[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] like Figure 2 and 3 As shown, an Internet of Things gateway based on the LORA protocol described in an embodiment of the utility model includes a control mainboard 1, on which is provided a main control module 2 for controlling the operation of the Internet of Things gateway, and a first storage module 301, a second storage module 302, and a communication module 4 connected to the main control module 2, the communication module 4 being used to download a first operating system or a second operating system, the first storage module 301 being used to store the first operating system, the second storage module 302 being used to store the second operating system, and the main control module 2 running the first operating system or the second operating system.

[0045] When the Internet of Things gateway is deployed for the first time, the first storage module 301 has a built-in first operating system, and the main control module 2 loads the first operating system and runs it. A connection is established with a remote server through the communication module 4 to obtain the latest system update information. When there is a new system update, the communication module 4 will download and store the second operating system in the second storage module 302. At this time, the main control module 2 continues to stably operate the first operating system to ensure that the normal operation of the Internet of Things gateway is not affected. During the system maintenance window, the main control module 2 will try to switch to the second operating system in the second storage module 302. If the second operating system can run stably, the Internet of Things gateway will continue to use the system until the next system update. However, if the second operating system is found to be unstable or unable to run during the switching process, the main control module 2 will immediately switch back to the first operating system to ensure the continuity and stability of the Internet of Things gateway.

[0046] The Internet of Things gateway in this embodiment achieves seamless switching and system backtracking of system updates by introducing dual storage modules and switching mechanisms, which ensures the security and reliability of system updates while ensuring the continuous and stable operation of the Internet of Things gateway. When there is a new system update, the Internet of Things gateway can perform system upgrades without interrupting services, improving the maintainability and flexibility of the system. At the same time, even if the new system has unknown vulnerabilities or defects that make it unable to run stably, the Internet of Things gateway can quickly switch back to the old system, avoiding service interruptions and data loss caused by system updates, which not only improves the reliability of the Internet of Things gateway, but also reduces the cost and risk of system maintenance. In addition, through timely system updates and backtracking mechanisms, the Internet of Things gateway can better adapt to complex and changing application environments and provide users with more stable and reliable Internet of Things services.

[0047] Specifically, it is designed based on the ARM architecture and uses a quad-core Cortex-A55 CPU with a frequency of 1.8GHz.

[0048] The quad-core Cortex-A55 CPU design based on the ARM architecture has efficient task allocation and parallel processing capabilities. The ARM architecture has a streamlined instruction set and excellent performance-to-power ratio, and the Cortex-A55 CPU is deeply optimized for low-power applications. The quad-core design allows the CPU to process four independent tasks or threads at the same time, improving the overall processing power. The frequency is as high as 1.8GHz, ensuring fast response and data processing even under high load conditions. In addition, the Cortex-A55 also has a dynamic frequency adjustment function, which can adjust the core frequency according to the actual load conditions, thereby reducing power consumption while ensuring performance.

[0049] In terms of performance, the quad-core parallel processing capability of this embodiment enables the device to easily cope with multi-tasking scenarios, whether it is complex computing tasks or high-load applications, they can be processed smoothly and efficiently. Secondly, in terms of power consumption, the low-power design and dynamic frequency adjustment function of Cortex-A55 enable the device to achieve low energy consumption while maintaining high performance.

[0050] like Fig.21 As shown, in a preferred embodiment, the control mainboard 1 is provided with a security module 5 connected to the main control module 2, and the security module 5 is used for identity authentication or data encryption. The security module 5 includes an encryption chip ECC608.

[0051] During the working process, the control motherboard 1 first burns a unique SN code before the device leaves the factory. As the SN code is burned, the login passwords for the serial console and SSH are also generated based on the SN code through an encryption algorithm (such as CRC cyclic redundancy check) to ensure that each device has a unique login credential and achieves one machine and one password. Subsequently, when the device is started for the first time, the user needs to use a specific gateway_mfr command to generate a gateway key and fix the key to the onboard ECC608 encryption IC through the gateway_mfr command. Once the ECC608 configuration is locked, the key will be irreversibly stored and can only be read through an authorized command. When the device is running, the application will periodically read the product key and compare it with the key stored in the ECC608. If the key is consistent, it will run normally, otherwise the application will fail to run, thereby ensuring the security of key applications or information in the system.

