城市停车泊位余位数据

数据可用于查询城市内某路段泊位的余位情况，应用场景包括：政府决策分析、交通管理系统、第三方客户端软件数据查询等。当车辆驶入或驶出停车位时，安装在此停车位上的地磁车位检测器检测到磁场变化，判断有车还是无车，将判断后的数据通过NB-IoT实时传输到云平台， 平台解析数据并根据数据库中存储的车位设备关系表，找到对应所属的车位编号和路段信息，根据数据更新车位的状态。有车状态将该路段占用泊位数量+1，无车状态将该路段占用泊位数量-1。 平台每间隔一小时按照省份、城市、路段的层次从数据库检索，获取每个路段泊位总数和查询时刻的空闲泊位数量、占用泊位数量，然后将省份、城市、路段、日期、统计时间、泊位总数、空闲泊位、占用泊位数据存储到数据库中供后续查询。

This dataset can be used to query the remaining available parking spaces for a specific road segment within a city. Its application scenarios include government decision-making analysis, traffic management systems, data query services for third-party client software, and other related fields.
When a vehicle drives into or out of a parking space, the geomagnetic parking space detector installed on that parking space detects changes in the magnetic field, determines whether the space is occupied or vacant, and transmits the judgment result data to the cloud platform in real time via NB-IoT. The cloud platform parses the received data, and according to the parking space-equipment relationship table stored in the database, identifies the corresponding parking space number and road segment information, then updates the parking space status. If the status is occupied, the number of occupied parking spaces for this road segment increases by 1; if the status is vacant, the number of occupied parking spaces for this road segment decreases by 1.
The platform retrieves data from the database at one-hour intervals in the hierarchical order of province, city, and road segment, obtaining the total number of parking spaces, the number of vacant parking spaces, and the number of occupied parking spaces at the query timestamp for each road segment. It then stores the data including province, city, road segment, date, statistical time, total parking spaces, vacant parking spaces, and occupied parking spaces into the database for subsequent query operations.
