Embodiment Construction
[0020] The basic idea of the present invention is: set a tag cache consisting of a shielding cache and a sending cache on the reader side, use the shielding cache to realize the tag filtering function, and shield the tags that are repeatedly counted and reported within the set shielding period; use the sending cache to cache The generated tag event data will report several short messages in a unified manner.
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 As shown, the present invention is provided with a tag buffer on the reader side of the RFID system, and the tag buffer includes two storage sub-areas, namely, shielding buffer 1 and sending buffer 2 . Among them, shielding buffer 1 is used to store tag status data, which can realize the tag filtering function, and shield the tags that are repeatedly counted and reported within the set shielding period...

The invention discloses a device for realizing label counting in a radio frequency recognition system. A label cache consisting of a shielding cache and a transmitting cache is arranged at a reader side, wherein the shielding cache is used for shielding repeatedly reported labels in a set shielding period, and the transmitting cache is used for caching generated label event data and uniformly encapsulating and reporting all the cached label event data when a transmitting period is due. The method of the invention comprises the following steps: when counting a label, judging the label state of the label, determining whether to change the label state according to the judging result, and determining whether to generate label events; caching the generated label event data; reporting all the cached label event data together when the transmitting period is due or the cache is full; and executing counting of the next label when the transmitting period is not due. The device and the method can be used for realizing a label filtering function, can avoid frequent report of data, and reduce the number of short messages in a network, thereby being favorable for quickly and effectively transmitting data.
Description
technical field [0001] The invention relates to the field of radio frequency identification (RFID), in particular to a device and method for realizing tag counting in an RFID system. Background technique [0002] RFID technology mainly uses wireless methods to identify tags. Its identification function is mainly completed by readers and tags. The reader identifies one or more tags and sends the read tag information to the upper system for data processing. Generally, the upper layer data processing system is called middleware system. In the actual application of RFID technology, usually a middleware system will be connected to several radio frequency collection devices, that is, readers of various types. After the reader collects and counts the tag information, it will report it to the middleware system The next step is to deal with it uniformly. When the amount of data counted by each reader is large, the data flow reported to the middleware system will form a peak, which ...
