Abstract
The utility model relates to the field of industrial control, in particular to a gas detection alarm system for transmitting alarm information by applying an RF (Radio Frequency) radio carrier wave communication module. The system comprises gas detectors, monitoring equipment and a power line carrier wave communication module. The system is characterized in that a plurality of gas detectors are provided, and the monitoring equipment can sample gas detector data by the power line carrier wave communication module. The system has the advantages that in the process that a user uses the system, data information transmission can be realized only by utilizing the RF radio carrier wave communication module without directly wiring a gas detection alarm controller with the gas detectors. The system has simple structure, low cost, less one-time investment and convenient installation, operation, maintenance and management. The system can be widely applied to gas leakage monitoring in the fields of fire control, petrochemical industry, city gas and the like. The advantages of the system can be better shown in some occasions where wiring can not be realized between the controllers and the detectors.
