Problems solved by technology

[0022] The existence of these phenomena has led to the unsmooth and incomplete broadcast of the voice information of the GPS navigation system. The voice broadcast will be cut off, affecting the user experience, and may cause the user to be unable to make corresponding vehicle steering in time due to incomplete voice information. Actions such as control

Embodiment Construction

[0048] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0049] After the broadcast collection buffer that can buffer and store the voice broadcast instruction is set in the voice broadcast device, the problem that the original voice broadcast may be truncated has been solved, but this has brought new problems. For example, we can set the broadcast collection buffer as a queue, and the newly generated voice broadcast instructions enter the queue from the end of the queue in the order in which they are generated; the voice broadcast device reads the voice broadcast instructions from the head of the queue; the read voice broadcast instructions Instructions are dequeued and deleted. Although this technical solution solves the problem that the voice broadcast may be truncated, there may be a situation that the generated voice broadcast instruction cannot be broadcast in time. Since there are too many v...

Abstract

The invention discloses a voice broadcasting device, a navigation system that uses the voice broadcasting device and a method that is adopted by the navigation system; wherein, the voice broadcasting device comprises a voice instruction broadcasting module and a broadcast collection buffer which is used for receiving and storing the voice broadcast instructions that contain broadcast content and are generated by the navigation system, the voice instruction broadcasting module obtains the voice broadcast instruction from the broadcast collection buffer, transforms the voice broadcast instruction to sound data and sends the sound data to an sound output device of the navigation system. As the invention leads the broadcast collection buffer that is used for receiving and storing the generated voice broadcast instructions to be arranged in the voice broadcasting device of the navigation system, when the voice instruction broadcasting module broadcasts a voice broadcast instruction, a newly generated voice broadcast instruction is sent into the broadcast collection buffer for being buffered and stored, and after the broadcast of the current voice broadcast instruction is finished, the broadcast of a next voice broadcast instruction is implemented, thus avoiding the situation that the voice broadcasting is cut off.

Description

technical field [0001] The invention relates to the field of GPS navigation, more specifically, to a voice broadcasting device used in a GPS navigation device, a navigation system using the device and a voice broadcasting method adopted by the navigation system. Background technique [0002] At present, the GPS navigation system is one of the important application directions of the GPS positioning system. The GPS antenna of the GPS navigation system receives the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the vehicle navigation terminal, the position coordinates determined by the GPS satellite signal match this, Determine the exact position of the navigation object in the electronic map, and guide the route near the position. [0003] figure 1 The structural composition of existing car navigation system is shown: described car navigation system comprises: loudspeaker 1, chuck device 2, inp...
