Description

TECHNICAL FIELD

[0002] With the wide application of unmanned aerial vehicles (UAV) in the fields of surveying and mapping, inspection, security, agricultural plant protection, emergency rescue, etc., higher requirements are put forward for the performance of the ground station system (GCS) for unmanned aerial vehicle task control and data management. As the core interaction bridge between unmanned aerial vehicles and operators, the unmanned aerial vehicle ground station is mainly used for task planning, data communication, flight monitoring, video decoding, and command issuing, etc. Its running stability, communication link quality and system integration directly affect the safety and efficiency of the unmanned aerial vehicle operation.

[0003] The existing unmanned aerial vehicle ground station system usually uses a notebook computer or an industrial tablet computer as a control terminal, which is connected to a data transmission module or a flight control device through a wired network cable to complete task planning and data transmission. Although this kind of system has a certain functional integrity, it still has the following obvious deficiencies:

[0004] (1) Limited connection mode, poor mobility.

[0005] Traditional ground stations mostly rely on Ethernet cable or USB wired connection mode, and the computer and the data transmission module must be physically connected by a network cable during use. This way not only has complex wiring and is inconvenient to carry, but also in the field operation or emergency task environment, it is easy to cause interface loosening, line winding and other problems, thereby affecting the continuity and safety of unmanned aerial vehicle control.

[0006] (2) Limited wireless coverage range.

[0007] Although some existing systems have wireless connection function, they are mostly short-distance Wi-Fi modules with limited transmission distance and susceptible to environmental interference. They cannot maintain stable signals in complex terrain (such as mountainous areas, forest land, and urban buildings), resulting in interruption of remote task planning and data transmission.

[0008] (3) Low system integration, complex equipment.

[0009] Most existing ground stations are designed independently with power module, communication module and control module, which need to be connected by multiple cables, increasing the system weight and installation complexity, and also increasing the power consumption and failure rate.

[0047] As shown in Figs. 1-3 The present application provides a WiFi ground station, which has a whole structure including a housing assembly, a control mainboard module, a wireless communication module, a power system module 3, a display and control assembly, and a heat dissipation assembly. The ground station is mainly used for realizing unmanned aerial vehicle task planning, data interaction, image transmission, and flight state monitoring, and establishing a stable signal link with the unmanned aerial vehicle through a wireless communication mode, so as to avoid the restraint problem caused by wired connection in a traditional ground station, and improve the portability and use experience of the equipment.

[0048] In the specific embodiment, the housing assembly includes a housing 1, a base 4, and a foot pad. The housing 1 is integrally formed by an aluminum alloy material, and has an installation cavity formed inside, for accommodating the control mainboard module, the power system module 3, and the wireless communication module.

[0049] The front panel, the rear panel, and the bottom of the housing 1 are fixed and packaged by screws, which can provide sufficient mechanical strength and impact resistance during transportation and field operation.

[0050] The base 4 is fixedly connected to the lower part of the housing 1, and is made of a thickened metal plate structure, for overall supporting the housing and preventing it from falling. The foot pad is arranged at the lower surface position of the base 4, and is preferably made of a silica gel anti-skid material, to increase the friction with the ground and have a certain shock absorption effect, so as to effectively inhibit the influence of vibration on the internal circuit module when the ground station is working.

[0051] The control mainboard module is installed in the main control cavity inside the shell 1, the main control module adopts a multi-layer PCB circuit board structure, and internally integrates a main processing chip, a storage chip, a signal acquisition circuit and a data bus interface.

A plurality of communication interfaces are reserved on the control mainboard module, which are used to connect the wireless communication module, the power supply system module 3 and the display and control assembly, so that stable electrical connections are formed between the modules. The module adopts an embedded operating system to realize data fusion, instruction management and task scheduling functions, and ensures real-time response under complex task conditions.

[0052] The wireless communication module is connected to the control mainboard module through a cable, and is used for signal communication of Wi-Fi or 4G / 5G network. In the present application, the wireless communication module is built-in with a high-gain antenna and a network processing chip, which can directly establish a wireless data link with the unmanned aerial vehicle without external routing equipment. In order to enhance the stability of communication, the module supports an automatic signal switching mechanism, which can automatically switch to a 4G / 5G cellular network when the Wi-Fi signal is attenuated or interrupted, so as to realize uninterrupted communication.

[0053] The wireless communication module further supports point-to-multiple communication connection, and can simultaneously establish independent data channels with multiple unmanned aerial vehicles, so as to realize multi-machine cooperative operation, partitioned inspection or formation task control.

[0054] The power supply system module 3 is arranged in the installation cavity close to the base 4 inside the shell 1, and includes a circuit board, a power module and a plug 6.

[0057] The display and control assembly is connected with the main control module through a data line, so that real-time instruction transmission and information feedback can be realized, and the operator can directly complete the flight control and task monitoring operation at the ground station end.

The assembly includes a plurality of fans and heat dissipation holes 2, and the fans are symmetrically distributed along the rear of the shell 1, forming an air flow channel with front air inlet and rear air outlet.

[0059] When the internal temperature rises to a set threshold value, the temperature control circuit automatically drives the fan to operate, and adjusts the fan speed in real time according to the temperature change, so as to maintain the stability of the internal temperature. The heat dissipation holes 2 are uniformly distributed on the rear panel and the side plate, which are used for enhancing the air convection effect, so that the main control board, the power module and the wireless module can maintain a safe working temperature in a long time operation, thereby prolonging the service life of the whole machine and improving the stability.

[0060] In order to enhance the expandability of the system, a modular expansion interface is reserved on the shell 1, which can be externally connected with image transmission modules, satellite positioning modules or AI computing modules and the like, so as to realize the multi-functional task expansion. Different functional units can be quickly installed through the expansion interface without disassembling the main machine structure, which facilitates the user to flexibly configure the system functions according to the task requirements.

[0061] The WiFi ground station of the application integrates the wireless communication module, the power system module 3, the control main board module and the display and control assembly in an integrated structure, cancels the wired connection mode relying on the network cable in the traditional ground station, and significantly improves the mobility and reliability of the system.
