With this, the demand for Internet of Vehicles equipment has increased. With the completion of the networking of Tiantong satellites and Beidou-3, infrastructure support has been provided for outdoor emergency communications. At present, there are related vehicle-mounted communication equipment on the market, but the functions are single. To meet the communication needs under different network conditions, it is necessary to purchase multiple devices, which is not cheap and extremely inconvenient. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a multifunctional vehicle-mounted fusion terminal based on the integration of Tiantong call, Beidou positioning and Beidou short message. The terminal uses Tiantong satellite and Beidou satellite to realize a network of space-ground communication, and integrates different rates and different communication methods within the coverage of ground base stations, Tiantong-1 satellites and Beidou, so as to achieve coverage of communication needs in different scenarios. The specific technical solution is as follows:

[0004] A multifunctional vehicle-mounted fusion terminal based on satellite communication includes a shell, the bottom of the shell is connected to a base plate, the side of the shell is connected to a card slot cover, the card slot cover is provided with a card slot for inserting and removing a Tiantong SIM card and a Beidou SIM card, a circuit board seat is fixed inside the shell, one side of the circuit board seat is fixed to a Beidou antenna and a Tiantong antenna, a PCB circuit board is fixed to the other side of the circuit board seat, and a main control module, a 4G full network access module, a Beidou positioning module, a Beidou short message module, a Tiantong call module, a Bluetooth module and a WIFI module are arranged on the PCB circuit board.

[0005] Furthermore, a sealing groove is provided at the connection position between the shell, the bottom plate and the slot cover for installing a sealing strip.

[0006] Furthermore, it also includes a battery pack fixed inside the shell.

[0007] Furthermore, it also includes an indicator light circuit board, which is fixed to the top of the inner part of the shell.

[0008] Furthermore, the indicator light circuit board is provided with 5 indicator lights.

[0009] Compared with the prior art, the utility model has the following significant advantages: the Beidou positioning module is adopted to ensure that the vehicle has high-precision, all-weather, and global coverage positioning capabilities, and the reliability and accuracy of the positioning service are enhanced compared to the prior art that relies only on a single GPS or other satellite navigation system. Through the built-in Tiantong satellite call module, the vehicle terminal can maintain stable voice communication even in remote areas where the communication network cannot cover, thereby improving the communication efficiency of emergency rescue and remote dispatch. The Beidou short message module provides the real-time transmission capability of text information, which is particularly critical for disaster warning in special environments. The 4G full network access module can automatically switch to the operator network with the best signal, greatly optimizing the user's Internet experience and the reliability of data transmission. The main control module uniformly manages the information interaction between each module, and transmits various data such as location information, voice calls, and short messages to the vehicle machine or mobile phone APP, so that the driver or passenger can more conveniently obtain information and control the various functions of the vehicle terminal. The Tiantong antenna and Beidou antenna use omnidirectional antennas, which greatly improve the terminal's satellite search capability and ensure that the equipment can still maintain positioning and communication functions under diverse environmental conditions, thereby improving its environmental adaptability and operational reliability.
