Gas detection and alarm system based on RF wireless communication

Abstract

The invention belongs to the field of industrial control, in particular to a gas detection and alarm system which applies a RF wireless carrier communication module to transmit alarm information. The system comprises gas detectors, monitoring equipment and a power line carrier communication module, and is characterized by comprising a plurality of gas detectors; and the monitoring equipment can sample the data of the gas detectors through the power line carrier communication module. Consequently, when a user uses the system, a gas detection an alarm controller and the gas detectors are not necessarily connected, and the data information can be transmitted only by the RF wireless carrier communication module; and the system has the advantages of simple structure, low cost, low one-time investment, convenient installation, convenient operation and maintenance management, and can be widely applied to the gas leakage monitoring of fire control, petrochemical, urban gas and other fields. The advantages of the invention can be more displayed on occasions between some controllers and detectors on which wiring cannot be realized.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a gas detection and alarm system using an RF radio carrier communication module to transmit alarm information. Background technique [0002] With the continuous progress of society, the living standards of our people are also constantly improving. There are a variety of gas detection and alarm systems in modern society. The data communication between these gas detection and alarm system equipment generally adopts 485 and CAN communication protocols. The installation and construction bring a lot of troubles and the cost of installation and wiring is high. And in some occasions, there is no wiring between the controller and the detector, so the existing gas detection and alarm system cannot be applied to relevant occasions. [0003] Based on the deficiencies of existing gas detection and alarm system equipment, the inventors developed the present invention "a gas detection and a...
