Description
Technical Field
The invention belongs to the technical field of reconfigurable short-wave antennas, and relates to a high-power reconfigurable short-wave antenna based on optical energy-carrying control.
Background
The short wave can be transmitted by means of sky waves and ground waves, has the advantages of long communication distance, low cost and the like, and is widely applied to the military and civil fields. The short wave working frequency is 3MHz ~30MHz, and frequency range is wide, and the antenna size of different frequency channels differs great, and the antenna of fixed length can only solve the short wave communication of a certain frequency channel, can't realize the broadband transmission demand. The reconfigurable antenna changes the effective length of the antenna according to the use requirement, and the function of multi-band switching communication is realized.
In recent years, researchers have proposed various reconfigurable antenna technologies, in which the principle of frequency reconfiguration is to change the connection relationship and effective length of antenna elements through a switching device, thereby reconfiguring the resonant frequency of an antenna. The antenna element is usually divided into several units, which are connected by a controllable switching device; when the switch device is disconnected, the link of the antenna unit is disconnected, the length of the antenna oscillator is reduced, and the antenna is in a high-frequency state; when the switching device is conducted, the adjacent antenna units are connected, the length of the antenna oscillator is increased, and the antenna works in a lower frequency band.
However, short-wave antennas have the characteristics of low frequency, large mechanical size and high antenna transmission power (kW level) during operation, so that the short-wave antenna reconfiguration cannot adopt the reconfiguration scheme used by the known base station antennas, i.e. the antenna reconfiguration is realized by controlling the low-power transistors to be turned on or off. The high-power reconstruction short-wave antenna usually needs a mechanical switch mechanism to continuously work in a kW-level high-power emission state. Meanwhile, the switching mechanism also needs to be provided with a power supply and a control signal required by action by a remote control device so as to realize the on-off operation of the switching mechanism. Therefore, feeding and controlling a high-power mechanical switch are one of the difficulties in antenna reconstruction, and two technical approaches exist at present:
the first type is to control the switching mechanism by an electrical signal in a wired manner. The invention discloses an antenna device, a communication product and a reconstruction method of an antenna directional pattern, 201910866772.6 and 20210312, and a directional pattern reconfigurable antenna, a reconstruction method and a wireless terminal device, 201810179377.6 and 20180928, and the like. This approach requires a control cable of metallic media to be laid in the vicinity of the antenna. Due to the existence of the metal cable, a local conductor boundary is introduced into a free space near the antenna, so that on one hand, the electromagnetic field distribution around the antenna is damaged, and the problems of radiation pattern deterioration, resonant frequency deviation, abnormal reflection and the like are caused; on the other hand, when the antenna outputs high power, electromagnetic waves can generate strong induced currents in nearby metal wires, normal operation of the switching mechanism controller is affected in the form of conducted interference, and electromagnetic protection of the switching mechanism controller is quite difficult.
The second type is that the metal medium can be far away from the antenna element to a certain extent by controlling the switch mechanism in a non-contact energy transmission mode. For example, the invention patent is based on wireless energy-carrying communication of an active clamped forward inverter, 201810187649.7, 20180622. The technology can drive a mechanical switch in a mode of electromagnetic coupling wireless power supply in the reconfigurable antenna, thereby realizing the frequency reconfiguration of the antenna and avoiding the direct connection of a metal cable and a switch device. However, the short-wave antenna has a large size, and the common wireless power supply distance is difficult to directly cover the length of the antenna element, and the energy required for driving the high-power mechanical switch cannot be provided at a long distance.
In a word, the prior art cannot be applied to a high-power large-size reconfigurable short-wave antenna.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The reconfigurable short wave antenna has the characteristics of high power and long mechanical size of an antenna oscillator, the switch mechanism 3 is positioned between the short wave antenna units, and if a cable is adopted to transmit a control signal and a working power supply to the switch mechanism 3, the transmission cable and the short wave antenna can generate mutual interference to influence the performance of the antenna. The invention breaks through the traditional design framework, adopts the light energy carrying communication mode to drive and control the switch mechanism 3, and avoids the influence on the antenna performance. Because the power of optical signals transmitted through the optical cable is limited and is far less than the power transmitted by the cable, the components in the switch mechanism cannot be directly driven, the invention stores energy in the optical communication process through the micro energy storage equipment, and the energy is instantaneously released when the switch device is driven, thereby solving the problem that the switch mechanism cannot be directly driven by the optical cable transmission power. Meanwhile, when the light energy-carrying controller does not send a light source, the micro energy storage device can maintain the switching mechanism to work for a period of time (second level), and the condition that the switching mechanism is powered off when light signals (on/off) are transmitted is avoided. In the high-power short-wave antenna reconfiguration mechanism, light is used as energy and signals and is transmitted through a non-metal medium (optical cable), so that the antenna reconfiguration mechanism is driven and controlled.
