Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a quadruped robot for emergency satellite communication in a space-ground collaborative manner. Background Technology

[0002] Quadruped robots are mobile robots with high adaptability and stability to complex terrain. They can replace humans in complex environments for guarding or transporting supplies. Conventional quadruped robots rely on two types of wireless remote control: local area network (LAN) remote control (such as local mobile phone, handheld remote control, etc.) or terrestrial cellular network wireless remote control. In emergency environments where the quality of terrestrial cellular network radio signals is poor, communication and remote control cannot be carried out. Especially in emergency scenarios such as earthquakes, floods, fires, and mudslides, where rescuers cannot reach, there is an urgent need to understand the actual situation on the ground in real time, but there are objective difficulties such as life safety hazards and the need to restore on-site emergency communication, which bring great challenges and safety hazards to emergency rescue work. Utility Model Content

[0003] The purpose of this invention is to provide a space-ground collaborative emergency satellite communication quadruped robot to solve the problem that existing quadruped robots cannot communicate and be remotely controlled in emergency environments where the quality of ground cellular network radio signals is poor.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A space-ground collaborative emergency satellite communication quadruped robot includes: a quadruped robot carrier and a space-ground collaborative satellite communication terminal;

The modem unit is connected to the broadband satellite phased array transceiver unit.

[0008] Furthermore, the aforementioned broadband satellite phased array transceiver unit includes a frequency conversion component, an antenna subarray, and a low-noise amplifier.

[0009] Furthermore, the aforementioned antenna subarray adopts a 1024 phased array subarray.

[0010] Furthermore, the aforementioned space-ground integrated satellite communication terminal also includes a GNSS receiving unit and an ACU satellite locator unit, with the ACU satellite locator unit connected to the routing and switching unit and the GNSS receiving unit, respectively.

[0011] Furthermore, the above also includes a replaceable adapter, which includes a control drive unit, an alarm light unit, a horn unit, and a pickup unit. The control drive unit is connected to the alarm light unit, the horn unit, the pickup unit, and the ACU satellite search unit, respectively.

[0014] This utility model has the following beneficial effects:

[0015] (1) In emergency rescue environments where rescuers have difficulty reaching the site and the quality of radio signals from ground cellular networks is poor, using broadband satellite communication networks to replace ground cellular network communication can reduce the dependence of emergency rescue sites on the construction of ground cellular networks. Using broadband satellite communication networks to remotely control quadruped robots to reach emergency rescue sites or sites with safety hazards can reduce the safety risks for rescuers.

[0016] (2) The space-ground collaborative emergency satellite communication quadruped robot of this utility model can collect on-site data such as audio and video, and terrain, and transmit them to the back-end center through a broadband satellite communication network to remotely grasp the on-site information of emergency rescue in real time.

[0017] (3) The quadruped robot for emergency satellite communication in the space-ground collaboration of this utility model can convert broadband satellite communication into local self-organizing network radio signals (such as 4 / 5G micro base stations, WiFi) to provide satellite Internet access services to other nearby communication terminals.

[0018] Figure 1 This is a schematic diagram of the four-legged robot for emergency satellite communication in conjunction with the space-ground system, which is based on this utility model. Detailed Implementation

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] Please refer to Figure 1 This embodiment provides a space-ground collaborative emergency satellite communication quadruped robot, comprising:

[0021] Quadruped robot vehicles, as physical vehicles and carriers of the perception layer, mainly provide surrounding terrain perception and edge computing modeling, and move and operate in complex environments according to input instructions;

[0022] The space-ground collaborative satellite communication terminal is used to demodulate the received satellite communication signals, providing Internet access to users within the local area network coverage area near the quadruped robot, and can also achieve signal coverage similar to cellular networks.

[0023] It also includes replaceable adapters, which can meet various needs in different emergency rescue scenarios, such as on-site emergency alarm intercom devices with sound and light, infrared camera devices for emergency search and rescue and fire temperature sensing, and emergency transport compartment devices (such as emergency medical kits, emergency food, etc.).

[0024] In this embodiment, the quadruped robot carrier includes a power supply unit, a battery unit, a wired transmission unit, an attitude control unit, an optical camera unit, a depth camera unit, a lidar unit, a system-on-a-chip (SoC), a hip joint drive module unit, a thigh joint drive module unit, a lower leg joint drive module unit, and a wheel-foot drive module unit. The power supply unit and the battery unit are connected to provide electrical power. The wired transmission unit, attitude control unit, optical camera unit, depth camera unit, lidar unit, hip joint drive module unit, thigh joint drive module unit, lower leg joint drive module unit, and wheel-foot drive module unit are all connected to the SoC.

[0025] In this embodiment, the space-ground collaborative satellite communication terminal includes a wireless local area network (WLAN) transceiver unit, a terrestrial cellular network (TDN) transceiver unit, a micro base station transceiver unit, a routing and switching unit, a broadband satellite phased array transceiver unit, and a modem unit. The routing and switching unit is connected to the wired transmission unit, the WLAN transceiver unit, the TDN transceiver unit, the micro base station transceiver unit, and the modem unit, respectively. The modem unit is connected to the broadband satellite phased array transceiver unit.

[0026] The broadband satellite phased array transceiver unit includes a frequency conversion component, an antenna subarray, and a low-noise amplifier. The antenna subarray, serving as the transceiver component of the satellite communication terminal, is preferably a 1024 phased array subarray.

[0027] The broadband satellite phased array transceiver unit receives satellite communication signals and transmits them to the modulation and demodulation unit after down-conversion, low-noise amplification, filtering, analog-to-digital conversion, and interference suppression. The demodulation unit then transmits the demodulated signal to the routing and switching unit, which then sends it to the wireless LAN transceiver unit and / or the micro base station transceiver unit. The wireless LAN transceiver unit provides internet access to users within the LAN coverage area near the quadruped robot. Considering the limited coverage of the wireless LAN, micro base stations can also be used to achieve signal coverage similar to a cellular network, resulting in a wider coverage area.

[0028] The space-ground integrated satellite communication terminal also includes a GNSS receiving unit and an ACU (Air-to-Center) satellite locator unit. The ACU satellite locator unit is connected to both the routing and switching unit and the GNSS receiving unit. The GNSS receiving unit is used to achieve global positioning for the space-ground integrated satellite communication terminal, and uses positioning data and ephemeris data from high and low Earth orbit satellites to enable the ACU satellite locator unit to locate and track satellites. The ACU satellite locator unit can achieve beam tracking through electronic scanning, maximizing satellite signal quality.

[0029] In this embodiment, the space-ground collaborative satellite communication terminal also includes a temperature control unit.

[0030] The replaceable adapter includes a control drive unit, an alarm light unit, a horn unit, and a pickup unit. The control drive unit is connected to the alarm light unit, the horn unit, the pickup unit, and the ACU satellite locator unit. The ACU satellite locator unit calculates the adjustment amounts for azimuth, elevation, and polarization angles based on positioning data and ephemeris data from high and low orbit satellites. These adjustments are then transmitted to the control drive unit, which controls the azimuth, elevation, and polarization components to achieve precise satellite alignment.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
