With the continuous progress of science and technology and development,things have been gradually applied to many areas.Due to the particularity and complexity of the operating environment and operation mode of the coal mine,the power supply of the coal mine underground sensing layer is mostly battery-powered.Therefore,how to maximize the energy of the sensing layer node to improve the life cycle of the sensing layer network becomes the current research of the important issues.In order to be able to extend the life cycle of the sensing layer network as much as possible,this paper makes the following research:In this paper,the design principle of the controllable topology control algorithm and the classical topology control algorithm are briefly introduced.In order to meet the shortcomings of the existing connected dominating set algorithm in sensing the energy consumption and network life cycle of the node,in order to meet the network life cycle,the proposed topology control algorithm based on connected dominating set is proposed.Based on the connected domination set,the genetic algorithm is used for further optimization.The simulation results show that the algorithm proposed in this paper can improve the life cycle of the entire perceptual layer network by saving the energy consumption of the perceptual layer network.According to the proposed algorithm model,this paper designs the sensor nodes and gateway nodes from the hardware and software respectively.In terms of hardware,the minimum system of the sensing node,the power module,the sensor module,the wireless transceiver module and the gateway node are designed,and the communication between the sensing node and the gateway node is realized by serial communication.On the software side,the software design of the sensing node and the gateway node is carried out by using the modular design,and the communication between the sensing node and the gateway node is guaranteed.According to the design of hardware and software,it is verified that the perceptual layer nodes of the underground use the feasibility and superiority of the topology control algorithm of the Internet of Things based on the connected domination set in the network life cycle.
