Full-electronic turnout control module

Abstract

The embodiment of the invention discloses a full-electronic turnout control module. The Full-electronic turnout control module is connected between an interlocking logic unit and an outdoor point machine of a computer interlocking system and comprises a logic control unit and a strong electricity control unit which are mutually connected. The logic control unit is used for receiving a control instruction of an operating and expressing machine in the computer interlocking system through the interlocking logic unit and controlling the strong electricity control unit according to the control instruction. The strong electricity control unit is used for controlling the outdoor point machine by executing the control instruction. The Full-electronic turnout control module has the characteristicsof high integration and small size.

Description

technical field [0001] The embodiment of the present invention relates to track control technology, in particular to an all-electronic turnout control module. Background technique [0002] In the current signal system of our country, the interlocking system is used for station signal control, and the computer interlocking equipment has been popularized and applied for nearly two decades, and a relatively mature product structure and technical conditions have been formed. The control logic and external structure of the current computer interlocking equipment are still inherited from the 6502 electrical centralized interlocking system, and its external equipment still uses the gravity type safety relay as the medium to carry out safety input and output control, by controlling the gravity type safety relay coil to pick up or fall Manipulate the action of outdoor equipment, and obtain the status of outdoor equipment through the state of relay contacts. [0003] Such as figure ...

AI Technical Summary

Problems solved by technology

[0006] 1. Large size: a single gravity relay is relatively large in size, and at least 6 relays are required to realize a turnout control circuit, and the entire control circuit takes up a lot of space;

[0007] 2. Complex construction: Relays, buttons, fuses, buttons and other devices used in the turnout control circuit must be wired. The number of wiring is large, the construction is difficult, and it is easy to make mistakes. It is difficult to check and check;

[0008] 3. No monitoring: There is no monitoring circuit in the turnout control circuit, and the operating parameters during the turnout control process cannot be detected, and status analysis and fault prediction cannot be performed; if monitoring is required, a separate monitoring system needs to be added, which is complex and costly ;

[0009] 4. Difficulty in maintenance: There are many devices in the turnout control circuit and the wiring is complicated. Once a fault occurs, it is difficult to quickly locate the cause of the fault, which brings great pressure to system maintenance.
