Description

Technical Field

[0001] The present invention relates to the technical field of vehicle safety, and in particular to an intelligent anti-suffocation remote alarm system in a vehicle. Background Art

[0002] Generally speaking, with the rapid development of my country's automobile industry and the improvement of people's living standards, the number of cars owned by residents has also increased rapidly. However, while my country's automobile industry is developing rapidly, the potential safety hazards brought by automobiles cannot be ignored. In daily life, passengers may cause accidents such as carbon monoxide poisoning or suffocation due to lack of oxygen due to momentary negligence.

[0003] The existing anti-suffocation technology for in-vehicle personnel is mainly based on a set of local safety systems composed of modules such as thermal sensors, air sensors, personnel status sensors, temperature sensors, oxygen sensors, and carbon dioxide sensors. The main problems are:

[0004] 1. Remote alarm is not possible, and reminders can only be given at the location of the device. If the owner is not at home, the alarm signal cannot be received, which may cause suffocation in the car;

[0005] 2. Over-reliance on the in-vehicle system, which makes it unable to continue working when the vehicle breaks down.

[0006] Therefore, it is necessary to provide an in-vehicle intelligent anti-suffocation remote alarm system to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0034] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0035] First embodiment:

[0036] Please refer to Figure 1 and Figure 2 ,in, Figure 1 A flow chart of a first embodiment of the in-vehicle intelligent anti-suffocation remote alarm system provided by the present invention; Figure 2 A physical picture of the in-vehicle intelligent anti-suffocation remote alarm system provided by the present invention. An in-vehicle intelligent anti-suffocation remote alarm system comprises the following steps:

[0037] The S1 master initializes the carbon dioxide sensor module through data communication and sets the initialization time to 10 seconds;

[0038] The S2 main control module initializes the data processing of the LCD display, DHT11 temperature and humidity sensor, infrared thermal release, and SIM800C module by sending data. After the initialization of each module is completed, the LCD screen will light up to display the temperature, humidity, carbon dioxide concentration, and whether there is someone, and then proceed to the next step;

[0039] The S3 main control determines whether the key is pressed through the data transmitted by the external key. If it is pressed, the screen will enter the low power consumption mode. Preferably, it will enter step S4 regardless of whether it is pressed or not.

[0040] S4 is better, at this time, each module measures the indicators at all times and transmits the data to the main control in real time for data processing and conversion into various indicators that can be recognized by the main control;

[0041] The S5 master control compares the various indicators obtained from S4 with the temperature threshold, carbon dioxide concentration threshold, and humidity threshold, and can be observed in real time on the LCD. The system will automatically determine whether the alarm conditions are met;

[0042] S6: When the module detects that there is someone in the car and the temperature in the car reaches the temperature threshold, the humidity reaches the humidity threshold, and the carbon dioxide concentration reaches the concentration threshold, the system alarm mechanism will be triggered and the process will proceed to step S7. If the alarm is not triggered, the process will return to step S3.

[0043] The S7 master control will change the LCD screen background to red and sound a buzzer alarm. The master control will control the SIM800C module and send GPS location information and alarm SMS to the user in a timely manner. It will then determine whether the SMS is sent successfully. If successful, it will enter S8. If unsuccessful, it will enter S7 again.

[0044] In S8, each module continues to detect whether it is still in the alarm environment. The main control makes a real-time judgment. If the alarm condition is still met, the detection continues. At this time, the buzzer is always working. If the alarm condition is no longer met, it returns to step S3 and the buzzer is turned off.

[0045] In step S1, the main control controls the carbon dioxide module by controlling the high and low level changes of the pins through the program burned into the chip to realize the initialization of the carbon dioxide concentration module, and the waiting time for the module to stabilize is set to 10s.

[0046] In step S2, the master controller also initializes each module through high and low levels. After the initialization is completed, the LCD screen will use a white background to display the temperature, humidity, carbon dioxide concentration, and two status information "ALIVE" and "NO ALIVE" to determine whether there is someone.

[0047] In step S3, the key Figure 2 As shown in the low power button, pressing it will enter the low power mode. At this time, the main control will control the LCD power to turn off, so that the LCD screen remains in the off state.

