Automatic car alarm based on in-car temperature and gas detection

Abstract

The invention provides an automatic car alarm based on in-car temperature and gas detection. The automatic car alarm based on in-car temperature and gas detection comprises a housing and a host in the housing. The host comprises a central processing unit, and further comprises a storage, an in-car gas environment measuring module, a communication and alarm module, a data input module, a GPS locating module, an infrared induction module, a power supply module and a storage battery which are connected with the central processing unit. The infrared induction module inducts whether a person stays inside a car or not, and transmits induction data to the central processing unit. The central processing unit analyzes whether the in-car gas environment measuring module is opened or not according to the data. The in-car gas environment measuring module detects parameters of O2, CO, CO2 and temperature in the car. The central processing unit enables the parameters detected by the in-car gas environment measuring module to be compared with alarm situation parameters prestored in the storage, and the alarm situation is controlled to be fed back to a car owner based on the comparison result. By the automatic car alarm based on in-car temperature and gas detection, based on the condition whether a person stays inside the car or not, the parameters of O2, CO, CO2 and temperature in the car are detected automatically, and an alarm is given automatically when a person feels uncomfortable.

Description

technical field [0001] The invention relates to the field of automobile safety detection, in particular to an instrument capable of automatically detecting parameters of O2, CO, CO2 and temperature in a car and automatically warning in various human discomfort situations. Background technique [0002] In recent years, with the continuous growth of the middle class, the number of cars in my country, especially private cars, has grown rapidly year by year. The safety of the car interior has also been paid more and more attention by car buyers. The news of CO poisoning death caused by driving the air conditioner in the car is often reported in the newspapers. With the occurrence of many school bus suffocation deaths, the gas environment in the car become an increasingly serious problem. After investigation, O 2 , CO, CO 2 Gas and temperature are an important part of the safety of the gas environment in the car, and are also key factors leading to suffocation in the car. [...

AI Technical Summary

Problems solved by technology

[0004] 1. Directly open the sunroof: When people in the car are sleeping or no one is in the car, it is inconvenient and unsafe to directly open the sunroof. cause property or personal damage;

[0005] 2. Only consider oxygen to cause suffocation, but in fact, there are many factors that cause suffocation in the car, the most important are CO, CO 2 The three influencing factors of temperature and temperature, the influence of CO is especially common when the air conditioner is turned on in the car to sleep and suffocation.

[0006] 3. Existing instruments operate only when oxygen levels are detected to be lethal, and when O 2 , CO, CO 2 When the four parameters of temperature and temperature do not reach the fatal level but affect the driver's thinking and operation, there is no warning to the driver. When the driver drives the vehicle in this situation, it is easy to make a misjudgment, which increases the safety hazard;

[0007] 4. In the existing technology, when an emergency occurs, the car owner is not notified in time: the car owner is usually in the car or not far away from the car. If the car owner can be notified in time, it is convenient and quick for the car owner to come back to solve the police situation, and he can quickly understand what happened in your car
