Abstract
The supervisory information in pipeline such as the temperature and the pressure difference should be transferred by the smart plug, meanwhile the actions such as the plugging, plugging releasing, and safe preparedness starting should be realized according to the outside control instructions. Therefore the special low-frequency modem should be designed to solve the communication problems. According to the working principle of the low-frequency communication system and the low-frequency induction communication theory, the low frequency communication system which suitable for the working environment of the smart plug is designed, and the communication protocol is determined; the stable communication carrier of 20Hz is produced by the AVR MCU, and the method for Manchester coding and decoding based on the AVR MCU is put forward. The low-frequency communication system has good applicability which can be verified by the experiment.
