Optionally, the first ATC cut-off unit, the second ATC cut-off unit, and the output box outputting the zero-speed control signal are connected in series, and when the operating state of the signal system is abnormal or the control state of the train is not controlled, the first ATC cut-off unit and/or the second ATC cut-off unit operates to control the cut-off switch of the first ATC cut-off unit and/or the second ATC cut-off unit to be located at the cut-off position, and at this time, the cut-off switch of the first ATC cut-off unit and/or the second ATC cut-off unit outputs the first level signal (0 level signal).
The zero-speed signal control circuit is an active high-level circuit. Therefore, after the output plug box receives the first level signal, the zero speed signal of the output plug box is disconnected, and the output state is that the control signal containing the zero speed signal is not output, so that a zero speed relay in the zero speed control circuit cannot be normally sucked up, a train cannot be controlled according to the zero speed signal of the signal system, and the function of timely cutting off the control signal output by the signal system when the signal system fails and the vehicle is not controlled is met.
When the running state of the signal system is normal and the control state of the train is controlled, the first ATC cut-off unit and the second ATC cut-off unit act to control the cut-off switches of the first ATC cut-off unit and the second ATC cut-off unit to be located at a control position and output the second level signal; the output box is specifically configured to output the control signal including a zero-speed signal in the output state when the second level signal is received.
Optionally, the signal system normally controls the train when the operation state of the signal system is normal and the control state of the train is control. At this time, the first ATC cut-off unit and the second ATC cut-off unit operate, the cut-off switches of the first ATC cut-off unit and the second ATC cut-off unit are controlled to be located at the control bit, and the cut-off switches of the first ATC cut-off unit and the second ATC cut-off unit output the second level signal (1 level signal).
After the output plug box receives the second level signal, the output plug box can normally output a control signal containing a zero-speed signal, a zero-speed relay in the zero-speed control circuit can be normally sucked up, the train can be normally controlled according to the zero-speed signal of the signal system, and the train can be controlled according to the control signal output by the signal system when the signal system is normal and controls the train.
In the embodiment, the first ATC removing unit and the second ATC removing unit can realize the function of timely removing the control signal output by the signal system when the signal system has a fault and does not control the vehicle only by performing real-time action according to the running state and the control state of the signal system, and can control the train according to the control signal output by the signal system when the signal system is normal and controls the vehicle; when the signal system fails and the vehicle is not controlled, any one of the first ATC cut-off unit and the second ATC cut-off unit can cut off the control signal output by the signal system, so that the operation is convenient and fast; meanwhile, the situation that a contact cannot be closed when one cut-off switch is used is met, ATC can be cut off through the other cut-off switch, system safety is provided, and practicability is high.
In addition to the above embodiments, in this embodiment, when the signal control circuit includes a traction cut-off control circuit, both the first ATC cut-off unit and the second ATC cut-off unit are connected in parallel to the output box, and the output box is connected in series to the traction cut-off control circuit.
Optionally, the first ATC cut-off unit in the car and the second ATC cut-off unit on the chassis adopt a parallel design for the second signal control circuit with low level active, and the design of such a switching circuit is specifically described below by taking the traction cut-off control circuit as an example.
As shown in fig. 4, the first ATC cut unit S01 is connected in parallel with the second ATC cut unit S01 through a connection terminal, and then connected in parallel with the output box a 01; the output box a01 is connected in series with the traction cut-off control circuit. Wherein, the traction cutting-off control circuit is arranged on the chassis.
The switching circuit is used for enabling a relay in the traction cut-off control circuit to be electrified according to the traction cut-off output by the output plug box, and obtaining the train traction cut-off so as to control the traction cut-off of the train.
It should be noted that another second signal control circuit may be connected to the first ATC cut-off unit, the output jack box, and the second ATC cut-off unit in accordance with the connection method of the pull-off cut-off control circuit.
The second ATC cutting unit and the second ATC cutting unit are connected with the traction cutting control circuit in parallel, so that ATC can be cut off when the carriage operates independently, the ATC can be cut off when the chassis operates independently, meanwhile, a cutting switch is satisfied, the contact cannot be closed, the ATC can be cut off through the other cutting switch, system safety is improved, operation is simple, and practicability is high.
