However, traditional small posture sensors are usually not equipped with processing modules and lack the hardware foundation for edge computing. They are mainly used externally and need to rely on the cloud, which increases latency and bandwidth requirements, resulting in data transmission delays and long processing time, and cannot meet real-time requirements. Against the background of the rapid development of the Industrial Internet of Things, edge computing in the Industrial Internet of Things environment is gaining increasing attention as an emerging technology; edge computing emphasizes processing and analysis where data is generated to reduce data transmission delays, improve system response speed, and reduce network bandwidth consumption.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances. This is just a way of distinguishing objects with the same attributes when describing the embodiments of this application.

[0024] In some embodiments, the edge-end posture data acquisition device for the industrial Internet of Things includes an edge-end posture data acquisition main device, and the edge-end posture data acquisition main device includes a main controller, a first posture data acquisition circuit, a temperature and humidity acquisition circuit, a GPS module, a first LORA communication circuit and a ZigBee communication circuit, wherein:

[0027] It can be understood that the near-end device refers to a device that can communicate with the edge-end posture data acquisition main device at a short distance, such as the edge-end posture data acquisition sub-device in Example 2. The remote device refers to a device that can communicate with the edge-end posture data acquisition main device at a long distance, such as a background server or a host computer.

[0028] As attached Figure 2 and attached Figure 3 As shown, the AUX pin of the first LoRA communication circuit is connected to the PA8 pin (LORA_AUX) of the main controller, the RX pin of the first LoRA communication circuit is connected to the PB10 pin (LORA_RX) of the main controller, the TX pin of the first LoRA communication circuit is connected to the PB11 pin (LORA_TX) of the main controller, the M1 pin of the first LoRA communication circuit is connected to the PB12 pin (LORA_M1) of the main controller, and the M0 pin of the first LoRA communication circuit is connected to the PB13 pin (LORA_M0) of the main controller.

[0029] As attached Figure 2 As shown, the ZigBee communication circuit adopts the E18-MS1-PCB communication module U4, the 14th pin (NWK_LED) of the E18-MS1-PCB communication module is connected to the PA1 pin (Zig_NWK) of the main controller, the 11th pin (RX) of the E18-MS1-PCB communication module is connected to the PA2 pin (Zig_RX) of the main controller, the 10th pin (TX) of the E18-MS1-PCB communication module is connected to the PA3 pin (Zig_TX) of the main controller, the 7th pin (at_hex_key) of the E18-MS1-PCB communication module is connected to the PA4 pin (Zig_MOOE) of the main controller, and the 12th pin (RUN_LED) of the E18-MS1-PCB communication module is connected to the PA5 pin (Zig_RUN) of the main controller. It can be understood that the ZIGBEE communication circuit used by the edge-end posture data acquisition main device supports the Zigbee protocol, which is suitable for short-distance, high-speed data transmission and can be used for communication between devices within the local area network, which is helpful for the subsequent communication and interconnection between the main device and the sub-devices.

[0030] It should be noted that the utility model includes an edge-end posture data acquisition main device, which aggregates a main controller, a first posture data acquisition circuit, a temperature and humidity acquisition circuit and a GPS module. It not only has the hardware foundation for edge-end processing, reducing dependence on the central server, but also can provide carrier posture data, environmental temperature and humidity data corresponding to the carrier, and carrier position data to meet subsequent refined analysis needs.

[0031] In some embodiments, as shown in the attached Figure 2 As shown, the first posture data acquisition circuit includes an MPU9250 posture sensor, a capacitor C8, a capacitor C13 and a capacitor C15, the SDA pin (pin 24) of the MPU9250 posture sensor is connected to the PB7 pin (MPU_IIC_SDA) of the main controller; the SCL pin (pin 23) of the MPU9250 posture sensor is connected to the PB6 pin (MPU_IIC_SCL) of the main controller;

[0033] It should be noted that the reason why the first attitude data acquisition circuit selects the MPU9250 attitude sensor U3 is that it has a comprehensive angular velocity sensing range, including ±250, ±500, ±1000 and ±2000° / sec (dps), so that it can accurately track fast and slow movements. The first attitude data acquisition circuit collects the acceleration, angular velocity and magnetic field strength data of the carrier's X, Y, and Z axes, and transmits the data to the main controller for subsequent data aggregation and analysis.

[0034] In some embodiments, the temperature and humidity acquisition circuit includes a temperature and humidity sensor SHT20, a resistor R11, a resistor R12, a capacitor C21, and a capacitor C22; the SDA pin (pin 1) of the temperature and humidity sensor is respectively connected to one end of the resistor R11 and the PA14 pin (SH_SDA) of the main controller, the SCL pin (pin 6) of the temperature and humidity sensor is respectively connected to one end of the resistor R12 and the PA15 pin (SH_SCL) of the main controller, and the other end of the resistor R11 and the other end of the resistor R12 are both connected to a power supply of 3.3V;

[0036] It should be noted that the temperature and humidity acquisition circuit acquires the ambient temperature and humidity data corresponding to the carrier, and provides real-time data of ambient temperature and humidity for subsequent carrier status analysis.

[0037] In some embodiments, the model of the GPS module is ATGM336H, as shown in the attached Figure 5 As shown; it should be noted that the GPS module connected to the main controller can provide accurate geographic location information to ensure the positioning and path planning accuracy of the equipment. The combination of the temperature and humidity sensor SHT20, the GPS module and the attitude sensor can effectively support the real-time monitoring and management of the equipment attitude, tilt angle and position status, and provide comprehensive reference data for industrial and transportation applications.

[0038] In some embodiments, the main controller uses an STM32 L series microcontroller, such as STM32L151CCT6, which has significant advantages in the resource-limited edge field due to its low power consumption. It is small and powerful, has its own power supply, and has low power consumption. It can support long-term use of nodes without charging, thereby enhancing the portability and durability of edge attitude data acquisition equipment for the industrial Internet of Things.
