Description

Technical Field

[0001] The present invention relates to the field of laser detection technology, and in particular to a laser information field detection system and method. Background Art

[0002] Laser beam-riding guidance is a remote control guidance method with humans in the loop and semi-automatic tracking. In this guidance method, when the aircraft is launched, the laser launch device emits a laser beam to illuminate the target, and the center line of the laser beam coincides with the aiming line. The aircraft enters the laser beam immediately after launch and always keeps flying in the laser beam until it hits the target. In order to achieve the guidance of the aircraft, the laser beam must be spatially frequency encoded to form a laser information field. During the flight of the aircraft, the laser receiving component at the tail of the aircraft continuously receives and decodes the laser information, calculates the direction and size of the aircraft's deviation from the center line of the laser beam, and then forms a control instruction to control the aircraft to always fly along the center line of the laser beam. In order to ensure that the laser irradiance received by the aircraft meets the requirements, the laser launch device continuously zooms the laser information field through the zoom system, so that the laser information field spot diameter at the position of the aircraft at each moment during the entire flight process is basically a certain value.

[0003] Whether the laser information field can work properly is directly related to the hit effect of the aircraft. Therefore, how to effectively detect the working parameters of the laser information field such as two-axis deviation, irradiance, zoom curve and coding information has become an important issue in the guidance and launch of aircraft.

[0004] In the current technical solution, the in-situ detection method before launch is mainly used. That is, before the aircraft is launched, the detection instrument is placed on the launch platform, and the laser emitted by the laser launch device enters the detection instrument at a close distance, thereby obtaining the working parameters of the laser information field.

[0005] The in-situ detection method is only applicable to the parameter detection of the laser information field at a close distance before the aircraft is launched. It has two main deficiencies: first, the detection conditions do not match the actual launch environment of the aircraft, and ignores the impact of interference such as impact and vibration during the aircraft launch on the laser information field; second, it can only be detected at a fixed position at a close distance, and it is impossible to directly obtain the laser information field parameters of the aircraft at different flight distances. Summary of the invention

[0034] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0036] In the following, reference will be made to Figures 1 to 10 , the various components of the laser information field detection system according to the embodiment of the present invention are described in detail. The laser information field detection system includes: a laser receiving component, a signal conditioning box, a wireless data receiving component and a data processing terminal.

[0037] The laser receiving component is located in the laser information field between the laser emitting device and the target, and is used to receive the optical signal, convert the optical signal into a command voltage signal and an energy voltage signal, and transmit it to the analog-to-digital conversion module. The laser receiving component includes a laser receiver, a coordinate solving circuit, and an energy solving circuit. Specifically, the laser receiver is used to receive the optical signal and convert the optical signal into a voltage signal; the coordinate solving circuit is used to convert the voltage signal into the command voltage signals Uy and Uz; and the energy solving circuit is used to convert the voltage signal into the energy voltage signal Ue.

[0038] The laser receiver includes an optical lens, an infrared filter, a photodiode and an amplifying and filtering circuit, wherein the optical lens is used to converge laser information onto the surface of the infrared filter; the infrared filter is used to perform optical filtering on the converged laser information and then send it to the photosensitive surface of the photodiode; the photodiode is used to convert the filtered laser information into level pulse information; and the amplifying and filtering circuit is used to perform amplifying and filtering on the level pulse information to convert the weak laser information into an easily recognizable voltage waveform.

[0039] The energy solution circuit includes a voltage follower circuit, an absolute value circuit, and an effective value circuit. The voltage follower circuit is used to receive a voltage signal and isolate the received voltage signal from the output voltage signal; the absolute value circuit is used to obtain an absolute value voltage signal of the output voltage signal of the voltage follower circuit; and the effective value circuit is used to obtain the effective value of the absolute value voltage signal to obtain the energy voltage signal Ue.

