Description

Technical Field

[0001] The present invention relates to the technical field of wireless detection, identification and transmission, and in particular to a wireless beam transmission method based on active controllable absorption / attenuation and related equipment. Background Art

[0002] Wireless beam transmission is the core of modern communication, detection and identification systems, which is specifically manifested in related supporting equipment such as radar, wireless base stations, and wireless charging equipment. Its target is the rapidly developing and changing wireless transmission products. The working efficiency of wireless beam transmission is particularly important for the detection range, recognition efficiency, resolution, working efficiency, information, energy transmission capability, and anti-interference of radar / wireless base stations / wireless energy transmission and other equipment. For equipment in a complex CNI (communication, navigation, identification) electromagnetic signal environment, it is very important for the normal function operation and working efficiency, which is specifically reflected in the rapid identification of complex electromagnetic environments, the rapid manifestation of related anti-interference capabilities, and the improvement of wireless transmission efficiency. In order to adapt to the relevant capabilities in a complex electromagnetic environment, how to achieve the dynamic adaptability of related components, the rapid response to environmental interference, and the improvement of transmission efficiency and power consumption are the key.

[0003] At present, radar / wireless base station / wireless energy transmission equipment often has a special electromagnetic environment and the sidelobe clutter effect of wireless beam transmission, which leads to high overall power of the equipment, low wireless transmission efficiency, and poor anti-interference ability to the environment. The resolution sensitivity of transmitting and receiving electromagnetic waves is low, and the anti-interference ability is poor. At the same time, with the development of wireless beam transmission technology, the anti-attack ability of related wireless receiving electromagnetic waves and the adaptability to complex electromagnetic environments are poor, and the transmission efficiency is reduced.

[0004] Due to the complexity of electronic equipment, once the natural environment of a wireless transmission node, such as air, lightning, thunderstorms, snowfall, terrain, geographical environment, etc., changes significantly, the electromagnetic environment of the wireless node will change accordingly, which will have a great impact on the sidelobe beam and mainlobe beam of the existing wireless beam transmission. It is necessary to reconfigure the relevant electromagnetic data to work normally, resulting in poor adaptability to the electromagnetic environment and anti-interference ability to complex environments. At the same time, traditional technical solutions usually increase the transmission power of the main lobe and use omnidirectional control beams to cover clutter and shield the influence of clutter in order to improve the anti-interference ability. The use of omnidirectional control beams will not only increase the overall transmission power, but also affect the receiving beam. In order to counteract the control of the transmission beam, the sensitivity and related power of the reception must also be improved. In addition, the use of control beams also further increases the electromagnetic radiation intensity of the wireless node to the external environment, causing other receiving devices to mistakenly receive the interfering wireless beam and invalidly identify it, resulting in the occurrence of string code / error code and other phenomena. On the other hand, since a single wireless receiving device such as radar / wireless detection cannot effectively detect, identify and prevent attacks in a timely manner when facing external interference / attack signals / energy beams, the effective beam cannot be transmitted in a timely and effective manner, thus affecting the normal implementation of the original business and causing transmission failures. Summary of the invention

[0005] Based on the problems raised by the above background technology, the purpose of the present invention is to provide a wireless beam transmission method and related equipment based on active controllable absorption / attenuation, which solves the problems that radar / wireless base station / wireless energy transmission equipment at this stage often has a large overall power, reduced wireless transmission efficiency, and anti-interference ability to the environment due to the special electromagnetic environment under the influence of the sidelobe clutter effect of wireless beam transmission. The resolution sensitivity of the transmitted and received electromagnetic waves is low and the anti-interference ability is poor. At the same time, with the development of wireless beam transmission technology, the anti-attack ability of the related wireless receiving electromagnetic waves and the poor adaptability to complex electromagnetic environments, and the problem of reduced transmission efficiency.

[0006] The present invention is achieved through the following technical solutions:

The beam detection module in the corresponding direction is used to receive and detect the environment detection beam, and then the detection result is fed back to the beam transmitting and receiving module. The beam transmitting and receiving module analyzes the control strategy according to the detection result and generates the control strategy under the corresponding direction.

[0043] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0044] Example 1

[0045] Figure 1 A schematic diagram of a flow chart of a wireless beam transmission method based on active controllable absorption / attenuation provided in Embodiment 1 of the present invention, such as Figure 1 As shown, the active controllable absorption / attenuation technology is physically modularized into a wireless beam transmission device, which includes a beam transmitting and receiving module, a beam detection module and a controllable wave absorbing module;

[0046] The wireless beam transmission device is used to implement a wireless beam transmission method, and the wireless beam transmission method includes the following steps:

[0047] The beam transmitting and receiving module transmits an environment detection beam to a corresponding direction, and when the beam detection module at the corresponding direction receives the environment detection beam, it collects information of the environment detection beam and feeds it back to the beam transmitting and receiving module;

[0048] The beam transmitting and receiving module performs control strategy analysis on the collected information to generate a control strategy. The beam transmitting and receiving module controls the controllable absorbing module to absorb / attenuate the non-working main lobe according to the control strategy.

