基于ATMega168的电热器具测试模块

Test Module of Heating Appliance Based on ATMega168

本文介绍的测试模块采用Atmega168单片机作为核心控制器,BC7281B键盘控制器作为测试范围输入设备和显示设备。AVR单片机扫描键盘并且读入用户设定的范围值并将其显示,设定完毕后,连接好待测品,检测系统自动进入测试状态,第一阶段测试完毕后,AVR单片机指示检测人员进入第二阶段测试,测试完毕判断被测品是否合格。实际应用表明该测控系统具有测量精度高,可靠性高的特点。

This paper introduces the test module which adopted Atmega168 as the core controller, keyboard controller BC7281B as the test input and display devices. AVR single-chip computer scanning the keyboard to read the input and the test range and displays them. When finished settings, connecting the product to the power, the module will start test procedure automatically. After finishing the first test step the module indicates to inform the tester to start the second step. After finished all the test step the test module gives the result to the tester whether the product is qualified or not. The practical application shows that the measurement and control system has high measurement precision and high reliability.
