Road Machinery
General view of the installation
A kinetic installation Road Machinery presents a two-axis mobile panel computer that can be moved by a visitor along high relief models of municipal road machinery. By placing the screen in front of a particular vehicle model, the visitor can examine its 3D model in detail, take a look at additional photos (including historical ones), learn about its functions and design, discover some interesting facts, e.g., how a particular car has been depicted in popular culture.
Concept visualizations
PITCH Engineering Department has carried out the complete cycle of the installation elaboration, including selection of components, constructive and engineering solutions, detailed project documentation development, production/manufacture control, assembling, commissioning and programming.
3D CAD model
The Bosch Rexroth cam roller guides are used as a linear motion solution. Comfortable vertical movement and fixation in front of a selected model is provided by a counterweight.
Fragments of project documentation
The screen is an industrial fanless panel computer with a 21.5" IPS matrix. The computer runs a Unity app which displays a 3D model depending on the position of the screen. The position is determined by two absolute optical wire draw encoders.
Assembly and commissioning moments
The installation control system is based on a Siemens Simatic PLC. The PLC converts the data received from the encoder via PROFINET. Real-time data exchange between the PLC and the panel computer is performed via the PUP9000 (Pitch Universal Protocol) developed by engineering department.
Complete installation in the museum
The operation of the installation is fully automated due to integration with the museum's system of control and monitoring (SUMO). The installation works in fully automatic mode, switching on and off according to a schedule. MQTT with a Siemens PLC based client implementation is used as a universal transport protocol for data exchange between the installation and the central control system.