[0040] The signal conditioning box is used to install the laser receiving component and the signal conditioning box together, and is set up at a certain distance from the laser emitting device through a bracket to convert the command voltage signal and the energy voltage signal into digital signals. The signal conditioning box includes an analog-to-digital conversion module and a wireless data transmission module. The analog-to-digital conversion module is used to convert the command voltage signals Uy and Uz and the energy voltage signal Ue into digital signals, and send the digital signals to the wireless data transmission module in a serial port manner; and the wireless data transmission module is used to encrypt the digital signals and transmit the encrypted digital signals in a mesh manner.

[0041] The wireless data receiving component is used to receive the encrypted digital signal and transmit it to the data processing terminal. The wireless data receiving component includes a wireless data receiving module and a power display module, wherein the wireless data receiving module is used to receive the encrypted digital signal from the wireless data transmission module through the data receiving antenna, and transmit the encrypted digital signal to the data processing terminal via the cable; the power display module is used to increase the human-computer interactivity. When the power is sufficient, all three full-color LED lamp beads are lit; when the power drops to 50%, the blue lamp bead goes out, and the red and green lamp beads are lit; when the power drops to 25%, the blue and green lamp beads go out, and only the red lamp bead is lit; when the power is too low, all three color lamp beads go out.

[0042] The data processing terminal is used to obtain laser information field parameters based on digital signals, wherein the laser information field parameters include: two-axis deviation between the center line of the laser information field and the aiming line, laser information field zoom, laser irradiance and laser frequency coding. The data processing terminal is used to calculate the two-axis deviation between the center line of the laser information field and the aiming line according to the command voltage signals Uy and Uz. The irradiance is determined according to the energy voltage signal Ue; the laser information field zoom curve is determined according to the laser information coding measured by the laser receiver at different times. The actual zoom curve is determined according to the laser information coding measured by the laser receiver at different times. Specifically, the laser information field zoom changes the laser beam divergence according to a certain rule, so the laser spot diameter corresponding to a certain fixed position will also change according to a certain rule. The laser information coding corresponding to different positions in the spot is different. The distance between the laser receiver placed at this fixed position and the laser center axis is unchanged, so the actual zoom curve can be inferred from the laser information coding measured by the laser receiver at different times. The irradiance corresponds to the laser energy size, which is reflected by Ue. Laser frequency coding is implemented in the laser emitting device, which is equivalent to different codes corresponding to different positions of the laser circular cross section, which are then received by the laser receiver and resolved into Uy and Uz, corresponding to the two-dimensional coordinate position. For example, the restoration is performed based on the corresponding relationship between the measured value and the actual value.

[0043] The laser receiving assembly is arranged at any position between the laser emitting device and the target and the laser receiving assembly is kept in the laser information field. According to the position where the laser receiving assembly is arranged between the laser emitting device and the target, the laser information field parameters at different distances of the aircraft can be detected in the actual environment of the aircraft launch.

[0044] Another specific embodiment of the present invention discloses a laser information field detection method, including: installing a laser receiving component and a signal conditioning box together, erecting them at a certain distance from a laser emitting device through a bracket and setting them in a laser information field between the laser emitting device and a target; receiving an optical signal through the laser receiving component, converting the optical signal into a command voltage signal and an energy voltage signal and transmitting them to an analog-to-digital conversion module; converting the command voltage signal and the energy voltage signal into a digital signal through the signal conditioning box, and providing them to a data processing terminal via a wireless data transmission / reception module; and obtaining laser information field parameters based on the digital signal through the data processing terminal, wherein the laser information field parameters include: a two-axis deviation between a center line of the laser information field and a sighting line, a laser information field zoom curve, irradiance, and laser frequency coding.

[0045] Acquiring laser information field parameters based on digital signals through a data processing terminal includes: calculating the two-axis deviation between the center line and the aiming line of the laser information field according to the command voltage signals Uy and Uz; determining the irradiance according to the energy voltage signal Ue; and determining the laser information field zoom curve according to the laser information coding measured by the laser receiver at different times.

