Distributed train operation control system and control method

Abstract

The invention discloses a distributed train running control system in the field of commanding and dispatching of the railway running train and a control method thereof. The technical scheme is as follows: the distributed train running control system comprises an execution layer, a section control layer, a line control layer and a railway network control layer from top to bottom; the adjacent layers have the mutual-communication function; the lower layer provides the processed state information for the upper layer; and the upper layer provides the control policy for the lower layer according to the processed state information. The distributed train running control method is as follows: after the control cycle is started, the corresponding knowledge base is searched according to the lower-layer information, the information of an intelligent agent which is adjacent to the layer and the upper-layer information; whether the corresponding control rules exist in the knowledge base or not is judged; if so, the control policy is made directly; if not, the learning control is carried out so as to control the rules; finally, the control policy is executed. In the invention, the ability limit and the real-time limit of the traditional running-train commanding system are overcome, and the flexibility, the real-time function and the optimal control of the running train are ensured.

Description

technical field [0001] The invention belongs to the field of railway traffic command and dispatch, and in particular relates to a distributed train operation control system and a control method. Background technique [0002] At present, my country's traffic command automation system is almost all based on the principle of centralized control. In this system, the control and decision-making capabilities and information processing capabilities are all concentrated in the main engine. A decision made by the host. The performance of the system will mainly depend on the capability and efficiency of the host, and each extension will only passively complete the decision-making plan issued by the host. This centralized control system has many defects. Under a certain train flow rate, the control area of ​​this system or the control flow rate under a certain control area has an upper limit, and in the case of a large control range and a large train density, this system It will be di...

Problems solved by technology

Applying the idea of ​​layered and hierarchical optimization of large-scale systems, using agent technology to build a distributed train operation control system; at the same time, based on this system, a distributed train operation control method is proposed to solve the current railway train operation scheduling system. In the case of large control range and high train density, the problem of real-time decision-making cannot be satisfied
