FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
Reference will now be made in further detail to the accompanying drawings.
As shown in fig. 1
A child anti-theft system comprises an intelligent bracelet worn on a child hand, wherein the intelligent bracelet comprises a human body resistance detector, a humidity sensor, a heartbeat sensor, a GPS (global positioning system) positioner, a face capture camera and a GPS positioner, which are mounted on a child cap, and the intelligent bracelet detection has a first detection mode and a second detection mode;
the first detection mode is a detection mode when the arms of the children are dry, and the second detection mode is a detection mode when the arms of the children are wet;
the intelligent bracelet detects the skin resistance of the child, and the skin resistance is smaller than the set threshold value of the skin resistance, so that whether the child contacts with a person is judged;
the heartbeat inductor judges whether the device is in a tension state or not through the change of heartbeat frequency;
the face capturing camera is a 360-degree camera, captures surrounding faces and sends the captured faces to the central processing unit to compare the faces and judge whether the faces are in the environment of being turned or not.
When the humidity of the skin of the child is detected to be 0% -30% by the humidity sensor, the skin is in a dry state, the first detection mode is started, the value detected for the first time is a first skin resistance value, and the skin resistance value detected for the next time is a second skin resistance value;
the resistance value of the human body resistor is 2000-20 megaohms under the condition of dry skin, when a person touches a detected person, the cross section area of the human body resistor of the detected person is increased, and the two large resistors are connected in parallel, so that the resistance value is far smaller than the resistance value without touching;
the first skin resistance value is used as a set threshold value, the first skin resistance value is larger than a second skin resistance value, when the percentage of the second skin resistance value divided by the first skin resistance value is larger than 10% and smaller than 50%, it is judged that the child and the person are in body contact, and when the second skin resistance value is larger than the first skin resistance value and is the first skin resistance value, the second skin resistance value is detected again;
when the humidity of the skin of the child is detected to be 31% -80% by the humidity sensor, the skin is in a wet state, the second detection mode is started, the value detected for the first time is a first skin resistance value, and the skin resistance value detected for the next time is a second skin resistance value;
when the human body skin is in a wet state, the resistance value of the human body can be reduced to 1000-2000 ohms, and when another extremely large human body resistor is contacted, the measured second resistance value can be infinitely close to the first skin resistance value;
the first skin resistance value is used as a set threshold value, the value of the first skin resistance value is larger than a second skin resistance value, the value obtained by dividing the second skin resistance value by the first skin resistance value is larger than 90% and smaller than 1, when the second skin resistance value is larger than the first skin resistance value and smaller than 2000 ohms, the second skin resistance value is changed into the first skin resistance value, and the second skin resistance value is detected again.
The heartbeat sensor acquires the heartbeat frequency of the child, the judgment standard is that the heartbeat frequency in the first minute is 60-80 minutes, the heartbeat frequency in the second minute is increased to 100-150 minutes, and the heartbeat frequency in the third minute continues to rise or does not fall, the central processing unit judges that the child is in a tension state, if the child is not in the tension state, whether the child contacts with a person is detected again until the child is in the tension state.
The face capturing camera is a small camera hidden in a child cap, the camera is a 360-degree camera, a panoramic picture is shot to capture a face of the child cap, the face is sent to the central processing unit, a face spectrogram of a parent of the child is stored in the central processing unit, face comparison is carried out, if the face spectrogram is successfully compared with the stored face spectrogram of the parent, the fact that the parent is nearby is indicated, the system jumps back to a stage of detecting whether the parent contacts with the child again, and if the face spectrogram is not successfully compared with the stored face spectrogram, GPS positioning is started to send positioning to parents of the child in real time.
GPS locator uses GPS locator send position on the bracelet as the owner, works as when human resistance detector detects resistance =0 (resistance is infinitely great), then central processing unit judges the hand
When the ring is removed, a GPS locator on the hat is started to send the position in real time.
