Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and specifically to an anti-interference communication device. Background Technology

[0002] In the field of modern communications, with the widespread application of communication technologies and the increasing complexity of communication environments, signal interference has become one of the key factors affecting communication quality and reliability. Whether in wireless communication networks, military communication systems, or industrial control communications, interference signals can lead to serious problems such as communication interruptions and data errors.

[0003] In wireless communication, communication signals are affected by various interference sources from all directions. For example, in urban environments, the electromagnetic environment becomes extremely complex due to numerous wireless devices, electronic devices, and building reflections. In such situations, omnidirectional antennas, which can receive and transmit signals in all directions, are prone to receiving a large amount of interference signals, thereby degrading communication quality.

[0004] Some existing communication devices are inadequate in their anti-interference capabilities. Some devices lack specific measures to reduce the reception of interference signals from non-target directions. For long-distance communication, such as microwave communication links, the signal needs sufficient strength to overcome path loss during transmission, but it is also more susceptible to interference from the surrounding environment. If traditional antenna designs cannot effectively control the transmission and reception directions of the signal, the useful signal may be overwhelmed by interference signals during long-distance communication, leading to communication failure.

[0005] Therefore, in order to improve the anti-interference capability of communication devices in signal reception and transmission, more and more wireless communication devices are beginning to adopt various forms of directional antennas to achieve long-distance communication and enhance communication signals and anti-interference capabilities in a certain direction.

[0006] However, in the existing technology, most directional antennas, whether fixed indoors or installed outdoors, are fixed in one location. This allows for long-term communication between two fixed communication devices in opposite directions, but when switching communication directions or between communication devices in different directions, manual adjustment by the operator is often required. Utility Model Content

[0007] The purpose of this invention is to provide an anti-interference communication device that solves the problem that most communication devices use fixed-installation directional antennas, which are not convenient for adjusting the direction as the communication device is switched.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] An anti-interference communication device includes a communication-connected device body and an antenna module. The antenna module includes a base, a mounting cavity is provided inside the base, a drive motor is provided inside the mounting cavity, the output shaft of the drive motor extends out of the upper side of the base and is connected to a horizontal plate, a directional antenna is vertically mounted on the horizontal plate, and the directional antenna is communication-connected to the device body.

[0010] A further technical solution is that a vertical plate is installed on the upper side of the horizontal plate, a directional antenna is installed on the front side of the vertical plate, and a left shielding plate and a right shielding plate are installed on the left and right sides of the vertical plate respectively.

[0011] A further technical solution is that both the left and right shielding plates are horizontally connected to the vertical plate via a rotating shaft. A drive block is installed on the rear side of the vertical plate, and a first electric telescopic rod and a second electric telescopic rod are installed on the drive block. The telescopic end of the first electric telescopic rod is movably connected to the right side of the left shielding plate, and the telescopic end of the second electric telescopic rod is movably connected to the left side of the right shielding plate.

[0012] A further technical solution is that a connecting piece is horizontally arranged on the right side of the left shielding plate, and an elongated hole is provided on the connecting piece that runs through the upper and lower sides. A connecting shaft is slidably arranged in the elongated hole, and the connecting shaft is connected to the telescopic end of the first electric telescopic rod.

[0013] A further technical solution is to place the first electric telescopic rod and the second electric telescopic rod on the upper and lower sides of the drive block, respectively.

[0014] A further technical solution is to provide a support rail on the upper side of the base, with the upper side of the support rail slidingly fitting against the lower side of the horizontal plate.

[0015] A further technical solution is that the left side of the base is provided with an inspection hole that communicates with the mounting cavity, and an inspection door for sealing the inspection hole.

[0016] A further technical solution is to have a mounting plate on the rear side of the base, with fixing holes running through both sides on the mounting plate.