The embodiment of the invention provides a high-power reconfigurable short-wave antenna based on optical energy-carrying control, which is shown in figures 1-2 and comprises:
the light energy carrying controller 1 is used for driving the light emitting diodes according to an external control instruction, generating light energy carrying signals by modulating the on-off time sequence of the light emitting diodes and sending the light energy carrying signals to each switch mechanism 3 through the optical cable 2; and a switch mechanism 3 is arranged between two adjacent antenna units 4, the switch mechanism 3 comprises a hollow tube 6 for installing the optical cable 2, and the optical cable 2 passes through the hollow tube 6. The visible light generated by the light emitting diode is transmitted to the first optical cavity 10 of each switch mechanism 3 through the optical cable 2, and the whole process is an optical energy transmission process; at the same time, information can be represented by continuously controlling the on and off of the leds, so that the light energy carrying controller 1 can generate a light energy carrying signal for simultaneously transmitting energy and information.
The structure of the light energy-carrying controller 1 is shown in fig. 3, and includes a controller circuit 8, a control instruction is input into the controller circuit 8 through an RS232 communication protocol, the controller circuit 8 is connected with a plurality of light emitting diode circuits through transistors, the light emitting diodes are installed in a first optical cavity 10, light of the light emitting diodes is converged in the first optical cavity 10 through an optical mirror 9, the converged light is emitted into the optical cable 2, a power supply module 7 supplies power to all the light emitting diodes, a current limiting resistor is connected between the power supply module 7 and each light emitting diode for adjusting current of the loop, rated currents of the light emitting diodes with different powers are different, the power supply module 7 outputs standard voltages (such as 5V and 12V), and the power supply module 7 is connected with an external working power supply.
The controller circuit 8 comprises an RS232 interface circuit, a processor circuit and a control instruction driving circuit; the RS232 interface circuit is used for level conversion, and a MAX3232 chip is adopted to convert an RS232 level signal of a control instruction into a UART level signal of a processor circuit, and the RS232 interface circuit is a known circuit; the processor circuit adopts a microprocessor as a core device, in the embodiment, the MSP430F149 is used as a processor, a UART interface of the processor is connected with the output end of the RS232 interface circuit, and P1.0-P1.2 interfaces of the processor are connected with transistors and used for controlling the conduction of the transistors.
In the embodiment, the transistor is an NPN type triode with the model of MJD127G, and the function of the transistor is to realize the conduction or the cut-off of the triode through a control instruction (high level/low level) output by the light emitting diode control circuits P1.0-P1.2. When the control instruction is high level, the triode is conducted, and the light emitting diode starts to emit light; when the control command is low level, the triode is cut off, and the light emitting diode stops emitting light. Because the light emitting diode outputs an optical signal carrying energy, the rated power is high, and therefore, a device capable of passing large current needs to be selected for the triode.
The switch mechanism 3 is used for receiving the light energy carrying signals and converting the light energy carrying signals into two paths of electric energy carrying signals through a photoelectric conversion circuit, and the time sequence of the electric energy carrying signals is the same as that of the light energy carrying signals; as shown in fig. 4, the photoelectric conversion circuit includes a silicon photocell set, the silicon photocell set is of the BPW34S type, the silicon photocell set is formed in a series connection manner, after being irradiated by a light beam, the silicon photocell set outputs a voltage of about 3.3V, and when the light beam disappears, the silicon photocell set outputs 0V. The output voltage of the silicon photovoltaic cell set is directly sent to the processor 16, the processor 16 adopts a microprocessor MSP430F149, and the output voltage of the silicon photovoltaic cell set is sent to an RXD pin of a UART interface of the medium microprocessor MSP430F 149. Because the well-known serial port level conversion chip is not needed for conversion, and the photoelectric conversion time of the silicon photocell is very short, namely, the silicon photocell is in the order of microseconds, the output voltage signal is synchronous with the optical signal, and the direct conduction communication between the optical signal and the processor is realized.
