Description

Automatic alarm method and system for preventing in-vehicle sleepiness

Technical Field

The invention relates to the technical field of automobile control, in particular to an automatic alarm method and system for preventing sleepiness in an automobile.

Background

With the popularization of home automobiles, there are many dangerous places while providing convenience of transportation. In recent years, accidents that children are trapped in the car frequently occur due to misoperation or forgetting of drivers, and the like, and the accidents can cause certain damage to the mind and body of the children, and even serious consequences can be caused due to untimely discovery. Similarly, more and more people will breed pets such as cats and dogs and use the pets as a part of family members, and the pets will be carried when driving out for business, traveling and the like, and the following problem that the pets are trapped in the vehicles is not inconstant. Because children and pets lack the ability of autonomous behavior, once the car is locked, self rescue or help seeking can not be carried out, so that the life safety of the children and the pets is threatened.

In view of the above, the present invention is particularly proposed.

Disclosure of Invention

The first purpose of the invention is to provide an automatic alarm method for preventing sleepiness in a car, which can automatically detect and judge whether a person or a pet is detained in the car, send confirmation information to a user and realize automatic alarm.

In order to achieve the purpose, the invention adopts the following technical scheme:

the invention provides an automatic alarm method for preventing trapping in a vehicle, which comprises the following steps:

s1, detecting the state in a car, and judging whether detained people or pets exist;

s2, when the staying personnel or pets are detected, a notice is sent to the user, and whether an alarm stage is started or not is judged according to a feedback instruction of the user;

and S3, monitoring the state in the vehicle when the feedback instruction is not received within the appointed time, and judging whether to enter an alarm stage according to the monitoring data.

The automatic detection can prevent accidents caused by misoperation, carelessness and the like of a driver, which are trapped in the vehicle; when the phenomenon of being trapped is judged, notification information is sent to a user firstly, the user waits for confirmation, so that the phenomena of short leaving, resting on a backseat, misjudgment and the like can be avoided, and unnecessary troubles caused by direct alarming are prevented; when the feedback information of the user is not received within the designated time, the alarm can be automatically sent out to protect the safety of personnel or pets.

Preferably, monitoring of the in-vehicle condition is initiated after no user feedback is received within 2 minutes.

Further, in the step S1, the step of detecting the in-vehicle state includes:

after the vehicle is shut down and parked, the weight of all seats is detected, when the weight of the seats is larger than 2kg, the seats are judged to have passengers, when the passengers in the driving positions are detected to leave the seats, and the passengers are still detected in other seats, the passengers or pets staying in the vehicle are judged.

Further, the weight of all seats is detected, when the passengers in the driving seats are detected to leave the seats and other seats still detect the passengers, whether the vehicle door is in a locked state or not is detected, and if the vehicle door is in the locked state, the condition that the detained people or pets exist in the vehicle is judged.

Further, when the passengers in the driving seat leave the seat, the passengers are still detected in other seats, and the vehicle door is in a locked state, whether the seats with the weight are detained people or pets is judged through infrared induction.

The distribution of passengers in the vehicle can be effectively and clearly known by detecting the weight on the seat, whether the passengers are living bodies or not can be distinguished through infrared induction, and the situations that the passengers can interfere with the judgment of the detained result by the sundries in the vehicle, and the doors of children or pets with small ages cannot be opened even though the doors of the children or the pets are not locked can be considered, and the three judgment modes can be preferably used according to actual situations.

Further, in the step S3, the step of monitoring the state in the vehicle includes:

monitoring the temperature and the volume in the vehicle, and judging whether the temperature and the volume exceed safe values;

and when the temperature or the volume in the vehicle exceeds a safety value, entering an alarm stage.

Considering that the notified person may ignore the short message of the notification, and the situation is not an emergency situation, the in-vehicle state is monitored first, instead of directly entering the alarm stage, so that the intelligent and humanized effects are achieved on the premise of effectively guaranteeing the safety of the trapped person.

Whether the environmental temperature in the vehicle causes discomfort or danger to the trapped person or not is judged by monitoring the temperature and the volume in the vehicle, and an alarm can be given in time to help the trapped person; meanwhile, the mental state of a trapped person can be judged, and when children or pets call for fear and panic, the volume in the car is too high, and an alarm can be given in time.

And further, when the vehicle enters the alarm stage, the vehicle gives an alarm sound and flickers light, and the vehicle window is lowered by a specified height.

The alarm sound and the light can warn surrounding people to attract the attention of the people, the window is lowered to ventilate and can ensure the safety of a trapped person, the temperature in the car can be reduced at high temperature so as to improve the survival rate of children or pets, and convenience is not provided for subsequent rescue.

Preferably, the window that will be stranded both sides descends 3cm, forms the convection current and improves ventilation effect, can not influence the security in the car simultaneously, avoids children or pet to climb out the window, perhaps children or pet are taken away from the window.

A second object of the present invention is to provide an automatic alarm system for preventing trapping in a vehicle, comprising:

a detection module: the system is used for detecting the state in the vehicle and judging whether detained people or pets exist;

a communication module: the system is used for sending a notice to a user when the presence of the detained personnel or pets is detected, and judging whether to enter an alarm stage according to a feedback instruction of the user;

a vehicle body control module: and the monitoring device is used for monitoring the state in the vehicle when the feedback instruction is not received within the specified time, and judging whether to enter an alarm stage according to the monitoring data.

