Valve Remote Fault Diagnosis System Based on Internet of Things Technology

Abstract

The invention discloses a valve remote fault diagnosis system based on the IOT (Internet of Things) technology. An intelligent valve terminal communicates with main control equipment through a zigbee network, and the main control equipment communicates with a remote monitoring platform through the Internet. The intelligent valve terminal comprises a sensor module, a data collection module for collecting a sensor signal, and a zigbee module for sending the signal. The main control equipment comprises a zigbee module for receiving a zigbee network signal, and a GPRS module for transmitting the signal. The remote monitoring platform comprises a database module, a real-time display module for the real-time display of the data, and an alarm module. The sensor module comprises a pressure transmitter, a valve rod position sensor, a temperature transmitter, a VOCs sensor, and a valve rod torque sensor. The system is low in cost, is high in practicality, and is high in efficiency.

Description

technical field [0001] The invention relates to a valve remote fault diagnosis system based on Internet of Things technology. Background technique [0002] Industrial valves play the functions of controlling fluid on-off, adjusting fluid pressure and changing the direction of fluid flow in the pipeline system. Under some harsh working conditions, the medium flowing through the valve is usually high temperature, high pressure, high radiation, poisonous and flammable, and the safety production problems caused by the failure of such valves have become increasingly prominent. Therefore, it is necessary to monitor and diagnose the state of high-critical valves in the pipeline, so as to know the health information of the valves in time, so as to take effective measures to avoid safety accidents caused by valve failures. [0003] Existing valve fault diagnosis requires operators to measure the operating parameters of the valve through equipment at the job site. Because the valves...

AI Technical Summary

Problems solved by technology

Due to the need to test the valves one by one, the work efficiency is relatively low; on the other hand, because the operators operate on site, they face the risk of leakage of various media on site, and the safety of the operation cannot be guaranteed.

When using the field bus to monitor and diagnose the valve, the field wiring is difficult, the failure rate is high, and the stability is poor
