本文中数字电压表的控制系统采用AT89C51单片机,A/D转换器采用ADC0809为主要硬件,实现数字电压表的硬件电路与软件设计。该系统的数字电压表电路简单,所用的元件较少,成本低,调节工作可实现自动化。还可以方便地进行8路A/D转换量的测量,远程测量结果传送等功能。数字电压表可以测量0~5V的8路输入电压值,并在四位LED数码管上轮流显示或单路选择显示。-IMDN开发者社群-imdn.cn"> 本文中数字电压表的控制系统采用AT89C51单片机,A/D转换器采用ADC0809为主要硬件,实现数字电压表的硬件电路与软件设计。该系统的数字电压表电路简单,所用的元件较少,成本低,调节工作可实现自动化。还可以方便地进行8路A/D转换量的测量,远程测量结果传送等功能。数字电压表可以测量0~5V的8路输入电压值,并在四位LED数码管上轮流显示或单路选择显示。 - IMDN开发者社群-imdn.cn">

    设为停车场内只有一个可停放n辆汽车的狭长通道,且只有一个大门可供汽车进出,汽车在停车场内按车辆到达时间的先后顺序,依此由北向南排列(大门在最南端,最初到达的汽车停放在停车场的最北端),若停车场内已停满了n辆汽车,则后来的汽车只能在门外的便道上等候,一旦有汽车开走,在它之后开入的车辆必须先退出停车场为它让路,待该辆开出大门外,其它车辆再按原次序进入停车场,每辆停放在停车场在汽车在它离开停车场时必须按它停留时间-Set only a car park to park cars n the narrow channel and only one door and out of cars, cars in the carpark by the arrival of the vehicles in chronological order, and so north to south with (the southernmost tip of the door, first arrived in a car parked in the parking lot of the most North) if parking has been full of parked cars in the n, the car was only at the door waiting on the sidewalk, when the bus pulled away, after it was opened to vehicles must first withdraw from the car park to make way for it, when the big vehicles out the door, other vehicles according to the original order of entry, in each park parking in the car when it left the car park as it must stay

    说明:  为解决实际测控系统中在控制中心的上位机和控制功能设备的下位机之间传送命令和文件的问题,在讨论VC++6.0中MSComm控件的基础上,通过制定通信协议、给命令和文件加入标识构成包进行传送,从而正确地区分了命令和文件.实验表明,基于该通信协议,可以成功地传送命令和多类型文件. (To address the actual measurement and control system in the Control Center PC and control functions of equipment under the digital transmission between orders and documents, in discussing the VC++ 6.0 in MSComm control on the basis of the communication protocol through the development to the orders and adding logo files constitute a packet transmitted, thereby correct distinction between the orders and documents. The experimental results show that based on the communication protocol, you can successfully send a command and multi-type documents.)
