Problems solved by technology

In battery-operated or battery-operated relay stations, this leads to the fact that the energy store must be replaced or filled at non-uniform time intervals
Uneven energy requirements and a large number of repeaters lead to a high failure rate in the system and require high maintenance costs to avoid

Embodiment Construction

[0063] exist figure 1 An electronic shelf label system 1 is shown in , which is hereinafter referred to as system 1 for short. System 1 has 4000 shelf label clients 2 , referred to as clients 2 hereinafter, and 4 access points 6 . Each access point 6 has an individual radio coverage area 131-134, wherein the four radio coverage areas 131-134 partially overlap. The access point 6 as well as the client 2 support WLAN according to the standard specification IEEE802.11b / g / n. The access points 6 use the 2.4GHz ISM radio band for their radio communication, where the ISM radio band stands here for "Industrial, Scientific and Medical Radio Band" and each access point 6 uses a different radio channel. Within the first radio coverage area 131 , 1000 clients 2 are represented by squares and are associated via the first radio channel with the first access point 6 visualized in the center of the first radio coverage area 131 . Within the second radio coverage area 132 , 1000 clients 2 a...

Abstract

Electronic shelf tag system that has: at least one battery-operated shelf tag client that has an energy-saving sleep mode without radio communication standby according to a radio standard and an active mode with radio communication standby according to the radio standard and that has a radio wake-up receiver designed so as, on receiving a wake-up signal, to leave the sleep mode and prompt the active mode to be adopted, and an access point that is designed for radio communication with the at least one shelf tag client according to the radio standard and that has a radio wake-up transmitter for transmitting the wake-up signal, wherein the radio wake-up transmitter is designed to be controllable in terms of the time at which the wake-up signal is transmitted by the access point, and the access point defines the time as the initiation of a radio connection setup to the at least one shelf tag client according to the radio standard, in particular with a lead time for changing from the sleep mode to the active mode.

Description

technical field [0001] The invention relates to an electronic shelf label system with a standardized radio communication protocol. Background technique [0002] An electronic shelf labeling system in which a standardized radio communication protocol is used is known, for example, from US 2018 / 0270734 A1. The system has a plurality of shelf labels and an access point for radio communication with the shelf labels. The access point supports WLAN. The shelf labels are Bluetooth enabled. Between the access point and the shelf labels, the relay station acts as an access node for the group of shelf labels logically associated with the relay station. The repeater supports WLAN so it can communicate with the access point and Bluetooth so it can communicate with the shelf labels. [0003] The relay stations together with their associated shelf labels form a multi-hop network in which information determined for a particular shelf label is first received by the relay station and the...
