Description

Technical Field

[0001] The present invention belongs to the technical field of coal mine monitoring, and in particular relates to a dust removal camera device based on UWB positioning, AI analysis and control output. Background Art

[0002] The coal mine working face is the first production site of coal mining. It has the characteristics of small working space, many mechanical equipment, poor visual environment, high temperature, and large coal dust. Therefore, workers need to wear masks. At present, the equipment involved in monitoring workers to achieve protection effects on the market includes but is not limited to the following types, but each has certain problems:

[0003] The first method is to use pyroelectric infrared sensors to detect whether people have entered restricted areas or ranges. However, due to the use environment with a lot of coal dust and the focusing characteristics of infrared rays, there are problems such as low sensitivity, large detection errors, and susceptibility to interference. In addition, the sensor cannot identify the identity of people, and thus cannot effectively provide accurate feedback of information.

[0004] The second method: using AI cameras to detect whether people have entered restricted areas or ranges. However, due to the poor lighting and large amount of coal dust at the underground mining working face, the camera lens is easily covered by coal dust, resulting in blurred images. The camera cannot detect whether people have entered restricted areas. Moreover, due to the installation angle and the fact that people wear masks, the identity of the people cannot be identified.

[0005] The third method: detecting whether a person has entered a restricted area or range through positioning. However, in actual use, the positioning device has problems such as positioning delay and position offset, and there is no video evidence, which is not conducive to subsequent tracing.

[0006] In summary, real-time monitoring of coal mine working faces needs further optimization and improvement. Summary of the invention

[0007] In view of the problems raised by the above background technology, the purpose of the present invention is to provide a dust removal camera device based on UWB positioning, AI analysis and control output.

[0008] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0009] A dust removal camera device based on UWB positioning, AI analysis and control output, comprising a box body, the box body shell is equipped with various connection ports, a core board is installed inside the box body, a UWB positioning board is installed on the lower side of the core board, an interface board is installed on the lower side of the UWB positioning board, an optical fiber transceiver is installed on the lower side of the interface board, a plurality of support rods are installed between the core board, the UWB positioning board, the interface board and the optical fiber transceiver, the box body is equipped with two 485 interfaces on the side of the interface board, the box body is equipped with an imaging module on the other side of the interface board, and the box body is equipped with a dust removal device on the working end of the imaging module;

[0010] The connection port, UWB positioning board, interface board and fiber optic transceiver, 485 interface, imaging module and dust removal device are all connected to the core board signal and controlled by the core board; the core board signal is connected to the core switch, and the core switch is connected to the background monitoring computer and server signal.

[0011] It is further defined that the connection ports include but are not limited to network cable interface, audio interface, video interface, power interface, alarm interface, MIPI interface, DVP interface, CSI interface and USB interface. Such a design ensures data information and transmission, docking and device connection.

[0012] It is further defined that the box body is equipped with a signal amplifier electrically connected to the core board. Such a design improves the signal strength, increases the communication capability of the system, extends the transmission distance, and enables the device to meet a wider range of uses.

[0013] It is further defined that the box body is equipped with an audible and visual alarm electrically connected to the core board. Such a design is conducive to sending out a strong audible and visual alarm signal in an emergency situation to alert on-site personnel to pay attention and take corresponding actions.

[0014] It is further defined that a layer of nano-level material is applied to the surface of the lens sheet of the imaging module. With such a design, the nano-material can significantly improve the performance of the imaging module due to its unique physical and chemical properties, such as large specific surface area and high chemical reactivity. When applied to the surface of the imaging module, these properties help to optimize the imaging effect.

[0015] It is further specified that the core board has a built-in RV computing chip. Such a design realizes AI analysis, obtains the position of people in the picture based on the target detection algorithm, judges the overlap between people and the ROI area according to the preset ROI area, judges whether the people are in the area, and generates corresponding alarm information.

[0016] It is further defined that the dust removal device is a windshield wiper device. Such a design is simple and easy to install and has an obvious dust removal effect when used.

[0017] It is further defined that the UWB positioning board adopts the TOF signal flight time algorithm to read the card number and distance of the UWB personnel card. With this design, the TOF technology accurately calculates the distance of the object by measuring the flight time of the light pulse, with centimeter-level measurement accuracy, and is suitable for scenes that require precise distance information. The TOF camera can quickly obtain the depth information of the entire scene. The TOF sensor is not affected by ambient light and can work under various lighting conditions, ensuring the stability and accuracy of the measurement. The TOF sensor can be integrated into small devices, improving the intelligence and automation level of the equipment.

[0018] It is further defined that the core board has built-in positioning board protocol and positioning card database. With such a design, the positioning board protocol plays a key role in the wireless communication system, ensuring the signal transmission and analysis between the positioning board and the satellite or base station, thereby achieving precise positioning. The positioning card database is used to store and manage the location information collected by the positioning card, ensuring the accuracy and real-time nature of the data, supporting personnel identification, real-time positioning, trajectory playback, emergency assistance, data recording and analysis, attendance management and other functions to meet the needs of different scenarios. The positioning board protocol ensures accurate transmission and analysis of the signal, and the positioning card database is responsible for data storage, management and the realization of diversified functions, jointly providing stable and reliable services for the positioning system.

[0019] The beneficial effects of the present invention are as follows:

[0020] The present invention uses a variety of technologies to make comprehensive judgments and continuously monitor whether people enter restricted areas and ranges. When a person enters a restricted area or range, the camera reads the positioning card number through the positioning board, detects violations through the core board, and comprehensively judges the identity of the violator. The sound and light alarm can be linked, and the equipment can be controlled to shut down. The accuracy of the alarm is greatly improved, accidents are avoided, and the probability of equipment shutdown due to false alarms is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
