It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
One embodiment of the present invention, as shown in fig. 1, is a method for prompting an in-vehicle article, including:
s100, when the opening of the vehicle door is monitored, detecting articles in each storage space in the vehicle through a sensor to obtain detection information;
s200, when the result of analyzing the detection information is that an article is detected, identifying a target prompt lamp corresponding to the position of the article;
s300, starting the target prompting lamp for prompting, and simultaneously starting voice prompting.
Specifically, in this embodiment, when monitoring that the car door is opened, that is to say when obtaining the door opening signal, open each sensor that is used for detecting storing space, thereby carry out article detection to each storing space in the car and obtain detection information, the quantity of sensor can set up based on storing space's distribution and size.
When the result of the detection information obtained by the analysis sensor is that the article is detected, the position of the article is further identified, namely the position of the storage space where the article is placed is identified. Wherein, each storing space disposes respective warning light respectively, and the warning light is opened and is explained and have article to leave over in the corresponding storing space. The prompt lamps of the storage spaces are arranged in the storage spaces and can represent the storage spaces, and meanwhile, the positions can be conveniently seen, or all the prompt lamps are arranged at the same position, but the storage spaces corresponding to the prompt lamps are marked.
Therefore, after the position of the object in the vehicle is determined, the target prompting lamp in the storage space is confirmed, then the target prompting lamp is turned on, and meanwhile the voice prompt is turned on. The light prompt mode and the voice prompt mode can be freely set based on user selection, for example, the target prompt lamp is turned on for a long time, or the target prompt lamp flickers in a breathing lamp mode for 20 seconds. The voice prompt can play voice of 'please take articles away' or play music audio, etc.
Then, if the user takes the left-over article away, the target prompting lamp is turned off, and simultaneously, the voice prompt is turned off or voice such as 'article taken away' is played. If the user does not remove the object within the predetermined time, the frequency and sound intensity of the voice prompt may be gradually increased to enhance the prompting effect.
According to the invention, when the vehicle door is opened, the article detection is carried out on the article storage space in the vehicle, then the user is prompted that articles are left in the article storage space in the vehicle, and meanwhile, the corresponding position of the article storage space is pointed, so that the article omission is avoided, and the user can conveniently and quickly determine the position of the article.
Preferably, in another embodiment of the present invention, when it is detected that the vehicle door is opened, before the detecting information is obtained by detecting the articles in each storage space in the vehicle through the sensor, the method further includes: s010 monitors the state of a car door membrane switch; and S020 sending out a vehicle door opening signal when the membrane switch is in the bouncing state.
Specifically, when the automobile door is closed, the membrane switch is in a pressed state; when the automobile door is opened, the membrane switch is in a bouncing state. Thus, the detection of the door opening can be achieved by detecting the state of the membrane switch.
Furthermore, the state of the membrane switch can only detect whether the vehicle door is opened, and the condition that a user gets on the vehicle or gets off the vehicle or simply opens the vehicle door cannot be further judged. Therefore, the human body induction sensor can be arranged in the vehicle and used for detecting the number of people in the vehicle. When the door of the vehicle is detected to be opened and the number of people in the vehicle is detected to be reduced by the human body induction sensor, the user is determined to get off the vehicle, the object detection can be started again to perform corresponding prompt, otherwise, the prompt is not performed.
According to the invention, whether the vehicle door is opened or not can be visually and accurately identified through the state of the membrane switch, so that article detection is triggered, and article leaving of a user is avoided. Meanwhile, whether article prompt is carried out or not is further confirmed through the change of the number of people in the vehicle detected by the human body induction sensor, and error prompt is avoided.
Another embodiment of the present invention is an optimized embodiment of the above-mentioned embodiment, as shown in fig. 2, compared with the above-mentioned embodiment, the main improvement of this embodiment is that the step S210 of analyzing the detection information to detect the article specifically includes:
s211, analyzing the detection information of each sensor;
s212, when the detection information of any sensor for a certain storage space is smaller than a corresponding preset threshold value, determining that the any sensor detects that articles exist in the certain storage space;
s213, when the number of the sensors exceeding the preset number judges that articles exist in the certain storage space, the certain storage space is judged to detect the articles.
Specifically, in this embodiment, when it is monitored that the vehicle door is opened, that is, when a door opening signal is obtained, each sensor for detecting the storage space is opened, and thus, each storage space in the vehicle is detected for articles to obtain detection information.
And analyzing the detection information to identify whether the article is left over. Because there are a plurality of sensors, there are a plurality of storing spaces in the car simultaneously, and it is nearer to have two storing spaces, within the signal processing scope of same sensor, consequently, each sensor is to the detection information of each storing space in own signal range respectively to the analysis. When the detection information of any sensor for a certain storage space is smaller than a corresponding preset threshold value, it is judged that any sensor detects that articles exist in the certain storage space. Meanwhile, due to the fact that the sensors of each storage space are arranged differently, the corresponding preset threshold values of each sensor are different, and the preset threshold values are calibrated respectively after the sensors are installed.
