Problems solved by technology

For battery-powered nodes, although low-power devices and energy-saving algorithms can be used to improve the working life, the energy of the node is always in a state of decreasing and eventually approaches zero, and the energy must be replenished by replacing the battery or charging
Replacing batteries for a large number of nodes on the one hand is too much work, and there are many resistances in practice; on the other hand, it is more difficult to replace batteries for nodes in certain locations

specific Embodiment

[0051] see Figure 1-5 , the present invention provides a technical solution:

[0052] A controlled and opportunistic hybrid wireless charging method, the specific method of which is:

[0053] There are N wireless rechargeable nodes installed on the side wall of the roadway, and a fixed charging station (Stationary Charger, SC) is deployed at a certain distance in the roadway, and the SC is responsible for charging the mobile charging device (Mobile Charger, MC), see figure 1 , each maintenance worker carries a portable charging device, so a maintenance worker is a chance MC, assuming that MC (unless otherwise specified, MC generally refers to controlled MC or opportunity MC, controlled MC refers to a miner carrying a portable charging device, Opportunity MC refers to the MC in the controlled charging mode) with a charging radius of r ch , the communication radius is r co , and there is r ch ≤r co ; Among them, the chance MC can replenish energy by charging at the SC and ...

Abstract

The invention discloses a controlled and opportunistic hybrid wireless charging method, relates to the related field of coal mines, and aims to realize wireless charging of nodes of a mine internet of things, a certain number of fixed charging stations need to be deployed in a coal mine tunnel, and the fixed charging stations are directly connected with an underground power grid, so that stable electric energy supply is realized. Each fixed charging station needs to be equipped with a plurality of mobile charging devices, and the mobile charging devices charge nodes in the roadway according to a certain scheduling strategy after the fixed charging stations are fully charged. According to the controlled and opportunity hybrid wireless charging method, under the condition that the working efficiency of miners is not affected, the charging performance of mine wireless charging is improved through the charging capacity of the miners carrying the portable charging device.

Description

technical field [0001] The invention relates to the related fields of coal mines, in particular to a controlled and opportunistic hybrid wireless charging method. Background technique [0002] It is very important to grasp the working conditions of coal mine equipment, personnel status and environmental information in real time to improve production efficiency and ensure production safety. Deploy the Mine Internet of Things in the mine, and realize the remote monitoring and predictive maintenance of the equipment through the nodes of the Mine Internet of Things to perceive the operating conditions of the equipment; through the dynamic perception of the mine environment parameters through the Mine Internet of Things nodes, the prediction and early warning of mine disasters can be realized. Significantly reduce disaster losses. [0003] According to whether it can be charged on the ground, the nodes can be divided into two types. One type of node is the sensor carried by the ...
