Description
Technical Field
The invention relates to the technical field of logistics tracking, in particular to a logistics tracking query method of a logistics vehicle capable of being positioned.
Background
With the rapid development of the internet, especially the rapid development of the mobile internet, the types of activities performed by people via the internet are more and more diversified, and ways to engage in various activities are more and more, in this case, not only the connections between various activities are more and more close, but also different ways to engage in the same activity contain similar data. It has become an urgent need to integrate and display or further analyze data of different types of activities closely related to each other and data of different ways of engaging in the same activity.
For example, in the field of logistics warehousing, as individual consumers use express delivery more and more frequently, and the types of trades are expanded and the geographical range of trades is globalized, more and more logistics companies are derived to provide corresponding logistics services. In addition, as the communication of people becomes more convenient and the development of logistics companies is strong, the value of goods carried by each logistics company is greatly improved in recent years, and the occupied proportion of cross-border logistics is also greatly improved. In addition, for individual consumers or other users who enjoy logistics services, they usually select or use different logistics companies through different internet services, and especially for cross-border logistics, the freight cost not only relates to traditional data such as cargo weight and mileage, but also relates to data related to the price, type, usage, etc. of the cargo itself and the internet services. Meanwhile, the transportation capacity and other information of each logistics company can be comprehensively analyzed based on the logistics data. Therefore, the logistics warehouse data is oriented to objects including not only consumers and other users, but also various internet-based services, and particularly, in cross-border logistics, there is an intersection with information of various internet-based services.
A large amount of logistics data is usually acquired from the logistics systems of the logistics companies and stored in a designated logistics information storage database system, and one important characteristic of such a database system is that the data size is large, a plurality of data sources are provided, each data source is frequently refreshed, and a large amount of logistics data needs to be provided to a series of logistics data users. Meanwhile, the large amount of logistics data often intersects or is associated with non-logistics data owned by a logistics data user, so that the non-logistics data owned by the logistics data user is often stored in a designated logistics information storage database system according to needs. Therefore, the designated logistics information storage database system is a database system formed based on logistics systems of a plurality of logistics companies, and the database system needs to provide logistics data belonging to each logistics company for a user, integrate the logistics data with non-logistics data owned by the user and perform personalized customization, and needs to ensure the accuracy and timeliness of the data.
In the prior art, multiple software needs to be maintained simultaneously by multiple parties, and the problem that the software is easy to operate and configure due to the mutual cooperation of the software is considered, and the problem positioning by multiple personnel is difficult; every time a new logistics company is added for access, the work of code development and joint debugging test needs to be repeated, and the flexibility of later maintenance and expansion of the system is not high. Particularly, in the process of distributing objects, due to the fact that the objects are various in style and the environments for distributing the objects are various, firstly, the quality of the objects, such as damage of commodities in different temperature environments, is difficult to monitor and track, and moreover, due to the fact that the assembling quality of the objects are difficult to unify due to different shippers, the objects are often difficult to track.
