Embodiment Construction
[0032] Below in conjunction with accompanying drawing and embodiment further illustrate the present invention.
[0033] figure 1 The structure of the RFID monitoring system of the first embodiment is shown, and the monitoring system is used to monitor the assembly conveyed on the assembly line, and the assembly is a semi-finished product assembled from a plurality of components, wherein at least two components have Corresponding RFID tags, anti-metal tags should be used in metal environments. like figure 1 As shown, the RFID monitoring system in the first embodiment includes: a monitoring component 1 , middleware 2 , and an application system 3 .
[0034] The monitoring assembly 1 is made up of a first monitor 11, a second monitor 12, a third monitor 13 and a fourth monitor 14, wherein the first monitor 11, the second monitor 12 and the third monitor 13 are RFID In the reader / writer, the fourth monitor 14 is a position sensor, specifically a photoelectric sensor, which is c...

The invention discloses an assembly line RFID monitoring system for monitoring assemblies. The assembly line RFID monitoring system comprises at least one monitoring assembly, a temporary database, a redundant filter and a judging device, wherein the monitoring assembly is correspondingly arranged on at least one monitoring position of an assembly line; each monitoring assembly comprises three RFID reader-writers and a position sensor, or only comprises three RFID reader-writers; the temporary database is used for storing the monitoring results of the RFID reader-writers and the position sensor; the redundant filter is used for filtering the redundant monitoring results of the RFID reader-writers and the position sensor; and the judging device is used for calculating the weighting monitoring result of each monitoring assembly respectively by using a redundancy-filtered monitoring result based on the unit of the monitoring assembly, comparing the weighting monitoring result and a judging threshold value, identifying workpieces passing through corresponding monitoring positions and outputting label data of the workpieces. According to the system, the judgment problems of over reading and misreading phenomena can be solved at the same time.
Description
technical field [0001] The present invention relates to an RFID monitoring system, and more particularly, to an RFID monitoring system for monitoring assemblies conveyed on an assembly line. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology, usually used to locate, identify, track, monitor and count. [0003] The application of RFID system in the assembly line of the manufacturing industry can solve the automatic reading of information in the assembly process and update the upper-level information system in real time. It has the advantages of improving the efficiency of assembly management, but its use also has relatively large limitations. , unintentionally blocked, improper label position, metal environment, liquid environment, etc.), sometimes it is difficult for the RFID tag to be read by the RFID reader 100%, and the phenomenon that the RFID tag is not read is called missed reading; due to the sensit...
