Based on the microcontroller AT89C51, an eight regional wireless burglar alarm system is designed in this paper. This burglar alarm is composed of an infrared sensor chip BISS0001 as a detector, the microcontroller AT89C51 as controller and LX2262/LX2272 as encoder/decoder. Via an external remote controller, it can achieve eight monitored region arming and disarming, and burglar alarming. The design...
The accurate measurement of the fuze action time plays a major role in improving the accuracy of the fuze explosion and the damage effectiveness of the weapon systems. In this paper, an advanced near-infrared detection technology is adopted to detect accurately the fuze action time in order to improve the accuracy of the fuze action time and achieve a distance measurement.
Based on the structural principle of the infrared detection technology and the temperature measure of rotary wheel. First of all, the type of infrared thermometer is selected according to the practical request of low or high temperature measure of rotary wheel disc. And then, the same point temperature of the turbine wheel disc of an engine is measured through infrared thermometer and thermoelectric...
In view of the shortcomings exist in current process of medical transfusion, a wireless distributed system for transfusion supervision was designed with infrared detection technology, computer network technology, embedded system technology and wireless transmission technology. The system is a network which consisted of a host computer, transfusion monitors, and interconnection mechanisms between the...
