Problems solved by technology

The country has promulgated and implemented a series of industry mandatory standards for the safety of public buildings. However, the gas fire alarm device and the electrical fire alarm device on the market currently appear individually. If only two separate alarm devices are selected, it will not be effective. Prevent the occurrence of fire; and the gas fire alarm devices and electrical fire alarm devices currently on the market only have an alarm function but no early warning function, and cannot broadcast the detected gas concentration value and remaining power value data in real time

Abstract

The invention discloses an electrical fire and gas intelligent monitoring and alarming system which comprises an external gas monitoring and controlling unit arranged in a gas concentration monitoringarea and an electrical fire and gas intelligent monitoring and alarming device arranged in a communication range of the external gas monitoring and controlling unit. The external gas monitoring control unit is in wireless communication with the electrical fire and gas intelligent monitoring alarm device through Zigbee. A real-time gas concentration value acquired by the external gas monitoring control unit is transmitted to a display screen of the electrical fire and gas intelligent monitoring alarm device, a voice broadcast function is provided, and a set of effective composite function technical solution is provided for early warning, alarm and control of residential gas fire and residential electrical fire.

Description

technical field [0001] The invention relates to the field of fire safety, in particular to an electrical fire and gas intelligent monitoring and alarm system. Background technique [0002] With the development of social economy and the in-depth application of electrical products, urban electricity consumption has been increasing year by year, and unsafe electricity consumption behaviors have gradually increased. "According to my country's fire statistics in recent years, the average annual number of electrical fires accounts 27% of the number of times, accounting for 80% of the total number of major fires, ranking first in the cause of fires, and losses accounted for 53% of the total fire losses. The country has promulgated and implemented a series of industry mandatory standards for the safety of public buildings. However, the gas fire alarm device and the electrical fire alarm device on the market currently appear individually. If only two separate alarm devices are selecte...
