In view of the low noise control precision of large equipment and the utilization ratio of equipment, a design method of large equipment noise remote control system is put forward. The RFID module mainly realizes the data query, display and storage, MFRC522 information acquisition module by reading the electromagnetic wave signal and Mifare reader card sent to transfer information, the receiver of the Mifare card signal for further processing, complete the design of decoding and demodulation circuit. The switch module collects the power line current signal and judges the system running state. The software part of the system transmits all kinds of data of the equipment to the host of the system through the data transmission method, and completes the remote control of the noise of the equipment. The experimental results show that the designed system can control the noise of large equipment efficiently and remotely, thus ensuring the safe and stable operation of the large equipment noise remote control system.
