Abstract Internet of Things Acoustic Emission (IOT AE) was developed and introduced in hardware, software and network structure. IOT AE transmits the data and analysis results to the network server through the Internet/intranet. The analysis results can go to the end user’s smart phones and PCs as alarm info. Users don’t need the acoustic emission technicians to operate IOT AE. So IOT AE can be used as remote long-term unattended monitoring and automatic alarm system. Compared with traditional acoustic emission instrument which needs to process the data manually to get the detection and monitoring results, IOT AE control the data acquisition and data analysis by embedded software automatically. Besides the long-term cycle of self-learning correction of artificial intelligence based on big data on the server makes the system have the ability of self-learning, self-
improvement and continuous improvement of performance.
This paper introduces the IOT AE systems developed and discusses the application of IOT AE technology of monitoring and
alarming for valve leakage, wire rope breakage and tool wear, etc..

1 IOT AE System Introduction
1.1 Architecture of IOT AE monitoring and alarm system
IOT AE system consist of AE sensor, AE data acquisition and data analysis module (AE module), internet/intranet communication module, server/smart phone/PC. Firstly, the AE sensor installed on the monitoring object (valve pipeline, bridge steel cable broken wire, CNC machine tool, etc.) collects signals, and converts the tiny mechanical vibration signals into voltage signals. Then the AE module processes the voltage signal and outputs the results (alarm info, AE waveform and AE hit parameters). The outputs of the AE module are transmitted to the server/smart phone/PC by internet/intranet communication module.
The system architecture is shown in Figure 1
