Diagnosis of Generator Based on Embedded Sensors
1 Supported by the Natural Science Fund Contract No. 69873007. Abstract In the monitoring system of power plant, the method of gathering real time data of sensors is often adopted. It not only increases the communication burden of monitoring system but also results in erroneous transmitting due to worse electromagnetism environment. For overcomring these shortcomings, we adopt a new approach --...
متن کاملUsing embedded sensors for detecting network attacks
Embedded sensors for intrusion detection consist of code added to the operating system and the programs of the hosts where monitoring will take place. The sensors check for specific conditions that indicate an attack is taking place, or an intrusion has occurred. Embedded sensors have advantages over other data collection techniques (usually implemented as separate processes) in terms of reduce...
متن کاملDoing intrusion detection using embedded sensors —
Intrusion detection systems have usually been developed using large host-based components. These components impose an extra load on the system where they run (sometimes even requiring a dedicated system) and are subject to tampering or disabling by an intruder. Additionally, intrusion detection systems have usually obtained information about host behavior through indirect means, such as audit t...
متن کاملCorrosion Monitoring Using Embedded Piezoelectric Sensors
In this research, a new type of corrosion monitoring technique for reinforce concrete was developed. The technique used piezoelectric sensors to detect the ultrasonic signals during corrosion. The mechanism of the method was presented. Experiment was carried out to monitor the corrosion process using piezoelectric sensors. The corrosion was also monitored using stain gauge for comparison.
متن کاملAquatic Debris Detection Using Embedded Camera Sensors
Aquatic debris monitoring is of great importance to human health, aquatic habitats and water transport. In this paper, we first introduce the prototype of an aquatic sensor node equipped with an embedded camera sensor. Based on this sensing platform, we propose a fast and accurate debris detection algorithm. Our method is specifically designed based on compressive sensing theory to give full co...
