Abstract
The utility model relates to dispatching order route number interval interlocking equipment. Main equipment is connected with a TDCS (Traffic Data Collection System) through two RS422 communication interfaces, and connected with a 2M transmission system through an E1 connecting wire; slave equipment is respectively connected with a dispatching order station adapter and a data receiving decoder through two RS422 communication interfaces, and connected with the 2M transmission system through an E1 connecting wire; and the main equipment and the series of the slave equipment form a token ring network through the 2M transmission system. The slave equipment transmits route number information of the data receiving decoder of each substation and the dispatching order signing information of the dispatching order station adapter to the main equipment, and then the main equipment transmits the information to the TDCS of a master station; the main equipment receives dispatching order information sent by the TDCS of the master station and sends the information to the slave equipment of each substation, and then the slave equipment sends the information to the dispatching order station adapter. The dispatching order route number interval interlocking equipment has the advantages that the centralized control, the centralized management and the centralized maintenance of dispatching order route number transmission can be realized; the use is convenient; and the equipment cost is saved.
Description
Technical field
The utility model relates to railway wireless train and transfers equipment; Be particularly related to the interval release-locking device of a kind of traffic order running number; Equipment is used for the occasion of the shared TDCS in a plurality of stations of a section, and TDCS (Train Operation Dispatching Command System) is the dispatch control management system that covers system-wide.
Background technology
At present, in China train dispatch radio communication system, the wireless dispatching command transfer system at each station of a section and running number are checked in the information transmission system, all need to be equipped with separately TDCS.So not only system architecture equipment cost and handling cost be than higher, and to the management of system, safeguard and bring inconvenience.
2.048Mbit/s PCM digital link transmission technology is very ripe at present, in railway communication network and public communication network, all is widely used.2.048Mbit/s PCM digital link transmission system abbreviates the 2M transmission system as.Therefore; The wireless dispatching command transfer system and the running number that PCM (PulseCodeModulation pulse-code modulation) digital link transmission technology are applied to each station of section are checked the information transmission system; System architecture equipment cost and handling cost will be reduced greatly, and convenient greatly management, maintenance to system.And the present domestic bibliographical information that this respect is not arranged as yet.
Summary of the invention
In view of the deficiency of existing equipment, the utility model provides a kind of traffic order running number interval release-locking device.This equipment utilization 2M transmission system; The traffic order running number transmission signals of a section is carried out the centralized control detection; Only use a TDCS to realize the traffic order and the running number transmission at all stations of this section; This equipment can be realized centralized control, centralized management and the centralized maintenance of traffic order running number transmission, has made things convenient for operation and maintenance, and practices thrift equipment cost.
The utility model is for realizing above-mentioned purpose, and the technical scheme of being taked is: the interval release-locking device of a kind of traffic order running number comprises main equipment and slave unit; It is characterized in that: main equipment is connected with TDCS through 2 RS422 communication interfaces, is connected with the 2M transmission system through 75 ohm of BNC type E1 connection leads; Slave unit is connected with the data sink demoder with traffic order station adapter respectively through 2 RS422 communication interfaces, is connected with the 2M transmission system through 75 ohm of BNC type E1 connection leads; Main equipment and a series of slave unit are formed token-ring network through the 2M transmission system; Utilize on-the-spot 2M transmission path; Through slave unit the traffic order of the running number information of the data sink demoder of each substation, traffic order station adapter is signed for information and send main equipment to; And then send the TDCS of main website to; Receive the traffic order information of the TDCS of main website transmission and send to each substation slave unit through main equipment, and then send to traffic order station adapter, realize the traffic order station adapter and the shared TDCS of data sink demoder at a plurality of stations with this; The occasion that can be used for the shared TDCS in a plurality of stations.
