Problems solved by technology

[0006] In the 20th century, with the wide application and popularization of various new technologies, the traditional control system has been unable to meet the needs of modern industrial efficiency, and the demand for control systems in the market is also increasing
Before the rise of non-relational databases (NoSQL, Not Only SQL), relational databases were the main means of storing historical data. However, facing the storage of massive historical data, relational databases have been unable to meet the high concurrency and high real-time requirements of SCADA systems. , high reliability requirements

Embodiment Construction

[0032] According to the functions of the man-machine interface module and combined with the needs of users, the module is mainly divided into three sub-modules, which are project management module, screen editing module and user management module. The project management module is used for engineering personnel to create, edit and deploy projects, etc., to facilitate project management; the screen editing module provides a configuration interface for configuration operations, mainly to complete the dynamic construction of field diagrams; the user management module is to strengthen The security operation of the configuration software provides the user login authentication function and the management of user rights.

[0033] When engineering personnel use the monitoring configuration software, they first enter the project management module through the login function provided by the user management module, and create a project in the project management module. After entering the s...

Abstract

The invention relates to an Internet of Things data acquisition and monitoring control system, and belongs to the Internet of Things field. The invention invents a method for designing and realizing small configuration software by means of SVG vector diagram, combines the configuration software with the traditional SCADA system structure, and realizes a visual new generation SCADA system with bothDT (Desgin Time) and RT (Run Time) states. Aiming at the requirement of real-time data processing by monitoring configuration software, a real-time data receiving and pushing function based on RabbitMQ in Ruby on Rails environment is designed. And an improved LZW algorithm is proposed to deal with the huge amount of historical data generated by SCADA system. The invention is of great significancefor the management and control of equipment and information of road networks, such as high-speed railway and urban railway stations.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, and in particular relates to a data collection and monitoring control system used in the railway industry. Background technique [0002] In recent years, the concept of Industry 4.0 has been proposed. It is the fourth industrial revolution centered on smart factories and smart manufacturing. It is the product of social needs and the continuous development of the Internet. The era of industry 4.0 has three notable features: intelligence, networking and informatization. It aims to realize the progress of modern science and technology. In today's competitive industrial environment, the efficiency and productivity of modern equipment can be improved through network and information technology. . Realizing the modernization and informatization of the SCADA (Supervisory Control And Data Acquisition) system is an important part of realizing Industry 4.0. [0003] The SCADA system is a process IoT ...
