Invasion detection systems are mostly based on a single type of sensor system. In this system, we use sensors to monitor a variety of targets, and miscarriage of justice or missing issue often happens. Therefore we upgrade the intrusion detection system to multi- types of sensor based systems. How can a variety of sensors collect

Oil pollution levels can quantitatively reflect the degree of oil pollution and it is an important theoretical basis of oil pollution control. According to statistics, 70%-85% failure of the hydraulic system is caused by oil pollution. Therefore, the detection of oil pollution level has great significance in improving the reliability and extending the service life
