Elevator
Installation overall view in the museum
"Elevator" multimedia installation is a single information module with an integrated cabin and automatic doors. The combination of the original elevator equipment and upper screens creates an image of a transparent elevator shaft through which a virtual lift is moving. Museum visitors can routinely call the elevator by pressing a button. As the virtual elevator arrives, the doors open and a built-in screen demonstrates a perspective extension and details about design and engineering features of this model. The upper screen is an HDR COB front-mounted display of 1824x3078 mm with a pixel pitch of 1.56 mm. The cabin screen is also an HDR COB display with 0.9 mm pixel and a resolution of 1280x2520 px. The total height of the structure is 6 metres.
Installation concept visualization
PITCH Engineering Department has carried out the complete cycle of engineering, including the structural design, integration of a real series-produced elevator cabin, development of multimedia equipment, system of automatic control, soft-start, monitoring and power control for LED screens.
3D CAD model
The source of audio and video content is the ScreenBerry 2.0 media server. Video signal is converted by the Novostar LED screen controller. The installation sound setup includes Seeburg L16i loudspeakers for main sound and Genelec 4020C for rear fill inside the elevator cabin.
Fragments of technical documentation
Control of the installation operation scenario, content playback, automatic cabin doors and soft-start of the LED screens is carried out by a Siemens Simatic S7-1212C programmable logic controller. Real-time data exchange between the PLC and the media server is performed via the PUP9000 (Pitch Universal Protocol) in-house developed protocol.

Electrical cabinet with soft-start contactors
High density of the construction arrangement as well as relatively high installation complexity required to develop a number of out-of-the-box solutions, among them – separation of control system cabinets into a power supply and soft-start cabinet, a control cabinet and a compact multimedia rack. The requirement to maintain the screen integrated into the elevator cabin from the front demanded the development of a hinged flush-frame unit that pushes the screen inside the installation’s body.
Assembly works moments
The operations of the installation are fully automated by means of integration with the museum's system of control and monitoring (SUMO). The installation operates in fully automatic mode, switching on and off according to a schedule. It is possible to control the installation manually and to put it into a service mode for maintenance purposes. MQTT is used as a universal transport protocol for communication between the installation and the central control system, with a Siemens PLC client implementation.
