected to a local data processing unit; the digital signal processing unit integrates a group management hardware circuit; the group management hardware circuit is used to generate a level signal representing a group identifier; the digital signal processing unit is used to process the multi-source data and the level signal to generate a digital signal.
[0027] A multi-channel radio frequency unit includes a radio frequency transceiver chip, a receiving channel, and a transmitting channel. The radio frequency transceiver chip is used to convert digital signals into radio frequency signals at a preset frequency.
[0028] The antenna unit includes a multi-channel transceiver antenna, which is connected to the receiving / transmitting channel of the multi-channel radio frequency unit and is used to transmit and receive radio frequency signals.
[0029] The external interfaces of the local data unit are used to acquire data from multiple sources. These external interfaces include, but are not limited to: a Wi-Fi interface, an RJ45 interface, a voice interface, and a message interface. The Wi-Fi interface is for all types of terminal devices with Wi-Fi capabilities; the RJ45 interface is for all types of terminal devices accessing the network via Ethernet; the voice interface is for devices such as microphones and headsets; and the message interface is for terminal devices with RS485 interfaces or digital I / O ports.
[0030] After acquiring multi-source data, it is framed and parsed using a first different interface protocol, and then processed. After extracting the data according to the corresponding interface protocol, the data is aggregated, framed, and transmitted to the digital signal processing unit.
[0031] The digital signal processing unit comprises ten parts, including second different interface protocol parsing, subcarrier data framing, COFDM modulation, parallel-to-serial conversion, second different interface protocol framing, subcarrier data parsing, COFDM demodulation, serial-to-parallel conversion, current operating frequency setting, and group setting components, and is implemented using a single FPGA.
[0032] The second different interface protocol framing of the digital signal processing unit parses and classifies the multi-source data, and then enters the subcarrier data framing. Each subcarrier uses a different modulation scheme for data processing according to its own data rate. In specific implementations, the modulation scheme of each subcarrier can be BPSK, 16QAM, 64QAM, 128QAM, 1024QAM, 4096QAM, etc.
[0033] After the subcarrier data from the digital signal processing unit is framed, the data undergoes multi-carrier COFDM modulation and then parallel-to-serial conversion. This converts the parallel data into high-speed serial data, which is then transmitted to the multi-channel radio frequency unit. Simultaneously, the digital signal processing unit sends its operating frequency information to the multi-channel radio frequency unit; this operating frequency information is determined by the current operating frequency.
[0034] In this application, the digital signal processing unit is implemented using an FPGA device or a DSP device. Preferably, the FPGA device is a Xilinx XC7Zxx series, but Fudan Microelectronics' FMKxx or FMQLxx series can also be used; the DSP device is a TI TMS320C66xx series, etc.
[0035] The digital signal processing unit is implemented using a single FPGA. The high integration of the single FPGA solves the resource redundancy problem of traditional multi-chip architectures. Traditional solutions rely on a combination of multiple DSPs and CPUs, requiring bus interaction between multiple chips to complete protocol processing and signal modulation, resulting in large hardware size, high power consumption, and significant latency. In contrast, the single FPGA, through the high integration of its internal logic units, integrates functions such as protocol parsing, dynamic subcarrier allocation, COFDM modulation and demodulation, and group management into a single chip, eliminating communication latency between multiple chips, improving data processing efficiency, and reducing node switching time to the millisecond level, significantly meeting the stringent real-time requirements of military, emergency, and other scenarios.
[0036] Meanwhile, multi-service concurrency capabilities are optimized through a single FPGA. The single FPGA operates in parallel through multiple internal logic modules, such as the protocol parsing module and the COFDM modulation module working synchronously. It can allocate independent subcarrier resources to different services simultaneously, realizing parallel scheduling and transmission of multiple services and solving the bandwidth contention problem in traditional solutions when multiple services are concurrent.
[0037] After receiving high-speed serial data and operating frequency information, the multi-channel RF unit first sends the data to the RF transceiver chip, which converts the digital signal into an RF signal for the current operating frequency. The multi-channel RF unit includes both receive and transmit channels, with the number of receive channels exceeding the number of transmit channels.
