In the emergency warning system of a tunnel, we need to control the cameras and to receive signals from smoke sensors and transmitters. We can build an immediate and control system through the internet with ICP DAS ET-7000 series. They can be linked to devices like cameras, smoke sensors and transmitters. They can send digital output signals to devices like web based LED displays. These displays can help warn drivers about obstructions to keep the roadway smooth and safe. The ICP DAS ET-7000 series have built in web servers, web HMI, dual watchdog, I/O pair connection and support Modbus/TCP protocol.
