DEVICES AND METHODS FOR QUANTITATIVELY TESTING FATIGUE LEVELS OF CONSTRUCTION WORKERS

摘要

A construction worker fatigue testing device is disclosed. The devicecomprises alaser sensing component for detecting a construction worker's steppingposition, adanger zone, a safety zone, and a control device which is in communicativeconnection with the laser sensing component, wherein when the laser sensingcomponent detects that the worker is completely stepping on the danger zone,thelaser sensing component sends a first signal to the control device, and thecontroldevice receives the first signal and judges that the worker has made a mistakeI, andwherein when the laser sensing component detects that the worker is steppingonthe junction between the danger zone and the safety zone, the laser sensingcomponent sends a second signal to the control device, and the control devicereceives the second signal and judges that the worker has made a mistake II,andwherein when the laser sensing component detects that the worker is completelystepping on the safety zone, the laser sensing component sends a third signalto thecontrol device, and the control device receives the third signal and judgesthat theworker has made no mistake.
