摘要
给出了基于ATmega162单片机的某军用传感器网络远程终端数据采集器设计,设计采用MAX232电平转换电路实现了ATmega162与MODEM,及ATmega162与串口的数据通信,通过液晶显示与按键实现人机交互控制,采用MODEM对传感器数据进行调制变换,并将变换后的模拟信号通过双绞线发送到远程数据终端。系统安全可靠,能够较好完成远程数据传感器的数据采集与远程传输功能,通过系统测试验证该采集系统能够顺利完成对多种传感器数据的采集与传输,能够满足远程传输网络对数据传输的要求。
The paper presents a remote data acquisition system for military sensor network based on Atmega162,it makes use of MAX232 to fulfill the communication between ATmega162 and modem,and ATmega162 and series interface.The operator can chose work mode by controling LCD screen and key.Datum are modulated in modem which are sent to remote data terminal after transfoming to analog signals.All in all system is security and credity which can implement the function of data acquisition and remote communication.
