RESUMEN
Objective In order to carry out the research of the non-invasive core temperature measurement,the paper designs a portable sixteen channels temperature measurement system. Method Using MCU MSP430F149,this paper applies the technology of analog signal acquisition and digital signal process to establish a multi-channel temperature system. Result The system can store and send the temperature signals through wire and wireless communication mode. Conclusion The system is stable and reliable,and the precision of the system satisfies the clinical demand.
RESUMEN
When semiconductor chilling plate is used in parallel connection mode,a DC power supply with a low voltage and high current has to be available.A power supply of 1.8V,14A is designed to meet above demand.