[0038] Multiple receiving channels can simultaneously capture signal components from different directions through spatial diversity and polarization diversity, suppressing multipath interference and co-channel interference. For example, four receiving channels combined with MIMO technology can separate and enhance effective signals, reducing the bit error rate. More receiving channels can cover a wider receiving angle, capturing weak signals in complex environments such as mountainous areas and densely built-up areas, improving the stability of long-distance communication and enhancing anti-interference capabilities. For example, noise reduction using four independent LNAs (Low Noise Amplifiers) can effectively amplify weak signals. Multiple receiving channels can also scan multiple frequency bands simultaneously, quickly identifying the optimal channel. Combined with FPGA-based dynamic spectrum sensing algorithms, interference frequencies can be avoided in real time, improving spectrum utilization. For example, in military scenarios, enemy interference frequency bands can be dynamically avoided.
[0039] In this application, the multi-channel RF unit includes a first switch, PA1, LNA1, a second switch, a third switch, PA2, LNA2, a fourth switch, LNA3, a fifth switch, LNA4, a sixth switch, and an RF transceiver chip. The first switch, together with PA1, LNA1, and the second switch, forms a first receive / transmit channel; the third switch, together with PA2, LNA2, and the fourth switch, forms a second receive / transmit channel; LNA3 and the fifth switch form a third receive channel; and LNA4 and the sixth switch form a fourth receive channel. The isolation between the transmit and receive channels of the multi-channel RF unit is ≥50dB.
[0040] After the RF transceiver chip converts the digital signal into an RF signal at the current operating frequency, the first, second, third, and fourth switches all switch to the downlink, and the RF signal enters PA1 and PA2 for power amplification, respectively. During operation, the channel signals of PA1 and PA2 are independent of each other, and the signal isolation between the first and second receive / transmit channels is greater than 50 dB. In this application, the RF transceiver chip uses ADI's ADRV90xx series, AD93xx series, or TI's AFE79xx series, etc., and PA1 and PA2 use high-efficiency power amplifier modules. The first, second, third, and fourth switches can use Taihejia's TS80xx series switches.
[0041] The two amplified radio frequency (RF) signals are respectively input into the antenna unit, which includes a first transceiver antenna, a second transceiver antenna, a first receiving antenna, and a second receiving antenna. The first and second transceiver antennas radiate the RF signals to the area to be covered. The multi-channel RF unit and antenna unit are equipped with two transmit channels and four receive channels, and operate in TDD switching mode, with an operating frequency range covering 70MHz-6GHz.
[0042] The data is received by the first transceiver antenna, second transceiver antenna, first receiving antenna, or second receiving antenna of another device located within the coverage area. After reception, the data is recovered through COFDM demodulation and protocol parsing. The radio frequency signal is parsed and recovered, enabling data exchange between two high-speed channel self-organizing networks.
[0043] Furthermore, the first and second transceiver antennas, the first receiving antenna, and the second receiving antenna all employ omnidirectional rubber rod antennas to achieve omnidirectional signal radiation and reception, providing 360-degree coverage without dead zones and ensuring stable communication in complex environments such as dense buildings and mountainous areas. The structure is compact, weather-resistant, and adaptable to the 70MHz-6GHz wide frequency band. Combined with a multi-channel RF unit, it enhances anti-interference capabilities and signal sensitivity, ensuring high-speed data transmission in mobile scenarios.
[0044] In some embodiments, this device can also interact with other devices or form a self-organizing network with other devices, divided into one or more groups. Each group consists of several high-speed multi-channel self-organizing network devices. Self-organizing network devices within a group can communicate with each other, but self-organizing network devices between groups cannot communicate. Group settings are implemented through group management hardware circuitry. The group management hardware circuitry includes physical DIP switches or rotary encoder switches to generate level signals representing group identifiers; each level signal corresponds to a target group. The device body is provided with a group setting input port, which can be a physical DIP switch, rotary encoder switch, or user interface, reducing the probability of erroneous operation; this application does not limit the specific type of input. The group management hardware circuitry improves real-time performance and reliability through hardware structure. This is superior to software processing, avoiding group identifier resolution errors caused by software delays or interruptions, ensuring the device quickly responds to group switching requirements, and is suitable for military, emergency, and other scenarios requiring high real-time performance.
