The hottest wireless sensor system in Europe to pr

Recently, the European Institute for telecommunications development and strategy in Heidelberg, Germany, completed the research project wsan4cip in the Seventh Research Framework Plan of the European Union, and developed and tested a wireless sensor based power and water supply network monitoring solution

critical infrastructure is facing more and more hacker attacks and other risks. How to reduce these risks and make critical infrastructure more secure is a major social challenge, and a key factor to achieve this goal is the monitoring of infrastructure. The European research project wsan4cip is to achieve a wireless sensor based, cost-effective monitoring solution for power and water supply systems to improve the protection of critical infrastructure. Since February, 2010, the solution has been successfully implemented and tested at the government level in EDP, a Portuguese energy company, and Frankfurt water supply and sewage treatment Co., Ltd. on the Oder River, Germany

in Portugal's power network monitoring, researchers actively monitor multiple safety related parameters through remote control, so as to quickly and reliably obtain information about the power supply network fault and the location where the load value of the measurement and control system should be near zero (without zero adjustment) every time it just enters the experimental interface. Relevant parameters include the condition of the circuit breaker trip coil and the oil temperature of the power transformer, as well as the activities in various stages of the medium and low voltage lines. All monitoring parameters are visualized through a special interface and graphical user interface of SCADA (supervisory control and data acquisition) system

in addition, the system can also detect developing faults by showing the hot spots of medium and low voltage transformers through infrared cameras. If the sensor measures that the technical equipment in the substation has excessive temperature, the alarm will be triggered. If an intruder enters the substation, the camera will also turn on automatically, and the intruder's relevant video and alarm will be sent to the control center

in the application of the Frankfurt water supply system on the Oder River, the wireless sensor and actuator network (WSAN) monitors the physical condition of the infrastructure, including detecting intruders through open connections, and measuring water pressure and flow. When the pressure of water suddenly drops, such as accidental damage of water pipes or malicious b0.25 attack, the alarm data will be immediately forwarded to the control center

in order to improve the robustness and resistance of wireless network sensors and actuators, the wsan4cip project team has specially developed a new and improved transmission protocol. Researchers said that the evidence provided by the project showed that a high level of protection for critical infrastructure can be achieved through a wireless sensor and actuator solution, which is easier, faster and more economical to implement than a wired solution
