The development of an intelligent small Paperless recorder

    Summary: Inherited from the successful design of the large Paperless recorder, the intelligent small Paperless recorder has a modular structure. It also employs the same data acquisition module as the large Paperless recorder does. It has a menu driven GUI (full Chinese language), eight multi-purpose input channels (all user configurable), 16-channel relay outputs and 2-channel analog outputs (V/mA). Though a MCS51 based MCU is used as the main controller, the limitations of 64K RAM and ROM of this kind of MCU have been conquered through page mapping and code banking technologies. The paper describes how to accomplish this breakthrough from the aspects of hardware and software design.

The development of an intelligent small paperless recorder

    This is a paperless recorder that displays measured data on the LCD in real time and stores data in Compact Flash Paperless recorder . The type of input such as thermocouple, resistance bulb, D.C. voltage (current), etc. can be arbitrarily set to 18 channels at the maximum.The data stored in CompactFlash can be regenerated on the screen, and the use of supplied support software allows the data to be regenerated on a PC screen.The data recorded in ASCII format can be directly read in a spreadsheet such as Excel, which facilitates the processing on a PC. (The data recorded in binary format cannot be read in Features.

    1.Large capacity storage by CompactFlash Measured data is periodically stored in CompactFlash.

    Paperless recorderLarge storage capacity of up to 256MB allows display files for approximately one and a half years to be recorded continuously at the display refresh cycle of 30 seconds Paperless recorder .

    2.Quick search and display of past data, Data stored in CompactFlash can be displayed in succession by scrolling the screen.

    3.Various display capability Depending on the object of measurement, the most suitable display format can be selected from a variety of formats including bar graph display, trend display, digital display, etc.

    4.PC support software supplied as standard Loader Paperless recorder software that enables easy display and change of set data and data viewer software that regenerates the data stored in CompactFlash are supplied as standard.

    5.18-point recording (Option) 12 types of thermocouples, Paperless recorder 2 types of resistance bulbs and DC voltage/current input can be recorded up to 18 points.
