It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The coal conveying system coal blockage monitoring method can be applied to the application environment shown in the figure 1. Wherein, the server 102 communicates with the coal conveying program control system 104 and the image acquisition device 106 through a network. The server 104 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers. The coal handling programming system 104 may include a coal handling programming host and a display, and the image capture device 106 may be a camera or a video camera.
In one embodiment, as shown in fig. 2, a coal transportation system coal blockage monitoring method is provided, which is described by taking the method as an example applied to the server in fig. 1, and comprises the following steps:
s202, acquiring a first image acquired by an image acquisition device at a target lower opening of a coal chute;
in this embodiment, the image capturing device may be a camera.
The coal dropping pipe is generally a three-way pipe, one of three openings of the three-way pipe is used as an upper opening, the other three openings of the three-way pipe is used as a lower opening, the target lower opening can be any one of the two lower openings, and each lower opening corresponds to one coal conveying branch of the coal dropping pipe. Generally, the upper port is a coal inlet, and the two lower ports are coal outlets. Therefore, after coal of one belt falls from the coal dropping pipe, the coal can selectively fall on the lower 2 belts. However, the coal dropping pipe is not limited to a three-way pipe, and if only one belt is needed to transport coal under the coal dropping pipe of one belt in the process flow, the coal dropping pipe can be a two-way pipe.
The image acquisition device at the target lower opening can at least shoot a scene near the target lower opening of the coal dropping pipe, or at least shoot a scene on the coal conveying belt opposite to the target lower opening of the coal dropping pipe.
S204, obtaining baffle position information of the coal dropping pipe;
here, the baffle position information generally refers to position information of a three-way baffle in the coal dropping pipe, and the three-way baffle can be arranged to selectively drop coal of one belt onto 2 belts below after the coal falls from the coal dropping pipe. However, the present invention is not limited to the positional information of the three-way flapper.
The baffle position information of the coal dropping pipe can be determined according to the switching value signals read from the three-way baffle control box. The server can be directly connected to the three-way baffle control box, and the baffle position information of the coal dropping pipe can be obtained after the switching value signal is read. Or the server reads the switching value signal from the coal conveying program control system and determines the baffle position information of the coal dropping pipe according to the switching value signal; because, the coal conveying program control system collects the switching value signal.
S206, acquiring running state information of the coal conveying belt corresponding to the upper opening of the coal dropping pipe;
here, the operation state information may be information representing an operation state or information representing a stop state.
The operation state information of the coal conveying belt is generally a switching value signal read from a coal conveying belt motor control box, and the operation state information can be read by directly connecting a server to the coal conveying belt motor control box. The switching value signal can also be read by the server from the coal conveying program control system, because the coal conveying program control system collects the switching value signal, and the running state information of the coal conveying belt is determined according to the switching value signal.
S208, acquiring a second image acquired by the image acquisition device at the upper opening of the coal dropping pipe;
the image acquisition device at the upper opening of the coal dropping pipe can at least shoot the scene near the upper opening of the coal dropping pipe, or at least shoot the scene near the upper opening on the coal conveying belt towards which the target upper opening of the coal dropping pipe faces.
It should be noted that, the above steps S202, S204, S206, and S208 may not be performed in the above sequence, or may be performed simultaneously.

Specifically, whether the coal chute is blocked can be monitored according to the first image, the baffle position information, the running state information and the second image, and when the coal chute is judged to be blocked, a corresponding control strategy can be executed, for example, a shutdown instruction is sent to the coal conveying program control system, and the shutdown instruction is used for instructing the coal conveying program control system to shut down the coal conveying belt corresponding to the upper opening of the coal chute.
The coal conveying system coal blockage monitoring method comprises the steps of obtaining a first image collected by an image collecting device at a target lower opening of a coal chute, baffle position information of the coal chute, running state information of a coal conveying belt corresponding to an upper opening of the coal chute and a second image collected by the image collecting device at the upper opening of the coal chute, and carrying out coal blockage monitoring on the coal chute according to the first image, the baffle position information, the running state information and the second image. Therefore, the monitoring accuracy (alarm accuracy) is not influenced by the coal quality, the installation position of the coal blockage switch, the coal blockage switch does not need to be cleaned and debugged regularly in the coal breakage management, the false alarm or the false alarm is not easy to occur, the system operation risk is reduced, and a plurality of operation and maintenance costs are saved.

Whether the target lower port has no coal falling can be detected in a mode of carrying out image recognition on the first image.
S304, detecting whether the coal dropping branch corresponding to the target lower opening is in an open state according to the position information of the baffle, if so, entering the step S306, otherwise, not giving an alarm, and continuously detecting whether the coal dropping pipe is blocked;
here, the open state is a state in which coal can pass through.
S306, detecting whether a coal conveying belt corresponding to the upper opening of the coal dropping pipe is in operation or not according to the operation state information, if so, entering the step S308, otherwise, not giving an alarm, and continuously detecting whether the coal dropping pipe is blocked or not;

Generally, at least the individual coal conveyor belts before the coal drop pipe are shut down, or all the coal conveyor belts in the coal conveyor system are shut down. The coal belt on the coal drop tube herein may refer to one or more coal belts through which the coal flows before passing to the coal drop tube.
The coal conveying program control system can control the coal conveying belt on the coal dropping pipe to stop running in a mode of tripping the coal conveying belt.
In this embodiment, if the coal dropping pipe is still in the coal blockage state after the preset time is prolonged, the coal conveying belt on the coal dropping pipe is controlled to stop running, so that the misoperation can be reduced.

For example, the first image recognition model may be obtained by training a large number of images with coal falling at the lower opening and images without coal falling at the lower opening. The second image recognition model can be obtained by training a large number of images of coal on the coal conveying belt and images of no coal on the coal conveying belt.
In one embodiment, the first image is an image of a position on the coal conveying belt corresponding to the target lower opening, towards which the target lower opening faces; the first image recognition model and the second image recognition model are the same image recognition model, and the image recognition model is obtained through the training of a coal belt image set and a coal belt-free set.
