这种设备的zui简单的结构由一台打印机、 -台卡片阅读机及其通信控制处理  机组成。由于通信线路中的信息是以串行方式传输的，设备中的通信控制处理机需要将输入到计算机的信息由并行转变为串行而送入通信线路，并将  通信线路中送来的信息由串行变为并行后输出;此外还需要按规定的通信规程对信息的传输和纠错等处理工作进行监控。  

为实现控制距离远，精度高，必须提高远程设备信息的精度,因存在多个系统之间的通信问题，有时采用人工方式键入远程指示信息，在数据大的  情况下，导致信息键入失误率上升。为提高键入远程设备信息的精度,研究实现 了基于ARM的远程设备信息的自动输入转换系统,远程设备信息通  过RS485协议方式传榆至本系统，系统解析信息协议、 分析数据，并将得到的键盘鼠标数据以PS2键盘协议和串口鼠标协议转发给控制系统。在实际  演练中,远程设备信息自动输入转换系统提高了信息的键入精度，为控制自动化提高了效率。

Remote input devices enable users who are far away from the computer to perform batch input jobs on distant computers.

The simplest structure of this device consists of a printer, a card reader and a communication control processing unit. Because the information in the communication line is transmitted in serial mode, the communication control processor in the equipment needs to convert the information input to the computer from parallel to serial and then send it to the communication line, and convert the information sent in the communication line from serial to parallel and then output it. In addition, it is necessary to monitor the transmission of information and the processing of error correction according to the specified communication procedures.

In order to achieve long control distance and high precision, it is necessary to improve the accuracy of remote device information. Because of the communication problem between multiple systems, sometimes the remote indication information is typed manually. In the case of large data, the error rate of information typing is increased. In order to improve the accuracy of input remote device information, an ARM-based automatic input and conversion system for remote device information is researched and implemented. Remote device information is transmitted to the system through RS485 protocol. The system analyzes the information protocol, analyzes the data, and forwards the obtained keyboard and mouse data to the control system using PS2 keyboard protocol and serial mouse protocol. In practice, the remote equipment information automatic input conversion system improves the accuracy of information input and the efficiency of control automation.
