Problems solved by technology

But in general, there are still some deficiencies. The early warning and monitoring system before the fire is underdeveloped. Usually, people first discover it and take measures after calling the police. It's just that it is too late when people find out, and the fire has developed to an unstoppable level. controlled
As a result, irreparable loss of life and property

Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0025] Such as figure 1 As shown, the core of the present invention includes an alarm module 1, a control module 2, and an alarm module 4. The control module 2 adopts single-chip microcomputer AT89S52 chip, and the crystal oscillation frequency of 6MHZ is used as the main frequency of the system. The temperature sensor 6 of the alarm module 1 adopts DS18B20, which can directly convert the collected environmental information into a digital signal and transmit it to the control module 2. The smoke sensor 7 of the alarm module 1 adopts an MQ-2 gas sensor, which converts the collected environmental information The information generates electrical signals, which are ampli...

Abstract

The invention discloses an automatic fire alarm system which comprises a control module, a sensor module and an alarm module. A single chip microcomputer is used as a core of the control module, the sensor module is connected with the control module and includes a temperature sensor and a smoke sensor, and the alarm module is connected with the control module and can achieve real-time alarming. The temperature sensor of the sensor module directly generates digital signals to be transmitted to the control module, and the smoke sensor generates electrical signals which are converted into digital signals through an amplification circuit and an analog-digital conversion circuit to be transmitted to the control module. The control module conducts data processing on the received digital signals, and is in control communication with the alarm module. The alarm module comprises a sound and light alarm device which can make an alarm sound and emit light. The automatic fire alarm system further comprises a display module and a manual alarm module, the display module can display system states in real time, and the manual alarm module can achieve manual alarming when the system does not give out an alarm while fire dangers happen.

Description

technical field [0001] The invention relates to a fire alarm system and method, in particular to a fire alarm system with certain intelligence, capable of automatic detection and alarm. Background technique [0002] Fire is an everlasting topic. No matter in the past or now, various fire accidents happen from time to time. The loss of life and property caused by fire is not something we can bear at any time. In today's society where economy and technology are developing day by day, although our material living standards are constantly improving, various technological inventions have brought us more convenience. However, the popularization and application of various electrical appliances has also brought us more potential safety hazards, especially in terms of fires. Various fire hazards often occur due to improper application of electrical appliances. Today's cities are developing rapidly, with high-rise buildings and dense crowds. If a fire danger occurs, the consequences ...
