Seals, commonly used for closing portals or sealing objects, are usually marked with sealing information such as sealing person, sealing date, etc. For example, commonly used seals are often marked with "seal" or "seal" eyes, and are marked with seal events, seal persons, and/or seal times. The seal is generally of a suitable length and width to facilitate attachment to a corresponding attachment location, for example, when the article to be sealed is small, it may be attached to the package of the article to be sealed. When the sealed articles are houses, the sealed seals are larger and are generally attached to two different doors of a house gate, or a single door and a door frame, so that the sealed real estate gate is prevented from being opened under the condition that the seals are not damaged, and the articles in the sealed real estate gate are prevented from being lost or turned over. When valuable or dangerous goods are sealed, a prompt or a safety slogan and the like are marked on the seal.
Traditional seals are mostly paper, and have a plurality of defects: first, paper seals are printed matter, which are easily damaged, even by non-human, and thus require periodic inspection by a supervisory personnel. For example, rain, wind, fire, etc. may damage the seal. Secondly, paper seals are easy to imitate, and the imitation cost is low. Again, the paper seal can only be used once and cannot be recycled. Finally, paper seals are easily broken and lack means to monitor the seal for vandalism and fixed evidence. It is difficult for the depositor to find a seal breaker.

Referring to fig. 1 to 6 of the drawings, an electronic seal according to an embodiment of the present invention is illustrated, wherein the electronic seal comprises a housing 10, a camera module 20, at least one body sensing device 30 and a control module 40, wherein the housing forms an attaching side 101 and a displaying side 102, the camera module 20 is configured to take an image, the body sensing device is configured to sense a human body, and the control module 40 is configured to control the camera module 20 and take an image when the body sensing device senses the presence of a human body.

Preferably, the housing 10 has a receiving cavity 100, wherein the camera module 20, the body sensing device 30 and the control module 40 are received in the receiving cavity 100. Preferably, the control module 40 is configured to generate a photographing instruction to control the camera module 20 to photograph images. Preferably, the photographing instruction generated by the control module 40 is responsive to the human body sensing signal generated by the human body sensing device 30. Alternatively, the shooting instruction generated by the control module 40 may also come directly from a terminal 80. For example, when the body sensing device 30 of the electronic seal of the present invention senses a body within the sensing range, the body sensing device 30 generates a corresponding body sensing signal, and the control module 40 is configured to generate a photographing instruction for controlling the photographing module 20 to photograph an image in response to the corresponding body sensing signal generated by the body sensing device 30.
As shown in fig. 1 to 6 of the drawings, the electronic seal according to the embodiment of the invention further comprises a main control board 50, wherein the main control board 50 is disposed in the accommodating cavity 100 of the housing 10, and the camera module 20, the body sensing device 30 and the control module 40 are fixedly disposed on the main control board 50, wherein the camera module 20 and the body sensing device 30 are respectively communicably connected with the control module 40 through the main control board 50.
As shown in fig. 1 to 6 of the drawings, the housing 10 of the electronic seal according to the embodiment of the present invention includes an upper case 11 and a lower case 12, wherein the upper case 11 and the lower case 12 form the receiving cavity 100 therebetween. Further, the upper case 11 of the housing 10 forms the display side 102, and the lower case 12 of the housing 10 forms the attachment side 101.
As shown in fig. 1 to 6 of the drawings, the electronic seal according to the embodiment of the present invention further comprises an attaching member 60, wherein the attaching member 60 is disposed on the attaching side 101 of the housing 10 to attach the electronic seal to the object to be sealed. Accordingly, the attachment side 101 of the housing 10 faces the enclosure and the display side 102 of the housing 10 faces outwardly. It will be appreciated by those skilled in the art that the display side 102 may be provided, such as printed, written or otherwise printed with words such as "seal" or "seal" indicating a seal event, and/or a seal person, and/or words or graphics of seal time. The display side 102 may also be used to display other information related to the sealing.
As shown in fig. 1 to 6 of the drawings, the attaching assembly 60 of the electronic seal according to the embodiment of the present invention includes an adhesive layer 62, wherein the adhesive layer 62 is attached to the attaching side 101 of the housing 10 to adhere the electronic seal to the container.

