Description

Technical Field

[0001] This invention relates to the field of high-power microwave technology, and in particular to a system and method for transmitting synchronization signals and control signals in a strong electromagnetic environment. Background Technology

[0002] High-power microwave technology is a novel technology formed by the integration of multiple technologies, and it has gradually moved from theory to practice with the upgrading of new equipment. High-power microwave technology helps in the study of the electromagnetic compatibility of devices and equipment, and in understanding radiation damage and destruction mechanisms. High-power narrow pulses have become a research hotspot, and sometimes multiple transmitters of different frequency bands need to work together, which increases the requirements for the timing of the equipment. Currently, the common method is to use synchronous differential signals input to different transmitter control subsystems, and under the strict timing logic control of the main controller, they operate according to certain logic. However, because high-power microwave technology often uses high-power narrow pulses, a strong electromagnetic environment can be formed in a short time. This not only interferes with the long-distance transmission of electrical synchronization signals in large-scale high-power microwave transmitting devices, but also causes errors in the control signals, resulting in chaotic control logic. This limits the peak power of the transmitted pulse and affects the scale of the transmitting device, making it impossible to coordinate the operation of transmitters of more frequency bands. Summary of the Invention

The transmitter control system for different frequency bands is used to work together under the control and drive of the synchronization pulse signal and the clock signal. After generating and amplifying the microwave signal according to the second control signal, it is radiated to the designated space through the antenna.

The multimode high-speed parallel electro-optic conversion module is connected to the FPGA chip and is used to perform electro-optic conversion on the frame synchronization pulse and the waveform trigger pulse to output the corresponding high-speed optical coded pulse. The multimode low-speed parallel optical module is connected to the FPGA chip and is used to perform electro-optic conversion on the transmission synchronization pulse to output the corresponding low-speed optical analog pulse.

[0008] Furthermore, the delay time of the waveform trigger pulse and the transmit synchronization pulse is adjustable compared to the frame synchronization pulse, and the pulse width of the transmit synchronization pulse is adjustable.

[0009] Furthermore, the optical transceiver includes an optical transceiver main unit and optical transceivers in different wavelength bands; the optical transceiver main unit is used to convert the second control signal and the clock signal into optical signals respectively, and transmit them to the optical transceivers in different wavelength bands using wavelength division multiplexing technology; the optical transceivers in different wavelength bands are used to demultiplex the wavelength division multiplexing, demodulate the second control signal and the clock signal, and send them to the corresponding transmitter control system.

[0010] Furthermore, the optical terminal switchboard is located in the control room, while the optical terminal sub-units are located in the transmission room and close to the corresponding transmitter control system.

[0011] Furthermore, the transmitter control system for different frequency bands includes a frequency source, a control and protection device, and a transmitter; the frequency source is used to generate microwave signals according to a second control signal under the drive of a synchronization pulse signal and a clock signal; the control and protection device is used to control the transmitter to amplify and output the microwave signals under the drive of the synchronization pulse signal.

[0013] Furthermore, the control and protection device is equipped with an optical analog pulse demodulation board, which is used to convert the transmitted synchronization pulse in the synchronization pulse signal into an electrical synchronization signal.

[0014] Secondly, this application provides a method for transmitting synchronization signals and control signals in a strong electromagnetic environment, based on the transmission system for synchronization signals and control signals in a strong electromagnetic environment proposed above. The method includes: After receiving the user's operation command, the main controller sends the first control signal to the optical synchronizer and sends the second control signal to the transmitter control system of different bands through the optical transceiver.

No restrictions are imposed here.

[0021] Figure 1 This is a block diagram illustrating a high-power microwave transmitting device's transmission system for synchronization and control signals in a strong electromagnetic environment, as an exemplary embodiment of this application. Figure 1 As shown, in an exemplary embodiment, the transmission system for synchronization signals and control signals in this strong electromagnetic environment may include a master controller, an optical synchronizer, an optical transceiver, and transmitter control systems for different frequency bands. For ease of explanation, three frequency bands are used as an example, and the details are described below: After receiving the user's operation command, the master controller sends a first control signal to the optical synchronizer and a second control signal to the transmitter control systems of different bands via an optical transceiver. The optical synchronizer generates the synchronization pulse signal and clock signal required by the transmitter control systems of different bands based on the first control signal. The synchronization pulse signal is transmitted to the corresponding transmitter control system via an optical fiber assembly, and the clock signal is transmitted to the corresponding transmitter control system via an optical transceiver. The transmitter control systems of different bands work collaboratively under the control and drive of the synchronization pulse signal and clock signal, generating and amplifying microwave signals according to the second control signal, and then radiating them to the designated space through antennas.

