Description

Technical Field

[0001] The utility model relates to the field of device communication transparent transmission, and more specifically, to a hub communication transparent transmission circuit and device based on Ethernet interface instant configuration and compatible with multiple devices. Background Art

[0002] With the rapid development of information technology, inter-device communication and the widespread application of the Internet of Things (IoT) have become key drivers of intelligent transformation across various industries. However, this progress is not without challenges, especially in achieving seamless interconnection and efficient management between devices, where existing technical bottlenecks and limitations are becoming increasingly prominent.

[0003] First, devices produced by different manufacturers often use unique interface standards and communication protocols. This fragmentation significantly hinders direct interconnection and data exchange between devices. For example, in a smart home system, a smart light bulb may use the Zigbee protocol, while a smart door lock may utilize Wi-Fi or Bluetooth technology. While this diversity enriches market options, it also increases the complexity and cost of system integration. Furthermore, with the continuous emergence of new protocols, such as LoRa and NB-IoT, and the widespread adoption of low-power wide-area network technologies, ensuring compatibility and a smooth transition between new and legacy devices has become a pressing issue.

[0004] Secondly, many devices are deployed in remote locations far from control centers, such as sensors in industrial sites and surveillance cameras in urban infrastructure. The decentralized nature of these devices makes traditional on-site management impractical, making remote management an inevitable choice. However, existing remote management systems often face numerous challenges, including but not limited to network latency, data security, and the accuracy and efficiency of real-time monitoring of device status. Especially when dealing with large-scale device fleets, achieving precise configuration, fault diagnosis, and performance optimization for each device has become a key factor restricting the effectiveness of remote management.

[0005] Furthermore, due to the wide variety of devices, complex protocols, and the technical difficulty of remote management, device configuration and management often become extremely cumbersome. Administrators need to master multiple technical skills to meet the needs of different devices, which not only increases labor costs but also reduces work efficiency. Furthermore, human error is inevitable during manual configuration, further exacerbating system instability and maintenance difficulties. Therefore, the development of an intelligent system that can automatically identify device types, automatically configure parameters, and enable remote unified management has become an urgent need within the industry.

[0006] In summary, existing inter-device communication and IoT technologies have significant shortcomings in terms of interface compatibility, remote management efficiency, and ease of configuration and management. These issues have severely restricted the widespread application and further development of IoT technology. Therefore, exploring and developing more efficient, flexible, and intelligent device interconnection and management technologies is of great significance for promoting the digital transformation of various industries and improving the overall operational efficiency of society.

This instant configuration capability enables the hub to quickly adapt to the access of new devices, enhancing the scalability and flexibility of the system. At the same time, a network module is equipped in the circuit. By connecting it to the master control module, the hub can be remotely configured and managed via the network. The hub and connected devices can be remotely monitored, configured, and fault diagnosed by the host computer or other remote control device, greatly improving management efficiency and reducing labor costs and maintenance difficulty. The circuit of this device also adds a CAN communication module to connect to the master control module to ensure the accuracy and stability of communication between the host computer and the hub.

[0017] By setting up a contact circuit and reserving a pad structure on the contact circuit, the hub communication transmission circuit can be configured with interfaces for connecting multiple different devices, increasing the compatibility of the device, and enabling the hub to simultaneously connect and manage multiple types of devices, effectively solving the problem of device interconnection barriers caused by different interfaces or protocols. In order to make the configured interfaces more compatible, a low-voltage bidirectional conversion circuit is also set up to connect the contact circuit and the master control module.

The normal operation of the hub communication transparent transmission circuit is ensured by regularly receiving the "feed the dog" signal (i.e. resetting or updating the watchdog timer). If the hub communication transparent transmission circuit fails or is locked, resulting in the inability to send the "feed the dog" signal in time, the watchdog module will time out and trigger the reset module to reset the system, helping the device to recover from the abnormal state or deadlock and return to the initial state, avoiding long-term stagnation or collapse of the device, and improving the reliability and stability of the device.

[0032] 2. Enable remote unified management: The introduction of the network module enables remote configuration and management of the hub over the network. Administrators can remotely monitor, configure, and troubleshoot the hub and connected devices using a host computer or other remote control device without having to be physically present on-site. This not only greatly improves management efficiency but also reduces labor costs and maintenance difficulties. Furthermore, remote management enables faster system response to device failures or anomalies, improving system stability and reliability.
