Description

Technical Field

[0001] This utility model relates to the field of video surveillance technology, and in particular to a high-speed image processing camera for mining, with applications in underground coal mines. Background Technology

[0002] In coal mine safety production, video surveillance systems are crucial for ground dispatching and underground operation command. However, existing underground cameras in coal mines have the following main shortcomings: (1) The underground environment is complex and the tunnels are crisscrossed. Laying optical cables / electric cables requires a lot of engineering work, including drilling, anchoring, threading, sealing, etc. The wiring is complicated, time-consuming and labor-intensive, and the material and labor costs are extremely high. (2) Once the position of the camera is fixed, it is difficult to move flexibly as the mining face advances, resulting in poor flexibility; and if the working face moves forward by several hundred meters, it is necessary to re-lay cables of the same length, which involves a large amount of work and affects the production progress. (3) Currently, the cameras deployed underground generally only support the normal frame rate mode. When shooting high-speed moving objects, ordinary cameras suffer from dynamic blur and loss of details, and their information capture capability is insufficient. Furthermore, the complex factors such as insufficient lighting, coal dust, and high humidity in the underground environment can easily lead to problems such as blurred images, insufficient brightness, or noise interference, which directly affect the clarity and reliability of the monitoring images, thereby restricting the accuracy and timeliness of dispatch and command, and making it difficult to meet the needs of high dynamic scenarios such as main coal flow monitoring and violation capture. (4) After massive amounts of video data are transmitted to the ground computer room, manual monitoring or post-event review is required. It is impossible to detect abnormal situations in real time (such as foreign objects on the conveyor belt, large pieces of coal on the conveyor belt, running red lights underground, etc.). The potential value of the data is greatly wasted, and the data value utilization rate is low. (5) The underground environment is harsh, and cables are easily damaged by squeezing, breaking, moisture corrosion, rodent bites, etc. Any line fault may cause the entire monitoring point or even multiple points on a section of the line to malfunction, and the fault point is difficult to find and repair. When a fault occurs, maintenance personnel need to go down into the well to the specific location for investigation and repair, which is not only slow to respond, but also affects normal underground operations; (6) The system architecture is outdated and cannot be upgraded with software to obtain new intelligent analysis functions. It is difficult to adapt to the requirements of future intelligent development of coal mines and has poor investment protection. Utility Model Content
