MONITORING SYSTEM ON BRAKE CLEARANCE OF MAIN SHAFT HOIST IN HONGYANG NO.2 COAL MINE BASED ON LASER DETECTION TECHNOLOGY

Monitoring system on brake clearance of main shaft hoist in Hongyang No.2 Coal Mine based on laser detection technology

This paper introduces the technical transformation and system realization of the hoister gap monitoring and protection device in Hongyang No.2 Coal Mine.Through the high-precision laser Menu Boards displacement sensor, we detected displacement signals, such as brake clearance, brake wear value, spring fatigue and brake disc deflection, to convert i

Modulation of protein fermentation does not affect fecal water toxicity: a randomized cross-over study in healthy subjects.

Protein fermentation results in production of metabolites such as ammonia, amines and indolic, phenolic and sulfur-containing compounds.In vitro studies suggest that these metabolites might be toxic.However, human and animal studies do not consistently support these findings.We modified protein fermentation in healthy subjects to assess the effects
