Description

Technical Field

[0001] This application relates to the technical field of intelligent pet monitoring, and in particular to a pet safety monitoring system and method based on wireless signal connection. Background Technology

[0002] As people's living standards improve, pets are gradually becoming important family members, and the need for pet safety monitoring is becoming increasingly prominent. Pet positioning devices, as a core tool to prevent pets from getting lost, have been widely used. Existing pet positioning devices mainly rely on satellite positioning (such as GPS and Beidou) combined with mobile networks (such as 4G and NB-IoT) to report their location. Although this type of solution can provide location information in wide-area outdoor scenarios, it has many technical shortcomings and cannot meet users' core needs for close-range pet status monitoring and low power consumption.

[0003] However, satellite positioning modules consume a lot of power. To ensure real-time location monitoring, the device needs to frequently activate the satellite positioning module and report its location, resulting in poor battery life and frequent charging, which is inconvenient for users. Secondly, in indoor environments or under building obstructions, satellite signal strength is weak, which can easily lead to inaccurate positioning or even positioning failure, making it impossible to achieve full-scene monitoring. Furthermore, existing solutions can only provide the pet's geographical location information and cannot provide intuitive status prompts in close-range scenarios, such as whether the pet is near the owner or within the control range of the leash, making it difficult for users to quickly determine the pet's immediate safety status. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a pet safety monitoring system and method based on wireless signal connection.

[0005] Firstly, this application provides a pet safety monitoring system based on wireless signal connection, employing the following technical solution: A pet safety monitoring system based on wireless signal connection includes a pet positioning terminal, a detachable beacon, and a mobile terminal; The pet positioning terminal includes a first wireless communication module, a satellite positioning module, a first control unit, and a first alarm module; The detachable beacon includes a second wireless communication module, a second control unit, and a second alarm module. The detachable beacon has a fixing structure for fixing to the pet leash and establishing a wireless connection with the pet positioning terminal. The mobile terminal is equipped with a pet monitoring application for communicating with the pet location terminal; The first control unit is configured to monitor wireless signal characteristic parameters from the detachable beacon, the wireless signal characteristic parameters including signal strength, signal stability, and signal attenuation rate; When the signal strength indicates that the pet positioning terminal is within the vicinity of the detachable beacon, the satellite positioning module is controlled to enter a sleep or low-power mode and a first status information is sent to the mobile terminal. When the signal strength is lower than the preset separation threshold or the connection is lost, the system controls the first alarm module to be triggered and / or sends a separation alarm message to the mobile terminal, and wakes up the satellite positioning module to obtain the current location information and report it.

[0006] Optionally, the second control unit of the detachable beacon is configured to trigger the second alarm module to perform an audible and visual alarm when the wireless connection with the pet positioning terminal is disconnected, or when the wireless beacon proximity confidence score corresponding to the wireless signal characteristic parameters reaches a preset abnormal threshold.

[0007] Optionally, the fixing structure is one or more combinations of buckles, clips, Velcro, or loop straps, and the fixing structure is integrally formed with the shell of the detachable beacon to achieve detachable fixing of the detachable beacon and the pet leash.

[0008] Optionally, the wireless beacon proximity confidence score The methods for obtaining it include: ; ; ; in, for The minimum signal strength threshold at time [time]. Data collection time interval The average signal strength threshold within the range, Data collection time interval Total number of data collections within the scope. This is the sequence number of the number of times the sample was collected. Given the current signal strength, The signal fluctuation value is calculated using the standard deviation formula. For signal attenuation rate, , These are the preset weighting coefficients for the corresponding items.

[0009] Optionally, the minimum signal strength threshold is dynamically configured and set in a positive correlation with the signal fluctuation value.

[0010] Optionally, the pet monitoring application on the mobile terminal is also configured to provide a user interface for users to register and name the wearing location or item identifier for at least one of the detachable beacons, the location or item identifier including leash, home room, and to support group management of multiple detachable beacons.

[0011] Optionally, the pet positioning terminal also includes a mobile network module for remote communication with the mobile terminal. The satellite positioning module supports both GPS and BeiDou positioning modes and can automatically switch positioning modes according to the environmental signal strength.

