Embodiment Construction
[0020] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.
[0021] The application provides a deep mine wireless power transmission device, which can satisfy the power supply of deep mine monitoring nodes. Among the underground monitoring nodes, most of the original nodes are changed to nodes with wireless energy transmission and reception functions; a small number of nodes are still powered by wires (called source nodes), which add wireless energy transmission functions as energy sources for other ordinary nodes. The electric energy can be transmitted to the whole monitoring node network by wireless transmission through the wired input source node (such as on the mine car) or the underground charging input source nod...

The invention discloses a deep mine wireless power transmission device which is characterized in that the device comprises a source node and common nodes, the source node is powered by a cable or mine charging and is divided into a static source node and a dynamic source node, the static source node is arranged at an entrance to a branch roadway from a main roadway, the dynamic source node is a mobile node in mobile equipment, is powered by a mine lamp storage battery or equipment power supply and provides wireless power transmission for other common nodes. The common nodes can receive the wireless power information emitted by the source node and can wirelessly transmit information mutually. According to the deep mine wireless power transmission device, the requirement of long distance wired power supply limit in a severe environment and accident risk are reduced, cables are reduced, the roadway space is improved, the monitoring node layout is simple, and the device still can provide monitoring, communication and other services for downhole operation or rescue especially in the conditions of power failure in an accident and wired power supply failure.
Description
technical field [0001] The application belongs to the technical field of wireless communication, and in particular relates to a deep mine wireless power transmission device. Background technique [0002] In the harsh environment of deep underground mines, environmental factors such as high temperature, high humidity, and poor air quality will accelerate the aging of wired power supply lines, and the long cable lines and many line contacts make the power supply reliability poor, and the contacts are prone to sparks, and even cause Explosion major accident. In the event of an accident, the wired power supply cable is easily broken and damaged, and there is no power supply and transmission interruption after the break point, resulting in failure of monitoring. In order to ensure the life safety of underground operators, the above problems need to be solved, and it is necessary to develop a wireless power transmission device capable of storing energy.
