[0058] In another alternative embodiment, as Figure 3 shown, the main control module 10 includes a main control chip 11, a reset circuit 12, an external crystal oscillator 13, an indicator light 14, and a programming interface 15, where:

[0059] The first end of the main control chip 11 is electrically connected to the quantum encryption and decryption module 20, the second end of the main control chip 11 is electrically connected to the first end of the downlink data interface 30, and the third end of the main control chip 11 is electrically connected to the first end of the wireless transmission interface 40;

[0060] The reset circuit 12 is electrically connected to the fourth end of the main control chip 11; the external crystal oscillator 13 is electrically connected to the fifth end of the main control chip 11; the indicator light 14 is electrically connected to the sixth end of the main control chip 11; the programming interface 15 is electrically connected to the seventh end of the main control chip 11.

[0061] In this alternative embodiment, as Figure 4As shown, the main control module 10 includes a main control chip 11, a reset circuit 12, an external crystal oscillator 13, an indicator light 14, and a programming interface 15. Among them, all the electronic components included in the main control module 10 and the connection relationships between all the electronic components can be as Figure 4 shown, and the main frequency of the main control chip 11 can be 144 MHz, and a RISC-V core can be adopted.

[0062] In this optional embodiment, the main control module 10 is the core part of the electronic device and is responsible for the operation and control of the entire system. Among them, the main control chip 11 is the core part of the main control module 10, responsible for processing various data and instructions and controlling the work of other modules. Its first end is electrically connected to the quantum encryption and decryption module 20 for data encryption and decryption; its second end is electrically connected to the first end of the downlink data interface 30 for data transmission with external devices; its third end is electrically connected to the wireless transmission interface 40 for wireless data transmission.

The data protection circuit 32 can include several TVS diodes for absorbing electrical surges.

[0068] In the design of embedded systems and communication devices, the communication chip 31 and the data protection circuit 32 play a crucial role. The communication chip 31 is responsible for handling data transmission with external devices, while the data protection circuit 32 protects these data lines from overvoltage or electrical surges, ensuring the reliability and stability of the system.

[0069] The communication chip 31 is usually responsible for performing data signal conversion and transmission tasks. For example, the MAX232 chip can convert the RS232 signal level from -10V to +10V of a computer serial port into the TTL signal level from 0V to +5V used by a microcontroller. This conversion is necessary for communication between a computer and a microcontroller.

[0070] The data protection circuit 32 is an important line of defense to prevent sudden electrical surges or overvoltages from damaging sensitive electronic devices. Such circuits usually include transient voltage suppression TVS diodes, which are designed to absorb high-energy electrical surges and keep them at a safe level. For example, in the RS232 interface protection circuit, since the RS232 port is often hot-plugged and is vulnerable to overvoltage and overcurrent impacts, adding bidirectional transient suppression diodes BS0150MS and appropriate current-limiting resistors can effectively protect and reduce the risk of damage to the interface chip.

[0071] In another alternative embodiment, the data protection circuit 32 includes a first TVS diode, a second TVS diode, and a third TVS diode, where:

[0072] As Figure 5 shown, all the electronic components included in the data protection circuit 32 and the connection relationships between all the electronic components can be as Figure 5 shown, where the anode of the first TVS diode D5 is used for grounding, the cathode of the first TVS diode D5 is electrically connected to the anode of the second TVS diode D6, the cathode of the second TVS diode D6 is electrically connected to the cathode of the third TVS diode D7, and the anode of the third TVS diode D7 is used for grounding;

[0073] And, a first node B1 is provided between the cathode of the first TVS diode D5 and the anode of the second TVS diode D6, a second node A1 is provided between the cathode of the second TVS diode D6 and the cathode of the third TVS diode D7.

Thus, the communication chip 31 is protected by the data protection circuit 32 from overvoltage or electrical surges, ensuring the reliability and stability of the entire circuit.

It can be seen that in this alternative embodiment, the combined use of the CAT1 module 41 and the SIM card module 42 provides a reliable wireless connection method for the wireless data transmission unit circuit. This combination not only ensures the network connection and data transmission capabilities of the wireless data transmission unit circuit, but also enhances the performance and low-power characteristics of the device in a mobile environment.

[0079] In this alternative embodiment, the IIC interface 16 only requires two signal lines, namely the data line SDA and the clock line SCL, which greatly simplifies the circuit design, reduces the space of the circuit board and the number of chip pins, and reduces the interconnection cost. The UART interface 17 is a widely used serial communication protocol, which has a simple structure, is easy to implement, and has low development and debugging difficulty.
