Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer and more complete, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a washing machine, which may include:
the system comprises a first camera module 101, an infrared distance measuring sensor 102, a processor 103, an operation module 104, an alarm module 105 and at least one control key 106;
the first camera module 101 is configured to be triggered by the processor 103, shoot an image, and send the image to the processor 103;
the infrared distance measuring sensor 102 is used for sensing a distance value of an external object from the washing machine in real time;
the processor 103 is configured to acquire a distance value sensed by the infrared ranging sensor 102 in real time, and determine whether the acquired distance value is not greater than a preset distance threshold; when the acquired distance value is not greater than the distance threshold value, judging whether the operation module 104 is currently operated, if so, triggering the first camera module 101 to shoot an image; judging whether a face image exists in the image by performing face recognition on the image sent by the first camera module 101, wherein the age value corresponding to the face image is not greater than a preset age threshold value, if so, controlling the operation module 104 to pause operation, and controlling the alarm module 105 to alarm and remind; monitoring whether each control key 106 is triggered from the outside; when any control key 106 is monitored to be triggered externally, whether the operation module 104 is suspended currently is judged, and if yes, the operation is finished.
The washing machine provided by the embodiment of the invention comprises a camera module, an infrared distance measuring sensor, a processor, an operation module, an alarm module and control keys. The processor judges whether a distance value, which is sensed by the infrared distance measuring sensor in real time, of an external object from the washing machine is not greater than a distance threshold value or not, if so, judges whether the operation module is currently operated or not, and triggers the camera module to shoot an image during operation; the method comprises the steps that face recognition is carried out on an image shot by a camera module, whether a face image with a corresponding age value not greater than an age threshold exists in the image or not is judged, if yes, an operation module is controlled to pause operation, and an alarm module carries out alarm reminding; and when any control key is monitored to be triggered externally, judging whether the operation module is suspended currently, and if so, ending the operation. Once the condition that a child approaches the washing machine is monitored, the operation can be suspended and the key is locked, so that the embodiment of the invention can better protect the safety of the child.
In detail, the infrared distance measuring sensor can comprise a light emitter and a receiver, infrared light emitted by the light emitter is blocked by an object, reflected infrared light enters the receiver, and the distance between the infrared distance measuring sensor and the object can be reflected according to the time difference.
So, can set up infrared distance measuring sensor in the suitable position department on the washing machine shell to make children appear when washing machine is peripheral, infrared distance measuring sensor can sense children apart from washing machine's distance. Of course, the arrangement of the infrared distance measuring sensors may be set to be plural as required based on the seating position and the peripheral layout of the washing machine. For example, when two sides of the washing machine are close to the wall and the peripheries of the other two sides are vacant, two infrared distance measuring sensors can be respectively arranged on the outer surfaces of the washing machine which are not close to the two sides of the wall.
Considering the rapidity, uncertainty, etc. of the child's activities, the infrared distance measuring sensor preferably starts sensing in real time after the washing machine is powered on. Once the distance sensed by the infrared distance measuring sensor is not greater than the preset distance threshold, for example, 3m is taken as an example, it may be that the child is at a position less than 3m away from the washing machine, and therefore, if the washing machine is running at this time, in order to ensure the safety of the child, the face recognition may be combined to further determine whether the object less than 3m away from the washing machine is the child. Of course, the washing machine is not in operation, not a child, i.e. no treatment is required.
Based on the above, the processor may trigger the first camera module to capture an image, where the captured image should include an image of an object less than 3m away from the washing machine. Therefore, the camera shooting area of the first camera shooting module is consistent with the sensing area of the infrared distance measuring sensor. Of course, when a plurality of infrared distance measuring sensors exist, a plurality of first camera modules can be correspondingly arranged. When the distance value sensed by any infrared distance measuring sensor is not more than 3m, the corresponding first camera module is triggered to work.
In addition, because the infrared distance measuring sensor senses in real time, and the child has a certain duration time from the time when the child is close to the washing machine to the time when the child is far away from the washing machine, the child usually receives a distance value which is not more than 3m and is sent by the infrared distance measuring sensor within a period of time after the child is sensed and the operation module is controlled to stop operating, and the operation can be finished because the operation is stopped, so that the first camera module is not required to be triggered repeatedly. The implementation mode can simplify the operation flow of the processor and other components as much as possible on the premise of ensuring the safety of children.
