Monitoring and Measuring System of Steel Rope Applied to Mine Hoist Base on GSM Network

In the recent years,the cage dropping accidences of the mine hoist occurred sometimes.The tensile failure of the steel rope was the main cause and therefore the pulling force of the steel rope detected could judge the operation status of the hoister.Base on the circumstances,a monitoring and measuring system was designed.The monitoring and measuring system could on-line monitor and measure the pulling force of the steel rope and could display the pulling force.When the pulling value was over the normal value,the waning message would be sent the worker's phone with the GSM network and thus the risk could be avoided.With the field measuring and test conducted in Ezhuang Mine of Lanwu City,the system was feasible.
