specific Embodiment approach

[0019] The functions of the two general-purpose I / O modules should at least meet the following design requirements, and should have: digital input channels, digital output channels, analog input channels, analog output channels, and frequency input channels. The number of channels of each function can be adjusted during actual design, and the number of channels enumerated below does not limit the present invention, and the specific embodiments are as follows:

[0020] Digital input channel: realize the acquisition of 4 switch values;

[0021] Digital output channel: Realize 2 relay outputs, and each relay outputs two sets of normally open and normally closed dry contacts for application selection;

[0022] Analog input channel: realize the acquisition of 2 analog signals, such as the acquisition of pressure signal, primary voltage and primary current;

[0023] Analog output channel: realize the output of 1 analog signal, such as the output of signals such as speed, speed limi...

Abstract

Disclosed is a secure computer platform adopting a double 2-vote-2 security redundancy architecture. The secure computer platform is divided into a main control layer and an execution layer. Two general I/O execution modules are designed for the execution layer to be integrated and selected by the secure computer platform; wherein the execution modules of two general I/Os are respectively a general security I/O module and a general non-secure I/O module which have consistent basic functions and are only divided into a secure module and a non-secure module from the aspect of architecture designfor different application environments to select; the functions of the two universal I/O modules integrate common I/O functions such as input and output of digital quantity, output and output of analog quantity, input and acquisition of frequency quantity and the like. The system requirements can be met only by configuring a proper number of universal modules when the platform system is integrated. The IO module which is complete in function and extremely good in universality is designed and used for integration of a safety computer platform, and maintainability and configuration difficulty of the platform are greatly reduced.

Description

technical field [0001] The invention relates to the realization field of a railway safety computer platform, in particular to a safety computer platform which adopts a general I / O module to realize system integration. Background technique [0002] With the development of railway transportation, the development of train signal control related equipment is diversified. Higher requirements are put forward for the safety and maintainability of train control equipment. As a basic general-purpose platform, the security computer platform can flexibly develop application services and integrate various input and output (I / O) modules to support various application environments. It is characterized by layered and bus architecture, each layer contains relatively independent modules that can be integrated, each module can contain software programs, and the modules can communicate through the bus. The safety computer platform system suitable for railway train control system requires not...
