Charging pile and data transmission method and system for new energy driverless vehicles

Abstract

A charging pile and data transmission method and system for new energy driverless vehicles are provided. The charging pile comprises a charging pile body and a charging gun, the charging gun is connected with the charging pile body through a cable, the charging gun is provided with a charging interface and a data input interface, and a charging module, a communication module and a data output interface are arranged in the charging pile body. As after the charging gun is connected to a new energy driverless vehicle, the charging pile establishes an electricity transmission channel through the charging interface and the charging module and establishes a data channel through the data input interface, the communication module and the data output interface, it is possible to acquire data stored in a vehicular hard disk drive of the new energy driverless vehicle during charging of the new energy driverless vehicle; after the data are captured by the charging pile, the data are transmitted to a server of a driverless vehicle cloud platform at high speed through optical fibers; compared with the prior art, the charging pile and the data transmission method and system have the advantages that data transmission efficiency is higher, the cost is lower, storage space of the vehicular hard disk drive can be released in time, backup is complete, and mass data acquired by new energy driverless vehicle sensors are stored.

Description

technical field [0001] The invention relates to the field of unmanned driving technology, in particular to a new energy unmanned vehicle charging pile and a data transmission method and system. Background technique [0002] Unmanned driving technology is the integration of multiple technologies. The unmanned driving system needs to integrate multiple functional modules to achieve path planning, obstacle avoidance, navigation, traffic signal monitoring, etc. Therefore, the sensors of the unmanned driving system include long-range radar, Lidar, short-range radar, camera, ultrasonic, GPS and gyroscope, etc., using these sensors, unmanned vehicles will collect massive data per second, and the unmanned driving cloud platform uses these data to continuously improve the driving performance and production of unmanned vehicles. Make a better map. At present, how to upload these data to the server of the unmanned vehicle cloud platform is an urgent problem to be solved. [0003] The...

Problems solved by technology

[0003] The existing method is often to manually copy the massive data collected by the unmanned vehicle stored on the on-board hard disk to the computer by unloading the on-board hard disk every day, and then upload it to the server of the unmanned vehicle cloud platform. Low, and disassembling the hard disk every day is easy to cause damage to the hard disk

Using wireless communication network for transmission is also a feasible method, but the data bandwidth of wireless communication network is often small. For example, the speed of 4G network is only 100Mbps, and it takes a long time to upload massive data, and the data transmission efficiency is low.

Moreover, in places where the wireless communication network is not covered, data may not be uploaded normally, and data leakage may occur.

In addition, using a wireless communication network to upload data, for example, using a 4G network to upload data, uploading massive data often requires a relatively large fee
