一种超声防丢追踪器及***Ultrasonic anti-lost tracker and system 技术领域Technical Field
本实用新型涉及一种超声防丢追踪器及***，属于定位技术领域。The utility model relates to an ultrasonic anti-lost tracker and a system, belonging to the technical field of positioning.
背景技术Background technique
2021年4月21日，苹果在2021春季新品发布会上推出了一款全新的防丢追踪器(AirTag)，不同于传统的蓝牙防丢追踪器，增加了近距离精确查找功能：苹果在AirTag中内置了UWB模块，通过AirTag中的UWB模块与手机中的UWB模块交互，实现测距，获得距离信息；而为了获得指向信息，苹果调用了手机的摄像头与传感器，利用局部视觉里程计算法与IMU，配合UWB获得的距离信息，实现坐标点的估算，从而获得指向，实现了可视化的近距离查找。On April 21, 2021, Apple launched a new anti-lost tracker (AirTag) at the 2021 Spring New Product Launch Conference. Unlike traditional Bluetooth anti-lost trackers, it has added a close-range precise search function: Apple has built-in a UWB module in AirTag, and the UWB module in AirTag interacts with the UWB module in the mobile phone to achieve ranging and obtain distance information; in order to obtain pointing information, Apple calls on the camera and sensors of the mobile phone, uses local visual mileage calculation method and IMU, and cooperates with the distance information obtained by UWB to estimate the coordinate points, thereby obtaining pointing and realizing visual close-range search.
相对于传统蓝牙防丢追踪器，例如：华为于2022年推出的HaiweiTag，就是一种经典的蓝牙防丢追踪器，其搭载的蓝牙模块与手机蓝牙配对后，能够根据蓝牙信号强弱判断距离远近，从而给出距离近/远的结果，然后利用蜂鸣器提示寻找。传统蓝牙防丢追踪器的缺点显而易见，并不能向用户提供一个可视化的方向及距离，用户无法判断防丢追踪器在何方，近距离查找能力差。Compared with traditional Bluetooth anti-lost trackers, for example: HaiweiTag launched by Huawei in 2022 is a classic Bluetooth anti-lost tracker. After the Bluetooth module is paired with the mobile phone Bluetooth, it can judge the distance according to the strength of the Bluetooth signal, thereby giving a result of near/far distance, and then use the buzzer to prompt the search. The shortcomings of traditional Bluetooth anti-lost trackers are obvious. They cannot provide users with a visual direction and distance. Users cannot judge where the anti-lost tracker is, and the close-range search capability is poor.
虽然苹果的防丢追踪器能够给出可视化的信息，但是也并非尽善尽美，首先，为了实现测距，需要在Tag和手机中分别搭载UWB模块，Tag成本大幅上升，其次，如果对摄像头进行遮挡或使用虚假背景，即无法得到精确的指向信息，最后，如果用户携带手机不作移动，完全无法获得指向信息。Although Apple's anti-lost tracker can provide visual information, it is not perfect. First, in order to achieve ranging, UWB modules need to be installed in the tag and the mobile phone respectively, which greatly increases the cost of the tag. Secondly, if the camera is blocked or a false background is used, accurate pointing information cannot be obtained. Finally, if the user carries the mobile phone without moving, no pointing information can be obtained at all.

具体实施方式Detailed ways
实施例1：一种超声防丢追踪器，参照附图1～4，包括集成于壳体1中的的一个超声发射单元4、一个超声接收单元5、处理器2、蓝牙模块6和电池3，超声发射单元4、超声接收单元5、处理器2和蓝牙模块6分别通过线路与处理器2连接，这里，超声发射单元4和超声接收单元5与处理器的连接之间还具有数模转换器等元器件，实现处理器驱动超声发射单元4发出超声信号和超接收单元5接收超声信号的功能，实现的电路为现有技术，不做赘述。使用时，处理器2驱动蓝牙模块6持续发出蓝牙广播信号，便于用户携带的智能设备(手机)扫描找到对象。而电池3用于为超声防丢追踪器中所有的用电元器件供电。Embodiment 1: An ultrasonic anti-lost tracker, referring to Figures 1 to 4, includes an ultrasonic transmitting unit 4, an ultrasonic receiving unit 5, a processor 2, a Bluetooth module 6 and a battery 3 integrated in a housing 1. The ultrasonic transmitting unit 4, the ultrasonic receiving unit 5, the processor 2 and the Bluetooth module 6 are respectively connected to the processor 2 through lines. Here, there are also components such as digital-to-analog converters between the connection between the ultrasonic transmitting unit 4 and the ultrasonic receiving unit 5 and the processor, so as to realize the functions of the processor driving the ultrasonic transmitting unit 4 to emit ultrasonic signals and the ultrasonic receiving unit 5 to receive ultrasonic signals. The circuit implemented is the prior art and will not be described in detail. When in use, the processor 2 drives the Bluetooth module 6 to continuously emit Bluetooth broadcast signals, so that the smart device (mobile phone) carried by the user can scan and find the object. The battery 3 is used to power all electrical components in the ultrasonic anti-lost tracker.
