Abstract:
Aiming at the shortcomings of motors status remote monitoring in industrial production field, a remote monitoring system for motor operation status was designed based on long-range radio (LoRa) wireless network technology. The motor’s status information such as vibration speed, acceleration, displacement, temperature and other status information was acquired through sensors. This data was subsequently transmitted to a remote computer using a LoRa wireless network, achieving remote monitoring of the motor’s operational status. An alert signal was triggered in case of any anomalies in the motor’s operation, indicating the need for taking effective intervention measures. The information transmission network employed a master-slave architecture, with a single receiving terminal communicating with multiple acquisition terminals to achieve monitoring of the operational statuses of numerous motors in an industrial plant. The motor status monitoring system is designed with an independent power supply for ease of installation and maintenance. Ultimately, an experimental platform is established to perform functional tests on the designed monitoring system. The results show that the designed monitoring system is capable of acquiring the motor's status information in real-time and with stability, thus verifying the system’s stability and reliability. The application of this system is beneficial for ensuring the safe operation of motors and maintaining the regular progression of production.
