ABB 216VC62a 模拟输入板

输入设备是向计算机输入数据和信息的设备，是计算机与用户或其他设备通信的桥梁，用户和计算机系统之间进行信息交换的主要装置之一。 输入设备的任务是把数据、指令及某些标志信息等输送到计算机中去。键盘、鼠标、摄像头、扫描仪、光笔、写输入板、游戏杆、语音输入装置等都属于输入设备(Input Device )，是 人或外部与计算机进行交互的一种装置,用于把原始数据和处理这些数据的程序输入到计算机中。计算机能够接收各种各样的数据，既可以是数值型的数据，也可以是各种非数值型的数据，如图形、图像、声音等都可以通过不同类型的输入设备输

入到计算机中，进行存储、处理和输出。计算机的[1 ]输入设备按功能可分为下列几类:

●字符输入设备:键盘;

●光学阅读设备:光学标记阅读机、光学字符阅读机;

●图形输入设备:鼠标器、操纵杆、光笔;

●图像输入设备:数码像机、扫描仪、传真机;

●模拟输入设备:语言模数转换识别系统。

(如光电纸带输入器、卡片输入器、光学字符读出器、磁带输入装备、汉字输入装备、鼠标等)将数据、程序和控制信息送入计算机内。

Input devices are devices that input data and information to computers, serving as a bridge for communication between computers and users or other devices. They are one of the main devices for information exchange between users and computer systems. The task of the input device is to transmit data, instructions, and certain flag information to the computer. Keyboard, mouse, camera, scanner, light pen, writing input board, joystick, voice input device, etc. are all input devices, which are devices used for human or external interaction with the computer to input raw data and programs for processing these data into the computer. Computers can receive various types of data, whether numerical or non numerical, such as graphics, images, sound, etc., which can be input through different types of input devices

Enter the computer for storage, processing, and output. The input devices of computers can be divided into the following categories according to their functions:

Character input device: keyboard;

● Optical reading equipment: optical marker readers, optical character readers;

● Graphics input devices: mouse, joystick, light pen;

● Image input devices: digital cameras, scanners, fax machines;

● Analog input device: language analog-to-digital conversion recognition system.

(such as photoelectric paper tape input device, card input device, optical character reader, magnetic tape input device, Chinese character input device, mouse, etc.) Send data, programs, and control information into the computer.
