The above-mentioned sharp pulse is a signal generated by a piezoelectric thin film sensor subjected to an external force greater than a specified size and acting in a designated turn. The larger the external force, the shorter the action time, and the larger the amplitude of the sharp pulse generated. In real life, when a pet is hit by an abnormal impact, it will inevitably be transmitted to the pet wearing device. Therefore, the pet wearing device will inevitably collect a sharp pulse. Then, in the case of a sharp pulse, it can accurately determine whether the pet is abnormally impacted. collision.

The larger the external force, the shorter the action time, and the larger the amplitude of the sharp pulse generated. In real life, when a pet is hit by an abnormal impact, it will inevitably be transmitted to the pet wearing device. Therefore, the pet wearing device will inevitably collect a sharp pulse. Then, in the case of a sharp pulse, it can be judged whether the pet is hit by an abnormal impact. A basis for this.

Then, the pet's physiological signals, such as the pet's breathing rate, interest rate, etc., are determined by the micro-motion signal. It is also possible to judge whether or not the pet is hit by an abnormal impact by a sharp pulse or the like which is greatly changed in the jog signal. For example, in the designated time zone, when at least one sharp pulse occurs in the micro-motion signal, and the amplitude of the sharp pulse is greater than a preset threshold 吋, it is determined that the pet is impacted by an abnormal impact; or, in a designated day, when At least one sharp pulse occurs in the fretting signal, and the pet's arrhythmia is detected, and the pet is determined to be bumped by an abnormal impact. After the determination, the determination result is wirelessly transmitted to the corresponding terminal by the wireless transmission device, and the transmission of the determination result is generally only transmitted at the moment of the state change, that is, when the pet wearing device determines that the pet is attacked by the abnormal impact, the transmission determination is performed.

In real life, when a pet is hit by an abnormal impact, it will inevitably be transmitted to the pet wearing device. Therefore, the pet wearing device will inevitably collect a sharp pulse. Then, in the case of a sharp pulse, it can accurately determine whether the pet is abnormally impacted. collision. The specific threshold is set to be large, and how many sharp pulses are needed to be larger than the preset threshold. The empirical value can be obtained through a large number of experiments, and then substituted into a preset algorithm for calculation, thereby obtaining an accurate judgment result.

[0101] In another embodiment, the processor 200 acquires at least one sharp pulse of the micro-motion signal in the designated day, and detects the abnormal heart rate of the pet, and determines that the pet is hit by an abnormal impact. In the above-mentioned designated daytime, it refers to a period of time during the acquisition of the micro-motion signal, generally for the current engraving to advance to the designated day, for example, the current engraving advances for 10 seconds, 5 seconds, and the like. The above-mentioned sharp pulse is a signal generated by a piezoelectric thin film sensor subjected to an external force greater than a specified size and acting in a designated turn. The larger the external force, the shorter the action time, and the larger the amplitude of the sharp pulse generated. In real life, when a pet is hit by an abnormal impact, it will inevitably be transmitted to the pet wearing device, so the pet wearing device will inevitably collect a sharp pulse. Then, through the case of sharp pulses, it is possible to determine the most evidence of whether a pet is hit by an abnormal impact. When a pet is hit by an abnormal impact, it will inevitably produce a relative heart rate change. If the heart rate is increased, the pet's state may be abnormal. It may be just excited or scared. If the heart rate is slow, even if the heart rate stops, you can respond to the pet. Not good. Therefore, the state of the heart rate can also be used as a basis for judging whether a pet is hit by an abnormal impact. When the two judgments of the situation of the sharp pulse and the heart rate are combined, the accuracy of determining whether the pet is hit by the abnormal impact can be improved.

When the pet wearing device determines that the pet is attacked by an abnormal impact, the determination result is sent to the terminal, and the terminal holder is reminded to perform the rescue operation. Rationally, when the pet wearing device determines that the pet is not hit by an abnormal impact, the terminal holder is reminded that the pet is safe. Of course, the result of the pet wearing device determining that the pet is not attacked by the abnormal impact is not sent to the terminal, and is generally sent at the specified frequency, and the pet wearing device determines that the pet is attacked by the abnormal impact, and immediately sends the judgment result to the terminal. terminal.

The power module 700 supplies power to the devices, and the GPS module 600 acquires location information of the pet wear device. Wait.

[0106] In a specific embodiment, the pet wearing device is a collar, and a piezoelectric film sensor is disposed on the inner side of the ring, and when the pet wears the ring, the piezoelectric film is pressed against the part of the pet. Piezoelectric film sensing The device collects the pressure signal of the pet item and converts it into an electrical signal. After the electric signal is amplified by the amplifier, processed by a price comparator, etc., the pet's micro-motion signal is obtained. Then, the physiological signal of the pet, such as the respiratory rate and interest rate of the pet, is determined by the micro-motion signal. It is also possible to judge whether or not the pet is hit by an abnormal impact by a sharp pulse or the like which is greatly changed in the jog signal. For example, in the designated time zone, when at least one sharp pulse occurs in the micro-motion signal, and the amplitude of the sharp pulse is greater than a preset threshold 吋, it is determined that the pet is impacted by an abnormal impact; or, in a designated day, when At least one sharp pulse occurs in the fretting signal, and the pet's arrhythmia is detected, and the pet is determined to be bumped by an abnormal impact. After the determination, the determination result is wirelessly transmitted to the corresponding terminal by the wireless transmission device, and the transmission of the determination result is generally only transmitted at the moment of the state change, that is, when the pet wearing device determines that the pet is attacked by the abnormal impact, the transmission determination is performed. The result is to the terminal, reminding the terminal holder to perform the rescue, etc.; and the pet wearing device judges that the pet is not attacked by the abnormal impact, and the result is not sent to the terminal, and is generally sent at the specified frequency.