防丢追踪器的超声发射单元4发出超声定位信号，被手机的两个mic收到，实现角度解算，而手机与防丢追踪器的超声信号交互实现距离解算，从而获得距离信息和指向信息，实现近距离精确指引。其中，超声发射单元4为扬声器，超声接收单元5为麦克风。The ultrasonic transmitting unit 4 of the anti-lost tracker sends out an ultrasonic positioning signal, which is received by the two microphones of the mobile phone to achieve angle resolution, and the ultrasonic signal interaction between the mobile phone and the anti-lost tracker realizes distance resolution, thereby obtaining distance information and direction information, and achieving close-range precise guidance. Among them, the ultrasonic transmitting unit 4 is a speaker, and the ultrasonic receiving unit 5 is a microphone.
虽然超声信号可以穿过壳体1，但是壳体1对超声信号具有强衰减作用，会使超声信号传播距离变短、信号强度变弱，不利于长距离精确查找。因此，为了避免壳体1影响超声信号的收发，在壳体上设置有一透音区11，这里透音区11为透音孔，一个透音区11可包含多个透音孔，透音孔孔径不大于1mm。Although the ultrasonic signal can pass through the shell 1, the shell 1 has a strong attenuation effect on the ultrasonic signal, which will shorten the propagation distance of the ultrasonic signal and weaken the signal strength, which is not conducive to long-distance accurate search. Therefore, in order to prevent the shell 1 from affecting the transmission and reception of ultrasonic signals, a sound-transmitting area 11 is provided on the shell, where the sound-transmitting area 11 is a sound-transmitting hole, and one sound-transmitting area 11 may include multiple sound-transmitting holes, and the aperture of the sound-transmitting hole is not greater than 1 mm.
同时，将超声发射单元4和超声接收单元5安装在透音区11出，一个透音区11与一个超声发射单元4或一个超声接收单元5对应，以便超声发射单元4能够通过透音区11直接将超声信号传出壳体1，及超声接收单元5能够收到直达超声信号。At the same time, the ultrasonic transmitting unit 4 and the ultrasonic receiving unit 5 are installed in the sound-transmitting area 11, and one sound-transmitting area 11 corresponds to one ultrasonic transmitting unit 4 or one ultrasonic receiving unit 5, so that the ultrasonic transmitting unit 4 can directly transmit the ultrasonic signal out of the shell 1 through the sound-transmitting area 11, and the ultrasonic receiving unit 5 can receive the direct ultrasonic signal.
为了避免超声防丢追踪器的超声接收单元5被自身的超声发射单元4发出的超声信号影响，将超声接收单元5安装至对应透音区11后，在壳体1内部安装上屏蔽腔14将超声接收单元5包覆，这里，屏蔽腔14为金属材质，从而屏蔽超声防丢追踪器的超声发射单元4发出的超声信号。In order to prevent the ultrasonic receiving unit 5 of the ultrasonic anti-lost tracker from being affected by the ultrasonic signal emitted by its own ultrasonic transmitting unit 4, after the ultrasonic receiving unit 5 is installed in the corresponding sound-transmitting area 11, a shielding cavity 14 is installed inside the shell 1 to cover the ultrasonic receiving unit 5. Here, the shielding cavity 14 is made of metal, thereby shielding the ultrasonic signal emitted by the ultrasonic transmitting unit 4 of the ultrasonic anti-lost tracker.
另外，超声发射单元4还能在处理器2的驱动下发出可听声，产生蜂鸣提示效果。In addition, the ultrasonic transmitting unit 4 can also emit an audible sound under the drive of the processor 2 to produce a buzzing prompt effect.
