BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0027] Figure 1 It is a structural diagram of a Beisan vehicle-mounted data transmission terminal based on Bluetooth communication provided in one embodiment of the present application. DETAILED DESCRIPTION

[0028] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0029] Figure 1 This is a schematic diagram of the structure of the Beisan vehicle-mounted data transmission terminal based on Bluetooth communication provided by an embodiment of the present application. Figure 1 The present application provides a BeiDou vehicle-mounted data transmission terminal based on Bluetooth communication, including: a BeiDou module 10, a Bluetooth module 20, a microprocessor 30, an acceleration sensor 40, and a power module 50.

[0030] The Beidou module 10 , the Bluetooth module 20 , the acceleration sensor 40 , and the power module 50 are electrically connected to the microprocessor 30 , respectively.

[0031] The Beidou module 10 is used to communicate with Beidou satellites and obtain vehicle positioning information.

[0032] The Beidou module 10 includes a Beidou antenna 11 and a Beidou module 12. The Beidou antenna 11 is electrically connected to the Beidou module 12. The Beidou antenna 11 is used to receive Beidou satellite positioning data and send Beidou satellite positioning request information. The Beidou module 12 is used to demodulate the Beidou satellite positioning data and modulate the Beidou satellite positioning request information, and output vehicle positioning information.

[0033] In one embodiment, the Beidou antenna 11 is a Beidou transceiver antenna, which can be used to transmit and receive Beidou satellite radio frequency signals. The Beidou module 12 integrates LNA, RDSS radio frequency transceiver chip, power amplifier, Beidou-3 dedicated baseband circuit, etc., which can realize Beidou communication positioning function, and has the characteristics of simple application, high integration, small size and low power consumption.

[0034] The Bluetooth module 20 is used to perform Bluetooth communication with the peripheral terminal, and the peripheral terminal controls the vehicle-mounted data transmission terminal through the Bluetooth module 20. The Bluetooth module 20 includes a Bluetooth antenna 21 and a Bluetooth matching module 22; the Bluetooth antenna 21 is electrically connected to the Bluetooth matching module 22, and the Bluetooth matching module 22 is used to match the vehicle-mounted data transmission terminal with the peripheral terminal during data transmission.

[0035] In one embodiment, the Bluetooth matching module 22 integrates peripheral hardware circuits and chips into a PCBA board, connects to the microprocessor 30 through the IO serial port, realizes data information transmission, Bluetooth communication and networking functions, achieves short-range wireless communication purposes, and can also realize the built-in program Bluetooth function required by electronic products.

[0036] The acceleration sensor 40 is used to obtain the spatial position data of the vehicle. The acceleration sensor 40 is a 3-axis digital accelerometer sensor; the 3-axis digital accelerometer sensor is used to obtain the pitch angle, left and right yaw angle, and vertical rotation angle according to the spatial position data, and the microprocessor 30 is also used to output an alarm prompt when any one of the pitch angle, left and right yaw angle, and vertical rotation angle is greater than a preset angle threshold.

[0037] A triaxial accelerometer is a sensor used to measure spatial acceleration, that is, to measure the speed of an object's velocity change in space, and is used to measure the acceleration of an object in three different directions (usually the x, y, and z axes). It usually uses a small mechanical structure that contains a oscillator or mass point, and uses a Piezoresistive or capacitive sensor to measure the position change of the oscillator or mass point.

[0038] According to the implementation principle of the acceleration sensor, the main types of acceleration sensors currently include: piezoresistive, piezoelectric, and capacitive. They convert the acceleration of the object to be measured into a change in the resistance / voltage / capacitance of the sensor unit, and then convert the change value of the sensor unit into a voltage value through a conversion circuit, and then perform corresponding signal amplification and filtering processing to process the analog quantity into a suitable stable output signal. At this time, the output signal is a voltage value, and finally converted into a digital signal through an ADC converter (analog-to-digital converter). The acceleration sensor 40 of the present application can be a capacitive acceleration sensor.