[0017] Compared with existing technologies, this utility model has at least one of the following beneficial effects: 1. By using a directional antenna, signal transmission and reception in a certain direction can be enhanced, while signal interference in other directions can be reduced, increasing transmission distance, reducing interference, and improving signal quality; 2. By setting a drive motor, a horizontal plate can be rotated, and the orientation of the directional antenna can be adjusted according to the requirements of matching signal transmission or reception sources in different directions. This solves the problem that most communication devices use fixed installation for their directional antennas, making it inconvenient to adjust the direction as the communication device is switched.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Figures 1 to 3 The following is an embodiment of the present invention.

[0024] Example 1:

[0025] An anti-interference communication device includes a communication-connected device body 1 and an antenna module. The antenna module includes a base 2, a mounting cavity 3 within the base 2, and a drive motor 4 within the mounting cavity 3. The output shaft of the drive motor 4 extends through the upper side of the base 2 and is connected to a horizontal plate 5. A directional antenna 6 is vertically mounted on the horizontal plate 5 and is communication-connected to the device body 1. The directional antenna 6 enhances signal transmission and reception in a specific direction while reducing signal interference from other directions, increasing transmission distance, reducing interference, and improving signal quality. The drive motor 4 rotates the horizontal plate 5, which in turn adjusts the orientation of the directional antenna 6, allowing it to be aligned with different signal transmission or reception sources as needed. This solves the problem that most communication devices use fixed-mount directional antennas 6, making it inconvenient to adjust their orientation during communication device switching.

[0026] The main body of the device 1 can adopt a conventional wireless communicator structure, generally including: a radio frequency (RF) module. Function: The RF module is mainly responsible for processing high-frequency signals. It consists of an RF transmitter and an RF receiver. The RF transmitter modulates, up-converts, and amplifies the baseband signal (low-frequency signal), converting it into a high-frequency RF signal suitable for propagation in space. The RF receiver performs the opposite operation, filtering, down-converting, and demodulating the received high-frequency RF signal to restore it to the baseband signal. Components: Modem: Used for signal modulation and demodulation. Modulation is the process of loading information from the baseband signal onto a high-frequency carrier signal, carrying information by changing the amplitude, frequency, or phase of the carrier. The demodulator extracts the original baseband signal from the received modulated signal. Power amplifier and low-noise amplifier: The power amplifier enhances the signal power at the transmitting end, enabling the signal to be transmitted over long distances with sufficient strength. The low-noise amplifier amplifies weak signals at the receiving end while minimizing introduced noise. Filter: The filter allows signals of specific frequency bands to pass through while suppressing signals of other frequency bands. In wireless communication devices, there are various types of filters, such as bandpass filters, low-pass filters, and high-pass filters.

[0027] Baseband Processing Module Function: The baseband processing module is primarily responsible for processing digital baseband signals. It performs signal encoding, decoding, multiplexing, and demultiplexing operations, and is the core component for implementing communication protocols and data processing. Components: Digital Signal Processor (DSP): A DSP is a chip specifically designed for digital signal processing. It can quickly execute complex mathematical operations, such as Fourier transforms and filtering algorithms, and is used for signal modulation / demodulation, encoding / decoding, and other processing. Microprocessor (MCU) or Central Processing Unit (CPU): Used to control and coordinate the various components of the wireless communication device, execute the communication protocol stack software, and process data from upper-layer application programs.

[0028] Power Management Module: The power management module is responsible for providing a stable power supply to all components of the wireless communication device. It ensures that each component operates under appropriate voltage and current, and also performs power distribution and energy-saving control functions. Components: Battery or External Power Interface: This is the device's power source. For mobile devices, the battery is the primary power source, and its capacity and performance directly affect the device's battery life. The external power interface is used to connect a charger or other external power source to charge the device or provide direct power. Voltage Regulator and Power Converter: The voltage regulator maintains a stable output voltage, preventing voltage fluctuations from damaging device components. The power converter converts the input power voltage to the operating voltage required by different components. For example, in a laptop, the power management module can convert the voltage provided by the external power adapter to a suitable operating voltage for different components such as the motherboard, hard drive, and wireless network card.