The electronic seal of the invention ensures the nondestructive separation of the working main body structure of the electronic seal of the invention from the attachment position by separating the working main body structure (the structure of the electronic seal of the invention except the adhesive layer 62) from the attachment position through the pull rope 63, and ensures the recovery and the reutilization of the electronic seal of the invention.
It is noted that the human body sensing device 30 of the present invention may be any device or apparatus capable of sensing the presence of a human body. For example, the human body sensing device 30 may be configured as a human body sensing device for recognizing a human body through sound; the body sensing device 30 may also be configured to identify a body sensing device of a human body by doppler technology; the human body sensing device 30 may also be configured as a human body sensing device that senses a human body through infrared detection technology. The human body sensing device 30 senses a human body continuously and periodically within a sensing range thereof, and when the human body sensing device 30 does not sense the presence of the human body, the human body sensing device 30 does not generate a human body sensing signal; when the human body sensing device 30 senses the presence of a human body within the sensing range, the human body sensing device 30 generates a corresponding human body sensing signal, and the control module 40 responds to the human body sensing signal after receiving the human body sensing signal and generates a shooting instruction capable of controlling the shooting module 20, so that the shooting module 20 is controlled and starts shooting images. It will be appreciated that the camera module 20 of the electronic seal of the present invention is configured to capture images and is the primary energy consuming component or member. Therefore, the camera module of the electronic seal is provided with a dormant state and a shooting state, and only in the state of receiving a shooting instruction, images are shot, so that the power consumption of the whole equipment can be remarkably reduced, and the working time of the electronic seal can be prolonged. Preferably, the human body sensing device 30 of the electronic seal is configured to sense human body through infrared detection technology, and the device has the advantages of quick response, low energy consumption and sensitive sensing. It will be appreciated that the camera module 20 of the electronic seal of the present invention is configured to control and capture an image of the environment only when a human body is sensed, or when a change in its posture is sensed (which may be caused by movement or damage). Preferably, the human body sensing device 30 is an infrared sensing device configured to sense a human body through infrared detection technology.
As shown in fig. 2 to 6 of the drawings, the electronic seal according to the embodiment of the present invention further includes a posture sensor 94, wherein the three-dimensional posture of the posture sensor 94 is set to be identical to the three-dimensional posture of the electronic seal according to the present invention, so that the three-dimensional posture of the electronic seal according to the present invention can be determined by detecting the three-dimensional posture of the posture sensor 94. Preferably, the attitude sensor 94 is configured to sense its own three-dimensional attitude, thereby enabling the electronic seal of the present invention to determine its own three-dimensional attitude via the attitude sensor 94. Accordingly, the change of the three-dimensional posture of the electronic seal with respect to the horizontal ground is detected or sensed by the posture sensor 94, and the deflection angle of the electronic seal with respect to the horizontal ground is determined by the change of the three-dimensional posture of the electronic seal with respect to the horizontal ground, which is detected or sensed by the posture sensor 94. Therefore, when the electronic seal of the present invention is attached to the corresponding attachment position, the user may activate the posture sensor 94, and detect the three-dimensional posture of the posture sensor 94, and compare with the three-dimensional preset value (or initial three-dimensional posture) of the posture sensor 94, so as to obtain and determine the deflection angle of the posture sensor 94 with respect to the horizontal ground.
