Common paperless recorder configuration methods
2011-8-27 9:31:38

现代化工业控制领域和新技术领域的 迅猛 发展, 工业生产和科学研究的各个部门 以工业微处理器CPU 为核心的新型显示记录仪表已被越来越广泛地应用 Due to the rapid development of the modern industrial control field and new technology field , in various departments of industrial production and scientific research , new display recording instruments with industrial microprocessor CPU as the core have been more and more widely used . 无纸记录仪 ,这种记录仪 完全摒弃传统记录仪的机械传动,纸张和笔, 采用 CPU 为核心 采用液晶显示的记录仪 After the 1990s , various industrial automation instrument manufacturers began to develop and launch new display recording instruments-pen- free and paper-less recorders . This recorder completely abandons the mechanical drive of traditional recorders, paper and pen, and uses the CPU as the Core , recorder with LCD display . 直接把记录信号转化成数字信号后,送到随机 存储器 加以保存, 还可以 在大屏液晶显示屏上加以显示。 This paperless recorder can directly convert the recorded signal into a digital signal and send it to a random memory for storage. It can also be displayed on a large-screen LCD screen. 记录信号是由工业 专用 微型处理器CPU 来进行转化 保存 显示的, 所以 记录信号可以随意放大 缩小地在显示屏上显示,极大的方便 观察记录信号状态。 Because the recording signal is converted , saved , and displayed by a dedicated microprocessor processor in the industry , the recorded signal can be displayed on the display screen as it is enlarged or reduced, which greatly facilitates the observation of the state of the recorded signal. 必要 把记录曲线或 数据送 打印机或 个人计算机加以保存和进一步处理。 When necessary , the recorded curve or data can be sent to a printer or personal computer for storage and further processing. 可以 多样化, 可与热电偶 热电阻 辐射感温器或 其他产生直流电压 直流电流 频率等变送器配合使用 ;还可以 数字显示温度 压力 流量 液位等工艺参数,数字记录 报警 控制对输入信号可以进行组态或 编程直观地显示当前测量值。 The input signal of the instrument can be diversified. It can be used with thermocouples , thermal resistors , radiation temperature sensors or other transmitters that generate DC voltage , DC current , frequency, etc .; it can also display temperature , pressure , flow , and liquid level Such as process parameters, digital recording , alarming , and control of input signals can be configured or programmed to display the current measured value intuitively.

组态方式主要有以下 种: There are six main ways to configure the paperless recorder :
( 1 ) Time and channel configuration. 修改日期,时钟,记录点数和采样周期。 Used to configure or modify the date, clock, number of recording points and sampling period. 量程上下限 报警上下限 滤波时间常数,以及开方与否的设置。 Input signal mode , upper and lower limits of the range, upper and lower limits of the alarm , filter time constant, and the setting of the square root or not.
( 2 ) Configuration of page and record interval. For the flow signal, it can be used for square root, flow accumulation and flow temperature and pressure compensation.
  3 )显示画面选择组态。 ( 3 ) Display configuration selection. 画面或 更多画面的显示。 The paperless recorder can display nine or more screens. Through configuration, you can select the screen that needs to be displayed most.

  ( 4 ) Configuration of communication information. It is used to set the communication address and communication method of the microcomputer.
5 )可通过组态选择合适的工程单位。 ( 5 ) The appropriate engineering unit can be selected through configuration. If it has a PID control module, it can realize a PID control loop.  

  ( 6 ) Configuration of alarm information. 上限 下下限和下限报警触点的设置。 Setting of upper , upper , lower, and lower alarm contacts for each channel .