[0049] It should be noted that due to the complexity of electronic equipment, once the natural environment of a wireless transmission node, such as air, lightning, thunderstorms, snowfall, terrain, geographical environment, etc., changes significantly, the electromagnetic environment of the beam transmitting and receiving module will change accordingly, which will have a significant impact on the sidelobe beam and mainlobe beam of the existing wireless beam transmission. It is necessary to reconfigure the relevant electromagnetic data to work normally, resulting in poor adaptability to the electromagnetic environment and poor anti-interference ability in complex environments. At present, electronic software and hardware are usually used to deal with the above shortcomings. However, the electronic software and hardware processing flexibility is small and the coding is complex, making it difficult to achieve absorption and attenuation of wireless beam transmission.

[0050] In view of the problems existing in the above-mentioned prior art, this embodiment provides a wireless beam transmission method based on active controllable absorption / attenuation. In this method, the active controllable absorption / attenuation technology is physically modularized into a wireless beam transmission device to reduce the environmental electromagnetic external interference caused by the beam during transmission and reduce the overall transmission power. Through physical modularization, the anti-interference ability to the electromagnetic environment, the anti-attack ability to external electromagnetic attacks, and the efficiency of the working beam are further improved. At the same time, the heat energy caused by the attenuation of the wave can be used to detect the energy density during transmission. Specifically, the process and effect of implementing the wireless beam transmission method using a physically modular wireless beam transmission device are as follows:

[0051] First, the beam transmitting and receiving module in the wireless beam transmission device is used to transmit the environment detection beam to the corresponding direction. The wireless transmitting and receiving module uses controllable directional attenuation technology to improve the module's anti-interference ability, effective power and resolution sensitivity, and dynamically uses the detection node to detect the electromagnetic working beam in different electromagnetic environments and the electromagnetic noise in the environment, so as to improve the sensitivity of receiving and identifying the beam and the dynamic adaptability of the equipment to the environment. The beam detection module corresponding to the beam transmitting and receiving module is used to receive the environment detection beam and detect it, and then the detection result is fed back to the beam transmitting and receiving module. The beam transmitting and receiving module analyzes the control strategy according to the detection result and generates the control strategy under the corresponding direction. The controllable wave absorbing module absorbs / attenuates the electromagnetic field under the corresponding direction according to the control strategy, and absorbs / attenuates in a directional manner to prevent normal / malicious interference from other non-working beams, thereby improving the equipment's anti-attack / interference ability. The beam transmitting and receiving module, the beam detection module and the controllable wave absorbing module all use modularization and master-slave backup technology to reduce the equipment failure rate.

[0052] Comparison between the conventional wireless transmission suppression method and the present invention Figure 2 As shown, the present invention can directionally suppress the circumferential side lobes while maintaining normal operation in the direction of the working main lobe, without using a control beam to reduce the ambient signal beam noise 0 point required by the working beam, reducing the transmission power, using active noise reduction technology, dynamically attenuating according to the actual environment, shielding and absorbing signals in a specific direction, and improving the device's ability to resist attack and false reception.

[0053] Furthermore, the controllable absorbing unit can use primary direct control / secondary control to control semiconductors and other materials to generate specific fields including but not limited to combinations of plasma fields, electromagnetic fields and force fields, and its attenuation band and attenuation power are controllable, and the receiving and sending directions are controllable.

[0054] Furthermore, the controllable wave-absorbing module is deployed on the wireless transmitting and receiving module. First, a metamaterial matrix is ​​used on the microscopic surface of the relevant wireless transmitting and receiving module, and the wave-absorbing characteristics at the microscopic level are directly controlled by controlling the relevant electronic components. The wave-absorbing characteristics of the material can also be indirectly affected by heat generated by current / voltage-induced electron transitions, so as to achieve controllable beam absorption / attenuation. Secondly, isoelectrically controlled plasma can be used to directly control the voltage to excite the semiconductor coating to produce plasma, and the semiconductor can be selectively excited to produce a plasma layer of corresponding intensity according to the signal intensity of the non-working electromagnetic wave to achieve absorption / attenuation of the specified beam.

[0055] The controllable absorbing unit, the wireless transmitting and receiving unit and the beam detection unit are all combined in a modular manner, and a single module failure can support hot replacement of a single module.

[0056] In an optional embodiment, when the beam detection module in the corresponding direction receives the environment detection beam, collecting information of the environment detection beam and feeding it back to the beam transmitting and receiving module includes the following steps:

[0057] The beam detection module receives an electromagnetic signal in a corresponding direction, and analyzes the electromagnetic signal to obtain electromagnetic signal parameters;

[0058] Constructing a distribution diagram of the electromagnetic signal in space according to the electromagnetic signal parameters, and dividing the distribution diagram into a working main lobe and a non-working main lobe;

[0059] The electromagnetic signal parameters of the non-working main lobe are transmitted to the beam transmitting and receiving module for control strategy analysis.

