Distributed wireless monitoring device and system for steam heat-supply network steam trap as well as working method

Abstract

The invention relates to a distributed wireless monitoring device and system for a steam heat-supply network steam trap as well as a working method. The distributed wireless monitoring device comprises a pressure sensor and a processor module, wherein the pressure sensor is mounted a guide pipeline of the steam trap and used for monitoring a pressure value in the guide pipeline when the steam trap normally discharges condensate water or the steam trap is in failure; the processor module is connected with the pressure sensor and a wireless transmission module, and used for receiving normal water drainage amount scope information of a pipeline, where the steam trap is positioned, from a monitoring center server, analyzing the waveform of the pressure valve in the guide pipeline of the steam trap, identifying a normal water drainage action message and failure characteristic information to judge whether the steam trap is in corresponding failure or not, sending the failure alarm information to the monitoring center server in real time, meanwhile, summarizing the pressure valves in the guide pipeline of the steam trap at different times and sending the pressure valve in the guide pipeline of the steam trap to the monitoring center server. By adopting the distributed wireless monitoring device, whether the steam trap of the steam heat-supply network is in corresponding failure or not can be accurately judged and the service life of the steam trap is monitored.

Description

technical field [0001] The invention belongs to the field of the Internet of Things, and relates to the monitoring of the drainage action of a large number of steam traps in the steam heating pipe network and the health status and service life of the equipment, and in particular to a device for monitoring the leakage of steam traps in the steam heating pipe network. systems and methods. Background technique [0002] At present, steam traps are widely used in my country's industrial steam heating pipe network to discharge condensed water in the pipeline. Most of the existing steam traps are of mechanical structure, which cannot be monitored online. Usually, only manual regular inspections are used to judge their health status, so that steam trap failures such as steam leakage cannot be discovered in time, resulting in failure of the heating system. Increased network loss, and may bring security risks. In addition, due to the large number of steam traps installed in the stea...

AI Technical Summary

Problems solved by technology

The VPK40 detector is only a single-node detection, and it is not convenient to detect the steam traps installed in high-altitude overhead pipes or underground pipelines, and cannot realize continuous online monitoring

In addition, the existing steam trap detectors can only provide an indication of the complete failure of the steam trap, and cannot provide early warning of the steam trap failure in the early stage of the steam trap failure, nor can it make statistics on the operation times and life loss of the steam trap
