Problems solved by technology

At present, the basic research and development of TCN technology in China is much behind that of foreign countries, especially for high-end core equipment such as TCN gateways. Due to technical difficulties and long research and development cycles, they have always relied on imports. The lack of this equipment restricts the localization of TCN network communication technology. The key factor

Embodiment Construction

[0047] As shown in Figure 1 to Figure 12. A TCN gateway and its communication method. These include:

[0048] 1. Gateway hardware system

[0049] The gateway hardware system is the operating platform of the TCN protocol stack software, which is composed of the MCB module, the WTB module, and the PW power supply module. The MCB module is composed of a central processing unit and an MVB unit. The central processing unit runs TCN protocol stack software and user-level application software under the support of the Nucleus real-time operating system. The MVB unit is responsible for receiving and sending MVB data and supporting the underlying functions of the link layer. The WTB module runs the WTB link software, is responsible for the sending and receiving of WTB data and supports the underlying functions of the WTB link. Among them, the WTB module and the MCB module are connected through an internal parallel bus for data exchange between the two modules.

Abstract

The utility model discloses a TCN gateway communication equipment, which is characterized in comprising a MCB module and a WTB module, wherein the MCB module comprises a 32-bit CPU, a MVB unit, a MVBCS01 protocol controller and an external periphery circuit. Supported by a Nucleus real-time operating system, a hardware platform is provided for operating a TCN net management software, a real-time protocol stack software and a MVB link protocol software. The WTB module comprises an 8-bit CPU processor, a WTBC protocol controller and an external periphery circuit, providing operating platform of the WTB link software. Data communication of process data of a destination port and a WTB source, monitoring data and / or message data of WTB is performed via the internal parallel bus between the MBC module and the WTB module. The utility model has the advantage of conformity to international train communication network TCN standard IEC61375-1, the most advanced equipment in TCN network and extensive application range in railway vehicle.

Description

Technical field [0001] The present invention relates to the international train communication network TCN standard IEC61375-1, which is the highest level of communication equipment in the TCN train communication network. It is downward compatible with MVB vehicle bus and WTB train bus, and is widely used in high-speed trains, EMU EMUs, and DMU EMUs. , Trams, subways, passenger cars and other rail vehicles. technical background [0002] The international train communication network TCN standard IEC61375-1 was developed specifically for rail vehicles after fully considering the actual application requirements of trains and extensively soliciting the opinions of railway manufacturers and operators from all over the world. It is the current domestic and foreign train network The mainstream of communication technology is also the current network communication standard recommended by Chinese railways. At present, the basic research and development of TCN technology in China lags far be...
