[0036] It should be noted that the following detailed description is merely exemplary and is intended to provide further description of the present application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs.

[0037] It should be noted that the terms used herein are merely for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

[0038] The embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0039] Please refer to Figure 1 As shown in the drawings, the present application provides an intelligent protection system for passenger car safety, which is used for intelligent protection of power supply equipment and power consumption equipment in a passenger car. The power supply equipment usually refers to a power supply battery, and the power consumption equipment refers to equipment that needs power in the passenger car. By monitoring the driver and the members in the passenger cabin and based on the comprehensive analysis of the running state of the vehicle and the power consumption and power storage state, the intelligent protection of power consumption can be started in time to prevent the problem of power supply equipment power loss in the passenger car.

[0040] Specifically, the intelligent protection system includes a personnel detection module, a power consumption detection module, a passenger car master control data acquisition module, a power consumption analysis module, and an intelligent protection module.

[0041] The personnel detection module includes a driver seat detection unit and a passenger cabin detection unit. The driver seat detection unit is used for detecting the personnel at the driver seat. The driver seat detection unit includes a face recognition camera and a weighing sensor. The face recognition camera is arranged on the side of the driver seat close to the forward direction of the passenger car, and the weighing sensor is arranged at the bottom of the driver seat. The driver seat detection unit is configured with a driver seat detection strategy, which includes the following steps:

[0042] Step S1011, the load weight of the driver seat is obtained by the weighing sensor. When the load weight is less than a first load threshold, a driver seat vacancy signal is output.

[0043] Step S1012, when the load weight is greater than or equal to the first load threshold and less than the second load threshold, obtaining a driving position recognition image through the face recognition camera;

[0044] Step S1013, when the load weight is greater than or equal to the second load threshold, obtaining a driving position recognition image every interval of the first recognition time length.

[0045] The passenger cabin detection unit is used for detecting the number of personnel in the passenger cabin. The passenger cabin detection unit comprises a radar detector. The radar detector of the present application is specifically a radar life detector, which is a life detection device integrating radar technology and biomedical engineering technology. It is mainly made by using the reflection principle of electromagnetic waves. By detecting various micro-movements caused by human life activities, information about breathing and heartbeat is obtained from these micro-movements, so as to identify whether there is life. The radar life detector is the most advanced life detector in the world. Its active detection mode makes it less affected by factors such as temperature, humidity, noise and site terrain. The continuous emission mechanism of electromagnetic signals further increases its regional detection function. Since a passenger car usually carries a large number of personnel, for example, a bus usually carries 50 passengers, it is necessary to set up a radar detector. If there are passengers resting in the passenger cabin, the electrical equipment, especially the air conditioner, needs to be kept on to maintain sufficient oxygen in the passenger cabin. Therefore, while carrying out electrical safety protection, the comfort of passengers needs to be ensured. The radar detector is arranged on one side of the top of the passenger cabin. The passenger cabin detection unit is configured with a passenger cabin detection strategy. The passenger cabin detection strategy comprises the following steps:

[0046] Step S1021, after receiving the driving position vacancy signal, obtaining vital sign information through the radar detector and outputting the vital sign information, wherein the vital sign information comprises passenger cabin personnel and passenger cabin personnel.

[0047] The power detection module is used for detecting the power consumption data and power supply data of the passenger car. The power consumption data comprises the power consumption of the electrical equipment, and the power supply data comprises the power storage capacity of the power supply equipment. The power detection module is configured with a power detection strategy. The power detection strategy comprises the following steps:

[0048] Step S201, when in a regular detection mode, detecting the power storage capacity of the power supply equipment and setting the power storage capacity in the regular detection mode as a regular power storage capacity. In the regular detection mode, the driver is in the vehicle and in a sober state at this time. At this time, only regular detection is needed. The driver will self-control the overall operation of the vehicle and the electrical safety, and in the regular detection mode, as long as the power required for starting the passenger car is left, the power supply equipment can be ensured not to be short of power;

