Description

Technical Field

[0001] This utility model relates to the field of solid waste crushing and sorting technology, specifically to an air-space-ground satellite communication system. Background Technology

[0002] Space-air-ground satellite communication systems are core infrastructure for emergency command and field operations, enabling real-time communication and data transmission in remote areas via satellite links. Traditional systems typically use emergency command vehicles as carriers, integrating antennas, transceivers, and terminals to establish data interaction with the command center within satellite coverage. Such systems need to maintain high reliability in complex environments, especially in disaster relief and military deployment scenarios, where communication stability and deployment efficiency directly impact mission effectiveness.

[0003] For example, application number CN201320350615.8, with an authorization announcement date of 20131106, describes an air-to-ground satellite communication system. This system includes: an emergency command vehicle, an equipment cabinet, power supply equipment, an antenna, antenna control equipment, transceiver equipment, and terminal equipment. The equipment cabinet is fixed to the shell inside the emergency command vehicle's compartment; the antenna is mounted on the roof of the vehicle; the antenna control equipment includes an antenna drive device, an automatic satellite locator, and a control host; the transceiver equipment includes a satellite receiver / transmitter and a satellite modem; and the terminal equipment includes input / output devices and a processor. This air-to-ground satellite communication system enables interconnection and interoperability of comprehensive business data with a remote command center within the satellite coverage area. Through the antenna control equipment, it achieves automatic / manual satellite locating and high-precision dynamic satellite locating, thereby allowing the emergency command vehicle to maintain uninterrupted and stable communication even in harsh communication environments.

[0004] Traditional air-to-ground satellite communication systems mostly use fixed antenna structures, relying on manual operation for deployment and retrieval. This makes it difficult to meet the rapid deployment needs of emergency scenarios. Furthermore, the fixed space in the vehicle compartment results in a crowded equipment layout and a lack of dynamic expansion capabilities. Therefore, there is an urgent need to design an air-to-ground satellite communication system to solve these problems. Utility Model Content

[0048] Signal Conversion and Relay Network Module 13:

[0049] The communication antenna 25 receives satellite signals and transmits them to the signal conversion and relay network module 13;

[0050] The signal conversion and relay network module 13 performs 4G / 5G / satellite signal demodulation and relay, and outputs the signal to the central control console 14 for display.

[0052] Working Principle: When the system needs to enter the working state, the intelligent control and energy management module 12 issues a command to start the winding motor 22. The winding motor 22 rotates in the forward direction, driving the two winding wheels 21 through the coupling to synchronously release the traction rope 27. One end of the traction rope 27 is fixed to the fixing block 26 on the top of the blade 24. As the traction rope 27 is released, the two blades 24, which were originally gathered in the mounting area 19 at the bottom of the frame 18, begin to rotate outward around the bearing axis connected to the mounting groove 6 under the action of gravity. The traction rope 27 passes around the roller 23, which plays a guiding role and reduces friction, ensuring a smooth traction process. When the blade 24 rotates to a horizontal position or a predetermined angle, the winding motor 22 stops working. At this time, the communication antenna 25 installed at the bottom of the blade 24 is fully exposed outside the carriage 2, in the optimal signal receiving and transmitting position, and can begin to automatically seek satellites and establish a link with satellites. The retraction process is the reverse, with the winding motor 22 reversing to gather the traction rope. 27. Pull the blade 24 back to the vertically retracted state; if space expansion is needed simultaneously or after the antenna is deployed, the box cover 8 can be opened first, and then the intelligent control and energy management module 12 can be used to control the hydraulic system of the command vehicle 1 to supply oil to the telescopic hydraulic cylinder 10. The piston rod of the telescopic hydraulic cylinder 10 extends, pushing the pad 17 at its output end to move outward in the I-shaped groove 9. The pad 17 will contact the ground and support the deployed box cover 8. As the box cover 8 is deployed, the second slide groove 16 on it is completely connected with the first slide groove 7 on the floor of the carriage 2, forming a continuous slide rail; the operator can manually or through the auxiliary motor drive the sliding plate 11. The sliding plate 11 is an integrated functional unit, on which a seat 15, a center console 14, an intelligent control and energy management module 12, and a signal conversion and relay network module 13 are mounted. Its removal means that a complete workstation is moved from the crowded carriage 2 to the spacious extended space. The telescopic hydraulic cylinder 10 can be finely adjusted according to the flatness of the ground. The cover plate 8 is supported and leveled by the pad 17 to ensure the stability of the extended space and provide a stable foundation for the operation of the equipment on the sliding plate 11. The communication antenna 25 captures... The satellite signal is transmitted to the signal conversion and relay network module 13. This module performs modulation, demodulation, encoding and decoding of the signal. The processed signal can be distributed to the terminal equipment on the central control console 14 via wired or wireless means, or a local network can be built through the relay function for multiple users to access. The intelligent control and energy management module 12 provides power to the winding motor 22, communication antenna 25, and other modules and manages energy distribution. On the other hand, it receives feedback signals from all devices and can automatically or according to instructions control the opening and closing of the intelligent roller shutter door 3, the start and stop of the winding motor 22, the power amplifier of the communication antenna 25, etc., to achieve intelligent centralized control.
