[0052] Please see Figure 1 , Figure 1 The circuit block diagram of the edge computing system based on micro-dynamic ring (hereinafter referred to as "edge computing system") provided in this application is shown. The edge computing system 100 includes a micro-dynamic ring capability baseboard 110, a function expansion board 120, a high-performance CPU board 130, a power module board 140, a data network board 150, a neural network computing board 160, a cryptographic algorithm board 170, a streaming media encoding / decoding board 180, and an Internet of Things hardware interface expansion board 190. Taking the circuit connection method of the edge computing system 100 as an example, the function expansion board 120 is electrically connected to the micro-loop capability baseboard 110, the high-performance CPU board 130 is electrically connected to the micro-loop capability baseboard 110, the power module board 140 is electrically connected to the micro-loop capability baseboard 110, the data network board 150 is electrically connected to the micro-loop capability baseboard 110, the neural network computing board 160 is electrically connected to the micro-loop capability baseboard 110, the cryptographic algorithm board 170 is electrically connected to the micro-loop capability baseboard 110, the streaming media encoding and decoding board 180 is electrically connected to the micro-loop capability baseboard 110, and the IoT hardware interface expansion board 190 is electrically connected to the micro-loop capability baseboard 110.

[0053] In one embodiment, the micro-circuit capability baseboard 110 includes a low-performance CPU, a local database, and multiple PCIe slots. For example, the micro-circuit capability baseboard 110 has 10-20 PCIe (Peripheral Component Interconnect Express, a high-speed serial computer expansion bus standard used to replace older PCI, PCI-X, and AGP bus standards. PCIe is a high-speed serial point-to-point dual-channel high-bandwidth transmission, where connected devices are allocated dedicated channel bandwidth and do not share bus bandwidth. It mainly supports active power management, error reporting, end-to-end reliable transmission, hot-swapping, and quality of service functions.) PCIe slots are used to provide power and data communication functions between corresponding boards. "Corresponding boards" can refer to all boards in the edge computing system 100 except for the micro-circuit capability baseboard 110. Therefore, PCIe slots can provide power to all corresponding boards and also provide data communication functions between corresponding boards in information transmission. For example, the PCIe slot connected to the onboard power module (not shown) of the micro-circuit capability baseboard 110 can provide power to other inserted boards. The micro-circuit capability baseboard 110 also provides 4G wireless communication and internet access functions, as well as baseboard data communication and exchange functions. Specifically, the micro-circuit capability baseboard 110 connects to external terminals via a 4G module through the 4G wireless communication and internet access function, and provides an operation and maintenance API interface. The low-computing-power CPU integrates the enable and disable signals of basic smart pole services (such as switch control of lighting, temperature and humidity detection, and smart pole tilt monitoring) through a local database, effectively increasing functionality and applicability.

[0054] In one embodiment, when the micro-loop capability baseboard 110 detects an inserted card in the function expansion board 120 via an IO interrupt, it performs handshake authentication and heartbeat timing detection with the inserted card. For example, the inserted card may be an asynchronous large-screen display board, a one-button emergency call board, or an IP broadcast board. The asynchronous large-screen display board provides media program playback functionality, which can be used for data processing between the LED device management platform and the LED playback device. The one-button emergency call board provides a one-button alarm state function; pressing the button enters the alarm state. The function expansion board 120 can exchange data with the inserted card via an API interface. When the micro-loop capability baseboard 110 performs handshake authentication and heartbeat timing detection with the inserted card, if the handshake authentication is complete, a secure TCP channel is established and activated. The heartbeat timing detection then determines whether a time threshold has been exceeded. If the time threshold has not been exceeded, a secure channel is established; if the time threshold has been exceeded, the handshake authentication is re-performed. The micro-loop capability baseboard 110 controls the power-on and power-off of the inserted card through power IO states based on enable and disable signals. Furthermore, the micro-circuit capability base plate 110 controls the power-on of the inserted board through the power IO state based on the enable signal, and controls the power-off of the inserted board through the power IO state based on the de-enable signal, thereby increasing the degree of electronic control.

[0055] In one embodiment, the high-performance CPU board 130 is used to acquire the current edge computing capabilities of the micro-loop and launch corresponding microservices based on these capabilities to control other relevant boards and insert other boards. For example, the high-performance CPU board 130 is a core board for complex edge computing business scenarios, integrating features such as multi-core CPU, high memory, and large-capacity storage. The high-performance CPU board 130 integrates containerized microservices. A daemon process communicates with the micro-loop capability baseboard 110 via Ethernet to acquire the current edge computing capabilities of the micro-loop and launches corresponding microservices based on these capabilities to control other relevant boards, thereby increasing data management efficiency.

[0056] In one embodiment, the power module board 140 integrates a power controller, providing DC / AC power (e.g., DC12V / 1A, AC24V, DC48V / 2A) output and power switch control to the corresponding board. For example, the power module board 140 can control the switch via the power output API. The data network board 150 integrates routing, data switching, and firewall functions, accessing Ethernet via an application programming interface (API) based on these functions. Additionally, the data network board 150 provides VLAN (Virtual Local Area Network), PPPoE (point-to-point protocol over Ethernet) dial-up protocol, routing and switching configuration service APIs, and firewall rule configuration APIs. The neural network computing board 160 integrates various neural network (e.g., NPU or TPU) computing units, receiving image information via Ethernet, analyzing and recognizing the image information, and outputting corresponding structured data, effectively increasing applicability.

[0057] In one embodiment, the cryptographic algorithm board 170 is used to integrate a cryptographic (e.g., HASH cryptography) security chip, providing interfaces for AES, RSA, and SM2 / 3 / 4 national cryptographic algorithms. The cryptographic security chip includes data encryption / decryption, signing, and verification functions applied to the basic smart pole service. These functions can be applied to a first electronic device (e.g., an LED device management platform for the basic smart pole service) and a second electronic device (e.g., an LED playback device for the basic smart pole service) associated with the basic smart pole service. The cryptographic security chip's data encryption / decryption, signing, and verification functions between the first and second electronic devices are as follows: After the first and second electronic devices exchange SM2 public key information, the second electronic device includes a first private key and a second public key, and the first electronic device includes a second private key and a first public key; the second electronic device uses the second public key to encrypt first information, and then uses the first private key to sign the encrypted first information to obtain first ciphertext; the first electronic device uses the first public key to encrypt second information, and then uses the second private key to sign the encrypted second information to obtain second ciphertext; the first and second electronic devices exchange the first ciphertext and the second ciphertext; the second electronic device uses the second public key to verify the second ciphertext, and then uses the first private key to decrypt the verified second ciphertext to obtain the second information; the first electronic device uses the first public key to verify the first ciphertext, and then uses the second private key to decrypt the verified first ciphertext to obtain the first information. The cryptographic algorithm board 170 of the edge computing system 100 proposed in this invention can be applied to data exchange processing between the first and second electronic devices, integrating the latest big data technology and blockchain technology to effectively enhance user experience.

[0058] In one embodiment, the streaming media codec board 180 is used to integrate multiple media (e.g., GPU or VPU) hardware computing units, which access and decode the video stream via the media hardware computing units, providing a YUV / JPG interface. For example, the IoT hardware interface expansion board 190 can be used to implement USB protocol to Ethernet protocol and RS485 protocol to Ethernet protocol conversion.
