摘要
针对一些重要参数远距离监测的需要,设计了以AVR单片机为控制核心,以被测环境的温度为遥测对象的实用数字遥测系统。主要阐述了系统的设计思想和工作原理,详细介绍了系统硬件设计、软件工作流程及测试结果。该系统采用AD590温度传感器与ATmega16型AVR单片机实现对环境温度的监测,通过无线通信模块SRWF-508进行远距离信息传输。系统简单实用,测量精度高。同时出于对功能扩展的考虑,系统采用了标准化模块设计。只需更换不同的传感器,即可完成对频率、压力、湿度等其他参数的遥测。
Based on the demand of monitoring some important parameters of long-distance,a digital temperature telemetry system is designed in this paper,in which the AVR MCU works as a core-controller and the environmental temperature is the detected object.The design idea and operation principle of the system are introduced mainly in the paper.And the realization of hardware,the design of software flowchart and the testing consequence are explained in detail.The system adopts Atmega16 AVR MCU and AD590 temperature sensor to achieve temperature measuring,and the wireless communication module SRWF-508 is adopted to transmit information in the distance.The system has many advantages such as simple structure,higher measurement accuracy and reliability.Considering expanding it,standardize module design is adopted in the system.If different sensors is replaced,it can also detect other parameters like frequency,pressure,humidity and so on.