[0022] In this embodiment of the invention, the optical synchronizer generates synchronization pulse signals and clock signals required for the operation of all subsystems based on the first control signal sent by the master controller. The synchronization pulse signals sent to each subsystem are transmitted to each transmission compartment via optical fiber components. The clock signal and the second control signal sent by the master controller are transmitted to each subsystem via wavelength division multiplexing (WDM) technology through an optical transceiver for coordinated operation. This embodiment of the invention transmits synchronization and control signals through an optical path composed of an optical synchronizer and an optical transceiver, avoiding interference from strong electromagnetic environments and ensuring the coordinated and orderly operation of each subsystem. This method does not require the master controller to strictly adhere to the timing sequence, reducing the requirements for the control system. Furthermore, the use of optical coding technology strictly controls the jitter of the synchronization signal, ensuring the accuracy of the timing sequence.

[0023] Figure 2 This is a schematic diagram illustrating the working principle of an optical synchronizer as shown in an exemplary embodiment of this application. Figure 2 As shown, the optical synchronizer includes a communication module, a clock generation module, and an optical pulse generation module. The communication module receives the first control signal sent by the master controller and reports monitoring information to the master controller. The clock generation module generates a clock signal at a preset frequency and sends the clock signal to the transmitter control systems of different bands via an optical transceiver. The optical pulse generation module is connected to the communication module and the clock generation module, and performs pulse modulation based on the first control signal and the clock signal to generate the synchronization pulse signals required for different bands. The number of optical path groups generated by the optical synchronizer is consistent with the number of optical transceivers and the number of transmitter control systems, so that each group of optical synchronization pulse signals controls the transmitter control system of the corresponding band.

[0024] Specifically, the communication module receives gigabit network control commands (i.e., the first control signal) from the main controller via a microcontroller unit (MCU) chip, converts them into serial data, and sends them to the FPGA chip of the optical pulse generation module. The clock generation module generates a preset frequency clock signal of 100MHz. The 100MHz clock signal output by the clock generation module serves two purposes: firstly, as a reference clock for the internal FPGA chip; and secondly, after electro-optical conversion, long-distance transmission, and photoelectric conversion by the optical transceiver, it is used as a reference clock for the optical pulse demodulation module installed in the transmitter control system to recover the electrical pulse signal. Driven by the 100MHz clock, the optical pulse generation module can use the FPGA chip to perform pulse modulation according to the control word, generating multiple sets of synchronization pulse signals required by the transmitter control system for each band. Each set of synchronization pulse signals includes a frame synchronization pulse, a waveform trigger pulse, and a transmission synchronization pulse.

[0025] The optical pulse generation module can be divided into high-speed and low-speed channels based on the requirements for the synchronization signal pulse width and inter-pulse jitter. For frame synchronization pulses and waveform trigger pulses with higher requirements, the encoded control data is converted into optical encoded pulses through a high-speed serial transceiver interface with a built-in clock data recovery circuit. Then, high-speed optical encoded pulses are output through a small form-factor pluggable (SFP) electro-optical conversion module. In an optional implementation of this embodiment, the high-speed serial transceiver interface can be a commercially available specific model, such as the Xilinx GTX series high-speed transceiver. It is understood that any other high-speed serial transceiver module that can achieve the same or higher data rate and protocol functions can be used in this invention. For transmission synchronization pulses with less stringent requirements, low-speed analog optical pulses can be generated using low-speed analog light intensity modulation. Specifically, the FPGA chip is connected to a multimode high-speed parallel electro-optical conversion module via a high-speed serial transceiver interface for outputting high-speed optical encoded pulses; the FPGA chip is also connected to a multimode low-speed parallel optical module for outputting low-speed optical analog pulses. Both the multimode high-speed parallel electro-optical conversion module and the low-speed parallel optical module are connected to a connector interface.

