Step S5022: if the closed line does not exist in the image corresponding to the current image information, the shooting component is continuously controlled to move along the fixed direction.
When the closed line does not exist in the image corresponding to the current image information, the information that the vehicle door is closed still cannot be detected after the shooting assembly moves is indicated, and the shooting assembly is continuously controlled to move so as to continuously detect the abnormal vehicle door.
Referring to fig. 6, the subway traction control method further includes:
step S600: and according to the matching analysis of the shooting position information and the termination position information stored in the preset detection database, determining termination position information corresponding to the shooting position information of each abnormal vehicle door.

Step S6011: and if the shooting component does not output a correct rechecking signal before moving to the position corresponding to the final position information, outputting a manual checking signal.
When the shooting assembly does not output a correct recheck signal before moving to a position corresponding to the final position information, the specific condition of the vehicle door can not be detected or the vehicle door is not closed, and a manual checking signal is output at the moment to record the condition, so that crews can know the condition and process the condition in time.
Step S6012: and outputting a closing signal if the correct rechecking signal is output before the shooting component moves to the position corresponding to the final position information.
When the shooting component outputs a correct rechecking signal before moving to a position corresponding to the final position information, the abnormal vehicle door is in a normal closing state, and a closing signal is output at the moment to identify the situation.
Referring to fig. 7, the subway traction control method further includes:
step S700: and counting according to the normal signals to determine normal quantity information, and checking the correct signals to determine checking quantity information.
The number value corresponding to the normal number information is the total number of normal signals, namely the number of abnormal vehicle doors, of which the vehicle doors can be directly detected to be closed, when the shooting assembly moves to the corresponding shooting position; the number value corresponding to the rechecking number information is the total number of rechecking correct signals, namely the number of abnormal vehicle doors which can be detected to be closed after the shooting assembly moves; both are obtained by a counting method, which is a conventional technical means for those skilled in the art and will not be described in detail.
Step S701: and calculating the sum of the normal quantity information and the rechecking quantity information to determine sum quantity information.
The number value corresponding to the sum number information is the total number value of the detected abnormal vehicle door in the closed state, and the number value corresponding to the normal number information is added with the number value corresponding to the rechecking number information to obtain the vehicle door.
Step S702: and judging whether the quantity value corresponding to the sum quantity information is consistent with the quantity value corresponding to the abnormal quantity information.
The purpose of the judgment is to know whether the abnormal vehicle door is actually not closed, so that the subsequent control of the vehicle is facilitated.
Step S7021: if the number value corresponding to the sum number information is inconsistent with the number value corresponding to the abnormal number information, outputting a non-closing signal and maintaining the current state of the traction equipment.
When the number value corresponding to the sum number information is inconsistent with the number value corresponding to the abnormal number information, at least one vehicle door is not closed, and a non-closing signal is output at the moment to record the situation, so that crews can timely learn the situation, and meanwhile, the state that traction equipment is stopped currently is maintained, so that the vehicle cannot start to run.
Step S7022: and if the number value corresponding to the sum number information is consistent with the number value corresponding to the abnormal number information, controlling the traction equipment to start operation.
When the number value corresponding to the sum number information is consistent with the number value corresponding to the abnormal number information, the condition that the vehicle door is not closed is not existed, the vehicle can normally run at the moment, and the traction equipment is controlled to start operation so as to reduce the condition that the vehicle running is influenced.