[0012] A pet safety monitoring method based on wireless connection signals includes the following steps: The detachable beacon is fixed to the pet leash using a fixing structure, and then paired and associated with the pet positioning terminal through a pet monitoring application on a mobile terminal. The pet positioning terminal continuously monitors the wireless signal characteristic parameters of the associated detachable beacon through the first wireless communication module. The wireless signal characteristic parameters include signal strength, signal stability, and signal attenuation rate, and performs collaborative filtering on each parameter. When the signal characteristic parameters are detected to be stable within the nearby range, it is determined that the pet is in a safe following state. The satellite positioning module is put into sleep mode, and a safe following status prompt is sent to the user's mobile terminal. When the signal characteristic parameters are detected to indicate separation, a separation event is determined to have occurred. The local alarms of the detachable beacon and the pet positioning terminal are triggered in tandem, and a separation alarm notification is pushed to the user's mobile terminal. After the separation event occurs, the pet positioning terminal activates the satellite positioning module to obtain a precise location and reports the location information to the mobile terminal through the mobile network module.

[0013] Optionally, a beacon location registration step may be included before the beacon association step: The user enters the expected location or item identification information of the detachable beacon in the pet monitoring application on the mobile terminal. The pet positioning terminal realizes the distinguishing monitoring of the pet's status in multiple scenarios based on the signal characteristic parameters of the detachable beacon with different identifications. The coordinated triggering of local alarms includes: the pet positioning terminal triggers the first alarm module to perform an audible and visual alarm; at the same time, the detachable beacon independently triggers the second alarm module to perform an audible and visual alarm after detecting a connection abnormality, and the alarm frequencies of the two are different to distinguish them.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. This application adopts a comprehensive monitoring method of wireless signal characteristic parameters to replace the existing single wireless signal strength monitoring. Multi-dimensional parameter collaborative judgment, combined with dynamic comprehensive threshold calculation, can not only filter out signal fluctuations caused by environmental interference, but also accurately capture signal changes caused by pet separation, greatly improving the accuracy of status judgment and reducing false alarm rate. By combining the detachable beacon with the pet leash, the application scenario of wireless connection signal is expanded from fixed home environment to outdoor mobile scenario. The intelligent power consumption management method of controlling the satellite positioning module to sleep in safe following state and waking up the satellite positioning module in separation state effectively reduces the overall power consumption of the device, extends the battery life, and solves the problems of high power consumption and poor battery life of existing satellite positioning devices.

[0015] 2. This application utilizes a pet positioning terminal and a detachable beacon for coordinated local audible and visual alarms, combined with remote alarm push notifications from a mobile terminal, to form a multi-dimensional alarm mechanism. Simultaneously, the satellite positioning module promptly activates and reports the location, significantly improving the response speed and retrieval probability after a pet becomes uncontrollable, thus solving the problem of untimely alarm response in existing solutions. The detachable beacon's fixing structure is adaptable to different leash sizes, and the mobile terminal supports group management of multiple beacons, enhancing the device's versatility and user experience. The overall solution is simple in structure and easy to implement, requiring no complex hardware modifications. It can be industrialized based on existing mature wireless communication and satellite positioning technologies, possessing strong promotional value. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the pet safety monitoring system in this application. Detailed Implementation

[0017] The embodiments of this application are described in detail below, and examples of the embodiments are shown in the accompanying drawings.

[0018] In the description of this specification, the references to "certain embodiments," "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples" refer to specific features, structures, materials, or characteristics described in connection with the described embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0019] In this application, the signal connection between the pet positioning terminal and the detachable beacon can be wirelessly connected using any one of the following technologies: Bluetooth, WIFI, LoRa, Sigfox, RFID, Zigbee, UWB, and Starflash technology.

[0020] In this embodiment of the application, taking Bluetooth connection as an example, a pet safety monitoring system based on wireless signal connection is disclosed, with reference to... Figure 1 It includes a pet locator, a detachable beacon, and a mobile terminal. The specific hardware configuration is as follows: Pet positioning terminal: Features a waterproof casing, compatible with pet collars, with an IP67 waterproof rating to prevent damage from outdoor rain or pet water play. Internally, it integrates a first wireless communication module (in this embodiment, a BLE5.2 module is used, with a communication distance of 10-30m and support for low-power mode), a satellite positioning module (supporting GPS / BeiDou dual-mode positioning, positioning accuracy ≤5m, sleep power consumption ≤10μA, and operating power consumption ≤50mA), a first control unit (using an STM32L4 series low-power microcontroller with an 80MHz main frequency, responsible for the coordinated control and algorithm calculation of various modules, capable of collecting, processing, and comprehensively judging wireless signal characteristic parameters), a first alarm module (including a miniature buzzer and LED indicator; the buzzer volume is ≥80dB, the LED indicator is red, and the alarm frequency is 2 times / second), and a mobile network module (using Cat). The device consists of one module (supporting remote data transmission, low power consumption and wide coverage) and a lithium battery (700mAh capacity, supporting standby time of 3-6 months); each module is electrically connected to the first control unit and is powered by the lithium battery. The first control unit can dynamically adjust the power supply mode of each module according to the device's working status to further reduce power consumption.

