Color paperless recorder

Color Paperless Recorder for Enhanced Industrial Monitoring

The color paperless graphic recorder is a next-generation recording instrument that integrates multiple microprocessors, providing robust network capabilities and real-time performance. Its universal input supports standard voltage, current, thermal resistance, and thermocouple signals, which simplifies installation and adjustment. Advanced A/D conversion and self-correction technology enhance the recorder’s resilience to temperature and time drift while filtering out interference in challenging environments. The large-capacity RAM (1M) with power-off protection, coupled with a CF memory card (128M–1G), resolves the issue between immediate data review and long-term storage needs.

Equipped with a TFT true-color 5-inch LCD screen, the color electronic recorder expands display options. Its user-friendly interface includes multiple screens, such as engineering display, bar graph, and curve display for easy referencing. System settings can be navigated through flexible English menus and are password-protected. Additionally, chino paperless recorder features an RS-232/RS-485 communication interface, allowing for data exchange and remote configuration with a PC, as well as connection to an external micro-serial printer for data and alarm status printing. Constructed with a special aluminum alloy shell, paperless data recorder offers superior anti-interference capabilities, easy installation, and a practical, attractive design. This digital paperless recorder is ideal for industries like chemical processing, metallurgy, and petroleum, providing data sampling, monitoring, analysis, and storage to overcome limitations of traditional mechanical paper recorders.

Working Principle of the Color Paperless Recorder

The color paperless recorder’s channel board samples each analog input, amplifies the signal, and processes it through an A/D converter to convert it into a digital signal. This data is then filtered and stored in the data storage area. The channel board CPU communicates with the main board CPU every 0.2 seconds, transmitting data that is processed, converted into engineering values or curves, and displayed in various screens on the LCD. The CPU stores this data in both RAM and the FLASH memory card and manages alarm settings, displaying alarms via corresponding relay outputs. User commands from the keyboard are processed through the CPU, and data is printed through the RS-232 interface as per the user’s print settings.

Hardware Structure of the Color Paperless Recorder

The color paperless chart recorder comprises the following components: main board, channel board, display screen, keyboard, memory card, relay output board, communication board, and power supply. These elements are interconnected by ribbon cables and bus slots for seamless operation.

Display Screen

The dot-matrix color LCD screen (resolution: 220×160) displays up to 8 colors, supporting Chinese character display, graphics, and tables.

Main Board

The main board features an 8-bit microcontroller system with components such as CPU (80C31, 80C32), EPROM, EEPROM, RAM, watchdog, and clock, which collectively manage the input signal processing, alarm outputs, and communication. Data and settings are safeguarded through RAM with power-off protection and the EEPROM.

Relay Control Unit

This unit provides control signals for relay on/off states based on the alarm output status.

Channel Board

This board processes various analog signals from thermocouples and thermal resistors, amplifies signals, performs A/D conversions, and stores the average value of converted data.

Power Supply Circuit

The low-voltage switching power supply improves efficiency, with options for AC 220V or DC 24V input to suit different industrial environments.

Host Shell

A specially designed aluminum alloy profile with an opening size of 138 mm × 138 mm provides anti-interference features and an aesthetically pleasing appearance.

Key Technologies of the Color Paperless Recorder

Universal Signal Input

With rear terminal wiring, DIP switch settings, and system menu adjustments, the recorder supports universal input of various signal types, making it highly adaptable.

Thermal Resistor Sampling

The color paperless recorder uses an analog switch for thermal resistor signal sampling. Voltage readings are taken from the Y-end, allowing for accurate resistance measurements and improved precision.
