Description

Technical Field

[0001] This invention relates to the field of new energy transportation and microwave technology interference shielding, specifically to a microwave transmission wireless system integrated into a photovoltaic corridor and its impact on the internal and external environment of the corridor, including interference-free communication equipment in electric vehicles on the corridor side. Background Technology

[0002] Photovoltaic new energy has become the main energy source for society, and new energy electric vehicles are developing rapidly. 1. Wireless charging in photovoltaic corridors generates electromagnetic waves that affect or interfere with the normal wireless application of the environment inside and outside the corridor, causing interference from drones and radio outside the corridor, as well as affecting the normal navigation and communication needs of electric vehicles. This paper combines and solves the problem of interference-free microwave dynamic transmission technology, and adopts shielding while penetrating directional wireless antennas to enhance the efficiency of normal use of vehicle navigation and communication. 2. Existing microwave wireless charging systems have low efficiency (<85%) and lack anti-interference design for the vehicle environment; 3. The power and frequency of the vehicle-mounted receiver affect the stability of vehicle-mounted communication. Technological gap: The application of photovoltaic corridor microwave wireless charging technology can shield the environment from interference while ensuring the normal operation of vehicle navigation and communication applications. Summary of the Invention

[0003] Technical solution

[0004] The technical problem solved by this invention can be achieved by the following technical solutions:

[0005] The impact mechanism of the metal mesh shielding of the system corridor on vehicle communication:

[0006] This patent, through a combination of material innovation and intelligent control, fills the technological gap in refined protection of photovoltaic corridors, significantly improving power plant safety and operation and maintenance efficiency. Further technical details or experimental data can be provided in the form of detailed embodiments and test reports.

[0007] The closed shielding structure formed by the metal mesh blocks external electromagnetic waves from entering the corridor, while simultaneously suppressing the outward propagation of electromagnetic waves generated by internal equipment (such as inverters). This two-way shielding characteristic may lead to a significant attenuation of wireless signal strength (such as 4G / 5G, Wi-Fi, GPS) within the corridor.

[0008] Wave-transparent antenna

[0009] Key Innovation Points: Interference Analysis in Key Frequency Bands 1. High-frequency signals (such as 5GHz WiFi, 4G / 5G): The mesh size of the metal mesh needs to be much smaller than the signal wavelength (e.g., 6cm for 5GHz). High mesh count shielding mesh (e.g., 120 mesh or more) will significantly block the transmission of high-frequency signals. 2. Low-frequency signals (such as FM radio, car radio): Low-frequency signals have longer wavelengths (such as FM 10 MHz corresponding to a wavelength of 3 meters), and are less affected by metal mesh shielding, but the overall structure may still cause the signal to weaken. 3. Differences in communication equipment types In-vehicle navigation (GPS): relies on satellite signals, and signal reception may be completely blocked when the metal mesh is completely closed. Cellular networks (4G / 5G): Signal attenuation may cause network delays or disconnections, especially in long corridors.

[0010] Technical effect

[0011] Engineering and technical measures to mitigate the impact on communications 1. Wave transmission window design Directional wave-transmitting material: Ceramic-based wave-transmitting material or dielectric antenna window is embedded in a specific location of the shielding mesh to allow the target frequency band (such as 2.4GHz WiFi, 5G frequency band) to penetrate, and the insertion loss of the wave-transmitting window is controlled to ≤1dB. Frequency band customization: Select the transparent frequency band according to the communication needs within the corridor, such as reserving a dedicated channel for vehicle-to-everything (V2X). 2. Optimized design of shielding mesh Gradient mesh count configuration: The top uses a high-mesh-count copper mesh to suppress high-frequency interference, while the side walls use a low-mesh-count stainless steel mesh to reduce the impact on low-frequency signals. Modular adjustable structure: The mesh density is dynamically adjusted via an electric slide rail, allowing some areas to be opened during off-peak hours to restore communication signals. 3. Enhance the performance of communication equipment Vehicle-mounted repeaters: These are signal amplifiers deployed inside vehicles to enhance the reception of external signals and compensate for attenuation caused by shielding. Wired communication backup: Fiber optic or power line carrier communication lines are pre-buried in the corridor to provide redundant channels for critical equipment (such as emergency communications). 4. Grounding and Electromagnetic Compatibility Management Single-point grounding: The shielding mesh adopts centralized single-point grounding to avoid potential difference interference introduced by multi-point grounding, and the grounding resistance is ≤4Ω. 5. Isolation transformer and filter: An isolation transformer and low-pass filter are installed at the communication line access point to suppress high-frequency harmonic interference.
