Problems solved by technology

With the continuous development of in-vehicle audio-visual equipment and the continuous improvement of in-vehicle navigation systems, the combination of "Push-to-Talk" and in-vehicle main control system realizes functions such as hands-free answering of mobile phones in the vehicle; on the other hand, the operation control of the current in-vehicle navigation system, It is still in the stage of full manual operation, but it is quite dangerous to search and set the destination during driving. Therefore, you must first find a safe parking spot and then perform navigation operations. It is quite inconvenient to use. Therefore, how to provide a method of simplifying the destination setting procedure that can combine "push to talk" with the navigation system has become a subject worthy of discussion

Embodiment 1

[0014] Such as figure 1 As shown, a method for realizing Bluetooth push-to-talk navigation destination setting, wherein it needs to start a bluetooth module equipped with a push-to-talk function, the bluetooth module is mainly composed of a main controller MCU and a bluetooth sending module, the main controller MCU It adopts CSR's mid-to-high-end Bluetooth receiving and sending chip BC5.

[0015] A method for realizing bluetooth push-to-talk navigation destination setting is characterized in that it first starts the push-to-talk device connected with the bluetooth module, after the bluetooth module is paired with the user's mobile phone, the user's mobile phone dials the background system phone, and the After the seat operator in the background system answers the call and understands the user's needs, he operates the background system and encodes it through the DTMF / FSK codec, and returns the voice signal data corresponding to the map coordinate data to the user's mobile phone...

Embodiment 2

[0019] Such as figure 2 As shown, the difference between the present embodiment and the foregoing embodiments is that after the mobile phone receives the voice signal data, it is first sent to the main controller MCU 3, DTMF / FSK codec and The Bluetooth base of the wireless transmission module is decoded by the Bluetooth base and then sends the information to the main controller MCU in the vehicle for storage. The wireless transmission module is a 2.4G wireless transmitter.

Abstract

The invention discloses a method for realizing setting of a navigating destination through bluetooth push-to-talk. The method is characterized by comprising the following steps of: firstly, starting a push-to-talk device which is connected with a bluetooth module; after matching the bluetooth module with a user mobile phone, dialing a background system phone number by the user mobile phone; after answering the call and understanding a user requirement by a telephone operator of the background system, operating the background system and encoding through DTMF/FSK (Dual Tone Multiple Frequency/Frequency Shift Keying) coder and decoder; returning voice signal data corresponding to map coordinate data to the user mobile phone through a mobile phone network; after receiving the voice signal data by the user mobile phone, sending the voice signal data to the DTMF/FSK decoder in the manner of mobile phone bluetooth; after decoding by the DTMF/FSK decoder, storing in a vehicle master controller MCU (Micro Controller Unit); and lastly, extracting map coordinate information from a memory by a navigating system in a vehicle-mounted terminal and starting a navigating service. The method provided by the invention has the advantages of low cost, high decoding speed and excellent popularizing value.

Description

technical field [0001] The invention relates to the technical field of vehicle navigation, and more specifically relates to a method for realizing the setting of a Bluetooth push-to-talk navigation destination. Background technique [0002] The so-called "Push-To-Talk" (English abbreviation PTT, that is, Push-To-Talk) is actually a mobile phone integrated with a walkie-talkie function. Users can press the intercom button on the mobile phone to communicate directly with groups or individuals anywhere. Make a call. With the continuous development of in-vehicle audio-visual equipment and the continuous improvement of in-vehicle navigation systems, the combination of "Push-to-Talk" and in-vehicle main control system realizes functions such as hands-free answering of mobile phones in the vehicle; on the other hand, the operation control of the current in-vehicle navigation system, It is still in the stage of full manual operation, but it is quite dangerous to search and set the ...
