摘要
用于测试的多功能检测仪采用MCS51单片机进行测试控制,实现信号采集、存储和信息显示。该仪器采用CPLD扩展外围接口,简化了硬件电路的设计;采用MAX392多路选择器实现了多路选通。检测仪具有的推土/绞盘等按钮,在控制盒失效时可作为代用按钮使用。该仪器软件部分采用模块化的设计思想,为以后的升级、维护提供了方便。
The muitifunctional detecting instrument adopts the MCS51 monolithic machine to carry out the testing and control, realizes the signal collection,memory and visualization. The instrument adopts CPLD to expand external interface,which simplify the circuit design of hardware;adopts the multi-path selector of MAX392 to realize multi-path selection. The instrument also has buttons such as the soil/capstan, which will be used as substitutes when the controlling box is invalid. The software of this instrument adopts modularized design method ,for the convenience of promotion and upkeep in the hereafter.
