[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0027] Currently, positioning modules used in locators are generally satellite positioning, such as GPS or BeiDou. Satellite positioning offers advantages such as high accuracy and wide coverage. However, satellite positioning consumes a significant amount of power. When a locator uses only satellite positioning, the limited battery capacity significantly shortens the device's standby time while the satellite module is continuously operating. Bluetooth and WiFi positioning are also available, but these methods are generally suitable for indoor areas with weak GPS signals and require a fixed signal source in the positioning environment, thus limiting the positioning scenarios. Using Bluetooth or WiFi positioning alone may result in no positioning data. Therefore, to address these issues, this application proposes a technical solution to ensure the positioning efficiency of the locator while reducing power consumption.

[0028] Please see Figures 1-3 This utility model provides a technical solution:

[0029] like Figure 1As shown, this utility model provides a dual-mode locator, including a main control module 1, a first positioning module 3, a second positioning module 4, a conversion module 2, an antenna module, and a power module 5. The first positioning module 3 and the second positioning module 4 are connected to the main control module 1 through the conversion module 2, and the power module 5 and the antenna module are connected to the main control module 1.

[0030] The first positioning module 3 is a Bluetooth module that supports the Tag protocol, and the second positioning module 4 is a satellite positioning module.

[0031] In the embodiments of this application, the locator includes two positioning modules: a first positioning module 3, which is a Bluetooth module supporting the Tag protocol, and a second positioning module 4, which is a satellite positioning module. The first positioning module 3 supports the Tag protocol, a protocol for Bluetooth Low Energy communication that allows devices supporting this protocol to be discovered and identified as "tags." The first positioning module 3 can access the Find My network based on the Tag protocol to achieve positioning functionality. In the Find My network, a large number of devices supporting the relevant Tag protocol can form a positioning system. When the dual-mode locator of this application enters the network's coverage area, the first positioning module 3 can determine its location by communicating with surrounding devices based on the Tag protocol. The second positioning module 4 can be a GPS positioning module or a BeiDou positioning module. When using the second positioning module 4 for positioning, positioning data can be obtained through the satellite positioning network. The first positioning module 3 has low power consumption, which can effectively reduce the power consumption of the positioning device and extend its standby time. The second positioning module 4 has a wide positioning range and can effectively make up for the time period when the first positioning module 3 cannot be positioned. The first positioning module 3 and the second positioning module 4 are connected to the main control module 1 through the conversion module 2. The main control module 1 can control one of them to perform positioning.

[0032] In some specific embodiments, the first positioning module 3 may be an ASR5601 chip, and the second positioning module 4 may be an AT6558 chip.

[0033] In order to transmit the positioning data to the management backend, the dual-mode locator of this application also includes a cellular communication module 6, which is connected to the main control module 1.

[0034] Specifically, the cellular communication module 6 may be a 4G communication module. In this application, the cellular communication module 6 is used to transmit the positioning data obtained by the second positioning module 4 to the management backend.

[0035] The antenna module includes a Bluetooth antenna, a satellite antenna, and a cellular communication antenna 9.

[0036] Furthermore, to save internal space in the locator, the Bluetooth antenna and satellite antenna are combined into one antenna 8; to ensure the quality of the antenna signal reception, the cellular communication antenna 9 includes a main antenna and a diversity antenna.

[0037] In the embodiments of this application, the dual-mode antenna 8 is connected to the RF pins of the first positioning module 3 and the second positioning module 4 via RF switches. The main control module 1 is connected to the control terminal of the RF switch to select the positioning module to transmit the antenna signal, ensuring that the two positioning modules can effectively use the antenna for signal transmission and reception at different times. When the first positioning module 3 is working, the RF switch connects the antenna to the RF pin of the first positioning module 3, enabling it to transmit Bluetooth broadcast signals; when the second positioning module 4 is working, the RF switch switches the connection, enabling the second positioning module 4 to receive satellite positioning signals.

[0038] The dual-purpose antenna 8 and cellular communication antenna 9 are FPC antennas. FPC antennas are thin, light and flexible, and can be attached to irregular surfaces or narrow spaces inside the locator, effectively saving space and helping to achieve miniaturization and thinning of the locator.

[0039] Furthermore, the conversion module 2 is an analog switch chip, and the NO1 pin and NC1 pin of the analog switch chip are respectively connected to the RX_BT pin and RX_GPS pin of the first positioning module 3 and the second positioning module 4;

[0040] The SEL pin of the analog switch chip is connected to the GPIO pin of the main control module 1 for controlling the switching of connection channels; the COM2 pin of the analog switch chip is connected to the UART RX pin of the main control module 1 for data transmission.

[0041] like Figure 2 As shown in the embodiments of this application, the conversion module 2 can be an SGM3005 analog switch, and the main control module 1 is connected to the control pin of the analog switch chip. By outputting high and low level signals, the main control module 1 can control the conduction switching of the analog switch, thereby realizing the switching of the working state of the first positioning module 3 and the second positioning module 4.

[0042] Furthermore, the first positioning module 3 is connected to the power module 5 via a power switch, and the power switch is connected to the GPIO pin of the main control module 1 to control the opening and closing of the power switch.

[0043] Specifically, the power switch is a PMOS transistor. When the GPIO pin of the main control module outputs a high level, the PMOS transistor is turned off, cutting off the power supply to the first positioning module 3. When the GPIO pin of the main control module outputs a low level, the PMOS transistor is turned on, supplying power to the first positioning module 3.

[0044] To ensure the operation of the first positioning module 3, the operating voltage of the first positioning module 3 is 1.8V-5.5V.

[0045] like Figure 3 As shown in the embodiment of this application, the positive terminal of the power module 5 is connected to the source of the PMOS transistor, and the drain of the PMOS transistor is connected to the power input pin of the first positioning module 3. Since the operating voltage of the first positioning module 3 is lower than that of the main control module 1, under this connection method, when the overall power of the locator is low, as long as the power module 5 has enough power to meet the operating voltage requirements of the first positioning module 3, it can continuously supply power to it and connect to the Find My network for positioning.

[0046] Furthermore, it also includes a sensor module 7 and an alarm module 10 connected to the main control module 1.

[0047] The sensor module 7 includes an accelerometer or a gyroscope. For example, the accelerometer's acceleration signal can be used to automatically identify whether the locator is in motion or stationary. When the locator moves, the main control module 1 first controls the first positioning module 3 to broadcast at a preset frequency. When a device is connected to the Find My network through the first positioning module 3, the Find My network is used to record the positioning data. Furthermore, the positioning scenario of the first positioning module 3 is not limited to indoor locations. It can be used for positioning outdoors as long as it can access the Find My network, greatly expanding the application scenarios of Bluetooth positioning.

[0048] If positioning data is not obtained through the first positioning module 3, the main control module 1 controls the switching of the second positioning module 4 to obtain positioning data using the satellite network.

[0049] The alarm module 10 includes an indicator light and a buzzer. The indicator light can be used to indicate the device status and provide guidance for finding items, and the buzzer can be used to emit a prompt sound.
