With the development of power system automation technology, the combination of motors and communications is becoming increasingly close, and data monitoring methods are also changing. In traditional motor monitoring methods, the monitor and the monitored object are fixed, and neither end can move at will; and it is not easy to monitor remote and remote areas. Therefore, the traditional method can no longer meet the growing requirements of the power system. GPRS uses packet switching, and only occupies wireless resources when actually transmitting and receiving data. The wireless transmission system based on GPRS can realize remote wireless data transmission, and the networking is convenient and flexible. With the promotion of Internet technology and the development of GPRS communication technology, GPRS network communication has immeasurable development prospects with its lower price and always-on performance. Wireless transmission terminals also have broad application prospects in all walks of life. This paper first introduces the characteristics and applications of GPRS technology, as well as the transmission protocol based on the GPRS network, and then proposes a design scheme for wireless transmission terminals based on GPRS. The basic idea is to connect the GPRS transmission terminal to the Internet via the GPRS network to realize data exchange between the data terminal and the monitoring center. In the design, Rabbit2000 with embedded TCP/IP protocol is selected as the control module, and SIM100 is selected as the wireless module. Rabbit2000 microprocessor is an MCU designed by Z-World Company of the United States for Internet-oriented embedded systems. It solves the problems of storage space, running speed, network communication and program development. The hardware and software design of the system are given in this paper. The hardware includes the storage expansion of the control unit, the interface circuit with the module and the peripheral circuit. The software design is written in Dynamic C language, which mainly includes two parts: PPP protocol and data transmission implementation. On the basis of realizing data transmission, UDP and TCP transmission methods are compared to select a solution suitable for remote monitoring of motors.
