Method of automatic generation of internet-of-things data process flow based on RFID (radio frequency identification)

Abstract

The invention relates to a method of automatic generation of internet-of-things data process flow based on RFID (radio frequency identification). The method manly includes the steps of firstly, allowing for man-machine interaction to generate RFID data process flow, determining the required process according to needs, finally determining atomic processes of data processing, and sorting the atomic processes to obtain an atomic process sequence, configuring the number of the atomic processes according to resource conditions, and correlating the process to obtain a complete data process flow chart; secondly, automatically generating basic constraint conditions, automatically generating three constraint conditions, including cross-process item number constraint, item inclusion relation constraint and cross-process timing constraint, according to the generated data process flow chart; and thirdly, checking data completeness, namely checking the completeness of RFID data in real time, and sending out alarm in case of checked anomaly.

Description

technical field [0001] The invention relates to a method for automatically generating an RFID-based Internet of Things data processing flow. Background technique [0002] With the development of Internet of Things technology, RFID (Radio Frequency Identification) technology is playing an increasingly important role in the field of Internet of Things information collection due to its non-contact and fast data reading characteristics, and has been applied to various industries to item management , tracking, monitoring and other fields. For RFID applications in different industries, the basic data processing process is similar. They all input data from the RFID card reader, perform simple data processing, and then write it into the database. However, when it is implemented in a specific application, the data processing flow will be different. For each link of the process, there will be different configurations depending on the processing power / resources. The existing RFID in...

Problems solved by technology

However, RFID middleware is generally owned by RFID reader-writer providers, and they only provide basic application programming interfaces for users to call, which leads to the need for self-coded implementation of all custom data verification operations required by users

[0006] Although RFID middleware can perform simple fault-tolerant processing on RFID data, it cannot simply verify the global data from the perspective of the data processing flow of the entire system, so many basic / repeated data verification operations need to be manually written for processing. For example, data verification between adjacent data processing processes and data verification of different processing processes in the same data processing process
