[0032] In order to make the technical problems, technical schemes and beneficial effects to be solved by the utility model more clear and obvious, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and do not limit the utility model.

[0033] As Figure 1 shown, the application provides an automatic adjustment anti-interference intercom, which integrates spectrum analysis device 2, automatic adjustment circuit 3, control processor 4, display and operation interface 5, power management circuit 7 and antenna system 6 in wireless communication system 1, realizes the automatic adjustment of the anti-interference ability under the complex electromagnetic environment, and thus guarantees the stability of communication quality. The following is the specific implementation manner of the application, which combines the detailed description of the functions and interactions of each component.

[0034] The wireless communication system 1 is the core part of the application, responsible for the transmission and reception of the intercom signals. It includes a transmitter 11 and a receiver 12, where the transmitter 11 is responsible for converting the processed electrical signals into radio frequency signals and transmitting them into the air through the transmitting antenna 61, and the receiver 12 is responsible for receiving the radio frequency signals transmitted by other intercoms or communication devices and converting them into electrical signals for subsequent processing. The working of the transmitter 11 and the receiver 12 is based on the principle of modulation and demodulation of radio frequency signals to ensure efficient transmission and reception of signals in a wireless environment.

[0035] As shown in Figure 1 , the spectrum analysis device 2 is the basis for automatic adjustment of anti-interference, mainly composed of a spectrum analyzer 21 and an interference identifier 22. The spectrum analyzer 21 is used to scan the frequency characteristics of the current working frequency band in real time, and obtain the spectrum data of the received wireless signals. By analyzing these data, the interference source in the signal and the strength of the interference can be quickly identified. The interference identifier 22 classifies different types of interference according to the spectrum data, including electromagnetic interference (EMI), co-channel interference and multi-path interference, etc. Through these real-time interference information, the system can dynamically evaluate the quality of the current communication environment and provide necessary data support for subsequent signal optimization.

[0036] The automatic adjustment circuit 3 includes a frequency switching circuit 31 and a power adjustment circuit 32. The frequency switching circuit 31 automatically selects the backup frequency band with the least interference according to the interference information from the spectrum analysis device 2, and switches the intercom to this frequency band to ensure the clarity and stability of the signal. The power adjustment circuit 32 dynamically adjusts the transmission power of the signal according to the real-time monitored interference strength. When strong interference is detected, the power adjustment circuit 32 will automatically reduce the transmission power to avoid excessive interference and prolong the battery life; when the interference is small or the signal quality is poor, the power adjustment circuit 32 enhances the signal transmission to ensure the effectiveness of the communication. Through these automatic adjustment functions, the embodiment can maintain good communication quality in different electromagnetic environments without manual intervention.

[0037] The control processor 4 includes a microprocessor 41 and a memory 42. The microprocessor 41 is responsible for processing the interference data from the spectrum analysis device 2, and calculating the best frequency switching and power adjustment parameters according to the interference type and strength. The memory 42 is used to store historical interference data, preset frequency adjustment rules and real-time parameters in operation. The control processor 4 decides whether to switch the frequency band or adjust the transmission power according to the spectrum analysis and real-time signal conditions, and sends the instructions to the wireless communication system 1, the frequency switching circuit 31 and the power adjustment circuit 32 through the control bus, to complete the dynamic adjustment of the system.

[0038] To provide a better user experience, the display and operation interface 5 includes a liquid crystal display screen 51 and a touch screen 52. The liquid crystal display screen 51 is used to display the working status of the device in real time, such as the current signal strength, working frequency band, interference type, battery level, etc. information, so that the user can understand the running status of the device. The touch screen 52 serves as the interaction interface between the user and the device, and the user can select the working mode, such as the interference detection mode or the automatic adjustment mode, through touch operation. In the "interference detection mode", the device will focus on the monitoring and analysis of the interference source, while in the "automatic adjustment mode", the device will automatically adjust according to the interference situation in the environment to ensure the best communication state.

[0039] The power management circuit 7 provides stable power output to ensure the normal operation of each component. Through efficient power management, the system can dynamically adjust power distribution according to different working states, ensuring that the wireless communication system 1, the spectrum analysis device 2, the automatic adjustment circuit 3, the control processor 4 and the display interface can all obtain sufficient power support, thereby prolonging the battery usage time and ensuring that the device will not run out of power in a long time.

[0040] The antenna system 6 includes a transmitting antenna 61 and a receiving antenna 62, which are used to optimize the transmission and reception of signals. The transmitting antenna 61 is responsible for effectively transmitting the radio frequency signals output by the transmitter 11 into the air, while the receiving antenna 62 receives the radio frequency signals from the air and transmits them to the receiver 12. The design of the antenna takes into account the propagation distance, signal strength and environmental factors of the signal to ensure that high-quality communication can be maintained in a complex electromagnetic environment.

[0041] As shown in Figure 1 The working principle of the present application is as follows.

[0042] When the intercom is in working state, the spectrum analysis device 2 will continuously monitor the surrounding electromagnetic environment and analyze the received wireless signals to identify the interference source in real time. The control processor 4 determines whether to switch the working frequency band or adjust the signal power according to the analysis results. If the interference is large, the frequency switching circuit 31 will automatically select a backup frequency band with less interference to ensure uninterrupted communication. If the interference is small, the power adjustment circuit 32 will appropriately enhance the transmission power to expand the signal coverage. At the same time, the display and operation interface 5 shows the user the real-time communication state, and the user can select the appropriate working mode through the touch screen 52.

[0043] In summary, through the automatic adjustment anti-interference intercom of the present application, the device can automatically identify and cope with different types of interference in a complex electromagnetic environment, thereby ensuring communication quality. The close cooperation of the automatic adjustment circuit 3, the spectrum analysis device 2, and the control processor 4 ensures that the device can provide reliable and stable communication services in a real-time changing environment. This system not only greatly simplifies user operation and reduces human intervention, but also effectively improves the energy efficiency and service life of the device, and is particularly suitable for applications against strong electromagnetic interference.

[0044] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned manner. As long as various non-essential improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model is directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