[0039] Furthermore, when a vehicle enters an area or environment where satellite signal reception is poor, the navigation function may be lost due to loss of signal. The 3-axis acceleration sensor of the present application can be used with a gyroscope or an electronic compass to create a dead reckoning system, realizing complementary positioning applications for the Beidou system.

[0040] In one embodiment of the present application, the preset angle threshold is set to 45 degrees, and an early warning is immediately sent when the vehicle tilt angle is greater than 45°.

The power module 50 includes a power management module 51 and a battery pack 52; the power management module 51 and the battery pack 52 are electrically connected to monitor the use status and fault conditions of the battery pack 52. The power module 50 also includes a charging circuit; the charging circuit is electrically connected to the battery pack 52 and the vehicle-mounted power supply, and is used to reduce the high voltage output of the vehicle-mounted power supply to low voltage to charge the battery pack 52.

[0042] In one embodiment of the present application, the battery pack 52 is a lithium thionyl chloride battery pack. The nominal capacity of the ER34615 lithium thionyl chloride battery is 19Ah, the operating temperature is between -55°C and 85°C, and the service life is more than 10 years. The use of a lithium thionyl chloride battery pack can reduce external power supply and improve the practicality and convenience of the product.

[0043] The microprocessor 30 is used to output an alarm prompt when the spatial position does not meet the preset conditions, and to control the power module 50 to output a sleep current when the vehicle-mounted data transmission terminal is in a sleep state. In one embodiment of the present application, the microprocessor 30 is an MCU (Microcontroller Unit). The microprocessor 30 can also be used to perform the following operations: 1. Process the information received by the Bluetooth module 20 and compress it into packets, and encode and send it in packets according to the Beisan communication protocol; 2. Process the received data of the Beidou module 10, and transmit it to the display and control terminal according to the rule package analysis; 3. Control power consumption, sleep when not in use, and use trigger wake-up to enter the working mode; 4. Monitor the driving status of the vehicle, send an early warning when the vehicle tilt angle is greater than 45°, and send an alarm and report the position when the vehicle tilt angle is continuously greater than 45° within a preset time (for example, 5 minutes).

[0044] Optionally, the vehicle-mounted data transmission terminal further includes a display screen (not shown in the figure), which is connected to the microprocessor 30 and is used to display vehicle positioning information and alarm prompts.

[0045] Optionally, the display screen is a touch screen; the touch screen is used to output wake-up information to the microprocessor 30 when a touch operation is sensed, so that the microprocessor 30 controls the power module 50 to output a working current.

[0046] Optionally, the vehicle-mounted data transmission terminal further includes a memory (not shown in the figure); the memory is connected to the microprocessor 30 and is used to store offline maps;

[0047] The microprocessor 30 is also used to perform positioning according to the offline map when no Beidou satellite positioning data is received.

[0048] The present application also provides a vehicle, comprising the above-mentioned Beisan vehicle-mounted data transmission terminal based on Bluetooth communication.

[0049] The principle of the technical solution of the present invention is as follows: (1) The vehicle-mounted data transmission terminal uses a Bluetooth module to connect to the smart terminal and uses the APP for data interaction, which reduces the trouble of connecting cables and improves convenience. At the same time, the APP supports text, voice, and picture transmission. (2) It uses an ER34615 lithium thionyl chloride battery for power supply. The nominal capacity of the ER34615 lithium thionyl chloride battery is 19Ah, the operating temperature is between -55°C and 85°C, and the service life is more than 10 years, which reduces external power supply and improves the practicality and convenience of the product. (3) The vehicle-mounted data transmission terminal is also equipped with a 3-axis digital accelerometer sensor. When the car tilts 45°, an alarm prompt is issued to the vehicle-side platform. When the alarm is issued continuously, the location is reported to the traffic police platform, thereby improving the intelligence of the vehicle-mounted data transmission terminal.
