Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0046] Such as figure 1 The illustrated embodiment is a communication method for an electronic shelf label system, the electronic shelf label system includes a server 1, 10 readers 2 and active label groups 3 corresponding to the readers; The reader is electrically connected to the active tag group through a wireless method; the active tag group is composed of 200 active tags 4.
[0047] Such as figure 2 shown, including the following steps:
[0048] Step 100, set the ID number corresponding to each active tag in the active tag group, 200 ID numbers of each active tag group form an ID group, store the ID group of each active tag group in the server and in each reader;
[0049] In step 200, the wireless chip of the active tag is alternately in a dormant state and an active state, and the dormant time is 6 seconds, and the active time is 3 m...

The invention discloses an electronic goods shelf label system communication method. An electronic goods shelf label system comprises a server, at least on reader and an active tag label group corresponding to the readers. The server and the readers are connected in a wired or wireless mode, the readers are electrically connected with the active label group in a wireless mode, and the active label group is composed of a plurality of active labels. The communication method uses frequency division multiple access (FDMA) and time division multiple access (TDMA) into the electronic goods shelf label system and effectively solves the problems that a traditional electronic goods shelf label system is low in update efficiency of data and poor in reliability, sent data cannot be received easily, data request information are prone to lose, and data are prone to jam in loading.
Description
technical field [0001] The invention relates to an electronic shelf label system, in particular to a communication method of the electronic shelf label system capable of ensuring that updated data is received reliably and orderly. Background technique [0002] The network composition of the electronic shelf label system using active tags is similar to that of the traditional wireless communication network. The tag is equivalent to a general-purpose mobile phone, the reader is equivalent to a base station, and the server is equivalent to a base station controller and network management. [0003] The frequency band of the electronic shelf label system refers to the frequency range of the label signal sent, received and identified by the reader through the antenna. In the electronic shelf label system, the system works similar to the way people listen to FM radio, and the active label and the reader must be modulated to the same frequency to work. [0004] According to intern...
