INTELLIGENT SAFETY ALARM SYSTEM FOR CONSTRUCTION OPERATION IN STEELMAKING WORKSHOP AND ALARM METHOD THEREOF

摘要

The present invention relates to the technical field of safety production electronic information. Disclosed are an intelligent safety alarm system for construction operation in a steelmaking workshop and an alarm method thereof. The present invention comprises an alarm main control unit and two distance measurement sensing units. The alarm main control unit is installed in a construction operation area. The two distance measurement sensing units are installed near a feeding area and a discharging area, respectively. The alarm main control unit and the distance measurement sensing units are all designed in a portable manner and provided with high-temperature-resistant outer covers, thereby avoiding damage to equipment due to molten steel splashing, and can be flexibly installed according to construction requirements without modification to existing equipment or influence on the production process. Alarm information is transmitted by means of wireless communication, and an alarm is issued in various alarm modes by means of the alarm main control unit, thus effective alarming is performed and manpower consumption is reduced. Moreover, the construction operation area is provided with an image acquisition device bound to the alarm main control unit, so that if people are not evacuated in time in the construction operation area, a second alarm is issued when necessary, thereby ensuring that all the people can be evacuated.
