The dispatching centralized system is used for carrying out centralized control on train operation, is constructed on the basis of a train dispatching command system and consists of a railway bureau and a station. The dispatching centralization not only realizes all functions of a train dispatching command system, but also realizes the functions of train marshalling information management, shunting operation management, comprehensive maintenance management, manual and planned automatic selection and arrangement of train/shunting routes, decentralized autonomous control and the like.
The train control center is a train control safety device arranged at each station or relay station, is connected with a track circuit, a computer interlock, a temporary speed limit server, other station train control centers, a responder ground electronic unit (LEU), a CTC and signal centralized detection, and realizes the functions of controlling the track circuit, an active responder, the interval direction, the block and the like. The train control center generates relevant empty train information such as access, temporary speed limit and the like according to the dispatching command, the access state, the line parameters and the like, and dynamically transmits the information to the train through the active transponder and the track circuit, thereby realizing the dynamic control of the train operation. The train control center comprises a safety host unit, a communication interface unit, a driving acquisition unit, an auxiliary maintenance unit, an inter-station safety data network communication unit and a redundant power supply unit. The train control center can simultaneously control 100 track circuit sections, 16 LEU devices, 30 signal machines and 30 blocking partitions to the maximum extent, simultaneously process 30 train routes and 8 interval lines to the maximum extent, and simultaneously control center interfaces with 4 adjacent stations and 6 relay station train control center interfaces to the maximum extent. In this embodiment, the row control centers include a row control center 1 series and a row control center 2 series. The system 1 and the system 2 can work synchronously, and can be switched between the system 1 and the system 2 through the switching handle after the system 1 and the system 2 are synchronized under normal conditions, so that the speed limit command and the route information cannot be lost in the switching process, and signals and track display, track circuit coding and LEU output are not influenced.
The dispatching concentration system comprises a first autonomous machine and a second autonomous machine. The autonomous machine is a core device of a CTC station, the hardware of the autonomous machine selects a special industrial computer device, and the autonomous machine has the following functions in the CTC: receiving a train operation plan of a dispatching center, generating a route sequence in due time, and automatically triggering a driving interlocking system to execute according to conditions such as plan indication, train position and the like; receiving a shunting operation plan, generating a route sequence in due time, and automatically triggering a driving interlocking system to execute according to a wireless application of a shunting unit and a train position; receiving an access sequence operation instruction of a dispatching center and a station attendant, and modifying a formed access sequence to be executed; receiving direct control operation instructions of a dispatching center and a station attendant, and driving an interlocking system to execute after confirming no conflict after checking with a train plan and an interlocking relationship; analyzing the representation information of the signal equipment, tracking the state of the route, confirming the integrity of the route and the correctness of the signal, and processing and alarming abnormal conditions; tracking the train number, checking the train number in a wireless manner, and confirming the train number manually; exchanging station yard real-time information, train number information, train plan and actual arrival and departure information with adjacent station autonomous machines; the number of the train at the station and the forecast of the arrival situation can be automatically adjusted; receiving dispatching commands, road tickets, driving certificates and the like issued by a dispatching center, transmitting the dispatching commands, the road tickets, the driving certificates and the like to locomotive drivers through wireless interfaces at proper time, and then transmitting the signing information of the drivers; receiving a road ticket, a driving certificate and the like issued by a station attendant, transmitting the road ticket, the driving certificate and the like to a locomotive driver through a wireless interface at a proper time, and then transmitting the sign-in information of the driver; the wireless access is automatically announced. In the embodiment of the disclosure, the first autonomous machine and the second autonomous machine are cross-connected with the train control center 1 series and the train control center 2 series through the RS-422 serial ports.
It should be noted that RS-422 is a four-wire interface that uses separate transmit and receive channels, without having to control the direction of data, and any necessary signal exchanges between devices can be either software (XON/XOFF handshaking) or hardware (a single pair of twisted-pair wires). The maximum transmission distance of RS-422 is 4000 feet (about 1219 meters) and the maximum transmission rate is 10 Mb/s. The length of the balanced twisted pair is inversely proportional to the transmission rate, and the maximum transmission distance is reached below the rate of 100 kb/s. The highest rate of transmission is only obtained at short distances. RS-422 allows to connect multiple receiving nodes on the same transmission line, up to 10 nodes, i.e. one Master (Master) and the rest Slave (Slave). Therefore, for the train control center with the train control center 1 series and the train control center 2 series, the cross interconnection with the dispatching concentration system including the first autonomous machine and the second autonomous machine can be realized.
In this embodiment, the dispatch concentration system further includes a first optoelectronic isolator group and a second optoelectronic isolator group, specifically, the first optoelectronic isolator group includes a first optoelectronic isolator and a second optoelectronic isolator, and the second optoelectronic isolator group includes a third optoelectronic isolator and a fourth optoelectronic isolator. A photo isolator, which is called an optocoupler for short, is a device that transmits an electrical signal by using light as a medium, and generally a light emitter (an infrared Light Emitting Diode (LED)) and a light receiver (a photosensitive semiconductor tube) are packaged in the same package. When the input end is electrified, the light emitter emits light, and the light receiver receives the light, then photocurrent is generated and flows out from the output end, thereby realizing 'electro-optic-electro' conversion. The photoelectric coupler using light as medium to couple the input signal to the output has the advantages of small size, long service life, no contact, strong anti-interference capability, insulation between output and input, unidirectional signal transmission, etc.
The first autonomous machine is connected with the first photoelectric isolator group through an RS-422 serial port and then connected with the RS-422 serial ports of the train control center 1 series and the train control center 2 series to realize cross connection; and the second autonomous machine is connected with the second photoelectric isolator group through an RS-422 serial port and then connected with the RS-422 serial ports of the train control center 1 series and the train control center 2 series to realize cross connection.
