【摘要】 温度检测系统已应用于很多的领域,在传统的温度检测系统中,一般选用的是模拟式温度传感器。当系统进行多点温度测量时,所用模拟温度传感器增多,使系统变得复杂。随着传感器技术的发展,出现数字式温度传感器,有效地解决了模拟式温度传感器外围电路复杂及抗干扰能力差的弊病,降低了对系统的要求。本系统采用ATmega128单片机和AD7416数字温度传感器能够快速有效地实现多点温度测量,且系统结构简单,当测控对象越多越显示其优越性。更多还原

【Abstract】 Temperature measuring system is applied to many fields.In traditional temperature measuring system,commonly analog temperature sensor is choosed.When system detects multiplepoint temperature and the number of analog sensor is increased,the system gets complex.As sensor technology develops,digital temperature sensor appears,it availably solves peripheral circuit complexity of anolog temprature sensor and faint anti-jamming,and reduces request for system.The system adopts Atmega128 singling chip microcomputer and AD7416 digital temperature sensor and can availably achieve temperature measuring,furthermore construction of system is simple.When the detected object is more,its advantage can be displayed.更多还原
