Diagram of the Gas Supply System
Overall view in the museum
The installation presents an interactive diagram of the gas supply system of a city. It is designed to demonstrate how the gas supply is shut off and rerouted in case an incident occurs. For this purpose the installation includes a pipeline section with a real shut-off device. The visitor can press the red button to simulate an incident on the gas supply line. The buzzer sounds and the emergency section of the gas line is illuminated in red. The emergency section of the gas line can be shut off either manually by turning the handwheel of the shut-off device, or remotely by pressing the green button which activates real actuator produced by AUMA Riester. Visitors see how the gas supply was re-routed: newly activated sections that were previously in reserve are now highlighted in green and a city district experiences no problems caused by gas supply disruptions.
Concept visualizations
PITCH Engineering Department has developed the structural design of the installation, selection of the shut-off valve and the electric drive, engineering and development of the control system.

Fragments of technical documentation
Control system is developed on the base of Siemens Simatic S7-1212C PLC. The controller implements the game algorithm, actuator control & protection (limit switches and thermal protection), multimedia control (dynamic light and audio signals). A custom microcontroller device has been developed specially to control the addressable LED strip.
Commissioning moments
The installation is fully integrated into the multimedia exposition as it is connected to the museum's system of control and monitoring (SUMO). The exhibit runs fully automatically according to a schedule and reports all abnormal situations or errors. MQTT implemented on a Siemens Simatic PLC is used as a universal transport protocol to exchange data between the installation and the central control system.