For example, when a sharp infrared distance measuring sensor (1cm-30cm) is selected as the article detection input, the analog quantity (i.e., detection information) of the infrared sensor is collected, and then filtering is performed twice, and an object is considered to be detected when the sensor output analog quantity is smaller than a threshold value, and is considered not to be detected when the sensor output analog quantity is larger than the threshold value.
In addition, the misjudgment probability of the judgment result of the single sensor is higher, so that the storage space is judged to detect the articles only when the number of the sensors exceeding the preset number is judged to have the articles in the unified storage space. That is, when one or more sensors in the same installation area detect an object, the area is considered to have the object, the specific number is determined by the installation condition, for example, the storage compartment is provided with 5 sensors, and when more than 2 sensors detect the object, the storage compartment is considered to have the object.
When the result of the detection information obtained by the analysis sensor is that an article is detected, the position of the article is further identified, namely the position of the storage space in which the article is placed is identified, then the target prompt lamp in the storage space is confirmed, then the target prompt lamp is turned on, and meanwhile, the voice prompt is turned on. Then, if the user takes the left-over article away, the target prompting lamp is turned off, and simultaneously, the voice prompt is turned off or voice such as 'article taken away' is played. If the user does not remove the object within the predetermined time, the frequency and sound intensity of the voice prompt may be gradually increased to enhance the prompting effect.
The invention adopts a plurality of sensors to detect whether articles are left in the same storage space, and meanwhile, the articles are judged to be left only when the articles are detected according to the detection results of the sensors with the number exceeding the preset number, so that the probability of misjudgment is reduced.
Preferably, in another embodiment of the present invention, the step S220 of identifying the target guidance light corresponding to the position of the article specifically includes: s221, identifying a sensor label corresponding to the sensor for judging the article; s222, determining the position of the article according to the sensor label; or, S223 determines the position of the article according to the signal intensity of the sensor for judging the existence of the article; s224, analyzing a target warning light corresponding to the position of the article.
Specifically, the arrangement of the sensors is divided into two modes, wherein the first mode is that different sensors respectively monitor specific storage spaces, each sensor is labeled, and the sensors correspond to the sensor labels one to one. Each storage space corresponds to a plurality of sensors, and when the detection information acquired by the sensors is analyzed, the storage space corresponding to the detection information can be determined by identifying the marks of the sensors. And the second mode is that all the sensors are reasonably distributed to detect the storage space of the whole vehicle. And then judging the storage space corresponding to the detection information according to the installation position of the sensor, the sensor signal intensity corresponding to the detection information and the position of each storage space.
Based on the arrangement mode of the two sensors, the positions of the articles are determined according to the sensor marks or the signal intensity of the sensors respectively, then the corresponding storage spaces are determined, the corresponding target prompt lamps are analyzed, and then prompt is carried out.
According to the invention, the sensors in different storage spaces are labeled, and a specific area monitoring mode is adopted, so that the storage spaces corresponding to the left articles can be conveniently and rapidly determined, and then the user is prompted. In addition, the mode of monitoring the whole vehicle by all the sensors can be selected, the number of the arranged sensors is reduced, and the cost is reduced.
One embodiment of the present invention, as shown in fig. 3, is an in-vehicle article reminder system 100, including:
the vehicle door monitoring module 110 is used for monitoring the state of a vehicle door membrane switch and sending a vehicle door opening signal when the membrane switch is in a bouncing state;
the article detection module 120 is used for detecting articles in each storage space in the vehicle to acquire detection information when the vehicle door is monitored to be opened;
the data processing module 130 analyzes the detection information acquired by the article detection module 120, and identifies a target warning light corresponding to the position of the article when the article is detected;
the data processing module 130 specifically includes:
an information analysis unit 131 that analyzes detection information of each sensor;
the data processing unit 132 is configured to determine that an article exists in a certain storage space detected by any sensor when the information analysis unit 131 obtains that the detection information of any sensor for the certain storage space is smaller than a corresponding preset threshold;
the data processing unit 132 determines that an article exists in the certain storage space when the number of the sensors exceeds a preset number, and determines that the article is detected in the certain storage space;
a mark identification unit 133 that identifies a sensor mark corresponding to a sensor for determining the presence of an article;
a position analyzing unit 134 for determining the position of the article according to the sensor label identified by the label identifying unit 133; or the like, or, alternatively,
the position analysis unit 134 determines the position of the article according to the signal intensity of the sensor for judging the existence of the article;
the data analysis unit 135 is used for analyzing the target warning light corresponding to the position of the article obtained by the position analysis unit 134;
and the prompting module 140 starts the target prompting lamp determined by the data processing module 130 for prompting, and simultaneously starts voice prompting.
