Detailed Description
To make the purpose, technical solutions and advantages of the embodiments of the present specification clearer and more complete, the technical solutions in the embodiments of the present specification will be described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are part of the embodiments of the present specification, rather than all of the embodiments, and all other embodiments obtained by a person having ordinary skill in the art without making creative efforts based on the embodiments in the present specification belong to the protection scope of the present specification.
The scheme provided by the specification is described below with reference to the accompanying drawings.
Fig. 1 shows a flow chart of a method for multi-dimensional signal based object localization according to an embodiment. It is to be understood that the method may be performed by any device, apparatus, platform having computing, processing capabilities. As shown in fig. 1, the method includes:
step 100: and sending a first wake-up signal to the positioning equipment attached to the target to be positioned so as to enable the positioning equipment to send out a multi-dimensional signal.
It should be noted that the carrying manner of the positioning device can be three types: firstly, place on the target point position by artifical secret, secondly carry to the target top by unmanned aerial vehicle, thirdly carry to the target peripheral by small-size unmanned vehicle, awaken it again at specific time.
In addition, the outer surface of the positioning equipment can be sealed and wrapped by soft materials, so that the positioning equipment has certain functions of collision prevention and water prevention; the outer surface of the positioning device can be further provided with hooks and self-adhesive strips, so that the positioning device can be conveniently attached to the surface of a target, and the positioning device can be disguised as a common article and is conveniently and secretly placed on a target point position.
In the related art, a radar guidance or laser guidance mode is mostly adopted, however, the mode is easy to fail due to interference of electromagnetic wave frequency or influence of rainy, snowy and rainy weather, and thus the tracking of the target is not facilitated.
However, in the embodiment of the present specification, by knowing the target to be positioned in advance and then installing the positioning device on the target point, even if the target moves, a more accurate real-time position can be obtained.
In step 100, the multi-dimensional signal includes at least one of a beidou signal, an electromagnetic wave signal, and a laser signal. It is understood that the positioning device comprises a power supply assembly, a beidou directing assembly, an electromagnetic wave directing assembly and a laser directing assembly, the power supply assembly being adapted to provide electrical energy to the beidou directing assembly, the electromagnetic wave directing assembly and the laser directing assembly, respectively. The Beidou guiding component can comprise a Beidou positioning component, a Beidou communication component and a Beidou antenna, and has the main function of sending the precise position of the Beidou positioning component to the striking unit through the Beidou communication component, so that the Beidou guiding component is suitable for long-distance guiding (namely, a Beidou signal is sent through the Beidou guiding component); the electromagnetic wave guiding component can comprise a signal modulator, a radio frequency component and an electromagnetic wave antenna, and the main function is to indicate the target position by transmitting an encrypted electromagnetic wave signal, and the encrypted electromagnetic wave signal can also contain information such as the type, size and the like of the target (namely the electromagnetic wave signal is transmitted by the electromagnetic wave guiding component); the laser guide assembly may include a laser encoder, a laser emitter, and a laser emitting port, and the main function is to guide the precise striking (i.e., the laser signal is emitted through the laser guide assembly) in the direction of the missile flight.
In other embodiments, it may be also possible to trigger the positioning device to send out the multidimensional signal through a timing component disposed in the positioning device, where the timing component is configured to send out the multidimensional signal when the positioning device reaches a preset time.
Step 102: a multi-dimensional signal transmitted by a positioning device is received.
In some embodiments, the multi-dimensional signal may include any one of a Beidou signal, an electromagnetic wave signal and a laser signal, but it is difficult to effectively ensure the accuracy of the target position acquisition. In other embodiments, the multi-dimensional signals may include any two of a Beidou signal, an electromagnetic wave signal and a laser signal, and this way may improve the accuracy of the target position acquisition, i.e., reduce the interference of external factors, and provide higher stability. In still other embodiments, the multi-dimensional signals include a Beidou signal, an electromagnetic wave signal and a laser signal, which can effectively ensure the accuracy of the target position acquisition.
Certainly, it is worth explaining, when the multi-dimensional signal includes the beidou signal, as long as the terminal device can receive the beidou signal sent by the positioning device, the target position can be directly determined based on the beidou signal. That is, the Beidou signal has a higher priority than the other two signals.
In some embodiments, the multi-dimensional signal is emitted by:
detecting whether the Beidou signals can be reported to the terminal equipment or not by using the positioning equipment;
if yes, a Beidou signal is sent out by using positioning equipment;
if not, electromagnetic wave signals and/or laser signals are selectively emitted by the positioning device.
In this embodiment, the positioning device has a function of detecting whether the Beidou signal is successfully reported, and details of hardware components and software programs implemented by the function are not described herein, which are well known to those skilled in the art. Therefore, whether the positioning equipment reports the Beidou signal to the terminal equipment can be detected by using the function, and if the Beidou signal can be reported to the terminal equipment, the Beidou signal is sent by using the Beidou guide component; otherwise, the positioning device is used for selectively sending out electromagnetic wave signals and/or laser signals. The emission rule of the multi-dimensional signal is more reasonable, and the energy use of a power supply assembly can be saved.
The multidimensional signal corresponding to the embodiment includes the following combination modes: 1) the Beidou signals are included; 2) comprises an electromagnetic wave signal; 3) including a laser signal; 4) including electromagnetic wave signals and laser signals.
