The circuit structure is compact. Big dipper/GPRS dual-mode positioning is used. The system is simple in structure and high in positioning precision, when agricultural machinery engine data is collected, the main control module can adopt a receiving feedback mechanism with a background server during data transmission, if feedback information cannot be received, the data can be temporarily stored, and the data can be transmitted again after the feedback mechanism is received, so that the integrity and reliability of data transmission are guaranteed.
