Smoke sensing alarm system based on GSM short message technology and operation method thereof

Abstract

The invention discloses a smoke sensing alarm system based on GSM short message technology and an operation method thereof. The smoke sensing alarm system and the operation method belong to the technical field of automotive instruments. The smoke sensing alarm system comprises the components of a smoke sensor, a single-chip microcomputer module, a state display module, a buzzer alarm module, a GSM communication module and a power supply. The smoke sensor is used for detecting the smoke concentration in an automobile. The smoke sensor is connected with the single-chip microcomputer module. The state display module is connected with the single-chip microcomputer module and is used for displaying the data processing result of the single-chip microcomputer module. The buzzer alarm module is mounted in the automobile and is connected with the single-chip microcomputer module and generates an audio alarm according to the output instruction of the single-chip microcomputer module. The GSM communication module is connected with the single-chip microcomputer module and is used for transmitting an alarm signal to a contact person. The smoke sensing alarm system settles problems of in-automobile person injury by an overhigh gas concentration in the automobile and incapability of finding in time. The smoke sensing alarm system has advantages of detecting the gas concentration in the automobile in real time, generating an alarm signal when the gas concentration exceeds a safe range, and transmitting alarm information to the mobile phones of an automobile owner and a preset contact person.

Description

technical field [0001] The invention belongs to the field of automotive instrumentation, relates to the direction of remote communication, and in particular relates to a smoke sensing alarm system based on GSM short message technology and an operating method thereof. Background technique [0002] With the development of wireless technology, wireless communication is more and more widely used in residents' life. At the same time, due to the wide range of mobile phone module communication and the sharp drop in its cost, it also plays an increasingly important role in life. GSM system is currently the most mature mobile communication system in my country. Residents live in hot weather. Many people have the habit of parking and turning on the air conditioner, and taking a nap in the car. Little do they know that this can easily lead to death from carbon monoxide poisoning. Because the air conditioner is turned on for a long time, the engine is idling, and the gasoline is not c...
