[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing specific embodiments only and is not intended to limit this application.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] Although this application discloses preferred embodiments as described above, it is not intended to limit the claims. Any person skilled in the art can make several possible changes and modifications without departing from the concept of this application. Therefore, the scope of protection of this application should be determined by the scope defined in the claims of this application.

[0052] In practical implementation, the current acquisition module design is too biased towards fixed network scenarios, such as only supporting 4G communication and lacking the necessary dynamic switching capabilities. As a result, the data acquisition module of the existing technical solution cannot upload data or perform network control in scenarios where 4G signals are weak or unavailable, such as tunnels, underground garages, and remote areas. The root cause is that the existing data acquisition hardware module is only coupled to a single network interface, cannot identify and automatically switch networks, and lacks the design of backup communication paths (such as Ethernet and Wi-Fi).

[0053] Based on the aforementioned technical deficiencies, this application finds that existing data acquisition modules also suffer from poor communication protocol compatibility. The essence of the problem lies in the fact that the existing technical solutions are designed to support only a single protocol, and the protocol stack lacks universality. Consequently, existing data acquisition devices cannot adapt to different industrial equipment (such as PLCs, sensors, etc.), and lack a unified multi-protocol parsing and scheduling mechanism (such as multi-serial port DMA multiplexing).

[0054] Based on this, the present application is motivated by the need to address the aforementioned technical deficiencies of existing technologies. The present invention will now be described in further detail with reference to specific embodiments, but the embodiments of the present invention are not limited thereto.

[0055] Implementation Method 1

[0056] like Figure 1-3 As shown, in order to overcome the technical defects of the prior art, this application makes improvements to the existing data acquisition device. Specifically, the multi-network data acquisition device of this application includes a main control module 1 and a data processing module 2 and a communication module 3 electrically connected to the main control module 1; the main control module 1 is electrically connected to a USB power supply circuit, which is used to drive the main control module 1 to work; the data processing module 2 includes a data acquisition unit 21 and a data storage unit 22, the data acquisition unit 21 is used to acquire external data and output the external data to the main control module 1, and the data storage unit 22 is used to store the external data output by the main control module 1; the communication module 3 is used to transmit external data to a remote data platform, and the communication module 3 includes an Ethernet communication unit 31 and a 4G communication unit 32.

[0057] Furthermore, the working principle of the above technical solution is as follows: After the device is started, the main control module 1 begins to work, acquiring external data through the data acquisition unit 21 of the data processing module 2. The data acquisition unit 21 utilizes its built-in CAN communication chip 211 and / or 485 communication chip 212 to efficiently receive data from different industrial devices, and ensures the stability and security of data transmission through the isolation communication module 213. The acquired data is immediately output to the main control module 1 for preliminary processing and verification.

[0058] Specifically, in terms of data transmission, the communication module 3 intelligently selects either the Ethernet communication unit 31 or the 4G communication unit 32 for data transmission based on the current network environment. The Ethernet communication unit 31 connects to a local area network (LAN) or wide area network (WAN) via an RJ45 port, providing a stable and high-speed data transmission channel. The 4G communication unit 32, on the other hand, is equipped with an IoT card via a SIM card slot 321, enabling remote wireless data transmission. This flexible network connection option allows the device to adapt to data acquisition needs in different network environments.

[0059] Therefore, this application solves the technical problem that existing technical solutions cannot be matched with various communication networks, and further improves the quality of communication with local area networks, wide area networks and the Internet of Things.

[0060] Implementation Method 2

[0061] like Figure 1-4As shown, unlike Implementation Method 1, this application further enhances data security and storage capacity in existing data acquisition devices by storing data locally via a TF card, providing additional protection for data security. Even in the event of network interruption or failure, data loss is ensured, facilitating subsequent data recovery and analysis.

