[0025] See Figure 1 , Figure 2 and Figure 3As shown, this application proposes a radar control board, comprising: an FPGA processing unit, which is communicatively connected to a linear array laser and a detector; a power supply, which is electrically connected to the FPGA processing unit, the linear array laser, and the detector; an RS422 unit, which is communicatively connected to the FPGA processing unit; a network unit, which is communicatively connected to the FPGA processing unit; and a protective structure, in which the FPGA processing unit is disposed.

[0026] FPGA processing units are a further development based on devices such as programmable array logic, general-purpose array logic, and erasable programmable logic devices. An FPGA processing unit is a programmable logic chip capable of performing general-purpose functions; that is, it can be programmed to implement specific logic processing functions. The FPGA processing unit primarily handles linear laser control, receiving echo signals from the detector, calculating distance and spatial coordinates, and outputting point cloud data.

[0027] The FPGA processing unit exhibits excellent stability and reliability, enabling stable operation in various complex environments and ensuring the normal functioning of the LiDAR system. Furthermore, the FPGA processing unit possesses powerful data processing capabilities, efficiently processing large amounts of data acquired by the linear laser array and detectors, and achieving high-precision distance measurement and environmental perception.

[0028] The power supply provides power to the FPGA processing unit, detector, and linear laser array. The network unit uses a PHY chip to communicate with the FPGA processing unit through the RGMII interface to complete the point cloud data transmission. The RS422 unit uses an isolated RS422 chip to implement the RS422 communication interface and receive external commands to realize the communication function.

[0029] The protective structure is designed to prevent external environmental factors from affecting the FPGA processing unit, thereby further improving the stability and reliability of the radar control board.

[0030] Specifically, by using an FPGA processing unit, which possesses excellent stability and reliability, it can operate stably in various complex environments, ensuring the normal operation of the lidar system. Furthermore, the FPGA processing unit has powerful data processing capabilities, efficiently processing the large amounts of data collected by the linear laser array and detectors, and achieving high-precision distance measurement and environmental perception. A protective structure prevents external environmental influences on the FPGA processing unit, further enhancing the stability and reliability of the radar control board.

[0031] See Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the protective structure includes: a protective housing 1 with an opening at its upper end; a storage space formed inside the protective housing; a circuit board 5 disposed within the protective housing 1, with electrical components 7 mounted on the circuit board 5; the circuit board 5 is placed in the storage space within the protective housing 1, and a second fastener is provided on the circuit board 5 for securely mounting the circuit board 5 into the protective housing 1; an FPGA processing unit is integrated onto the circuit board 5; preferably, both the RS422 unit and the network unit are integrated onto the circuit board 5; and the electrical components 7 constitute the FPGA processing unit. A power supply is also preferably disposed within the protective housing. A cover plate 2 is disposed within the protective housing 1. The cover plate 2 is used to seal the storage space and prevent the FPGA processing unit from being affected by the external environment.

[0032] See Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the protective structure further includes: several heat dissipation layers disposed on the cover plate 2, the heat dissipation layers including a steel layer 8 and an aluminum layer 9 connected to the steel layer 8, the aluminum layer 9 contacting the electrical component 7. To ensure the protective performance of the protective enclosure 1, no heat dissipation vents are provided on the protective enclosure 1 except for the connection interface 4. During the operation of the radar control board, heat is transferred to the steel layer 8 through the aluminum layer 9, and then to the cover plate 2. The heat is dissipated from the radar control board through heat exchange between the cover plate 2 and the external environment. By providing the aluminum layer 9, damage to the electrical components by the heat dissipation layer can be effectively avoided.

[0033] In this embodiment, the cover plate 2 is provided with spaced heat dissipation protrusions to enhance the heat dissipation efficiency of the cover plate 2. Alternatively, several heat dissipation protrusions can be provided on the protective housing 1. Since the heat generated by the electrical components can also be transferred to the protective housing 1 through the air, providing heat dissipation protrusions on the protective housing 1 is beneficial to enhancing the overall heat dissipation performance of the protective structure.

[0034] See Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the protective structure further includes a first fastener 3, through which the cover plate 2 is mounted to the protective housing 1. The first fastener 3 is preferably a screw, which securely connects the protective housing 1 to the cover plate 2. The protective housing 1 is provided with threaded holes 6 adapted to the first fastener 3.

[0035] See Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, in some embodiments, the protective structure further includes: a stepped groove, wherein the protective housing 1 is provided with a stepped groove; and a stepped protrusion 10, wherein the cover plate 2 is provided with a stepped protrusion 10 adapted to the stepped groove. The stepped groove and the stepped protrusion 10 enhance the sealing performance between the cover plate 2 and the protective housing 1, preventing dust or moisture from the external environment from entering the protective housing 1.

[0036] See Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments, the protective structure further includes a sealing gasket 11, which is disposed on the stepped groove. The sealing gasket 11 is used to further enhance the sealing performance between the cover plate 2 and the protective housing 1, preventing dust or moisture from the external environment from entering the protective housing 1.
