Requirements for the installation position of coal mine cameras
The installation location of the coal mine camera has the following requirements: 1. The installation location of the mine end is the main and auxiliary wells of the coal mine, the wind well, the vehicle entrance and exit, the dispatching room and other key locations. 2. The underground of the coal mine is a special place, and its installation location should meet the explosion-proof requirements. It needs to avoid the impact of the release source and the heat, water and vibration of the process pipeline. 3. Different areas in the underground have different requirements for the camera. For example, in scenes with large dust such as coal mining face, excavation face, belt tunnel transportation, etc., the installation location requirements related to the camera's self-cleaning function shall be considered; when installed on equipment such as hydraulic support and tunneler, the requirements for earthquake resistance and anti-shake shall be considered to ensure stable imaging of the video image; if there is an area with low illumination and clear imaging requirements, the installation location shall meet this requirement; In areas where the strong light suppression function was required, the installation location should be considered to avoid the strong light effects caused by the miners 'headlights and environmental lighting. 4. For the special camera used in the well, considering that the poor sealing would cause internal fog and blurred images, the installation location should be set to solve the problem of poor sealing, such as setting up two chambers. 5. The installation location should take into account the limited transportation equipment and installation conditions underground, so as to facilitate the transportation and installation of lightweight cameras. 6. If you need to support Wifi and 5G communication modes, the installation location must meet the wireless communication requirements. 7. The installation location should avoid damp, dusty, extremely hot, extremely cold, strong electromagnetic radiation and other places. The lens should not be aimed at strong light (such as sunlight, lighting, etc.), so as to avoid the phenomenon of excessive brightness affecting the lifespan of the LCD. Also, it should be confirmed that the power supply voltage is the specified voltage to avoid burning. Read more exciting novels for free
Code for installation location requirements of coal mine cameras
When installing cameras in coal mines, there were the following requirements: 1. Cameras should be installed at key locations such as the main and auxiliary wells, vehicle entrances and exits, and wind wells in the coal mine dispatching room for the implementation plan of the coal mine electronic seal construction. 2. Cameras were installed at key locations such as the main and auxiliary wells of the coal mine, vehicle entrances and exits, wind wells, and dispatching rooms to realize the monitoring of the coal mine's production and operation status. 3. All the underground video equipment of the production mine (including the area within 50 meters of the upper well head) shall be explosion-proof and adopt high-definition equipment. The well head lifting machine room shall be equipped with video monitoring display terminal, which is used to display the video monitoring images of the well head signal room, well head, middle section horse head gate (switching yard) and other places. The dispatching room (monitoring room) shall be equipped with the host computer and display terminal of the video monitoring system. 4. 1 - 4 sets of high-level videos covering the whole plant should be installed on the ground. In addition, video monitoring points should be installed in the main ventilation room, the air pressure fan room, the ground transformer station, the auxiliary shaft yard, the injection station, the ground permanent gas extraction pumping station, the pit wood yard, the machine repair workshop, the entrance and exit of the coal yard, and other places where people work. The unloading part of the main lifting well, the lifting machine room, the loading chamber, the signal room of the auxiliary lifting well, the lifting machine room, the upper and lower wells, the middle horsehead door and the switching yard shall also be installed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Requirements for installation of coal mine camera system
The following are the requirements for the installation of the coal mine camera system: ** 1. Basic requirements ** 1. ** On-site image monitoring function ** - The ground monitoring center must be able to monitor the images of the well and underground operations at any time. The images must be real-time, clear, and smooth. 2. ** About the camera control function ** - It was possible to control the rotation of the pan tilt camera and the spherical camera, as well as the expansion and contraction of the lens, by controlling the host computer or controlling the keyboard. 3. ** Image display event hard disk record inquiry function related ** - It can be used to check the images of events that happened in the past through the control host computer to facilitate the analysis of events. ** 2. Special requirements (due to the special nature of the coal mine production environment)** 1. ** Explosion-proof features of underground electrical equipment ** - The cameras and other equipment of the underground video system of the coal mine must meet the explosion-proof technical requirements, because there is a dangerous environment that is flammable and explosive underground. At the same time, the lighting conditions in the well were poor and the environment was harsh. There were very strict requirements for the technical parameters such as the working current and power of the video transmission equipment. 2. ** Underground Transmission Method ** - The underground uses a combination of optical fiber digital transmission and wireless transmission. The optical cable had the advantages of large information capacity, no electromagnetic interference, wide frequency band, intrinsic safety, light weight, water and fire resistance, high tension strength, and long-distance transmission without relay. It was suitable for the underground conditions of coal mines in terms of image quality, anti-interference ability, transmission distance, and cost performance. Therefore, flame-resistant optical fiber transmission was usually used to capture the front-end image. However, when some of the monitoring points were not too far away from the control center, other suitable transmission methods could also be used. In addition, for the installation of the camera of the "electronic seal" system in the coal mine, it was necessary to install the camera and the edge intelligent analysis terminal at key locations such as the coal mine wind well, the vehicle entrance and exit, the main and auxiliary wells, and the dispatching room to realize the monitoring and analysis of the personnel entering and leaving the well, the number of people, and the coal mine production and operation status. The use of intelligent video recognition technology to timely discover the abnormal movements of the coal mine and push the alarm information. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is it safe to use coal or mine in the Loutian coal mine?
Open pit coal mines should use mine safety certification. The coal safety certification was applicable to underground coal mines, while the mine safety certification was applicable to other metal or non-metal mines that were not coal mines. The open-pit coal mine belonged to the category of non-coal mines, so the mine safety certification should be used. If you want to know more about the follow-up, click on the link and read it!
