Referring to fig. 1, fig. 1 is a schematic flow chart of a train connection state detection method according to an embodiment of the present application. The train coupling state detection method comprises the following steps:
s101, when a target tank car exists behind the target train, judging whether the target train and the target tank car are both in a running state, if so, executing a step S102; if not, the flow is ended.
In this embodiment, the method may be executed by a train connection state detection device, and specifically, the train connection state detection device may be run on a computing device such as a computer and a server, which is not limited in this embodiment.
In this embodiment, the train connection state detection device may also be operated on an intelligent device such as a smart phone or a tablet computer, which is not limited in this embodiment.
In the embodiment of the application, the motion state of the target train and the motion state of the target tank car can be detected through the motion sensor and the speed sensor, and then whether the target train and the target tank car are both in the running state or not is judged according to the motion state of the target train and the motion state of the target tank car.
In the embodiment of the application, when the target train and the target tank car are judged not to be both in the running state, the three conditions are divided, wherein the first condition is that the target train is in the running state, and the target tank car is not in the running state; the second is that the target train is not in a running state, and the target tank car is in a running state; the third is that the target train is not in a running state, and the target tank car is not in a running state.
In the embodiment of the application, when judging whether the target train and the target tank car are both in the running state, if the first condition or the second condition is judged, an alarm prompt can be directly output to prompt the motion states of the target train and the target tank car; if the third situation is judged, the target train can be controlled to perform trial-pull operation, then whether the target tank car can move according to the trial-pull movement of the target train is judged, and if the third situation is judged, the step S102 is executed.
In the embodiment of the present application, the target train may be an artificially driven vehicle, an unmanned vehicle, a semi-autonomous vehicle, or the like, and the embodiment of the present application is not limited thereto.