[0021] Detachable beacon: Features a miniaturized waterproof housing measuring 20mm×15mm×8mm for easy attachment to a leash; internally integrates a second wireless communication module (matching the first wireless communication module of the pet positioning terminal, also using a BLE5.2 module, with power consumption ≤5μA in low-power mode), a second control unit (using an ATtiny13 series microcontroller to control the detachable beacon's operating status and monitor wireless connection status and signal characteristic parameters), a second alarm module (including a miniature buzzer and LED indicator; the buzzer volume is ≥70dB, the LED indicator is blue, and the alarm frequency is 1 time / second, distinguishable from the first alarm module), and a button battery (200mAh capacity, standby time 6-12 months); the fixing structure uses a spring clip, integrally molded with the housing, with a clamping range of 5-20mm, adaptable to pet leashes of different thicknesses, achieving a secure fixation of the detachable beacon to the leash and facilitating easy removal and replacement.

[0022] Mobile terminal: Uses a smartphone (supporting Android 8.0 and above or iOS 12.0 and above) with a pet monitoring application installed. This application supports device binding, beacon registration and naming, parameter configuration (high threshold range, preset time period, fluctuation threshold, attenuation threshold, weight coefficient, etc.), status viewing, alarm reception, location tracking and trajectory playback, etc. The mobile terminal establishes remote communication with the pet positioning terminal through the Cat. 1 network to achieve data interaction.

[0023] System Deployment Process: Users first open the pet monitoring application on their mobile terminal, complete account registration and login, and then enter the beacon registration interface. They then enter the identification information for the detachable beacon, naming it "Outing Leash". The user opens the spring clip of the detachable beacon and clamps it 10cm below the handle of the pet leash, ensuring a secure fit to prevent it from falling off during pet activity. The user then turns on the pet positioning terminal and places it on the pet's collar, ensuring it fits snugly around the pet's neck without hindering movement. A pairing request is initiated in the mobile terminal application. Upon receiving the request, the first wireless communication module of the pet positioning terminal pairs with the second wireless communication module of the detachable beacon, establishing a stable wireless connection. After successful pairing, the mobile terminal application displays "Device Binding Successful," completing the system deployment. At this point, the system enters normal monitoring mode, and the pet positioning terminal begins continuously collecting the wireless signal characteristic parameters of the detachable beacon.

[0024] The specific steps of the pet safety monitoring method based on the above system are as follows: all parameters are pre-configured through the mobile terminal application: sliding window length N=8, data collection time interval... For 2 seconds, weighting coefficient , The values ​​are 0.6 and 0.4 respectively, the separation determination preset time is 3 seconds, the location reporting frequency is once every 3 seconds, and the wireless beacon proximity reliability score is... The methods for obtaining it include: ; ; ; in, for The minimum signal strength threshold at time [time]. Data collection time interval The average signal strength threshold within the range, Data collection time interval Total number of data collections within the scope. This is the sequence number of the number of times the sample was collected. Given the current signal strength, The signal fluctuation value is calculated using the standard deviation formula. This represents the signal attenuation rate.

[0025] Step 1: Beacon Location Registration. Users enter the identification information of the detachable beacon on the beacon registration interface of the mobile application, naming it "Outing Leash," and complete the registration. The application then synchronizes this identification information to the pet tracking device for easy identification of its status later.

