Review on Key Technologies of Wireless Monitoring of Pump Group Based on Internet of Things

In this paper, Internet of Things (IoT) technology is applied to wireless monitoring field of pumps. The structure of wireless sensor network nodes in the perception layer of the IoT, as well as the division and function of each part of the wireless monitoring system in the process of signal acquisition and transmission are analyzed. The characteristics of several wireless monitoring technologies and their best applicable working environment are introduced. LoRa wireless communication technology is selected to monitor the pump group, taking LoRa technology as an example, the role and technical advantages of IoT in the whole wireless monitoring system are elaborated. At the same time, some problems of wireless monitoring technology are pointed out.