[0026] At the receiving end of the synchronization pulse signal, the optical coded pulse demodulation board (located within the frequency source of the transmitter control system) and the optical analog pulse demodulation board (located within the control and protection device of the transmitter control system) convert the optical signal into a compliant RS422 differential level. The optical coded pulse demodulation board uses a high-speed serial transceiver interface to receive data from the frame synchronization pulse optical signal and the waveform trigger pulse optical signal. The reference clock of the high-speed serial transceiver interface and the 100MHz clock of the optical synchronizer are from the same source. After serial-parallel forwarding, the received data is decoded and output as a differential level.

[0027] Figure 3 This is a timing diagram of the synchronization pulse signal generated by the optical synchronizer provided in an embodiment of the present invention. Figure 3 As shown, after the master controller sends a control command to the optical synchronizer, the optical synchronizer receives the control command through the communication module and converts it into a corresponding control word. The control word of the optical synchronizer contains the settings of four delay parameters: delay a, delay b, delay c, and delay f. Delay a is defined as the delay time between the rising edge of the current band waveform trigger pulse and the rising edge of the current band frame synchronization pulse; delay b is defined as the delay time between the rising edge of the current band transmit synchronization pulse and the rising edge of the current band frame synchronization pulse; delay c is defined as the pulse width of the current band transmit synchronization pulse; and delay f is defined as the delay time between the rising edge of the current band frame synchronization pulse and the rising edge of the first band frame synchronization pulse.

[0028] After demodulation by the transmitter control system, the frame synchronization pulse and waveform trigger pulse are converted into strictly timed electrical signals. The rising edge of the frame synchronization pulse is used to drive the control command of the second control signal sent by the frequency source activation master, and the rising edge of the waveform trigger pulse drives the output of the microwave signal. The delay time between the two signals can be set according to the actual activation time of the frequency source through delay parameters. The transmit synchronization pulse is sent to the control and protection device to drive the insulated gate bipolar transistor (IGBT) device to turn on, thereby opening the microwave amplification channel. The delay time and width of the transmit synchronization pulse can be set through delay parameters. The setting of delay parameters can not only be used to compensate for the delay time error caused by the small difference in the optical path transmission path to maintain synchronization, but also to change the delay parameters according to the actual working needs of the transmitter control system to obtain better transmission timing, thereby improving the applicability and stability of the system.

[0029] Optionally, in an exemplary embodiment, the optical transceiver includes a main optical transceiver and optical transceivers of different wavelength bands. In this embodiment, the optical transceiver includes one main optical transceiver and three optical transceivers. The main optical transceiver is located in the control room and is used to convert the second control signal and the clock signal into optical signals, respectively, and transmit them to the optical transceivers of different wavelength bands using wavelength division multiplexing (WDM) technology. The optical transceivers of different wavelength bands are located in the transmission room and close to the corresponding transmitter control system, and are used to demultiplex the WDM, demodulate the second control signal and the clock signal, and send them to the corresponding transmitter control system.

[0030] In this embodiment of the invention, the optical transceiver converts the second control signal sent by the master controller into an optical signal for transmission. Wavelength division multiplexing (WDM) technology is used for transmission to simplify the optical cable as much as possible. The lengths of the three sets of optical cables from the optical transceiver to the optical transceiver remain unchanged regardless of the placement. This device has high requirements for latency. To reduce the error caused by transmission distance, the optical fibers used to connect the output port of the optical synchronizer and the optical synchronization signal receiving port of the transmitter control system are kept to the same length and type. Methods employed include, but are not limited to, connecting optical fiber extension lines of equal length to minimize the impact of the transmission path on latency. The optical transceiver is used to demultiplex the WDM-multiplexed optical signal and transmit it to the corresponding transmitter control system via optical fiber.

