Application of lambda architecture in intelligent operation and maintenance system of rail transit vehicles

Abstract

The application of lambda architecture in the intelligent operation and maintenance system of rail transit vehicles is to realize the intelligent operation and maintenance system, effectively reduce costs, improve safety and improve service quality. This application will be mainly used in train control system, track circuit protection system, radio communication network, etc. The main components are: 1) the central controller is composed of a computer with high-performance CPU (central processing unit), high-speed memory (random access memory) and a powerful network interface card; 2) A large number of distributed controllers are connected to the central controller through LAN or WAN; It adopts advanced technology to provide reliable performance and high efficiency. The main features of the system are as follows: it can be applied to various transportation systems, including railways, subways, trams, etc. It can be applied to various transportation systems, including railways, subways, trams, etc. It has high reliability because it takes into account many factors, such as traffic conditions (e.g., number of passengers), weather conditions (e.g., temperature) and other factors related to operation.
