Description

Technical Field

[0001] The present invention relates to the field of pet information technology, and in particular to a real-time determination method and device for a lost pet. Background Art

[0002] At present, pet anti-lost and anti-theft devices are mainly collars or implanted electronic chips. The collar integrates GPS (Global Positioning System) to receive satellite signals and is worn around the neck of the pet. The implanted electronic chip also integrates GPS function and is implanted in the pet's body for monitoring. The main principle is: when the device with integrated GPS module enters working mode, it starts to capture satellite signals above the pet. When receiving the satellite signal, the device not only obtains the location information of the satellite, but also calculates the distance between the pet and the satellite; when the device obtains three or more satellite signals, it can calculate the location of the pet through the location of these three satellites and the distance between the pet and these three satellites. When the GPS signal is found to be far away from the pet owner, a reminder is issued. However, GPS-based technology cannot distinguish whether the pet is lost or stolen, which affects the judgment of the pet owner. Summary of the invention

[0003] In view of the current difficulties in preventing pets from being lost or stolen, the present invention proposes a method for detecting pet loss based on real-time monitoring of GPS and motion posture. Through this method, it is possible to quickly determine whether the pet is actively lost or stolen, providing information and early warning for timely recovery of the pet.

[0004] A real-time determination method for a lost pet includes configuring a main controller and a transponder, installing the main controller and at least one transponder on the pet's limbs, activating the main controller and the transponder, and starting a real-time monitoring function, including the following steps: Step 1: The GPS unit of the main controller monitors and records the pet's movement trajectory in real time and calculates the movement distance; Step 2: The signal transmitting / receiving unit of the master controller sends a signal to multiple transponders at the same time, and the transponders reply to the master controller with a successfully received command; Step 3: Calculate the time of transmitting the signal and replying the command, and calculate the distance between the master controller and multiple transponders according to the time length to form distance data; Step 4: Calculate the pet's movement posture in unit time based on multiple sets of distance data in unit time; Step 5: Determine whether the pet is lost based on the pet's movement posture, combined with the pet's movement distance and movement trajectory. If the pet is lost, an alarm is sounded.

[0005] A device for determining whether a pet is lost comprises a main controller and one or more transponders, wherein the main controller and the transponders are arranged on the pet's limbs. The distance between the main controller and the multiple transponders is calculated according to the time of transmitting signals and replying instructions, and the movement posture of the pet in unit time is obtained according to the distance. Whether the pet is lost is determined according to the pet's movement posture, the pet's movement distance and the movement trajectory.

[0006] The beneficial effects of the present invention are: determining whether a pet is lost or stolen, sending warning information in time, and providing a way to find the pet. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0013] like Figure 1-2 As shown, the pet lost judgment device based on GPS and real-time monitoring of motion posture proposed by the present invention includes a main controller 10 and multiple transponders 20. In the embodiment of the present invention, 1 to 3 transponders are used as an example.

[0014] The main controller is arranged in a tough flexible webbing 30, which is generally made of PVC, nylon and other materials, including flexible webbing arranged on the limbs. The flexible webbing can be equipped with a rubber ring so that the flexible webbing can be worn on the pet's limbs.

[0015] The main controller 10 includes: a GPS unit 11, a mobile data communication unit 12, a voice playback unit 13, a signal transmitting / receiving unit 14, and an electronic safety lock 15, which can be arranged on a flexible circuit board in the flexible webbing, that is, the GPS unit, the mobile data communication unit, the voice playback unit, and the signal transmitting / receiving unit are arranged on the flexible circuit board and connected by wires.

[0016] GPS unit: used to locate the pet and determine the pet's movement distance and movement trajectory within a certain period of time.

[0017] Mobile data communication unit: used to transmit data with the pet owner's mobile phone, receive and send relevant pet information. The mobile data communication unit can be used through the communication products of mobile communication operators, such as 4G communication.

[0018] Voice playback unit: used to play pre-recorded voices to instruct pets to make corresponding actions. Voices are instructions that pets can understand, and pets need to be trained in advance.

[0019] Signal transmitting / receiving unit: can transmit and receive one or more signals such as radio frequency, ultrasound, infrared, near infrared, etc.

[0020] Electronic safety lock: The pet owner can unlock it with a password. If the electronic safety lock is cracked violently or the flexible webbing is damaged by external force, a warning signal will be sent to the pet owner. The electronic safety lock is set on the main controller and multiple transponders to prevent human damage.

[0021] The transponder 20 is set in the tough flexible webbing, integrating the signal transmitting / receiving unit 21 and the electronic safety lock 22. The signal transmitting / receiving unit and the electronic safety lock are integrated on the circuit board. The circuit board is placed in the flexible webbing after being treated with waterproof and dustproof. For example, a shell is added or a layer of waterproof glue is applied. A rubber ring is added so that it can be configured on the pet's limbs.

[0022] Signal transmitting / receiving unit: can transmit and receive one or more signals such as radio frequency, ultrasound, infrared, near infrared, etc.

[0023] Electronic safety lock: The pet owner can unlock it with a password. If the electronic safety lock is cracked by force or the flexible webbing is damaged by external force, a warning signal will be sent to the pet owner.

[0024] In an embodiment of the present invention, the pet anti-lost and anti-theft device and method based on real-time monitoring of GPS and motion posture technology implements the following process: Before implementing the method, the main controller and the transponder are installed in the flexible webbing, and the main controller and at least one transponder are installed on the limbs of the pet.

