THE MOVABLE CONTROL SYSTEM FOR THE CONSTRUCTION SITE

摘要

A movable control system at a construction site is provided to sense an operator approaching a dangerous area of a construction site, alarm the danger for the operator not to approach anymore, and enable a wounded operator to operate an emergency call unit to ask for help immediately. A movable control system at a construction site comprises the following units. A sensor detecting unit includes a human body infrared ray sensor unit(111) and a ultrasonic wave perceiving sensor unit(112). A controller(120) electrically connected to the sensor detecting unit generates a warning sound according to access of an operator and transmits access status of the operator to a central computer. A danger warning unit is composed of a sound record unit(131) recording a proper warning sound and a sound output unit(132) generating a recorded sound. A mobile detector(100) includes a battery or a power supply unit(150). A central computer is connected to the mobile detector through a wireless network.
