AI Technical Summary

Technical Problem

Existing manhole operation safety monitoring devices lack the functions of real-time detection, analysis, display, alarm, and remote uploading of comprehensive data on methane concentration, ammonia nitrogen concentration, oxygen concentration, hydrogen sulfide concentration, and liquid level parameters, and cannot achieve integrated multi-parameter monitoring and wireless data transmission.

Method used

A manhole operation safety monitoring device was designed, which integrates a methane sensor module, an ammonia nitrogen sensor module, an oxygen sensor module, a hydrogen sulfide sensor module, a liquid level sensor module, a wireless transmission module, a positioning module, an alarm module, and a display module. It adopts 4G or 5G wireless transmission technology to realize real-time monitoring of the concentration of multiple gases and liquid levels, and transmits the data wirelessly to mobile phones and computers for remote management.

Benefits of technology

It enables real-time monitoring, analysis, display, and alarm of multiple parameters of the manhole environment, preventing unauthorized operations by on-site personnel, ensuring their safety, and providing decision support through a remote management platform, thereby extending the device's operating time.