As shown in fig. 8 and 9 of the drawings, the body sensing device 30 of the electronic seal according to the embodiment of the present invention may deflect at an angle with respect to the horizontal position (fig. 7 shows an ideal state, the electronic seal of the present invention is perpendicular to the horizontal ground along the height direction thereof), so that the body sensing device 30 and the camera module 20 deflect from the horizontal ground, and thus the body sensing device 30 may sense only the signal of the upper half of the human body, but not the signal of the lower half of the human body, and the imaging of the camera module 20 of the electronic seal of the present invention may also tilt. In order to avoid this, it is necessary to perform correction processing according to the deflection angle of the electronic seal of the present invention attached to the attachment position detected by the posture sensor 30 with respect to the horizontal ground, the sensing signal of the human body sensing device 30, and the imaging angle of the camera module 20 of the electronic seal of the present invention. It can be understood that when the deflection angle of the electronic seal of the present invention with respect to the horizontal ground is α, the sensing signal of the body sensing device 30 and the imaging angle correction angle of the camera module 20 of the electronic seal of the present invention are- α. The correction processing is performed on the sensing signal of the human body sensing device 30, so that the human body sensing device 30 senses the whole body image of the human body, and the occurrence of false positive signals and false negative signals of the sensing result of the human body sensing device 30 is avoided. When the human sensing device 30 senses only the upper body of the human, if all sensed upper body signals are positive, a false positive signal is generated. In addition, when the human body sensing device 30 senses only the upper half of the human body, a sensing blind area is generated, and a false negative signal is generated. Since the body sensing device 30 and the camera module 20 are both elements or components of the electronic seal of the present invention, the body sensing device 30 and the camera module 20 can be fixedly arranged so that the deflection angle of the body sensing device 30 and the camera module 20 relative to the horizontal ground is the same as and synchronously deflected with the deflection angle of the electronic seal of the present invention, and the three-dimensional gesture of the electronic seal of the present invention can be obtained by detecting the three-dimensional gesture of the gesture sensor 94. Accordingly, the deflection angle of the body sensing device 30 and the camera module 20 of the electronic seal of the present invention with respect to the horizontal ground can be determined by detecting the three-dimensional posture of the posture sensor 94. It will be appreciated that the control module 40 of the electronic seal of the present invention is configured to perform a correction process on the sensed signal of the body sensing device of the electronic seal of the present invention based on the deflection angle of the electronic seal (or the attitude sensor 94) of the present invention with respect to the horizontal ground. Further, the control module 40 of the electronic seal of the present invention is configured to perform a correction process on the imaging angle of the camera module 20 of the electronic seal of the present invention according to the deflection angle of the electronic seal (or the gesture sensor 94) of the present invention with respect to the horizontal ground.
Further, when the item to be stored is a large stationary object, since the attitude sensor 94 is attached at the attachment position, the distance of the attitude sensor 94 with respect to the horizontal ground can be kept unchanged, and the dimension thereof with respect to the horizontal ground is a fixed dimension. For example, when the attachment position is formed at a house or a door or window of a house. Accordingly, the three-dimensional attitude of the body sensed or sensed by the attitude sensor 94 determines the angle of deflection of the attitude sensor 94 relative to the level ground and its fixed dimensions. Accordingly, the fixed dimensions of the electronic seal of the present invention are determined. Therefore, after the electronic seal of the present invention is attached to the corresponding attachment position, the user may activate the posture sensor 94, detect the three-dimensional posture of the posture sensor 94 and compare with the three-dimensional preset value (or initial three-dimensional posture) of the posture sensor 94, so as to obtain the deflection angle of the posture sensor 94 with respect to the horizontal ground and set the fixed dimension of the posture sensor 94. The fixed dimension of the attitude sensor 94 may also be considered the fixed dimension of the electronic seal of the present invention. In other words, when the article to be sealed is a large object, unless the state thereof is abnormally changed, such as a door to which the electronic seal is attached is damaged, the relative attachment position sensed by the posture sensor 94 has a constant dimension. At this time, unless the adhesion position is abnormally changed, the fixed dimension is not changed. For example, when the electronic seal of the present invention is secured to a door, horizontal movement of the door does not change the fixed dimension of the attitude sensor 94 (or the position of the electronic seal of the present invention relative to the ground) unless the electronic seal of the present invention is detached from the attachment position or the angle of the attachment position relative to the horizontal ground changes. The user or operator can set the fixed dimension of the electronic seal of the present invention or the fixed dimension of the attitude sensor 94 of the electronic seal of the present invention through the terminal 80. When the electronic seal of the present invention is attached to a corresponding attachment position, a user or operator may activate the posture sensor 94 and detect the three-dimensional posture of the posture sensor 94, thereby obtaining a detection value of the height direction (or Y direction) of the posture sensor 94 and setting the detection value as a fixed dimension. Preferably, the posture sensor 94 is provided at the main control board 50. More preferably, the attitude sensor 94 is communicatively coupled to the control module 40 via the main control board 50.
