The product is used in railway passenger car. An intelligent integrated control cabinet with functional units :power conversion control, air conditioning unit control, battery undervoltage protection, lighting control, and networking communication etc.
The control unit of the electrical integrated control cabinet is composed of the core controller(PLC) and the information display touch screen
1. PLC is the abbreviation of Programmable Logic Controller. It automatically controls the entire electrical system, detects and analyzes the parameters of the electrical system in real time, automatically handles faults, realizes man-machine dialogue through the display touch screen, and responds to the display touch screen input Commands, parameters, fault information, running records are displayed on the touch screen, etc.
2. The display touch screen is a kind of micro programmable terminal, which adopts a liquid crystal display touch screen, which has character type and image type display, and communicates with the peripheral interface of the PLC through the communication interface. The main functions are on-site parameter setting, power conversion, human control of the operating conditions of functional units such as air conditioning units, display of operating parameters, real-time display of the operating status of each functional unit, and real-time reporting of failure phenomena.
