Abstract

The invention relates to a real-time detection protection system for preventing anoxia and heatstroke inside an automobile. The real-time detection protection system comprises a temperature, an oxygen sensor and a carbon dioxide sensor which are installed inside the automobile and used for detecting the temperature, the oxygen content and the carbon dioxide content inside the automobile respectively. Signals of the three sensors are connected with a signal conversion circuit. The signal conversion circuit is connected with a single chip microcomputer control circuit. The single chip microcomputer control circuit is connected with a relay driving circuit. The signals of the three sensors pass the signal conversion circuit and then enter the single chip microcomputer control circuit. The single chip microcomputer control circuit drives the relay driving circuit according to the set logic, and controls an automobile air-conditioner circuit to be closed and opened. A power circuit supplies power to circuits of the system. The real-time detection protection system can be used for preventing anoxia and heatstroke and provide real-time detection and safety protection of each automobile for preventing anoxia and heatstroke.

Description

technical field [0001] The invention relates to the field of signal detection, in particular to a real-time detection and protection system for preventing hypoxia and heatstroke in a vehicle, which can be applied to the real-time detection and protection for preventing hypoxia and heatstroke in a vehicle. Background technique [0002] Cars are the most frequently used means of transportation in modern times. People spend a lot of time in cars every day. The environmental quality in cars directly affects people's health. With the popularization of private cars, due to the lack of anti-hypoxia and temperature monitoring equipment, a series of problems have arisen in the actual use of cars. For example, when parents go shopping in the mall, children are often left alone in the car. When the weather is hot and the doors and windows are closed, the temperature in the car soars rapidly. According to scientific data, in an overheated car, it takes only 15 minutes. It can damage th...
