Smart parking techniques are widely used in smart city and intelligent transportation systems. However, how to build a friendly and effective smart parking system in a large city is still a challenge. This paper proposes a P2P network based smart parking system using Edge Computing. It utilizes Cloud Computing, Edge Computing, and P2P network techniques to provide plenty of services including parking space inquiry, navigation, vehicle license plate recognition, payment, and accident query. The architecture of the system and the related protocols and algorithms are presented in detail. Compared with the existing smart parking systems, the proposed system is more friendly and effective.

智能停车技术被广泛应用于智能城市和智能交通系统中。然而，如何在大城市中建立友好而有效的智能停车系统仍然是一个挑战。本文提出了一种基于边缘计算的基于P2P网络的智能停车系统。它利用云计算，边缘计算和P2P网络技术来提供大量服务，包括停车位查询，导航，车牌识别，付款和事故查询。详细介绍了系统的体系结构以及相关的协议和算法。与现有的智能停车系统相比，该系统更加友好有效。