In general, when a child approaches the washing machine and the distance is not greater than 3m, the image of the face of the child can be recognized from the image sent by the first camera module. In the embodiment of the invention, the processor can identify the images by a face identification technology so as to identify each face image in the images, and further can obtain the age value of the user corresponding to each face image. If the age value of the user corresponding to a face image is not greater than a preset age threshold, for example, 6 years old, it can be determined that a child is near the washing machine and needs to perform child safety protection processing.
According to the embodiment of the invention, according to the image analysis result, when the child is determined to be close to the washing machine, the child safety protection processing can be carried out. In detail, the child safety protection process may include at least the following 3 aspects:
aspect 1: the operation module suspends the operation;
aspect 2: the alarm module is used for alarming and reminding;
aspect 3: and controlling the key to be locked.
Therefore, in the embodiment of the invention, when it is determined that a child is close to the washing machine, the processor can control the operation module to pause, for example, the washing machine can be quickly paused when being dried, and control the alarm module to give an alarm, for example, an audible and visual alarm can be given to quickly remind parents nearby the washing machine.
In detail, since the user can manipulate the control keys to issue corresponding control instructions to the washing machine, the processor can monitor whether each control key is triggered in real time. As mentioned above, the operation module is currently in the suspended operation state if the operation module is currently in the child safety protection period, and is in the normal operation state otherwise. Therefore, when a user triggers any control key, whether the operation module is suspended currently or not can be judged, if yes, the control key can be regarded as being triggered by mistake by children, so that the operation can be finished directly, corresponding control commands are not executed, the safety of children is ensured, otherwise, the control key is regarded as not being triggered by mistake by children but being normally operated by adult users, and therefore the corresponding control commands can be directly executed.
In summary, the embodiment of the invention can perform the child safety protection processing when the child approaches the washing machine by the infrared distance measurement, the face recognition and the specific processing logic, so as to ensure the safety of the child.
As mentioned above, when the child approaches the washing machine, the operation module is controlled to pause. Correspondingly, when the child is far away from the washing machine, the operation module can be controlled to recover to operate, so that the normal operation of the washing machine is ensured. Therefore, in an embodiment of the present invention, the processor 103 is configured to determine whether the operation of the operation module 104 is currently suspended when the acquired distance value is greater than the distance threshold, and if so, control the operation module 104 to continue to operate.
In the embodiment of the invention, whether objects are near the washing machine or not can be reflected according to the distance value sensed by the infrared distance measuring sensor in real time, if the sensed distance value is larger than the distance threshold value, the situation that no object exists around the washing machine is considered, and certainly, the situation that a child is not near the washing machine is also indicated, so that the operation module can be controlled to continue to operate. For example, if the operation module is suspended while spin-drying, the operation module may continue to perform the spin-drying operation.
Of course, when the distance value greater than the distance threshold is acquired again after the operation of the operation module is resumed, the operation module may be operated, and therefore, the operation may be terminated.
As mentioned above, when a child approaches the washing machine, the child safety protection process is performed, and the control button is locked, and no response is made when anyone operates the control button as long as the child safety protection process is still performed. Based on this, considering that there is a case that an adult operates the control button before coming to the washing machine even when a child approaches the washing machine, since the adult operates the washing machine, it can be considered that the washing machine has no danger to the child, so that the child safety protection process can be released.
Therefore, in an embodiment of the present invention, referring to fig. 2, the washing machine further includes: a second camera module 201;
the second camera module 201 is configured to be triggered by the processor 103, shoot an image, and send the image to the processor 103;
the processor 103 is configured to store a control instruction corresponding to each control key 106; when any control key 106 is monitored to be triggered externally and the operation module 104 is judged to be suspended currently, triggering the second camera module 201 to shoot an image; and performing face recognition on the image sent by the second camera module 201, and judging whether a face image exists in the image, wherein the age value corresponding to the face image is greater than the age threshold, if so, controlling the operation module 104 to continue operating, and executing a control instruction corresponding to the control key 106 triggered by the outside, otherwise, ending.
