Description

Technical Field

[0001] The utility model relates to the technical field of receiver anti-interference, and particularly relates to an anti-interference component for a Beidou navigation receiver. Background Technique

[0002] In the communication field, external interference refers to the strong electromagnetic field interference from various electromagnetic radiations and power equipment, etc., which will cause signal transmission distortion and loss. Signal anti-interference technology is to reduce the influence of electromagnetic interference through measures, such as increasing the signal-to-noise ratio, using high-level coding and modulation technologies, etc., so as to ensure the quality and stability of signal transmission.

[0003] During the transmission of existing Beidou satellite signals, they will be affected by various different interferences. Electromagnetic interference is one of the most common interferences in the communication process, which is divided into man-made interference and natural interference. Natural interference mainly comes from the atmospherics in the atmosphere, cosmic noise in the outer space of the earth, and due to the revolution and rotation of the earth, the earth's internal magnetic field is constantly changing, which will all bring certain interference to the signal transmission. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-interference component for a Beidou navigation receiver to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-interference component for a Beidou navigation receiver, including an installation base, a support column is installed at the center position of the upper end of the installation base, a limiting plate is installed at the upper end of the support column, six antenna bodies are installed in a hexagonal array at the edge position of the upper end of the limiting plate, six installation slots are installed in a hexagonal array at the position of the upper end of the installation base outside the support column, a signal receiver is installed inside the installation slot, the six signal receivers and the six antenna bodies are electrically connected in sequence, a signal converter and a processor are arranged inside the installation base, the signal converter, the processor and the signal receiver are electrically connected, and the processor and the receiver are electrically connected.

[0006] Preferably, a rectangular antenna array is installed at the upper end outside the antenna body.

[0007] Preferably, a time-domain filter is arranged inside the signal receiver.

[0008] Preferably, six limiting slots are formed on the surface of the limiting plate, and the limiting slots and the processor are arranged in correspondence with each other.

[0009] Preferably, six antenna interfaces are installed in an array at the position outside the limiting slots at the upper end of the limiting plate.

[0010] Preferably, a plurality of aluminum sheets are mounted on the surface of the processor.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For this Beidou navigation receiver anti-interference component, by electrically connecting the mounting base and the receiver, six antennas will receive and transmit the signals to the corresponding signal receivers. During the signal transmission process, different interference signals will be generated according to different magnetic fields, resulting in different interference signals received by the six antennas. The six signal receivers transmit the six groups of signals to the signal converter for compilation and conversion, and the converted signals are transmitted to the processor for comparison and processing. The processor retains the signals with the same frequency among the six groups of signals. The signal received by a single signal receiver is easily interfered by the magnetic field and thus generates irrelevant interference signals. Multiple signal receivers receive synchronously, and the received interference signals are all different. Through the comparison and processing by the processor, only the signals with the same frequency are retained, which can retain and receive the required signals to a large extent. Due to the magnetic field changes caused by the rotation and revolution of the earth, the problem of unstable signal reception caused by signal attenuation and interference brought about by magnetic field changes can be reduced.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0020] As Figures 1 to 4 shown, the anti-interference component of the Beidou navigation receiver in this embodiment includes a mounting base 1. A support column 7 is installed at the center position of the upper end of the mounting base 1. The support column 7 is at the center position of the upper end of the mounting base 1. A limit plate 8 is installed at the upper end of the support column 7. Six antenna bodies 3 are installed in a hexagonal array at the edge position of the upper end of the limit plate 8. There is a detachable connection relationship between the antenna body 3 and the limit plate 8. Six mounting grooves 6 are installed in a hexagonal array at the position outside the support column 7 on the upper end of the mounting base 1. A signal receiver 2 is installed inside the mounting groove 6. There is a clamping connection relationship between the signal receiver 2 and the mounting groove 6. The six signal receivers 2 and the six antenna bodies 3 are electrically connected in sequence. Each signal receiver 2 is individually electrically connected to an antenna body 3. A signal converter and a processor are arranged inside the mounting base 1. The signal converter, the processor and the signal receiver 2 are electrically connected. The processor and the receiver are electrically connected. Multiple signal receivers 2 receive synchronously. The received interference signals are all different. Through comparison and processing by the processor, only the signals with the same frequency are retained, which can retain and receive the required signals to a large extent and reduce the signal instability caused by electromagnetic interference.

[0021] Specifically, a rectangular antenna array 4 is installed at the upper end outside the antenna body 3. The directivity of a single antenna is limited. To suit the applications in various scenarios, two or more single antennas operating at the same frequency are fed and arranged in space according to certain requirements to form an antenna array, also called an antenna array, which can enhance and improve the directivity of the radiation field and enhance the intensity of the radiation field.

[0022] Furthermore, a time-domain filter is arranged inside the signal receiver 2. The time-domain filter can reduce the influence of multipath and scattered signals on the Beidou signal and at the same time reduce the influence of narrowband interference.

[0023] Further, six limiting grooves 10 are formed on the surface of the limiting plate 8. The limiting grooves 10 and the processor are arranged in correspondence with each other. Six antenna interfaces 9 are array-mounted at the position of the upper end of the limiting plate 8 outside the limiting grooves 10. By using the limiting grooves 10 and the processor in cooperation, the processor will be limited inside the limiting grooves 10, and at the same time, the limiting plate 8 can play a certain protective role for the processor.

[0024] Furthermore, a plurality of aluminum sheets 5 are mounted on the surface of the processor. Through the reinforced metal structure of the aluminum sheets 5, the interference of external artificial electromagnetic signals on the signal receiver 2 can be weakened to a certain extent.

[0025] The usage method of this embodiment is as follows: By electrically connecting the mounting base 1 with the receiver, six antennas will receive and transmit the signals to the corresponding signal receivers 2. During the signal transmission process, different interference signals will be generated according to different magnetic fields, resulting in different signal interferences received by the six antennas. The six signal receivers 2 transmit six groups of signals to the signal converter for compilation and conversion, and the converted signals are transmitted to the processor for comparison and processing. The processor retains the signals with the same frequency in the six groups of signals. The signals received by a single signal receiver 2 are easily interfered by the magnetic field and thus generate irrelevant interference signals. The multiple signal receivers 2 receive signals synchronously, and the received interference signals are all different. Through the comparison and processing by the processor, only the signals with the same frequency are retained, which can retain and receive the required signals to a large extent. Because the magnetic field changes due to the rotation and revolution of the earth, the problem of unstable signal reception caused by signal attenuation and interference caused by magnetic field changes can be reduced.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
