Problems solved by technology

[0004] The detection of TW A CS signals is mainly based on time-domain difference technology. Most of these methods have complex data processing, poor real-time performance, and high equipment costs. In order to determine whether the signal bit is "1" or "0", due to the rigor of the calculation, the interference signal will seriously affect the judgment result of the detected signal, so the original method is difficult to apply in our country

Embodiment Construction

[0053] The block diagram of the circuit structure of a chain store customer inquiry system is as follows: figure 2 shown. It consists of a centralized collector and multiple commodity recorders. The centralized collector is composed of a signal sending terminal A, a signal receiving terminal B, a 4G wireless router 2, a keyboard display module 10 and a microcontroller module 1. The commodity recorder is composed of a signal sending terminal A, a signal receiving terminal B and a microcontroller module 1, and the commodity recorder records the information of commodities 11. The centralized controller communicates with the product recorder through the power line. The terminal is the computer management system located on the top layer, which is composed of 4G wireless router, microcontroller module and computer.

Abstract

The invention relates to a chain store customer inquiry system. The store is divided into a number of commodity areas by product type; each commodity area comprises a plurality of shelves; several shelves share one commodity entry instrument; and the commodity entry instrument communicates with a centralized collector by using a power line. The centralized collector is connected to a mobile wireless communication network through a 4G wireless router; managers and customers can use mobile APPs, computers and handheld mobile devices to learn the details of the commodities of all stores no matterwhere they are.

Description

(1) Technical field: [0001] The invention relates to a chain store customer query system, which includes a centralized collector and various product recorders, and uses a power line communication method to send a wide pulse signal to a specific point in the grid cycle voltage crossing 0 to generate a sudden change current, which is used as a bit value of the signal. The centralized collector receives the data collected by each commodity recorder, and connects to the 4G mobile wireless communication network through a wireless router, so that no matter where you are, you can use mobile phones, computers and handheld mobile devices to realize wireless networking. (two) background technology: [0002] Current power line communication mainly refers to power line carrier communication and two-way power frequency communication. Power line carrier communication PLC uses the existing power line to transmit signals through carrier wave. However, the distribution transformer has a blo...
