Development of single bus medical temperature measure system / 医疗卫生装备

ABSTRACT

This design is a multi-point thermometry system based on single bus digital thermometer DS1820.The single bus system of multi-point measure temperature is developed with single chip computer 89C52 and circuit units for physiological signal measurement.Obtainment method of higher resolution temperature data is given.The method makes measure temperature resolution reach to 0.1?C.It is characterized by simplicity of structure,high precision and real time,and is easy to transmit by internet network.So the system has widely applications value on clinic.
