Technical Field

The invention relates to a method for detecting and alerting inflammable and explosive substances in a vehicle, an intelligent system for a vehicle, a computer program product, such as a computer-readable program carrier, and a vehicle.

Background

When a vehicle driver or a vehicle occupant leaves the vehicle, it often happens that flammable and explosive substances such as a mobile phone, a charger, a lighter, etc. are left in the vehicle, and the flammable and explosive substances are exploded due to an increase in ambient temperature (for example, due to sun exposure), spontaneous combustion, etc. Such explosions can pose serious hazards to the vehicle itself, as well as to property, personnel, other animals (e.g., pets), etc. inside and outside the vehicle.

Therefore, detecting and identifying the remaining flammable and explosive materials, monitoring the corresponding temperature in the vehicle and giving an alarm to the vehicle are of great significance for preventing explosion and protecting personal and property safety.

Methods for detecting and protecting vehicle occupants are known from the prior art, wherein occupants are identified on the basis of recorded images, the vehicle interior temperature is monitored and a warning is issued when an alarm temperature is reached.

However, the prior art still has shortcomings in the specific strategy of performing temperature early warning, and a need for continued improvement exists.

s4: reminding based on a preset temperature early warning strategy, wherein the temperature early warning strategy is set as follows: and when the temperature is within one of a plurality of preset early warning level temperature intervals, sending out alarm information of a corresponding level.

The invention comprises in particular the following technical concepts: first, an image of an interior area of a vehicle is acquired, and recognition is performed based on the acquired image: whether flammable and explosive materials exist in the vehicle interior. The temperature of a predetermined region of the vehicle interior, such as the front region of the vehicle, is then monitored. In particular, in the event that the presence of a flammable explosive is identified, the temperature of the identified flammable explosive is monitored. And finally, reminding is carried out based on a preset temperature early warning strategy, wherein a plurality of early warning level temperature intervals are arranged in the temperature early warning strategy, and each early warning level temperature interval is respectively associated with the alarm information of the corresponding level. Thereby, it is achieved in an advantageous manner: corresponding alarm information is sent out according to different early warning levels, so that the urgent degree of temperature early warning is clearly indicated.

Optionally, the temperature early warning strategy is further configured to: and sending corresponding alarm information when the temperature rising change rate of the identified inflammable and explosive materials reaches a preset early warning temperature change rate threshold value. Therefore, the early warning can be issued when the fact that the temperature in the automobile rapidly rises due to insolation, spontaneous combustion and the like is recognized.

Optionally, the temperature early warning strategy is further configured to: and when the predicted temperature of the identified inflammable and explosive materials after a preset time period enters the early warning level temperature interval, sending out alarm information of a corresponding level, wherein the predicted temperature is obtained based on the prediction of a temperature monitoring result. In this case, a temperature profile of the monitoring region or of the monitoring object is detected during the temperature detection, on the basis of which the temperature of the monitoring region or of the monitoring object can be predicted after a certain time interval. This achieves in a particularly advantageous manner: according to the predicted temperature, the potential temperature rise which is possibly harmful is early warned in advance, so that the user has more sufficient time to take corresponding measures to avoid explosion.

Optionally, the plurality of warning level temperature intervals are determined according to the type of the identified inflammable explosive. Here, the type of inflammable and explosive substance may include a mobile phone, a charger, a lighter, or other inflammable and explosive substances that may explode. Advantageously, each type of inflammable explosive substance is provided with a respective warning-level temperature interval, defined differently, for example, between the mobile phone and the lighter. Therefore, corresponding early warning level temperature intervals can be set for the types of the inflammable and explosive materials with different explosive temperatures, and therefore temperature early warning can be carried out in a personalized mode.

Optionally, the alarm information includes: visual cues (e.g., text, images, light, color, etc.) and/or audible cues (beeps, voice, music, etc.) and/or tactile cues (e.g., vibration). Thereby, an appropriate reminding mode can be provided for different situations.

Optionally, the alarm information is sent to a user interaction interface, where the alarm information sent to the user interaction interface includes at least one of the following: the image of the interior of the vehicle, the type of the inflammable and explosive substances, the temperature of the inflammable and explosive substances and the early warning level. In this case, the user can take appropriate measures according to the alarm information sent to the user interface.

Alternatively, the inflammable explosive is identified based on an image recognition model, which is trained in advance by the producer of the vehicle and/or by the user. In this case, the image recognition model can be pre-trained by the vehicle manufacturer on the basis of common inflammable and explosive substances. Furthermore, the image recognition model can also be trained by the user in a user-customized manner based on the flammable and explosive substances they commonly use. In particular, the user training can not only enlarge the types of the recognizable flammable and combustible substances, but also improve the accuracy of the recognition.

Detailed Description

In order to make the technical problems, technical solutions and advantageous effects of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.

Fig. 1 shows a schematic interior space of a vehicle 1 having an intelligent system 10 according to the invention.

Fig. 2 shows a schematic block diagram of an intelligent system 10 for a vehicle 1 according to an exemplary embodiment of the present invention.

The intelligent system 10 is configured to detect and alert on flammable and explosive substances 30 within the vehicle 1. The intelligent system 1 comprises an image sensor 11, a temperature detection sensor 12 and an analysis early warning device 13.

