Wireless sensor network (WSN) integrated with sensors, embedded computing, networking and wireless communications technology, is considered one of the technologies that exerts an profound influence in the21st century. Large-scale intensive wireless sensor networks characteristic large, network size, multi-node deployment-intensive, mass data, and self-organization.It used to prone to imbalance in the local energy consumption, that resulted in network structure rupture Eventually the network life cycle is over prematurely. In this paper, a large-scale battery charge and discharge control system is an application background of energy consumption balance issues of large-scale intensive sensor networks.In this paper, we focused energy issues for large-scale intensive sensor networks. The main tasks are:(1) First, based on the battery charge and discharge background and needs, we designed large-scale electrical storage charge and discharge monitoring system.(2) For quantitative analysis of energy model of sensor networks, we can observed energy hole phenomenon around the Sink node in sensor networks, the problem caused of many-to-one communication mechanism of sensor networks, then we proved that the energy hole problem is inevitable.(3) the network topology and the control mechanism is the basis of the sensor network, Research on network topology control for large-scale intensive sensor network load balancing issues have great significance.For large-scale sensor network clustering structure topology control algorithm, we proposed a load balancing cluster topology control algorithm (LBH), Taked insiderable of the average remaining energy and residual energy in the cluster stage, net generated cluster head with energy sufficient. For maintenance stage, it adaptive maintenance wrap a cluster of nodes in the cluster, making the network as a whole and balanced.(4) Combined with the previously proposed topology control algorithms, in accordance with the requirements of characteristics of large-scale intensive network energy consumption requirements, we proposed a power control based on load balanced adaptive routing algorithm (PC-LBA). It combined with the optimal transmission power and node residual energy parameters to select the optimal node in the routing table, making the entire network load balancing.(5) Finally, we took experiment on the battery charge and discharge monitoring system to test the performance of the algorithm in the article. The experimental results show that the proposed algorithm is effective to alleviate the imbalance of the energy consumption of the network. The main subject of large-scale intensive sensor network is load balancing issues.According to network common characteristics, energy consumption of a balanced topology control and network layer routing,for the purpose of proposed energy consumption of a balanced topology control algorithm based on strategies of power control, adaptive routing algorithm achieved effectively the balance of energy consumption of sensor networks extend the life cycle. Finally, in industrial applications, with the value of certain engineering applications.
