Abstract
The utility model is suitable for the field of automotive electronic technology, and provides a DTU (data transfer unit) with multiple SIM card data terminals based on mobile communication. The DTU comprises a central processor, a mobile module, an intelligent card switch, a power module, and an intelligent card module. The central processor is connected with the mobile terminal. The output end of the central processor is connected with the intelligent card switch which is connected with the intelligent card module. The power module is electrically connected with the central processor, the mobile module, the intelligent card switch, and the intelligent card module. The intelligent card module 50 comprises a first intelligent card interface and a second intelligent card interface. Through single-module double-card operation, the transmission of mobile data is effectively solved. The reliability link backup of the same type under the condition of the existing of a plurality of service providers guarantees the stability and reliability of a data channel, thereby more effectively removing the faults of link arrearage and relative abnormality on the quality of a mobile network. The DTU is simple in structure, is easy to operate, and reduces the cost.
