POI海事航标（灯桩）导航数据

灯桩是一种柱状或铁架结构的建筑物，一般设置在航道附近的岸边，以及港口防波堤上。灯桩的灯光强度不及灯塔，一般无人看管。在实际的船舶进航行过程中，通常用物标来作为定位依据，保障航行安全，但在实际过程中，难以用肉眼查找到相应的物标。POI海事航标（灯桩）导航数据应用于海上导航APP，详细的显示了数据对应的相关属性信息，用户能够及时查看数据信息，提醒用户根据导航数据及时对照物标，充分保障了航行安全。数据内容以每周更新的形式，按照数据类型，在我司后台上进行点位标记，并记录相关属性。灯桩的每个属性数据按标记语言的方式用ASCII码和汉字内码描述。每一个属性项之后,以十六进制数 1F 结束。多个属性项构成一个物标的全部属性记录，以十六进制数 1E 终止。数据采用B+数据结构进行存储，生成一组导航系统的目录管理数据库,用于对导航系统的检索、分析和查询，B+树存储结构大大提高了数据检索的效率。数据查找关系：每条索引开始地址=(序号-1)X84 字节；每个物标的实体数据地址=该物标索引中查到的数据地址；每个物标的实体数据长度=该物标索引中查到的数据长度，并读取关于物标的控制信息和说明信息和属性信息。通过数据采集、处理、加工及存储的一系列过程，在海上导航APP上展示最新灯标数据及相关属性，用户也可以搜索灯标历史数据，能够提前了解航线上的物标，提醒用户根据导航上的数据及时对照物标，充分保障了航行安全。

A light beacon is a columnar or steel-framed structure, typically installed on shores near shipping lanes and port breakwaters. The luminous intensity of a light beacon is lower than that of a lighthouse, and it is usually unmanned. In actual ship navigation, visual beacons are often used as positioning references to ensure navigation safety, yet it is difficult to locate the corresponding targets with the naked eye.

The POI maritime navigation beacon (light beacon) navigation data is applied to maritime navigation apps, which displays detailed relevant attribute information corresponding to the data. Users can view the data information in a timely manner, and are reminded to promptly compare with the corresponding beacons based on the navigation data, thereby fully ensuring navigation safety.

The data content is updated weekly, with point markers created on our company's backend according to data types, and relevant attributes are recorded. Each attribute data of the light beacon is described using ASCII codes and Chinese character internal codes in a markup language format. Each attribute item is terminated by the hexadecimal number 1F. All attribute records of a single beacon are composed of multiple attribute items, and are terminated by the hexadecimal number 1E.

The data is stored using a B+ tree data structure, which generates a directory management database for navigation systems used for retrieval, analysis and query. The B+ tree storage structure greatly improves the efficiency of data retrieval.

Data lookup rules: The start address of each index = (serial number - 1) × 84 bytes; the entity data address of each beacon = the data address retrieved from the index of this beacon; the entity data length of each beacon = the data length retrieved from the index of this beacon, and the control information, description information and attribute information of the beacon are read.

Through a series of processes including data collection, processing, manipulation and storage, the latest beacon data and related attributes are displayed on the maritime navigation app. Users can also search for historical beacon data to understand the beacons on their route in advance, remind users to timely compare with the beacons based on the navigation data, and fully ensure navigation safety.
