Intelligent acquisition driving device

Abstract

The invention relates to an intelligent collection-drive device which comprises a motherboard, an intelligent input board and an intelligent output board. The motherboard comprises a power supply input module, a CAN interface module, a CAN address setting module, a slot of the intelligent input board and a slot of the intelligent output board; the intelligent input board comprises two microprocessors, a monitoring circuit, a self detection and drive circuit; the intelligent output board comprises two microprocessors, a monitoring circuit, a self detection and drive circuit; the intelligent input board and the intelligent output board are respectively inserted on the slot of the intelligent input board and the slot of the intelligent output board of the motherboard. The intelligent collection-drive device brings a deep revolution on the aspect of a computer interface for a computer interlocking system, a microcomputer monitoring system, and the like, leads an interface mode to be fundamentally changed, leads a hypogynous processing system and the interface part to have the independence and isolation to the utmost extent and obtains essential upgrading and convenience on the aspects like safety, control, debugging, expansibility, and the like.

Description

technical field [0001] The invention relates to a data collection and driving device used in a railway computer interlocking system, a dispatching centralized system, a microcomputer monitoring system, etc., in particular to an intelligent collection and driving device. Background technique [0002] With the wide application of computer interlocking system, dispatching centralized system, and microcomputer monitoring system in the field of railway signals, the safety of switch quantity collection and driving has attracted people's attention. Before the introduction of foreign equipment, the interlocking systems developed by various computer interlocking system providers in the railway basically realized the safety output through dynamic output. With the practical application in the past ten years, the defect of dynamic output has become more and more prominent. The high failure rate of the channel leads to the decrease of the safety of the system and becomes the main bottlen...

AI Technical Summary

Problems solved by technology

With the practical application in the past ten years, the defect of dynamic output has become more and more prominent. The high failure rate of the channel leads to the decrease of system security and becomes the main bottleneck of system development and upgrade.

[0003] In the systems listed above, the digital acquisition board itself does not have computing functions, and cannot adopt reliable acquisition algorithms, thus affecting the stability of the acquisition board state

In addition, because the integration of the acquisition and driver board and the central logic processor is relatively complicated, most of them use non-industrial standard bus connection methods, which cannot solve the problem of channel redundancy, and cannot independently design the acquisition and driver board, which affects the reliability of the system. scalability, scalability and maintainability
