Embodiment 1

[0024] Please refer to figure 1 , the present embodiment provides a vehicle-mounted T-BOX system, including a vehicle-mounted microphone, a vehicle-mounted T-BOX connected to the vehicle-mounted microphone, the vehicle-mounted T-BOX includes an MCU control module, a communication module connected to the MCU control module, a backup power supply module and Audio module, the audio module is connected to the communication module and the backup power module; the communication module is integrated with a DSP audio circuit, when the vehicle suffers serious damage or the body battery fails, the on-board T-BOX will automatically switch to the backup power module for power supply, Start the audio channel of the internal DSP audio circuit to realize emergency call rescue. When the external audio channel is normal, the MCU control module will control the shutdown of the backup power supply module and audio module to reduce power consumption, save power, and prolong the service life of the...

Embodiment 2

[0031] The present embodiment provides a call control method of a vehicle-mounted T-BOX system, comprising the following steps: S1, the MCU control module monitors the call request signal of the communication module in real time; S2, if the communication module has a call request, the MCU control module controls The communication module opens the audio channel of the internal DSP audio circuit; if the communication module does not have a call request, then return to step S1; S3, the MCU control module monitors the interrupt request signal of the external audio channel in real time, and selects the audio channel for the call according to the monitoring result.

[0032] In step S3, the following processes are included: S31. If an interrupt request signal is detected, the MCU control module controls to close the backup power supply module and the audio module, and the T-BOX conversation is completed by the external audio path;

[0033] S32, if no interrupt request signal is detect...

Abstract

The present invention relates to the field of vehicle-mounted T-box technology, and specifically discloses a vehicle-mounted T-BOX system and a call control method, including a vehicle-mounted microphone, and a vehicle-mounted T-BOX connected to the vehicle-mounted microphone. The vehicle-mounted T-BOX includes an MCU control module, A communication module connected to the MCU control module, a backup power module and an audio module, the audio module is connected to the communication module and the backup power module; the communication module is integrated with a DSP audio circuit, and the present invention can be used when the vehicle suffers serious damage or When the body battery fails, the on-board T-BOX will automatically switch to the backup power supply module for power supply, and start the audio channel of the internal DSP audio circuit to realize emergency call rescue. When the external audio channel is normal, the MCU control module will control the shutdown of the backup power supply Module and audio module, reduce power consumption, achieve the purpose of saving power and prolonging the use time of backup batteries.

Description

technical field [0001] The invention relates to the field of vehicle T-box technology, in particular to a vehicle T-BOX system and a call control method. Background technique [0002] The collision emergency rescue call in the current vehicle T-BOX system is to transmit the emergency call through the antenna through the communication module in the vehicle T-BOX, after the transfer of the base station, the phone number to be dialed is searched, and the external audio channel is connected To play the sound during the call, so as to realize the wireless call. [0003] However, when the vehicle suffers serious damage, the body battery fails, or the external audio channel connected to the vehicle T-BOX fails, the vehicle T-BOX cannot play the sound of the call through the external audio channel. At this time, the vehicle T-BOX BOX's collision emergency rescue phone cannot establish a call, and cannot achieve the purpose of emergency rescue. Contents of the invention [0004] ...
