Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0023] Such as figure 1 as shown, figure 1 It is a flow chart of the data processing method provided by the embodiment of the present invention. The data processing method includes the following steps:

[0024] S110. The TCN backup gateway device monitors the life signal sent by the TCN master gateway device.

[0025] S120. If the TCN backup gateway device determines that the life signal has not changed within the preset time, it converts the received data stream according to the pre-stored MVB protocol and WTB protocol.

[0026] In the data processing method provided by this embodiment, the TCN backup gateway device monitors the life signal sent by the TCN main gateway device. If the TCN backup gateway device determines that the li...

Abstract

The invention provides a data processing method, a TCN (Train Communication Network) standby gateway device and a data processing system. The data processing method comprises steps: the TCN standby gateway device monitors a life signal sent by a TCN main gateway device, if the TCN standby gateway device judges the life signal in a preset time does not change, conversion processing is carried out on a received data flow according to a pre-stored MVB (Multifunction Vehicle Bus) protocol and a WTB (Wire Train Bus) protocol, and thus in a condition in which the TCN main gateway device stops working as failure or other situations happen to the TCN main gateway device, the TCN standby gateway device replaces the TCN main gateway device to carry out conversion processing on the received data flow, communication between a WTB device and a MVB device on the train can be ensured, and the train can be ensured to operate normally.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data processing method, TCN standby gateway equipment and a data processing system. Background technique [0002] Train Communication Network (TCN for short), as the network communication standard of China's railway rolling stock, occupies a large proportion in the field of rail transit. According to the characteristics of train control, the TCN network includes two kinds of field buses: the Wire Train Bus (WTB for short) connecting each carriage and the Multifunction Vehicle Bus (Multifunction Vehicle Bus, MVB for short) connecting the equipment in the car. These two forms of buses defined by the TCN standard establish an open communication system, so that various types of railway rolling stock can be connected to each other, and equipment produced by different manufacturers can be interconnected. [0003] WTB network and MVB network are two independent communication s...