[0025] The pet owner enters the password through the electronic safety lock, unfastens the flexible webbing, and puts a main controller on the pet's left forelimb; and puts a transponder on the pet's left hind limb, right forelimb, and right hind limb respectively. The above wearing parts are only for explanation, and the pet owner can adjust the above wearing parts according to actual conditions. In order for the proposed anti-lost and anti-theft device to work properly, the pet needs to wear a main controller and at least one transponder.

[0026] like Figure 3 As shown, after the installation is complete, activate the main controller and transponder to turn on the real-time monitoring function for anti-lost and anti-theft.

[0027] The corresponding pet action command voice is input through the voice playback unit of the main controller, such as the voice commanding the pet to sit down or stay still. At the same time, the information exchange between the main controller and the pet owner's mobile phone is realized through the mobile data communication unit of the main controller. After the setting is completed, the pet owner can turn on the real-time monitoring function of anti-lost and anti-theft.

[0028] Step 1: The GPS unit of the main controller monitors and records the pet's movement trajectory in real time and calculates the movement distance.

[0029] And every 1 minute (the time can be set according to the actual situation, such as 2 minutes, 5 minutes, etc.) according to the pet's movement trajectory, calculate the pet's movement distance within 1 minute.

[0030] Step 2: The signal transmitting / receiving unit of the main controller sends a signal to multiple transponders at the same time. The transponders reply to the main controller with a successfully received instruction. The time of transmitting the signal and replying the instruction is calculated. The distance between the main controller and the multiple transponders is calculated according to the time length to form distance data.

[0031] When the GPS unit of the main controller monitors and records the movement trajectory of the pet in real time, the signal transmitting / receiving unit of the main controller simultaneously sends one or more signals such as radio frequency, ultrasound, infrared, near infrared, etc. to N transponders (i.e. transponder 1, transponder 2, transponder 3) every 0.5 seconds (it can also be set to other values). After receiving the signal transmitted by the main controller, the transmitting / receiving unit of the transponder replies to the main controller with a successfully received command.

[0032] After the signal transmitting / receiving unit of the main controller receives the reply from the transponder, it calculates the time required for the main controller to transmit the signal and receive the reply from the transponder, and calculates the distance between the main controller and transponder 1, transponder 2, and transponder 3 based on the time length.

[0033] Step 3: Calculate the pet's movement posture within a unit time based on multiple sets of distance data within a unit time.

[0034] In 1 minute, when the distance data is acquired every 0.5 seconds, a total of 120×3=360 sets of data can be obtained. Based on the above 360 ​​sets of data, the movement posture of the pet in this 1 minute is calculated.

[0035] like Figure 4 As shown, in the embodiment of the present invention, the calculation method of the pet's motion posture is as follows: S31: Determine the input and output of the motion posture recognition model.

[0036] The input of the motion posture recognition model is 360 sets of data; the output of the motion posture recognition model is in three forms: the pet is still, the pet's motion posture changes irregularly, and the pet's motion posture changes regularly.

[0037] S32: Establish a motion posture recognition model using a convolutional neural network algorithm.

[0038] The motion posture recognition model is implemented using a convolutional neural network algorithm, which includes three convolutional sublayers and three fully connected layers. Each convolutional sublayer contains a convolutional layer, a batch normalization layer, a maximum pooling layer, a signal discarding layer, etc.

[0039] S33: By acquiring data of the pet in different states, the pet's motion posture is identified using a motion posture recognition model.

[0040] Step 4: Calculate the pet's movement posture according to the above steps, and combine the pet's movement distance and movement trajectory to achieve pet anti-lost and anti-theft protection, and determine whether the pet is lost.

[0041] like Figure 3-5 As shown, in the embodiment of the present invention, the specific method for determining whether a pet is lost is as follows: In the first case, when the pet's movement distance is greater than the set threshold, the movement trajectory deviates from the specified location (such as the owner's house) by more than the set threshold, and the pet's movement posture is recognized as the pet being stationary, it indicates that the pet is very likely to have been stolen. The main controller immediately sends a pet theft risk to the pet owner's mobile phone, and sends the pet's current location information to the mobile phone in real time, reminding the pet owner to call the police immediately.

[0042] In the second case, when the pet's movement distance is greater than the set threshold, the movement trajectory deviates from the specified position by more than the set threshold, and the pet's movement posture is recognized as changing irregularly, indicating that the pet is likely to have been stolen, the main controller immediately sends a message to the pet owner's mobile phone indicating that the pet is at risk of being stolen, reminding the pet owner to pay close attention to the pet's location information.

[0043] The third case is when the pet's movement distance is greater than the set threshold, and the movement trajectory deviates from the specified position by more than the set threshold, but the pet's movement posture is recognized as changing regularly, indicating that the pet is at risk of being lost, the main controller immediately sends a message to the pet owner's mobile phone that the pet is at risk of being lost. After receiving the prompt, the pet owner can activate the voice playback unit of the main controller by sending a command, commanding the pet to stay still, to prevent the risk of the pet being lost from further expanding, and retrieve the pet based on the pet's movement trajectory.

[0044] The fourth case is when the pet's movement distance is less than the set threshold, the movement trajectory deviates from the specified location (such as the owner's house) by less than the set threshold, and the pet's movement posture changes regularly or is stationary, it indicates that the pet is not at risk of being stolen or lost.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