实施例2：一种防丢追踪器，参照附图1～4，包括集成于壳体1中的的一个超声发射单元4、两个超声接收单元5、处理器2、蓝牙模块6和电池3，超声发射单元4、超声接收单元5、处理器2和蓝牙模块6分别通过线路与处理器2连接，这里，超声发射单元4和超声接收单元5与处理器的连接之间还具有数模转换器等元器件，实现处理器驱动超声发射单元4发出超声信号和超接收单元5接收超声信号的功能，实现的电路为现有技术，不做赘述。使用时，处理器2驱动蓝牙模块6持续发出蓝牙广播信号，便于用户携带的智能设备(平板)扫描找到对象。而电池3用于为超声防丢追踪器中所有的用电元器件供电。Embodiment 2: An anti-lost tracker, referring to Figures 1 to 4, includes an ultrasonic transmitting unit 4, two ultrasonic receiving units 5, a processor 2, a Bluetooth module 6 and a battery 3 integrated in a housing 1. The ultrasonic transmitting unit 4, the ultrasonic receiving unit 5, the processor 2 and the Bluetooth module 6 are respectively connected to the processor 2 through lines. Here, there are also components such as digital-to-analog converters between the connection between the ultrasonic transmitting unit 4 and the ultrasonic receiving unit 5 and the processor, so as to realize the functions of the processor driving the ultrasonic transmitting unit 4 to emit ultrasonic signals and the ultrasonic receiving unit 5 to receive ultrasonic signals. The circuit implemented is the prior art and will not be described in detail. When in use, the processor 2 drives the Bluetooth module 6 to continuously emit Bluetooth broadcast signals, so that the smart device (tablet) carried by the user can scan and find the object. The battery 3 is used to power all electrical components in the ultrasonic anti-lost tracker.
平板发出超声定位信号，被超声防丢追踪器的两个mic收到，实现角度解算，而平板与超声防丢追踪器的超声信号交互实现距离解算，从而获得距离信息和指向信息，实现近距离精确指引。其中，超声发射单元4为压电陶瓷片，超声接收单元5为麦克风。The tablet sends out an ultrasonic positioning signal, which is received by the two microphones of the ultrasonic anti-lost tracker to achieve angle resolution, and the ultrasonic signal interaction between the tablet and the ultrasonic anti-lost tracker achieves distance resolution, thereby obtaining distance information and direction information, and achieving close-range precise guidance. Among them, the ultrasonic transmitting unit 4 is a piezoelectric ceramic piece, and the ultrasonic receiving unit 5 is a microphone.
虽然超声信号可以穿过壳体1，但是壳体1对超声信号具有强衰减作用，会使超声信号传播距离变短、信号强度变弱，不利于长距离精确查找。因此，为了避免壳体1影响超声信号的收发，在壳体上设置有一透音区11，这里透音区11由超声低衰减材料制成，例如eptfe膜。Although the ultrasonic signal can pass through the shell 1, the shell 1 has a strong attenuation effect on the ultrasonic signal, which will shorten the propagation distance of the ultrasonic signal and weaken the signal strength, which is not conducive to long-distance accurate search. Therefore, in order to prevent the shell 1 from affecting the transmission and reception of ultrasonic signals, a sound-transmitting area 11 is provided on the shell, and the sound-transmitting area 11 is made of ultrasonic low-attenuation material, such as eptfe film.
同时，将超声发射单元4和超声接收单元5安装在透音区11出，一个透音区11与一个超声发射单元4或一个超声接收单元5对应，以便超声发射单元4能够通过透音区11直接将超声信号传出壳体1，及超声接收单元5能够收到直达超声信号。At the same time, the ultrasonic transmitting unit 4 and the ultrasonic receiving unit 5 are installed in the sound-transmitting area 11, and one sound-transmitting area 11 corresponds to one ultrasonic transmitting unit 4 or one ultrasonic receiving unit 5, so that the ultrasonic transmitting unit 4 can directly transmit the ultrasonic signal out of the shell 1 through the sound-transmitting area 11, and the ultrasonic receiving unit 5 can receive the direct ultrasonic signal.
为了避免超声防丢追踪器的超声接收单元5被自身的超声发射单元4发出的超声信号影响，将超声接收单元5安装至对应透音区11后，在壳体1内部安装上屏蔽腔14将部分超声接收单元5包覆，这里，屏蔽腔14为金属材质，从而屏蔽超声防丢追踪器的超声发射单元4发出的超声信号，而需要测距用的超声接收单元5不设置屏蔽腔14进行阻隔，保证其能接收到超声发射单元5的信号。In order to prevent the ultrasonic receiving unit 5 of the ultrasonic anti-lost tracker from being affected by the ultrasonic signal emitted by its own ultrasonic transmitting unit 4, after the ultrasonic receiving unit 5 is installed in the corresponding sound-transmitting area 11, a shielding cavity 14 is installed inside the shell 1 to partially cover the ultrasonic receiving unit 5. Here, the shielding cavity 14 is made of metal, thereby shielding the ultrasonic signal emitted by the ultrasonic transmitting unit 4 of the ultrasonic anti-lost tracker. The ultrasonic receiving unit 5 that needs to be used for ranging is not provided with a shielding cavity 14 for isolation, thereby ensuring that it can receive the signal of the ultrasonic transmitting unit 5.
