[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0022] Please refer to Figures 1-2 The embodiment of the present application provides an IoT module, which comprises a password authentication unit 11, a Wi-Fi unit 12, an NB-IoT unit 13, a communication unit 14 and a power supply unit 15 provided on a circuit board 10; the Wi-Fi unit 12, the NB-IoT unit 13 and the communication unit 14 are electrically connected to the password authentication unit 11.

[0023] In the embodiment, the password authentication unit 11, the Wi-Fi unit 12, the NB-IoT unit 13, the communication unit 14 and the power supply unit 15 are integrated on the same circuit board 10, aiming to solve several key defects that may exist in traditional IoT modules, including insufficient security, single network connection, low communication efficiency and poor energy consumption management and the like. Specifically, through the above-mentioned password authentication unit 11, effective identity verification of the device before accessing the network is ensured, preventing the access of illegal devices, thereby improving the security performance of the entire IoT system, effectively solving the problem that IoT devices are vulnerable to attacks, and enhancing the security of data transmission and storage; by integrating the Wi-Fi unit 12 and the NB-IoT unit 13, the device can not only work in a Wi-Fi environment, but also run in an NB-IoT network, which is particularly suitable for remote low-power consumption scenarios. This multi-mode network connection capability overcomes the limitations of single network connection, ensuring the connection stability of the device in different environments and the reliability of data transmission. Through the optimized design of the above-mentioned communication unit 14, the efficiency and quality of data transmission can be improved. Through efficient data processing and transmission strategies, the unit enables the device to maintain stable communication in complex network environments, reducing data delay and packet loss, which is particularly important for application scenarios with high real-time and reliability requirements. Through the power supply unit 15, power supply is provided for each unit, and through intelligent power consumption management, the unit can dynamically adjust power consumption according to the working state of the device and the network environment, reducing unnecessary energy consumption. Not only prolongs the use time of the device, but also reduces the overall operating cost, in line with the development trend of green and low carbon. It is of great significance for building a stable, secure and intelligent Internet of Things ecosystem.

[0024] As a preferred embodiment, the NB-IoT unit 13 includes a radio frequency processing module 131, and a SIM card seat 133 and a radio frequency antenna interface 132 electrically connected thereto. The above-mentioned SIM card seat 133 is used for inserting an Internet of Things SIM card, which can provide network connection with the base station similar to a mobile phone card; the radio frequency antenna interface 132 is used for receiving or sending radio frequency signals from or to the base station; the explicit division and optimized design of the above-mentioned radio frequency processing module 131, SIM card seat 133 and radio frequency antenna interface 132 ensure the stability and efficiency of NB-IoT communication. The SIM card seat 133 simplifies the network configuration process, and the radio frequency antenna interface provides a connection port for the radio frequency antenna, enhances the signal receiving and sending capability, and improves the network adaptability and data transmission quality of the module. For example, in smart water meters, smart electricity meters, remote environmental monitoring devices, etc., which are usually deployed in remote or complex environments and require stable and low-power network connection, the optimized design of the NB-IoT unit can meet these needs.

[0025] As a preferred embodiment, the power supply unit includes two LDO modules 151; the input end of the LDO module 151 is electrically connected to the power supply port provided by the circuit board 10; one of the LDO modules 151 provides power supply for the B-IoT unit 13, and the other LDO module 151 provides power supply for the Wi-Fi unit 12 and the password authentication unit 11. By using two LDO modules 151 to supply power to different units respectively, not only can the power consumption demand of each unit be finely managed to avoid power supply conflicts, but also the power consumption can be optimized to prolong the running time of the device. This design is particularly suitable for IoT devices that need to work stably for a long time. For example, in smart parking management systems, remote monitoring cameras, smart agricultural devices, etc., these devices need continuous and stable power supply, and the double-LDO design ensures that the device can maintain normal operation even in complex or unstable power supply environments.

[0026] It should be noted that LDO (Low Dropout Regulator) is a low dropout regulator, which is used to reduce the input voltage to a stable output voltage. Unlike traditional linear voltage regulators, LDO can work normally when the difference between the input voltage and the output voltage is very small. The working principle of LDO is based on linear regulation, that is, by adjusting a variable resistor (usually a transistor) to maintain a stable output voltage. Its key feature is that it can still work stably when there is a very small voltage difference (called "pressure difference") between the input voltage and the output voltage.

[0027] As a preferred embodiment, the edge position of the circuit board 10 is also provided with a TYPE-C interface; the power supply end of the TYPE-C is electrically connected to the power supply unit 15, and the data end of the TYPE-C is electrically connected to the communication unit 14. The setting of the TYPE-C interface provides a convenient power supply and data transmission mode, which can not only be used for charging the device, but also can be used as a data transmission interface, enhancing the flexibility and compatibility of the device. For example, it is applied to smart home devices (such as smart sound box, smart bulb controller), smart fitness devices, etc. These devices usually need to interact with mobile phones or PCs, and the introduction of the TYPE-C interface simplifies data transmission and device management.

[0028] As a preferred embodiment, the edge position of the circuit board 10 is also provided with a 485 plug-in interface electrically connected to the communication unit 14. The 485 interface can expand the communication capability of the device, especially in the scene where data exchange with traditional industrial devices is required. The compatibility of the 485 interface enables it to be seamlessly integrated into the existing industrial control system, wherein the 485 interface uses differential mode communication and can use two-wire system to realize long-distance communication, and has good anti-interference ability. For example, in the scene of industrial production line monitoring, large building environment control system, etc. It may be necessary to exchange data with various types of devices, and the addition of the 485 plug-in interface improves the integration and data transmission efficiency of the system.

[0029] As a preferred embodiment, the circuit board 10 is also provided with a storage queue core module electrically connected to the password authentication unit 11. The storage queue core module electrically connected to the password authentication unit 11 enhances the data processing and storage capability of the device, especially in the case of unstable network or large amount of data, which can ensure the integrity of the data and avoid data loss.

[0030] The IoT module of the present application not only optimizes the network connection, power supply management, data transmission and storage capability of the device, but also enhances the application adaptability and system integration of the device, providing a wider, more stable and safer application scene for IoT devices.

[0031] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
