What is the Railway Train Dispatch Command System (TDCS)?

Dispatch centralization is the technical equipment of the railway dispatching center to centrally control the railway signal equipment in a certain section, and directly direct and manage the operation of the train.

CTC system: It is the technical equipment that the dispatch center centrally controls the signal equipment in a certain section and directly directs and manages the operation of the train.

Railway Administration TDCS (Train Dispatching and Control System) is an information system used to manage and control railway transportation. In addition to the above functions, TDCS of the Railway Bureau can also provide functions such as train operation data analysis, operation adjustment and emergency handling to improve the efficiency and safety of railway transportation management.

The difference and connection between TDCS and CTC

1. tdcs is the basis of ctc, and ctc is the functional enhancement and extension of tdcs. Tdcs provides ctc with important information such as train operation plan, train tracking status, signal device status, etc. Ctc puts forward higher requirements for the reliability of tdcs.

2. Among them, TDCS is the basis of the railway transportation dispatch command system, with real-time monitoring and train operation plan (operation diagram) management as the functional body; while CTC is the functional enhancement and extension of TDCS, with station control, automatic map-based routeing and driving command automation as the functional body. .

3. CTC: CenTralized Traffic Control System, scheduling centralized control system. Centralized dispatching is the technical equipment used by the railway dispatching center to centrally control the railway signal equipment in a certain section, and directly direct and manage the operation of trains.

4. Different refers to the difference: the CTC system refers to the technical equipment directly commanded and managed by the dispatch center for the operation of the train, not the CTC system, which is the dispatching command management system covering the whole road.

The predecessor of the train dispatch command system is

1. The centralized dispatch system. According to the official website of China National Railway Group Co., Ltd., the dispatch centralized system refers to the system that uses computer technology and communication technology to centrally control and manage train operation.

2. Tietong was originally a part of the railway and belonged to the electrical system. Later, due to the reform of state-owned enterprises, it was separated from the original railway and handed over to the State-owned Assets Supervision and Administration Commission for management.

3. TDCS (Train Dispatch Command System) is networked by China Railway, which is equipped with extremely strict anti-virus and firewall settings. IP addresses and passwords are frequently changed, and it is responsible for the implementation of all dispatching schemes.

4. The developing train control system will become an automated system for comprehensive business management integrating train operation control, driving dispatch command, information management and equipment detection.

5. At present, the Hewu and Hening passenger special lines have realized the organic integration from the main wired communication mode to the wireless communication mode and the wired communication mode.