[0052] In this embodiment, by setting up the security module 5, the SN code is burned and the password is generated before the device leaves the factory, so as to realize the identity authentication and data transmission encryption between devices, and effectively prevent unauthorized access and data leakage. Secondly, the introduction of the onboard ECC608 encryption IC and the irreversible solidification of the key further enhance the security performance of the system, making any unauthorized modification or tampering extremely difficult. In addition, the regular comparison mechanism of the key during application runtime ensures the continuous security protection of the key applications or information of the system, enhances the security of the IoT ecosystem, and improves the user's trust in the security of the system.

[0053] like Figure 11-Figure 17 As shown, in a preferred embodiment, a power supply module 6 for supplying power is provided on the control main board 1. The power supply module 6 includes a PMIC circuit and a power input circuit.

[0054] During operation, the power supply module 6 first receives the DC 12V external power input through the power input circuit. Subsequently, the power is processed and converted to meet the voltage requirements of different functional modules inside the product. The PMIC circuit configures different voltage values ​​according to the current working state of the device and the requirements of each functional module, and turns on and off the voltages of different functional modules through the control switch. At the same time, in order to ensure the reliability and stability of the product, it is equipped with an overvoltage and overcurrent automatic mechanism. When the power input exceeds the preset safety range, the mechanism will automatically trigger, cut off the power input or adjust the voltage value to prevent damage to the device.

[0055] In this embodiment, through the intelligent power management of the PMIC circuit, the power efficiency of the device is greatly improved, and different functional modules can obtain stable voltage supply according to actual needs, thereby ensuring the normal operation and performance of the device. Secondly, the introduction of the overvoltage and overcurrent automatic mechanism greatly enhances the safety performance of the product. When the power input is abnormal, it can respond quickly to protect the device from damage, thereby improving the reliability and stability of the product.

[0056] like Fig. 20 As shown, in a preferred embodiment, a clock power supply module 7 is provided on the control main board 1 .

[0057] During operation, when the device is powered normally, the clock power supply module 7 (RTC circuit) is synchronized with the system power supply to provide a stable time base signal for the device's clock. At the same time, the RTC circuit is also equipped with an independent backup power supply (such as a small battery). When the system main power supply is cut off, the backup power supply will immediately take over and provide a continuous and stable power supply for the RTC circuit. In the case of a system power outage, the RTC circuit can continue to work to ensure that the device's clock keeps accurate time.

[0058] In this embodiment, by setting up a clock power supply module, the device can still maintain accurate clock time in a power-off state, which is crucial for application scenarios that require time continuity (such as security monitoring, financial transactions, etc.). Secondly, the independent backup power supply design of the RTC circuit ensures the reliability of the clock function when the system main power fails, and improves the overall stability and reliability of the device.

[0059] like Figure 3 As shown, in a preferred embodiment, the communication module 4 includes a wired communication unit 401 and a wireless communication unit 402 .

[0060] The wired communication unit 401 is connected through a physical cable to realize data transmission between devices or between a device and a server. It usually has the characteristics of high speed, stability, and strong anti-interference ability, and is suitable for scenarios with high requirements for data transmission speed and stability. The wireless communication unit 402 uses wireless signals for data transmission without physical connection, and has the advantages of flexibility, convenience, and wide application range. In the Internet of Things gateway, the wireless communication unit 402 usually supports multiple wireless protocols, such as Wi-Fi, Bluetooth, ZigBee, etc., to meet the needs of different application scenarios. During the working process, the wired communication unit 401 and the wireless communication unit 402 work together, select the appropriate communication method according to actual needs, and ensure reliable data transmission. In addition, through the collaborative work of wired and wireless communications, data backup and redundant transmission can be achieved, further improving the reliability and stability of the system.

[0061] like Fig. 9 As shown, in a preferred embodiment, the wired communication unit 401 includes an Ethernet communication component and a USB communication component. The Ethernet communication component includes an RTL8211F circuit and a LAN port, and the USB communication component includes a USB interface circuit, and the USB interface circuit includes two USB interfaces, namely a USB OTG interface and a USB2.0 Host interface. The OTG interface is used for local firmware downloading; the Host interface is used for USB data transmission.

