Railway signal microcomputer monitoring system
System requirements: 4U highly industrial-grade computer, high anti-electromagnetic interference ability and high reliability. Convenient for I/O extension, the configuration software requires a B/S architecture for remote maintenance. The real-time control of various state parameters such as switching quantity and analog quantity is realized. Product solutions provided by Advantech:
Plan: ACP - 4000 (original industrial control machine) + PCI - 1710 + PCI-1752U + WebAccess (recommended)
Main product specifications are introduced: 1. The WebAccess (recommended) is the world's first fully based on the browser and the design of the configuration software, running on Windows2000Pro/Server/WindowsXPPro/Windows2003 operating system, using B/S architecture.
Main function: - monitoring function: real-time monitoring of system equipment status through dynamic graphics.
-Control function: control the command, the script to the system device's switch, parameter setting.
-Management function: manage the user account, report and run the records to understand the state of the system.
-Web services: 1. Use the browser to connect the monitoring nodes via Internet/LAN to realize remote monitoring.
2. ACP - 4000 is a height of 4 u, standard 19 inch rack installation design, Provide 8ISA, 4PCI, 2PICMG trough passive baseslot with waterproof keyboard and a touch ban, users on its operation without using additional keyboard and mouse, meet the needs of elasticity.
3. The PCI - 1710 is a powerful low-cost multifunction PCI bus data acquisition card. 100 KS/S acquisition rate of 12 bit A/D converter, FIFO buffer card with 1K. The PCI - 1710 with 16 single-ended or 8 road differential analog input (can also be single-ended difference mix}, 2 road 12 bit D/A analog output channels, 16 road digital quantity input and output channels.
4. PCI-1752U is the DO card of high density band isolation for 64 roads.
Project description: the system consists of industrial computer application platform (ACP - 4000), as well as the I/O expansion (PCI - 1710) is used to the station 6502 electric centralized system of the switch quantity (key operational situation, the light track conditions, state of point location, lighter, etc.), analog (rail voltage, voltage switch said, all kinds of power supply voltage and current switch, etc.) collection, analysis and testing feedback.
Main functions of system components:
1. ACP - 4000 is used for computer application platform and data acquisition card expansion platform for human-computer interaction, and the output display to the engineer station is displayed at the same time. 2. The PCI - 1710 is used for collecting the scene about the switch quantity (key operational situation, the light track conditions, state of point location, lighter, etc.), analog (rail voltage, voltage switch said, all kinds of power supply voltage and current switch, etc.) of the value and status; 3. PCI-1752U control circuit breaker; 4. The web access configuration software realizes data recording, analysis, display and management functions (recommended).
Conclusion:1.The industrial computer ACP-4000 has high scalability with high anti-electromagnetic interference ability; 2. Industrial and I/O multi-function card, stable performance, and realize DI/O and AI/O functions, with high integration; 3. WEBACCESS configuration software can be managed and maintained through network.
