Specifically, the reasons for train traction blocking specifically include abnormal parking brake, abnormal train door closing, no traction permission signal and the like, and the train traction blocking faults caused by different reasons can cause the change of state data of the train, so that the corresponding relation between the state data of the train and the reasons for train traction blocking is constructed in advance according to the circuit traction instruction forming conditions and experience, the reasons for train traction blocking faults can be diagnosed later, and it can be understood that when the train has traction intention, and all kinds of state data are in the corresponding preset range, the circuit traction instruction can be formed.
Specifically, the state data corresponding to the parking brake of the train may include a release state of a parking brake relay, an air pressure value of a parking brake cylinder, and the like, and the state data corresponding to the abnormal closing of the train door may include a switch state of the relay corresponding to the good closing of the door, wherein the states, the air pressure values, and the traction permission signals of the various relays may be acquired from a TCMS (Train Control and Management System, a train control and management system), without adding additional hardware equipment, and cost is saved.
Of course, the reasons for blocking the train traction may include other reasons besides the three reasons described above, and the present application is not limited herein.
Step 2: when the train has traction intention, judging whether a circuit traction instruction exists, if not, entering a step 3;
specifically, when an ATO (Automatic Train Operation) traction instruction or a driver traction instruction indicates that the train has traction intention, but if an abnormality exists in the traction circuit, the ATO traction instruction or the driver traction instruction is blocked, and a circuit traction instruction cannot be formed (i.e. no circuit traction instruction exists), so that the traction inverter cannot realize the traction function, and at the moment, the train is in a traction blocking fault state, and the fault cause needs to be diagnosed, so that a driver can take corresponding measures in time.
Step 3: acquiring current state data of a train, and determining the current train traction blocking reason through the current state data and the corresponding relation;
specifically, if the train has traction intention but does not have a circuit traction instruction, the traction blocking reason is diagnosed, the current state data of the train is firstly obtained, the train traction blocking reason corresponding to the current state data is determined according to the current state data and the corresponding relation constructed in the step 1, if the corresponding relay is in an open state when the train door is normally closed, but the obtained current state data indicates that the relay is in a closed state, the reason for causing the train traction blocking fault is that the door is not closed.
Step 4: prompting prompt information corresponding to the current train traction blocking reason so that a driver can execute corresponding measures according to the prompt information.
As a preferred embodiment, the process of prompting the prompting information corresponding to the current train traction lockout reason is specifically as follows:
and prompting information corresponding to the current train traction blocking reason through a display screen arranged in the cab.
Specifically, after determining the current train traction blocking reason in step 3, generating prompt information corresponding to the current train traction blocking reason, where the prompt information may refer to the reason causing the current train traction blocking fault, or may refer to emergency treatment measures corresponding to the current train traction blocking reason, so that a driver can conveniently know the fault reason and take corresponding measures in time.
Specifically, corresponding prompt information can be prompted through the display screen arranged in the cab, so that a driver can conveniently check the prompt information, and meanwhile, hardware equipment is not required to be additionally added, so that the cost is reduced.
The application provides a train traction lockout diagnostic method, which comprises the following steps: pre-constructing a corresponding relation between the state data of the train and the train traction blocking reason; when the train has traction intention, judging whether a circuit traction instruction exists or not; if not, acquiring current state data of the train, and determining the current train traction blocking reason through the current state data and the corresponding relation; prompting prompt information corresponding to the current train traction blocking reason so that a driver can execute corresponding measures according to the prompt information.

the target cab is a cab which receives a key instruction.
It can be understood that the ATO traction command can be directly obtained from the data sent to the TCMS by the ATC (Automatic Train Control, train control system), and the driver traction command can be determined by considering that the train generally includes two cabs, namely, cab a and cab B, respectively, and assuming that the current train is not in the ATO mode, the driver acquisition value of cab a is greater than a preset value, and there is a key command in cab a (cab a is a target cab), and that the current train is in a non-emergency braking state, a non-service braking state, and a non-quick braking state, it is indicated that cab a generates the driver traction command. In general, only one cab will have a key command, and cabs without a key command are considered invalid even if the driver acquisition value is greater than the preset value.
The collected value of the driver controller can be a current value, and when the collected current value is larger than a preset value, the driver is informed that the traction push rod is pushed to a traction position.
As a preferred embodiment, if the current train traction blocking cause is abnormal in the parking brake, judging whether the parking brake release loop is abnormal, if so, judging that the train traction blocking cause is abnormal in the parking brake release loop, and if not, judging that the train traction blocking cause is not released in the parking brake;

if the current train traction blocking source is the no traction permission signal, judging whether the ATC cutting loop is abnormal, if so, judging that the train traction blocking source is the ATC cutting loop abnormality, and if not, judging that the train traction blocking source is the ATC no traction permission signal.
Specifically, if the parking brake relay is in a non-released state and the air pressure value is in a non-released state, the parking brake of the train is indicated to be in a stopped braking non-released state, if the parking brake relay is in a released state and the air pressure value is in a non-released state, the parking brake release loop is indicated to be abnormal, and at the moment, the non-released parking brake of the carriage or the prompt information corresponding to the abnormal parking brake release loop is correspondingly prompted through the display screen, so that a driver overhauls the corresponding carriage or closes a parking brake release bypass; judging whether the door safety loop is abnormal or not, and the same is true; if the train traction blocking fault is caused by a traction-free signal, judging whether the ATC does not send out a traction permission signal, if so, prompting prompt information corresponding to the ATC does not send out the traction permission signal so as to facilitate a driver to cut off the ATC, judging whether an ATC cutting loop is abnormal, if so, leading the ATC to be incapable of cutting off, prompting prompt information corresponding to the ATC cutting loop abnormality due to the influence of the traction permission signal, and facilitating a driver to process the ATC cutting loop.
In summary, the method and the device have the advantages that the reasons for blocking the hardware circuit instruction of the train can be rapidly positioned based on the conditions formed by the circuit traction instruction, so that the driver is prompted to correspond to emergency treatment measures, the time for processing the train faults is reduced, the fault processing efficiency is improved, and the influence of the train faults is reduced.