另外，超声发射单元4还能在处理器2的驱动下发出可听声，产生蜂鸣提示效果。In addition, the ultrasonic transmitting unit 4 can also emit an audible sound under the drive of the processor 2 to produce a buzzing prompt effect.
为了方便拆卸替换电池，壳体1包括上壳体12和下壳体13，上壳体12底部开有供电池3嵌入的电池仓121，所述下壳体13可拆卸安装于上壳体12底部，可拆卸结构可为：在电池仓121周围开设卡槽(图中未示出)，在下壳体13上 设计预期配合的卡扣(图中未示出)。In order to facilitate the removal and replacement of the battery, the shell 1 includes an upper shell 12 and a lower shell 13. A battery compartment 121 for embedding the battery 3 is opened at the bottom of the upper shell 12, and the lower shell 13 can be detachably installed at the bottom of the upper shell 12. The detachable structure can be: a card slot is opened around the battery compartment 121 (not shown in the figure), and an expected matching buckle is designed on the lower shell 13 (not shown in the figure).
实施例3：一种超声防丢追踪***，参照附图1～4，包括配对使用的智能设备01和防丢追踪器02，智能设备01具有至少一个超声发射单元4和至少两个超声接收单元5，防丢追踪器02包括集成于壳体1中的的一个超声发射单元4、一个超声接收单元5、处理器2、蓝牙模块6和电池3，超声发射单元4、超声接收单元5、处理器2和蓝牙模块6分别通过线路与处理器2连接，这里，超声发射单元4和超声接收单元5与处理器的连接之间还具有数模转换器等元器件，实现处理器驱动超声发射单元4发出超声信号和超接收单元5接收超声信号的功能，实现的电路为现有技术，不做赘述。使用时，处理器2驱动蓝牙模块6持续发出蓝牙广播信号，便于用户携带的智能设备(手机)扫描找到对象。而电池3用于为超声防丢追踪器中所有的用电元器件供电。Embodiment 3: An ultrasonic anti-lost tracking system, referring to Figures 1 to 4, includes a paired smart device 01 and an anti-lost tracker 02, the smart device 01 has at least one ultrasonic transmitting unit 4 and at least two ultrasonic receiving units 5, the anti-lost tracker 02 includes an ultrasonic transmitting unit 4, an ultrasonic receiving unit 5, a processor 2, a Bluetooth module 6 and a battery 3 integrated in the housing 1, the ultrasonic transmitting unit 4, the ultrasonic receiving unit 5, the processor 2 and the Bluetooth module 6 are respectively connected to the processor 2 through lines, here, there are also components such as digital-to-analog converters between the connection between the ultrasonic transmitting unit 4 and the ultrasonic receiving unit 5 and the processor, to realize the function of the processor driving the ultrasonic transmitting unit 4 to emit ultrasonic signals and the ultrasonic receiving unit 5 to receive ultrasonic signals, the circuit implemented is the prior art and will not be described in detail.

特别地，为了弥补超声在强遮挡环境下的不足，蓝牙模块6也可以具有定位功能，在超声失准时启动，进行模糊/精确定位，进一步提高用户体验。In particular, in order to make up for the shortcomings of ultrasound in a strong occlusion environment, the Bluetooth module 6 may also have a positioning function, which is activated when the ultrasound is inaccurate to perform fuzzy/precise positioning to further improve the user experience.
上述方案利用超声发射单元和超声接收单元配合手机自带的麦克风和扬声器即能实现测距测角，给出距离和指向信息，实现近距离精确查找，超声发射单元和超声接收单元(麦克风和扬声器)价格低廉，成本低，且用户无需携带手机移动即能完成定位，十分便捷；同时，将超声发射单元和超声接收单元内置于壳体中，既能避免其受到损伤，又能提高防丢追踪器一体化程度，便于使用、设计美观。The above scheme utilizes the ultrasonic transmitting unit and the ultrasonic receiving unit in conjunction with the microphone and the speaker of the mobile phone to realize distance and angle measurement, provide distance and direction information, and realize close-range precise search. The ultrasonic transmitting unit and the ultrasonic receiving unit (microphone and speaker) are inexpensive and low-cost, and users can complete positioning without carrying the mobile phone, which is very convenient.
