Generally, workers in the traditional energy industry (e.g. coal mining, iron and steel production) face work risks and hazards on daily basis. Equipment and machineries are susceptible to malfunction if not monitored properly. Therefore, it is of paramount importance for companies to make sure that their employees are safe in their premises, and all equipment are well maintained. By utilizing digital intelligence, Dahua has established a robust solution that can actively safeguard personnel and constantly monitor plant equipment to ensure a safe and orderly production workplace.

Smart Detection of Safety Work Uniform & Gears

Proper wearing of safety gears (e.g. helmet, mask) and work uniform in production areas is detected by the system. An alarm will be triggered and notification will be sent to the security staff when someone violates the rules.

· Steel Factory: The solution detects wearing of fire mask and fire suit in critical areas with high temperature. It also provides safety detection of special tools and gas detectors in confined spaces.

· Power Plant: The solution offers an intelligent closed-loop management that covers real-time monitoring, violation detection, capturing, reporting, and handling of an event. It strengthens early warning for safety risks to ensure the safety of each personnel.

· Optical Cable Workshop: The system sends early warning in real-time for improper wearing of work uniform, dangerous operation of cable reels, and unsafe operation distance, protecting production line operators and avoiding accidents.

Monitoring of Production Equipment

In the traditional heavy industry, equipment safety is imperative to guarantee an efficient and safe production in the factory. Through digital transformation, intelligent equipment and solutions can simultaneously monitor the safety of production equipment to ensure a safe and orderly operation.

· Coal Mine: The solution enables visual supervision of the whole process in the main logistics system. At the same time, it can intelligently analyze the belt operation status and coal flow status in the plant. It sends early warning in case of any belt malfunction such as deviation, sudden stop, coal overloading, abnormal items, etc., which helps security personnel to quickly locate the risk and act in time.

· Power Substation: Various HD cameras, patrol robots, sonar, and other intelligent devices are used to collect audio and video data on the site. Intelligent recognition and early warning of equipment status are generated through AI-based visual, auditory and thermal imaging temperature monitoring technologies. The integration and linkage of primary and secondary systems realizes unmanned three-dimensional patrol as well as remote operation of equipment and facilities. It provides basis for decision making, enables convenient equipment operation and maintenance, accelerates emergency respond, and ensures safety of each equipment.

Plant Management & Production Environment Safety

The solution utilizes digital technologies to collect information about production scenarios, personnel, vehicles and objects in order to achieve overall control in terms of real-time monitoring, intelligent early warning, automatic system control, and more.

· Warehouse: An intelligent device senses the environment temperature in real-time, and sends an alarm when smoke or abnormal temperature is detected. The system displays the alarm location on the platform to aid responders, which helps prevent fire at an early stage.

· Chemical Enterprise: The solution offers an AR panoramic view for hazardous chemical factories through video splicing technology. Also, it provides complete global control of equipment zones at high points, achieves dynamic online "electronic map", and prevents people and vehicles from entering restricted areas through intelligent Tripwire technology. Using AR tags and IoT technology, videos and IoT data tags of the scene can be overlaid and displayed on the screen, achieving image-to-image detailed viewing, improving management efficiency, and protecting the workplace safety of chemical plants.

Safety is the eternal theme of production; production must be safe, and safety promotes production. With the help of digital intelligence, Dahua has delved into various scenarios in the energy, manufacturing and other industries in order to create a more efficient personnel operation management system, a more intelligent equipment operation and maintenance system, and a more sustainable and safer production workplace for everyone.
