Problems solved by technology

Theoretically speaking, a Bluetooth device can switch between the active mode and the passive mode, but when the existing Bluetooth device needs to switch from the passive mode to the active mode, it needs the user's artificial input and output operations. Under the condition of the input and output operation of the Bluetooth device, the Bluetooth device basically only works as a slave device in a passive mode, thus weakening the function of the Bluetooth device
Moreover, for the Bluetooth device applied on the HUD, since the driver needs to focus on various driving operations, if the driver artificially operates the Bluetooth device on the HUD, it will inevitably increase the operational complexity and distract the driver's attention. Reduce driving safety to obtain data information from external devices

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0027] see figure 1 , is a structural schematic diagram of an embodiment of the Bluetooth communication connection between the head-up display provided by the present invention and an external device.

[0028] Among them, the user may need to transmit the data information of the external device 102 with the Bluetooth function to the head-up display (HUD) 101 with the Bluetooth function for display during the process of driving the aircraft or the vehicle, or may need to display the data information of the aircraft or vehicle obtained by the HUD101. The vehicle driving information is transmitted to the external device 102, through which the external device 102 further communicates with an Internet connection device. In this embodiment, the external devices 102 include but are ...

Abstract

The invention discloses a Bluetooth communication connection method of a head-up display. The method comprises the steps of: after the head-up display is powered on, judging whether a Bluetooth communication connection request sent by an external device is received; when the head-up display receives the Bluetooth communication connection request sent by the external device, controlling the head-up display to work under a passive mode and carry out point-to-point Bluetooth communication with the external device; and when the head-up display does not receive the Bluetooth communication connection request sent by the external device, controlling the head-up display to work under an active mode and periodically searching for external devices for Bluetooth matching, and when the Bluetooth matching is successful, carrying out point-to-point Bluetooth communication with one external device or carrying out one-point-multi-address Bluetooth communication with a plurality of external devices. By adopting the Bluetooth communication connection method of the head-up display, automatic switching between the passive mode and the active mode of a HUD Bluetooth device is realized.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a Bluetooth communication connection method for a head-up display. Background technique [0002] The predecessor of the Head Up Display (HUD) is an optical sight used on fighter jets. This sight uses the principle of optical reflection to project a ring-shaped aiming circle light net on the front display screen of the cockpit of the device. Since the projected image is set at an infinite distance to the naked eye, when the pilot is aiming at the target, it will not hinder the operation of the eyes and maintain a clear display. Because the HUD display can reduce the frequency that the driver needs to look down at the instrument, avoid interruption of attention, its convenience and can improve driving safety, civil aircraft and motor vehicles have also followed up the installation. [0003] Among them, for motor vehicles, when the motor vehicle is driving at high ...
