Abstract

The invention discloses a power-off control module for a communication unit of a vehicle-mounted communication terminal of an intelligent automobile, and the module comprises a main control unit whichis powered by a second power supply unit, and outputs a power-off instruction to a first time-delay circuit if the main control unit receives a fault signal of the communication unit and executes a fault processing program of the communication unit and then the communication unit still fails; a first time delay circuit which is respectively connected with a second time delay circuit and the firstpower supply unit, and is suitable for enabling the first power supply unit to output and turn off after executing the first preset time delay, and enabling the second time delay circuit to start thesecond preset time delay; the second time delay circuit which is connected with the first power supply unit and the vehicle-mounted power supply, and is suitable for enabling the first power supply unit to output and start after executing second preset time delay; a vehicle-mounted power supply which is suitable for directly starting the first power supply unit or starting the first power supplyunit through the second time delay circuit; and a first power supply unit which is suitable for supplying power to the second power supply unit and the communication unit. The short-time outage automatic recovery function of the communication unit of the vehicle-mounted communication terminal can be achieved, and compared with the prior art, the production cost can be remarkably reduced.

Description

technical field [0001] The invention relates to the field of smart cars, in particular to a power-off control module for a communication unit of a vehicle-mounted communication terminal (TBOX) of a smart car. Background technique [0002] Today in the 21st century, with the rapid development of communication technology, cars, which are isolated islands of information, have gradually established connections with the outside world. According to the requirements of the national standard "Technical Specifications for Electric Vehicle Remote Service and Management System" (GB / T32960), vehicles (especially smart cars) need to actively upload data to the vehicle network platform. [0003] Therefore, installing a vehicle communication terminal (TBOX) has become an increasingly urgent demand. The connected car installed with the on-board TBOX has functions such as information interaction and vehicle control, and has the characteristics of never-ending power supply. As the communica...