On the basis of the above embodiment, in this embodiment, when the operating state of the signal system is abnormal or the control state of the train is not controlled, the first ATC cut unit and/or the second ATC cut unit operates to control the cut switch of the first ATC cut unit and/or the second ATC cut unit to be located at a cut position, and output the first level signal; the output plug-in box is specifically used for outputting the control signal containing the traction cutting-off signal in the output state under the condition of receiving the first level signal;
optionally, if the signal system outputs the traction cut-off signal by mistake when the operating state of the signal system is abnormal or the control state of the train is not controlled, the traction cut-off control circuit may not obtain the actual traction cut-off signal of the train, which may cause that the traction safety of the train cannot be established and the train cannot be moved.
In this scenario, in order to avoid the signal system from outputting the traction cut-off signal by mistake, when the signal system does not participate in controlling the vehicle or has a fault, the ATC cut-off unit acts to cut off the control signal output by the signal system, so that the control signal output by the signal system does not influence the train to obtain a real traction cut-off signal, and does not influence the traction safety establishment.
Optionally, the first ATC removal unit, the second ATC removal unit, and the output trunk outputting the zero-speed control signal are connected in parallel to bypass the output trunk, and when the operating state of the signal system is abnormal or the control state of the train is not controlled, the first ATC removal unit and/or the second ATC removal unit operate to control the removal switch of the first ATC removal unit and/or the second ATC removal unit to be located at the removal position, and at this time, the removal switch of the first ATC removal unit and/or the second ATC removal unit outputs the first level signal (0 level signal).
The cut-off control circuit is an active low circuit due to the traction. Therefore, when the cut-off switch of the first ATC cut-off unit and/or the second ATC cut-off unit outputs the first level signal (0 level signal), the first ATC cut-off unit and/or the second ATC cut-off unit and the output jack form a closed loop, that is, the output jack is short-circuited.
At the moment, the traction cut-off signal of the output plug box is bypassed, and the output state is that a control signal containing the traction cut-off signal is not output, so that the traction cut-off control circuit cannot carry out traction safety cut-off control on the train according to the traction cut-off signal of the signal system, and the function of timely cutting off the control signal output by the signal system when the signal system fails and the vehicle is not controlled is met.
When the running state of the signal system is normal and the control state of the train is controlled, the first ATC cut-off unit and the second ATC cut-off unit act to control the cut-off switches of the first ATC cut-off unit and the second ATC cut-off unit to be located at a control position and output the second level signal; the output plug-in box is specifically configured to, when the second level signal is received, output the control signal including a traction cut-off signal in the output state.
Optionally, the signal system normally controls the train when the operation state of the signal system is normal and the control state of the train is control. At this time, the first ATC cut-off unit and the second ATC cut-off unit operate, the cut-off switches of the first ATC cut-off unit and the second ATC cut-off unit are controlled to be located at the control bit, and the cut-off switches of the first ATC cut-off unit and the second ATC cut-off unit output the second level signal (1 level signal).
After the output plug box receives the second level signal, the output plug box is not short-circuited, a control signal containing traction cut-off can be normally output, the traction cut-off control circuit can normally control the train according to the traction cut-off signal of the signal system, and the train can be controlled according to the control signal output by the signal system when the signal system is normal and controls the train.
In the embodiment, the first ATC removing unit and the second ATC removing unit can realize the function of timely removing the control signal output by the signal system when the signal system has a fault and does not control the vehicle only by performing real-time action according to the running state and the control state of the signal system, and can control the train according to the control signal output by the signal system when the signal system is normal and controls the vehicle; when the signal system fails and the vehicle is not controlled, any one of the first ATC cut-off unit and the second ATC cut-off unit can cut off the control signal output by the signal system, so that the operation is convenient and fast; meanwhile, the condition that one cutting switch cannot be closed when a contact is generated can be met, and the ATC can be cut through the other cutting switch, so that system safety is provided, and the practicability is high.