[0060] It should be noted that if Figure 3 As shown, before transmitting the working beam, the wireless beam transmitting and receiving module transmits the environmental detection beam in the corresponding direction according to the normal transmission power, and each detection unit in the beam detection module responds in each corresponding direction according to the transmitted detection beam, and each detection unit extracts the electromagnetic signal in the detection beam, and obtains the parameters of the electromagnetic signal, and draws a distribution diagram of the electromagnetic signal in space according to the electromagnetic signal parameters. Since the purpose of the present invention is to suppress the circumferential side lobes, that is, the non-working main lobes, the signals of the non-working main lobes in the distribution diagram are transmitted to the beam transmitting and receiving module in the embodiment of the present invention for control strategy analysis.

[0061] In an optional embodiment, transmitting the electromagnetic signal parameters of the non-working main lobe to the beam transmitting and receiving module for control strategy analysis includes the following steps:

[0062] The beam transmitting and receiving module summarizes the electromagnetic signal parameters of the non-working main lobe in all directions;

[0063] The electromagnetic wave spatial attenuation formula is used to calculate the electromagnetic signal parameters of the aggregated non-working main lobe, and a control strategy is generated based on the calculation results.

[0064] It should be noted that the beam transmitting and receiving module collects the frequency, amplitude, and phase information of the non-working main lobe direction of the detection electromagnetic beam by the beam detection unit, and transmits the detection beam amplitude and phase information in each direction to the control strategy calculation unit. The beam transmitting and receiving module collects the frequency, amplitude, and phase information of the non-working main lobe direction of the detection electromagnetic beam by the beam detection unit, and transmits the detection beam amplitude and phase information in each direction to the control strategy calculation unit. The control strategy calculation unit calculates the amplitude and phase information of the detection beam transmitting and receiving position according to the electromagnetic wave spatial attenuation formula based on the frequency, amplitude and phase information, and controls the beam transmitting and receiving module to absorb and attenuate the amplitude of the non-working beam in this direction according to the frequency, degree and phase information.

[0065] Specifically, during the working beam transmission process, each beam detection unit periodically detects the working electromagnetic field conditions and dynamically feeds back to the wireless beam transmitting and receiving unit. The wireless beam transmitting and receiving module forms relevant response strategies based on the data of each detection unit, and adjusts the transmission power and controllable absorbing unit according to the strategy to achieve sidelobe beam absorption / attenuation generated by the transmitting beam.

[0066] In an optional embodiment, the electromagnetic signal parameters of the non-working main lobe include: directional frequency, amplitude and phase information of the non-working main lobe.

[0067] In an optional embodiment, the wireless beam transmission device controls the controllable absorbing module to absorb / attenuate the non-working main lobe according to the control strategy, including:

[0068] The wireless beam transmission device adjusts the amplitude of the non-working main lobe in a specific direction according to the control strategy and generates control data;

[0069] The controllable wave absorbing module absorbs / attenuates non-working electromagnetic waves in a specific direction according to the control data.

[0070] It should be noted that the controllable wave absorbing module is Figure 4 As shown, the controllable absorbing module includes a main absorbing control unit and a slave absorbing control unit. The main absorbing control unit and the absorbing control unit are connected to the absorbing array through a node data power bus. The controllable absorbing module can realize absorption / attenuation of the non-working main lobe.

[0071] In this embodiment, the regional topographic map, temperature, electromagnetic working conditions, rain and snow intensity and other environmental parameters within the working range are periodically obtained through manual / network / sensor / etc. methods to establish an ideal electromagnetic wave direction map centered on the wireless beam transmitting and receiving module. Dynamic detection and identification of electromagnetic environments in different environments at different times are achieved, and the electromagnetic anti-interference ability and electromagnetic environment adaptability of related wireless devices are enhanced.

[0072] The orientation of the line beam during transmission is within a certain range. Electromagnetic induction of specific materials such as iron oxide and graphene can be used to generate a specific magnetic field. By generating a larger magnetic field, the electrons that the beam depends on are offset to the position of the absorbing / attenuating material in a specific area, causing power attenuation in a specific orientation.

[0073] In an optional embodiment, when the beam detection module does not receive the environment detection beam, the maximum value of the historical parameter is used as information feedback to the beam transmitting and receiving module.

[0074] It should be noted that when the detection unit in a beam detection module fails / is damaged, it cannot receive the environmental detection beam. The wireless beam transmission transmitting and receiving module can use the maximum value of the historical parameters as the default to replace the electromagnetic, signal attenuation and other carrier data of the current environment of this node if no valid parameters are obtained.
