A smart parking system based on NB-IoT and third-party payment platform

In recent years, with the increasing number of vehicles and insufficient parking spaces, the urban traffic congestion has become a great challenge that cannot be neglected. In order to mitigate problems such as high power consumption of sensor node and high deployment costs of wireless network, a smart parking system is proposed in this paper. In the proposed system, the data of the sensor node is transmitted by Narrowband Internet of Things (NB-IoT) module, which is a new cellular technology introduced for Low-Power Wide-Area (LPWA) applications. Basic information management, charge management, sensor node surveillance, task management and business intelligence modules are implemented on the cloud server. With integrated third-party payment platform and parking guide service, the mobile application developed for drivers is easy and convenient to use. Currently, the proposed system has been deployed in two cities to improve the utilization of existing parking facilities effectively.
