RFID middleware system and method of supporting real-time balancing of loads of reader connections

摘要

Disclosed is radio frequency identification (RFID) middleware system and method of detecting the load of reader connections occurs during the middleware is running and balancing the load in real-time so as to minimize a decrease of the performance of the RFID middleware system. The RFID middleware system comprises: a client; a RFID middleware; RFID readers; and RFID tags, wherein the RFID middleware comprises: a middleware engine which filters tag events collected according to queries registered in the client; and a reader framework which detects the load of the connections of the RFID readers occurs while the RFID middleware is running and balances the load in real-time.

1. A radio frequency identification middleware system for supporting real-time load balancing of reader connections, the system comprising:
a client; a radio frequency identification middleware; radio frequency identification readers; and radio frequency identification tags, wherein the radio frequency identification middleware includes:
a middleware engine which filters tag events collected according to queries registered by the client; anda reader framework which detects the load of the connections of the radio frequency identification readers which occurs while the radio frequency identification middleware is running and balances the load in real-time, wherein the reader framework includes: adaptors which communicate with the radio frequency identification readers, receive tag data from the radio frequency identification readers, and convert the tag data into the tag events; an adaptor manager which creates and removes adaptors and receives tag events from the adaptors; and
a load diagnosing unit which detects the load of the adaptors generated due to the connection of the radio frequency identification readers and the load of the adaptor manager and balances the loads in real-time.