As shown in fig. 2-6 of the drawings, the attitude sensor 94 of the electronic seal according to an embodiment of the present invention is communicatively connected to the control module 40, wherein the control module 40 is configured to generate a warning signal when the fixed dimension of the attitude sensor 94 changes. The warning signal may be transmitted to the warning device 91 to generate a warning signal or may be transmitted to a terminal 80 through the communication module 70. Preferably, the warning device 91 is communicatively connected to the control module 40.
As shown in fig. 2 to 6 of the drawings, the warning device 91 of the electronic seal according to the embodiment of the present invention is configured to respond to a warning signal. For example, when the body sensing device 30 senses that anyone is too close to (less than a predetermined distance from) the electronic seal of the present invention, the control module 40 of the electronic seal of the present invention is configured to generate a warning signal, and the warning device 91 responds to the warning signal and emits sound/light or image warning to deter from damaging the electronic seal of the present invention.

As shown in fig. 1 to 6 of the drawings, the electronic seal according to the embodiment of the present invention has a length and a width similar to those of the conventional seal (the conventional large seal has a length of about 38 cm and a width of about 11 cm, and the small seal has a length of about 30 cm and a width of about 7 cm). However, when the seal is used to seal an item, an oversized condition may be encountered with the item being sealed. For example, when the enclosed object is a real estate, such as a house of a factory building, a house, an office building, or the like. In order to ensure that the image capturing of the camera module 20 of the electronic seal of the present invention has no dead angle, when the electronic seal of the present invention is used for housing sealing, the electronic seal needs to be set according to the condition of the door of the housing. For example, when the house has two doors, two electronic seals are attached to the two doors in an inclined manner; when the house door is a single door, two electronic seals are respectively attached to the door frame and the door in an inclined mode. In addition, the relative position, the angle of view and the orientation of the camera modules of the two electronic seals also determine whether dead angles exist in the two electronic seals, which cannot be shot by the camera modules. Therefore, the camera module of the electronic seal is relatively large, and the distance between the camera module and the camera module is not too close (especially when two doors of a house are wide) and the camera module has proper orientation. Therefore, in order to ensure the sealing function of the electronic seal of the present invention, when the electronic seal of the present invention is respectively attached to the corresponding attachment positions, the pairing of the two electronic seals of the present invention may be implemented first to determine the horizontal distance between the camera modules 20 of the two electronic seals of the present invention, and the horizontal distance between the camera modules 20 of the two electronic seals according to the present invention, and the orientation of the optical lenses of the two camera modules 20 is adjusted to obtain the images of the sides of the camera modules 20 of the two electronic seals of the present invention respectively. It can be understood that the pairing between the two electronic seals can be realized by means of bluetooth technology, near field communication and other pairing means. According to the horizontal distance between the camera modules 20 of the two electronic seals, the directions of the optical lenses of the two camera modules 20 are adjusted to respectively obtain the images of the sides of the camera modules 20 of the two electronic seals, so that imaging blind areas can be effectively prevented from being formed between the camera modules 20 of the two electronic seals when the camera modules 20 of the two electronic seals are imaged in opposite directions. As described above, the deflection angle and the fixed dimension of each of the two electronic seals of the present invention with respect to the horizontal ground can be detected and determined by the respective attitude sensor 30 of the electronic seal. In addition, when the two electronic seals are respectively attached to the corresponding attachment positions, the warning function of the electronic seal can be enhanced, and the electronic seal can acquire the environmental image and timely send the environmental image to the terminal 80. When the fixed dimension of either of the attitude sensors of the two electronic seals (for example, the attitude sensor 30 of the first electronic seal 1A shown in fig. 10) changes, the control module 40 of the other electronic seal (for example, the attitude sensor 30 of the second electronic seal 1B shown in fig. 10) detects an abnormality (for example, a change in the horizontal distance therebetween) and generates a warning signal. Meanwhile, the control module 40 of the second electronic seal 1B of the present invention further generates a shooting command to control the camera module 20 of the second electronic seal of the present invention and shoot images, and the control module 40 of the second electronic seal of the present invention sends the image data generated by the camera module 20 to the terminal 80 through the communication module 70.
