| Summary: | 碩士 === 國立臺灣海洋大學 === 資訊工程學系 === 107 === The booming of the information industry accelerated the creation of many innovative and convenient Internet of Things (IoT) application themes. Electronic Shelf Labels (ESL) belong to one of the IoT application. The electronic shelf label has the function of displaying the product information on the paper shelf label, and at the same time, it has the networking capability. By systematically updating the product information on the screen, the time spent printing, checking and replacing the paper label replacement operation can be greatly reduced. Improve efficiency of the workers.
This paper implements the Electronic Shelf Label module and the back-end module management system to realize the module screen editing and preview function. The topology management relationship between the modules is clearly presented in the module management system, and assign the routing between each module through the MQTT protocol, update each module screen and control its LED.
The implemented Electronic Shelf Label module can form a wireless mesh network by itself. Each electronic shelf label module has a built-in laser ranging sensor that enables the electronic shelf label to collect customer attention. The method of collecting the degree of interest is converted into the basis for the customer's attention to the product by the time the customer observes or purchases the product. Attention data helps manufacturers understand the market competitiveness of commodities and can be used as a data reference for developing commodity sales strategies.
