Description

technical field [0001] The invention relates to a railway traffic communication control technology, in particular to a TCN-based multi-bus vehicle communication control module. Background technique [0002] Existing vehicle communication control modules or units based on the TCN network mainly adopt a chassis structure. To realize bus management and control functions, at least plug-ins such as power supply, processor, and bus manager must be used, which makes the system very complicated, high in cost, and high in power consumption. ,huge size. At present, similar products mainly have the following deficiencies: (1) The communication function is limited and only meets the basic functions of the TCN-based vehicle communication control module. There are no communication interfaces such as Ethernet and USB, and cannot meet the current situation that multiple field buses coexist in the vehicle at the same time. (2) The processing speed is slow. For th...

[0002] The existing vehicle communication control modules or units based on the TCN network mainly adopt a chassis structure. To realize bus management and control functions, at least plug-ins such as power supply, processor, and bus manager must be used, which makes the system very complicated, high in cost, and high in power consumption. ,Big size

At present, similar products mainly have the following deficiencies: (1) The communication function is limited and only meets the basic functions of the TCN-based vehicle communication control module. There are no communication interfaces such as Ethernet and USB, and cannot meet the current situation that multiple fieldbuses coexist in the vehicle at the same time. (2) The processing speed is slow. For the bus manager and vehicle control, the real-time requirements are extremely high, and it is difficult to meet the real-time communication and control requirements with tens of Mhz processors; (3) The storage space is too small. Due to the traditional NAND FLASH+SRAM design method, the capacity cannot be increased. Compared with fault diagnosis and recording, it cannot meet the existing requirements; (4) The power consumption is large and the volume is large due to the number of plug-ins. Many, and no power-saving design technology is used, which makes the power consumption large and the volume cannot be reduced; structurally, the chassis structure is adopted or even if it is modularized, it is evolved from the standard 3U and 6U plug-ins, which are bulky and heavy. It is inconvenient to install, and the removal of the plug-in is also extremely difficult
