基于nRF24L01的远程温度检测系统大学本科方案设计书.docVIP

摘 要 温度检测在日常生活、工作和工程实践中具有重要的应用。随着生活水平的提高和科学技术的进步，无论是工业还是农业或者是日常生活中对温度检测的要求越来越高。不仅要做到低耗，还要求进行一定距离的传输。基于这点我们运用两片主控芯片，一个温度传感器，及数码管显示部分，解决了这个日常生活工作中的问题。出于低功耗本设计我们选择了以低功耗见长的430单片机中的F149系列作为主控芯片，工作场所的温度采集用到了温度采集芯片DS18B20来达到一定的准确度和精确度，最后采用nRF24L01模块对采集到的温度数据进行无线传输，从而打破传统温度操作受到距离限制的缺陷。在经过软硬件测试后，我们基本实现了用温度传感器采集温度，用nRF24L01进行一定距离传输后在接受端的数码管上显示出来的模型。传输距离30m,温度范围达到0至125摄氏度，精度1摄氏度。 关键词: msp430f149；nRF24L01；温度；无线传输 ABSTRACT Temperature measurement have important applications in daily life,work and engineering practice.With the improvement of living standards and technological progress，whether industry，agriculture or daily life become increasingly demanding of temperature detection. Not only to achieve low power consumption,but also requires a certain distance transmission. For this reason we solved the problem of daily life and work using two control chips, a temperature sensor, and the led display part. For low-power design we have chosen the low-power microcontroller known for the F149 series of 430 as the master chip, temperature acquisition DS18B20 has used to achieve a certain accuracy and precision, Finally nRF24L01 module temperature data collected by wireless transmission, thus breaking the distance limitations of traditional temperature operation. After software and hardware testing, we basically realize our Initial target. Transmission distance30m, temperature range 0 to 125 degrees, 1 degree accuracy.