As shown in fig. 5, the light energy-carrying controller 1 generates a light energy-carrying signal, and transmits the light energy-carrying signal to the second optical cavity 20 through the optical cable 2, the optical cable 2 outputs a light beam 11 in the second optical cavity 20, the light beam 11 irradiates on a silicon photocell, the silicon photocell is mounted on the photoelectric conversion plate 12, the second optical cavity 20 is used for diffusing the light transmitted by the optical cable 2 to the photoelectric conversion plate 12, and the larger the area covered by the light, the higher the electric energy converted by the photoelectric conversion plate 12. The high level converted by the photoelectric conversion circuit is + 28V; one path of the electric signal generates working voltage through the first conditioning circuit 15, and the voltage signal is processed by the conditioning circuit to generate an electric signal which is input to the processor 16; the first conditioning circuit 15 is used for acquiring an electrical signal (high or low level in the signal) from the voltage converted by the photoelectric conversion plate. Specifically, after being processed by the first conditioning circuit 15, an electric signal of the UART timing sequence is generated, the high level is 3.3V, and the low level is 0V; the signal is input to a processor 16, the processor 16 outputs the control level of a switching device according to the control information in the signal, and the two antenna units 4 adjacent to the switching mechanism 3 are short-circuited or disconnected, so that the reconfigurable short-wave antenna 5 is realized.
The other circuit of energy carrying signals generate working voltage through a direct current converter 13 in the switch mechanism 3 and output the working voltage to an energy storage capacitor 14, and the direct current converter 13 is used for stabilizing the voltage and outputting the voltage to the energy storage capacitor 14 for energy storage; the energy stored in the energy storage capacitor 14 provides working voltage for the processor 16 through the second conditioning circuit 17, and provides working voltage for the third conditioning circuit 18, and the energy storage capacitor 14 adopts a solid capacitor, so that voltage output can still be maintained when the optical signal disappears; the second conditioning circuit 17 is used to convert the +28V voltage in the energy storage capacitor 14 into a 3.3V working voltage used by the processor 16, and the third conditioning circuit 18 is used to convert the control signal output by the processor 16 into a driving level (the common control level for this type of switching device is 5V, 12V or 28V). When the 'off' information appears in the optical energy carrying signal, the switch mechanism 3 can still maintain the normal working time of the switch. When the light energy-carrying controller 1 stops sending the light signal, the energy of the energy storage capacitor 14 is consumed quickly, the magnetic latching relay 19 can still keep the current on/off state, the light signal is controlled to be on or off according to the time sequence, and the communication coding is realized. The photoelectric conversion circuit can convert the on/off optical signal timing into electric signal timing, and the electric signal can be directly processed by communication interface (such as UART, I) of the processor2C, etc.) receiving and identifying.
The working energy of the switch mechanism 3 is all from the light source sent by the light energy-carrying controller 1, the switch mechanism 3 adopts a magnetic latching relay 19 as a switch device, the switch device switches the switch state according to the control level of the processor 16, when the switch device is in the on state, the adjacent antenna units 4 are connected, and when the switch device is in the off state, the adjacent antenna units 4 are disconnected. When the light energy-carrying controller 1 does not output a light energy-carrying signal, the switching device keeps the current state, the switching mechanism 3 is in the non-operating state, the energy stored in the energy storage capacitor 14 can be consumed rapidly, and the switching mechanism 3 is in the power-off state; in this state, the switch mechanism 3 does not generate radiation to affect the working performance of the antenna, and meanwhile, the electromagnetic radiation between the antenna units 4 cannot act on the switch mechanism 3, so that the performance index of the antenna is effectively ensured. The switch mechanism can be maintained to work normally (when the LED lamp is off) during optical signal transmission, the stored energy can be consumed rapidly under the condition of no optical signal, and the influence of the switch mechanism on the performance of the antenna is reduced to the maximum extent.