In the embodiment of the present invention, preferably, the setting position of the second camera module may satisfy: when the user operates the control key, the face area of the user can fall into the shooting range of the second shooting module.
In the embodiment of the invention, any control key is triggered from the outside, and the operation module is currently suspended, namely, when the operation module is still in the period of child safety protection, the second camera module can be combined to determine whether an operator of the control key is an adult or not. As above, the image shot by the second camera module can be subjected to face recognition, if the age value is larger than the age threshold value, namely the face image of an adult, the operation module can be controlled to continue to operate, so that the child safety protection is removed, and a corresponding control instruction is executed.
In detail, for learning an age value through face recognition, there are various implementations.
For example, each face image in the image may be recognized first, and then the face information of each recognized face image is obtained by combining the existing recognition technology, which may be the age and the gender, and the obtained age value may be compared with an age threshold.
For another example, at least one face image of a child at home may be stored in advance, and after each face image in the images is recognized, the matching degree of the face images may be calculated. And if the matching degree of the identified face image and the stored face image is not less than the threshold value of the matching degree, indicating that the child is close to the washing machine. Of course, the child's age is not greater than the age threshold.
In detail, for the implementation of image matching, in an embodiment of the present invention, the processor 103 is configured to store at least one facial image, where an age value of a user corresponding to each facial image is not greater than the age threshold; judging whether a face image exists in the image sent by the first camera module 101, if so, respectively calculating the matching degree between each face image in the image and each stored face image until the matching degree is not less than a preset matching degree threshold value; when the matching degree not less than the threshold value of the matching degree is calculated, the operation module 104 is controlled to stop operating, and the alarm module 105 is controlled to give an alarm.
In the embodiment of the invention, in order to ensure the accurate matching of the images, a plurality of face images can be preset for the same child. The number of face images recognized is usually one. Therefore, the matching degree of the recognized face image and each pre-stored face image can be calculated respectively, once the matching degree which is not less than the threshold value of the matching degree is calculated, the fact that a child is near the washing machine is indicated, calculation can be stopped, and otherwise, calculation is continued. If the calculation is finished, the matching degree which is not less than the threshold value of the matching degree is still calculated, namely, no child is near the washing machine. When a child is near the washing machine, the child safety protection treatment can be carried out.
In some specific cases, a child may come near the washing machine, but the image captured by the first camera module does not include the image of his face, such as when the child is near the washing machine when playing backwards. In this case, it is easy to cause erroneous judgment that no child is present near the washing machine. To solve this problem, any one or more of the following auxiliary operations may be performed:
operation 1: judging whether the child is close to the washing machine or not by combining the electronic tag;
operation 2: judging whether the child is close to the washing machine or not by combining the human body contour information;
operation 3: judging whether the child is close to the washing machine or not according to the height of the child;
and operation 4: and judging whether the child is close to the washing machine or not by combining the sound.
In detail, for operation 1:
in an embodiment of the present invention, referring to fig. 2, the washing machine further includes: an electronic tag sensor 202;
wherein the sensing distance of the electronic tag sensor 202 is not greater than the distance threshold;
the electronic tag sensor 202 is configured to sense whether an electronic tag exists in a surrounding environment, and if so, send tag information carried by the sensed electronic tag to the processor 103, otherwise, send notification information that the electronic tag is not sensed to the processor 103;
the processor 103 is configured to store tag information of at least one electronic tag; receiving the tag information sent from the electronic tag sensor 202; judging whether the stored label information comprises the received label information, if so, controlling the operation module 104 to pause operation, and controlling the alarm module 105 to alarm; and receiving the notification information, and judging whether the operation module 104 is suspended currently, if so, controlling the operation module 104 to continue to operate.
In detail, an electronic tag carrying tag information may be worn on a child. The electronic tag sensor may be disposed on an outer surface of the washing machine and have a sensing distance, which may be 3m, for example. When the electronic tag is beyond 3m, the electronic tag sensor will not sense the existence of the electronic tag. Therefore, when the distance between the child wearing the electronic tag and the washing machine is less than 3m, the electronic tag sensor can send the tag information carried by the child wearing the electronic tag to the processor.