An image sensor 11 is provided for acquiring an image of the interior of the vehicle, the image sensor 11 being, for example, an image recognition camera 41. Whether flammable and explosive materials exist in the vehicle and the type of the flammable and explosive materials (such as a mobile phone, a charger, a lighter and the like) can be identified based on the acquired vehicle interior image.

The temperature detection sensor 12 is provided for monitoring a predetermined region of the vehicle interior, in particular the real-time temperature TR of an object to be monitored (e.g., a combustible explosive 30) identified by the image sensor 11. Here, the temperature detection sensor 12 is, for example, an infrared temperature detection camera 42 that generates an infrared thermographic image based on infrared radiation emitted by the object to be monitored, thereby determining the temperature distribution of the surface of the object to be monitored.

As shown in fig. 1, an image sensor 11, for example, an image recognition camera 41 and a temperature detection sensor 12, for example, an infrared temperature detection camera 42, may be disposed near the interior rear view mirror of the vehicle for acquiring image information and temperature information of the front region in the vehicle. This front area is frequently used by passengers and is susceptible to environmental conditions (e.g. sun exposure) resulting in a significant temperature rise and is therefore an important monitoring area.

The analysis early warning device 13 is configured to analyze the temperature monitoring result and perform corresponding early warning according to the analysis result.

Optionally, the intelligent system 10 also includes a remote control unit 14 to enable remote control of the vehicle, such as starting and stopping the engine, starting and stopping the air conditioner, transmitting images of the interior of the vehicle, and the like. Optionally, the remote control unit 14 is capable of communicating with the user mobile device 20, thereby allowing control of the remote control unit 14 by the user mobile device 20. The user mobile device 20 includes, for example, a smartphone, a tablet computer, a vehicle electronic key, or other mobile terminal device capable of remote communication.

FIG. 3 illustrates a flow chart of a method for detecting and alerting of a flammable and explosive substance within a vehicle according to an exemplary embodiment of the present invention. The method can be implemented, for example, using an intelligent system 10 according to fig. 1.

In step S0, it is determined whether the detection function is activated, wherein the detection function is activated after the door lock is determined, for example, after the vehicle engine or the motor is stopped. If the determination result is that the detection function is not enabled, go to step S0'; if the determination result is that the detection function is enabled, the process proceeds to step S1.

In step S1, a vehicle interior image is acquired. This can be achieved, for example, by means of the image sensor 11.

Next, in step S2, inflammable and explosive substances 30 are identified based on the acquired vehicle interior image. Here, the recognition may be performed based on an image recognition model. Additionally, the type of flammable and explosive substance 30, such as a cell phone, a charger, a lighter, or other flammable and explosive substance type that may explode, can be identified based on the image recognition model. Optionally, the image recognition model is pre-trained by the manufacturer of the vehicle based on common flammable and explosive types. Optionally, the image recognition model is trained by the user in a user-customized manner based on the flammable and explosive substances commonly used by the user, so that the image recognition model can be supplemented or refined.

Alternatively, it is determined in step S2' whether a combustible explosive 30 is identified: if no combustible and explosive substance 30 is identified, the process proceeds to step S0'.

In step S3, the temperature of a predetermined area of the vehicle interior is monitored, and in particular, the temperature of combustible explosive 30 identified in step S2 is monitored. In this case, such a temperature monitoring can be carried out by means of the temperature detection sensor 12, wherein a time-dependent course of the temperature can be detected and the rate of change of the temperature can be determined. Additionally, based on the temperature monitoring results, the temperature of the monitored object after a certain period of time can be predicted.

Subsequently, it is determined in step S4' whether or not warning is required: if the judgment result is that the early warning is not needed, the step S0' is entered; if the determination result is that the warning is required, the process proceeds to step S4.

Alternatively, step S4 includes step S41, step S42, and step S4'. First, in step S41, it is determined whether the vehicle interior temperature rapidly increases, and when the temperature increase rate VT reaches a preset early warning temperature rate threshold VT_SThe flow proceeds to step S4'. If the temperature does not rise rapidly, the process proceeds to step S42, where it is determined whether the current temperature T rises to the warning temperature or the predicted temperature T after a certain period of time_PWhether the early warning temperature is reached. In this case, the current temperature T or the predicted temperature T_PAnd (4) when the temperature is within one of the preset early warning level temperature intervals, the step S4 'is carried out, otherwise, the step S0' is carried out. For example, n warning level temperature intervals are provided, wherein each warning level temperature interval is, for example, T1-T2, T2-T3, …, Tn-1-Tn. Here, each warning level temperature section is provided with warning information of its own level.

In step S4', the corresponding warning information is issued based on the corresponding warning situation or warning level.

It is determined whether an instruction to start the engine and/or start the air-conditioning cooling is received in step S5, and if the instruction is received, the engine and/or the air-conditioning cooling is started in step S6.

In step S0', it is determined whether an instruction for requesting remote acquisition of monitoring information is received, and if the instruction is received, the remote monitoring screen is transmitted in step S0 ″.

Although specific embodiments of the invention have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present invention.