[0026] Step 2: Beacon Association. Secure the detachable beacon to the designated position on the pet leash using a spring clip. Turn on the pet tracking terminal. In the mobile application, click "Pair Device" to initiate a Bluetooth pairing request. After receiving the request, the first wireless communication module of the pet tracking terminal pairs with the second wireless communication module of the detachable beacon, establishing a wireless connection. Once successfully associated, the pet tracking terminal continuously collects the wireless signal characteristic parameters (signal strength, signal stability, signal attenuation rate) of the detachable beacon. In this step, the minimum signal strength threshold can also be set to a dynamic configuration, positively correlated with signal fluctuation within a reasonable range, thus reducing the possibility of false alarms in situations with significant obstruction and interference. Step 3: Proximity Monitoring. The first control unit of the pet positioning terminal controls the first wireless communication module to collect the raw value of the wireless signal strength of the detachable beacon at a frequency of 1 time / second, and simultaneously acquire the signal fluctuation value and signal attenuation rate; Step 4: Security Status Assessment and Notification. The first control unit will perform a collaboratively processed wireless beacon proximity confidence score. The confidence score is compared with the corresponding preset threshold. When a wireless beacon is detected, the confidence score is determined. If the pet remains in a safe following state for 5 seconds without changing the specified value (which can be configured by the user during initialization), the first control unit sends a sleep command to the satellite positioning module, controlling the satellite positioning module to enter sleep mode. Only the first wireless communication module maintains low-power operation. At the same time, the first control unit sends a safe following status prompt to the mobile terminal through the mobile network module. After receiving the prompt, the mobile terminal application displays "My pet is near the leash and is in a safe state" on the interface, accompanied by a green icon, allowing the user to intuitively know the pet's status.

[0027] Step 5: Separation Detection and Alarm. During outdoor walks, if a pet breaks free of its leash, causing a rapid increase in the distance between the pet tracking device and the detachable beacon, the wireless beacon proximity reliability score will be activated. When the value exceeds a preset threshold, a separation event is determined to have occurred. At this time, the first control unit immediately triggers the first alarm module, the red LED indicator flashes (2 times / second), and the buzzer sounds an alarm (80dB). Simultaneously, the first control unit pushes a separation alarm notification to the mobile terminal via the mobile network module, with the message "Warning! Your pet has broken free of its leash. Please check its location." Upon receiving the notification, the mobile terminal rings an alarm, and an alarm pop-up appears on the application interface. At the same time, the second control unit of the detachable beacon detects an abnormal connection with the pet positioning terminal (abnormal signal characteristic parameters) and immediately triggers the second alarm module, the blue LED indicator flashes (1 time / second), and the buzzer sounds an alarm (70dB), alerting passersby to the abnormality and requesting assistance in managing the pet.

[0028] Step 6: Location Reporting. Upon detecting a separation event, the first control unit sends a wake-up command to the satellite positioning module, activating it. The satellite positioning module detects a strong GPS signal in the environment and automatically switches to GPS positioning mode, quickly acquiring the current latitude and longitude coordinates (positioning accuracy ≤ 5m). It then continuously reports the location information to the mobile terminal via the mobile network module at a frequency of once every 3 seconds. After receiving the location information, the mobile terminal application displays the pet's movement trajectory on an electronic map in real time, simultaneously marking the current location. The user can quickly navigate to find the pet using the map navigation. When the user finds the pet, they bring the pet positioning terminal close to the detachable beacon again. The wireless connection is restored, and after all signal characteristic parameters return to the preset normal range and stabilize for 10 seconds, the system automatically clears the alarm, and the satellite positioning module re-enters sleep mode, resuming low-power operation.

[0029] In this embodiment, the user can deploy an additional detachable beacon in the home environment, registered and named "Living Room Fixed Beacon," and fix it to the living room wall to achieve multi-scenario monitoring of pets indoors and outdoors. When the pet is active in the living room, the pet positioning terminal detects that the signal characteristic parameters of the "Living Room Fixed Beacon" are stable within the preset normal range, determines that the pet is in the safe area of ​​the living room, and also controls the satellite positioning module to go into sleep mode, sending a "Pet is in the living room" status prompt to the mobile terminal. When the pet leaves the living room, the signal characteristic parameters become abnormal, the system triggers an alarm and wakes up the satellite positioning module to report the location, achieving seamless indoor and outdoor monitoring.

[0030] Meanwhile, users can adjust relevant parameters through the mobile application according to the actual usage environment: in environments with strong signal interference (such as dense residential areas or near shopping malls), the sliding window length N can be adjusted to 10, and the weighting coefficient can be adjusted accordingly. Adjusting the weighting to 0.7 increases the determination weight for signal stability and reduces the false alarm rate. In open outdoor environments, the sliding window length N can be adjusted to 5, and the weighting coefficient can be adjusted accordingly. The value was adjusted to 0.5 to increase the weight of the signal attenuation rate determination and improve the sensitivity of the separation determination. Through flexible parameter configuration, the system can be adapted to different usage scenarios, further improving the reliability of monitoring.

[0031] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