In order to ensure the judgment accuracy, the processor receives the label information, can compare the label information with the pre-stored label information, and if the label information is consistent, the processor determines that a child is near the washing machine. This comparison operation is particularly applicable to application scenarios where there are many types of electronic tags in a home environment.
In detail, for operation 2:
in an embodiment of the present invention, referring to fig. 2, the washing machine further includes: an infrared thermal imaging camera 203;
the infrared thermal imaging camera 203 is configured to be triggered by the processor 103, shoot an infrared thermal imaging image, and send the infrared thermal imaging image to the processor 103;
the processor 103 is configured to store at least one piece of human body contour information, where an age value of a user corresponding to each piece of human body contour information is not greater than the age threshold; when it is determined that a face image does not exist in the image sent by the first camera module 101 and the age value corresponding to the face image is not greater than the age threshold, triggering the infrared thermal imaging camera 203 to shoot an image; extracting human body contour information in an infrared thermal imaging image sent by the infrared thermal imaging camera 203; judging whether the extracted human body contour information comprises human body contour information, wherein the human body contour information is consistent with stored human body contour information, if so, executing: control the run module 104 to suspend operation.
In detail, the infrared thermal imaging camera can shoot a specific sampling region to obtain a temperature distribution image of a human body in the region, and then human body contour information is obtained according to the temperature distribution image.
In the embodiment of the invention, at least one piece of human body contour information of the child members in the family can be stored in advance. When the extracted human body contour information is consistent with or matched with the pre-stored human body contour information, the child is considered to be close to the washing machine, so that the child safety protection treatment can be carried out.
In the embodiment of the invention, the distance measurement result indicates that an object is close to the washing machine, but when the face identification result indicates that no child is close to the washing machine, in order to better ensure the judgment accuracy, whether the child is close to the washing machine or not can be further determined by the human body contour information. If the judgment result is still negative, the child safety protection processing is not required to be executed, otherwise, the child safety protection processing is required to be executed.
In detail, for operation 3:
based on the above technical implementation of the operation 2, in an embodiment of the present invention, the extracted human body contour information may include a human body height value, since there is a significant difference between heights of adults and children, a height threshold may be preset, and when the extracted human body height values are greater than the height threshold, it may be determined that no child is close to the washing machine, so that it is not necessary to perform child safety protection operation, whereas when a human body height value not greater than the height threshold is extracted, it may be determined that a child is close to the washing machine, so that child safety protection operation may be performed.
In detail, for operation 4:
in an embodiment of the invention, when the first camera module is triggered to shoot images, sounds in the surrounding environment of the washing machine are sampled, whether the collected sounds include sounds of children or not is determined through analysis of the sounds, if yes, the operation module is controlled to stop operating, and the alarm module is controlled to give an alarm.
In detail, the sound analysis may be performed by the sound length in consideration of the difference in sound length between the adult sound and the child sound.
In conclusion, by combining the above operations, the misjudgment of the processor can be reduced as much as possible, and the method is particularly suitable for special application scenes in which children are close to the washing machine and cannot normally acquire face images of the children, and the safety of the children is guaranteed as much as possible.
In detail, considering that the operation module is powered by strong electricity in reality, and in order to avoid the threat of the strong electricity to the safety of the child, the child safety protection process may further include the following aspect 4 in addition to the above 3 aspects:
aspect 4: the strong current supply is stopped.
In detail, with respect to the above aspect 4:
in an embodiment of the present invention, referring to fig. 2, the washing machine further includes: a mains supply module 204 and a storage battery 205;
the processor 103 is configured to control the commercial power supply module 204 to stop supplying power to the operation module 104 when the operation module 104 is controlled to suspend operation;
the commercial power supply module 204 is configured to supply power to the operation module 104 and charge the storage battery 205;
the storage battery 205 is configured to supply power to the first camera module 101, the infrared distance measuring sensor 102, the processor 103, and the alarm module 105.