[0049] Step S202, when in the first emergency detection mode, detecting the power storage amount of the power supply device, and setting the power storage amount in the first emergency detection mode as the first power storage amount; in the first emergency detection mode, there is no personnel in the passenger car, if the state of the power supply device of the passenger car is in the open state at this time, it will undoubtedly cause the power loss of the power supply device of the passenger car, and cause the power shortage;

[0050] Step S203, when in the second emergency detection mode and the engine is started, obtaining the oil remaining data and setting it as the second remaining oil amount; when in the second emergency detection mode and the engine is off, obtaining the power consumption of the power consumption device every first power consumption detection time interval and setting it as the second power consumption, obtaining the power storage amount of the power supply device and setting it as the second power storage amount; in the second emergency detection mode, there are passengers in the passenger compartment, so the basic power demand of the passengers needs to be guaranteed, for example, if the external environment temperature is too high or too low, at this time, the air conditioner in the passenger compartment is in the open state, if the engine is started, the power consumption safety is related to the remaining oil amount, if the remaining oil amount is sufficient, the power consumption device can be kept on, if the remaining oil amount reaches the limit, it needs to be closed; if the engine is off, the power consumption safety at this time is related to the relationship between the power consumption and the power storage amount, if the power consumption is too fast and the power storage amount reaches the limit, the power amount for starting the passenger car needs to be left, and the power supply device needs to be closed.

[0051] Step S204, when in the third emergency detection mode and the engine is started, obtaining the oil remaining data and setting it as the third remaining oil amount; when in the third emergency detection mode and the engine is off, obtaining the power consumption of the power consumption device every second power consumption detection time interval and setting it as the third power consumption, obtaining the power storage amount of the power supply device and setting it as the third power storage amount; in the third emergency detection mode, the driver is in the car, a specific case is that the driver is in the driving position and in the resting state, at this time, there will also be a problem that the driver does not supervise the power consumption in time, causing the power loss of the power supply device, therefore, the engine starting and engine off conditions are monitored by referring to the second emergency detection mode, however, in this state, two ladder power supply modes can be used, first, when the remaining oil amount is small, the engine can be closed, the power supply device is powered, if the power storage amount of the power supply device is also insufficient, the power-off treatment is performed, which guarantees the power safety of the passenger car, and also provides the basic power demand for the driver and the passengers.

[0052] The first power consumption detection time is less than the second power consumption detection time; the detection modes are sorted from the highest risk to the lowest risk in terms of power consumption safety, and the order of sorting is: the first emergency detection mode, the second emergency detection mode, the third emergency detection mode and the normal detection mode.

[0053] The passenger vehicle overall control data acquisition module is configured to acquire passenger vehicle basic operation data, including engine start state data and fuel remaining data; the engine start state data includes engine start and engine stop.

[0054] The power consumption analysis module is configured with a power consumption analysis strategy, including the following steps:

[0055] Step S301, analyzing the personnel detection data obtained by the personnel detection module, and dividing the detection mode according to the personnel detection data;

[0056] Step S302, analyzing the power consumption and power storage data and the passenger vehicle basic operation data based on different detection modes, and outputting corresponding protection data;

[0057] The power consumption analysis strategy further includes a power consumption detection division sub-strategy, which includes the following steps:

[0058] Step S3011, performing iris feature recognition on the driving seat recognition image, and outputting a driving seat personnel present signal when the iris feature is recognized; the method of iris feature recognition is as follows: collecting an iris image through an image collection system; positioning the iris, finding the iris in the collected image and marking the accurate position; then extracting the iris feature, extracting the texture feature code of the image after iris positioning, and calculating the feature value of the iris;

[0059] Step S3012, outputting a driving seat vacancy signal when the iris feature is not recognized, and the load weight is greater than or equal to a first load threshold and less than a second load threshold;

[0060] Step S3013, outputting a driving seat personnel fatigue signal when the iris feature is not recognized and the load weight is greater than or equal to the second load threshold;

[0061] Step S3014, starting a regular detection mode when the driving seat personnel present signal is received;

[0062] Step S3015, starting a first-level emergency detection mode when the driving seat vacancy signal is received and there is no personnel in the passenger cabin; starting a second-level emergency detection mode when the driving seat vacancy signal is received and there is personnel in the passenger cabin;

[0063] Step S3016, starting a third-level emergency detection mode when the driving seat personnel fatigue signal is received.

