Introduces a kind of carbon monoxide alarm apparatus that combines together the design with MSP430F149 MCU and the electrochemistry sensor. Take advantage of the MCU′s ultra-low-power and high-integration,and also the electrochemistry sensor′s high-selectivity and the high-accuracy.
It's hardware consists of five parts,namely,a sensor master tester,display,print and an alarm unit,because the sensor which is masked by metal film uses modulating and inducing technology,its zero offset is reduced,its ability of an interference is raised,the design realized the high reliability,stability and high cost performance of the system.
Large amounts of data in the SCADA systems' databases of thermal power plants have been used for monitoring, control and over-limit alarm, but not for fault diagnosis.
The mechanisms of generating alarm calls of different bird species, species-specific calls of closely related species, and intraspecific differences in calls were analyzed.
The hypothesis of "autoimmune testing" of mating partners assumes the formation of an immune-based individual perception system involving intravital selection of direct or inverse replica of self key antigens or alarm molecules.
A relationship was established between the amplitude modulation and the structure of call spectrum in animals by the example of alarm call in three marmots (Marmota sibirica, M.
The keeping of rats in crowding conditions induced chronic stress, which developed, according to phase changes in plasma concentration of corticosterone and adrenal content of cholesterol, through the stages alarm, resistance, and exhaustion.