In the embodiment of the invention, when the children are determined to be close to the washing machine, the strong current power supply is stopped, and when the children are determined to be far away from the washing machine, the strong current power supply is recovered. Meanwhile, in order to monitor the distance change between the child and the washing machine, to execute the child safety protection processing and release the child safety protection processing as required, the weak current power supply is uninterrupted under the condition that the storage battery is continuously electrified.
As mentioned above, the alarm module on the washing machine can be used for alarm reminding, so that adults nearby the washing machine can be reminded quickly. However, when the area of the house is large, so that parents cannot timely and obviously sense special conditions such as alarm reminding and temporary going-out of the family, the alarm reminding is notified in the washing machine, and the alarm reminding can be simultaneously notified to the parents through the intelligent mobile terminal.
Based on this, in an embodiment of the present invention, the processor 103 is configured to send a face image to a server when it is determined that the image sent by the first camera module 101 has a face image, and an age value corresponding to the face image is not greater than the age threshold, so as to notify the server to push the image to an intelligent mobile terminal corresponding to the washing machine.
In the embodiment of the invention, the image shot when the child is detected to be close to the washing machine can be forwarded to the corresponding intelligent mobile terminal through the server.
Based on the above, as shown in fig. 3, the present invention provides a system for securing children, which may include: a server 301, at least one washing machine 302, at least one intelligent mobile terminal 303;
the server 301 is configured to determine an intelligent mobile terminal 303 corresponding to each washing machine 302; receiving an image sent by any one of the washing machines 302, and pushing the image to the intelligent mobile terminal 303 corresponding to the washing machine 302;
each intelligent mobile terminal 303 is configured to receive the image sent by the server 301, display the received image, and perform an alarm prompt.
In the embodiment of the invention, when the processor in the washing machine judges that a face image exists in the image sent by the first camera module and the age value corresponding to the face image is not greater than the age threshold value, the processor sends the image to the server.
When the intelligent mobile terminal performs alarm reminding, the intelligent mobile terminal can remind a user that children are close to the washing machine, and the user can check specific conditions through images displayed by the intelligent mobile terminal.
The embodiment of the invention judges the distance of a person approaching the washing machine through infrared distance measurement, judges whether the biological characteristics of the person approaching the washing machine are children or not through face recognition, and triggers the early warning system only when the person is a child and the distance from the person to the washing machine is less than the set safety distance. The washing machine gives out alarm sound, the machine is suspended from running, and meanwhile, messages are pushed to the mobile phone of parents to remind the parents to take the children away from the washing machine. In addition, when the face of the user identifies the child, all keys of the washing machine do not respond, so that the child can be prevented from pressing the washing machine indiscriminately.
In addition, the preset information in the washing machine can be input through an intelligent mobile terminal of a user, such as a smart phone. For example, taking the input of the child face information as an example, the child face information may be input through a mobile phone, and the input of the child face information through the mobile phone is then transmitted to the washing machine through the network. The change of the face information can also be operated by the mobile phone. The mobile phone can directly check the conditions around the washing machine through the face recognition camera by issuing a specific control command.
As shown in fig. 4, an embodiment of the present invention provides a method for securing children safety, which is applied to any one of the above washing machines, and may include the following steps:
step 401: an infrared ranging sensor in the washing machine senses a distance value of an external object from the washing machine in real time.
Step 402: and a processor in the washing machine acquires the distance value sensed by the infrared distance measuring sensor in real time and judges whether the acquired distance value is not greater than a preset distance threshold value.
Step 403: and when the acquired distance value is not greater than the distance threshold value, the processor judges whether an operation module in the washing machine is in operation currently, and if so, a first camera module in the washing machine is triggered to shoot images.
Step 404: the first camera module is triggered by the processor, shoots an image and sends the image to the processor.
Step 405: the processor identifies the face of the image sent by the first camera module, judges whether a face image exists in the image, the age value corresponding to the face image is not greater than a preset age threshold value, and controls the operation module to pause if the face image is not greater than the preset age threshold value, and controls the alarm module in the washing machine to alarm and remind.
Step 406: the processor monitors whether the outside triggers each control button on the washing machine.
Step 407: and when monitoring that any control key is triggered from the outside, the processor judges whether the operation module is suspended currently, and if so, the current process is ended.