The first conditioning circuit 15 is a level conversion circuit that converts the level of the electrical signal output from the photoelectric conversion circuit into a UART that can be recognized by the processor. The embodiment adopts a low-power MSP430F149 processor, and the UART level is the coms level. The second conditioning circuit 17 is a voltage regulator circuit, and stabilizes the output voltage of the energy storage capacitor to the working voltage required by the processor. The MSP430F149 used in the examples had an operating voltage of 3.3V. The third conditioning circuit 18 is a level conversion circuit that converts the level of the processor output to a level that can drive the control terminal of the magnetic latching relay. The relay used in the embodiment needs a TTL level, so the function of the third conditioning circuit 18 is to convert the coms level output by the controller to a TTL level.
Because the electrical signal power of the optical signal conversion is low, the switching mechanism 3 cannot be directly driven to normally work, the direct current converter 13 can perform voltage stabilization on the converted electrical signal and output the stabilized electrical energy to the energy storage capacitor 14 for charging, the output voltage of the energy storage capacitor 14 gradually rises in the charging process, and when the output voltage reaches the lowest working voltage of the processor 16, the second conditioning circuit 17, the third conditioning circuit 18 and the magnetic latching relay 19, the processor 16, the second conditioning circuit 17, the third conditioning circuit 18 and the magnetic latching relay 19 start to work. In general, when the energy storage capacitor 14 is fully charged, the output voltage is greater than the lowest working voltage of the processor 16, the second conditioning circuit 17, the third conditioning circuit 18, and the magnetic latching relay 19. Therefore, when the light beam 11 exists, the energy storage capacitor 14 is in a state of being charged and discharged; when the light beam 11 disappears, the energy storage capacitor 14 is in a discharge state, and when the output voltage is less than the lowest working voltage of the processor 16, the second conditioning circuit 17, the third conditioning circuit 18 and the magnetic latching relay 19, the switching mechanism stops working. Therefore, when the light beam 11 disappears, the energy storage capacitor 14 discharges for a second, which can quickly consume the stored energy, stop the switch mechanism 3, and avoid the influence of the electromagnetic field generated by the switch mechanism 3 on the antenna performance. Energy required by work can be provided for each switch mechanism in the system by carrying energy through the optical signal, and the effect of synchronous transmission of the energy and the signal can be realized. When the system does not transmit the light energy carrying signal, the switch mechanism 3 can be powered down rapidly, and the current on/off state is kept, so that the interference to the antenna during power-on work is reduced.
The external light energy-carrying controller 1 only has one light source, signals sent by the light source can be received by all the switch mechanisms 3, the light energy-carrying controller 1 sends light energy-carrying signals to the switch mechanisms 3 through the optical cable 2, the light energy-carrying signals carry coded information, the coded information comprises address codes of the switch mechanisms 3 and control instructions of the switch mechanisms 3, the processor 16 in each switch mechanism 3 controls the on-off operation of the switch according to the address codes and the control instructions in the signals, the switch mechanisms 3 can check whether the address codes are consistent with the mechanisms or not after receiving the signals, if the address codes are consistent with the mechanisms, the control instructions are executed, and if the address codes are inconsistent with the control instructions, the switch mechanisms do not respond to the instructions carried by the light information, and the control function of one light source on the switch mechanisms 3 is achieved.
The processor 16 in the switching mechanism 3 is a low-power microprocessor of the MSP430 series, and the keeper switch is a magnetic latching relay 19 with a high rated current. When the antenna has a reconfiguration requirement, an external device (such as a control computer or an electric tilt device) sends a control instruction to the light energy-carrying controller 1; the light energy-carrying controller 1 controls the on and off of the LED lamp set (with high sending illumination intensity) according to the received instruction and the serial data time sequence of UART (Universal Asynchronous Receiver/transmitter), and the time sequence of signals is shown in FIG. 6; the light energy carrying signal sent by the light energy carrying controller 1 is transmitted to each switch mechanism 3 through the optical cable 2.
In some embodiments, the external device is a control computer, the control computer is connected to the optical energy-carrying controller 1, the control computer sends a command to the RS232 interface of the optical energy-carrying controller 1 according to the system requirements (for example, reconstructing an XXMHz antenna) (the control interface protocol is established according to the system requirements), and then the optical energy-carrying controller 1 controls the corresponding switch mechanism 3 according to the command.
In some embodiments, the external device is an electrical tilt device (device connected to an antenna) in an antenna system, and a computer capable of controlling the present invention is integrated in the electrical tilt device.
