Design and Research of Electric Bicycle Networking System Based on NB-IoT Technology

With the development of cities, more and more problems have been exposed, and the consumption concept of green travel has become more and more popular. The public Internet of Things electric bicycle system includes perception level, central control level, data processing level, system service level and system management level. Perception level is used to collect public bicycle equipment and citizen bicycle rental IC card information. The central control completes networking, sends and receives perception level information, and processes data conversion information. Data processing is used to create and manage system databases, as well as to classify and process data. All application functions related to users of the public bicycle system: The system management level is used to handle all operating system management and maintenance personnel related to the public bicycle system. Based on the analysis of the narrowband Internet of Things NB-IoT technology, this article combines the advantages of enhanced coverage, large links, low power consumption, and low cost of the technology, and adopts a three-layer architecture to propose an electric bicycle system based on NB-IoT. The current electric bicycle system has disadvantages such as poor real-time performance and high power consumption, and saves resources. Through experiments, the scale of the system can be dynamically configured, which greatly reduces the communication pressure on the system background, and at the same time makes the system's transmission rate of different communication distances reach 99% on average, and the average delay reaches 7s. The real-time performance of the system is still a certain problem.
