[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 requ

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.