A third object of the present invention is to provide a computer-readable storage medium, on which a computer program is stored, which program, when being executed by a processor, carries out the steps of the autoalarm method as of the first object.

A fourth object of the present invention is to provide a computer device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, the processor implementing the steps of the automatic alarm method according to the first object when executing the program.

In a word, the automatic alarm method and the automatic alarm system provided by the invention can judge whether a trapped person is in the vehicle or not by detecting the seat weight, the locking state of the vehicle door and infrared induction, inform a user to confirm at the first time, and manually cancel the alarm or select the alarm according to the actual condition; after the feedback of the user is not received within the designated time, the state in the vehicle can be automatically monitored, when the trapped person is threatened safely or needs to seek help, the alarm is automatically given out, the vehicle window is lowered, the safety of the trapped person is protected to the maximum extent, and simultaneously the device is more humanized and intelligent.

For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "if" as used herein may be interpreted as "at" \8230; "or" when 8230; \8230; "or" in response to a determination ", depending on the context.

The invention discloses an automatic alarm method for preventing sleepiness in a vehicle, which comprises the following steps:

s2, when the presence of detained people or pets is detected, a notification is sent to a user, and whether an alarm stage is started or not is judged according to a feedback instruction of the user;

Specifically, referring to fig. 1-2, the embodiment of the present invention automatically activates the alarm system to start detecting the in-vehicle status after the vehicle is shut down and parked. First, the seat weight sensor is activated, which is provided on each seat, enabling simultaneous weight detection for all seats. Preferably, when the weight on the seat is greater than 2kg, it is judged that an occupant is present on the seat.

Because the driver grasps the control right of the vehicle, when the driver is positioned in the vehicle, the risk of being trapped in the vehicle does not exist, firstly, the weight on the driving position is only detected, when the driver is detected to leave the vehicle, the driver starts to detect whether passengers exist on other seats, redundant operations can be effectively reduced, and if no other passengers exist, the situation that no persons or pets stay in the vehicle exist is shown, and the alarm system is automatically turned off.

If the driver leaves the vehicle and other seats still detect the weight, the door lock sensor is activated to detect whether the door is in a locked state, and if the door is unlocked, the door lock sensor continuously detects the door state. And if the car door is locked, activating the pyroelectric infrared sensor on the corresponding seat, and detecting whether vital signs exist on the seat with the weight.

It is worth mentioning that, because younger children and pets also lack the ability of opening the door even when the door is not locked, consequently can according to actual demand, leave the seat at the driver, when other seats still detected weight, directly activate and release infrared sensor, judge whether there is vital sign on the seat that exists weight.

If the pyroelectric infrared sensor does not detect vital signs, the weight on the seat is possibly from articles or misjudgment, and the alarm system is closed; and if the vital signs are detected, the step S2 is entered, the GSM wireless communication module is activated, and a short message notification is sent to the appointed notifier.

Considering that the driver only leaves for a short time, or is near the vehicle, or misjudges and the like, after receiving the feedback of manually cancelling the alarm by the notified person, the alarm system is closed, so that unnecessary alarm can be avoided, and the user experience and the intelligence level are improved.

The notified person can also send feedback that an alarm needs to be given immediately, and the alarm system enters an alarm stage. After entering the warning stage, the sound and light warning module is activated, the vehicle can give out a warning with the sound of a warning sound and the light of flashing to attract the attention of surrounding personnel, and meanwhile, the vehicle window control module can be activated to enable the vehicle window to descend by a specified height for ventilation. Preferably, the window convection ventilation of stranded personnel or pet both sides can be fallen down, the window on the driving position also can be fallen down provides convenience for follow-up rescue. Preferably, the height that the door window descends is 3cm, can effectively reduce the interior temperature of car, improves children or pet's survival rate and waits for the rescue, also can not exert an influence to the security in the car, can effectively avoid children or pet to climb out the door window, or children or pet are taken away from the door window.

When the feedback response of the notified person is not received within 2 minutes, the alarm system starts to monitor the state in the car to avoid the danger of the person or the pet in the car, namely, the step S3 is entered. And at the moment, the temperature sensor and the sound sensor in the vehicle are simultaneously activated, whether the temperature and the sound in the vehicle exceed the safety values or not is monitored in real time, and if the temperature or the sound exceeds the safety values, the alarm system enters the same alarm stage.

Considering that the notified person may ignore the short message of the notification, for the purpose of protecting life safety, the in-vehicle state is monitored, instead of directly entering the alarm stage, and the alarm stage is entered when the temperature is too high and there is a potential safety risk, or when the volume of calling for help is too high due to shouting. The automatic alarm method can ensure the safety of the trapped person more intelligently and more humanizedly.

The system mainly comprises the three modules, and the aim of simultaneously mounting the same file system and realizing parallel operation can be well fulfilled by building the system.

In specific implementation, the above modules may be implemented as independent entities, or may be combined arbitrarily, and implemented as the same or several entities, and specific implementations of the above units may refer to the foregoing method embodiment, which is not described herein again.
