Control Room
Control Room is a large scale multimedia installation located in the reception area of Museum of City Infrastructure. It is a single information module composed of a HDR COB LED screen (12.5 x 5 m) and 18 touch-screen panels. The main screen consists of 294 LED cabinets and displays real-time information about the tasks and operations of the municipal services. The video signal source (total resolution of 7,872 x 3,240 px) is a ScreenBerry 2.0 media server.
Control Room visualization, view from museum entry point
The bottom row consists of 18 touch-sensitive 55" interactive panels. It enables visitor’s interaction with the museum navigation app. The GUI is an HTML5 application running on a fanless embedded computer. Each of the 18 screens can be operated simultaneously to form a seamless interactive canvas. It is possible to switch the main screen of the Control Room to presentation mode. Screen sharing is available from any computer connected to the museum's Wi-Fi network.

Full set of the documentation was developed before production and site installation phase.
Fragments of project technical documentation
One of the main challenges was to ensure power and safe start-up of the installation without overloading the building's power supply systems. The inrush current for LED cabinet power supply can be up to 120A during a cold start. In order to reduce the total inrush current, a sequential (time-differentiated) start-up of the LED screen supply groups is used. Since the main inrush current during a power supply cold start is generated by the discharged capacitor, ABB UA16-30-10RA capacitive load contactors equipped with additional resistors are used to reduce the inrush current. Each three-phase supply group is equipped with a residual-current circuit breaker and an automatic circuit breaker. The power groups are started sequentially, with a 0.5 sec delay. The start-up routine is controlled by a Programmable Logic Controller (PLC) – Siemens Simatic CPU1214C. The protection devices of each power group are equipped with a block contact for diagnosing and alarm handling.
Main control cabinet
The installation controller is connected as a client to the museum's system of control and monitoring (SUMO). In case of an abnormal situation, the technicians will be notified that the power supply system protection devices have been triggered. Thanks to SUMO, museum staff have the opportunity to switch installation operation modes manually as well as to program automatic scheduled operation.
Multimedia rack and 18 fanless PCs on the backplanes
Operation is controlled via interface on the museum administrator's tablet (Apple iPad). MQTT implemented on a Siemens PLC is used as a universal transport protocol.
Installation in progress
PITCH team carried out field supervision, installation and commissioning of this installation in the fall of 2021.
