Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is a part of embodiment of the present utility model, rather than all implement
Example.Based on the embodiment in this utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment for obtaining, should all belong to the scope of this utility model protection.
CBTC (communication-based train control system) and TBTC (are based on the Train Control of track circuit by this utility model
System) carry out organic combination and Interface design, it is ensured that the normal fortune of train is not interfered with during any set of system failure
OK, due to complete isomery and hot backup redundancy between the two, the reliability of system is substantially increased,
As shown in figure 1, the system is made up of CBTC equipment with TBTC equipment, both shared ATS and interlock device.CBTC rails
Other equipment and TBTC trackside equipments independently work, and each provide the mode of mobile authorization information and speed code to control row
Car.In CBTC equipment wireless network using two sets different wireless system Wlan and LTE, CBTC by wireless red blue net and
CBTC is vehicle-mounted to carry out Train Control information exchange.TBTC carries out Train Control information exchange by track circuit with TBTC is vehicle-mounted.
CBTC mobile units and TBTC mobile units carry out ATP protection to train using device as shown in Figure 2, CBTC and
The vehicle-mounted respective offer EB contacts of TBTC, and vehicle EB loops are linked, when two sets of systems all export EB, train just performs urgent system
It is dynamic.The vehicle-mounted offer FSB contacts of TBTC, CBTC systems provide another EB contact, and link vehicle FSB loops, when CBTC systems
During system output EB, the FSB of TBTC systems output just can be performed by vehicle.
Train auxiliary drive section carries out the switching of the vehicle-mounted ATO of CBTC vehicle-mounted ATO and TBTC using device as shown in Figure 3,
Train operation is controlled by the vehicle-mounted ATO of CBTC during normal work, when CBTC mobile units complete failure or CBTC output brake hards
Or the vehicle-mounted ATO for automatically switching to TBTC is controlled train operation by CBTC-ATP/ATO patterns when unavailable.
The input/output interface of train adopts automatic control mode.Vehicle input such as driving model, vehicle door status and ATC cut
Except etc. state parallel acquisition is carried out using device as shown in Figure 4.Semiotic function is exported, such as traction braking order, switch gate order,
Two sets of systems are exported simultaneously, but are switched over by switch unit as shown in Figure 5.Under system health, CBTC vehicle-mounted work
Make junction closure, drive the relay in switch unit, vehicle receiver to command function to come from CBTC vehicle-mounted.When CBTC cars
