Problems solved by technology

In the above control mode based on the activation of a single gateway, once the redundant switching of the gateway occurs, the probability of the initial operation of the gateway is 100%, which makes the train-level network communication interrupted, resulting in the disconnection of the main circuit breaker of the train and the lowering of the pantograph.

Embodiment Construction

[0036] The following further describes the present invention with reference to the accompanying drawings of the specification and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0037] Such as figure 1 As shown, the gateway redundancy control method in the TCN network of this embodiment includes:

[0038] 1) Two mutually redundant gateway devices are set up in each locomotive in advance, and the gateway devices are configured to simultaneously serve as WTB bus management devices and MVB bus management devices; the two gateway devices are respectively configured as MVB bus master devices and MVB bus Standby main equipment;

[0039] 2) When the locomotive is powered on, the redundantly configured MVB bus master device and MVB bus backup master device of each locomotive will perform TCN initial operation, so that the MVB bus master device and the MVB bus backup master device are both in the WTB bus activation work status;

Abstract

The invention discloses a gateway redundancy control method and device in a TCN (Train Communication Network). The method comprises the steps of 1), setting two gateway devices in each locomotive in advance, wherein each of the two gateway devices is configured with an MVB (Multifunction Vehicle Bus) bus master device and an MVB bus backup master device; 2), carrying out TCN initial operation by the MVB bus master device and the MVB bus backup master device when each locomotive is electrified; 3), screening data of the MVB bus master device as WTB (Wire Train Bus) bus effective data; 4), switching to the backup master device when a fault occurs in the MVB bus master device and maintaining the WTB data if the initial operation is carried out. The device comprises a gateway configuration module, a double-gateway activation control module, a double-gateway communication control module and a redundancy switch control module. According to the method and the device, the operation state of each locomotive is prevented from being influenced when the gateway is switched; the reliability of the TCN is improved; and the method and the device have the advantages of simple control method, low required cost and high control realization efficiency.

Description

Technical field [0001] The invention relates to the technical field of electric locomotive control, in particular to a method and device for controlling gateway redundancy in a TCN (Train Communication Network) network. Background technique [0002] In AC drive electric locomotives, the gateway unit adopts dual-gateway redundancy configuration to improve operational reliability, but currently it is usually based on a single-gateway activated control mode, that is, the main gateway device is in working state during normal operation and the standby gateway is in sleep mode. Status, when the main gateway device fails, control to switch the backup gateway. Since only one gateway device becomes a WTB (Wire Train Bus) bus node during normal operation, when the gateway is redundantly switched, the dormant gateway will join the WTB bus and cause the TCN to operate initially. [0003] The initial operation of the gateway is a necessary process for the reconfiguration of the locomotive WTB ...