[0062] In the specific implementation process, the main control module 1 transmits the processed data to the data storage unit 22 of the data processing module 2 for storage. The data storage unit 22 supports both EEPROM and TF card storage media, allowing users to choose the appropriate storage method according to their actual needs. The EEPROM is connected to the main control module 1 via the IIC interface, while the TF card is connected via the TF card slot 12 on the main control module 1, ensuring the reliability and flexibility of data storage.

[0063] Furthermore, the main control module 1 is equipped with a reset unit 11, which is a watchdog timer. A watchdog timer is a commonly used hardware or software monitoring mechanism used to detect abnormal states during system operation. When a system malfunctions, such as a program crashing or freezing, the watchdog timer can trigger a reset operation, restoring the system to normal operation. In this application, the reset unit 11, acting as a watchdog timer, can effectively monitor the working status of the main control module 1, ensuring the stable operation of the data acquisition device.

[0064] Furthermore, the main control module 1 is equipped with a debugging serial port 12, which facilitates program debugging and troubleshooting, improving the maintainability of the data acquisition device. In addition, the debugging serial port 12 also supports data transmission and configuration updates, providing users with a more flexible user experience.

[0065] In terms of data transmission, communication module 3 intelligently selects either Ethernet communication unit 31 or 4G communication unit 32 for data transmission based on the current network environment. Ethernet communication unit 31 connects to a local area network (LAN) or wide area network (WAN) via an RJ45 port, providing a stable and high-speed data transmission channel. 4G communication unit 32, on the other hand, is equipped with an IoT card via SIM card slot 321, enabling remote wireless data transmission. Therefore, the technical solution of this application supports multiple communication protocols such as CAN bus and RS-485, allowing the data processing device of this application to access different types of device networks, greatly expanding its application scope and reducing the difficulty of system integration.

[0066] Furthermore, to facilitate user debugging and monitoring of the device, the main control module 1 is also equipped with a display unit 14. The display unit 14 uses multiple LEDs to visually display the device's operating status and error messages, greatly improving the device's ease of use and maintainability.

[0067] Other aspects that are the same as in Implementation Method 1 will not be described again in this implementation method.

[0068] Implementation Method 3

[0069] like Figure 1-5 As shown, unlike Embodiment 1, this application provides a portable USB power supply to further address the inconvenience caused by the need for a power connection in outdoor or mobile environments. Furthermore, when the main control module 1 is powered by an external power source, the transistor Q1 in the USB power supply circuit is disconnected, avoiding dependence on the USB interface. When the external power source is unavailable or unstable, the main control module 1 can be powered via the USB interface, at which point transistor Q1 is turned on, ensuring continuous and stable operation of the device.

[0070] Therefore, the USB portable power supply design makes the module more convenient to use in outdoor or mobile environments. This design takes into account the flexibility and portability requirements of practical applications, reducing reliance on external power sources.

[0071] Furthermore, when the USB 5V power supply is normal, transistor Q1 is turned on, and the system can switch to USB power supply mode and continue to work normally. To further illustrate the working principle of the USB power supply circuit of this application, in specific implementation... Figure 5 As shown, when the USB power supply (VBUS_5V) normally provides 5V (external power supply voltage), the voltage divider resistors (R246, R233) cause the gate potential of Q1 (Q203) to drop to about 3V, turning on the P-channel MOSFET Q1. USB power flows into the system's VCC_5V port through Q1, and the main control module 1 is powered by USB. Simultaneously, the voltage at this voltage divider point is sent to the detection port (MCU_VBUS_5V_DET) of the main control module 1 via the current-limiting resistor R238, allowing the secondary main control module 1 to identify that USB is connected. If DC_5V is present at this time, Q207 can be turned on to pull down the gate of Q2, ensuring Q2 is off and preventing DC / USB power supply conflicts.

[0072] Specifically, when the data acquisition device of this application relies solely on USB 5V power, the entire system can still achieve stable operation and power supply.

[0073] Other aspects that are the same as in Implementation Method 1 will not be described again in this implementation method.

[0074] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model. Therefore, this utility model is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed herein.
