But the traditional recorder has a lot of shortages ; complicated structure , simple function , frequently addinq ink and paper changed etc . in addition , the data are registered in paper with the shape of a curve , so it is not convenient to saving , processing and editing of a file . the paperless recording instrument will initiated an epoch , because it has integrated the electronic technology , cyber - technique and network communication technology 传统的模拟记录仪结构复杂，功能单一，必须换纸，加墨水，数据总是以曲线的形式存在于纸上，对历史数据的保存方式单一，对数据的处理，编辑等都存在不足，而集微电子技术，计算机技术，网络通讯技术为一体的无纸记录仪开创了记录仪表的新纪元。
It is very important to develop the paperless recording instrument ( dr1000 ) . the study are based on the concept of intellectualized instrument , and i have adopted the method of low - cost automatic system . in the hardware , bring up an embedded system of single chip based on cpu ( 80c ! 96kc ) ; in the software , i used series 96 compile language and visual program based on vb in recording instrument 本课题提出开发的无纸记录仪是从智能仪器仪表开发的概念出发，采用低成本的自动化小系统的研究方法，提出了一种在硬件上基于以80c196kc为微处理器的单片机控制的小嵌入式系统，在下位机软件基于96系列的通用汇编语言，而上位机基于vb的可视化编程。
The voice recording instrument adopts 8bit pcm and 4bit adpcm voice coding and decoding mode , can record the eight - channel voice signal simultaneously . it can save the recorded data in the flash memory or in the pc through the ethernet . the recorded voice signal data also can be played back 该语音记录仪采用8位pcm或4位adpcm语音编解码方式工作,可实现8路音频输入信号同时录音;能够将录制的数字语音数据存储在nand型flash中或通过以太网接口上传到pc机存储;能够将录制的数字语音数据进行回放。
