Aiming at the problems of high economic demand, easy to be interfered by the outside and high power loss in traditional communication technology, this paper designs a set of very suitable solutions, which is based on Lora ad hoc network wireless transmission technology and combined with a / D power consumption information acquisition system to form a set of good solutions. Lora spread spectrum technology and low power consumption technology are used to solve the problems of long-distance wireless communication vulnerable to interference and high power loss, and a / D power consumption information acquisition system is used to solve the problem of low accuracy of traditional acquisition methods in big data environment. The simulation results show that the long-distance communication and low power consumption of Lora wireless transmission technology can be realized, and the accuracy rate of a / D power consumption information acquisition system is up to 3% higher than that of Web automatic acquisition program in big data environment.
