IoT Globiots energy management solution helps us to find out electrical energy waste especially at night time and to design relevant methods to save 5% electrical energy without further investment. Nguyen Tri Dung - Factory technical manager
Customer challenges
Esquel Hoa Binh, a factory of Esquel Group, specializes in clothing manufacturing for famous brands, such as Nike, Tommy Hilfiger, Hugo Boss, Brooks Brother, and Abercrombie & Fitch. The factory copies with following challenges in energy management:
Collected electrical data is NOT updated, missing, and has low reliability
The eThe Energy manager doubts electrical energy waste, especially at night and non-working time
Labour is wasted collecting daily electrical energy data and making daily Excel reports manually
Factory customers do NOT know whether the factory uses electrical energy effectively
EMS IoT Globiots solutions
Daviteq provides an energy management system for the whole factory to monitor 20 power meters (model Selec EM368) which have been available since Oct 2016. The system transmits the data of the power meter to Daviteq’s IoT Globiots cloud platform to monitor through laptop, desktop and tablet.
A 3G iConnector gateway connects all 20 Selec’s power meters through port RS485, Modbus RTU protocol. The iConnector collects data from power meters and transmits them to the IoT Globiots cloud server through GPRS/ 3G cellular network. Data is stored and analyzed in the cloud server. Vizuo, a web application software, views dashboard, event, alarm and energy reports to help effectively manage the factory’s electric power. Energy reports, event and alarm notifications are also sent to registered emails.
Two simple steps implement system deployment. Firstly, the customer replaces an RS485/ RS232 converter with a 3G iConnector and the iConnector is connected to power meters in the form of bridge wiring by a 2-core twisted shielded cable. Secondly, the system, parameters, alarm, event, software interface and user are configured remotely through a web interface. After configuration, users could log in to the Vizuo application software using a web browser (Google Chrome, Mozilla Firefox…) with provided user name and password to manage electrical energy.
Solution results
Save 5% on electrical energy
The solution assists the factory in identifying energy waste, especially at night time and non-working time as operators forget to turn off lights, production machines and other equipment
Cut labour by 40 hours/ month
The automatic monitoring system completely replaces humans in daily energy data collection and in making daily, weekly and monthly energy reports
Increase machine lifetime
Timely identifying and handling problems of energy quality and those of abnormal machine’s low load help increase machine lifetime and reduce fire risks
Promote company brand name
The system complies with the factory customer’s energy management requirement in terms of energy data transparency and promotes the factory as a model of energy management
