Description

Technical Field

[0001] The invention relates to the technical field of remote monitoring devices, and in particular to a remote monitoring device for coal mine electromechanical transportation equipment. Background Art

[0002] Remote monitoring can be literally divided into two parts: "monitoring" and "control". "Monitoring" is remote monitoring, which can be divided into two parts: one is the monitoring of the environment, and the other is the monitoring of computer systems and network devices. Remote monitoring mainly refers to obtaining information through the network. "Control" refers to remote control, which refers to the method of operating a remote computer through the network. It not only includes restarting and shutting down the remote computer, but also includes daily settings for the remote computer. For example, the function of remote startup can be realized through the cooperation of hardware. Remote control must combine "monitoring" and "control", so the commonly mentioned remote monitoring generally refers to this kind of remote control. In addition, for network administrators, remote control also includes the control of network equipment. In the process of mining or producing coal, coal mine electromechanical transportation equipment is needed to transport coal, ore and other materials through mechanical equipment and power equipment. These equipment usually work in harsh environments, such as high dust, high temperature and humidity. Therefore, higher requirements are placed on the monitoring and maintenance of the equipment. The traditional manual monitoring method is not only time-consuming and labor-intensive, but also difficult to achieve real-time monitoring and timely maintenance. In order to improve coal mine production efficiency and ensure safe production, it is particularly important to develop a device that can remotely monitor coal mine electromechanical transportation equipment.

[0003] Although the remote monitoring devices currently used have met the needs of remote monitoring to a certain extent, they still have some shortcomings. For example, due to the particularity of the coal mine environment, the monitoring equipment is easily affected by pollutants such as dust and dirt, resulting in blurred monitoring images and affecting the monitoring effect. In addition, existing cleaning devices often require manual intervention and cannot achieve automated cleaning, which increases maintenance costs and workload. Summary of the invention
