Abstract
Description
Technical Field
[0001] This utility model relates to the field of Internet of Things (IoT) technology, and in particular to a novel IoT structure for vehicle monitoring. Background Technology
[0002] The Internet of Things (IoT) is a major driving force supporting a wide range of application services. It enables objects around us to communicate with each other via the Internet. The mainstream IoT architecture consists of three layers: the perception layer, the network layer, and the application layer. Sensors, actuators, RFID tags, and other smart terminals connect to the IoT from the perception layer. The network layer is responsible for communication between "things" and humans. The application layer provides a rich set of applications. Currently, there are many systems and interface devices on the market. However, most of them operate in specialized environments and can only access a very limited number of devices with dedicated interfaces. To address this issue, we designed and implemented a novel IoT access architecture for various IoT devices. On one hand, IEEE 1451.2 is used to support data acquisition from various sensors, actuators, and SoCs. On the other hand, we implemented this design using FPGA and SoC technologies, which allows for easy reconfiguration of the entire system while maintaining low power consumption.

[0016] Example
[0017] Please see Figure 1-2This utility model provides a technical solution: a novel Internet of Things (IoT) structure for vehicle monitoring, comprising a hardware structure and a software structure. The hardware structure includes a DDR, a GPS module, a USB interface, a system-on-a-chip (SoC), an Internet interface, a 4G module, a power supply, sensors, and a digital camera. The software structure includes an RSP, a Linux kernel, a Linux driver, a standard library, a third-party library, a data acquisition agent, a transmission management module, and a video acquisition agent. The output terminals of the DDR and GPS modules are electrically connected to the input terminals of the SoC. The USB interface is connected to the SoC. The Internet interface is connected to both the SoC and the digital camera. The power supply and sensors are both connected to the SoC. The USB interface is connected to the 4G module. The 4G module, power supply, and sensors are all connected to the RSP. The standard library and the data acquisition agent are connected. The third-party library and the video acquisition agent are connected. The digital camera and the Linux driver are connected.
[0018] Working Principle: In this application, the vehicle monitoring terminal primarily collects, processes, and transmits environmental information. Considering the system consists of a data acquisition module and a main module, the data acquisition module uses a lightweight standalone architecture, while the main module employs a high-performance Linux kernel. This design allows the entire system to operate with high performance and low power consumption.
[0019] For the data acquisition module, we designed an independent software system for sensor data acquisition, processing, and transmission based on the IEEE 1451.2 standard. After power-on, the system completes initialization and then enters a phase of waiting for requests from the main module. Upon detecting a request signal, the module determines the type of request signal and takes appropriate measures. For sensor data requests, the module addresses the specific sensor, performs data reading operations, and transmits the results to the main module. For TEDS data requests, the module addresses the specific TEDS and transmits the data to the main module. Furthermore, we implemented a self-test function to check the overall module status. The main module primarily performs system management, multi-data processing, and transmission. To achieve these functions, we compiled and ported the peta-Linux operating system, which provides various device drivers and libraries for application development. We designed and developed a data acquisition agent for retrieving sensor data from the data acquisition module and a video capture agent for retrieving video data from the digital camera.
