AWS
AWS (Auto Wake-up Switch) is the unit that enables tanker automation systems to send data to the center, especially when the tanker is not working and the system is turned off. Depending on the time schedule, AWS provides the tanker automation system to be fed from the vehicle battery, during the periods when the tanker is not working and its contact is closed, receives confirmation that the tanker supply data is sent to the center, and then ensures that the system shuts down. In this way, both central uninterrupted data transmission is ensured and the batteries of the tankers are not exhausted.
