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

[0052] A block diagram of the circuit structure of a restaurant fire alarm control system figure 2 shown. Includes centralized controller and multiple regional controllers. The centralized controller is composed of a signal sending terminal A, a signal receiving terminal B, a network interface module 2 , a keyboard display module 10 and a microcontroller module 1 . Both the regional controller and the fire extinguishing controller include a signal sending terminal A, a signal receiving terminal B and a microcontroller module 1 , wherein the regional controller also includes a smoke detector 11 . The centralized controller communicates with the regional controllers through the power line. The server of the terminus is the computer management system located on the top layer, which is composed of routers and computers.

[0053] The hardware structures of the power line communication signal sending end A, signal receiving end B, microcontroller module 1 and power supply module...

Abstract

The invention relates to a fire alarm control system for restaurants. Fire disasters are easily caused in most fields concentrated with restaurants. A zone controller is arranged each or several restaurants, and an integrated controller is arranged in a firefighting room; a plurality of smoke detectors are arranged at the top of each room and fire-prone areas of a restaurant, the zone controller is used for transmitting fire information to the integrated controller for treatment through power line communication, and the integrated controller is communicated with a fire-extinguishing controllerthrough a power line and is accessed to the internet through a network interface module to form network interconnection with the server of a fire-fighting center.

Description

(1) Technical field: [0001] The invention relates to a fire alarm control system for a restaurant, which includes a centralized controller and regional controllers, and adopts a power line communication method to send a wide pulse signal to a specific point where the grid cycle voltage crosses 0 to generate a sudden change current, so that the grid cycle carries information. The centralized controller receives the data collected by the regional controllers, 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 transmit signals through carrier wave. However, the distribution tra...
