Referring to fig. 1 to 6 of the drawings accompanying the present specification, an electronic seal according to an embodiment of the present invention is illustrated, wherein the electronic seal includes a housing 10, a camera module 20, at least one human body sensing device 30 and a control module 40, wherein the housing forms an attachment side 101 and a display side 102, the camera module 20 is configured to capture an image, the human body sensing device is configured to sense a human body, and the control module 40 is configured to control the camera module 20 and capture an image when the human 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 human 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 shooting command to control the camera module 20 to shoot an image. Preferably, the photographing instruction generated by the control module 40 is in response 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 human body sensing device 30 of the electronic seal of the present invention senses a human body existing in the sensing range thereof, the human body sensing device 30 generates a corresponding human body sensing signal, and the control module 40 is configured to generate a shooting instruction for controlling the camera module 20 to shoot an image in response to the corresponding human body sensing signal generated by the human body sensing device 30.
As shown in fig. 1 to 6 of the drawings, the electronic seal according to the embodiment of the present invention further includes 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 human body sensing device 30 and the control module 40 are all fixedly disposed on the main control board 50, wherein the camera module 20 and the human body sensing device 30 are respectively communicably connected to the control module 40 through the main control board 50.

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 includes an attaching element 60, wherein the attaching element 60 is disposed on the attaching side 101 of the housing 10 to attach the electronic seal to the seal. Accordingly, the attachment side 101 of the housing 10 faces toward the enclosure and the display side 102 of the housing 10 faces outwardly.

It should be noted that the human body sensing device 30 of the present invention can 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 that recognizes a human body by voice; the human body sensing device 30 may also be configured with a human body sensing device for recognizing a human body by a doppler technique; the human body sensing device 30 may also be configured with a human body sensing device that senses a human body through an infrared detection technique. The human body sensing device 30 senses a human body continuously and periodically within the sensing range thereof, and when the human body sensing device 30 does not sense the existence 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 in 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 camera module 20, so that the camera module 20 is controlled and starts to shoot images. It can be understood that the camera module 20 of the electronic seal of the present invention is configured to capture images, and is a main energy consuming component or part. Therefore, the camera module of the electronic seal is set to have a dormant state and a shooting state, and the camera module can shoot images only in the state of receiving a shooting instruction, 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 of the present invention is configured to sense a human body by an infrared detection technology, and the device has the advantages of fast response, low energy consumption and sensitive sensing. It can be understood that the camera module 20 of the electronic seal of the present invention is configured to be controlled and shoot the environmental image only when sensing a human body or sensing a change in the posture of the electronic seal (which may be moved or damaged to cause a change in the posture). Preferably, the human body sensing device 30 is an infrared sensing device configured to sense a human body through an infrared detection technology.
Referring to 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 the same as the three-dimensional posture of the electronic seal of the present invention, so that the three-dimensional posture of the electronic seal of 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 the three-dimensional attitude thereof, so that the electronic seal of the present invention can determine the three-dimensional attitude thereof by the attitude sensor 94. Accordingly, the change of the self three-dimensional attitude detected or sensed by the attitude sensor 94 relative to the preset value (or preset three-dimensional attitude) of the attitude sensor 94 determines the deflection angle of the attitude sensor 94 relative to the horizontal ground, and the deflection angle of the electronic seal of the present invention relative to the horizontal ground can also be determined. Therefore, the user can activate the attitude sensor 94 when the electronic seal of the present invention is attached at the corresponding attachment position, and detect the three-dimensional attitude of the attitude sensor 94, and compare it with the three-dimensional preset value (or initial three-dimensional attitude) of the attitude sensor 94 to obtain and determine the deflection angle of the attitude sensor 94 with respect to the horizontal ground.