[0029] User Interface Module: The user interface module is used to enable interaction between the user and the wireless communication device. It includes input and output devices, facilitating user operation of the device and acquisition of communication information. Components: Input devices: such as buttons, touchscreen, microphone, etc. Buttons are used for simple operation command input, touchscreens provide a more intuitive and flexible operation method, and microphones are used for voice input, such as voice calls and voice control functions. Output devices: such as displays, speakers, indicator lights, etc. Displays are used to display text, images, video, and other information, speakers are used to play sound, and indicator lights can display the device's working status, such as signal strength and charging status. The above is an overview of the functional components of existing wireless communication devices, without any improvements to these functional modules; details not covered are omitted.

[0030] Example 2:

[0031] Based on Embodiment 1, a vertical plate 7 is vertically installed on the upper side of the horizontal plate 5, and a directional antenna 6 is installed on the front side of the vertical plate 7. A left shielding plate 8 and a right shielding plate 9 are respectively installed on the left and right sides of the vertical plate 7. By setting the left shielding plate 8 and the right shielding plate 9, they can serve as shielding plates for the directional antenna 6, further reducing signal interference from both left and right directions and improving the anti-interference capability of the antenna module.

[0032] Both the left shielding plate 8 and the right shielding plate 9 are horizontally rotatably connected to the vertical plate 7 via a rotating shaft 10. A drive block 11 is installed on the rear side of the vertical plate 7, and a first electric telescopic rod 12 and a second electric telescopic rod 13 are mounted on the drive block 11. The telescopic end of the first electric telescopic rod 12 is movably connected to the right side of the left shielding plate 8, and the telescopic end of the second electric telescopic rod 13 is movably connected to the left side of the right shielding plate 9. Using the first electric telescopic rod 12 and the second electric telescopic rod 13, the angles of the left shielding plate 8 and the right shielding plate 9 can be adjusted, allowing them to form different angles. This adjusts the angle of the receiving direction of the directional antenna 6, further improving the anti-interference capability of signals in a given direction during signal transmission and avoiding interference from signals in other directions. Furthermore, when establishing communication with multiple signal sources simultaneously, the angle of the receiving direction of the directional antenna 6 can be controlled by adjusting the left shielding plate 8 and the right shielding plate 9, keeping multiple signal sources within this angle and keeping other unwanted signal sources outside the angle.

[0033] A connecting piece 14 is horizontally arranged on the right side of the left shielding plate 8. The connecting piece 14 has an elongated hole 15 that runs through both the upper and lower sides. A connecting shaft 16 is slidably arranged in the elongated hole 15. The connecting shaft 16 is connected to the telescopic end of the first electric telescopic rod 12. By setting the connecting piece 14 and the elongated hole 15, the connecting shaft 16 has sufficient room to move when the first electric telescopic rod 12 extends and retracts, and will not cause jamming.

[0034] The first electric telescopic rod 12 and the second electric telescopic rod 13 are respectively located on the upper and lower sides of the drive block 11. The right shielding plate 9 and the second electric telescopic rod 13 are connected in the same way as the first electric telescopic rod 12 and the left shielding plate 8.

[0035] A support rail 17 is provided on the upper side of the base 2, and the upper side of the support rail 17 slides and fits against the lower side of the horizontal plate 5. By providing the support rail 17, the horizontal plate 5 can be supported, making the horizontal plate 5 rotate more smoothly and preventing it from tilting.

[0036] The left side of the base 2 is provided with an inspection hole 18 that communicates with the mounting cavity 3, and an inspection door for closing the inspection hole 18. The inspection hole 18 and the inspection door facilitate the maintenance or adjustment of the drive motor 4.

[0037] A mounting plate 19 is provided on the rear side of the base 2, and the mounting plate 19 has fixing holes 20 that pass through both sides. By providing the mounting plate 19 and fixing holes 20, it is easy to install the base 2 on a wall or mounting rod.
