Abstract

The invention discloses locomotive network control test platform based on TCN. It includes WTB bus board card, MVB bus board card, CPU board card, power board card, back board. The WTB, MVB, CPU board cards are connected with back board bus. The power board card is used to supply working voltage for them. The first one is used to collect and transmit data for train bus device. The second one is used to collect and control the data. And the third one is used to do center processing the data and create ETHERNET, RS232, and RS485 monitoring controlling data flow. The platform satisfies international standard TCN network technique, has the advantages of new design, high reliability, suiting for applying in our country rolling stock and electrical plant industry fields etc.

Description

technical field [0001] The invention relates to the electric locomotive network control based on the TCN standard in the railway industry, in particular to a TCN locomotive network control test platform used for field network equipment tests. Background technique [0002] In my country, electric locomotives have always adopted a centralized control method, that is, the collection and control of all signals on site need to be connected to the centralized control computer through hard wires. Due to the large number of wires, the probability of failure at the contacts is very high. Therefore, the system The reliability is very low, the failure rate is high, and the maintenance is very difficult. With the rapid development of foreign advanced TCN network control technology, my country's electric locomotives have also begun to adopt TCN technology. [0003] IEC61375-1 "Train Communication Network" (TCN standard for short) is an international standard and also the standard of my c...
