Alarm device for electric shock danger in switch-board using complex sensors

When the danger area and protected from the switchgear is installed in the required areas a person approaches within the set distance generates a critical alarm, and one that can be used as the administrator (inspectors, workers, etc.) video to identify accident causes the future to keep a record of data the number, distribution board electrical shock hazard alarm system using the composite sensor is disclosed. The disclosed composite sensor, the number of switchgear Electrical Hazard alarm systems are used, and detects the approach distance of the object, a sensor unit for detecting a movement of the object, and outputs the object detection information and the motion information; And calculates the access distance and the movement information determining the alarm operation status based on, and can, based on the object detection information at the time of alarm operation, the switchboard shock hazard alarm system and the object, differentiated according to the above calculation approach distance performing the alarm to be a main control unit to recognize that the risk of electric shock. Switchgear, electric shock, multiple sensors, alarm