[0045] In this application, the group identifier is set by mechanical toggle, which has strong anti-interference ability. In environments with severe electromagnetic interference, the physical switch is not easily affected by software interruption or signal interference, ensuring the stability of the switching operation; at the same time, the mechanical feedback of the DIP switch reduces the probability of misoperation, and users can confirm the switching is completed by touch, avoiding group identifier errors caused by accidental screen touch or software misjudgment, thus improving the reliability of the device.
[0046] After receiving the level signal representing the group identifier, the digital signal processing unit acquires and parses the target group signal to obtain the target group identifier. By capturing commands sent by the user or host computer, it determines the target group that needs to be accessed, providing a basis for subsequent operations such as frequency synchronization and resource allocation. User-triggered operation is suitable for on-site personnel to quickly adjust groups according to the actual environment, such as firefighters switching to the command group at a rescue site. Host computer-triggered operation, on the other hand, meets the unified scheduling needs of large-scale collaborative scenarios, such as the command center uniformly allocating groups to various units in military exercises, improving the adaptability of this device in different application scenarios.
[0047] The group identifier includes an operating frequency and a group type flag. The operating frequency determines the frequency band on which this device communicates with other nodes, ensuring that all nodes within the same group use the same frequency to transmit signals and avoiding frequency band conflicts. The group type flag is used to distinguish the communication rules of different groups, such as military, emergency, encryption level, modulation method, etc., ensuring that only nodes in the same type of group can exchange data. Through these two key parameters, this device can accurately access the target group and achieve efficient information exchange with other nodes.
[0048] The operating frequency directly determines the transmit / receive frequency of the multi-channel RF unit, ensuring that the device and other nodes within the target group use the same frequency band for signal transmission, avoiding signal incompatibility due to frequency differences. The group type flag corresponds to different modulation methods, such as 4096QAM or BPSK, encryption protocols, and other parameters. By matching these parameters, the device can adjust its signal processing strategy to be fully compatible with the communication rules of the target group. After entering the corresponding network environment, the device officially joins the group, shares subcarrier resources with other nodes, and participates in data interaction, ultimately achieving efficient collaborative communication within the group.
[0049] When this device does not enter the target group, it performs frequency detection to obtain frequency interference information; it determines whether the target group is being interfered with based on the frequency interference information; if interference is received, it abandons joining the target group; if no interference is received, it sets the radio frequency parameters and modulation mode of the target group based on the group identifier.
[0050] Frequency detection is used to actively assess the electromagnetic environment of a target group's operating frequency band. It is achieved through four receiving channels of a multi-channel RF unit, simultaneously scanning multiple sub-bands near the target frequency point to collect data such as signal strength and noise power, thus generating frequency interference information. In complex electromagnetic environments such as high-density buildings or war zones, the target group's operating frequency point may already be occupied by enemy jammers, civilian Wi-Fi devices, or other equipment. If the device is directly connected, signal overlap may cause a surge in bit error rate or even communication interruption.
[0051] By comparing frequency interference information with a preset interference threshold, the device can quickly assess the communication quality risk of a target group. For example, noise power ≥ -80dBm is considered strong interference. If it is determined to be "under interference," the device will abandon joining that group and instead try other candidate groups or trigger a frequency hopping to avoid communication failures caused by interference. If it is determined to be "unaffected," it indicates that the frequency environment of the target group is clean, and the device can safely access it. This judgment mechanism effectively improves the device's anti-interference capability, ensuring that the optimal communication frequency band can be selected even in complex environments, guaranteeing the stable transmission of critical services such as high-definition video and real-time commands.
