Train Control System Based on Vehicle-Vehicle Communication

Product Introduction

Train control system based on vehicle-vehicle communication takes vehicle-mounted moving unit as the core, it realizes train operation control, breaks through the control mode of CBTC based on access and realizes intelligent operation control through two-way, high-capacity and high-speed vehicle-ground wireless communication, multi-sensor train speed positioning, autonomous collaborative moving block control technology, self-perception and independent decision making.


1) Higher performance. The onboard communication data flow directly reaching the control object is simplified to realize higher system performance and smaller operation intervals.

2) Higher reliability. The reduction of equipment reduces the failure rate. The fault of a single train signal system only affects the current and adjacent trains, while the fault of station equipment in traditional CBTC may affect the operation of all trains in the whole area.

3) Lower cost. Reduction of station equipment can minimize the cost for construction, commissioning, electricity and equipment space.

4) Easy construction and maintenance. Major system equipment is arranged on the train, which is convenient for system maintenance and greatly reduces the engineering difficulty of transformation line due to the independence of ground equipment. It can also realize return and bidirectional operation more easily.

5) Favorable for interconnectivity. Due to less vehicle-ground communication interface and independence of ground equipment, interconnectivity among different systems can be realized more easily.


Achieve a highly reliable, high-performance, integrated, small-sized safety computer platform. The real-time intelligence of the Ethernet bus and onboard platform can facilitate upgrading or expansion and realize interface compatibility of different operation modes such as C2+ATO and CBTC.
