In view of many new problems in the enclosure of large coal yards,such as harsh internal environment,abundant toxic gases,and high safety risks,we design and construct an intelligent management and control system for enclosed coal yard based on the design code and practical engineering conditions.This system fully utilizes laser scanning technology,infrared temperature measurement technology,and modern automatic detection technology,and is mainly composed of laser coal stocktaking system,unattended system,safety monitoring system,equipment monitoring control system,and image-type fire detection and alarm system.By applying this system,temperature,humidity,dust concentration,toxic gas concentration,and visible flames in the enclosed coal yard are continuously monitored in real-time,and these dust suppression equipment and fire fighting equipment are automatically controlled.The system enhances the level of unmanned management and the efficiency of safe operations for large enclosed coal yard.