[0052] After confirming the safety of the operating frequency environment, the device configures its radio frequency unit according to the operating frequency in the group identifier. This includes adjusting the local oscillator frequency of the RF transceiver chip to 5.8 GHz and selecting the corresponding modulation scheme based on the group type identifier; for example, 4096QAM is used for military groups to improve data rate and encrypt parameters. Through this configuration, the device's transmit / receive link is fully synchronized with the target group, and subsequent data transmission will strictly adhere to the group's communication rules, ensuring correct demodulation and parsing of signals from other nodes. This process not only guarantees communication reliability but also maximizes spectrum utilization through dynamic parameter adjustment, meeting the high-speed data transmission requirements of different scenarios.
[0053] After confirming the safety of the operating frequency environment, the device configures its radio frequency unit according to the operating frequency in the group identifier. This includes adjusting the local oscillator frequency of the RF transceiver chip to 5.8 GHz and selecting the corresponding modulation scheme based on the group type identifier, such as using 4096QAM for military groups to improve speed and encryption parameters. Through this configuration, the device can adjust its signal processing strategy to be fully compatible with the communication rules of the target group. The device's transmit / receive link is completely synchronized with the target group, and subsequent data transmission will strictly follow the group's communication rules, ensuring correct demodulation and parsing of signals with other nodes. This not only guarantees communication reliability but also maximizes spectrum utilization through dynamic parameter adjustment, meeting the high-speed data transmission requirements of different scenarios.
[0054] The digital signal processing unit dynamically allocates subcarrier modulation schemes, transmitting radio frequency (RF) signals through an independent transmit channel after COFDM modulation; alternatively, it captures RF signals through a receive channel, recovers the data through COFDM demodulation and protocol parsing. This dynamic allocation of subcarrier modulation schemes optimizes transmission efficiency based on real-time channel quality. When channel quality is good, such as a signal-to-noise ratio (SNR) ≥ 30 dB, high-order modulation such as 4096QAM is used to improve spectrum utilization and transmission rate; when channel quality deteriorates, such as an SNR < 10 dB, it switches to low-order modulation such as BPSK to reduce the bit error rate. This adaptive adjustment mechanism significantly improves communication stability in complex electromagnetic environments.
[0055] COFDM modulation processes multiple subcarrier signals in parallel, using guard intervals to resist multipath fading. It is particularly suitable for scenarios with severe signal reflection, such as densely built-up areas and mountainous regions, ensuring signal integrity during transmission. The independent transmit channels of the multi-channel RF unit are physically isolated to avoid crosstalk, ensuring the independence of the two transmit signals and improving coverage and power efficiency. During reception, the four receive channels capture signals from multiple directions through spatial diversity. COFDM demodulation restores the parallel subcarrier signals to the original data stream, and protocol parsing converts the data into video, voice, and other service streams based on the interface type, ultimately achieving complete recovery from the RF signal to the original data. Through dynamic modulation, multi-carrier processing, and multi-channel collaboration, it maximizes resistance to environmental interference while ensuring transmission speed, meeting the dual requirements of high-speed and reliable communication in scenarios such as military collaboration and emergency rescue.
[0056] After entering a group, this device receives group instructions in real time. If the group instruction meets any of the following conditions, the group switching operation is performed: a remote group change instruction is received; or the preset target group entry information is met.
[0057] The group switching operation includes switching the group identifier via a DIP switch and setting a new frequency point and modulation method based on the new group identifier.
[0058] After joining a group, the device maintains dynamic synchronization with the group to ensure it can promptly perceive changes in the group environment. This allows the device to obtain the latest communication rules or scheduling requirements immediately, avoiding communication failures or coordination breakdowns due to information lag. For example, if the command center sends a "switch to backup group" command, and the device is not listening in real time, it may miss critical instructions, resulting in the inability to receive subsequent operational deployment information. Based on the actual engineering site conditions, the device is divided into multiple groups. Each group consists of several high-speed, multi-channel self-organizing network devices. Devices within a group can communicate with each other, but self-organizing network devices between groups cannot communicate.
