Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth watches, and in particular to a high-precision positioning Bluetooth watch based on dual-frequency GPS8. Background Art

[0002] A Bluetooth watch is a watch with Bluetooth function. It is a kind of multifunctional smart communication watch. Through the Bluetooth function of the watch, it can be paired with a Bluetooth mobile phone for use. Some Bluetooth watches have call and dial functions, so users do not need to keep their mobile phones with them at all times, and can also know whether there are calls or messages, and will not miss important calls.

[0003] However, most of the existing Bluetooth watches in the prior art use GPS single-frequency positioning. Therefore, in crowded roads or tunnels and mountain roads with poor signals, it is very easy for the positioning to update slowly, which in turn affects the user's judgment of their own location and causes the user to miss the intersection.

[0004] Therefore, a high-precision positioning Bluetooth watch based on dual-frequency GPS8 is provided to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to: address the problem.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0007] A high-precision positioning Bluetooth watch based on dual-frequency GPS8, comprising a shell, a retaining frame fixedly installed inside the shell, a lithium battery movably connected inside the retaining frame, a control mainboard provided on one side of the lithium battery and connected to the retaining frame, a wireless charging module provided on the bottom of the control mainboard, an electric control button provided in the middle of the upper surface of the control mainboard, a GPS module welded on one side of the control mainboard, the GPS module is a five-star ten-frequency L1+L5 positioning GNSS module, which is integrated into an ARM Cortex-M4 FPU and MPU with a main frequency of up to 530MHz, and the module supports GPS, BDS, GLONASS, GALILEO and QZSS multi-satellite systems, a control chip is welded on one side of the GPS module where the control mainboard is located, and a Bluetooth transceiver is welded on the other side of the GPS module where the control mainboard is located.

[0008] As a preferred technical solution of the present application, a back plate is movably mounted on one side of the shell by bolts, watch straps are movably connected to both sides of the shell, and a control button is movably connected to the shell.

[0009] As a preferred technical solution of the present application, a contact is fixedly connected to the bottom end of the control button and contacts the electric control button through the contact, and the wireless charging module is connected to the charging end of the lithium battery.

[0010] As a preferred technical solution of the present application, a display screen is movably connected to one side of the shell, a power supply line of the display screen is connected to the control mainboard, and a rubber ring is movably connected to one side of the display screen.

[0011] As a preferred technical solution of the present application, a tempered glass layer is provided on one side of the rubber ring and is clamped to the shell, a clamping groove is opened on one side of the back panel, and a positioning frame is movably clamped through the clamping groove, and the positioning frame is fixedly connected to the retaining frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the scheme of this application:

[0014] Through the Bluetooth transceiver, control chip and GPS module, the watch can simultaneously transmit information with multiple satellites when performing positioning operations, and receive the L1+L5 bands of each satellite, thereby completing the operation of multi-signal information overlapping positioning. At the same time, in the dual-frequency positioning technology, the code rate of L1 and L5 signals is higher than that of single frequency, so that each code occupies a shorter time, thereby improving the positioning accuracy. The refractive index of L1 and L5 signals through the same medium is different, which can effectively reduce the positioning error caused by the atmosphere. This solves the problem that most of the existing technologies use GPS single-frequency positioning. Therefore, in crowded sections or tunnels and mountain roads with poor signals, it is very easy to have slow positioning updates, which in turn affects the user's judgment of their own position and leads to the problem of missing the intersection.