[0031] Optionally, in an exemplary embodiment, the transmitter control system for different frequency bands includes a frequency source, a control and protection device, and a transmitter. The frequency source generates a microwave signal according to a second control signal, driven by a synchronization pulse signal and a clock signal; the frequency source is equipped with an optical coded pulse demodulation board for converting the frame synchronization pulse and waveform trigger pulse in the synchronization pulse signal into an electrical synchronization signal according to the clock signal. The control and protection device controls the transmitter to amplify and output the microwave signal under the drive of the synchronization pulse signal. The control and protection device is equipped with an optical analog pulse demodulation board for converting the transmit synchronization pulse in the synchronization pulse signal into an electrical synchronization signal.

[0032] Figure 4 This is a schematic diagram illustrating the working principle of the optical coded pulse demodulation board provided in an embodiment of the present invention. Figure 4 As shown, the optical encoded pulse demodulation board includes a multimode high-speed photoelectric conversion module, an FPGA processing circuit, and an output pulse interface circuit. The multimode high-speed photoelectric conversion module converts the received frame synchronization pulse and waveform trigger pulse multimode optical signals into corresponding high-speed differential signals. The FPGA processing circuit, based on a 100MHz reference clock signal, restores the high-speed differential signals of the frame synchronization pulse and waveform trigger pulse to low-voltage transistor-transistor logic (LVTTL) electrical pulse signals through its internal high-speed serial transceiver interface. The output pulse interface circuit converts these signals into RS422 differential level outputs. The 100MHz clock for optical encoded pulse demodulation and the optical synchronizer are from the same source as the 100MHz clock for optical encoded pulse modulation, which effectively avoids inter-pulse jitter and ensures the quality of the synchronization signal.

[0033] In this embodiment of the invention, after receiving the second control signal, the frequency source parses the corresponding control word, and the internally installed optical coded pulse demodulation board generates a frame synchronization signal and a waveform trigger signal. The frame synchronization signal drives the frequency source to respond to the control word, and under the trigger of the waveform trigger signal, it generates an excitation signal with the corresponding pulse width and frequency point, which is input to the transmitter. Provided the protection logic is correct, upon receiving the transmission synchronization signal, the control protection device controls the transmitter to amplify the excitation signal and radiate it through the antenna.

[0034] In this embodiment of the invention, an optical synchronization pulse signal is generated by an optical synchronizer, and a control signal is transmitted through an optical transceiver using wavelength division multiplexing technology. The signal is then transmitted to the transmitter control system via optical fiber, minimizing the use of electrical signals in the transmission path. The use of optical transmission avoids interference from strong electromagnetic environments on the transmitted signal.

[0035] When the optical synchronizer generates the optical synchronization pulse signal, it uses a high-speed serial transceiver interface for pulse encoding, and then outputs the optically encoded pulse through the SFP electro-optical conversion module. At the receiving end, corresponding optically encoded pulse demodulation technology is employed. The pulse demodulation uses a 100MHz clock, and the optical synchronizer combines the optically encoded pulse with the 100MHz clock, ensuring that the synchronization signal is not interfered with by strong electromagnetic interference and significantly reducing inter-pulse jitter, thus guaranteeing the quality of the synchronization signal.

[0036] In terms of optical path transmission, this invention ensures the consistency of the transmission path as much as possible by adding extension lines. At the same time, by controlling the delay parameter, it can not only offset the delay time error introduced by the small difference in the optical path transmission path to maintain synchronization, but also change the delay parameter according to the actual working needs of the transmitter control system to obtain a better transmission timing, thereby improving the applicability and stability of the system.

[0037] This invention also provides a method for transmitting synchronization signals and control signals in a strong electromagnetic environment, based on the system for transmitting synchronization signals and control signals in a strong electromagnetic environment provided in any of the above embodiments. The method includes: after receiving an operation command from a user, the main controller sends a first control signal to an optical synchronizer and sends a second control signal to the transmitter control system of different bands through an optical transceiver; the optical synchronizer generates synchronization pulse signals and clock signals required by the transmitter control system of different bands according to the first control signal; the synchronization pulse signals are transmitted to the transmitter control system of the corresponding band through an optical fiber component, and the clock signals are transmitted to the transmitter control system of the corresponding band through an optical transceiver; the transmitter control systems of different bands work together under the control and drive of the synchronization pulse signals and clock signals, and generate and amplify microwave signals according to the second control signal and radiate them to a designated space through an antenna.
