Abstract: Aimed at the defects of security monitoring system in intelligent building with complicated design, higher production cost, uneasy to installation, and not suitable for ordinary family, this paper combined with the development needs of intelligent building, and designed a remote network security monitoring system based on Internet, used AT91SAM9260 as the main controller and used embedded technology, Internet technology, video compression/decompression technology and so on. So that users can detect the illegal intrusion and fire hazards at home in real-time, through computers or mobile phones. Then the validity and efficiency of the system was validated via test-experiment. The results show that this system has several merits such as good safety, good generality, simple operation, easy maintenance, low cost and so on. It can meet the needs of security monitoring for an ordinary home.

Abstract: Water quality monitoring plays an important role in contamination control and environment protection. This paper describes an on-line multiparametric water quality monitoring system based on visible spectrophotometry, which combines embedded technology with GPRS telecommunication technology. This system can realize online wireless monitoring to concentrations of chromium (Cr), plumbum (Pb), A surfactant (AS), chemical oxygen demand (COD), ammonia nitrogen (AN), total phosphorus (TP) and total phenol (TPh) in real time. The mechanical structure, hardware circuit and software design of the system are completed. The absorption spectrums of pure water and MB-SDS complex have been measured. Preliminary experiments using a model machine show that each mechanism of the system runs well. Moreover, the monitor possesses many advantages, such as high degree of automation, high reliability, high efficiency, compact structure, small size, and so on.

Abstract: Ultrasonic effect is widely applied in biomaterial treatment and this process will happen in ultrasonic reaction kettle of which physical parameters directly affect the treatment effect. This paper introduces a kind of monitored control system of ultrasonic reaction kettle and mainly presents the realization method of key units. Depending on embedded technology, this system includes three layers control unit: ARM central control layer, PC control layer and bottom CAN intelligent node layer which has sensors and actuators. Linux operating system has been transplanted on ARM processor as the software platform. Through the practical hardware arrangement and software design, it can be proved that this system can effectively and accurately monitored control the parameters of ultrasonic reaction kettle.
