TH6929C3 - Wireless Electronic Price Signage System - Google Patents

Abstract

DC60 (27/12/54) Wireless electronic product price information display system consists of 3 parts: computer control system, signal distribution machine. And a sign showing product price information, which can order work to change product prices from a computer controlling system Which will be broadcast as well Public frequency broadband broadband for industrial, scientific and medical (ISM band) broadband broadband broadband (ISM band) with a unique communication format designed. To change The product price tag can display product price information wirelessly. By displaying price results with a liquid crystal glass (LCD glass), a wireless electronic product price display label consists of 3 parts: a computer control system. Signal diffuser And a sign showing product price information, which can order work to change product prices from a computer controlling system Which will be broadcast as well Public band broadcasters for industry, science and medicine (ISM band) with a data communication format. Specifically designed To change The product price at the end shows the product information wirelessly. By displaying price results with liquid crystal glass (LCD glass)

Claims (1)

1. Wireless Electronic Price Signage System It consists of - Computer control system (1) that serves to send product price information to a signal distribution machine (3) with a serial data connection standard (RS232) (2) - Distributor (3) acts as Receive product price information from the computer control system (1) to bring product price information to broadcast signal to the price information bar. Wireless Electronic Products (4) Include - Microcomputer Trollers (Microcontroller) (7) serves to control the operation of Spreader - A standard serial connection (2) interface converts the signal from Serial connection standard (RS232) to a level that can communicate with Microcontroller (Microcontroller). - Radio communication device (RF Module) (8) serves to communicate with radio signals. - Display compared to the liquid crystal display (LCD) Module) (9) serves to display status. Of the diffuser The operation of the diffuser (3) is started from the microcontroller.