[0062] During operation, the Ethernet communication component is connected to the external network through the LAN port (local area network interface), and the Gigabit network card RTL8211F circuit is used to ensure the high speed and stability of data transmission. When the Lora module collects local data from the short-range LAN, the data is processed and processed by the CPU of the control motherboard 1. After the processing is completed, the data will communicate with the external Internet through the Gigabit network card RTL8211F circuit to realize the function of remote monitoring of each Lora node. At the same time, the USB interface circuit provides two USB interfaces, one of which is a USB OTG interface for local firmware download, making the firmware update of the device convenient and fast; the other is a USB2.0 Host interface for USB data transmission, supporting data exchange between the device and other USB devices.

[0063] In this embodiment, by setting up Ethernet communication components, the data transmission speed and stability are improved, the efficiency and reliability of the communication between the system and the Internet are improved, and the function of remote monitoring of each Lora node is realized. In addition, the design of two USB interfaces provides a convenient way to download firmware locally and transmit USB data, expands the connectivity and functionality of the device, and enhances the versatility and scalability of the device, which not only meets the communication and data transmission needs of IoT devices, but also improves the ease of use and user experience of the device.

[0064] like Figure 6-Figure 8 As shown, in a preferred embodiment, the wireless communication unit 402 includes a mobile communication component, a wireless network communication component, a Bluetooth communication component and a Lora communication component. The mobile communication component includes a Mini-PCIe 4G module and a SIM card slot. The wireless network communication component and the Bluetooth communication component are integrated in a WIFI & BT two-in-one module.

[0065] The Mini-PCIe 4G module can realize the 4G network Internet access function by inserting a SIM card, so that the device can exchange information anytime and anywhere. Secondly, the WIFI&BT two-in-one module not only supports WIFI wireless Internet access, but also has Bluetooth function. Users can communicate with the system at close range through mobile phone APP or applet to control the device or obtain information. In this process, the user can operate easily and complete the configuration and connection of the gateway through a smart mobile terminal (such as a mobile phone, tablet computer, etc.). In addition, the short-distance communication Lora module communicates locally with other local devices equipped with Lora, and exchanges information with the CPU system through the SPI protocol to ensure that the CPU system can interact with these devices in real time.

[0066] In this embodiment, by integrating multiple wireless communication technologies, the wireless communication unit 402 provides users with a variety of communication methods to meet the communication needs in different scenarios. The application of Mini-PCIe 4G module and WIFI&BT two-in-one module enables the device to exchange information and transmit data anytime and anywhere, improving the convenience and efficiency of communication. The short-distance communication Lora module ensures real-time interaction between local devices, making the entire system more intelligent and efficient. In addition, users can complete the configuration and connection of the gateway through a smart mobile terminal, which greatly simplifies the operation process and improves the user experience.

[0067] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the memory module 3 includes an LPDDR4 / 4X circuit, and the LPDDR4 / 4X is provided with two partitions, CH A and CH B, namely, a first storage module 301 and a second storage module 302, respectively.

[0068] During operation, the two partitions CH A and CH B operate independently and can work together to meet the needs of high-speed data processing. When data needs to be read or written, the system will assign the task to CH A or CH B according to the needs. For example, when one partition is busy processing data, the other partition can receive new data requests, thereby achieving parallel processing and improving overall processing efficiency.

[0069] In this embodiment, since the two partitions operate independently, when one partition fails, the other partition can continue to work, which enhances the fault tolerance and stability of the system. Through parallel processing, the system can process multiple data requests at the same time, thereby reducing waiting time and improving overall performance. Secondly, it can more effectively utilize bandwidth, reduce data congestion, and make data transmission smoother.

[0070] like Fig.18 and Fig.19 As shown, in a preferred embodiment, a flash memory module 12 connected to the main control module 2 is provided on the control main board 1. The flash memory module 12 includes an EMMC circuit for storing device system and user data.

[0071] In a preferred embodiment, the control mainboard 1 is provided with a memory expansion interface 8, which is used to connect a memory card. The memory expansion interface 8 is such as a TF card interface, with a built-in Micro SD card. It is used for users who need to expand the second data storage; the Micro SD card supports hot swapping.

[0072] When the user needs to increase the storage space, he can prepare a Micro SD card of appropriate capacity and insert it into the TF card interface on the motherboard. The main control module 2 of the motherboard recognizes and initializes the memory card and incorporates it into the system's storage management. After that, both the data generated by the device system and the files stored by the user can be selectively written to this Micro SD card, thereby realizing the expansion of data storage. Since the Micro SD card supports hot plugging, the user can plug and unplug it at any time during the operation of the device without worrying about data loss or system crashes.

