IOT card with SmartGen cloud monitoring communication module can realize genset (with serial communication interface) access to the Internet. After the module logs into the cloud server, the cloud server will transmit the corresponding genset controller communication protocol to the module. Cloud monitoring module can get the data information of genset through RS485 interface, USB interface, LINK interface, CAN interface or RS232 interface, and transmit the data information to the corresponding cloud server via 4G wireless network, so that user can monitor genset running status and query its running records in real time through mobile phone APP (IOS or Android system), computer and other terminal equipment.
