Abstract

Automobile, aircraft and other manufacturing industries to promote the rapid development of China's vacuum furnace industry. Low pressure carburizing and high pressure gas quenching technology, such as mechanical equivalent of heat to deal with the main directions of technological development. At present, these technologies have tended to improve and meet the requirements of high-volume production.

1. System Requirements

Electric power control system a high degree of automation requirements of a stable and reliable, the entire system uses real-time operational control of multi-tasking. Automatic control of loading, speed, temperature, carbon potential, can achieve more than group control; through the HMI to monitor and control the operation of the feed batches, and can be completely set up, storage and control of process procedures. Recording equipment can be fully detected by the operation of the process parameters (part number, material, temperature, atmosphere, etc.), and sent to computer processing and storage.

2. System architecture

Controller using soft logic controller Advantech PAC 5510EKW/TP, vertical and horizontal touch screen using the Kunlun HMITECH TPC105TC-h, touch screen PAC via Ethernet communications, through the serial port with the remote central station and other intelligent instrument of communication, TPC own unlimited points MCGS configuration software embedded version, the next bit through the inverter, relays, solenoid valves, such as the composition of the control collection system.

3. Products

Is in line with the IEC61131 standard 5510EKW/TP soft logic controller, it is the rise in recent years, PC-based architecture PLC, IEC61131 Industrial Control as a unified standard has been progressively network programming not only to control highly complex industrial processes can also be control functions and information management functions into one, and industrial control computers, distributed control system, embedded computer, such as further integration, the realization of large-scale comprehensive automation.

TPC105TC-h, is a low-power embedded CPU Intel Celeron at the core (frequency 400MHz) high-performance embedded industrial computer integration. The product design uses a 10.4-inch high-brightness TFT LCD screen (resolution 800 × 600), eight-wire resistive touch screen (resolution 1024 × 1024), but also pre-installed Microsoft operating system embedded real-time multi-tasking WinCE.net ( Chinese version) and MCGS embedded version of the configuration software (running version).

Features TPC105TC-h
• LCD: 10.4 "TFT LCD screen resolution (800 X 600)
• Motherboard CPU: Embedded low-power CPU motherboards, frequency 400MHz
• Memory: 128M
• Storage: 64M Flash Disk (can be expanded to 256M), 20G hard drive or laptop 256M IDE Flash (optional)
• Touch Screen: 8-wire resistive type, resolution: (1024 X 1024)
• Interface: 4 X RS232, 2 X RS485, 1 X LPT, 2X USB, 1 X LAN, 1XPS / 2 Mouse, 1XPS / 2 Keyboard

4. Software Description

Under the main picture shows the run-time interface, through the configuration software to make a friendly user interface, in the main user interface display system in each of the major part of the operation, including the motor from stopping, valve switching, and temperature and so on, right parameters for the system settings through the following button to switch to the curve, reporting, alarm and so on, can learn about the history of curves, showing real-time, historical data, alarm and so on.
