Intelligent acquisition drive equipment

Abstract

The present invention relates to an intelligent acquisition drive device, the device includes a motherboard, an intelligent input board, and an intelligent output board, and the motherboard includes a power input module, a CAN interface module, a CAN address setting module, an intelligent input board slot, Intelligent output board slot, the intelligent input board includes dual microprocessors, monitoring circuit, self-test and drive circuit, the intelligent output board includes dual microprocessors, monitoring circuit, self-test and drive circuit , the intelligent input board and the intelligent output board are respectively inserted into the intelligent input board slot and the intelligent output board slot of the motherboard. The present invention brings a profound change in computer interface to computer interlocking system, microcomputer monitoring system, etc., and causes fundamental changes in the interface mode, so that the lower processing system and the interface part have the greatest degree of independence and isolation It has been substantially improved and facilitated in terms of security, control, debugging, and scalability.

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
