Abstract
The invention relates to a buried switch machine control system for a tramcar. The buried switch machine control system for the tramcar comprises a control host, a relay, an I/O (Input/Output) board card and a switch machine. The control host is used for receiving a control command of an operation terminal; the I/O board card is used for collecting state information; and the control host is used for performing logical judging processing according to collected information. When a point section is not occupied, the position of the switch machine is inconsistent with the position where the switch machine is to be rotated, a control handle is not available for the switch machine, the point section is not blocked and a point is not singly locked, the I/O board card outputs corresponding control information and drives the relay to rotate the switch machine to a corresponding position; and after the I/O board card collects information that the switch machine has been rotated to the corresponding position, the control host stops driving the corresponding relay and disconnects a driving power supply of the switch machine. According to the buried switch machine control system for the tramcar, provided by the invention, logic processing of the control host of the switch machine and a relay interface control circuit are combined so that the buried switch machine is preferably controlled and safe, reliable and efficient operation of the system is ensured.
Description
Technical field
The present invention relates to a kind of tramway train field apparatus control system, specifically the buried railway switch control system of modern tram.
Background technology
At present, in modern tram signal system, the control command that switch control system issues according to operating terminal handles track switch, and then to realize to the path clustering of train walking buried switch machine as the important trackside function unit of Modern Transportation Technology, be related to the operation of whole signal system, therefore in order to ensure the carrying out that whole signal system is safe, reliable, efficient, actv. must be implemented to buried switch machine and controlling.
Summary of the invention
The buried railway switch control system of a kind of safe, reliable, efficient tramway train is the invention provides for above problem.
Technical scheme: the invention provides the buried railway switch control system of a kind of tramway train to overcome the above problems, it is characterized in that: comprise main control system, relay, I/O board, switch machine.
Main control system receives the control command of operating terminal, whether I/O board collection section with a switch or switches status information, the positional representation information of switch machine, switch machine have handle to control, whether section with a switch or switches is blocked, track switch whether by monolock, main control system combine gather information carry out Logic judgment process.
When section with a switch or switches is vacant, switch machine position is with the position needing to rotate is inconsistent, switch machine controls without handle, section with a switch or switches is not blocked, track switch is by monolock, then I/O board exports corresponding control information, drive relay, make switch machine turn to corresponding position; When I/O board collects after switch machine turned to corresponding position, main control system stops driving corresponding relay, disconnects the driving power of switch machine.
When the position that section with a switch or switches is vacant, switch machine position is rotated with needs is inconsistent, switch machine has handle to control, no matter whether section with a switch or switches is blocked, no matter whether track switch is by monolock, then I/O board can not drive corresponding control relay, turns to corresponding position by the lever operated switch machine that makes.
When section with a switch or switches take or switch machine position with need the position consistency of rotating section with a switch or switches is blocked or track switch by monolock time, I/O board does not drive corresponding control relay, and switch machine does not rotate.
Described relay comprises permission and handles relay, left-hand rotation relay, handle state relay, right-hand rotation relay, left bit representation relay, right bit representation relay.
When main control system receives the control command of the left-hand rotation of operating terminal, I/O board gathers vacant, the switch machine position of section with a switch or switches and the position needing to rotate is inconsistent, switch machine controls without handle, section with a switch or switches is not blocked, track switch is by monolock, then I/O board exports the control information of left-hand rotation, drive and allow to handle relay, left-hand rotation relay, now driving power is connected, and switch machine turns left; When I/O board collects the excitation information of left bit representation relay, namely switch machine is after a left side turns to corresponding position, and main control system stops driving and allows to handle relay, left-hand rotation relay, disconnects the driving power of switch machine.
When main control system receives the control command of the right-hand rotation of operating terminal, I/O board collects that section with a switch or switches is vacant, switch machine position is with the position needing to rotate is inconsistent, switch machine controls without handle, section with a switch or switches is not blocked, track switch is by monolock, then I/O board exports the control information of turning right, drive and allow to handle relay, right-hand rotation relay, now driving power is connected, and switch machine is turned right; When I/O board collects the excitation information of right bit representation relay, namely switch machine is after the right side turns to corresponding position, and main control system stops driving and allows to handle relay, right-hand rotation relay, disconnects the driving power of switch machine.
When section with a switch or switches is vacant, once switch machine has, handle controls, no matter whether section with a switch or switches is blocked, no matter whether track switch is by monolock, then handle state relay will fall, switch machine power supply double break is left, turn to corresponding position by the lever operated switch machine that makes, safety precaution is carried out to operating personal.
As in specific time, I/O board does not collect the left bit representation relay of switch machine or the excitation information of right bit representation relay, main control system stops driving corresponding relay, disconnects the driving power of switch machine, protection switch machine motor.
Main control system is in output control process, if corresponding section with a switch or switches has train occupation when namely switch machine has started to rotate, main control system guarantee driving switch machine turns to the position that former control command specifies, guarantees the integraty controlled.
Left-hand rotation relay, its contact of right-hand rotation relay adopt interlock mode to ensure the safety of circuit.
Allowing to handle relay adopts independent double break to control, and prevents from making switch machine misoperation during mix line fault.
Described main control system is three fail-safe computers getting two.
Described switch machine is buried switch machine.
Described I/O plate gathers the normal opened contact of relay.
Beneficial effect: the logical process and the relay interface control circuit that present invention incorporates railway switch control main frame, solve the control of buried switch machine well, guarantee security of system, reliably, efficiently run, the practical application of modern tram can be adapted to.