[0064] The power consumption analysis strategy further includes a power consumption safety analysis sub-strategy, which includes the following steps:

[0065] Step S3021, when the normal stored power is less than or equal to the first stored power threshold, output a normal power-off protection signal;

[0066] Step S3022, when the first-level stored power is less than or equal to the second stored power threshold, output a first-level power-off protection signal; the first stored power threshold is less than the second stored power threshold, because the risk level of the first emergency detection mode is obviously higher than that of the normal detection mode, so the first emergency detection mode can perform power-off protection when the stored power of the power supply device is at a normal level.

[0067] Step S3023, when the second-level remaining oil quantity is less than or equal to the first oil quantity threshold, output a second-level power-off protection signal; the second-level power-off duration is obtained by the second-level power-off duration formula through the second-level power consumption and the second-level stored power obtained in adjacent two times, and the second-level power-off duration is output; the second-level power-off duration formula is configured as: Wherein, T2d is the second-level power-off duration, D2c is the second-level stored power, d1 is the first reserved power, D2y i and D2y i-1 are the second-level power consumptions obtained in adjacent two times, t1 is the first power consumption detection duration; D2y i-1 is the second-level power consumption obtained in the previous time, and D2y i is the second-level power consumption obtained in the next time.

[0068] Step S3024, when the third-level remaining oil quantity is less than or equal to the second oil quantity threshold, output a third-level power-off protection signal; the third-level power-off duration is obtained by the third-level power-off duration formula through the third-level power consumption and the third-level stored power obtained in adjacent two times, and the third-level power-off duration is output; the third-level power-off duration formula is configured as: Wherein, T3d is the third-level power-off duration, D3c is the third-level stored power, d2 is the second reserved power, D3y j and D3y j-1 are the third-level power consumptions obtained in adjacent two times, t2 is the second power consumption detection duration. D3y j-1 is the third-level power consumption obtained in the previous time, and D3y j is the third-level power consumption obtained in the next time. Wherein, the first oil quantity threshold is greater than the second oil quantity threshold, because the risk level of the third emergency detection mode is less than that of the second emergency detection mode, so the second reserved power set in the third emergency detection mode is less than the first reserved power in the second emergency detection mode.

[0069] The intelligent protection module is configured with an intelligent protection strategy, and the intelligent protection strategy includes: performing power consumption protection on the passenger car based on protection data. The intelligent protection module includes an alarm reminding device, and the alarm reminding device adopts a warning loudspeaker. The intelligent protection module is configured with an intelligent protection strategy, and the intelligent protection strategy includes the following steps:

[0070] Step S401, when receiving the primary power-off protection signal and the secondary power-off protection signal, closing the power supply device and the power consumption device; when receiving the secondary power-off duration, closing the power supply device and the power consumption device after the secondary power-off duration;

[0071] Step S402, when receiving the normal power-off protection signal and the tertiary power-off protection signal, closing the power supply device and the power consumption device, and starting the alarm reminding device to alarm; when receiving the tertiary power-off duration, closing the power supply device and the power consumption device after the tertiary power-off duration.

[0072] Working principle: firstly, the personnel detection module detects the personnel in the driving position and the number of personnel in the passenger cabin; then the power consumption detection module can detect the power consumption data and power supply data of the passenger car; the passenger car master control data acquisition module is used to acquire the basic running data of the passenger car, and the power consumption analysis module can analyze the personnel detection data acquired by the personnel detection module, and divide the detection mode according to the personnel detection data; based on different detection modes, the power consumption and power storage data and the basic running data of the passenger car are analyzed, and the corresponding protection data is output; finally, the intelligent protection module protects the power consumption of the passenger car based on the protection data.