[0059] The device performs a switching operation when it receives a remote group change command or meets the preset target group entry information. The remote group change command is sent proactively by the host computer, such as the command center, and is suitable for scenarios requiring unified action, such as multiple units simultaneously adjusting their communication groups during military exercises to ensure all nodes follow the same rules and avoid coordination chaos caused by dispersed groups. The preset target group entry information is automatically triggered by the device based on its own preset rules, such as when the current group signal strength is below a threshold or the number of members in the new group meets the requirements, and is suitable for scenarios requiring autonomous adjustment. Switching groups based on these two conditions significantly improves the device's adaptability in complex environments.
[0060] Group switching operations include changing group identifiers via DIP switches or buttons. The mechanical toggle directly alters the group identifier, offering strong anti-interference capabilities. In environments with severe electromagnetic interference, the physical switch is less susceptible to software interruptions or signal interference, ensuring the stability of the switching operation. Simultaneously, the mechanical feedback of the DIP switch reduces the probability of erroneous operation; users can confirm the switching completion through touch, avoiding group identifier errors caused by accidental screen touches or software misjudgments, thus improving the reliability of the device.
[0061] The new group identifier includes the target group's operating frequency and group type flag. Frequency settings ensure that the device uses the same frequency band to transmit signals as other nodes in the new group, avoiding signal incompatibility due to frequency differences. Simultaneously, the modulation scheme is adjusted according to the new group type, ensuring full compatibility between the device's signal processing strategy and the new group's communication rules. This device can quickly integrate into the new group's network environment, share subcarrier resources with other nodes, and participate in data interaction, ultimately achieving seamless communication after group handover and ensuring the continuity of critical services.
[0062] Furthermore, after entering the network environment corresponding to the target group or completing the group handover operation, the time and frequency, and synchronization parameters are updated via GPS or BeiDou modules. By utilizing the high-precision time and frequency reference provided by the satellite navigation system, the problem of time and frequency asynchrony caused by differences in initial states such as geographical location and clock drift among different nodes is resolved, ensuring that all devices within the group maintain strict time and frequency consistency during communication.
[0063] When a device switches from its original group to a new target group, the nodes in the new group may come from different deployment areas or use different initial clock sources, resulting in potentially greater time-frequency differences. In this case, by updating synchronization parameters via GPS or BeiDou modules, the device can quickly integrate into the new group's time-frequency system, ensuring that the switched device maintains time slot alignment with the new group's nodes during data transmission. Updating the frequency synchronization parameters ensures that the device's transmit / receive frequencies are completely consistent with the new group, avoiding signal demodulation issues caused by frequency deviations. This allows the device to quickly establish reliable communication with the new group's nodes, guaranteeing the continuity of critical services.
[0064] Based on the same inventive idea, such as Figure 2 As shown, this application also provides a high-speed multi-channel ad hoc network system, including at least two high-speed multi-channel ad hoc network devices as described above. Each group consists of several high-speed multi-channel ad hoc network devices. Devices within a group can communicate with each other, but devices between groups cannot communicate. To enable communication between two groups, both groups must use the same operating frequency and be set as the same type of group. When any high-speed multi-channel ad hoc network device needs to change groups, it needs to join according to the agreed frequency and group type information to achieve communication with the ad hoc network devices in the corresponding group.
[0065] This device and system, through its multi-external-interface design of the local data processing unit, achieves compatible access to various data types, including video, voice, and messages, enhancing its adaptability to diverse terminals. The group management hardware circuitry integrated into the digital signal processing unit converts group identifiers into level signals for direct driving, ensuring real-time and reliable group switching and avoiding communication interruptions caused by software delays. The multi-channel radio frequency unit, through the collaboration of radio frequency transceiver chips and independent transceiver channels, achieves efficient conversion between digital signals and preset frequency radio frequency signals, enhancing signal transmission stability in complex electromagnetic environments. The connection design between the multi-channel transceiver antenna and the radio frequency unit, through spatial diversity and omnidirectional coverage characteristics, expands the signal coverage range and ensures communication continuity in mobile scenarios. The collaborative work of each unit significantly improves the device's multi-service support capabilities, group management efficiency, and environmental adaptability, providing reliable self-organizing network communication guarantees for scenarios such as military collaboration and emergency rescue.
[0066] The above descriptions are merely some embodiments of this utility model.