In some embodiments, the positioning device is thrown onto the target to be positioned by the unmanned aerial vehicle, the unmanned aerial vehicle is provided with a visual analysis component, and the visual analysis component is used for analyzing and obtaining type information and size information of the target to be positioned based on the acquired image of the target to be positioned;
the electromagnetic wave signal carries the type information and the size information of the target to be positioned, and the electromagnetic wave signal is encrypted.
In this embodiment, the unmanned aerial vehicle is an edge device with processing capability, that is, a target image acquired by, for example, a camera in real time may be utilized to analyze the target image (for example, a machine learning manner is utilized to analyze, which is not described herein) to obtain type information and size information of the target to be positioned. Therefore, the visual analysis component can send the obtained type information and the size information of the target to be positioned to the electromagnetic wave guidance component, so that the type information and the size information of the target to be positioned are mixed in the electromagnetic wave to be sent out, and the target to be positioned can be effectively analyzed. To further avoid interception of the electromagnetic wave, the electromagnetic wave signal may be subjected to an encryption process.
Step 104: based on the multi-dimensional signals, the position of the target to be positioned is determined.
In some embodiments, step 104 may include:
when the multi-dimensional signals comprise Beidou signals, the Beidou signals are analyzed, and the position of a target to be positioned is determined;
when the multi-dimensional signals comprise electromagnetic wave signals and/or laser signals, the position of the target to be positioned is determined based on the beam path of the electromagnetic wave signals and/or the beam path of the laser signals.
In this embodiment, if the multidimensional signal includes a beidou signal, the beidou signal needs to be analyzed to determine the position of the target to be positioned, and the analysis manner of the beidou signal is not described herein, which is well known to those skilled in the art. If the multi-dimensional signals comprise electromagnetic wave signals and/or laser signals, the position of the target to be positioned, namely the beam path of the electromagnetic wave signals and/or the beam path of the laser signals, needs to be determined according to the beam path of the electromagnetic wave signals and/or the beam path of the laser signals, so as to guide the missile (namely, provide a track for the missile).
In some embodiments, the positioning device is provided with an illumination sensor, the illumination sensor is used for acquiring illumination intensity information of an area where the target to be positioned is located, and the electromagnetic wave signal carries the illumination intensity information of the area where the target to be positioned is located;
when the multi-dimensional signal comprises an electromagnetic wave signal and a laser signal, determining the position of the target to be positioned based on a beam path of the electromagnetic wave signal and a beam path of the laser signal, comprising:
judging whether the beam path of the electromagnetic wave signal is the same as the beam path of the laser signal;
if the position of the target to be positioned is the same as the position of the target to be positioned, determining the position of the target to be positioned based on any one of the beam path of the electromagnetic wave signal and the beam path of the laser signal;
if not, then: analyzing the electromagnetic wave signal to obtain illumination intensity information carried in the electromagnetic wave signal; and if the illumination intensity information obtained by analysis indicates that the illumination intensity of the area where the target to be positioned is located is lower than a preset threshold value, determining the position of the target to be positioned based on the beam path of the electromagnetic wave signal.
In this embodiment, if the multi-dimensional signal includes an electromagnetic wave signal and a laser signal, it may be determined whether a beam path of the electromagnetic wave signal is the same as a beam path of the laser signal (where the scheme of determining the paths is well known by those skilled in the art and is not described here in detail), and if the two paths are the same, the position of the target to be positioned may be determined by using the beam path of the electromagnetic wave signal, or the position of the target to be positioned may be determined by using the beam path of the laser signal. If the two are different, analyzing the electromagnetic wave signal to obtain illumination intensity information carried in the electromagnetic wave signal; and if the illumination intensity information obtained by analysis indicates that the illumination intensity of the area where the target to be positioned is lower than a preset threshold (indicating that the weather of the area where the target to be positioned is rainy, snowy and unfavorable for detection of the laser signal), determining the position of the target to be positioned based on the beam path of the electromagnetic wave signal.
Of course, if the two are different, it can also be performed: analyzing the electromagnetic wave signal, detecting whether an interference source exists in the electromagnetic wave signal (wherein, the scheme for determining whether the interference source exists is well known by those skilled in the art and is not described herein), and if so, determining the position of the target to be positioned based on the beam path of the laser signal.
Thus, the position of the target to be positioned can be accurately determined based on the beam path of the electromagnetic wave signal and the beam path of the laser signal.
In some embodiments, the above method further comprises:
sending a second wake-up signal to the positioning equipment to trigger the self-explosion component of the positioning equipment; wherein, the auto-explosion subassembly is used for exploding the positioning device when triggering.
In this embodiment, since there may be information that an enemy wants to obtain in the positioning device, in order to eliminate the action trace, a self-explosive component (e.g. a small bomb) may be provided in the positioning device, so that the terminal device triggers the self-explosive component of the positioning device by sending a second wake-up signal to the positioning device, so that the self-explosive component explodes the positioning device when triggered.
In summary, in the above technical solution, a positioning device is first attached to an object to be positioned, and then a first wake-up signal is sent to the positioning device, so that the positioning device can send a multidimensional signal, and then the multidimensional signal sent by the positioning device is received, so as to determine a position of the object to be positioned based on the multidimensional signal; wherein, this dimension signal includes at least one in big dipper signal, electromagnetic wave signal and laser signal. Therefore, the scheme is not limited to positioning the target by the single-dimensional signal, but the target is positioned based on the multi-dimensional signal, so that the accurate position of the target can be effectively obtained.
It can be understood that the above target positioning method based on multi-dimensional signals can be used for military guidance striking and also for civil communication.
