OPERATION SAFETY MONITORING SYSTEM IN CIVIL ENGINEERING WORK SITE

摘要

PROBLEM TO BE SOLVED: To secure security of a civil engineering work using a hydraulic excavator and provide an operation safety monitoring system that renders an operation monitoring to be implemented objectively as well as concretely.;SOLUTION: By manufacturing an arrow mark 30 displayed under a display unit 23 a value setting of a dangerous scope and a specified setting of workers have been previously made. After such setting has been finished, if a switch 31 displayed below is pressed for decision, display 32 of dangerous (scope) area and the number for each operator 1 to 4 is displayed. The CPU determines and monitors, whether or not they are in the dangerous area from operators' communications conditions. If it is judged that they enter the dangerous area (in this case, an operator 1), to the operator 1, an alarm is generated to his alarming measures including a buzzer. At the same time, any motion of the backhoe is braked.;COPYRIGHT: (C)2002,JPO
