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 fire hazard alarm control system which comprises fire hazard detectors, regional controllers, a concentrated controller and a fire extinguishing controller. After power-on,the regional controllers registers the fire hazard detectors, and raises alarm when a fault is found. Each fire hazard detector grades a detected fire alarm signal and then sends alarm information tothe corresponding regional controller, and the regional controllers raise alarm to the concentrated controller via power line communication according to the position and grade of the fire alarm, and the concentrated controller starts fire extinguishing apparatuses and emits alarming sound via power line communication or by starting the fire extinguishing controller.

Description

(1) Technical field: [0001] The invention relates to a fire alarm control system, which includes a centralized controller and various regional controllers, and uses a power line communication method to send a wide pulse signal to a specific point in the grid cycle voltage crossing 0 area to generate a sudden change current, which is used as a bit value of the signal, and the centralized The controller receives the data collected by each regional controller, and accesses 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 h...
