[0032] Figure 3A schematic diagram of a downhole equipment status detection device based on multimodal data fusion provided in an embodiment of the present disclosure. DETAILED DESCRIPTION

[0033] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0034] Specifically, the downhole equipment status detection method based on multimodal data fusion according to an embodiment of the present disclosure is described below with reference to the accompanying drawings. Figure 1 A flow chart of a method for detecting downhole equipment status based on multimodal data fusion provided in an embodiment of the present disclosure.

[0035] Step 101, obtaining the start / stop status text information and monitoring video information of the downhole equipment at the same time.

[0036] In some embodiments of the present disclosure, the start-stop status text information may be at least one of the following: the start-stop status text information of the downhole equipment detected during the inspection process, the start-stop status text information reported by the downhole equipment, and the start-stop status text information entered by the operator.

[0037] Among them, the text information on the start and stop status of the underground equipment detected during the inspection process refers to the start and stop status information determined when the inspection robot inspects along the specified route. The inspection detection result can be the start and stop text information directly generated or recorded, or it can also be a voice broadcast or a fixed prompt tone of the start and stop status. If the inspection detection result is a voice broadcast of the start and stop status issued by the inspection robot, the start and stop status information contained in the voice broadcast can be identified by a large language model to generate the start and stop status text information. If the inspection detection result is a fixed prompt tone, the start and stop status of the underground equipment can be determined according to the pre-established mapping relationship between the prompt tone and the start and stop status, and then the start and stop status text information is generated. The start and stop status text information reported by the underground equipment is a text description of the start and stop status generated by the underground equipment according to its own parameters, and is reported to the system or platform related to the corresponding equipment of the coal mine.

[0038] If the start-stop status text information includes multiple types of the start-stop status text information of the downhole equipment detected during the inspection, the start-stop status text information reported by the downhole equipment, and the start-stop status text information entered by the operator, the multiple types of text information are compared, and if the information is consistent, any type of text information can be used as the start-stop status text information. If the information is inconsistent, the start-stop status text information of the downhole equipment detected during the inspection is used as the start-stop status text information.

[0039] The monitoring video information is the downhole equipment monitoring video collected by a video acquisition device (such as a camera), and the video includes all downhole equipment or part of the downhole equipment.

[0040] Step 102: Input the start / stop status text information into a pre-trained text-image generation model to obtain a plurality of first images containing downhole equipment. The text-image generation model has learned the ability to generate corresponding first images according to the start / stop status text information of the downhole equipment.

[0041] It should be noted that the text-image generation model is pre-trained using historical images and historical start-stop status text information of downhole equipment, and can generate multiple first images of corresponding downhole equipment based on the start-stop status text information. Among them, the position of a certain marker in the multiple first images can reflect the start-stop status of the downhole equipment. As an example, assuming that the downhole equipment is a belt, and the start-stop status text information is the stop state, the displacement of a certain marker on the belt remains basically unchanged between the multiple first images generated based on the text information. Optionally, the text-image generation model can adopt the CLIPBERT model based on sparse sampling video and language learning.

[0042] Step 103: extract image frames from the monitoring video information to obtain multiple video frame information.

[0043] Step 104: synthesize the plurality of first images and the plurality of video frame information to generate an image set.

[0044] As an example, N video frame information is extracted from the monitoring video information, and the text-image generation model generates X consecutive first images based on the start-stop status text information. The N video frame information and the X consecutive first images are synthesized to generate an image set containing N+X images. Since the start-stop status text information and the monitoring video information are collected at the same time, there is no requirement for the order of the first image and video frame information in the image set. The first image and video frame information are synthesized to increase the data source for start-stop status recognition. The start-stop status of the downhole equipment can be jointly judged through multi-modal data, which can improve the detection accuracy.

[0045] In actual coal mine scenarios, there are situations such as poor camera signals, obstacles, unstable data, and failures. If the camera fails to collect monitoring, the monitoring video information is empty, N = 0, and the image set only includes X consecutive first images generated by the text-image generation model based on the start-stop status text information. Therefore, the monitoring video information is supplemented with the start-stop status text information to avoid the problem of the inability to detect the start-stop status of the equipment due to the loss of video information.

[0046] Step 105 , using a visual detection algorithm to perform status detection on the downhole equipment in the image set, and obtaining a first start / stop status detection result of the downhole equipment.

[0047] In some embodiments of the present disclosure, a visual detection algorithm may be used to detect the downhole equipment in the image set to determine the start and stop status of the downhole equipment. As a possible implementation method, the first start and stop status detection result of the downhole equipment may be obtained by using the LK pyramid optical flow algorithm combined with the wide flow time series feature analysis detection method. Alternatively, other visual detection algorithms may be used, which are not limited in the present disclosure.

[0048] In order to further improve the accuracy of downhole equipment status detection, in some embodiments of the present disclosure, in addition to the start / stop status text information and monitoring video information, sensor data sources may be added to jointly determine the start / stop status of the downhole equipment. Figure 2 FIG. 1 is a flow chart of another method for detecting downhole equipment status based on multimodal data fusion provided by an embodiment of the present disclosure. Figure 2 As shown, the start-stop status text information, monitoring video information and sensor data of the downhole equipment at the same time are obtained. Sensors such as laser radars, equipment real-time data sensors, etc. collect the real-time operating speed, start-stop status, etc. of the downhole equipment. The second start-stop status detection result of the downhole equipment is determined according to the sensor data. If the status data is 1, it means start, 0 means stop, the speed is greater than 0, it means start, and the speed is less than or equal to 0, it means stop. Combined with the first start-stop status detection result and the second start-stop status detection result, the start-stop status of the downhole equipment is determined. For example, the first start-stop status detection result and the second start-stop status detection result can be weighted and summed to determine the start-stop status of the downhole equipment. Alternatively, the first start-stop status detection result and the second start-stop status detection result can be compared. If the results are consistent, the detection result is output. If they are inconsistent, an error message is generated and fed back to the terminal to remind the staff to ensure the safety of the personnel in construction.

[0049] By implementing the embodiments of the present disclosure, the start / stop status of the underground equipment is comprehensively judged based on the start / stop status text information and monitoring video information of the underground equipment, enriching the data source and improving the accuracy of equipment status detection. In addition, when there is a problem with the video information, the start / stop status text information is used to supplement the data, which can avoid the problem of the equipment start / stop status being unable to be detected or inaccurately detected due to the loss of video information to a certain extent. The present disclosure helps to reduce the loss of personnel and property at the coal mine site, reduce the possibility of production accidents, and ensure the safety of workers underground in the coal mine.
