ZPW-2000S Jointless

Track Circuit Equipment

ZPW-2000S Jointless Track Cicuit is a basic signalling safety equipment that uses the rail as the transmission medium.

Its major functions are as follows:

The block diagram of the track circuit system principle is as follows:

System Function

· Provide track section occupied/clear status information for the trackside signalling system.

· Broken rail detection (when a rail break occurs and results in an electrical open cricuit).

· Continuously transmit 18 types of real-time low-frequency control information to the onboard equipment.

ZPW-2000S equipment, developed by HollySys,

supports both communication coding and

conventional, and intercity railway lines.

01.\"2oo2×2\" Hardware Redundancy Structure

The system adopts a \"2oo2×2\" hardware redundancy structure, with indoor control units integrating two sets of CPUs. The confi gured

dual control units form a dual-machine operation and hot standby system, ensuring higher safety and reliability.

02.Double Safety Check

The system employs double safety check

technology with added internal check loops

between the sender and the receiver to double

check the frequency shift signal of the indoor

and outdoor loops. It can protect the crosstalk

of frequency shift signal, thereby improving the

safety of the system.

03.Outdoor Equipment Dual Isolation Redundant Protection

The outdoor equipment employs a dual isolation protection design. Auxiliary tuning units and tuning matching units are installed at the

mechanical insulation joints at both ends of the platform track. When the mechanical insulation is damaged or the tuning matching unit

malfunctions, this can ensure safe transmission of the outdoor frequency shift signal.

High Safety and Reliability

The system adopts intelligent remote maintenance technology, equipped with monitoring and diagnosis devices. It features indoor and

outdoor monitoring, visual display of station and equipment status, data and curve query, early warning of equipment abnormalities, fault area

diagnosis, on-site maintenance guidance, historical data playback, and centralized monitoring and communication. These functions enable

remote fault diagnosis and precise location of track circuit failures, enhance capabilities in intelligent analysis, operations, maintenance, and

decision-making, reduce fault delays, and improve transportation effi ciency.

Maintenance Friendly

The system adopts an integrated design, with the indoor equipment incorporating an analog network, direction switching circuits, analog

signal acquisition circuits, current sensors, and alarm relays. This reduces external cable connections, saves corresponding relays, simplifi es

installation, effectively reduces project costs, and facilitates engineering design, implementation, and maintenance.
