Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless positioning systems face issues with disordered data flows, susceptibility to data loss, and poor real-time performance during data transmission, particularly in ultra-wideband (UWB) positioning systems, which affect the scalability and accuracy of computing coordinates for positioning tags.
Innovation Solution
A method and apparatus for processing data flows in positioning base stations that utilize first and second identifiers to screen and order data packets based on type and time information, using frameworks like Apache Flume and Apache Flink to manage and process data packets, ensuring synchronization and accuracy in computing coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of positioning tags and base stations is increased to meet positioning service demand, then positioning coverage and service capacity are improved, but data flow disorder and real-time performance deteriorate
Solution Approach 1:
The patent segments the data flow processing by introducing identifier-based classification. Data packets are divided into different categories using first identifiers (data packet type) and second identifiers (time information), allowing parallel processing of different data types and improving overall processing efficiency while maintaining real-time performance despite increased system scale.
2Speed
If data packets are transmitted without ordering and synchronization, then transmission speed is improved, but data accuracy and coordinate computation reliability deteriorate
Solution Approach 1:
The patent applies preliminary action by embedding ordering information (identifiers) into data packets before transmission. The first identifier indicating data packet type and the second identifier indicating time information are added in advance, enabling the receiving end to quickly sort and synchronize data packets without affecting transmission speed, thus ensuring both speed and accuracy.
3Reliability
If data packets are screened and sorted using multiple identifiers, then data accuracy and synchronization are improved, but processing complexity increases
Solution Approach 1:
The patent uses identifiers as intermediary elements to bridge the gap between simple transmission and complex processing. The first identifier (data packet type) and second identifier (time information) act as mediators that carry essential sorting information without requiring complex processing logic, simplifying the overall system while ensuring reliable data synchronization.

AI summary
The present disclosure relates to a method and an apparatus for processing a data flow of a positioning base station, a device and a computer readable medium. The method includes: extracting, under the condition that a data packet to be processed which is sent by the positioning base station is received, a first identifier carried in the data packet to be processed; screening out a first data packet by using the first identifier, where the first data packet is a data packet to be processed including a distance from the positioning base station to a target position; extracting a second identifier carried in the first data packet, where second identifiers carried in different data packets to be processed sent by the same positioning base station vary; and determining, under the condition that time indicated by the second identifier is target time, the first data packet as a target data packets.
