[0028] In order to solve the technical problems existing in the prior art, the basic concept of the utility model is to set the power module on an independent power board, so as to reduce the size of a single power board and a main control board, which is beneficial to reducing the area occupied by the wireless networking communication device during installation. At the same time, since the power board is installed on the side wall of the installation box that is not the installation wall, it is also beneficial to the heat dissipation of the power board.

[0029] Specific embodiments of the wireless networking communication device provided by the utility model:

[0030] A wireless networking communication device, see attached Figure 1 and attached Figure 2 , including mounting box and carrier plate.

[0031] The installation box includes a box body 1 and a cover body 2 made of metal. The box body 1 is a hollow rectangular parallelepiped structure with an opening on one side. The cover body 2 is fixedly installed at the opening of the box body 1 by bolts. The bottom wall of the box body 1 is a mounting wall. The outer edge of the mounting wall is provided with a mounting ear 3. The mounting ear 3 is provided with a bolt hole for the bolt to pass through. When in use, the mounting wall is abutted against the equipment that needs to communicate in the cabin, and the mounting box is fixedly connected to the corresponding equipment by bolts.

[0032] See attached Figure 3 and attached Figure 4 The carrier board includes a main control board 4, a power board 5 and two radio frequency boards 6. The main control board 4 and the power board 5 are both located inside the installation box. The main control board 4 is fixedly mounted on the bottom wall of the box body 1 by bolts, and the power board 5 is fixedly mounted on the inner side of the cover body 2 by bolts, so that the power board 5 and the main control board 4 are arranged parallel to each other, so that the length and width of the installation box are small, which is convenient for flexible use and installation in the cabin.

[0033] The main control board 4 is provided with a signal processing module, which includes an Ethernet signal processing circuit and a SOC, and the power board 5 is provided with a power module. The outer side of the cover 2 is provided with a heat dissipation fin 7, and the heat generated by the power module during use can be dissipated in time through the cover 2 and the heat dissipation fin 7 on the cover 2 to prevent heat accumulation from causing the temperature to rise and affect the normal operation of the wireless networking communication device.

[0034] The RF board 6 is provided with a baseband processing chip, a RF transceiver chip and an antenna unit. The antenna unit in this embodiment is an array antenna arranged on the RF board 6. The two RF boards 6 are both located outside the installation box and fixedly mounted on two opposite side walls of the box body 1 by bolts. The two RF boards 6 are arranged back to back and are perpendicular to the installation wall.

[0035] Two wave-transmitting protective covers 8 corresponding to the radio frequency boards 6 are fixedly installed on the outer side of the installation box by bolts. The wave-transmitting protective covers 8 cover the corresponding radio frequency boards 6 to play a protective role.

[0036] A power connector 9 and a signal connector 10 are provided on the side wall of the box body 1. The power connector 9 is electrically connected to the power board 5, and the signal connector 10 is electrically connected to the main control board 4. In addition, an indicator light and a manually controllable button are also provided on the box body 1, which will not be described in detail here.

[0037] When in use, the wireless networking communication device is installed on the device that needs to communicate, and the signal connector 10 is connected to the corresponding device, and the power connector 9 is connected to the power supply system of the aircraft. Figure 5The Ethernet signal is transmitted to the Ethernet signal processing circuit on the main control board 4 through the signal connector 10. After being processed by the Ethernet signal processing circuit and SOC, it is converted into a USB3.0 signal. The USB3.0 signal is connected to the RF board 6 through the soft row. In the RF board 6, the USB3.0 signal is converted into a 60GHz high-frequency analog signal after encoding and decoding, high-order modulation, and up-conversion. Then it is transmitted to the array antenna, and the array antenna transmits the signal in the form of millimeter waves. The processing process of the received signal is the reverse process of the above process. Finally, the Ethernet signal is transmitted through the signal connector 10.

[0038] Different wireless networking communication devices can be networked together, and the network architecture is as follows: Figure 6 The wireless networking communication device A can establish communication connections with the wireless networking communication device B, the wireless networking communication device C, the wireless networking communication device D, the wireless networking communication device E, etc. in a one-to-many manner.

[0039] By compiling and integrating the corresponding driver in the embedded operating system kernel, it is possible to support 60GHz wireless access based on Ethernet and IEEE 802.11ad as the air interface physical layer, and the specific center frequency of access can be set by configuration (58.32GHz, 60.48GHz, 62.64GHz, 64.80GHz, one of four), and multi-point access can also be achieved through time division. The 60GHz wireless transceiver module consists of two processing modules, baseband and RF, supports IEEE802.11 ad protocol, and supports a maximum transmission rate of 4.62Gbps.

[0040] When the distance between two wireless networking communication devices is too far to effectively communicate, a third wireless networking communication device located between the two devices can be used as a relay unit to relay the signal. Figure 7 As shown, when the distance between the wireless networking communication device F and the wireless networking communication device H is far, the wireless networking communication device G located between the wireless networking communication device F and the wireless networking communication device H can receive the signal from the wireless networking communication device F and then transmit the signal to the wireless networking communication device H.

[0041] The system platform is designed based on the open source Linux system, and uses the powerful network functions of the Linux system to manage the network layer. The external high-speed channel is virtualized into a network interface to achieve communication with external IP data. The control channel is separated from the high-speed data channel using a serial port to avoid the control channel being occupied by congested high-speed data during high-speed data communication.

[0042] The platform application layer realizes docking with the external host computer, completes communication with the host computer, and forwards the data that needs to be forwarded.

[0043] The software system is designed based on the Linux open source kernel. After the device is powered on, U-boot is first read from the Flash and copied to the specified location in the memory. U-boot completes basic initialization, such as clock, uart, flash, etc. Then the Linux kernel is read from the Flash partition to the memory, and jumps to the memory to execute the Linux kernel. The Linux kernel will perform a series of verifications, register related drivers, create partitions according to the partition table, then mount the root file system, and register user processes.
