Abstract

The invention provides a rail transit-based control method and apparatus. When an event occurring in a rail transit running process is detected, a message corresponding to the event is obtained; according to an object of the event, a custom state table is queried to obtain a standard state table corresponding to the object; according to a source mode in which the object is currently, the standardstate table is queried to obtain a core state table corresponding to the source mode; and finally according to the message, the core state table corresponding to the source mode is queried to obtain atarget mode and a control method corresponding to the message, thereby executing the control method to control the object to be in the target mode. The core state table is used for recording a corresponding relationship among the message, the target mode and the control method, and the custom state table is used for recording the standard state table corresponding to each mode of the object, so that the complex control method is subdivided, control logic is clearer, and the technical problems of complex control method and relatively high maintenance cost in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a rail transit-based control method and device. Background technique [0002] In the process of rail transit operation, in order to ensure the safety of operation, it is necessary to control various systems such as trains, signals, and communications. In the prior art, the operation can be controlled by the control software, but due to the complexity of the rail transit system, some loopholes may appear in the control software during software testing. If the loopholes found in software testing cannot be corrected in time, it may cause irreversible harm in rail transit operation. [0003] Although there are control software developed in various ways such as singleton mode, adaptation mode, state mode, and strategy mode in the prior art, the control logic in these control software is complicated, which leads to bug fixes and later maintenance. , For example, when adding n...
