UWB System and method of safety accident control using UWB based real time location

摘要

The present invention relates to an accident control system using UWB-based real-time positioning. An objective of the present invention is to provide a system which uses a real-time positioning system to identify a current location of a worker in a work place in real time, and allows automation equipment in a zone linked for safety of the worker to stop the system and provide an alarm function when the worker approaches the zone (access restriction zone) previously stored in a map. To achieve the objective, the accident control system using UWB-based real-time positioning comprises: a UWB tag worn by a worker; a plurality of UWB anchors installed around a process line where an industrial robot, a conveyor belt, and a motor are installed to receive a location of the worker from the UWB tag and sense a temperature, humidity, illumination, and a frequency of the process line; an access point to receive the location of the worker and the temperature, the humidity, the illumination, and the frequency of the process line from the plurality of UWB anchors; a server to receive and store the location of the worker and the temperature, the humidity, the illumination, and the frequency of the process line from the access point, and determine whether the location of the worker is within a preset access restriction zone; and a PLC box to control to stop operations of the industrial robot, the conveyor belt, and the motor in the process line if proximity information indicating that the location of the worker is within the access restriction zone is received from the server via the access point.
