Garment factories are labor-intensive, and workers mainly operate their machines. In these factories, the efficiency of energy usage almost depends on workers' behavior. Besides, factory customers require reliable energy efficiency data to meet carbon emission standards. Therefore, factories need an energy management solution in industry to effectively manage primary energies such as electricity, water, compressed air, fuel to overcome the following difficulties:
Sensors are available everywhere at factories, and they are present in all systems for measuring parameters such as steam pressure, pipeline temperatures, water tank level. Although there are different types and brands, the sensors usually have an output of analog signal 4-20mA and are connected to the center by a signal wire. Therefore, if the factory adopts a wireless sensor network, it will help to eliminate the difficulties of a wired network as follows:
The main cost in ferry operation is fuel. With scattered ferry terminals, the management department at the headquarter faces many challenges in managing ferry operations, especially monitoring and managing fuel in storage and daily tanks on the ferry. In addition, effective coordination of fuel supply for scattered ferries is a big concern . Ferry operation companies demand a centralized fuel management system to solve the following fuel management difficulties:
As the competition among businesses becomes more fierce than ever, especially product cost competition, manufacturers have to optimize their production costs to stay ahead of their competitors and maintain a reasonable profit. Among solutions for production cost reduction, deploying factory energy management systems for production optimization is favored by most factories. However, there are a few problems in applying a traditional solution to energy management:
