City district combustion gas security protection monitoring system

Abstract

Disclosed is a city district combustion gas security protection monitoring system. The system comprises two parts, i.e., owner units and a property monitoring center. The system owner units are composed of single-chip microcomputer control modules (1), combustion gas temperature sensing modules (2), signal processing modules (3), solenoid valve modules (4), acousto-optic alarm modules (5), wireless data sending modules (6), information input modules (7) and power modules I (8) and are placed in the homes of owners. The system monitoring center is composed of a wireless data receiving module (9), a monitoring processing module (10), a monitoring acousto-optic alarm module (11), a short message sending module (12) and a power module II (13) and is placed in a property management monitoring room. By using the system, the combustible gas content of each owner, and whether a dry pan is accidentally extinguished or a gas cooker is accidentally extinguished during water boiling or cooking of each owner can be monitored in real time, if such information is abnormal, an indoor gas valve is automatically closed, an acousto-optic alarm is given, leakage information is transmitted to the property monitoring center in a wireless mode, in case of absence of personnel on duty in the monitoring center for handling, the personnel on duty can be notified through short messages, the short messages can also be sent to the owners for notification about combustion gas leakage, and in case of a fire hazard, the 119 fire alarm telephone number is automatically dialed.
