Because there are a large number of power distribution transformer stations and they are far away from city, wireless GPRS transmission provides a good communication solution to supervise power distribution transformer stations. The scheme of remote wireless monitoring system for power distribution transformer station based on GPRS wireless network was designed in this paper. A control terminal system...
One of the difficult problems in dairy farming is detection of cows' estrus, whose technology has been developed in some countries; however it is still in the developing stage in China. This paper presents a new method which resorts to collecting cattle's body temperature and behavior characteristics for detecting the cow's estrus. According to the body temperature of dairy cattle rising 1-2° in ovulation...
ZigBee wireless sensor network usually works in a complex environment, and the energy of sensor node is very limited, so energy consumption is a big problem in ZigBee wireless sensor network,especially in the multi-sensor system. Plant eco-physiological monitoring system is a typical multi-sensor system. There are many kinds of sensors in this system. These sensors, as well as ZigBee module and some...
Literatures in the health areas are reported frequently on accidents caused by problems with shock during surgery in both patients as the clinical team. It should be noted that most electrical equipment, during use, is often in contact with the patient and / or with medical professionals. Therefore, the electric shock danger always exists in this environment. To avoid this, some equipment has been...
