Track traffic communication system and data processing method

Abstract

The invention provides a track traffic communication system and a data processing method. Information, acquired by a detection device, of terminal equipment is received through a controller, and the information is converted into a CAN data signal, and, after the CAN data signal is sent to a communication gateway, the communication gateway converts the CAN data signal into a corresponding mobile network data signal and sends the mobile network data signal to cloud equipment through a mobile communication network; or the communication gateway receives a mobile network data signal, sent through a mobile communication network, of cloud equipment, converts the mobile network data signal into a corresponding CAN data signal according to a prestored format conversion protocol stack and sends the CAN data signal to the controller so that the controller sends the CAN data signal to the terminal equipment. Data interactions and information processing are performed in real time through the mobile communication network between the terminal equipment on a rail vehicle and the cloud equipment, and the data transmission capacity and data processing efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a rail transit communication system and a data processing method. Background technique [0002] At present, each terminal device inside a rail vehicle is connected to the vehicle network system in the form of a Controller Area Network (CAN) bus. The CAN bus has a high transmission rate and can provide up to 1Mbit / s data transmission within 40 meters. Speed, with automatic error detection mechanism and automatic retransmission function, the terminal equipment can exit the bus when the error is serious, so that the network performance will not be affected by bad nodes, the CAN bus can dynamically load nodes, so that the entire system does not need to stop for a single node, Can greatly reduce the loss of downtime. Therefore, the CAN network is a relatively general and highly anti-interference industrial network, which is often used in the device-level network in the vehicle ...

Problems solved by technology

[0004] With the development of informatization and intelligentization of locomotives and vehicles, the vehicle-mounted network system has put forward higher and higher requirements for network data throughput and transmission rate. However, due to the limitations of cables and communication methods in the The distance between them is generally very short, the amount of transmitted data is generally very small, and it is impossible to realize the transmission of large data of equipment information. Therefore, the data communication processing capability of the existing technology has certain limitations.
