Problems solved by technology

The traditional transmission method may lead to problems such as loss of download records when the transmission is interrupted, and missing data during transmission when the signal is poor
[0003] For example, the authorized publication number is CN 107426270A, which discloses a method for continuous transmission of data from vehicle remote monitoring terminals, which is mainly used in the process of uploading data to the server of vehicle terminals. Guarantee the integrity and correctness of the data, and at the same time, the method of judging whether it is a continuation transmission is cumbersome, which is not conducive to improving the transmission efficiency

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0024] This embodiment provides an unmanned vehicle route data transmission system with breakpoint resume transmission, including a server and a vehicle-mounted terminal. The vehicle-mounted terminal receives the route data sent by the server, and at the same time collects road condition information and vehicle condition information when the vehicle is driving and uploads them to the server. , the server and the vehicle terminal take turns sending and receiving data as the sending end and the receiving end. The sending end includes a data block module, a data sending module and a signa...

Abstract

The invention discloses an unmanned vehicle route data transmission system with breakpoint continuous transmission and method thereof. The system comprises a server and a vehicle terminal; the vehicleterminal receives route data sent by the server, and collects road condition information and vehicle condition information while a vehicle is traveling and uploads the information to the server; theserver and the vehicle terminal transmit and receive the data as a transmitting end and a receiving end in turn; the transmitting end comprises a data block module, a data transmitting module and a signal detection module; and the receiving end comprises a data receiving module and a data verification module. According to the unmanned vehicle route data transmission system with the breakpoint continuous transmission provided by the invention, the continuity and the real-time performance of route data transmission in the travelling process of the vehicle can be effectively ensured, the data transmission time is shortened, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of unmanned vehicle data transmission, in particular to an unmanned vehicle route data transmission system and method thereof. Background technique [0002] At present, in the route management of unmanned vehicles, vehicle terminals and servers need to transmit data in real time. The vehicle terminal uploads the information collected along the way to the server, and the server plans and adjusts the route of the vehicle accordingly and transmits it to the vehicle. In mobile communication, the signal fluctuates greatly. In tunnels and forests, there may be no signal and the transmission is interrupted. Retransmit after the network signal is restored. The traditional transmission method may lead to problems such as loss of download records when the transmission is interrupted, and missing data during transmission when the signal is poor. [0003] For example, the authorized publication number is CN 107426270A, which di...
