Problems solved by technology

[0003] The current signal maintenance and troubleshooting work mainly relies on the signal microcomputer monitoring system to establish a network for real-time monitoring, but the signal microcomputer monitoring system focuses on result management, and there are obvious deficiencies in process management, and it is impossible to obtain regularity through the collection of monitoring data In addition, although signal microcomputer monitoring equipment has been widely used in the field, many still rely on manual inspection of data changes. In the case of a large amount of data, manual analysis of data correlation and historical data comparison analysis is not competent.
Although almost all kinds of data of signal equipment are collected, the mining and logical analysis of signal data, data sharing and fusion processing are not enough
Except that the signal microcomputer monitoring system has a simple logic to judge that some electrical quantities exceed the standard alarm, other aspects cannot play the role of real-time automatic alarm and monitoring the operation of the signal system

Abstract

The invention discloses an industrial control signal detection system and a detection method; the detection system comprises a data collecting module which collects real-time status data of equipment electrical features, and a historical process database which is connected with the data collecting module and used for storing the real-time status data collected by the data collecting module; the detection system further comprises a signal process predicating model which is connected with the historical process database and establishes correspondence between signal input and output in the electrical features based on the data inside the historical process database; the signal process predicating model obtains a predicated output signal based on the real-time input signal collected by the data collecting module, and sends the predicated output signal to a signal filter; the signal filter receivers the predicated output signal from the signal process predicating model and the real-time output signal collected by the data collecting module, and compares the signals, if the feature of the corresponding real-time output signal accords with the feature of the predicated output signal, then the real-time output signal is judged to be an effective executable signal; otherwise, the real-time output signal is judged to be a negative non-executable signal.

Description

technical field [0001] The invention belongs to the field of information security of industrial control systems, specifically, it relates to a detection system for industrial control signals, more precisely, it relates to a detection system for signals of trains such as high-speed railways and subways; the invention also relates to an industrial control signal detection system detection method. Background technique [0002] The train control system is the integration of various signal equipment and subsystems and their auxiliary equipment. System integration is one of the key technologies of high-speed rail signaling, which is directly related to the safety of the system. Functional Requirements Specification (FRS), System Requirements Specification (SRS) and System Interface Specification (FIS) of train control system are the main basis for system integration. The current train control system integration focuses on the interface technology between different equipment or s...