[0073] In this embodiment, by providing the memory expansion interface 8, it is convenient for users to expand the storage capacity of the device to meet the needs of data storage in different application scenarios. Secondly, the high capacity and low cost characteristics of the Micro SD card make this expansion method economical and practical. Furthermore, since hot plugging is supported, users can replace or remove the memory card without shutting down the device, which greatly improves the convenience and flexibility of operation.

[0074] In a preferred embodiment, a power indicator light and a system indicator light are provided on the control main board 1 to display the operating status of the Internet of Things gateway.

[0075] In a preferred embodiment, a display module 9 is disposed on the control main board 1 , and the display module 9 is connected to a display screen.

[0076] On the control mainboard 1, the display module 9 is connected to the display screen through the HDMI interface to realize the output of system-related information. When the user needs to use the display screen to view system information or perform other visual interactions, the display module 9 on the mainboard receives instructions from the main control module 2 and sends corresponding display signals. The signals are transmitted to the display screen through the HDMI interface. The display screen decodes and renders according to the received signals, and finally presents the system interface or information content required by the user.

[0077] In this embodiment, the high bandwidth characteristic of the HDMI interface ensures the quality of the transmitted display signal, allowing users to enjoy clear and delicate picture quality. Secondly, the popularity and compatibility of the HDMI interface allow users to easily connect display screens of various types and brands, improving the versatility and scalability of the device. In addition, the low latency characteristic of the HDMI interface ensures the real-time transmission of the display signal, avoiding the degradation of the visual experience caused by latency. Finally, by outputting system-related information through the HDMI interface, users can intuitively understand the operating status and parameter settings of the device, which provides convenience for the debugging and maintenance of the device.

[0078] like Figure 1 As shown, in a preferred embodiment, the control mainboard 1 is provided with a plurality of antenna interfaces 10, and the antenna interfaces 10 are used to connect the LORA antenna. An external antenna is used to expand the network coverage; wherein the LORA antenna has a gain of 4dBi, and is provided with an extension cable and a strong magnetic suction cup for easy installation.

[0079] Users can choose to connect antennas with different frequency bands and gains according to their needs to optimize network coverage and signal quality. Among them, the LORA antenna gain is 4dBi. When the device needs to expand the network coverage, the user can connect the LORA antenna to the antenna interface 10 on the motherboard through an extension cable and fix it in place with a strong magnetic suction cup. After the connection is completed, the LORA antenna starts to receive and send signals.

[0080] In this embodiment, by adopting external antenna technology, the gain of 4dBi makes the LORA antenna have stronger penetration and longer transmission distance when receiving and sending signals, thereby effectively expanding the network coverage. Secondly, the extension line and strong magnetic suction cup provide users with a flexible installation method, and they can choose a suitable location for fixing according to actual needs, further improving the stability and reliability of the network signal.

[0081] like Fig.10 As shown, in a preferred embodiment, a control button 11 is provided on the mainboard, including two buttons, a Bluetooth pairing button and a system button. The system button is used for resetting the product or upgrading the product firmware.

[0082] When a connection needs to be established with other Bluetooth devices, the user presses the Bluetooth pairing button, and the device enters the Bluetooth pairing mode. The device starts searching for surrounding Bluetooth devices and prepares to establish a connection. When the user needs to restart the device, the system button is short pressed, and when the device firmware is updated, the system button is long pressed. The control button 11 provides the user with more operation options, making the use of the device more flexible and convenient.

[0083] In a preferred embodiment, an aluminum alloy shell 13 is disposed on the outer side of the control main board 1 .

[0084] During the production process, a solid and dense oxide layer is formed on the surface of the aluminum alloy shell 13 outside the control mainboard 1. Under normal circumstances, the oxide layer can effectively isolate corrosive substances in the external environment, such as moisture, oxygen, acid and alkali, thereby preventing direct contact with the aluminum alloy shell 13 and chemical reactions. During the use of the equipment, the aluminum alloy shell 13 can maintain the integrity and stability of the structure by exerting its excellent corrosion resistance, regardless of the humidity, dust or other harsh environments, ensuring that the internal control mainboard 1 and electronic components are well protected, so that the equipment can operate stably in various complex environments, and reduce equipment damage and failure rate caused by corrosion.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
