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

Abstract

The invention relates to a remote control system for electric appliances in a hotel. An electronic switch in a hotel electric appliance controller controls the start / stop of the electric appliances, and the electronic switch is in parallel connection with an electric appliance switch. A centralized controller and an electric appliance controller employ power lines for communication. The centralized controller is connected to the Internet through a network interface module. A tourist can use a laptop and handheld mobile equipment for access to a general computer management system for related operation.

Description

(1) Technical field: [0001] The invention relates to a remote control system for electrical appliances in a hotel, which includes a centralized controller and controllers for various electrical appliances, and uses a power line communication method to send a wide pulse signal to a specific point where the cycle voltage of the grid passes through 0 to generate a sudden change current, so that the cycle of the grid carries information. The centralized controller receives the data collected by each electrical controller, and connects to the Internet through the network interface module integrated with the TCP / IP hardware protocol stack, so that computers and handheld mobile devices can be used to access the remote computer management system. (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 transmi...
