What is ASOZ?

Automated Depot Service System

The ASOZ system is designed to support modern streetcar, rail and trolleybus depots. The main task of the system is the automated management of vehicle traffic at the depot with a high level of safety.

The system includes: Depot Management System (IT system), Traffic Control System (industrial automation), and control and detection elements installed in the tracks and vehicles.

How does ASOZ work?

Automatic motion cont

RFID tags installed in vehicles allow automatic recognition of units of rolling stock entering the depot. The identified vehicle is directed by the system to the appropriate parking place, determined taking into account the current timetable and the transport tasks to be carried out.

The Operator’s terminal shows the locations of all vehicles on the depot premises, the routes determined by the Depot Management System and messages from measuring devices. The ASOZ system also allows the operation of vehicles not equipped with RFID tags. After the operator enters information about the vehicle’s side number at the entrance to the depot, the system controls the vehicle’s passage to the designated parking space and allows the vehicle’s location to be tracked on the depot diagram.

The system is integrated with a station for detecting the classification of flat spots and wheel stickers, as well as a laser wheel measuring station.


Why choose the ASOZ system?

Increased safety levels

Easy integration with devices and external IT systems

Easy and centralized management of inspections

Comprehensive planning of vehicle servicing and maintenance tasks

Functionality of the ASOZ system

Comprehensive Support

The Traffic Control System is responsible for the safety of tram traffic within the Depot. It covers the entire track infrastructure responsible for the safe movement of vehicles within the depot, including switch control, signal control, detection and safety elements, and ensuring safety requirements in SIL3 class. The system automatically responds to various emergency and atypical situations, recording infrastructure failures and presenting their locations on the Operator’s Terminal.

The system is equipped with various reports, allowing the Operator to summarize information collected during the system’s operation. The reports provide information on service dispatches, cyclical events, vehicle departure times, tram driver working times, infrastructure failures, and all routes completed within the depot area.

The system automatically assigns parking spaces within the depot, taking into account:

  • Type of fleet
  • Available parking spaces
  • Service and repair activities
  • Additional carrier rules (e.g., consideration of agreements with advertisers, additional orders for passenger transport)
The functionality operates, taking into account:

  • Control of vehicles without RFID markers
  • Handling the simultaneous movement of multiple vehicles within the depot
  • Indicating the track number to the approaching driver entering the depot

It provides information such as:

  • location of all vehicles within the depot
  • routes designated by the Depot Management System
  • messages from devices located within the depot
The Driver’s Terminal is located in the dispatch room. Before starting the route, the driver checks information about the assigned line, brigade, as well as the side number of the vehicle and the parking track where the vehicle is parked.
This functionality is performed by logging the motorman into the onboard computer in the vehicle.
The functionality of recording service orders using the Master Terminal based on information about vehicle breakdowns. Failures can be reported automatically by appropriate diagnostic devices or entered manually based on reports from the motorman.
A series of reports allowing the Operator to summarize information collected while working with the System in a consistent and clear manner. The reports provide information on service orders, both ad-hoc and cyclical, created for all vehicles, departure times for all vehicles, motorman working hours, infrastructure failures, vehicle repairs, and all routes completed on the depot premises.

As part of the implementation, elements of infrastructure and systems supporting depot operations may also be designed and delivered, such as fiber optic networks, industrial CCTV, DECT telephony, access control, Automatic Fire Detection System (SAP), intrusion and hold-up alarm system (SSWiN), and building automation system (BMS).

All of the above elements contribute to improving safety, functionality, and work comfort in a depot served by the ASOZ system.