As shown in fig. 8 and 9 of the drawings, the human body sensing device 30 of the electronic seal according to the embodiment of the present invention may deflect at a certain angle with respect to the horizontal position (fig. 7 is an ideal state, the electronic seal of the present invention is perpendicular to the horizontal ground along the height direction thereof), so that both the human body sensing device 30 and the camera module 20 deflect with respect to the horizontal ground, and thus the human 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 image of the camera module 20 of the electronic seal of the present invention also tilts. In order to avoid this, it is necessary to perform a correction process according to the deflection angle of the electronic seal of the present invention attached to the attachment position detected by the attitude 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 electronic seal of the present invention has a deflection angle α with respect to the horizontal ground, the sensing signal of the human 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 sensing signals of the human body sensing device 30 are corrected, which is helpful for ensuring that the human body sensing device 30 senses the whole human body image, thereby preventing the sensing result of the human body sensing device 30 from generating false positive signals and false negative signals. When the human body sensing device 30 can sense only the upper half of the human body, if all sensed signals of the upper half of the human body are positive, a false positive signal is generated. In addition, when the human body sensing device 30 can only sense the upper half of the human body, a sensing blind area is generated, and a false negative signal is generated. Since the human body sensor 30 and the camera module 20 are both components or parts of the electronic seal of the present invention, the human body sensor 30 and the camera module 20 can be fixed to make the deflection angles of the human body sensor 30 and the camera module 20 relative to the horizontal ground the same as the deflection angle of the electronic seal of the present invention and deflect synchronously, and the three-dimensional posture of the electronic seal of the present invention can be obtained by detecting the three-dimensional posture of the posture sensor 94. Accordingly, the deflection angle of the human body sensing device 30 and the camera module 20 of the electronic seal of the present invention relative to the horizontal ground can be determined by detecting the three-dimensional attitude of the attitude sensor 94. It is understood that the control module 40 of the electronic seal of the present invention is configured to perform the deviation correction process on the sensing signal of the human body sensing device of the electronic seal according to the deflection angle of the electronic seal (or the attitude sensor 94) relative to the horizontal ground. Further, the control module 40 of the electronic seal of the present invention is configured to correct 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 attitude sensor 94) relative to the horizontal ground.
Further, when the article to be sealed is a large immovable object, since the attitude sensor 94 is attached to the attachment position, the distance of the attitude sensor 94 with respect to the horizontal ground can be kept constant, and the dimension thereof with respect to the horizontal ground is a fixed dimension. For example, when the attachment location is formed in a house or a door or window of a house. Accordingly, the three-dimensional attitude sensed or sensed by the attitude sensor 94 determines the degree of deflection of the attitude sensor 94 relative to the horizontal ground and its fixed dimension. Accordingly, the fixed dimension of the electronic seal of the present invention is determined. Therefore, after the electronic seal of the present invention is attached to the corresponding attachment position, the user can activate the attitude sensor 94, detect the three-dimensional attitude of the attitude sensor 94 and compare the three-dimensional attitude with the preset three-dimensional value (or initial three-dimensional attitude) of the attitude sensor 94 to obtain the deflection angle of the attitude sensor 94 with respect to the horizontal ground and set the fixed dimension of the attitude sensor 94. The fixed dimension of the attitude sensor 94 can also be considered as 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 of the article is changed abnormally, such as the door attached with the electronic seal is damaged, the relative attachment position sensed by the attitude sensor 94 has a constant dimension. At this time, unless the attachment position is abnormally changed, the fixed dimension is not changed. For example, when the electronic seal of the present invention is fixed on a door, the 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. A user or an operator can activate the attitude sensor 94 and detect the three-dimensional attitude of the attitude sensor 94 when the electronic seal of the present invention is attached to the corresponding attachment position, thereby obtaining a detection value in the height direction (or Y direction) of the attitude sensor 94 and setting the detection value to a fixed dimension. Preferably, the attitude 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.
Referring to fig. 2-6 of the drawings, the attitude sensor 94 of the electronic seal according to the embodiment of the present invention is communicably connected to the control module 40, wherein the control module 40 is configured to generate an alarm signal when the fixed dimension of the attitude sensor 94 changes. The alert signal may be transmitted to the alerting device 91 to generate an alert, or may be transmitted to a terminal 80 via the communication module 70. Preferably, the warning device 91 is communicatively connected to the control module 40.
Referring to fig. 2 to 6 of the drawings, a warning device 91 of an electronic seal according to an embodiment of the present invention is configured to respond to a warning signal. For example, when the human body sensing device 30 senses that anyone is too close (less than a preset distance) to 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 an audible/visual warning, so as to deter the electronic seal from being damaged.
