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.
This is a
Paperless recorder that displays measured data on the LCD in real time and stores data in Compact FlashPaperless 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
