Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031]The vehicle-mounted T-BOX can also be called a vehicle box, and its main function is: when the user sends a control command through the mobile APP, the background system will send a monitoring request command to the vehicle-mounted T-BOX. After the vehicle T-BOX receives the monitoring request command, it sends a control message corresponding to the monitoring request command to the corresponding components in the vehicle through the controller area network (CAN) bus to realize the control of the vehicle , and feed back the control results to the APP on the mobile phone. In this way, users can remotely start the lights, turn on the air conditioner, adjust the s...

Abstract

An embedded multimedia device and communication equipment for vehicle-mounted remote communication processor are provided. The embedded multimedia device is applied to the communication equipment of a vehicle-mounted remote communication processor T-BOX and comprises a startup disk partition, a high-reliability disk partition and a user data disk partition, and the startup disk partition stores boot program of the vehicle-mounted T-BOX in a manner of storing one bit data in each unit storage space. The high-reliability disk partition adopts mode of storing one bit of data in each unit storage space to store initialization information of hardware equipment included in the vehicle-mounted T-BOX and configuration file of the vehicle-mounted T-BOX. The user data disk partitions are used for storing data of application programs installed in the vehicle-mounted T-BOX to reduce cost of the storage module of the vehicle-mounted T-BOX on the premise of meeting high storage capacity and data reliability of the vehicle-mounted T-BOX.

Description

technical field [0001] The present application relates to the field of storage technology, in particular to an embedded multimedia device and a communication device for a vehicle-mounted telematics processor. Background technique [0002] With the development of Internet technology, the Internet of Vehicles system has been widely used. The Internet of Vehicles system consists of four parts, namely the host, the vehicle telematics box (T-BOX), the mobile phone application (APP) and the background system. The vehicle T-BOX is an important part of the vehicle network system, and is mainly used to realize the control of the vehicle by the background system or the APP on the mobile phone. [0003] The vehicle-mounted T-BOX mainly communicates with the background system or the APP on the mobile phone through the internal communication device. In the prior art, in order to ensure the reliability of the data in the vehicle T-BOX, please refer to figure 1 , the communication devic...
