For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Embodiment

[0021] Please refer to Figure 1 , the present utility model provides a technical solution:

[0022] The present utility model provides an electronic student ID with satellite communication function, which includes a main control module 1, a satellite communication module 2, a cellular communication module 3, an antenna module 4, a satellite startup module 5, and a dual-SIM card slot module 6. The satellite communication module 2, the cellular communication module 3, the antenna module 4, the satellite startup module 5, and the dual-SIM card slot module 6 are respectively connected to the main control module 1.

[0023] In the embodiments of the present application, the electronic student ID includes a card-type electronic student ID and a wrist-type electronic student ID. The electronic student ID is provided with both a satellite communication module 2 and a cellular communication module 3. The electronic student ID defaults to using the cellular communication module 3 to connect to the mobile cellular network for daily communication and location monitoring. The main control module 1 monitors the cellular signal strength. When it detects that the cellular signal disappears or is insufficient, the main control module 1 controls the switch to the satellite communication mode, and connects to the satellite network through the satellite communication module 2 for communication and location monitoring. By setting two communication methods, the communication function of the electronic student ID is guaranteed, so that when students encounter dangerous situations, they can contact their parents or school teachers in time, and can send the students' locations in time, improving the supervision of the safety guarantee of students.

[0024] Specifically, the satellite communication module 2 includes a satellite mobile communication baseband module and a satellite communication radio frequency transceiver module.

[0025] In some embodiments of the present application, the satellite communication module 2 is the Unisoc V8821 chip, which is connected to the main control module 1 through the SPI or UARL interface. This chip supports Tiantong satellite communication and has the characteristics of high integration. It integrates core communication functions such as baseband, radio frequency, power management, and storage, ensuring low power consumption, small size, and high reliability, thus supporting the intelligent terminal to achieve continuous and stable connections in multiple vertical fields. This chip follows the 3GPP NTN R17 standard and can be easily combined with the terrestrial core network to provide diversified services including data transmission, text message delivery, calls, and location sharing through L-band maritime satellites and S-band Tiantong satellites. At the same time, it also supports access to other geostationary satellite systems to meet the communication needs of areas such as the ocean, urban fringes, and remote mountainous areas that are difficult to be covered by cellular networks.

[0026] The antenna module 4 includes a cellular communication antenna 401 and a satellite communication antenna 402.

[0027] Specifically, the satellite communication antenna 402 is a circularly polarized directional antenna, and the satellite communication antenna 402 is located at the upper part of the electronic student ID.

[0028] In the embodiments of the present application, the satellite communication antenna 402 can adopt a high-gain circularly polarized directional antenna, which can effectively improve the performance of the antenna and ensure the effectiveness of satellite communication.

[0029] Specifically, the cellular communication antenna 401 includes a main antenna and a diversity antenna, and the spacing between the main antenna and the diversity antenna is less than or equal to -15 dB.

[0030] By setting the main antenna and the diversity antenna, the main antenna can effectively enhance the signal coverage range and transmission rate, improving the stability and performance of wireless communication. The diversity antenna processes and optimizes the signal based on the main antenna, further improving the signal quality and stability, reducing signal interference and packet loss rate, and allowing users to perform wireless communication more smoothly.

[0031] The dual SIM card slot module 6 is internally provided with a cellular communication SIM card and a satellite communication SIM card, and the cellular communication SIM card and the satellite communication SIM card are respectively connected to the main control module 1.

[0032] The electronic student ID defaults to using the cellular communication SIM card. When the main control module 1 detects the disappearance or insufficiency of the cellular signal, and after the student triggers the emergency activation module, the main control module 1 will switch to connect to the satellite communication SIM card. Ensure that in different scenarios, the student ID can automatically switch the communication network according to needs.

[0033] The satellite activation module 5 includes a button activation module and a voice activation module.

[0034] The satellite startup module 5 can be used when the main control module 1 does not automatically switch to the satellite communication mode, allowing users to actively switch to the satellite communication mode, including starting by pressing a button or by setting a matching keyword for recognition.

[0035] It also includes a positioning module 7 connected to the main control module 1, which includes a GPS positioning module and a Beidou positioning module.

[0036] The positioning module 7 uploads the location information of the electronic student ID to the background in a timely manner through the satellite communication module 2 or the cellular communication module 3, enabling school administrators or parents to obtain the student's location information in a timely manner. Especially when the student is in a dangerous area such as the wilderness, the positioning information can be obtained effectively to ensure the safety of the student.

[0037] Furthermore, it also includes a power module 9, a display screen module 8, and an audio module 10 connected to the main control module 1.

[0038] The display screen module 8 provides a user interface and can be used to display the current signal status, battery level, and location information, and to prompt the operating status of the device, such as network connection status, remaining battery power, and emergency rescue startup.

[0039] The power module 9 includes a power management chip and a battery module, and the audio module 10 includes a speaker and a microphone.

[0040] The power management chip intelligently manages the power of the device, optimizes energy consumption when using cellular or satellite communication, and ensures that the device has sufficient battery life.