[0048] In steps S4, S5 and S6, the detection data in the module will eventually be sent to the main control through the circuit. The main control will process and calculate the data, and finally obtain the required indicators and compare them with the upper alarm thresholds. If the temperature is greater than 35°C, the carbon dioxide concentration is greater than 2000ppm, the relative humidity reaches 61% and above, and someone is detected in the current environment, the alarm condition will be triggered. If the alarm condition is not triggered, it will return to S3, and in a normal car environment, it will cycle back to S3 for a long time, and then repeat the detection and judgment.

[0049] In step S7, after the alarm condition is triggered, the main control will convert the system to an alarm state. First, the LCD background color will be set to red. Second, the buzzer will sound an alarm. Finally, the main control controls the SIM800C module to send the edited text message to the emergency contact, which includes the text "Warning! Suffocation alarm occurs in the car, please return to the car in time for first aid!" and the positioning information obtained by the SIM800C module at this time. If the message is sent successfully, proceed to S8; if it is not sent successfully, try to send it repeatedly until the alarm message is sent successfully.

[0050] In step S8, after sending the text message, the system will continue to detect various indicators of the surrounding environment to determine whether the alarm conditions are still met. If they are still met, S8 will be repeated; if the alarm conditions are no longer met, it will return to S3 and perform the next detection cycle. Preferably, if the alarm environment is not exited, the text message will not be sent repeatedly, and a remote text message alarm will only be performed after entering a new alarm state.

[0051] The sensor determines whether suffocation has occurred and issues a remote alarm for the current status in the vehicle through the communication module, thereby preventing suffocation in the vehicle. This overcomes the shortcomings of the vehicle anti-suffocation technology, such as high cost, inability to issue a remote alarm, and over-reliance on the vehicle system.

[0052] According to the processing results of the in-vehicle sensor device, signals are sent to the controller in real time, including temperature, humidity signals, carbon dioxide signals and infrared signals, and the four signals are continuously calculated to see if they exceed the threshold. When the signal value exceeds the threshold, the alarm device immediately alarms and sends an alarm message to the emergency contact.

[0053] The above thresholds are preset for temperature, humidity, CO 2 Concentration value, the above temperature value preset threshold is 30℃, humidity is 61% relative humidity, CO 2 The concentration is 2000ppm.

[0054] Compared with the related art, the in-vehicle intelligent anti-suffocation remote alarm system provided by the present invention has the following beneficial effects:

[0055] By using sensors to determine when suffocation conditions have been reached and through the communication module, a remote alarm is issued for the current status in the car, thereby preventing suffocation of people in the car. The defects of high cost of anti-suffocation technology in the car, inability to provide remote alarms, and over-reliance on the in-car system are overcome. According to the processing results of the in-car sensor device, signals are sent to the controller in real time, including temperature, humidity signals, carbon dioxide signals and infrared signals, and the four signals are continuously calculated to see if they exceed the threshold. When the signal value exceeds the threshold, the alarm device immediately sounds an alarm and sends an alarm message to the emergency contact, thereby enhancing the safety of rest in the car and avoiding accidents in the car.

[0056] The present invention further provides a sensor-based in-vehicle anti-suffocation method, the method comprising the following steps:

[0057] Determine whether there is a person in the vehicle according to the infrared sensor, and when the determination result is yes, send a signal to the vehicle body controller in real time and continuously to indicate that the person in the vehicle is in a resting state or lying state;

[0058] After receiving the signal indicating that the occupant is in a resting state or lying state, the body controller determines whether the carbon dioxide concentration is in an excessive state according to the detection result of the carbon dioxide sensor;

[0059] When the infrared sensor determines that the carbon dioxide concentration is in an excessive state, the body controller determines whether the vehicle is in a parking state or the vehicle speed is zero according to the vehicle speed sensor;

[0060] When the body controller determines that the vehicle is in a parking state or the vehicle speed is zero, it determines whether the vehicle air conditioner is in an on state according to the state signal of the vehicle air conditioner;

[0061] When the body controller determines that the vehicle's air conditioner is in the on state, it calculates the cumulative time of continuously receiving signals indicating that the occupant is in a resting or lying state. When the cumulative time reaches or exceeds the threshold time, the window is controlled to open to a preset state.

[0062] The temperature sensor, humidity sensor and carbon dioxide concentration sensor in the above sensors are three sensors installed on the roof of the vehicle respectively. In addition, the infrared sensor is installed inside the vehicle, located at the center of the junction between the front window and the driving platform of the vehicle, or at the junction between the rear window glass and the seat, or at the junction between the door and the window.
