Project Background

West exit project of Zhengzhou Railway Station (including Zhengzhou west station house, elevated waiting room, access tunnel), of which the total area of west station house is 12000m². The total construction area of the elevated waiting room is 6200m², and the access tunnel is 2500m.

Solution

This system comprises a central monitoring station, field controllers, auxiliary monitoring subsystems (e.g., HVAC monitoring subsystem, low-voltage power distribution intelligent monitoring subsystem), sensors, actuators, and a communication network.

The communication network consists of a central management network and a monitoring network, both utilizing Ethernet and TCP/IP protocols. The management and monitoring networks enable seamless integration with no protocol conversion required, delivering plug-and-play simplicity, high efficiency, and mission-critical reliability.

Highlighted Benefits

The central monitoring station management network has a dual Ethernet structure. The monitoring network adopts comprehensive cabling technology, consisting of trunk network and work area networks. The trunk network adopts multi-mode optical cable to form a fibre-optic ring industrial Ethernet network with self-healing function, connecting the central monitoring station and the work area network distributed in the field. The relatively concentrated area of station house electromechanical equipment forms a regional monitoring network, which consists of industrial Ethernet switches, communication adapters, UPS, distribution frames, etc. The DDC, monitoring subsystems and intelligent controllers are accessed in the vicinity, and the monitoring subsystems can adopt field bus, such as the intelligent monitoring system of the substation adopts RS-485 bus.
