Description

Method and device for voice communication based on automobile data recorder

Technical Field

The invention relates to the technical field of wireless communication, in particular to a method and a device for voice communication based on a vehicle event data recorder.

Background

For most of the current automobiles, the automobile data recorder is carried along with the automobile to record real-time video during driving, and the existing automobile data recorder only has the function of recording the real-time video during driving. For driving users who have more outdoor activities such as donkey friends and car friends and often drive to go out, the voice communication needs to be carried out with other driving users.

The traditional interphone uses the radio broadcasting technology, the calling interphone generally broadcasts the voice information to the wireless talkback channel, and the opposite interphone receives the voice information through the wireless talkback channel and plays the voice information. However, the transmission power of the conventional intercom is usually small, which results in a short broadcasting distance of the wireless signal and cannot support long-distance voice communication. Since the frequency bands of the wireless intercom channels used by the conventional intercom are usually 150Mhz frequency band and 400Mhz frequency band, the mobile internet with higher operating frequency cannot be supported, for example, the 3G mobile communication network serving as the access network in the mobile internet usually operates in the 2Ghz frequency band, so that the conventional intercom cannot perform voice communication at a longer distance through the mobile internet because the conventional intercom does not support the frequency band of the mobile internet.

Currently, a user can use a mobile phone to perform voice communication with a user using another mobile phone through a mobile communication network. Although the mobile phone supports long-distance voice communication, the mobile phone is out of the coverage area of the mobile communication network, and voice communication cannot be carried out. Moreover, the mobile phone usually does not support the frequency band of the radio intercom channel, and cannot perform voice communication through the radio intercom channel.

Meanwhile, for users with more outdoor activities such as exploration personnel, rescue personnel, donkey friends and car friends, the users usually need to carry a mobile phone and an interphone at the same time, so that the mobile phone is used for voice communication in an area covered by a mobile communication network, and the interphone is used for voice communication in an area not covered by the mobile communication network; that is to say, the user is required to carry two voice communication devices, namely the mobile phone and the interphone, and the user is required to judge whether the area is covered by the mobile communication network by himself, and the user manually selects the mobile phone or the interphone to carry out communication, so that the whole process is complicated in operation and inconvenient to use, and user experience is poor.

After logging in the mobile internet, the calling automobile data recorder 1 generates a first voice communication request based on the identification code and the network address of the automobile data recorder and first voice information input by a calling user, and sends the first voice communication request to the voice talkback server 2 through the mobile internet. The network address may specifically be an IP address; the first voice communication request may specifically include a plurality of data frames based on a TCP/IP (Transmission Control Protocol/Internet Protocol) Protocol.

When the calling automobile data recorder 1 detects that the calling automobile data recorder is connected to the network, a first voice communication request generated according to the first voice information and the identification code of the calling automobile data recorder is sent to the voice talkback server 2 through the network.

Optionally, the method further includes step S2140 (not shown), step S2150 (not shown), and step S2160 (not shown); step S2140: when the fact that the calling automobile data recorder 1 cannot be connected to the network is detected, pre-stored frequency point information of a wireless talkback channel corresponding to a group to which the calling automobile data recorder 1 belongs is extracted; step S2150: broadcasting the first voice information through a wireless talkback channel to which the frequency point information belongs; step S2160: and receiving second voice information from the opposite-end automobile data recorder 3, which is returned by the opposite-end automobile data recorder 3 through the wireless talkback channel to which the frequency point information belongs.

And when the fact that the calling automobile data recorder 1 cannot be connected to the network is detected, pre-stored frequency point information of a wireless talkback channel corresponding to a group to which the calling automobile data recorder 1 belongs is extracted, and the first voice information is broadcasted through the wireless talkback channel to which the frequency point information belongs. Wherein the operating frequency of the radio intercom channel can be in the range of 100-500 Mhz.

In a preferred embodiment, the voice talkback server 3 determines frequency point information of a wireless talkback channel corresponding to a group to which the calling automobile data recorder 1 belongs according to the group to which the calling automobile data recorder belongs; sending the frequency point information of the wireless talkback channel to a calling automobile data recorder 1 and an opposite-end automobile data recorder 3 in the group; when the calling automobile data recorder 1 is connected to a network, the calling automobile data recorder receives frequency point information of a wireless talkback channel corresponding to a group to which the calling automobile data recorder belongs, wherein the frequency point information is sent by the voice talkback server 2; and pre-storing the received frequency point information.