[0046] The optical signal is received by a laser receiver and converted into a voltage signal; the voltage signal is converted into a command voltage signal Uy and Uz by a coordinate solving circuit; and the voltage signal is converted into an energy voltage signal Ue by an energy solving circuit.

[0047] Hereinafter, the laser information field detection system according to the embodiment of the present invention is described in detail by way of a specific example.

[0048] 1. System composition. Reference Figure 1 The laser information field detection system is mainly composed of laser receiving components, signal conditioning box, wireless data receiving components, data processing terminal, data processing software, bracket and special accessories. The laser receiving component is mainly composed of laser receiver, coordinate solving circuit and energy solving circuit, and the signal conditioning box is composed of analog-to-digital conversion module, wireless data transmission module and power supply module.

[0049] 2. Working Principle. Reference Figure 2When the laser receiving component is in the laser information field, the laser receiver receives the optical signal and converts the optical signal into a voltage signal, which is sent to the coordinate solution circuit and the energy solution circuit. The coordinate solution circuit and the energy solution circuit condition the optical signal of the laser receiver into the instruction voltage signals Uy, Uz and the energy voltage signal Ue for easy processing, and send them to the analog-to-digital conversion module. The analog-to-digital conversion module converts the three voltage signals Uy, Uz, and Ue into digital signals, and then sends the digital signals to the wireless data transmission module in serial port mode. After receiving the digital signal, the wireless data transmission module encrypts the digital signal, transmits the data in mesh mode, and converts it into the network port protocol through the wireless data receiving module, and sends it to the data processing terminal through the network port. Finally, the data processing terminal realizes data collection, processing, analysis and result display.

[0050] refer to Figure 3 The laser receiving component is installed together with the signal conditioning box, and is set up at a certain distance from the laser emitting device through a bracket, so that it is located in the laser field information field emitted by the laser emitting device. After the laser receiving component receives the laser information field signal and is processed by the signal conditioning box, the detected information is encrypted and transmitted via the wireless data link through the data transmission antenna. The wireless data receiving component is connected to the data processing terminal through a cable and placed on the side of the laser emitting device. The wireless data receiving component receives the information sent by the signal conditioning box through the data receiving antenna and sends it to the data processing terminal.

[0051] Because the command voltage Uy and Uz are proportional to the command value, the two-axis deviation between the center line of the laser information field and the aiming line can be calculated based on the Uy and Uz test values. When the laser receiving component is in a position deviating from the center line, according to the laser information field zoom curve and the tested Uy and Uz voltage values, through the software calculation and analysis of the data processing terminal, it can be determined whether the laser information field zoom meets the requirements. During the detection process, the laser frequency code is emitted at a certain period and frequency, and the laser receiver solves the code information in real time and sends it to the data processing terminal.

[0052] 3. Workflow: 1. According to the requirements of zoom test or two-axis deviation test, the front personnel will set up the laser receiving component at a certain distance from the laser emitting device. At the same time, the rear personnel will connect the wireless data receiving component to the data processing terminal and place it on one side of the platform where the laser emitting device is located. 2. The front personnel and the rear personnel will turn on the equipment switch respectively, and the switch indicator light will light up. After the indicator lights of the data transmitting antenna and the data receiving antenna turn green, the wireless transmission is normal and the detection system can work. 3. The rear personnel will open the data processing software on the data processing terminal and confirm that it is running normally, then aim the laser emitting device at the laser receiving component and emit the laser. 4. After the emission is completed, the data processing software stops collecting, analyzes the data detection collection results, and determines whether the working status of the laser information field meets the requirements. 5. If the test results meet the requirements, the test is completed. If it does not meet the requirements, reset and adjust the laser emitting device and repeat steps 3-5.

[0053] 4. Design of main components.