Specifically, in this embodiment, when monitoring that the car door is opened, that is to say when obtaining the door opening signal, open each sensor that is used for detecting storing space, thereby carry out article detection to each storing space in the car and obtain detection information, the quantity of sensor can set up based on storing space's distribution and size.
And analyzing the detection information to identify whether the article is left over. Because there are a plurality of sensors, there are a plurality of storing spaces in the car simultaneously, and it is nearer to have two storing spaces, within the signal processing scope of same sensor, consequently, each sensor is to the detection information of each storing space in own signal range respectively to the analysis. When the detection information of any sensor for a certain storage space is smaller than a corresponding preset threshold value, it is judged that any sensor detects that articles exist in the certain storage space. Meanwhile, due to the fact that the sensors of each storage space are arranged differently, the corresponding preset threshold values of each sensor are different, and the preset threshold values are calibrated respectively after the sensors are installed.
For example, when a sharp infrared distance measuring sensor (1cm-30cm) is selected as the article detection input, the analog quantity (i.e., detection information) of the infrared sensor is collected, and then filtering is performed twice, and an object is considered to be detected when the sensor output analog quantity is smaller than a threshold value, and is considered not to be detected when the sensor output analog quantity is larger than the threshold value.
In addition, the misjudgment probability of the judgment result of the single sensor is higher, so that the storage space is judged to detect the articles only when the number of the sensors exceeding the preset number is judged to have the articles in the unified storage space. That is, when one or more sensors in the same installation area detect an object, the area is considered to have the object, the specific number is determined by the installation condition, for example, the storage compartment is provided with 5 sensors, and when more than 2 sensors detect the object, the storage compartment is considered to have the object.
When the result of the detection information obtained by the analysis sensor is that the article is detected, the position of the article is further identified, namely the position of the storage space where the article is placed is identified. Wherein, each storing space disposes respective warning light respectively, and the warning light is opened and is explained and have article to leave over in the corresponding storing space. The prompt lamps of the storage spaces are arranged in the storage spaces and can represent the storage spaces, and meanwhile, the positions can be conveniently seen, or all the prompt lamps are arranged at the same position, but the storage spaces corresponding to the prompt lamps are marked.
Specifically, the arrangement of the sensors is divided into two modes, wherein the first mode is that different sensors respectively monitor specific storage spaces, each sensor is labeled, and the sensors correspond to the sensor labels one to one. Each storage space corresponds to a plurality of sensors, and when the detection information acquired by the sensors is analyzed, the storage space corresponding to the detection information can be determined by identifying the marks of the sensors. And the second mode is that all the sensors are reasonably distributed to detect the storage space of the whole vehicle. And then judging the storage space corresponding to the detection information according to the installation position of the sensor, the sensor signal intensity corresponding to the detection information and the position of each storage space.
Based on the arrangement mode of the two sensors, the position of the object is determined according to the sensor marks or the signal intensity of the sensors respectively, the corresponding storage space is further determined, the corresponding target prompt lamp is analyzed, then the target prompt lamp is turned on, and meanwhile voice prompt is turned on. The light prompt mode and the voice prompt mode can be freely set based on user selection, for example, the target prompt lamp is turned on for a long time, or the target prompt lamp flickers in a breathing lamp mode for 20 seconds. The voice prompt can play voice of 'please take articles away' or play music audio, etc.
Then, if the user takes the left-over article away, the target prompting lamp is turned off, and simultaneously, the voice prompt is turned off or voice such as 'article taken away' is played. If the user does not remove the object within the predetermined time, the frequency and sound intensity of the voice prompt may be gradually increased to enhance the prompting effect.
According to the invention, when the vehicle door is opened, the article detection is carried out on the article storage space in the vehicle, then the user is prompted that articles are left in the article storage space in the vehicle, and meanwhile, the corresponding position of the article storage space is pointed, so that the article omission is avoided, and the user can conveniently and quickly determine the position of the article.
When the automobile door is closed, the membrane switch is in a pressed state; when the automobile door is opened, the membrane switch is in a bouncing state. Thus, the detection of the door opening can be achieved by detecting the state of the membrane switch.
Furthermore, the state of the membrane switch can only detect whether the vehicle door is opened, and the condition that a user gets on the vehicle or gets off the vehicle or simply opens the vehicle door cannot be further judged. Therefore, the human body induction sensor can be arranged in the vehicle and used for detecting the number of people in the vehicle. When the door of the vehicle is detected to be opened and the number of people in the vehicle is detected to be reduced by the human body induction sensor, the user is determined to get off the vehicle, the object detection can be started again to perform corresponding prompt, otherwise, the prompt is not performed.
According to the invention, whether the vehicle door is opened or not can be visually and accurately identified through the state of the membrane switch, so that article detection is triggered, and article leaving of a user is avoided. Meanwhile, whether article prompt is carried out or not is further confirmed through the change of the number of people in the vehicle detected by the human body induction sensor, and error prompt is avoided.
