Description

Heatstroke prevention system for children detained in car

Technical Field

The utility model relates to a heatstroke prevention system especially relates to a children heatstroke prevention system is detained in car.

Background

When many parents drive to go out, the parents often get off the car temporarily for work, but leave or lock the young children in the car, and even forget the children to get on the car afterwards. In summer, high temperature is enough to cause heatstroke and even death of children in the car within dozens of minutes. This tragedy is common. According to the recent report of the journal of the United states today, the National Highway Traffic Safety Administration (NHTSA) of the United states indicates that heatstroke in the vehicle is the first leading cause of death in non-impact accidents in the United states for children 14 years old and younger. This tragedy is also frequent today where private cars have become popular in our country.

In addition to the need for parents to be alert, tragedies can be reduced by installing necessary equipment in the vehicle. At present, the main technical means are two types: opening the vehicle window or the vehicle door to cool the interior of the vehicle; and installing a wireless help-seeking system, and sending help-seeking information to parents to enable the parents to timely call for help. These two measures do reduce the occurrence of tragedies. The following major problems still remain: if the car key is taken away by the parents and the electric appliances in the car cannot supply power, the door and the window of the car cannot be opened; moreover, if the car is a young child, the car door window is opened to prevent heatstroke, the danger of being taken away and being taken away by people and peddled by the car is brought to the child in the car, the wireless help-seeking system is installed to send help-seeking information to the mobile phone of the parent, and if the parent cannot catch up without seeing the help-seeking information, the child in the car still cannot be rescued in time. Therefore, how to effectively prevent children staying in the car from heatstroke and ensure the safety of the children becomes a great hot problem in the field.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a safe effectual car is detained children's prevention system of heatstroke.

The technical scheme is as follows: the utility model discloses a children heatstroke prevention system is detained in car connects and controls vehicle air conditioning system, heatstroke prevention system includes control module to and the power drive module who links to each other with control module in the car detection module and drive vehicle air conditioning system respectively, detection module includes temperature sensor, human inductive pick-up and car key detector in the car, power drive module includes special air conditioner internal-combustion engine, generator and one-way clutch.

Preferably, control module links to each other with the storage battery, and the storage battery is the control module power supply, even when the car key was extracted, circuit interruption in the car, control module still can normally work.

Preferably, the control module is an MC9S12 series controller.

Preferably, the temperature sensor is a DS18B20 temperature sensor.

Preferably, the human body induction sensor is an RE200B sensor.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is as follows showing: (1) after the automobile is flamed out, the special air-conditioning internal combustion engine drives the air-conditioning system to cool the interior of the automobile, thereby preventing children or adults from suffering from heatstroke; (2) through three steps of detection links of a human body, temperature and a car key, the system is ensured to be started when the engine does not work, the temperature in the car is too high, and people move, so that unnecessary loss caused by mistaken starting of the system is prevented.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses a detain children's heatstroke prevention system in car connects and controls vehicle air conditioning system, and heatstroke prevention system includes detection module and power drive module in control module, the car, detection module includes temperature sensor, human body induction sensor and car key detector in the car, power drive module includes special air conditioner internal-combustion engine, generator and one-way clutch. The special air-conditioning internal combustion engine and the generator do not provide power for other equipment on the vehicle, the special air-conditioning internal combustion engine pumps oil from an automobile oil tank, and waste gas of the special air-conditioning internal combustion engine enters an engine exhaust pipe. The one-way clutch is used between the special air-conditioning internal combustion engine and the air-conditioning compressor, and has the functions of one-way engagement and reverse disengagement. When the internal combustion engine special for the air conditioner works, the compressor is driven to rotate through the one-way clutch. After the engine is started, the special internal combustion engine for the air conditioner is separated from the rotation of the air conditioner compressor, so that the special internal combustion engine for the air conditioner is protected from being damaged. Meanwhile, the control unit stops the work of the internal combustion engine special for the air conditioner and connects the air conditioner compressor with the automobile engine.

The control module is connected with an independent storage battery, the storage battery supplies power to the control module, and even when a car key is pulled out, a circuit in the car is interrupted, and the control module can still normally work.

Specifically, the control module is an MC9S12 series controller, is a single chip microcomputer series based on a faster CPU12 core, has an on-chip error correction capability, is compatible with 68HC11 and 68HC12 structure codes, and is convenient to transplant.

Specifically, the temperature sensor is a DS18B20 temperature sensor, digital signals are output by the temperature sensor, and the temperature sensor has the characteristics of small volume, low hardware overhead, strong anti-interference capability and high precision, and the DS18B20 digital temperature sensor is convenient to wire and can be applied to various occasions after being packaged, such as a pipeline type, a thread type, a magnet adsorption type, a stainless steel packaging type, various types, LTM8877, LTM8874 and the like.

Specifically, the human body induction sensor is an RE200B sensor. RE200B detects infrared radiation by adopting the characteristic that the polarization of pyroelectric materials changes along with temperature, and inhibits the interference generated by temperature change by matching with a double-sensitive element complementary method, and the working stability is high.

The working process of the utility model is as follows:

firstly, detecting whether a person moves in the vehicle through a human body induction sensor, secondly, judging the temperature in the vehicle through a temperature sensor arranged in the vehicle, and further, judging whether a vehicle key is inserted; if the dangerous condition that a person is in the vehicle and the temperature in the vehicle is too high is detected, and the vehicle key is not inserted, the special air-conditioning internal combustion engine is started through the control module to drive the air-conditioning system to work, so that the temperature in the vehicle is reduced. The system for preventing heatstroke in the vehicle cools the interior of the vehicle by equipping the vehicle with a special air-conditioning internal combustion engine and a detection control system, and can well protect people in the vehicle from heatstroke.