[0054] 1. Laser receiving component: reference Figure 4 The main function of the laser receiving component is to convert the modulated light signal of the laser information field at a certain position into a voltage signal, and then send it to the data processing terminal through wireless data transmission. The laser receiving component consists of a laser receiver, a coordinate solving circuit, and an energy solving circuit. The function of the laser receiver is to receive the modulated light signal of the laser information field, and convert the light signals of different frequencies into electrical pulses of corresponding frequencies, and then transmit the pulse electrical signal to the coordinate solving circuit, which will continuously demodulate the Uy and Uz DC voltages reflecting the position of the laser receiver in the laser information field in real time.

[0055] The working principle of the laser receiver is as follows: the laser information is focused onto the surface of the infrared filter through an optical lens, and then sent to the photosensitive surface of the photodiode after optical filtering by the infrared filter. The photodiode converts the laser information into level pulse information. The connection board completes the connection between the photodiode and the amplification and filtering circuit. The level pulse output by the photodiode is sent to the preamplifier circuit of the amplification and filtering circuit for primary amplification, and then sent to the high-pass filter circuit to filter out the low-frequency components. After secondary amplification, it is sent to the low-pass circuit for tertiary amplification and filtering out the high-frequency components, thereby achieving the purpose of converting weak laser information into an easily recognizable voltage waveform and realizing the circuit frequency domain filtering.

[0056] The function of the coordinate solving circuit is to process the electrical pulse signal output by the laser receiver into two signals Uy and Uz that follow the change of the line deviation amplitude, representing the position of the laser receiver relative to the optical axis in the laser information field.

[0060] The wireless data transmission module adopts a plug-and-play MESH transmission board, point-to-point transmission mode, and an internationally certified encryption method. Its main function is to send TTL serial port signals to the data processing terminal wirelessly.

[0061] The power module is divided into a battery and a DC-DC power regulator module. The battery uses a domestically produced low-temperature 18650 lithium battery, with a single battery capacity of 2.5Ah, and a 4-series-2-parallel solution is used to achieve a capacity of 5Ah. The DC-DC power regulator module uses domestically produced TH20W24S-13V and TH20W24D-12V6 to power the equipment, isolate the power input and output, and improve the insulation resistance and dielectric strength of the internal signal and the shell, thereby improving the safety of the equipment.

[0062] 3. Wireless data receiving component: The wireless data receiving component is mainly composed of a wireless data receiving module, a power module, and a power display module. Its main function is to receive the data detected by the laser receiving component and then send it to the data processing terminal.

[0063] The wireless data receiving component and the wireless data transmission module in the signal conditioning box are combined into a communication system. The hardware circuits of the two are consistent, both have the function of sending and receiving, and are used together to complete data transmission and communication.

[0064] The power module is consistent with the power module in the signal conditioning box.

[0065] The power display module is used to increase human-computer interaction. The operator can grasp the equipment's battery life according to the power indication and plan the test content reasonably. The power display module solution uses F124 to control a full-color common cathode LED. When the power is sufficient, all three-color beads of the full-color LED light are lit; when the power drops to 50%, the blue bead goes out, and the red and green beads are lit; when the power drops to 25%, the blue and green beads go out, and only the red bead is lit; when the power is too low to support the system, the three-color beads are all extinguished.

[0066] 4. Data processing terminal: The data processing terminal uses a domestically produced high-performance notebook.

[0067] 5. Data processing software: Data processing software is the main means of human-computer interaction, used to process test data and analyze results. The main functions are: reference Figure 7 and Fig. 9 , (1) merge the laser information field detection information collected by the laser receiving component with the relevant setting information and save it as a test data file; refer to Figure 7 and Fig.10 , (2) Analyze and evaluate whether the two-axis deviation between the center line of the laser information field and the aiming line is qualified; (3) According to the laser information field parameter indicators, analyze and process the voltage data to determine whether the laser information field is working normally; (4) Reference Figure 7 , Figure 8 ,and Fig.11 , has test data management functions and can display, query, delete and other operations on test data records.
