Technical Field

The invention relates to an oxygen detection device, in particular to an oxygen detection alarm device in an automobile, and belongs to the technical field of vehicle-mounted safety prevention and control.

Background

In recent years, with the increasing popularity of automobiles, accidents in automobiles often occur, and most of the accidents occur in private cars and cars. When people leave the automobile and lock the automobile door tightly, due to the fact that the space in the automobile is narrow and small, outside air is difficult to enter the automobile, weak groups such as children, old people and disabled people are confined in the automobile, adverse reactions such as heartbeat acceleration and blood pressure rise can occur due to oxygen deficiency in a short time, coma can occur after long-time stay, and life can be threatened after long-time stay. The death accident occurs and the remorseness is realized. It would be desirable to provide a device that automatically alarms when the oxygen level in the vehicle is low to reduce the incidence of suffocation death in the vehicle.

Disclosure of Invention

The invention aims to provide an oxygen detection alarm device in an automobile, which is used for detecting the oxygen content in the automobile and sending alarm information when the oxygen content is less.

The invention adopts the following specific technical scheme:

the utility model provides an oxygen detection alarm device in car which characterized by: the device comprises a single chip microcomputer module, a voltage reduction module, an oxygen detection module, an analog-to-digital conversion module, a key module, a GSM module, a liquid crystal display module, a CAN bus transceiving module and an alarm module, wherein the voltage reduction module, the analog-to-digital conversion module, the key module, the GSM module, the liquid crystal display module, the CAN bus transceiving module and the alarm module are respectively connected with the single chip microcomputer module, and the oxygen detection module is connected with the analog-to-digital conversion module.

The device has 3 alarm modes that a GSM module makes a call and sends a short message to a vehicle owner, a CAN bus transceiver module controls an automobile alarm to send an alarm signal and controls an alarm module to send the alarm signal.

The invention has the beneficial effects that: the invention realizes the real-time detection and display of the oxygen concentration in the automobile, and when the concentration is lower than the set value, the GSM module calls to send a short message to inform the automobile owner, the CAN bus transceiver module controls the automobile alarm to send out an alarm signal, and the alarm module controls the alarm module to send out an alarm signal. The device is used for detecting oxygen in the automobile, and effectively prevents children, old people, disabled people and the like from death due to oxygen deficiency when staying in the automobile for a long time.
