Design of Intelligent Parking Lock for Road Parking Based on NB-IoT

With the increasing of car ownership, urban parking spaces can not meet the parking demand, so the problem of parking difficulty is prominent. In order to solve this problem, roadside parking spaces are planned on both sides of many urban roads, which alleviates the problem of parking difficulty to a certain extent. For such roadside parking spaces, most of them are managed by the combination of parking pile and manual work. But there are some problems, such as high management cost, no payment by car owners, low charging rate, serious capital loss and low utilization of parking spaces. In order to solve the above problems in the management of roadside parking spaces, in this paper, an intelligent parking lock for road parking based on the narrow-band Internet of things (short for NB-IoT) is designed, which is used in conjunction with the parking pile. After tested, the designed parking space lock can realize the vehicle detection function. At the same time, the parking space lock is connected to the upper computer through the NB-IoT module, which can realize the functions of remote control and status monitoring of parking space lock, and meet the design requirements.
