Abstract

The invention discloses a vehicle-mounted communication terminal. The vehicle-mounted communication terminal includes a battery, a power management unit, a microcontroller, a switching unit for switching power supplied by the battery or an external power supply, and a normal fire detection device for detecting the voltage of the normal live line unit; wherein, the power management unit converts the power output by the battery; the microcontroller compares the voltage of the normal live line with the preset voltage, and controls the switching unit to switch when the voltage of the normal live line is less than the preset voltage, and the battery controls the The vehicle communication terminal supplies power. The technical scheme of the invention can realize the long-time standby of the vehicle communication terminal.

Description

technical field [0001] The invention relates to the technical field of vehicle communication, in particular to a vehicle communication terminal. Background technique [0002] While the state's support for new energy vehicles has increased, supervision has also increased, requiring new energy vehicles to have a communication terminal to collect and save key state parameters of the vehicle and system components and send them to the platform. [0003] The vehicle-mounted communication terminals currently on the market are generally composed of a GPS module, a communication module, a microcontroller and related interfaces. The application direction of each manufacturer is different, and their respective architecture combinations are not the same. Some may not have a GPS module, and some may not be connected to the vehicle bus system. [0004] However, none of the technical solutions here has a back battery, and it is impossible to realize the long-term standby of the vehicle co...
