Meanwhile display screen is set on the compartment lateral wall of school bus, the signal output end connection display driving electricity of microcontroller
Road, display driver circuit drive the work of display screen.As someone in school bus, microcontroller outputs signals to display driving electricity
Road, display driver circuit drive display screen, so that the printed words of " interior someone " are shown on a display screen, so that surrounding
Personnel succour to personnel are lost in school bus.
School bus alarm method is lost by the child that above system carries out, the method in turn includes the following steps：
（1）Whether vehicle interior temperature is judged more than 28 DEG C, is for example to carry out step（2）, for example otherwise repeat step（1）；
The temperature information of collected car is transferred to microcontroller by temperature sensor, and microcontroller judges according to the information received
Whether interior temperature if more than then carries out step more than 28 DEG C（2）If be not above, car is temporarily safety
, it is only necessary to vehicle interior temperature information is detected at any time.
（2）Judge it is interior whether someone, be for example to carry out step（3）, for example no return step（1）；Infrared array temperature
Degree sensor detects the temperature information of different zones in its detection range, when some region is higher than vehicle interior temperature, then shows vehicle
Interior someone will do it step if interior someone（3）.If detecting interior nobody at this time, show to be temporarily safety
, return step（1）?.
（3）Obtain vehicle position information.GPS module acquires the information of vehicle position, and collected information is passed
Defeated to be stored to microcontroller, the rescue that this step loses personnel for car has great significance.
（4）Judge whether vehicle interior temperature is higher than 30 DEG C, be for example, carries out step（5）, for example otherwise return step（4）；
Temperature sensor continues working, and collected temperature information is transferred to microcontroller, microcontroller believes the temperature received
Breath is compared with 30 DEG C, when finding that vehicle interior temperature is more than 30 DEG C, is illustrated that occupant faces to threatening, is walked at this time
Suddenly（5）, when being not above 30 DEG C such as vehicle interior temperature, it is safe for illustrating occupant temporarily, it is only necessary to be carried out to vehicle interior temperature
Lasting monitoring.
（5）Warning message is sent to client, warning message includes step（3）The location information of the vehicle got.When
Vehicle interior temperature is more than after 30 DEG C, and it can include vehicle in warning message that microcontroller, which sends warning message to client by gsm module,
Location information, to guarantee that occupant can be by quick rescue.
Step（5）In every 5s to client send a warning message pass through the side of INFORMATION BOMB under emergency situation
Formula guarantees the problem of information can be read into, prevent information from passing into silence.
Step（5）After the middle transmission warning message to client, client judges whether warning message is read, for example
It is no, then：
Firstly, client reads the warning message of agreement format；
Then, client enters sound and vibration alarming interface, there is " eliminating alarm " and " vehicle location " in alert interface
Two buttons and word alarm information, word alarm information alert " child is dangerous, please take immediate steps "；
Finally, whether button is clicked for judgement " eliminating alarm ", it is for example to stop sound and vibration alarming；
Whether judgement " vehicle location " button is clicked, and is for example that electronic map interface is shown in client, electronically
The specific location of figure interface display school bus.In this way, guarantee that warning message can be read by related personnel, guarantee vehicle
Inside lose the safety of personnel.
（6）Judge whether vehicle interior temperature is higher than 35 DEG C, be for example, carries out step（7）, for example otherwise repeat step（6）；
Temperature sensor continues working, and collected temperature information is transferred to microcontroller, microcontroller believes the temperature received
Breath is compared with 35 DEG C, when finding that vehicle interior temperature is more than 35 DEG C, is illustrated that occupant is very critical, is carried out step at this time（7）,
Implement the rescue to occupant.When being not above 35 DEG C such as vehicle interior temperature, illustrate that interior situation does not reach especially critical
Stage, it is only necessary to lasting monitoring is carried out to vehicle interior temperature.
（7）Car door opening plays voice messaging and occupant is urged to get off, while sending mentioning for car door opening to client
Show information.Microcontroller outputs signals to the second relay drive circuit, and the second relay drive circuit drives the second relay
Normally opened contact obtain electric so that the normally opened contact of the second relay is closed, be switched on the power circuit of car door,
Car door opening.Microcontroller outputs signals to the first relay drive circuit, and the first relay drive circuit drives the first relay
The normally opened contact of device obtains electric, so that the normally opened contact of the first relay is closed, obtains voice module electric, issues language
Sound prompt tone prompts occupant to get off in time.
By above step, guarantee the safety of occupant, in the condition of high temperature after avoiding occupant from being lost in car
It is lower the threat of life occur.
In order to further ensure the safety of occupant, step（3）Later, need to judge that the temperature in school bus increases
Gesture, the temperature growth trend in school bus determine that method is：
First：In 30s, primary interior temperature information is obtained every 1s, then shares 29 periods, 29 can be obtained
A temperature data, obtaining data isT n （n=1~29）,T n It isnThe temperature information in vehicle that a period gets；
Then：Pass through formula（1）Obtain school vehicle interior temperature initially with final jitter values；
；（Formula 1）
∆TFor school vehicle interior temperature initially with final jitter values；T 29For the temperature value in the 29th period school bus,T 1For
Temperature value in 1st period school bus；
Then：It is prepared by the following the variation tendency of school vehicle interior temperature；
∆T bx =T m+1 -T m ；（m=1~28）
∆T bx =（∆T b1 、∆T b2 、∆T b3 、...、∆T b27 ）
T m+1It ism+1Temperature in period school bus；T m It ismTemperature in period school bus；
∆T bx For temperature gap ordered series of numbers；
∆T b1 For the temperature gap in the 2nd period and the 1st period school bus；∆T b2 For the 3rd period and
Temperature gap in 2nd period school bus；∆T b3 For the temperature gap in the 4th period and the 3rd period school bus；
∆T b27 For the temperature gap in the 28th period and the 27th period school bus；
JudgementT bx Last 5 numbers of ordered series of numbers are greater than equal to 1；
It is rightT bx Size comparison is carried out, maximum value is denoted asT max , judgementT max Whether last of ordered series of numbers is located at
Position；
Finally：Step is directly entered when meeting following 3 conditions（7）, otherwise carry out step（4）, condition（1）：School bus
Interior temperature initially with final jitter valuesTWhen more than 1 DEG C/15s；Condition（2）：∆T bx Last 5 numbers of ordered series of numbers are more than or equal to
1；Condition（3）：∆T max Positioned at last position of ordered series of numbers.
More than satisfaction when 3 conditions, illustrate that interior temperature is increasing sharply, it can if successively followed the steps below again
Optimal rescue period can be missed, then can directly carry out step at this time（7）By car door opening, the battalion of occupant is carried out
It rescues, to reduce the high temperature risk that occupant is likely encountered.When above 3 conditions are any to be unsatisfactory for, illustrate vehicle interior temperature
Growth rate is not that quickly, can follow the steps below.It on the one hand ensure that the safety of occupant by this method, it is another
Aspect also protects the safety of school bus.
Method described in the utility model is it is possible to prevente effectively from child is lost in the danger caused in school bus, guarantee child's peace
Entirely, there is preferable social benefit.
