Description
Technical Field
The invention relates to the field of electronic technology and automobile safety, in particular to a safety reminding device for preventing infants from being left in an automobile based on a stable power supply.
Background
China is the country with the most population in the world, the total number of infants is the front, and infant monitoring is an important problem of family care continuously. With the development of industry, automobiles enter thousands of households, and the automobiles bring convenience and certain dangers to people. Every year, the infant is dead because the infant is placed in the car alone. In hot summer, the temperature in the automobile can quickly reach more than fifty degrees when the sun shines directly, and the infant placed in the automobile independently is easy to cause renal failure and death due to heatstroke. Some parents put the baby in the car alone, still leave the air conditioner in the car after stopping, but do not shut off the engine, and the engine idle at this moment, because burn is insufficient, often produce the waste gas that contains a large amount of carbon monoxide. Carbon monoxide exhausted by the engine can be gradually gathered in the vehicle, and in addition, the oxygen is consumed by breathing of people in the vehicle to exhaust the carbon dioxide, and after a long time, the oxygen in the vehicle is gradually reduced, passengers can unconsciously lose consciousness and lose lives when being poisoned by the carbon monoxide. In recent years, many carbon monoxide poisoning accidents have occurred in infants and children in the car. Because modern automobiles mostly require a silencing effect, the airtightness of the automobiles is better and better, but the gas in the automobiles is difficult to circulate. If the internal and external circulation of the vehicle is not started, when the infant is placed in the vehicle independently, carbon monoxide poisoning is more easily caused due to poor resistance of the infant.
The infant is not clear about the electric appliances in the car due to the fact that the infant moves too much, safety problems can possibly be caused when the infant is placed in the car alone, for example, for a car adopting keyless starting and an electronic hand brake, the infant is likely to be mistakenly placed on some electronic switches when the infant is in the car, and the safety problems are caused. Therefore, when the infant is placed in the car alone, the driver and the parents are reminded of the infant, so that the infant can take measures as soon as possible to avoid danger. Some young parents have difficulty actually putting a child in mind due to heavy work and social competition. They sometimes forget the infants in the car, and once the car is parked under the sun for insolation or the outside is very cold in winter, the temperature in the car will rapidly rise or rapidly fall, and the children are easy to dehydrate and die due to the fact that the children are weaker in heat resistance and cold resistance than adults and the crying and screaming phenomenon after the symptoms such as thirst and the like appear.
At present, as automobiles move into more and more families, convenience is brought to people, and meanwhile, a plurality of problems are brought. As in recent years, only news reports have been made of the death by suffocation of children who are forgotten in cars by adults. Therefore, it is very urgent to solve the problem, but some prior art solutions, including components such as a sound sensor, a respiration sensor, and a micro oxygen generator, can largely prevent children who are forgotten in the vehicle from suffocating and dying, but these systems are complicated, and if the micro oxygen generator fails, children still have the possibility of suffocating and dying.
The application number is 201420743487.8's infant car safety alarm, including human infrared sensor, temperature sensor, vibration sensor, carbon monoxide sensor, can send the loudspeaker of the infant cry, one set of emergent ventilation unit. The device can give an alarm when an infant is placed in the car independently and meets the temperature of over 35 ℃, also can give an alarm when the infant is in the car and the content of carbon monoxide exceeds 200ppm, and simultaneously starts the emergency ventilation system to reduce the concentration of the carbon monoxide in the car. Thereby ensuring the safety of the infants in the vehicle as much as possible. The device still has the problem that the driver can not be reminded of forgetting the infant in the car in time after the forgetting event happens.
How to solve the defects of the prior art becomes a great problem to be solved urgently in the field of electronic technology and automobile safety.
