Intelligent network remote terminal unit (RTU) system of electrified railway

Abstract

The invention discloses an intelligent network remote terminal unit (RTU) system of an electrified railway. The intelligent network RTU system is characterized by comprising an intelligent RTU, wherein the intelligent RTU comprises a master control communication plugin, a telecommand plugin, a remote control plugin and a telemetering plugin, the master control communication plugin is internally provided with a man-machine interface, an equipment management interface and a communication management interface, the master control communication plugin is communicated with all dispatching master stations through dual Ethernets, and the master control communication plugin is communicated with the telecommand plugin, the remote control plugin and the telemetering plugin through dual CAN (Controller Area Network)-BUS. The intelligent network RTU system is more beneficial to management and monitoring of remote measurement and control, and has the advantages of higher intelligent level, high performance, high stability and high operability.

Description

technical field [0001] The invention relates to the field of data acquisition and monitoring, in particular to an electrified railway intelligent network remote measurement and control terminal system. Background technique [0002] With the rapid development of electrified railways, the remote measurement and control terminal (RTU) has become more and more widely used, and more and more product types have been extended. On-duty creates conditions and enhances operational safety. The development of RTU must follow the rapid development of computer technology, network communication technology, sensor technology, and database technology. It is inevitable to further promote the popularization of RTU and the expansion of application fields. At present, many modern enterprises are faced with various problems such as geographical dispersion, massive information, and complex data acquisition environment. This is the broad application stage of remote measurement and control systems i...

AI Technical Summary

Problems solved by technology

[0003] 1. Electric remote measurement and control terminal products are relatively single-oriented, and their technical indicators are designed for specific occasions in specific fields, and the product versatility is poor

[0004] 2. Product function design mostly focuses on meeting the design requirements of the system as a whole, with relatively poor interoperability, relatively high requirements for operating personnel, complex management, and high labor costs

[0005] 3. The collection capacity of the system is limited. In some occasions with a large amount of data, multiple devices may need to be cascaded, and a large number of cascading methods will inevitably affect the overall stability of the system. The amount of information is huge and difficult to process.

[0006] 4. The measurement function is single, and the measurement and control terminal is only satisfied with the specific measurement function, and cannot realize the alarm processing of individual faults

Therefore, it is necessary to add a separate device to realize fault handling

[0007] 5. A large number of terminal equipment of railway equipment are placed outdoors, the working environment is harsh, the reliability requirements are high, and the requirements for anti-electromagnetic interference and electromagnetic compatibility are high

[0008] 6. High energy consumption
